Tolu Omolaja - PeerSpot reviewer
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.

Stable, but malware needs improvement and customer support is poor
They need to improve the malware in the product. I am not satisfied with Clearswift because of the lack of customer support. The support is poor, the supplier takes a lot of time and it's expensive. We have some issues here when I contact the supplier, it takes a lot of time for them to get back to us but there's no solution. I am now looking at Symantec as a possible alternative.

Quotes from Members

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

Pros

"My experience with customer support and technical support for Microsoft Defender for Office 365 has been excellent."
"The initial setup is straightforward. You just add the license, click it, and then you can set up the rules. It is quite simple."
"Defender enables us to secure all 365-related activity from a single place. It gives us visibility into everything happening in Outlook, protecting us against phishing and other email-based threats. Defender helps us detect any suspicious behaviors."
"It’s easy to handle integrations, and we don't need a lot of people in our IT team."
"Defender for 365 is a comprehensive cloud-based solution. The value of the cloud is that you aren't alone. Threat intelligence and analytics are shared in the cloud. We don't have to find the solution alone. If you face an unknown threat with traditional solutions like Trend Micro and Symantec, you need to open a case and send your information to them to analyze forensically and identify the source of the attack."
"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."
"The two main features that prove most beneficial for us are URL scanning and attachment scanning."
"The product is not resource-intensive."
"Ability to create your own content-filtering policies with relative ease."
"A stable solution."
"The solution's ability to operate without placing a heavy burden on our system resources is particularly commendable."
"The most valuable feature of the solution is the ease of deployment."
"Trend Micro Worry-Free Services Suites has an inbuilt auto scan facility."
"Trend Micro effectively detects and blocks NAS devices and identifies potential threats."
"Trend Micro Worry-Free Services Suites has an inbuilt auto scan facility. It is very good at detection and response, and it includes a web filtering option."
"The load balancer feature is excellent."
"We use the solution for endpoint protection, malware detection, and detecting unsafe web access."
"The solution offers a comprehensive solution that includes antivirus, malware protection, ransomware protection, web filtering, and device control features. It provides networking capabilities, making it a robust solution for comprehensive security needs."
 

Cons

"We need a separate license and we don't know how to get the license that is required."
"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."
"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."
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"Microsoft Defender for Office 365 should be more proactive."
"Microsoft Defender for Office 365 must improve the overall management style, including the GUI. It also needs to change the filters so that it is easy to whitelist and blacklist data."
"Configuration requires going to a lot of places rather than just accessing one tab."
"I'd like some additional features any product can give me to protect our environment in a better way."
"Malware needs improvement."
"FTP server and TRUST Manager functionality."
"Network vulnerability scanning could be improved."
"Trend Micro should improve its Worry-Free Services Suites, particularly the agent for Windows operating systems."
"The solution’s scalability is limited."
"The solution's documentation is not good, and I'm struggling to change global configurations."
"The log management feature needs to be improved, specifically, the ability to send logs from the console via API."
"The licensing aspect seems costly, and the license cost increases yearly, which is a concern for us."
"The EDR part of the product is an area of concern where improvements are required."
"The pricing of Trend Micro is a little bit higher compared to Sophos."
 

Pricing and Cost Advice

"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"It's a user-base subscription."
"The solution could be better by simplifying the business model of their licensing. It was hard to figure out how to get the licensing done for the environment, initially."
"Defender for 365 comes in various plans and licenses, along with other Microsoft security solutions. Purchasing this kind of package or security bundle gives good value for money, and that's what I recommend."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"For licensing, it's usually a yearly package for customers who are subscribed to Office 365, but they can also pay on a monthly basis."
"The license is expensive because the cost is based on the number of users."
