Great URL scanning and attachment scanning, but I would like more proactive threat analysis
The two main features that prove most beneficial for us are URL scanning and attachment scanning. URL scanning involves an automatic scan of links and emails. When a user clicks on a link within an email, the system promptly checks the link's safety. If the link is deemed safe, access is granted automatically. However, if it is flagged as unsafe, we receive feedback and notification to caution us about the potentially harmful link. At this point, we are presented with the option to proceed or return. I have personally witnessed the system identify a few unsafe links, making this the primary advantage of using the solution. The second crucial aspect is the scanning of attachments. When an email containing an attachment arrives, we receive a notification of the new email, along with information that the attachment is being scanned for threats. This additional layer of security provides peace of mind for our organization. While Microsoft Defender for Office 365 offers numerous features, these two stand out as particularly impressive and valuable to us.

Provides strong email filtering and threat intelligence but pricing needs improvement
I work with SonicWall Email Security SonicWall Email Security uses multi-layer cloud security. It filters emails before they come to my provider, such as Office 365. It has real-time threat intelligence and provides strong data loss prevention. Additionally, it filters emails before they reach my…

Has an easy implementation phase to deal with for users
I primarily use the product in our daily security operations since it is implemented in all of our company's systems and is used in our environment. Normally, email security tools like FireEye or Trellix help to protect ourselves from spam, malware, and other email-oriented threats. The tool is used extensively in our company's environment. It is more like a collaboration email security that is used in our company. Whether my company plans to increase the number of users of the product or not is something that depends on the growth of the organization. I recommend the product to those who plan to use it. The product is stable and reliable, considering the results my company gets out of it. When it comes to Trellix or FireEye Endpoint Security (HX), the tools offer antivirus as well as the modern real-time security feature, which is used to automate the detection and protection of the endpoints against all the security threats that are currently there in the industry. I don't see any challenges with the integration part of the product, but since a different team manages it, I don't have visibility into it. In terms of the value offered by the product, the solution does help our company protect data and the complete infrastructure. I rate the tool a nine out of ten.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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."
"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 most valuable feature of Microsoft Defender for Office 365 is the ease of use."
"The good part is that you don't have to configure it, which is very convenient."
"Microsoft Defender for Office 365 facilitates efficient management and updates through the cloud. We do not have to worry about incompatibilities. It just works."
"The risk level notifications are most valuable. We get to know what kind of intrusion or attack is there, and we can fix a problem on time."
"Our customers are satisfied with Defender for 365 because Microsoft products are easy to use and customize to meet the client's needs. Everything is in one place, so we can adjust policies as needed for phishing, DLP, ATP, or any other security features that our clients want to apply."
"The product is not resource-intensive."
"The anti-spam aspect of the solution is its most valuable feature."
"SonicWall Email Security uses multi-layer cloud security."
"The most valuable feature is that it protects from spam."
"It is a very scalable solution."
"Beside a few issues with specificity in the email protection controls, this product is very good at handling email security."
"This solution provides very good email security that protects us against spamming and malware."
"The most valuable features are the anti-spam, anti-phishing, anti-virus, and anti-spoofing."
"The product is easy to manage in terms of configurations."
"FireEye Email Security helps us prevent spam and phishing emails and all other business-compromised email attacks."
"FireEye Email Security is easy to use."
"I like FireEye's filtering, spam digests, and its advanced threat review of email flow. It also has a broad range of riskware rules you can deploy."
"One of the most valuable features is the protection against vulnerabilities, particularly through virtual patching."
"One of the valuable features of the product stems from the fact that it is easy to implement the tool in our environment."
"What I find most valuable with the solution is that it can integrate with cloud solutions, such as Google and Microsoft. Additionally, the solution is easy to use."
"The product helps reduce the number of malicious emails reaching the user's inbox."
"The solution's most valuable feature is its simplicity. It's very user-friendly."
 

Cons

"There's room for improvement regarding the time frame for retrieving emails."
"The XDR dashboard has room for improvement."
"The visibility into threats is not up to the mark, as I do not have control. I rate my experience with Microsoft Defender for Office 365 as six out of ten due to troubleshooting and pricing concerns."
"The only thing they should improve is the licensing model. They should stop changing it. A year ago, the five features I mentioned were included in one product. Now, three of them are bundled into one product, and you have to pay extra for the other two. I don't mind paying extra, but I don't want them to change it every year or every six months. I need to know what I'm looking at and not worry about it next year."
"We are always looking for others tools to increase automation on tasks. There can be better integration with other solutions, such as PowerPoint and email."
"Microsoft security solutions work as expected. They are constantly updating the solutions to make them better. At the same time, the changes can impact a customer's environment, and we need to adjust settings. Sometimes we aren't aware of the changes, and nothing is pushed from the backend automatically."
"The certification training for Defender for 365 needs to be deeper and incorporate Sentinel. I took all the security courses except one, and Sentinel isn't included."
"They can improve their security in a way where a customer can know if all their attachments are safe or not to open through a report. The solution does its job perfectly, but it never reports to the customer whether those attachments have been stopped before or not."
"The reporting needs improvement."
"SonicWall Email Security could improve by making the file blocking and the release feature easier to use"
"The platform's control panel needs enhancement."
"Updates could be released more frequently."
"They need well-trained partners in Nigeria."
"The pricing could be improved."
"The protection level for email security isn't 100%. I'm still getting some spam and junk mail."
"There could be definition updates included in the subscription."
"If they want to be the primary or best solution, they need to have better email management features."
"The solution needs better support."
"The reporting aspect of the solution needs improvement."
"I would like the solution to be able to automatically quarantine the malicious emails before getting to the user's mailbox and continue with regular email operations. This could result in the user clicking the email before the purge operation is completed."
"Sometimes, integration can be challenging, impacting its stability, which is why I rate it a five out of ten."
"I would rate them as a 1.5. The new hub created in India is not good."
"FireEye needs single sign-on. They say it's on their roadmap. They should also implement support for Microsoft Authenticator app for 2FA."
"The solution is not easy to set up. However, we have employees that have the knowledge that can do the difficult implementation. It would be better if the process was easier."
