Frontier AI Security Testing and Threat Simulation Lab

Irregular, founded in 2023 as Pattern Labs, was propelled by an extraordinary $80 million Series A in September 2025, making it one of the most heavily funded entrants in the emerging AI security space. Backed by a high-profile investor group, including Sequoia Capital, Redpoint Ventures, Swish Ventures, and prominent cybersecurity leader Assaf Rappaport, CEO of Wiz.

Irregular is positioning itself to rethink how modern organizations secure distributed AI infrastructure. While full public details about its platform remain limited, Irregular’s mission centers on safeguarding the sprawling, cloud-native environments that power today’s generative and agentic AI systems. The company focuses on securing “irregular” infrastructure — that is, the rapidly shifting, ephemeral compute landscapes created by on-demand GPUs, dynamic model hosting, multi-provider inference endpoints, and continuously morphing data pipelines. These environments defy traditional security tools, which expect predictable networks and static assets.

Irregular’s approach appears tailored for this new reality. The company is believed to be building a platform that continuously maps and monitors AI-driven infrastructure, detects anomalous behaviors and misconfigurations unique to high-performance compute environments, and provides automated guardrails to prevent exploitation. Its early emphasis is on issues like unauthorized model deployment, GPU cluster compromise, covert data exfiltration, and abuse of inference APIs — risks that are quickly becoming central to enterprise AI adoption.

With one of the largest early funding rounds in the AI security category, Irregular has the capital, talent pipeline, and investor backing to become a defining player in securing the next generation of AI infrastructure.
