TL;DR: Nation-state activity against electric infrastructure can stay hidden long enough for attackers to map systems, escalate privileges, and prepare disruption, according to Crytica Security. OT operators need detection that shortens dwell time before hidden access becomes physical and operational impact.
Editorial analysis by NHI Mgmt Group, based on content published by Crytica Security: “The Grid Under Pressure: Why Electric Infrastructure Can’t Afford Delayed Detection”.
Key questions
Q: Why do traditional EDR tools struggle in OT environments?
A: Traditional EDR tools struggle in OT environments because many controllers, HMIs and embedded devices run unsupported operating systems, proprietary protocols, and fragile real-time processes that cannot tolerate aggressive scanning, isolation or agent installation.
Q: Why does delayed detection make critical infrastructure harder to defend?
A: Delayed detection gives attackers or faults more time to move from a local issue to a control-system or safety impact, especially where monitoring is sparse and response windows are short.
Q: How should teams detect compromise in constrained OT devices?
A: Use device-level integrity checks, because constrained OT devices often lack rich endpoint telemetry.
Practitioner guidance
- Instrument detection at the device layer Prioritise controls that observe activity inside or as close as possible to PLCs, controllers, and edge devices rather than relying only on network inference.
- Measure dwell time as an operational metric Track the interval between initial compromise and first reliable detection for each OT zone, then use that metric to rank sites and assets by exposure.
- Review exposed OT access paths Inventory internet-reachable industrial systems, remote access paths, and supplier connections that could give an attacker a foothold into operational networks.
Bottom line: Delayed detection is the core weakness the article identifies, because it lets intruders remain in OT environments long enough to prepare real operational harm.

Delayed detection is the control failure that matters most in electric infrastructure. The article is right to frame visibility latency as an operational risk rather than a narrow monitoring issue. In environments where physical processes keep running while defenders investigate, every extra hour of dwell time increases the chance of persistence, lateral movement, and coordinated disruption. Practitioners should treat time-to-detection as a resilience control, not a SOC metric.
A question worth separating out:
Q: What should operators do first when an OT intrusion is suspected?
A: First, operators should stabilise the process and preserve visibility by moving to a preplanned incident response playbook, isolating affected segments only where it will not endanger safety, and collecting logs, network captures and asset state. Then validate whether the intrusion is active, identify the affected controllers or hosts, and coordinate with operations, safety and security teams before making changes.
