IEC 62443 Industrial Cybersecurity Services

Prevent and combat industrial cyber-attacks with industrial cybersecurity solutions

Prevent and combat industrial cyber-attacks with industrial cybersecurity solutions

Industrial cybersecurity is a crucial area that deals with industrial information systems. It involves studying potential attacks and threats to industrial information, identifying gaps, devising and implementing industrial cybersecurity solutions and considerably mitigating risks. The entire ecosystem could be compromised, given the damage that an industrial cyber-attack can cause to the company's data, infrastructure, connected equipment. This makes industrial cybersecurity a critical aspect of any cyber-physical operation.



  • Enhance cyber resilience of your products and systems through a structured approach to industrial security

  • Display your commitment to cybersecurity with the globally renowned cybersecurity certifications

  • Demonstrate your security capabilities by implementing IEC 62443 standard requirements and industry best practices

WHAT IS IEC 62443 - industrial cybersecurity

Aiming to mitigate risk for industrial communication networks, the international IEC 62443 standards provide a structured approach to cybersecurity for all types of plants, facilities and systems across industries. These standards apply to component suppliers, system integrators and asset owners.

Through a set of defined process requirements, these standards ensure that all applicable security aspects are addressed in a structured manner throughout the stages of specification, integration, operation, maintenance and decommissioning. Furthermore, these standards foresee that processes are established to facilitate all necessary technical security functions. Adapted to the relevant project scope, IEC 62443 security levels lay the foundations for cybersecurity robustness throughout the product and system lifetime.

The implementation of industrial cybersecurity certification can also boost the competitiveness of the supplier and system integrator. A third-party IEC 62443 certification demonstrates to manufacturers, asset owners and operators that the component or system is in line with industry best practice for cybersecurity solution.


iec 62443 certification schemes

Suppliers, development teams and system integrators worldwide partner with us to confirm their compliance to applicable process/product/system requirements as laid out in the standards. TÜV SÜD provides IEC 62443 risk assessment, testing and evaluation to the IEC 62443 certification and certifies processes, products and systems under the following Certification Schemes:

  • ISASecure® IEC 62443 Conformance Certification

    The ISASecure Certification program is based on the Industrial Automation and Control security lifecycle as defined in IEC 62443 standards, with additional requirements published in the ISASecure Certification specifications. Depending on the type of certification, vulnerability assessment may have to be performed before certification is granted.

    TÜV SÜD PSB is an ISASecure Chartered Laboratory (License No. ISCI-CL0006) authorized by ISA Security Compliance Institute (ISCI), a not-for-profit automation controls industry consortium that manages the ISASecure conformance certification program.

    We offer 3 types of certification with four security assurance levels (SAL) in alignment with IEC 62443 standards.

    • ISASecure Component Security Assurance (CSA) Certification
    • ISASecure System Security Assurance (SSA) Certification
    • ISASecure Security Development Lifecycle Assurance (SDLA) Certification

    A company’s development process, component, or system that passes evaluation according to the latest version of ISASecure specifications will be granted with ISASecure certification by TÜV SÜD. The ISASecure Mark may be affixed on certified products and systems.

  • IECEE-CB Scheme for Industrial Cybersecurity

    IECEE Certificates of Conformity are issued for processes/products/systems based on a one-off evaluation in accordance with the rules of the IECEE-CB Scheme. No marks or logo of TÜV SÜD are allowed on a certified product.

    • Product Capability Assessment (IEC 62443-2-4 / IEC 62443-3-3 / IEC 62443-4-2)
    • Process Capability Assessment (IEC 62443-2-4 / IEC 62443-4-1)
    • Product Application of Capabilities Assessment (IEC 62443-4-1)
    • Solution Application of Capabilities Assessment (IEC 62443-2-4 / IEC 62443-3-3)
  • TÜV SÜD Product Service certification mark for Industrial Cybersecurity

    The IEC 62443 standards address security processes along the complete supply chain. TÜV SÜD mark provides certificates based on a set of security profiles from IEC 62443. Surveillance activities would be conducted to certificate owners to check if the compliance is maintained through the duration of certification.

    For product suppliers, TÜV SÜD provides industrial cybersecurity certification services based on IEC 62443-4-1. The standard applies to the supplier’s overall security programs, and to the security processes connected to the development of the relevant component or control system.

    Beside the generic process aspects during product development and system integration, the IEC 62443 standards specify technical security requirements to components and systems. These technical requirements are described in IEC 62443-4-2 and IEC 62443-3-3.



All staff involved in a modern industrial system now require at least basic IT and OT security knowledge in order to recognize security problems and not to endanger industrial operations through their behavior. The training increases the participants security awareness by communicating existing threats and current attack vectors. The IEC 62443 foundation course has been specially designed to enable industrial personnel to implement the most critical IT and OT security principles for a secure plant operation.

TÜV SÜD offers an IEC 62443 training programme tailored to industry needs. Through targeted industrial IT security training, you will be equipped with the necessary competency to design, maintain and operate your plants safely and in a secure way.
