BlastShield Security Gateway delivers a unique combination of network cloaking, secure remote access, and software-defined microsegmentation, minimizing the attack surface, eliminating passwords, and enabling segmentation without network downtime. It is a natural evolution and replacement for the IT firewall and VPN solutions that evolve OT networks to Zero Trust. The BlastShield Security Gateway blocks the remote classes of risk identified by the MITRE ATT&CK framework, drastically altering the Return on Mitigation equation for OT networks and delivering the highest ROI by stopping most attacks before they can begin.
