Critical services in view

secnostic shows which facilities, IT/OT systems, networks, and suppliers keep your critical services running. Operations and security see dependencies, maintenance risks, vulnerabilities, and response paths, while proof for NIS2 and critical-infrastructure rules stays within reach.

For energy, water, wastewater, and municipal utilities.

See distributed sites, and prove it

Distributed sites and long-lived control systems turn visibility itself into the security task. NIS2 requires registration and risk management, the national critical-infrastructure act adds physical resilience, and proving attack detection depends on a current picture of every asset and conduit.

What this covers

In operations, the important question is not only whether an asset exists, but also which facility, service, remote access path, and change depend on it. OT asset inventory guidance and OT security guidance put that operational view of assets, network paths, and responsibilities at the center. For NIS2 and national critical-infrastructure legislation, it also becomes reliable evidence from operations.

Utilities manage distributed sites, long-lived OT, supplier access, and narrow maintenance windows. Without a shared picture, incidents, patches, and vendor advisories become slow, expensive, and risky.

Outcomes

  • faster root-cause work for incidents, advisories, and unexpected communication paths
  • better maintenance and patch planning because affected services, zones, and owners are visible
  • a clear order for vulnerabilities, EOL/EOS, spare parts, and measures by operational impact
  • less friction at handover between control room, IT, OT, suppliers, management, and internal audit
  • auditable proof for NIS2, critical-infrastructure rules, and internal audits straight from daily operations

What a blind spot in critical services costs

In an incident, what counts is how fast you know what is affected, who owns it, and what must be proven.

Unattended remote maintenance

Supplier and maintenance access is a main entry point when purpose, owner, and approval are not recorded.

Unknown dependencies

Which asset carries which service, and across which zone, often becomes clear only when it fails.

Missing attack detection

Without dependable logging and detection, the required attack-detection maturity for the proof is missing.

Evidence by hand

Otherwise the proof for section 8a, NIS2, and auditors is assembled from spreadsheets just before the deadline.

From signal to evidence

Four steps that turn day-to-day operations into dependable evidence, instead of hunting for it before the audit.

  1. See

    What runs at which site?

    The sensor and existing sources deliver assets, networks, and conduits across every site, passive-first with approval for active queries.

  2. Understand

    What does the critical service depend on?

    The graph links assets, zones, owners, and remote access, so dependencies and operational impact become visible.

  3. Detect

    Would an attack be noticed in time?

    Logging, detection, and response bring attack detection to the required maturity level, tied to real assets.

  4. Prove

    Is the proof ready for the auditor?

    The section 8a proof, the 24h and 72h reports, and the conduit register all come from the same current data.

In practice, following the obligations

Recurring critical-infrastructure obligations become clear workflows that meet the real deadlines.

  1. AnnounceA supplier requests a maintenance window for a facility at one site.
  2. Check conduitPurpose, owner, approval, and permitted paths of the access are in the model.
  3. WatchThe sensor observes which devices and connections appear during the window.
  4. ProveActivity and changes stay traceable after the window closes.

FAQ

Key questions before a first scoping conversation.

How does asset transparency help daily operations?

Operations teams see faster which facility, system, supplier, and communication path belongs to a critical service. Incidents, maintenance work, vendor advisories, and handovers require less searching and fewer assumptions.

Why is a classic asset list not enough?

A list shows individual systems, but rarely service context, communication paths, operational impact, maintenance windows, remote access, and ownership. Control room, IT, OT, and suppliers need that context.

How does secnostic reduce outage and response time?

secnostic connects observations, assets, zones, risks, owners, and measures. During an incident or advisory, teams can see which services are affected, who must decide, and which next steps are sensible.

Is evidence for NIS2 and critical infrastructure still covered?

Yes. Operational context creates evidence from daily work instead of from a separate text collection: scope, assets, risks, measures, exceptions, owners, and review dates stay traceably connected.

What is a sensible starting point?

Start small and close to operations: one critical service, one site, one recurring maintenance topic, or one concrete vulnerability situation. Data sources, gaps, and prioritized measures can then expand in a structured way.

Clarify the critical-infrastructure scope together

We start with one critical service, one site, or one concrete vulnerability situation and make the first data gaps visible.
