Palo Alto Networks makes AI-Powered OT Security easy to adopt. New Zero Trust OT Security solution secures critical infrastructure without additional sensors

Operational technology (OT) plays a significant role in the digital evolution process of companies in the industrial and manufacturing sectors, they monitor and control physical processes, such as production control systems, process automation, temperature, pressure and motion sensors, and industrial robotics. 

The usage and connectivity of operational technology (OT) are rapidly growing as are the number of cyberattacks on OT environments. These attacks can disrupt operations, causing damage that can reach far beyond revenue and reputation to the supply chain, human safety, and critical infrastructure. OT devices can be hard to secure because many lack built-in security and were not designed to be patched. 

In addition, high uptime requirements limit the ability to do regular security maintenance. OT environments are also at risk as organizations adopt new technologies like 5G, which enable mass connectivity, and open up remote access.

Zero Trust technology and security

Zero Trust technology is a network security strategy where no user or device on or off an organization’s network is granted access to connect to systems unless explicitly required.

According to the global survey “What’s Next in Cyber” by Unit 42, the research arm of Palo Alto Networks, for 29% and 28% of the IT leaders interviewed, the main benefit of a Zero Trust structure is the best adjustments that guarantee initiatives digital transformation and higher levels of overall security. The survey also revealed that among the challenges respondents face with regard to the Zero Trust framework is the lack of qualified vendors with a complete, integrated solution and the scarcity of tools for enterprise-wide deployment.

Industries such as manufacturing, energy, construction, agriculture, and supply chain are always in need of new solutions to keep up with changes in the market, which is why Palo Alto Networks introduces Zero Trust OT Security to better protect operational technology systems and devices. The new solution protects environments and industrial devices connected to 5G.

Most OT security solutions in the market fall short because they can’t identify all the assets and can only alert but don’t prevent threats. This leads to a patchwork of siloed security technologies, which can lead to security gaps,” said Anand Oswal, SVP, network security at Palo Alto Networks. Our OT Security solution is designed to help organizations stay secure through granular visibility and effective inline security while meeting their availability and uptime requirements.”

The new protection tool from Palo Alto Networks

Cybersecurity issues are often managed one issue at a time, resulting in security teams trying to protect companies with multiple security technologies siled, which can lead to security breaches. 

A key component of the solution is the new cloud-delivered Industrial OT Security service, which can be easily enabled — without the need to install additional sensors — by any of the 61,000+ active customers of Palo Alto Networks network security products: hardware and software Next-Generation Firewalls (NGFW) and Prisma SASE. Built on an AI-powered foundation with ease of deployment in mind, the new solution enables customers to secure their OT environments from the most sophisticated threats while simplifying their operations. 

Using the industry’s first ML-powered OT visibility engine, the Industrial OT Security service recognizes hundreds of unique OT device profiles, over 1,000 OT/Industrial Control System (ICS) applications, and has hundreds of distinct OT threat signatures to help protect these hard-to-secure assets. A notable feature of the service is its ability to help security teams proactively understand risk and apply controls. It continuously observes, categorizes and visualizes asset behavior so anomalies can be discovered immediately and addressed with firewall policy.

The Zero Trust OT Security solution secures multiple OT use cases with consistent Zero Trust policies, all managed centrally: 

• OT assets and networks using Palo Alto Networks NGFWs, along with the new Industrial OT Security service.
• Remote access using Prisma SASE.
• 5G-connected devices using NGFWs with Palo Alto Networks 5G-Native Security.

“As industrial OT systems and IT systems become more interconnected, so does the size of the attack surface available to the adversary. Defending against increasingly sophisticated threats requires expanded security strategies that can provide visibility, context, and Zero Trust capabilities across both OT and IT networks, devices, applications, and users,” said Dave Gruber, principal analyst, Enterprise Strategy Group. “The Palo Alto Networks solution embraces this unified security model, promising to help protect complex OT environments.” 

“Manufacturing has come into the crosshairs of many recent cyberattacks. Palo Alto Networks Industrial OT Security is a must have to ensure security best practices are in place,” said Jared Mendenhall, director, Information Security, Impossible Foods. “We look forward to Palo Alto Networks’ dedicated OT Security solution to help us further secure our manufacturing plant, remote operations, and realize our broader Zero Trust vision.” 

Availability

Palo Alto Networks Zero Trust OT Security solution and Industrial OT Security service will be available in March.
