I have yet to find something I dislike about the product. Review collected by and hosted on G2.com.

We recently swapped our SEG from a competitor to Sublime and the experience so far has been excellent. Sublime’s team and our CSP have been readily available to bring our team up to speed and aid in making the transition seamless. Having full transparency over our detection rules has elevated our teams ability to detect and respond to email threats. Review collected by and hosted on G2.com.

There is a significant learning curve required to fully utilize Sublimes capabilities, specifically regarding MQL. However, Sublime overs public and private training sessions to increase our ramp up rate. Review collected by and hosted on G2.com.

I love how easily it is it implement, its effectiveness, and how transparent the whole software is about what it detect & why. You will very quickly see a return on investment due to much cleaner inboxes, rid of malware, phishing attempts and other attacks. They continually add new features and detections. I feel sublime is the best email security platform out there right now, and one of the strongest tools at our disposal. Review collected by and hosted on G2.com.

Sublime Security is our number one email security tool. The ability to write incredibly specific rules for your environment with the MQL language combined with the seemingly ever-present rule updates from Sublime is very reassuring. We use it every day and their customer support is some of the best. Review collected by and hosted on G2.com.
