Sublime Security, an adaptive AI-powered email security platform, has introduced the Autonomous Detection Engineer (ADÉ), a groundbreaking end-to-end AI agent designed to transform attack telemetry into transparent, auditable protection that security teams can trust.
With the rapid evolution of email threats fueled by generative AI, attackers are creating targeted, fast-moving campaigns that traditional solutions struggle to counter. Unlike conventional platforms that depend on vendor-issued updates, ADÉ autonomously analyzes attack patterns, writes and tests new detections, and validates tailored protections. By leveraging historical data at scale and refining detection strategies, ADÉ reduces detection timelines from weeks to hours while ensuring high accuracy.
“A key problem organizations face is the speed at which their defensive solutions can adapt and respond,” said Josh Kamdjou, Founder and CEO of Sublime Security. “With ADÉ, we’re now offering a team of AI Agents that autonomously generate clear, evolving protections against new attacks within hours, not weeks. Together with ASA, Sublime’s Autonomous Security Analyst, ADÉ provides enterprises with defenses that adapt as quickly as attackers, while preserving the visibility and control that matter most.”

ADÉ operates as part of a multi-agent system within Sublime’s platform, built around four core functions that keep human analysts informed and in control:
-
Deep Analysis: ASA triages suspicious or user-reported emails, producing behavioral analysis based on attacker Tactics, Techniques, and Procedures (TTPs).
-
Detection Engineering: ADÉ converts ASA’s findings into deterministic, behavioral detections powered by Sublime’s proprietary Message Query Language (MQL).
-
Smart Refinement and Validation: Before deployment, ADÉ backtests proposals against historical data to validate precision, minimize false positives, and confirm past attack prevention.
-
Human Approval: Security teams maintain oversight by reviewing and approving ADÉ’s recommendations with full transparency into its logic.
Engineered for explainability, ADÉ not only strengthens enterprise defenses but also provides valuable learning opportunities for analysts. It generates clear detection summaries as attacker techniques evolve, and its closed-loop system continuously adapts protections to specific environments avoiding one-size-fits-all security updates.
“What’s compelling about ADÉ is the shift from static defenses to a system that actively improves our specific coverage,” said Roger Allen, Senior Director, Global Head of Detection and Response at Sprinklr. “The promise of an agent continuously tailoring and backtesting new protections for our environment is a force multiplier. It means our defenses don’t just work, they evolve we get the benefit without having to do the work.”
The launch of ADÉ marks another milestone in Sublime Security’s rapid growth. The company secured a $60 million Series B funding round in December 2024 and earlier this year introduced ASA, its first AI agent, which automates the triage and remediation of user-reported emails.
