Dmitri Alperovitch
Co-founder & Former CTO

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.
