About Manifold Security
Manifold Security provides an AI Detection and Response (AIDR) platform focused on securing autonomous AI agents operating on enterprise endpoints. Founded in 2025 by CEO Neal Swaelens, CTO Oleksandr Yaremchuk, and CRO Michael McKenna, the San Diego-based company addresses security risks associated with the increasing use of agentic AI. The founding team possesses deep expertise in AI security; Swaelens and Yaremchuk previously co-founded Laiyer AI, where they created LLM Guard, a widely adopted open-source LLM firewall. They joined with McKenna after Laiyer AI's acquisition by Protect AI (which was later acquired by Palo Alto Networks), identifying a gap in first-generation AI security tools that were not designed to handle autonomous agents that execute actions rather than simply generate text.
Read full description
The company's core product is its AIDR platform, which offers runtime visibility into the behavior of AI agents. It provides security teams with real-time maps of agent activities, including the tools they use, systems they access, and actions they perform. The platform is designed to detect anomalies and flag risks such as unauthorized system access or improper data exposure, allowing security teams to quarantine, remediate, or terminate rogue agents. Manifold's solution deploys on existing infrastructure without requiring new gateways or proxies, aiming for a low-friction implementation. The business model targets enterprises, particularly those with development and engineering teams that heavily utilize coding agents and are expanding their use of agentic AI across the workforce.
In March 2026, Manifold Security announced it had raised $8 million in a seed funding round. The round was led by Costanoa Ventures with participation from Cherry Ventures, Rain Capital, Modern Technical Fund, and notable angel investors. The capital is intended to fuel the continued development of its AIDR platform as the adoption of autonomous AI agents by developers and knowledge workers continues to grow.
