OTDefend is an all-in-one security platform for industrial control systems (ICS) and operational technology (OT) — full visibility, proactive threat detection and vulnerability management, purpose-built for the most demanding environments.
OTDefend learns each device passively and opens it to a full profile: a computed risk score, communication peers, behaviour profile, open services, matched vulnerabilities and a live event history — nothing is hand-entered.
CVE exposure × severity × Purdue criticality × zone violations, so you prioritize what truly matters.
Direction, protocols and bytes for every conversation — clickable to pivot across the network.
Passive firmware/serial extraction drives firmware-sensitive CVE matching.
Off by default — a read-only identity probe (Modbus FC43, EtherNet/IP List Identity), rate-limited and fully audited, when you want to confirm a device.
Units behind a serial gateway (Modbus RTU over TCP) surface as individual devices, each with its own station ID and behaviour.

Every module shares one passive data pipeline, so the whole platform stays consistent — and safe on live process networks.
Automatically discover and manage every industrial device — without disrupting operations.
Detect and prioritize vulnerabilities in control systems without ever touching production.
Visual maps of your industrial network reveal connections and segmentation boundaries.
Monitor, audit and control every communication session in your OT environment.
Catch abnormal activity and threats in industrial networks with low false-alarm rates.
Analyze industrial protocols in depth to detect violations and potential attacks.
An offline AI analyst that explains alarms and recommends OT-safe responses — with zero data egress.
Physics-aware limits that catch protocol-valid but physically dangerous commands — the TRITON / Stuxnet class.
Prove detection works: inject famous OT attacks into an isolated engine and watch real alarms fire on the live stream.
Control-mapped and graded against your live configuration. FR1–FR7 and Security Level (SL) reporting, exportable to PDF.
OTDefend doesn't stop at visibility. It models your zones and conduits live, grades you against the standards that matter, and — when authorized — drives containment on your existing firewalls and EDR.
Live zone & conduit policy with per-framework, audit-ready PDF reports.
One "Contain" action blocks an attacker IP at every firewall and isolates victim hosts on your EDR — explicit and reversible.
Syslog/CEF and webhook outputs, plus ServiceNow and Jira ticketing from any alert.
A single PDF binder backs every control with live evidence — and a policy engine proposes zones, conduits and an allowed-comms matrix from observed traffic.
See every module working together on a network like yours — discovery, mapping, detection and response in one passive platform.
