Industrial Cybersecurity Services help you protect automation environments. Our experts deliver IEC 62443-based Cybersecurity to safeguard productivity and uptime.

SCALANCE M Industrial Routers A versatile portfolio —wired or wireless: SCALANCE M includes mobile wireless routers and routers for wired communication.

Secure remote access for maintenance of distributed plants or machines is very easy with the VPN management platform SINEMA Remote Connect.

Industrial networks face constant cyber threats that can lead to production downtime, data loss, and safety risks. SCALANCE S Industrial Security Appliances provide robust protection by combining network segmentation, secure remote access, and seamless IT/OT integration within a Defense‑in‑Depth strategy.

With high-performance firewall and VPN capabilities, SCALANCE S enables precise control of communication between network zones while ensuring secure access across distributed industrial environments.

Reduce risks by dividing networks into secure zones and controlling communication with granular rules. Limit attack surfaces and protect production cells, lines, and plants from unauthorized access and lateral threat movement.

Support remote maintenance and monitoring with encrypted communication. Enable secure access to distributed assets while maintaining full control and visibility across multiple sites and users.

Connect industrial networks with IT systems while maintaining compliance with IEC 62443. Ensure consistent security policies and seamless data exchange across all organizational levels.

Process up to 750 Mbit/s firewall throughput with up to 1,000 rules and support up to 200 VPN connections. Enable secure segmentation and encrypted communication within a single integrated platform.

Ensure continuous operation with VRRP and firewall state synchronization. Maintain stable communication and seamless failover in case of device or network disruptions.

Configure via TIA Portal, web interface, or CLI and integrate into network management systems. Operate reliably in harsh environments with extended temperature ranges and rugged hardware design.

These features allow flexible integration into existing networks and secure communication across distributed industrial environments. SCALANCE SC-600 devices cover more complex architectures, while SCALANCE S615 provides an efficient solution for targeted protection and remote access.

SCALANCE S protects industrial networks by segmenting machines and production systems into secure zones and controlling communication between them. Only authorized access is permitted, preventing unauthorized users and reducing the risk of cyberattacks spreading across the network. It also supports use cases such as secure remote maintenance and flexible cell protection concepts within industrial environments.

SCALANCE S can be centrally managed and monitored using SINEC NMS, supporting network management aligned with IEC 62443 security standards. Devices can also be configured via TIA Portal, web-based management (WBM), or CLI, enabling flexible integration into existing IT and OT infrastructures. This allows seamless connection of industrial networks to enterprise IT security architectures while maintaining consistent security policies.

How a simple SCALANCE installation makes the Internet connection of large online live-events redundant and reliable – relieving the stress of everyone in the backstage area.
