The summary above is based on 18 interviews we conducted recently with Trellix Collaboration Security and Abnormal Security users. To access the review's full transcripts, download our report.
"Defender helps us prioritize threats across our organization."
"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."
"Microsoft Defender for Office 365 helps people to work remotely. It is a secure solution. We don't need to use our company's computers or get VPN connections to the networks. I can control how they share screens and what they send to the devices. It keeps our organizations confidential and sensitive information safe."
"The two main features that prove most beneficial for us are URL scanning and attachment scanning."
"The most valuable feature of Microsoft Defender for Office 365 is the ease of use."
"The product is not resource-intensive."
"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's scalability is good."
"What I like about Abnormal Security is that it notifies me if any of my partners or suppliers are experiencing a security breach by analyzing their database and identifying potential cyber threats."
"The features that appeal to me most are the combination of auto-remediation and Detection 360."
"It does some really cool stuff that other tools aren't doing. We found it to be really effective, and the AI/ML functionality is really what differentiates them."
"Their ability to take things out of the mailbox and catch things much faster than users is excellent."
"Ease of use is undoubtedly one of the most valuable features of Abnormal Security."
"I have never encountered any stability issues with Abnormal."
"One of the things that I love about them is that the setup and installation are super easy. All you do is give them access to your Microsoft 365 tenant, and through APIs, they are able to do their work. They are doing all this through APIs, so you do not have to install the software and take a month to get it all set up to even see the value of the solution. You could be up and running in less than an hour."
"Initial auto-remediation allows us to auto-remediate before the email lands in the end user's inbox for a split second."
"The initial setup is simple."
"The auto-remediation feature is valuable."
"The product protects my email."
"The product helps reduce the number of malicious emails reaching the user's inbox."
"FireEye Email Security is easy to use."
"The solution's most valuable feature is its simplicity. It's very user-friendly."
"We have had very good results from the use of FireEye Email Security. We are very comfortable with this technology, but I don't know if it's necessary to move into the cloud, we will check other technologies and study them. Additionally, the solution has good integration."
"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."
"We noticed that from time to time, Microsoft's stability does have problems. Sometimes the service goes up and down. Sometimes they change without prior notice."
"Microsoft should provide more documentation for users so they can self-educate. I would like to see more documentation for advanced security features."
"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."
"Several simulation options are available within 365, and the phishing simulation could be better."
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"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."
"I'd like some additional features any product can give me to protect our environment in a better way."
"It would be better if it were more scalable. It depends on the architecture, but we would like to make it more scalable for both data centers."
"The biggest pain point for us is the lack of support for on-premise email systems."
"When we're working on something as engineers, and we find an idea or a method of doing something that would be greatly improved by doing it another way, there should be an ability for me to click the ideas button, type in an idea that I have, and submit it to a product review team or developers to have them think through the process a little bit more."
"The ideal scenario would be for Abnormal Security to work in tandem with Microsoft to analyze incoming emails."
"I, as such, do not have anything that I do not like or would like to add, but you could argue that because they are doing it API-based, there is a chance that something could slip through temporarily before they are able to pull it out. In theory, it could happen just because of the nature of the system. They are not in line with the delivery of the mail. They are kind of asynchronous, which is a pro as well as a con. If it is synchronous, then I know it would always stop them, but because it is asynchronous, things could get through temporarily or because of some system issues on the Microsoft side or their side. It is the nature of the beast, but it is a little bit of a con."
"The pricing for academic institutions and student mailboxes is challenging."
"I would like to have the ability to customize the auto-remediation feature."
"One feature I'd love to see is outbound scanning."
"There could be room for improvement in enhancing integration with other cybersecurity tools."
"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."
"The custom tailoring is limited."
"Sometimes especially zero-day spam emails can be passed to the user's inbox."
"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 needs better support."
"I would like to see this solution become more flexible."
"The reporting aspect of the solution needs improvement."
"In general, our company should make the tool more robust to protect our systems."
