Continuous Threat Exposure Management Purpose-Built for OT & ICS
Operational technology environments demand security that understands industrial protocols, respects safety boundaries, and never disrupts production. Piscium delivers attacker-side visibility across your entire OT estate, from enterprise IT to Level 0 field devices.
Why Traditional Security Falls Short in OT
IT security tools weren't designed for operational technology. The consequences of getting it wrong aren't data breaches. They're physical safety incidents, production shutdowns, and regulatory enforcement.
Blind Spots in OT Networks
Traditional IT scanners can't see, or safely probe, PLCs, RTUs, SCADA systems, and engineering workstations. Active scanning risks triggering safety shutdowns. You can't protect what you can't see.
Point-in-Time Assessments Expire Fast
Annual penetration tests and quarterly vulnerability scans produce snapshots that are outdated within days as firmware updates, configuration changes, and new connections shift your OT attack surface.
IT/OT Convergence Widens the Attack Surface
As IT and OT networks converge through historians, remote access, and cloud connectivity, attackers can pivot from corporate IT into industrial control systems through lateral movement paths that cross Purdue Model boundaries.
Risk Claims Without Evidence
Boards and regulators want proof of continuous risk management, but manual evidence-gathering is slow and error-prone. Point-in-time self-assessments don't reflect real, validated exposure.
Three Phases of Continuous Threat Exposure Management
Piscium's CTEM engine maps, prioritizes, and validates exposures across your OT environment: continuously, safely, and without disrupting production.
Passive-First Discovery for OT Environments
Piscium discovers and classifies every asset on your OT network using passive traffic analysis and protocol-aware fingerprinting. No packets are ever sent to production controllers unless you explicitly authorize active probing.
- Passive network monitoring identifies PLCs, RTUs, HMIs, SCADA servers, and engineering workstations
- Protocol-aware fingerprinting for Modbus/TCP, EtherNet/IP, OPC UA, DNP3, S7comm, PROFINET
- Automatic Purdue Model classification maps devices to their network zone
- Identifies shadow OT assets and unauthorized connections between IT and OT zones

Impact-Based Prioritization for Industrial Risk
Not every vulnerability is exploitable, and not every exploit has the same consequences. Piscium's attack graph engine scores OT exposures by exploitability, lateral movement potential, and operational impact, so you fix what actually puts production at risk.
- Attack paths scored by blast radius: safety system compromise, production shutdown, data exfiltration
- Purdue Model-aware prioritization: Level 0-1 exposures rank higher than Level 4-5
- Exploitability assessment considers OT-specific factors (firmware age, protocol weaknesses, segmentation gaps)
- Integration with your CMDB/asset inventory for context-enriched risk scoring

OT-Safe Validation That Proves Remediation
Piscium validates that remediations actually break attacker paths using safe, controlled emulations that respect configurable OT safety boundaries. No guesswork, just evidence-based proof that your fixes work.
- Autonomous AI agents emulate attacker techniques using OT-safe methods
- Configurable safety boundaries prevent actions that could affect production operations
- Pass/fail validation with evidence: screenshots, packet captures, audit trail
- Continuous re-validation ensures new configurations don't reintroduce broken paths

Built to a Standard for Autonomous Testing
Piscium's autonomous discovery and validation follow the OWASP Autonomous Penetration Testing Standard (APTS), operating safely, transparently, and within the boundaries you define. We don't issue regulatory attestations or claim certifications we haven't earned.
Built for OT/ICS From the Ground Up
- Purpose-built for OT/ICS, not IT security bolted onto industrial networks
- Passive-first discovery: zero production impact, zero safety risk
- Validated by autonomous AI agents with configurable OT safety boundaries
- Autonomous testing aligned with the OWASP APTS
- Deployed in energy, water, manufacturing, and transportation environments

Regional Water Authority Achieves Continuous OT Security Validation
A regional water treatment authority operating 6 treatment plants and 200+ pumping stations had no visibility into OT-specific attack vectors. Their IT-focused security tools couldn't understand industrial protocols, leaving PLCs and HMIs in a monitoring blind spot.
