In today’s world of increasing cyber threats, protecting industrial networks has never been more critical. That’s why Advantech has introduced the S1 Router series—a new generation of cellular routers designed with security at their core.

The S1 Routers are built to deliver enhanced protection for industrial applications that require compliance with key security standards, such as IEC 62443-4-2 SL1 and more. Thanks to features like secure boot and integrity checks, these routers ensure that your network infrastructure remains secure from unauthorized access or tampering.

Unlike standard routers, S1 Routers run on ICR-OS S1, a hardened Linux-based operating system with a dedicated firmware branch. This approach limits unnecessary flexibility in favor of greater security and system integrity, while still offering the convenience of web-based configuration.

Key benefits of S1 Routers:

    🔒 Certified security compliance for critical infrastructure
    🔒 Robust protection with secure boot, integrity checks, and hardened OS
    🔒 Regular security updates via a dedicated firmware branch
    🔒 Available on selected router models (look for “-S1” in the part number)

S1 Routers are an ideal choice for industries that need to meet strict security regulations or that operate in environments where cybersecurity resilience is non-negotiable. With continuous updates and proven compliance, they help future-proof your network while giving you confidence in your security posture.
