VeilNet is a zero trust network platform designed for securing AI agentic systems. The platform enforces identity-based access control at the network layer, implementing workflow microsegmentation to restrict agent access to only required resources. The solution integrates at the code level through SDK function calls or as a deployed service, enabling agents to establish secure connections across clouds and networks without VPN configuration. It consolidates multiple networking functions including load balancer, ingress controller, proxy, and VPN into a unified platform. VeilNet authenticates agents through existing OAuth2 providers, eliminating the need for separate credential management or API key rotation. The platform automatically establishes direct connections between agents and resources, even across firewalls and different cloud providers. The network implements self-healing capabilities, automatically finding alternative paths when routes fail or nodes go down. It provides centralized control and visibility while using decentralized coordination for network optimization. VeilNet includes post-quantum cryptography for future-proof security compliance. The platform offers real-time monitoring of agent-to-resource connections through existing observability tools. Organizations can deploy VeilNet on their own infrastructure with no cloud dependency, maintaining complete control over data, nodes, and policies. Access control operates on a default-deny basis at the network layer, where administrators define simple rules specifying which agents can reach which resources.
