When the consequence is national, not commercial

Critical national infrastructure operators face the same adversaries as everyone else, plus a set that does not care about money. The estates are converged, long-lived and heavily regulated, and the failure mode is public. HexaShield brings one platform across IT and OT, with deployment models that respect sovereignty and segmentation.

Where we are brought in

Three problems we are asked to solve where downtime is the incident

For a grid, a network or a water system, availability is not an IT metric. These are the three situations operators bring to us most often, each one shaped by the fact that the safest change is frequently no change at all.

01

IT and OT are converging faster than the assurance around them

OT
The problem

Remote monitoring, analytics and vendor connectivity have joined operational systems to the corporate estate, site by site, over years. The connections are real and largely undocumented, and the teams either side of them report to different directors with different definitions of risk.

How HexaShield solves it

Operational Technology on HexaOT: one unified view from generation and control systems through to field and remote assets, passive and safe for continuous operations, feeding correlated OT telemetry straight into the HexaShield SOC for 24/7 detect and respond.

Operational TechnologyHexaOT
The business outcome

One estate picture that both the plant and the CISO recognise as theirs. Convergence stops being a category of unknown risk and becomes a mapped, monitored boundary that either side can reason about.

02

You cannot take the process down to secure the process

CTEM
The problem

Patch windows are measured in months and negotiated against operational commitments. Active scanning is not acceptable on a live control network. Standard enterprise security practice assumes a tolerance for disruption that this environment simply does not have.

How HexaShield solves it

Passive monitoring, vulnerability management, OT penetration testing and guided remediation in one platform, with HexaInt scoring which exposures actually matter to your estate, so limited outage windows are spent on what reduces risk rather than on clearing a CVE count.

Threat Exposure ManagementHexaIntHexaOTHexaStrike
The business outcome

Remediation effort is prioritised by consequence rather than by volume. Each outage window buys measurably more risk reduction, and security stops being the function that asks operations for time it cannot give.

03

Assurance has to satisfy a regulator, a board and a public

GRC
The problem

Reporting obligations, board scrutiny and public expectation all land on the same small team, and each audience wants a different depth of the same truth. Producing three versions of it by hand consumes the capacity that should be spent on the risk itself.

How HexaShield solves it

HexaView as the single client-facing console, role-based, so analysts get full case depth and the board gets a summary it can read, with HexaComply carrying the control, evidence and audit-room side as a managed service.

Governance, Risk & ComplianceHexaComplyHexaView
The business outcome

One truth at every altitude, exported on demand for leadership, auditors and insurers. Assurance becomes a by-product of running the service rather than a separate reporting exercise competing for the same people.

The expectations shaping assurance in your sector

NIS2 for in-scope essential and important entities · the NCSC Cyber Assessment Framework where it applies to your sector · sector regulator reporting duties · board and audit-committee assurance requirements.

We map the ones that apply to your jurisdiction, flag, licence or trade during onboarding rather than assuming them here. Compliance frameworks and regulatory requirements change over time; the specific frameworks in scope, and their current requirements, are confirmed and verified with your counsel during onboarding.

Threat landscape

What actually goes wrong in Critical National Infrastructure

Pre-positioning by state actors

Access is established and held quietly, without immediate action. Detection has to find dwell, not just damage.

IT-to-OT lateral movement

Corporate compromise is the usual route into the control network, via shared identity, jump hosts and vendor remote access.

Vendor and integrator remote access

The engineering support that keeps plant running is also a standing, high-privilege path in.

Unpatchable by design

Safety cases, vendor certification and continuous operation mean known vulnerabilities persist for years by necessity.

Hacktivism against exposed control systems

Internet-reachable HMIs and PLCs are found and interfered with by low-sophistication actors, repeatedly and publicly.

Assurance burden

CAF, NIS2 and sector regulators all demand evidence, and producing it competes with running the service.

One connected picture

Corporate and control networks, as one estate

Attackers move between IT and OT in minutes. Most defences are still organised as though the two were separate businesses, with separate tools, separate teams and no shared timeline. HexaCore gives them one.

Control networks SCADA, PLC, RTU, safety systems
Field & remote sites Dispersed, low bandwidth, unstaffed
Corporate IT Mail, identity, engineering workstations
Remote & vendor access Maintenance sessions, jump hosts
Physical & building systems Access, surveillance, environmental
Integrators & OEMs Supply chain and service providers

One converged timeline IT and OT events in the same picture

Sovereign deployment, 24/7 cover Where the data has to live

Discovery is passive and correlation happens in HexaCore, so bringing control networks into the picture does not mean putting traffic onto them. Deployment follows your segmentation, not the other way round.

Obligations

The regulatory picture

The frameworks and regimes that shape security programmes in this sector. HexaComply maps one control set across all of them.

NIS2

Essential and important entities across energy, transport, water, digital infrastructure and public administration.

UK NIS Regulations 2018

Obligations on operators of essential services and their competent authorities.

NCSC Cyber Assessment Framework (CAF)

The assessment model used across UK CNI and GovAssure.

IEC 62443

The reference standard for industrial automation and control system security.

NERC CIP

Mandatory for bulk electric system operators in North America.

ISO/IEC 27001 & ISO 22301

Information security and business continuity, commonly required alongside sector rules.

The approach

How HexaShield covers it

  1. 1One picture across IT and OT

    HexaOT and HexaSOC share HexaCore, so lateral movement between corporate and control networks is a single narrative rather than two teams comparing notes.

  2. 2Passive by default in the control network

    Discovery observes rather than probes, which is the only responsible posture where availability and safety outrank everything else.

  3. 3Nation-state relevant intelligence

    HexaInt tracks exposure specific to your organisation, including remote-access services, credentials and supplier compromise.

  4. 4Validated exposure under approval

    HexaStrike proves which vulnerabilities are genuinely reachable, with sensitive OT actions requiring explicit human approval.

  5. 5Sovereign deployment

    On-premises deployment keeps operational data inside your boundary, including for air-gapped and tightly segmented sites.

Integrated capabilities and proprietary platforms under one operating model, so there is no gap between the team that detects something and the team that answers for it.

No rip-and-replace

We sit above the stack you already run and take telemetry from any source. Nothing here depends on you replacing tooling you have already bought and trained people on.

Transparency by default

Whatever you buy feeds HexaView, the same truth our analysts see, at the depth each audience needs, exported on demand for leadership, auditors and insurers.

FAQ

Questions, answered

Can HexaShield be deployed entirely on-premises?
Yes. HexaOT deploys on-premises or in the cloud, and for air-gapped or tightly segmented sites it can run entirely within your boundary. This matters for CNI operators with data-residency, sovereignty or classification constraints that rule out a purely cloud-delivered service.
How do you detect pre-positioning rather than active attack?
By looking for dwell rather than damage. That means behavioural detection around identity, remote access and east-west movement, threat hunting as a standing activity rather than an incident response, and intelligence that tells you which techniques are currently being used against your sector. HexaSOC runs hunting agents continuously for exactly this reason.
What is the NCSC CAF and how does HexaShield help?
The Cyber Assessment Framework is the outcome-based model the UK NCSC publishes for assessing the cyber resilience of essential services, and it underpins GovAssure. It asks for evidenced outcomes rather than tick-box controls, which suits a platform that generates evidence by operating: HexaComply maps live evidence from detection, OT visibility, vulnerability management and testing onto CAF objectives.
Is active testing ever appropriate in CNI?
Only under tight control. HexaStrike operates within guardrails you define and approval-gates anything touching sensitive operational technology. The alternative, never testing OT because it is considered too fragile, leaves the highest-consequence systems the least understood, which is its own risk.
