The ability to automate remediations with high confidence and minimize manual reviews unlocks a new level of efficiency in our SOC. It’s hard to imagine going back to life before Sublime.

Sublime’s detection capabilities are really only limited by the administrator’s imagination, which is a far cry from any other email security platform on the market. Combining that with the Sublime team’s constant innovations and new rulesets, they’ve become a critical piece of our security stack and have been an incredible partner for us.

Director, Information Security

We made the decision to double down on tools and partners that prioritize automation, orchestration, and great user experience for security engineers. The Sublime team has met all our needs and more—the platform is a huge value-add to our enterprise security tool suite.

Rajendra Umadas
Director of Security

The Sublime team has been incredibly responsive and our feedback loop is very tight. Their passion for this is easy to see and feel.
