When something changes on your OT network, know what it means before it becomes a finding.
Industrial Defender turns internal network monitoring into a job you can get done:
• Establish what's normal
• Catch what isn't
• Decide what matters
• Prove you handled it right
Asset Context Prioritizes What Matters
Network visibility becomes more actionable when deviations are tied to asset criticality, risk, impact, anomaly type, and unknown or unauthorized devices.
Asset-centric, built into IDCM
Network anomalies are reviewed alongside the asset information, risk, events, baselines, and reporting workflows customers already use.
The full CIP-015 workflow, end to end
Monitor network activity, detect deviations, evaluate what needs action, and retain/protect the evidence needed to support compliance — not just pieces of it.
Define what must be monitored.
Establish expected network behavior.
Identify deviations from normal.
Turn anomalies into prioritized decisions.
Retain the complete record.
CIP-015 requires documented processes for risk-based network data feeds, anomaly detection, and anomaly evaluation — with anomalous network data retained until the associated action is complete, protected against unauthorized deletion or modification, and generally retained for three calendar years.
CIP-015 asks utilities to do more than watch traffic.
You need to define what should be monitored and why, notice when communication deviates from normal, decide whether that deviation is expected, benign, or a real problem, and keep a defensible record of how you handled it.
Most tools stop at detection. Analysts are left to manually chase down which asset this is, whether it's authorized, and whether it even matters.
That's hours per anomaly, multiplied across every substation and plant in your environment.
Network monitoring isn't the goal -- it's the input.
The real jobs are deciding what's worth attention and proving the decision was sound.
Industrial Defender builds all three into a single, asset-centric workflow inside IDCM, so your team isn't switching tools to get the job done.
Monitor What Actually Matters
Learn normal asset-to-asset communication across ports, protocols, and traffic patterns, so you have a real baseline instead of a guess.
Prioritize What's Worth an Analyst's Time
See every deviation next to the asset's criticality, risk score, and configuration history, so you triage by consequence, not by alert volume.
Prove it Was Handled Correctly
Retain the anomaly, the reviewer, the rationale, and the disposition, so audit season is an export, not a scramble. Engineered by the team with decades of experience streamlining compliance
Scope the assets and segments that need monitoring. Learn expected communication over a defined baseline period.
Detect new connections, unexpected ports or protocols, and unknown devices. Evaluate each deviation against asset criticality, configuration history, and vulnerability data to decide what it actually means.
Retain the complete, audit-ready record, from first detection through final disposition.
Five stages, one workflow, zero new tools to log into.
Network baselining is only as good as the visibility underneath it. Industrial Defender reaches Purdue Level 1 through native industrial protocols, so the baseline reflects what your assets are actually doing, not just what a span port happens to see.
Choose the collection method that fits each environment, and mix them across your fleet without changing how anomalies are reviewed or reported.
Passive Monitoring
Traditional network taps and span ports for continuous, non-intrusive traffic visibility.
Active Collection (IDC)
Agentless, protocol-native queries that reach devices passive monitoring alone can't see.
Agent
A persistent, sub-1% CPU footprint for the deepest asset-level detail, with a portable option for air-gapped assets.
Most network monitoring tools can tell you something changed.
Fewer can tell you whether that change is a problem worth your team's attention.
A new connection fires an alert. An analyst opens a second tool to identify the asset, a third to check its risk history, and a fourth to log the decision.
By the time it's resolved, the moment that mattered has passed, and the evidence trail lives in four different places that someone has to reassemble come audit time.
The same connection appears already linked to the asset's criticality, configuration history, and vulnerability status.
The analyst sees what changed and what it means in one screen, and the decision, along with the reviewer, timestamp, and rationale, is retained automatically as part of the same record.
Real utilities, real environments, real audit cycles.
