Keystrike is a remote access security solution that provides continuous cryptographic verification of physical user presence during remote sessions. The platform addresses credential compromise scenarios by ensuring that even when credentials are stolen, attackers cannot leverage them without physical presence. The solution operates on a sustained attestation model, providing ongoing cryptographic proof that commands originate from physically present, authorized users. This approach targets social engineering tactics that trick users into accepting remote desktop connections and detects when attackers inject themselves into active sessions. Keystrike offers multiple security capabilities including prevention of unauthorized remote access, detection of malicious activity within sessions, isolation of compromised workstations from sensitive systems, and automated response orchestration. The automated response features include account suspension, session revocation, and network access deactivation for compromised endpoints. The platform is designed for deployment across enterprise environments and operational technology (OT) systems. It integrates with existing infrastructure to block lateral movement and prevent attackers from executing commands within remote sessions, even after initial compromise has occurred. Keystrike positions itself as a frictionless security control that does not require user interaction or workflow changes while providing protection against advanced persistent threats and nation-state sponsored attacks targeting remote access infrastructure.
