Microsoft Defender for Office 365 Reviews

365 Defender is a critical tool for mitigating attacks and preventing threats. We use it for email filtering and blocking phishing attacks throughout the entire enterprise. We have around 1,500 users. 

365 Defender has improved our security across multiple categories. It's effective against advanced attacks like phishing and ransomware. Defender's attack disruption works well if you have a strong policy configuration. It will automatically block threats and filter them in most cases without the need to investigate. It will remedy the threat immediately. 

The automated response reduces the manual work, saving our security team time. I would estimate it saves about six hours per day. 

Defender is a SaaS platform, so it offers more flexibility. Managing the permissions is easier. The solution's automated detection and response features are scalable. It's a unified solution that doesn't just cover Microsoft products. We're a multi-cloud shop, and having that coverage is critical. It also includes the latest IAM features like two-factor and multifactor authentication, giving us the most robust solution.

You should be able to deploy Defender for every subscription without the need to add servers.

Positive

We used alternative solutions prior to implementing Microsoft Defender for Office 365. We selected it due to its superior integration with our existing security infrastructure.

The implementation was completed in-house.

We evaluated other solutions before switching to Microsoft Defender for Office 365.

I would rate Microsoft Defender for Office 365 ten out of ten.

I am the IT director for my organization, a small municipality with a population of 20,000 located in New Mexico. We employ 250 staff members. Our cybersecurity measures encompass a wide range, including endpoint management and the utilization of Windows Defender for Office 365. This software is internally deployed and primarily focuses on monitoring our email systems. This is where the most intricate configuration is applied. It examines our email traffic, aiming to prevent a significant amount of spam and numerous phishing attempts, although it cannot catch everything due to inherent limitations, it effectively performs tasks such as antivirus and antimalware functions within our email communication.

I would rate the visibility into threats eight out of ten.

Microsoft Defender for Office 365 assists to some extent in prioritizing threats across our enterprise, but it is not our primary tool for this purpose. I would rate the significance of this capability in Microsoft Defender for Office 365 a five out of ten.

I also utilize Windows Defender for both our desktops and mobile devices running on iOS and Android. Additionally, we employ Azure AD for authentication. All of these solutions have been seamlessly integrated into a unified dashboard. This integration process is highly straightforward and occurs automatically during the setup phase.

Our integrated solutions all work natively together to deliver coordinated threat responses.

Microsoft Defender for Office 365 assists in automating routine tasks and identifying high-value alerts. This has led to a 100 percent improvement in our security operations, as we had not implemented anything prior to the adoption of Microsoft Defender for Office 365.

Microsoft Defender for Office 365 has aided in decreasing the number of dashboards we need to monitor, although it does not eliminate all of them. As a cybersecurity practitioner, I still require external vulnerability management for certain third-party risk assessments; Microsoft Defender for Office 365 does not cover those aspects. Consequently, I utilize a separate product for that purpose.

It currently lacks built-in security awareness features. However, efforts are being made to develop such features. The initial stages of the security awareness program can already be observed in the Microsoft platform. Defender for Office 365 provides us with a tool called Safe Links, which enables us to analyze attachments, including both files and data. If someone attempts to access content that is later identified as malicious, we receive a notification. This allows us to identify users who may have interacted with harmful content to some extent, addressing active and potentially harmful interactions. If an individual receives a suspicious link, Safe Links examines the link for potential phishing characteristics. Although the link's malicious nature might not be immediately apparent, it is delivered within a protective Safe Links wrapper. Consequently, if the recipient clicks on the link, this action is logged within the Microsoft environment. Later, if the link is identified as part of a credential phishing attack, appropriate measures are taken. This includes deleting the associated email and notifying the user who clicked on the link. Subsequent actions may involve remediation, such as password changes if deemed necessary. This integration works seamlessly and proves to be highly effective.

Microsoft Defender for Office 365 has helped our organization save around 20 hours of work time.

It saves our organization money. No one would accuse the Microsoft product of being cheap or inexpensive. However, the reality is that most of the security functionality is included in the licensing that I need to purchase to support my operation. In other words, I'm not buying these security products separately; I'm obtaining them as part of my Microsoft 365 licensing. It's not an add-on; they are required components of the government cloud licensing that I have purchased. Therefore, I must acquire Microsoft 365 to access applications such as Office, SharePoint, OneDrive, Exchange, and others. The security features are all integrated within this package; I don't need to source them from elsewhere. Additionally, I would have had to pay for the performance products regardless.

