Vijil DART red-teams AI agents with adaptive attacks
Vijil has launched Diamond Adaptive Red Teaming for Agents (DART), an automated system that searches enterprise AI agents for security vulnerabilities and policy violations. DART does not fire a fixed list of prompts at its target. It deploys several adversarial agents of its own, which run multi-turn attacks and change their tactics as they learn.
The company says AI developers and application security engineers can use DART to uncover more problems across their agent fleets than they would find with red-team tools and services built on static test prompts.
The scale problem
Vijil points to a Gartner estimate as the reason for the launch. By 2028, the average global Fortune 500 company is expected to run more than 150,000 agents. In 2025 the figure was fewer than 15. AI engineering and governance teams lack the time and money to test that many agents by hand.
