If you've sat through a vendor demo in the last six months, you've probably been told some version of the same story: CIP-015 is bearing down on you, the clock is ticking, and you need to deploy something — ideally what they're selling — right now or you'll be out of compliance.
It's a scary pitch.
It's also wrong.
NERC CIP-015-1 — the new Internal Network Security Monitoring (INSM) standard — is real, it's coming, and it's going to meaningfully change how high and medium impact BES Cyber Systems are monitored.
But the enforcement deadlines are years away, and the rush-to-deploy posture being marketed by some of our peers in the industry is going to leave utilities with the wrong tools, the wrong baselines, and the wrong assumptions baked into their OT environments.
Let's set the record straight on the timeline, the actual risk of rushing, and what responsible preparation looks like in 2026.
What CIP-015 actually requires, and when
CIP-015-1 was approved by FERC in 2024.
It establishes a new requirement for INSM [JW1] — visibility into east-west traffic inside the electronic security perimeter — for high impact BES Cyber Systems and for medium impact BES Cyber Systems with External Routable Connectivity.
The implementation timeline that NERC put in place gives Responsible Entities 36 months for high impact systems and 60 months for medium impact systems with ERC, measured from the standard's effective date.
In practical terms, that means enforcement falls somewhere in the 2028–2030 window depending on your impact rating.
That is not "right now."
That is not "next quarter."
That is multiple budget cycles, multiple maintenance windows, and multiple technology refresh opportunities away.
If a vendor is telling you that your audit posture in May 2026 depends on signing a contract this quarter, ask them to point at the specific date in the standard.
They can't, because it isn't there.
Why racing is worse than waiting
The FUD playbook works because compliance teams are conditioned to move early. But CIP-015 is a category of standard where moving early — without a clear strategy — is actively counterproductive.
Here's why:
1. INSM is outcome-based, not prescriptive. CIP-015-1 doesn't tell you what tool to buy or what protocol to inspect. It tells you to detect anomalous activity inside your trust zones and to retain the data needed to investigate. A point solution deployed in 2026 to a spec that doesn't yet exist in your environment may not be the same thing your auditor evaluates in 2029.
2. You can't monitor what you haven't baselined. Effective INSM depends on knowing what "normal" looks like in your OT network. Utilities that deploy detection tooling before they've established asset inventories, communication baselines, and protocol expectations end up with alert fatigue, false positives, and dashboards their SOC learns to ignore. That's not compliance — that's a liability.
3. OT is not IT. Industrial control system networks don't tolerate the deploy-fast-iterate-later cadence that works in enterprise IT. Sensors, taps, and collectors deployed without proper engineering review can introduce latency, instability, or — in the worst case — operational impact to the very systems you're trying to protect. The right pace for OT is the deliberate pace.
4. The market is going to mature. The detection tooling, the reference architectures, and the audit guidance for CIP-015 are all going to be substantially better in 2027 than they are in 2026. Utilities that lock in three-year contracts on first-generation INSM products today are going to be writing checks for those decisions when better options exist.
What you should be doing right now
None of this is a case for ignoring CIP-015. There is real work to do, and the work that pays off is upstream of detection technology:
What's coming from us
Industrial Defender is actively working on CIP-015. We're refining our approach to INSM in a way that fits how OT environments actually operate — and how our customers are actually going to be audited — not how vendor marketing wishes they would be.
We'll be sharing detailed guidance, reference architectures, and product direction over the next several months. When we do, it will be grounded in what the standard actually requires, what your auditors will actually look for, and what your operators will actually tolerate in production.
Until then: don't let anyone scare you into a bad decision. The clock is real, but it's not the alarm clock our competitors are selling.
If you'd like to talk through your CIP-015 readiness with our team, contact us — no urgency, no FUD, just a conversation.