There are several features that I consider valuable. These include anti-malware and anti-phishing capabilities, along with certain remediation abilities for addressing issues once identified. Moreover, the system allows for easy reporting of problems. In the event of a phishing attack, we can conveniently initiate a comprehensive search to identify all related elements of the campaign and remove them from users' mailboxes.

Additionally, the platform offers anti-spoofing measures targeting well-known high-value targets. This proactive approach helps in mitigating business email compromise by designating our high-value personnel. Consequently, any communication purporting to originate from these individuals undergoes a more rigorous verification process to ascertain its authenticity and whether it genuinely stems from a valid account associated with the respective individual.

Microsoft Defender for Office 365 lacks proactivity in assisting us with preparing for potential threats before they occur. While they employ a substantial amount of threat intelligence to preemptively prevent incidents, their effectiveness diminishes when it comes to delivering proactive threat intelligence alerts from Microsoft. Their focus primarily revolves around managing the internal environment. On the other hand, my other vendor, Check Point, along with my membership in MS-ISAC, supplements me with this type of information. 

The phishing and spam filters could use some improvement. It is adequate, but it doesn't match the quality of Proofpoint or Mimecast. However, it comes close in effectiveness. Plus, if we're obtaining it for free, investing in the other products seems impractical.

I have been using Microsoft Defender for Office 365 for around seven years.

Obtaining technical services is challenging.

Negative

I would rate Microsoft Defender for Office 365 eight out of ten.

I would rate the comprehensiveness of our integrated Microsoft products for threat protection a six out of ten.

We use Microsoft Defender for Office 365 for our endpoint security.

Microsoft Defender for Office 365's visibility is good.

Microsoft Defender for Office 365 helps prioritize threats across our enterprise by using an endpoint.

Integrating with other Microsoft solutions is generally straightforward, as everything can be managed from a single console. However, there are some cases where the integration process can be complex, such as when it requires accessing a different dashboard. Overall, the benefits of managing multiple Microsoft solutions from a single place outweigh the occasional complexity of integration.

Our solutions work together natively to provide coordinated detection and response across our entire environment. This coordinated detection provides high-quality results because it is easy to check emails and endpoints for threats. We chose to bundle the solutions because of their ability to integrate.

Coordination and integration are essential in cybersecurity because there are many resources to monitor. The ability to coordinate and integrate from a single source makes it easier and helps to eliminate the need for multiple products.

Microsoft Defender for Office 365 has improved our security posture, especially around email. It integrates easily with our other Microsoft solutions and provides good visibility into our systems.

Microsoft Defender for Office 365 helps automate routine tasks.

Automation allows us to focus our resources on critical issues instead of the standard security tasks that can be automated.

Microsoft Defender for Office 365 saved our organization time.

Microsoft Defender for Office 365 increased our productivity, which resulted in cost savings.

Microsoft Defender for Office 365 helped decrease our time for detection and response. 

Microsoft Defender for Office 365's most valuable feature is its performance.

The ransomware protection is good.

Microsoft Defender for Office 365 is a comprehensive security solution, but it could be improved. Compared to other solutions, Microsoft Defender for Office 365's security reports are not as detailed and the visibility into our network coverage could be better.

The IOC scanning has room for improvement.

The XDR dashboard has room for improvement. The dashboard needs more of a single pane of glass because currently, Microsoft Defender for Office 365 does not give me any options to scan an email thread or attachment for IOCs on my endpoint. I need to manually download the file from the email and then scan it with Microsoft Defender for Office 365. I think Microsoft Defender for Office 365 should be able to scan email threads and attachments directly, without the need for manual intervention.

Secondly, the Data Loss Prevention functionality in Microsoft Defender for Office 365 is very limited. It can only scan for certain types of data. Microsoft Defender for Office 365 should be able to scan for a wider variety of data types, such as customer lists and intellectual property.

Attack process management and breach attack simulation should be included in Microsoft Defender for Office 365.

I have been using Microsoft Defender for Office 365 for six years.

Microsoft Defender for Office 365 is stable.

Microsoft Defender for Office 365 is scalable.

