Some legacy servers cannot host modern agents (EDR/AV) due to OS or application constraints, leaving them unprotected. MSPs need a way to gain visibility and block malware execution/transport without installing intrusive software on the host.
Why now: Stricter security needs for OT and improved inline scanning/inspection tech enable agentless protective sidecars to be practical for legacy environments.
A gateway or sidecar appliance deployed on the same subnet that provides agentless protections: SMB/RDP/HTTP proxying with on-the-fly file scanning, connection anomaly detection, remote command execution blocking heuristics, and integration with MSP RMM for alerts. MVP: transparent SMB/RDP proxy with file scanning and quarantine, simple anomaly alerts, and deployment playbooks for OT environments.
Built for: MSPs and on-premise IT teams managing legacy servers that can't run modern agents
Business model: subscription
Agentless Protection Gateway for Legacy Hosts targets a medium-sized market ($100M–$1B TAM). Existing solutions are incomplete or outdated — there's clear room for a better product.
