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.
Partner Account Manager at a wholesaler/distributor with 51-200 employees4.5I rate Sublime Security 9/10 as an advanced email security platform. It combats sophisticated threats and enhances existing systems, offering clear ROI. However, it requires a learning curve, and its cost might deter smaller businesses.
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.
