Announcing our $20M Series A to redefine email security

Sublime, an email security company, recently raised a $20 million Series A led by Index Ventures and is revolutionizing the email security landscape with its innovative approach. Founded by a team with extensive experience in offensive cybersecurity, the company aims to address the limitations of traditional email security solutions by providing a transparent, customizable detection engine called Message Query Language (MQL). This approach allows users to tailor detections and responses to their specific environments, overcoming challenges like vendor bottlenecks and one-size-fits-all models. Since its public launch in February 2023, Sublime has been adopted globally, with hundreds of deployments preventing millions of email-borne attacks. The platform, which is open-source and interoperable across major platforms like Microsoft and Google, emphasizes community collaboration against emerging threats using detection-as-code. Sublime's focus on automation and customizability has made it accessible to a wide range of organizations, from Fortune 500 companies to small IT teams, while its free and paid offerings encourage widespread adoption and shared value. As the email threat landscape evolves with technological advancements like generative AI, Sublime continues to innovate to stay ahead, maintaining its commitment to transparency and community-driven security solutions.