Technical support is generally helpful, but we often need to escalate tickets to resolve issues.

Neutral

I previously used Kaspersky Security for Mail Server, Trend Micro Email Security, CrowdStrike, and Mandiant. However, my organization now uses Microsoft Defender for Office 365. This is because we are a Microsoft customer and it makes sense in terms of cost and integration.

We have seen a return on investment using Microsoft Defender for Office 365.

Compared to other brands, Microsoft Defender for Office 365's pricing is competitive.

I give Microsoft Defender for Office 365 an eight out of ten.

The maintenance is seamless.

A single-vendor approach is better than a best-of-breed approach because it provides a more integrated and seamless solution. This means that there is no need to worry about compatibility issues or data silos and the overall security posture is better.

Microsoft works hard to provide customers with a single pane of glass so they can easily manage, scale, and maintain their solutions. I recommend Microsoft Defender for Office 365.

We mainly use Microsoft Defender for Office 365 to secure our Office 365 combined application package, which includes Outlook, Word, Excel, PowerPoint, OneDrive, Skype, and Teams. We have all of these combined packages in our cloud. 

Before we deployed Defender, we didn't have the right solution to safeguard these applications because our data was moved from multiple locations, from Outlook to OneDrive, for instance. After the introduction of Defender, we could instantly control most threats.

We also use Microsoft Defender for Identity and Cloud Apps. We deployed Identity recently. 

Integration is easy because Microsoft is the vendor of all of these security products. Most of these products are closely integrated, whether they're on-premise or deployed on the cloud.

These solutions work natively together to deliver coordinated detection and response across our environment. All of these features work on different security layers to ensure protection. Microsoft Defender for Identity gives protection to users. That's an application layer. Simultaneously, Defender for Cloud also provides a layer of security. Each Microsoft product offers a different layer of security, so our organization is secure.

These security products offer comprehensive threat protection. Each day, thousands of people send emails that contain malicious content. Microsoft Defender for Office 365 constantly monitors those attachments and gives us alerts so that we're able to focus on threats and prioritize them accordingly.

We use the bidirectional sync capabilities. It's an important feature to us because we need it for proper syncing and security, both on-premises and on the cloud.

The solution is deployed on a public cloud.

Defender is used in one tenant, and multiple departments use it. It provides security for about 2,000 users.

We have seen multiple benefits from using Defender. Our data was on-premises about five years ago. We migrated our data to the cloud to improve our security. It's awesome to get all of the security features in the cloud. To apply these features on-premises requires different hardware and multiple vendors. With Microsoft Defender, we're able to have a single manufacturer.

Microsoft Defender for 365 helps automate routine tasks and the finding of high-value alerts. It's a detection mechanism, so it doesn't solve the issue, but it will give us alerts and other notifications. It provides system alerting and patches.

The alerting automation definitely affects our security because our organization requires alerts constantly. The Defender setup for Office 365 applications gives us a clear alerting dashboard. The dashboard has multiple features that are linked to most of our applications, so it's more secure.

This solution helps eliminate the need to look at multiple dashboards. With different vendors for security, we obviously had vertical dashboards. Microsoft Defender gives us a single dashboard that we can link to other applications. 

Defender has reduced time spent by 50%.

It definitely saves us money because other vendor products cost more. The hardware itself costs money. Defender's subscription costs less. We have saved 50% compared to other solutions.

Defender decreases the time it takes to detect and respond. We're able to detect 20-30% faster.

Most of our files are being stored in OneDrive. We need to safeguard those links because users have to forward them to multiple locations. Microsoft Defender has a feature to protect each and every attachment. Even if it's an encrypted attachment, it will check for any potential threats.

If there are any spam contents in an email, we will be notified. With the implementation of Defender, we're able to correctly monitor attachments, files, and safeguard the required data. 

Microsoft Defender for Office 365 provides us with visibility into threats. Our emailing system is Microsoft Office Outlook. We also use a mail server from Microsoft. If there's an issue, we're able to troubleshoot it right away and give a solution. All of the administrators are properly alerted in their dashboards.

Microsoft Defender for Office 365 helps us prioritize threats across our enterprise. It safeguards us from any incoming threats or viruses. It scans every bit of information from the software cloud, including attachments, links, or malicious emails that hackers generate to break the security system.

