NOMINATION HIGHLIGHTS

Sublime Security is revolutionizing email security at a time when phishing schemes and social engineering attacks are escalating in both frequency and sophistication. The company was founded by Josh Kamdjou, a former DoD white hat hacker, and tackles a critical vulnerability in traditional email security: the industry’s legacy “black box” approach that leaves organizations dangerously exposed to emerging threats.

Legacy gateways and one-size-fits-all AI solutions employ a one-size-fits-all strategy with static rules and vendor-controlled coverage updates that are too slow to address evolving attacks. Sublime shatters this model with its proprietary Distributed Detection Model (DDM), which tailors defenses to each organization’s unique risk profile. Rather than relying on rules that quickly become obsolete, Sublime’s platform continuously learns and adapts, pulling insights from both its customer base and an in-house research team that actively hunts emerging threats in real-time.

At the heart of Sublime’s innovation are two industry-first AI agents. The Autonomous Security Analyst (ASA) provides end-to-end automation for triaging and responding to user-reported emails, while the Autonomous Detection Engineer (ADÉ) continuously adapts detection coverage. This multi-agent system enables Sublime to autonomously generate protection against new attacks within hours, not weeks or months, eliminating critical gaps that put organizations at risk. Crucially, these agents maintain explainability for analysts of all experience levels, ensuring human oversight remains simple and effective.

The impact speaks for itself. Leading cloud data platform and customer Snowflake achieved a 100% success rate blocking attacks after implementing Sublime. Fintech company Brex’s CISO Mark Hillick said that “with Sublime, we now have transparency and the confidence to keep up with emerging threats.” CrowdStrike co-founder Dmitri Alperovitch said the company is “taking a novel approach to disrupt the email security market, a space that is long overdue for a disruption.”

Sublime’s growth validates its approach. They closed a $150M Series C funding round in October 2025, shortly following its $60M Series B in December 2024. The customer base has doubled in size over the past year, with 100% growth in ARR in the first half of 2025, and a 100% retention rate of its enterprise customers since inception, including notable clients like Spotify, Snowflake, Zscaler, Anduril, Elastic, and SentinelOne.

In a marketplace dominated by legacy solutions, Sublime represents the future of email security: transparent and adaptive. By transforming security response times and delivering measurable results, Sublime is setting a new standard for protecting organizations against sophisticated cyber threats.
