IEC 62443 consulting:
Secure OT starts with a clear strategy

IEC 62443 defines the global standard for cyber security in OT and industrial automation systems. We help you to implement the requirements in practice and strengthen your OT security in the long term.

Why IEC 62443 is now indispensable

Digital production, networked machines and modern automation systems increase efficiency, but also the attack surface.
IEC 62443 provides a structured framework for ensuring OT security in a traceable and permanent manner.

The standard addresses safety:

  • Of production systems
  • Of control and automation systems
  • Machines and components
  • Networks and communicating systems

It is increasingly demanded by end customers, suppliers and operators - especially in regulated and critical industries such as rail (TS 50701), energy, pharmaceuticals, chemicals and automotive.

This creates a clear reality for companies:

Demonstrable IEC 62443 compliance is becoming a competitive advantage.

IEC 62443 GAP ANALYSIS REQUEST

What does IEC 62443 actually regulate?

IEC 62443 describes how industrial systems are secured over their entire life cycle. With security levels (SL 0-4) and the zones & conduits model, you can secure systems holistically. The central components are

Structured risk analyses

Security requirements for OT, networks and system architectures

Secure development processes

Organizational roles and responsibilities

Implementation of technical protective measures

Review and continuous improvement

Our services for IEC 62443

The standard does not describe a one-off project, but an end-to-end safety program that systematically combines technology, processes and organization. We support companies in all phases of implementation: from the initial assessment to the introduction of safe processes and technical measures.

IEC 62443 maturity and gap analysis

Assessment of your current security level in accordance with IEC 62443-2-1, 3-3, 4-1 and 4-2. You receive a clear analysis of which requirements are already fulfilled, which gaps exist and which steps make sense.

OT security concept and roadmap

Development of a complete security concept, including zone and conduit, architecture and technical and organizational measures. The result is a realistic, implementable roadmap for your OT security.

Secure Development according to IEC 62443-4-1

Introduction of secure development processes:We support you in integrating secure product development into your organization.

Security risk analysis according to IEC 62443-3-2

Standard-compliant risk analyses according to IEC 62443 3-2for plants and systems. We consider system structures, possible threats and specific vulnerabilities in the respective context.

Consulting, implementation and technical hardening measures

Implementation of effective countermeasures such as

  • Network segmentation
  • monitoring
  • access control
  • patch management
  • Logging and monitoring
  • Physical protection

We support you from planning to technical implementation.

How SECIRA supports the requirements of IEC 62443

IEC 62443 requires structured risk analyses, clear derivation of measures and continuous evaluation of the risk situation. SECIRA supports these requirements in that the tool:

  • clearly mapping complex industrial systems
  • analyzing risks in a comprehensible manner
  • evaluating weak points in terms of accessibility and exploitability
  • documenting measures, changes and assessments in a structured manner

FAQ - Frequently asked questions

For whom is an IEC 62443 consultation really worthwhile?

For companies with networked machines, systems or automation systems where OT security is business-critical or is increasingly required. Especially when customers or operators expect concrete proof.

What are the specific benefits of an IEC 62443 gap analysis?

It creates a reliable starting point. You then know where you stand, which requirements are relevant and which steps are realistically sensible without having to start a major project straight away.

Do existing systems have to be completely adapted?

No. In practice, measures are prioritized and implemented step by step. The aim is to reduce risks without unnecessarily affecting ongoing operations.

Where does it make sense to start implementing IEC 62443?

Not with technology, but with transparency. Only when system structures, risks and dependencies are clear can technical and organizational measures be derived in a targeted manner.

What role does SECIRA play in the IEC 62443 context?

SECIRA supports the structured recording and evaluation of risks and measures in industrial systems. It facilitates an overview and traceability, but is no substitute for professional classification or advice.