It's definitely important that Defender helps us prioritize threats across the enterprise because some of the security breaches are less serious, so there is more time to troubleshoot. We're able to see everything in the dashboard, so we're notified about the important threats and can act accordingly to resolve them.

The advanced threat protection requires awareness and knowledge from administrators. Microsoft should provide more documentation for users so they can self-educate. I would like to see more documentation for advanced security features.

I have used this solution for about five years.

It's completely stable.

It's scalable.

Technical support is really good. I would rate them as nine out of ten.

Positive

We haven't used any other solutions.

The setup was straightforward.

Maintenance isn't required because the solution auto-updates.

We received support from Microsoft for implementation. Four system administrators were needed for implementation.

We have definitely seen a return on investment. OneDrive stores a lot of data, and maintaining the security of that data is a large task. It would be expensive to integrate another solution for that task. Since implementing Defender, we have saved a lot of money.

There are other Microsoft products included in the package, so we're able to save more money. I think there's a great return on investment.

The pricing is normal. Considering its popularity, it's not overpriced.

We haven't evaluated other options. To secure Microsoft Office 365 applications, we wouldn't necessarily go for other third-party solutions because Microsoft has its own proprietary solutions.

I would rate this solution as nine out of ten.

My advice for other people who are in security is to try Defender. It's much better than other top security appliances and it's completely affordable. For large and medium enterprises, it's definitely worth trying because applications like OneDrive require constant monitoring. 

Multiple security solutions must be monitored constantly, and the maintenance cost will be much higher. Dependency issues will arise, and you will need multiple support people to troubleshoot issues. Sometimes the issue won't be found if it involves multiple dependencies from other vendors. We prefer to go with a single-vendor product like Microsoft because of their support.

We are using Microsoft Defender for Office 365 primarily for security purposes.

The integration with Office 365 is seamless, and we don't need a large IT team to manage it. It helps in maintaining the basic security functions without additional complexity.

Since we are using the basic version, we find that it covers most of our requirements without needing additional configurations. It’s easy to handle integrations, and we don't need a lot of people in our IT team.

Sometimes, phishing emails manage to pass through the filter, so the system needs to enhance its phishing email detection capabilities. We also need alerting features for abnormal actions like unusual logins or abnormal activities in the mailbox.

We have been using Microsoft Defender for Office 365 for seven to eight years.

Stability is generally good; I would rate it an eight out of ten.

Scalability is also quite good. I would rate it an eight out of ten.

Technical support from Microsoft is reliable and meets our expectations. I would rate it an eight out of ten.

Positive

We chose Microsoft Defender as it integrates easily with our existing Office 365 setup, and we do not need to pay extra for security functions.

The setup was easy and not time-consuming. We didn’t need to set up much as it was integrated with Office 365.

The installation was handled by two engineers in our team.

Since we are using the basic functions, we don't need to invest a lot of money. It does help in cost reduction.

The pricing is reasonable since it comes integrated with our Office 365 license.

In our current situation, we are not considering other vendors for this purpose.

Integration with Office 365 is one of the strongest points. I recommend it for easy handling and less need for additional IT resources.

I'd rate the solution eight out of ten.

The benefit that stands out to me is the ability for multiple individuals to collaborate simultaneously within the same document. Additionally, there is the option to save the document directly in the integrated OneDrive or SharePoint. 

Microsoft Defender for Office 365 should improve the troubleshooting tools. It's unclear whether the device is blocked at the firewall level or at the device itself. The granularity needed for troubleshooting is currently lacking.

From my perspective, Microsoft should address this issue to benefit many users who likely share the same sentiment.

I have been using the product for three years. 

Microsoft Defender for Office 365 is stable. 

You can scale up as you pay. 

Evaluating Microsoft support can be a bit mixed. Sometimes, it's good, but not so much. The initial contact is typically with the help desk. When I call, I usually need someone at a higher level, maybe level three, to assist with more complex problems. The challenge is that it can take up to two weeks to resolve issues, and my main complaint is the waiting times and the basic nature of level-one support. Getting to the expert who can fix the problem often takes a couple of weeks.

Neutral

My clients used Norton and McAfee before Microsoft Defender for Office 365. It makes sense in the long term, especially when many clients already have Microsoft 365 in their licenses. Paying more to get the security features with Microsoft instead of additional licensing costs with a different company is a practical choice. It seems to be mainly about saving money.

