Sublime Security, an AI-driven, configurable email security platform, has received $20 million in Series A investment AI to bolster its innovative protection strategies against email risks for businesses. The financing round was led by Index Ventures and saw participation from Decibel Partners and Slow Ventures, both of which were previous investors. The additional funding will be channeled towards expanding platform investments and enhancing custom experience.
The announcement of funding synchronizes with the activation of Dmitri Alperovitch as a member of Sublime’s Board of Directors. Alperovitch, a cybersecurity luminary, is a co-founder and former CTO of Crowdstrike. His appointment underlines a major endorsement of Sublime’s future direction and approach.
The 2023 FBI Internet Crime Report, which associates Business Email Compromise (BEC) schemes with losses exceeding $2.9 billion, underlines the continuous role of emails as primary vectors for cybersecurity threats in the realm of digital communication. Considering the ubiquitous underreporting, the actual magnitude of the losses could be much higher. Sublime Security, to address these problems, has developed a platform that offers immediate security right out of the box and a wide spectrum of customization options to meet unique organizational needs.
Setting itself apart from the usually opaque and one-size-fits-all solutions prevalent in the cybersecurity domain, Sublime offers an alternate way forward. It equips security teams with hunting tools for perceived threats, custom detections, and reduction of attack surface, all of which are scalable and transparent. With seamless integration with cloud email environments and facilitating free hosting, their technology enables a wide range of companies to access and utilize their core technology.
Sublime Security‘s founder and CEO, Josh Kamdjou, previously worked at the US Department of Defense in various cybersecurity roles and as a private sector red teamer. He commented on the dual-purpose nature of generative AI in both creating advanced cyber-attacks and strengthening defensive strategies through automatic detection and triage systems. Sublime’s platform takes advantage of this technology to provide better visibility and control, allowing companies to actively react to threats conveyed via email.
The open-source character of Sublime Security‘s Core Detections, which are accessible on GitHub, serves as an illustration of the company’s dedication to a community-led approach to cybersecurity. This strategy could democratize access to state-of-the-art security measures, as well as promote a cooperative culture where businesses can stay one step ahead of threats. Advanced users have the opportunity to further customize their security protocols using Sublime’s unique Message Query Language (MQL), which integrates with main email services like Microsoft 365 and Google Workspace.
Sublime’s rapidly growing customer base, including globally recognized companies like Spotify, Ramp, Vanta, and Brex, is a clear indication of its market traction. The recent debut of Attack Score, a feature using machine learning to rank email threats, is expected to enhance the platform’s value by supplying security teams with a refined tool designed to evaluate and react swiftly to potential breaches.
Jahanvi Sardana, a Partner at Index Ventures, spoke positively about Sublime‘s inventive method and market penetration strategy, highlighting the significant market potential for sophisticated email security solutions that engage security practitioners directly and encourage community-based development.
