Network Critical Testimonials.jpg


“Continuous monitoring is critical to digitization and automation of our many monitoring systems. Being able to monitor remote sites from a single location keeps our systems up to date without having a large staff running around in trucks.”


Senior Project Manager, Refining Operations


“In addition to monitoring control systems, we have security tools that understand our traffic patterns and look for anomalies that might signal malware or viruses attempting to embed in our systems. Unauthorized manipulation of our monitoring systems can have serious safety and production consequences. Network Critical TAP’s help us manage security without impacting network traffic.”
