The 10 OT Vulnerabilities Putting Your Plant at Risk
A practitioner's guide for OT/ICS security teams at mid-market manufacturers. Learn what attackers exploit first — and how to close the gaps before they do.
The 10 vulnerabilities we find in every OT assessment
The #1 cause of OT breaches. Factory defaults still active years after deployment.
No firewall, no DMZ — one compromised workstation touches your control network.
PLCs and HMIs running Windows XP/7 with no patch management process.
VPNs and RDP sessions with single-factor auth — the ransomware entry of choice.
Modbus, DNP3, and EtherNet/IP accessible without authentication or encryption.
Third-party contractors with standing remote access, no audit trail.
You can't protect what you can't see. Most plants can't enumerate their own devices.
PI/OSI historians bridging IT and OT — attackers love them.
IT playbooks don't map to OT. When things go down, teams improvise.
Unauthorized devices, rogue WiFi, and USB drives creating invisible attack paths.
