How it works

From blind spots to proven compliance

  1. Discover

    Build one inventory from the records and tools you already have.

  2. Map

    Model zones, conduits and the flows that cross them.

  3. Assess

    Evaluate controls against the frameworks that apply to you.

  4. Prioritize

    Rate risks with operational context and agree treatment.

  5. Remediate

    Turn findings into owned, scheduled actions.

  6. Prove

    Show evidence and readiness to auditors and regulators.

Standards and regulations

Built for the regulations you face, wherever you operate

International standards and regional regulations across the EU, UK, USA and Middle East, assessed once and mapped to many.

EU law now sets binding cybersecurity duties for operators of essential services and for makers of connected products, implemented through national legislation in each member state.

  • NIS2Directive

    Risk-management measures, supply-chain security, management accountability and staged incident reporting (early warning within 24 hours). Applied through national laws such as Sweden's Cybersecurity Act.

  • CRARegulation

    Security-by-design and vulnerability handling for connected products. Vulnerability and incident reporting applies from 11 September 2026; most other obligations from December 2027.

  • NCCSRegulation

    Sector-specific rules for cybersecurity risk assessment and minimum and advanced controls for high- and critical-impact electricity entities.

  • CERDirective

    All-hazards resilience of critical entities, complementing NIS2's cyber focus.

  • Machinery RegulationRegulation

    Adds essential requirements on protection against corruption, including cyber, for machinery placed on the EU market. Applies from January 2027.

  • CLC/TS 50701Technical specification

Common questions

What is OTVista?

OTVista is an OT cybersecurity company offering a platform for OT asset visibility, risk and compliance management, together with professional OT security services.

Which standards does OTVista support?

International standards such as IEC 62443 and ISO/IEC 27001, plus regional requirements including NIS2 and the Cyber Resilience Act in the EU, the NIS Regulations and NCSC CAF in the UK, NIST CSF and NERC CIP in the USA, and NCA ECC and OTCC in Saudi Arabia.

Is the OTVista Platform available now?

The platform is in early access, with modules released progressively. Book a demo to see the current release and discuss which capabilities fit your environment.

How is OT cybersecurity different from IT security?

OT puts safety and availability first, runs equipment for decades, and often cannot be patched or rebooted on demand. Security has to be planned around production and engineering constraints.
