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.
"Does a thorough job of examining email and URLs for malicious content."
"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 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."
"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."
"The most valuable feature is protection against malicious links, fishing, and impersonation. You can train people to be aware of these threats, but they're not always careful. When they're using their phones between meetings, they click on a link, and it's game over."
"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."
"Threat Explorer is one of the features that I very much like because it is a real-time report that allows you to identify, analyze, and trace security attacks."
"Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."
"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."
"Ease of use is undoubtedly one of the most valuable features of Abnormal Security."
"Initial auto-remediation allows us to auto-remediate before the email lands in the end user's inbox for a split second."
"I have never encountered any stability issues with Abnormal."
"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."
"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."
"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."
"We can control this solution from the cloud and are able to access it from wherever we are."
"FireEye Email Security is easy to use."
"FireEye Email Security helps us prevent spam and phishing emails and all other business-compromised email attacks."
"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."
"The product helps reduce the number of malicious emails reaching the user's inbox."
"FireEye is good for malware depicting and security."
"The initial setup is simple."
"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."
"The company should focus on adding threats that the solution is currently unable to detect."
"Microsoft should provide more documentation for users so they can self-educate. I would like to see more documentation for advanced security features."
"Configuration requires going to a lot of places rather than just accessing one tab."
"Several simulation options are available within 365, and the phishing simulation could be better."
"We need a separate license and we don't know how to get the license that is required."
"The UI needs to be more user-friendly."
"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 biggest pain point for us is the lack of support for on-premise email systems."
"The ideal scenario would be for Abnormal Security to work in tandem with Microsoft to analyze incoming emails."
"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 pricing for academic institutions and student mailboxes is challenging."
"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."
"One feature I'd love to see is outbound scanning."
"I would like to have the ability to customize the auto-remediation feature."
"There could be room for improvement in enhancing integration with other cybersecurity tools."
"The spam detection feature could be better."
"I would like to see this solution become more flexible."
"FireEye needs single sign-on. They say it's on their roadmap. They should also implement support for Microsoft Authenticator app for 2FA."
"If they want to be the primary or best solution, they need to have better email management features."
"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 reporting aspect of the solution needs improvement."
"The solution needs better support."
"Sometimes especially zero-day spam emails can be passed to the user's inbox."
