ARIA Cybersecurity, a CSPi business, announced that a major US oil refiner has deployed its AZT PROTECT solution to protect critical OT infrastructure from attacks and production disruptions. The refiner was struggling to keep critical applications fully protected, avoid costly production outages, and manage legacy systems no longer receiving security updates from vendors.
Why it matters
The oil and gas industry is a critical part of the US economy, and protecting these vital facilities from cyber threats is essential. ARIA's solution helps address the unique challenges refiners face in securing legacy industrial control systems that are costly to upgrade but essential for continuous operations.
The details
ARIA's AZT PROTECT solution was selected because it provides an affordable, simple-to-deploy, and fully automated approach to locking down critical applications from unintended updates and stopping malware, ransomware, and other code-based attacks. The solution utilizes patented AI-based countermeasures to shield applications without requiring constant monitoring or updates from the internet, which can disrupt production.
