TECHWORLD ·
✦ AI Summary
Fortinet said it has obtained the highest-level Security Level 4 (SL4) certification under the industrial OT security standard IEC 62443-4-2 with FortiOS 7.6.
IEC 62443 is an international standard that defines cybersecurity levels for industrial control systems and OT environments in manufacturing, energy, power, transportation, and other sectors.
Fortinet said the certification demonstrates its OT security capabilities and will help improve ease of responding to regulations and procurement requirements.
As manufacturing continues its digital transformation, cyber risks targeting the sector are also rising. Against this backdrop, Fortinet announced on the 31st that it has obtained the highest level, Security Level 4 (SL4), under the international industrial OT security standard, IEC 62443-4-2. Fortinet said it achieved the SL4 rating with its FortiOS 7.6 operating system.
IEC 62443 is an international standard established by the IEC, the International Electrotechnical Commission. The standard defines cybersecurity levels for industrial control systems (IACS) and OT environments across manufacturing, energy, power, transportation, and other sectors. The IEC 62443-4-2 SL4 certification obtained by Fortinet represents the highest level in this standards framework.
SL4 refers to a level capable of defending against deliberate intrusion attempts by attackers with substantial resources and sophisticated technical capabilities. Fortinet said that by obtaining the IEC 62443-4-2 SL4 certification, it has demonstrated its OT security capabilities.
Fortinet said it has secured certification for both its development processes and its products within the IEC 62443 family. After obtaining IEC 62443-4-1 Maturity Level 2 (ML2) certification in February for its Secure Product Development Lifecycle (SPDL), the company said its FortiOS 7.6-equipped next-generation firewall (NGFW) product line has now passed IEC 62443-4-2 assessments across all areas.
The seven foundational requirements of IEC 62443-4-2 cover identification and authentication control, use control, system integrity, data confidentiality, restricted data flow, timely response to events, and resource availability. Of these, Fortinet met all 22 requirements in the identification and authentication control category and all 19 requirements in the system integrity category.
The certification applies to the FortiGate, FortiGate Rugged, FortiWiFi, and FortiGate VM product lines based on FortiOS 7.6 NGFW products. The company said that, following SPDL certification, it has now also completed product certification, and has finished verifying safety across the entire process from the design stage to the finished product.
Moon Kwi, executive vice president of Fortinet Korea, said that the IEC 62443-4-2 SL4 certification is the first case of its kind among cybersecurity vendors, describing it as the result of Fortinet's OT security capabilities being internationally recognized. He added that as cyber threats have become a real risk in domestic industries such as manufacturing, healthcare, energy, and transportation, the company will support local customers in adopting solutions with proven defense capabilities.
Fortinet said the certification is expected to make it easier for companies deploying solutions in industrial settings such as manufacturing, energy, transportation, and telecommunications to respond to regulations. It also expects the certification to improve the ability of companies adopting Fortinet products, including FortiGate, to meet procurement requirements.
Fortinet Korea plans to separately hold the OT Security Summit 2026 for domestic customers on November 11.
