The new ruggedized firewall and the deep coverage of 5G-connected devices stand out in helping customers with comprehensive visibility and security across OT environments, and throughout their digital transformation journeys.”

Rugged Performance for Harsh Industrial Environments with the New PA-450R NGFW

Industrial customers need solutions for OT network security that are purpose-built and reliable in environments where exposure to wide temperature ranges or dusty conditions is common. This new ruggedized NGFW extends our Palo Alto Networks best-in-class security to organizations’ harshest operational environments.

Designed for OT environments, like power substations, the PA-450R is a new ruggedized, ML-based Next-Generation Firewall (NGFW). It delivers up to 3X the performance of our previous generation of ruggedized firewalls, and is the fastest-in-class ruggedized firewall available today. It also has fail-to-wire capabilities that support seamless data pass-through during power failures to the NGFW, enabling continuous operations.

The PA-450R natively integrates with Industrial OT Security, bringing visibility, security, continuous trust verification and ongoing threat prevention together in one platform. With the PA-450R and Industrial OT Security, OT network safety and integrity are supported from a single, robust system that can withstand the harshest conditions to secure industrial environments.

Industry-Leading Asset Identification and Risk Visibility for 5G Connected Devices

5G connectivity within OT environments holds immense potential for operational efficiencies, but often lacks adequate security controls to mitigate cybersecurity risks. Palo Alto Networks provides the industry's first and only 5G security solution designed to comprehensively safeguard industrial operations with enterprise-grade security.

Augmenting Palo Alto Networks 5G-native security capabilities with Industrial OT Security, this solution delivers extensive visibility and protection for every cellular connected device, regardless of its network connection. It also supports other mobile-connected devices, including 4G/LTE and 3G.

Working seamlessly within the Palo Alto Networks NGFW, this solution offers customers the ability to correlate mobile-specific contexts, including IMEI and IMSI, with high-fidelity device identification, such as device type, vendor make, model, operating system and risk and behavior analytics. We’ve also enhanced the Industrial OT Security’s device database by incorporating an additional 220,000 device types, sourced from the GSMA database.

This unparalleled level of visibility empowers customers to enhance their operational technology asset management, assess risks, detect anomalies, and swiftly respond to threats. For instance, should a mobile device unexpectedly establish communication with an application (such as a file transfer) that typically isn't linked to its device category, the NGFW can promptly generate an alert. It will then recommend security policy adjustments to enforce, which leverage the capabilities of machine learning to proactively thwart real-time threats. This seamless integration offers a holistic security solution tailored for 5G and mobile connected devices in OT environments.

Risk-Based Vulnerability Management for Mission-Critical OT Environments

OT environments are often mission critical with high uptime requirements, significantly influencing which vulnerabilities to patch and when to patch them to avoid operational disruption, loss of revenue or unnecessary safety risks.

To help security teams reduce business risk by focusing on what matters the most, we are pleased to introduce a risk-priority classification feature within Industrial OT Security, based on a multifactor risk assessment. To identify vulnerabilities that pose the greatest risk, Industrial OT Security looks beyond CVSS, evaluating threat likelihood indicators and the impact to a customer’s organization should their assets be compromised.

With virtual patching capabilities, Industrial OT Security offers a critical advantage for enhanced threat protection in OT environments. It prevents cyberattacks from exploiting known vulnerabilities while awaiting a maintenance window for potential patching. This capability empowers security teams in OT environments to maintain the stability and reliability of OT systems while significantly bolstering cybersecurity defenses.

Improved Management Flexibility and Resiliency for OT Environments with the SD-WAN On-Premise Controller

Digital transformation is driving geographically dispersed OT assets, like power grids and oil fields, to establish stronger connections for centralized control. Organizations must meet stringent reliability and performance requirements, ensuring uninterrupted operations even in the event of internet outages. Software-defined wide area networking (SD-WAN) provides simplified, secure networking that surpasses traditional site-to-site VPNs. Businesses want the benefits of adopting SD-WAN in OT environments but also want to avoid introducing the additional risks of a direct connection to the internet.

Now the Prisma SD-WAN on-premise controller (OPC) brings next-generation secure, industrial SD-WAN management on-premises, so OT asset owners and operators can modernize their networks securely and confidently. With the SD-WAN OPC, end-to-end SD-WAN capabilities are offered on-premises, delivering simplicity and security benefits while providing the reliable connectivity that OT environments require.

Seamlessly Manage Security Operations for OT Assets, 5G Devices and Remote Operations with Strata Cloud Manager

IT-OT Convergence has accelerated the need to support more secure remote access and site-to-site connectivity for OT environments. As customers look at SASE-based approaches to secure remote operations, they want solutions that can achieve several key objectives. These include implementing Zero Trust security consistently across wired and wireless OT site-level networks. Additionally, customers want solutions that offer consolidated insights and can be managed in a unified, operationally efficient manner.
