SOLUTION EXAMPLESOT & Control Systems Security

OT & CONTROL SYSTEMS

As smart factories advance, cyber risks in manufacturing and OT environments are rising.
However, the need for continuous system availability and the reliance on legacy OSs make traditional security nearly impossible to deploy.
You need a robust defense that protects critical infrastructure
—without interrupting operations or adding overhead.

Key Challenges in OT Environments

  • Unpatchable Systems

    Vulnerabilities in Legacy OS

    System availability is the top priority in OT. Applying patches that require reboots or risk false positives is often impossible, leaving critical legacy systems exposed.

  • Air-Gap Risks

    External Intrusions

    The myth that "closed networks are safe" is dangerous. Threats easily bypass air gaps via USB drives and maintenance PCs, making traditional update-reliant security ineffective.

  • Resource Constraints

    High Administrative Overhead

    Production sites rarely have dedicated security teams. Conventional allowlisting requires constant, manual updates for every minor program change, creating an unsustainable management burden.

Solutions by AppGuard

  • Secure Legacy Assets

    Secure Legacy Assets

    Neutralize vulnerability exploits without relying on patches. By preventing unauthorized execution, we ensure continuous availability and safely extend the lifespan of your legacy OSs.

  • Low-Impact Defense

    Low-Impact Defense

    Protect closed networks and standalone environments without demanding system scans. Our lightweight solution ensures continuous production without degrading the performance of your control terminals.

  • Zero-Maintenance Security

    Zero-Maintenance Security

    With smart policy inheritance, redesigns are unnecessary even when updating programs. Maintain robust security without specialized IT personnel, drastically reducing operational costs.
