Industrial Cyber Security Certification

BYHON Entity Certificate
The declaration of conformity to IEC 62443 standards is the pinnacle to aim for to prove the security of an efficient infrastructure.

Obtain the State of Compliance

Our internal BYHON division is accredited by ISASecure® for the issuance of certification according to IEC 62443 schemes.

In the case of a specific installation at a plant, we perform third-party verification to issue a technical report and declaration of conformity. An assessment can be carried out for a new installation, for a revamp of an existing installation or for an infrastructure in use.

The purpose of the service is to perform an independent assessment that highlights the compliance of specific contract installations according to a specified level of security (SL-A) compliant with IEC 62443.

The State of Compliance is a valid and proven means of attesting that an OT configuration meets the parameters of security, integrity, availability and confidentiality, as per the ISA/IEC standard.


IT Cyber Security deals with Information Technology security, such as personal electronic devices and company networks; instead, OT Cyber Security is when the security is for Operations Technology, or industrial automation and control systems including PLCs, HMIs, and SCADA systems.

The most common and most perceivable consequences for a company struck by a cyber attack are related, for instance, to business continuity due to interrupted production after stopping the attacked systems. Threats can also entail altering or inhibiting safety functions on machinery and systems; for example, when automation is implemented by safety PLCs connected online. There is also the environmental risk, where dangerous emissions from systems under attack can cause, similarly to business continuity or safety of machinery issues, serious damage financially and to the company’s reputation.

The legislative references in the IEC 62443 standard directed at OT device users are found in IEC 62443-2-1 and IEC 62443-2-4 regarding maintenance requirements of systems in conformity with the standard by introducing cyber security policies and procedures.
