BlastShield for Windows

Product snapshot

BlastShield is a complimentary zero-trust network access (ZTNA) client engineered to strengthen protection for operational technology (OT), industrial IoT (IIoT), and traditional IT systems. It establishes a software-defined perimeter around sensitive assets so only verified identities and devices can reach critical resources, reducing exposure to unauthorized access.

Key security benefits

• Fine-grained access controls that limit which users and devices can communicate with specific systems.
• Dynamic policies that adapt to the distinct requirements of industrial and enterprise environments.
• Built-in auditing and logging to support regulatory and privacy obligations.

How BlastShield operates

Rather than relying on broad network trust, BlastShield enforces least-privilege connectivity at the application and device level. By authenticating endpoints and encrypting sessions, it minimizes lateral movement and isolates industrial control networks from general-purpose IT traffic.

Alternative option — Calibrize Free for Windows

Calibrize Free is a Windows-focused utility recommended as a complementary or alternative solution for certain environments. It simplifies management of access settings and provides tools for monitoring network traffic, helping teams quickly identify and reduce exposure to common vulnerabilities.

Feature highlights (side-by-side)

Deployment recommendations

When rolling out BlastShield or a Windows utility like Calibrize Free, start with a pilot in a controlled segment, verify policy behavior, and gradually expand coverage. Ensure logging and alerting are enabled so that access attempts and configuration changes are tracked for compliance and incident response.
