Sublime Security Reviews Summary
Author infoRatingReview Summary
Manager Security Operations Center at a educational organization with 10,001+ employees4.5Sublime Security significantly improved our email threat detection, offering detailed analyses, reliable automation, and strong scalability. It's easy to implement, integrates well, and replaced our previous vendor without increasing headcount. I'm very satisfied with its performance and support.
Security Engineer at a financial services firm with 201-500 employees3.5I've used Sublime Security in a proof of concept and found its customizable rules valuable, though tuning them requires effort. It's stable and scalable, but false positives create overhead. Overall, it's promising but needs some improvements.
Head of IT at a manufacturing company with 51-200 employees4.5I use Sublime Security for email security, appreciating its detection and blocking capabilities. However, end-user access to the quarantine box needs improvement. Comparing it to Microsoft Defender, I find it more proactive in stopping malicious emails.
