Sublime Security, an AI-powered, programmable email security platform, has successfully raised $20m in a Series A funding round.
This significant financial boost was led by Index Ventures, with contributions from earlier investors including Decibel Partners and Slow Ventures. Additionally, cybersecurity luminary Dmitri Alperovitch, co-founder and former CTO of Crowdstrike, has joined the investment and will serve on the Board of Directors.
The raised capital will be strategically invested back into Sublime Security’s platform to enhance customer experience and expand its capabilities. In a world where email threats pose a constant risk, Sublime Security offers a robust defence mechanism for businesses. The company enables security teams to detect and prevent email attacks using out-of-the-box protection and provides comprehensive visibility into cloud email environments.
Sublime Security plans to use the new funding to deepen its technology stack and improve its platform’s performance. The aim is to offer customers more refined controls for customizing detections, reducing attack surfaces, and enhancing threat hunting capabilities. This will further enable businesses to manage and mitigate the increasing number of sophisticated email-based attacks.
Additional features and improvements highlighted by the funding include the launch of Attack Score, a new feature that leverages transparent, explainable machine learning to help security analysts prioritize email threats more effectively. Sublime Security also offers a unique platform that can be self-hosted or used as a hosted SaaS, providing flexible solutions to companies of all sizes.
Sublime Security CEO Josh Kamdjou said, “On the offense, Generative AI enables attackers to rapidly create diverse, sophisticated campaigns at scale, but on the defense, it’s a powerful tool for automated detection, triage, and explainability.
“The Sublime Platform is a modern take on email security that delivers immediate out-of-the-box protection, with the added ability for teams to tailor email security controls to fit organizational needs and benefit from community-driven protections as the threat landscape evolves.”
