$20 million in Series A investment has been received by AI-driven, configurable email security platform Sublime Security in order to strengthen its cutting-edge strategy for safeguarding businesses from email threats. Decibel Partners and Slow Ventures, two prior investors, contributed to the financing round led by Index Ventures. The additional money will be used toward expanding platform investments and enhancing user satisfaction.
The funding announcement coincides with the appointment of cybersecurity luminary Dmitri Alperovitch, co-founder and former CTO of Crowdstrike, to Sublime’s Board of Directors, signaling a significant endorsement of Sublime’s approach and future direction.
“Given the massive market opportunity for email security, we are excited to see Sublime continue its trajectory of hyper-growth,” said Jahanvi Sardana, Partner at Index Ventures.The 2023 FBI Internet Crime Report, which linked Business Email Compromise (BEC) schemes to losses of over $2.9 billion, emphasizes that email is still the principal vector via which cybersecurity risks enter the world of digital communication. Because of the pervasive underreporting, the real extent of the losses is probably substantially higher. To solve these issues, Sublime Security has developed a platform that not only delivers instantaneous, out-of-the-box security, but also a wide range of customization possibilities to fit unique organizational demands.
By avoiding the opaque, one-size-fits-all solutions that are prevalent in the cybersecurity space, Sublime would stand out. As an alternative, it provides security teams with tools for threat hunting, tailored detections, and attack surface reduction, all of which are visible and flexible. Their technology makes a wide variety of companies’ access to and use of their Core technology possible by integrating easily with cloud email environments and enabling free hosting.
Open-Source Nature
Sublime Security founder and CEO Josh Kamdjou, who spent a decade in various cybersecurity roles at the US Department of Defense and as a private sector red teamer, emphasized the dual nature of generative AI in both fostering sophisticated cyber-attacks and bolstering defense mechanisms through automated detection and triage systems. Sublime’s platform leverages this technology to provide enhanced visibility and control, enabling organizations to proactively respond to email-borne threats.
The open-source nature of Sublime Security‘s Core Detections, available on GitHub, would exemplify the company’s commitment to community-driven cybersecurity. This approach would not only democratize access to cutting-edge security measures but also foster a collaborative environment where businesses can stay ahead of threats. Advanced users can further refine their security protocols using Sublime’s proprietary Message Query Language (MQL), which integrates with major email services like Microsoft 365 and Google Workspace.
Sublime’s market traction would be evident in its rapidly expanding customer base, which includes leading global companies like Spotify, Ramp, Vanta, and Brex. The recent introduction of Attack Score, a feature that utilizes machine learning to prioritize email threats, would further enhance the platform’s utility by providing security teams with a sophisticated tool to quickly assess and respond to potential breaches.
Jahanvi Sardana, a Partner at Index Ventures, lauded Sublime‘s innovative approach and go-to-market strategy, noting the substantial market opportunity for advanced email security solutions that engage security practitioners directly and promote community-based development.