The tool's deployment is not straightforward. However, it has good documentation. 

The solution is good but not cheap. It offers a big ecosystem where you can manage everything from one place. 

Integrating identity and access management into Microsoft 365 Defender is important for my customers and me. The ability to centrally manage these aspects within the platform is highly valuable. Rather than navigating through numerous consoles to verify various aspects, having almost everything in a single location saves time. This integrated approach streamlines operations and reduces the complexity of learning and managing different products.

Nowadays, everyone uses not just Microsoft products but also third-party ones. It would be good if Microsoft could make its security tools work with all kinds of software. Nowadays, there are so many cyber attacks and security threats. Having one product that can handle and manage all these threats across the board is beneficial.

We have stopped using Trend Micro in a couple of places. I am not sure if it was due to cost or pricing. 

The product is more convenient to manage, and it saves time. Instead of navigating through different controls, having everything in one place allows the security team to take action on threats or issues.

I rate the product a nine out of ten. I have used it for security and compliance. In my experience, they're doing quite well; it's a good product. If people are considering Microsoft products, I would say, why not? It's just that support during implementation could be better sometimes. However, it's a good product with frequent updates. 

Microsoft Defender for Office 365 is used to protect our organization from attacks.

Our deployment is a hybrid model with 80 percent being on the cloud.

The visibility into threats is excellent. A dashboard provides real-time information on emails, blocked emails, blocked files, and blocked URLs.

We integrated Microsoft Sentinel and Microsoft Intune with Microsoft Defender for Office 365. Integrating Intune was a little difficult but we managed.

The solutions work natively together to provide coordinated detection and response across our environment. This is important.

The integrated Microsoft solutions provide comprehensive insights into threat issues through threat analytics.

Microsoft Sentinel allows us to ingest data from our entire ecosystem. This is important because it provides us with a vital security feature that allows our organization to monitor and respond to alerts and threats detected in our enterprise via Sentinel. We have configured custom alerts and triggers in Sentinel, which gives us a better understanding of the threats in our organization.

Microsoft provides a comprehensive view of alerts to help investigate issues and address malicious emails. We can investigate and share feedback in our message tracking log and the threat explorer in Defender to mitigate and resolve the root cause of the issues.

Microsoft Defender for Office 365 saves us time with our investigations.

We now use the cloud to maintain our email as a gateway which has saved us money by not requiring on-prem hardware.

Our time to detect and respond to malicious emails was decreased. The solution provides the CPU resources needed to scan emails for malicious content, and it also makes it easy to track the number of administrative emails sent to users.

Microsoft Defender for Office 365's most valuable features are safe attachments and safe links.

The GUI is sometimes slow to fetch the device report and could be improved.

It would be great if Microsoft Defender for Office 365 were priced at the tenant level, rather than the user level. This is because the feature is used by all users in the tenant, not just individual users.

I have been using Microsoft Defender for Office 365 for two years.

Microsoft Defender for Office 365 is stable.

Microsoft Defender for Office 365 is scalable.

Technical support is often unsatisfactory. When I open a ticket, the initial engineer I speak to often has no hands-on experience and needs to escalate the issue to someone else. This can take a long time, as the engineer needs to check with the internal team before they can provide any assistance. In the end, the issue is eventually resolved.

Neutral

We previously used Barracuda Email Security Gateway, but it did not sandbox emails. After careful consideration, we decided to switch to Microsoft Defender for Office 365.

The initial setup was straightforward. We just follow Microsoft's documentation and fine-tune the default custom policies as well as new days on custom policies for data management and checking. Two people were required for the deployment.

The implementation was completed in-house.

We have seen a return on investment.

The license is expensive because the cost is based on the number of users. The more users there are, the higher the cost.

I give Microsoft Defender for Office 365 a nine out of ten.

We have four people that directly access the solution.

There is no maintenance required from our end.

Before using Microsoft Defender for Office 365, organizations must ensure that the policies are configured correctly to fit their specific needs.

It is better to choose a single vendor with high expertise in a specific area, rather than a best-of-breed strategy.

I work in the industry where we use Microsoft 365 and its associated products like Office Works, PowerPoint, Excel, and Word.

