Build a Cybersecurity Shield for Your Critical Applications

Secure Boot

Secure boot ensures industrial devices start only with manufacturer-signed, trusted software, protecting system integrity and shielding critical infrastructure from tampering and cyber threats.

Virtual Private Network (VPN)

A reliable VPN establishes a fully encrypted network, safeguarding industrial data and communications from unauthorized access.

Deep Packet Inspection (DPI)

Deep Packet Inspection (DPI) analyzes network traffic to permit only authorized communication patterns, automatically blocking unauthorized attempts like unexpected remote connections to industrial devices.

Firewall and Network Address Translation (NAT)

A firewall with integrated DDoS protection monitors IPs, protocols, and network traffic patterns to block potential threats, while NAT simplifies network management by concealing private addresses and reducing the need for public IPv4 exposure.
