Cybersecurity for industrial control systems
IEC 62443 Compliance
Industrial control systems are the backbone of critical infrastructure. IEC 62443 sets clear OT cybersecurity requirements for operators and manufacturers. The Endian Secure Digital Platform helps you meet them in practice. With end-to-end network segmentation, central access management and European data sovereignty.
What does IEC 62443 require?
Network Security
Reliable protection for OT networks
Industrial networks connect machines, control systems and IT infrastructure. Attacks on these connections can halt production or put people at risk. Endian secures OT networks with UTM features, firewall, VPN and intrusion detection. This meets the baseline requirements of IEC 62443-3-3.
Access Control
Only authorized users gain access
Good access management is at the heart of OT security. The Endian Switchboard controls access by role and grants granular permissions. Each person and device gets only the access they truly need. This matches IEC 62443-3-3 and forms the basis for a zero trust model.
Network Segmentation
Zones and conduits per IEC 62443
IEC 62443-3-2 requires industrial networks to be divided into security zones. Endian 4i Security Gateways put these zones into practice. Critical components are isolated, lateral movement is blocked and traffic between zones is controlled.
Encryption
Secure data in transit
Data can be intercepted or manipulated in transit. Endian protects communication between IT and OT with encrypted protocols and secure VPN connections. This meets the IEC 62443-3-3 requirements for secure data transfer and protects sensitive production and control data.
Supply Chain Security
Control third-party risks
Maintenance providers, machine builders and system integrators often need access to your plants. Uncontrolled remote access is a serious risk. The Endian Switchboard enables time-limited, logged remote access based on zero trust. Every session is authenticated, authorized and recorded.
Digital Sovereignty
You decide where your data lives
Digital sovereignty means you decide where your data lives and who can access it. Endian is based in Bozen/Bolzano, South Tyrol, and develops its products in Europe. The Secure Digital Platform runs fully on-premises, with no dependency on external cloud services. For critical infrastructure, that is a basic requirement.

Answers to the most important questions
Frequently asked questions about IEC 62443
What is IEC 62443 and who does it apply to?
IEC 62443 is an international series of standards for the cybersecurity of industrial automation and control systems (IACS). It applies to operators, system integrators and component manufacturers, and defines requirements for security zones, access control, data communication and system integrity.
How does Endian support IEC 62443 compliance?
Endian provides technical solutions that cover core IEC 62443 requirements: network segmentation with 4i Security Gateways, access management through the Endian Switchboard, encrypted communication and continuous monitoring. Endian does not offer consulting or certification.
What is the difference between IEC 62443 and NIS2?
IEC 62443 is a technical standard with concrete requirements for OT systems. NIS2 is an EU directive that mandates organizational and technical measures for critical entities. The two complement each other: implementing IEC 62443 also meets key technical requirements of NIS2.
Can the Endian platform be operated without cloud connectivity?
Yes. The Secure Digital Platform can run fully on-premises. There is no dependency on external cloud services. This is especially relevant for operators of critical infrastructure with strict data sovereignty and network separation requirements.
Which Endian products do I need for IEC 62443?
For technical implementation you combine Endian 4i Security Gateways for segmentation and the Endian Switchboard for access management and secure remote access. Everything is managed centrally through the Secure Digital Platform.
Conclusion
With the Endian Secure Digital Platform, companies meet the technical requirements of IEC 62443 systematically and build a secure, resilient OT infrastructure. Network segmentation, access control, encryption and central monitoring cover the essential technical measures of the standard. For a full overview, see our whitepaper.