We use Microsoft Defender to help protect our business areas by integrating it with our existing infrastructure, including Azure, which assists in defending the business areas.

We use Microsoft Defender for its ability to integrate with existing business technologies, which is beneficial for protecting business areas.

Configuration at the mid-level could be improved for the support team.

I have about ten years of experience with Microsoft Defender for Office 365.

The solution is very stable, and Microsoft products have general high availability within the company.

Microsoft 365 meets the needs of the company, which suggests that Microsoft Defender is a scalable solution.

We have a premium contract for Microsoft support, which is rated nine or ten. Although I am not directly involved with their support, clients usually appear satisfied.

Positive

I do not have experience with other email security solutions.

The setup is easy and not difficult.

I do not understand the question regarding return on investment.

I do not know the value of the contracts or the cost compared to competitors.

I have not evaluated other solutions for email security.

Configuration for end users is simple, but improvements can be made in mid-level configurations to make it better for the team.

I'd rate the solution eight out of ten.

It allows us to effectively detect and manage malicious URLs within emails. This proactive approach allows your team to identify and resolve security incidents promptly. We optimize our security by incorporating Microsoft's IOCs into both Defender for Office 365 and endpoint protection. This integration prevents our devices from accessing known threats, saving significant time weekly. Centralized management of threat indicators proves highly efficient, potentially saving hours. This comprehensive strategy enhances our proactive security measures across our systems.

When dealing with a large volume of emails, whether received or sent by users, Defender solutions, particularly Threat Explorer, prove to be highly effective. In instances where users may have inadvertently interacted with potentially harmful emails, it enables me to isolate and analyze these emails by placing them in a secure sandbox environment. This insight is crucial for addressing incidents promptly and collaboratively, fostering a cooperative approach to resolving potential security issues within the organization. In Defender 365, we've implemented a dual-pronged approach for automating tasks and managing security incidents. When alerts like a user clicking on a malicious URL occur, data is directed to Sentinel or Log Analytics. A logic app is then employed to analyze the user's actions using Defender for Endpoint, tracking device activities, and making informed decisions. This integrated system enables us to swiftly identify, analyze, and respond to security incidents, enhancing our ability to manage and mitigate potential threats effectively. It has significantly reduced our time to detect and respond to security incidents. While I don't have an exact figure, the impact has been substantial. By consolidating multiple solutions into logic apps and gaining visibility, we can now respond much more efficiently than before. Without this integrated approach, lacking visibility hampers our ability to identify and address potential threats promptly.

Threat Explorer is an invaluable tool for me, and it plays a crucial role in helping me discern the origins of various email campaigns, pinpointing where they emanate from, and identifying the individuals within our organization who are affected. The convenience of having a centralized location for extracting comprehensive data is particularly noteworthy. With Threat Explorer, I can efficiently manage and mitigate the impact of these campaigns by removing problematic emails from mailboxes, all in one centralized location, eliminating the need to navigate through multiple areas. Effectively prioritizing threats across our enterprise is crucial for us, given that the primary avenue of attack is often through phishing emails. By having robust protection in place, we're able to significantly mitigate this prevalent threat, essentially clearing a major portion of the cybersecurity landscape.

There's room for improvement regarding the time frame for retrieving emails. Currently, the limitation allows users to go back only thirty days when pulling emails or conducting related actions. Enhancing this capability to extend the timeframe, perhaps to sixty or ninety days, would be beneficial.

I have been working with it for three years.

It has been reliable. I haven't encountered any instances of downtime or significant bugs; occasionally, signing out and back in resolves minor issues.

In terms of scalability, our institution has expanded with more students and staff, and we haven't experienced any performance issues with Defender for Office 365. It has proven to be effective and adaptable to the growth of our organization. We currently have approximately four thousand staff members.

The support team, not only for Defender for Office 365 but for any issues I've encountered, has been exceptional. Whether reaching out through email or submitting a support ticket, I typically receive a callback within hours. I've never personally faced any challenges in contacting Microsoft support—they've consistently been prompt and responsive. The account managers, or whatever they're officially called, have been quick to answer and address any inquiries, making the support experience highly satisfactory. I would rate it ten out of ten.

Positive

I would highly recommend it as it offers numerous features that can significantly enhance your security posture. Overall, I would rate it ten out of ten.
