Palo Alto Networks PA-450 Next Generation Firewalls

The Palo Alto Networks PA-400 Series, comprising the PA-460,  PA-450, PA-440, and PA-410, brings ML-Powered NGFW capabilities to  distributed enterprise branch  offices, retail locations, and midsize businesses. The world’s first ML-Powered Next-Generation Firewall (NGFW) enables you to prevent unknown threats, see and secure everything— including the Internet of Things (IoT)—and reduce errors with automatic policy recommendations.

Highlights 

• World’s first ML-Powered NGFW 
• Ten-time Leader in the Gartner® Magic Quadrant™ for Network Firewalls 
• Leader in the Forrester Wave™: Enterprise Firewalls, Q3 2020 
• Highest Security Effectiveness score in the 2019 NSS Labs NGFW Test Report, with 100% of evasions blocked 
• Spans a range of performance needs for the distributed enterprise with a broad lineup 
• Offers security in a desktop form factor 
• Extends visibility and security to all devices, including unmanaged IoT devices, without the need to deploy additional sensors 
• Supports high availability with active/active and active/passive modes 
• Delivers predictable performance with security services

The controlling element of the PA-400 Series is PAN-OS, the same software that runs all Palo Alto Networks NGFWs. PAN-OS® natively classifies all traffic, inclusive of applications, threats, and content, and then ties that traffic to the user regardless of location or device type. The application, content, and user—in other words, the elements that run your business—then serve as the basis of your security policies, resulting in improved security posture and reduced  incident response times. 

Key Security and Connectivity Features 

ML-Powered Next-Generation Firewall 

• Embeds machine learning (ML) in the core of the firewall to provide inline signatureless attack prevention for file-based attacks while identifying and immediately stopping never-before-seen phishing attempts. 
• Leverages cloud-based ML processes to push zero-delay signatures and instructions back to the NGFW. 
• Uses behavioral analysis to detect IoT devices and make policy recommendations as part of a cloud-delivered and natively integrated service on the NGFW. 
• Automates policy recommendations that save time and  reduce the chance of human error. 

Identifies and Categorizes All Applications, on All Ports, All the Time, with Full Layer 7 Inspection 

• Identifies the applications traversing your network  irrespective of port, protocol, evasive techniques, or  encryption (TLS/SSL); in addition, automatically discovers and controls new applications to keep pace with the SaaS explosion with a SaaS Security subscription. 
• Uses the application, not the port, as the basis for all your safe enablement policy decisions: allow, deny, schedule, inspect, and apply traffic-shaping. 
• Offers the ability to create custom App-ID™ tags for proprietary applications or request App-ID development for new applications from Palo Alto Networks. 
• Identifies all payload data within an application (e.g., files and data patterns) to block malicious f iles and thwart exfiltration attempts. 
• Creates standard and customized application usage  reports, including software-as-a-service (SaaS) reports that  provide insight into all sanctioned and unsanctioned SaaS traffic on your network. 
• Enables safe migration of legacy Layer 4 rule sets to  App-ID-based rules with built-in Policy Optimizer, giving you a rule set that is more secure and easier to manage. 
• Check out the App-ID Tech Brief for more information. 

Enforces Security for Users at Any Location, on Any Device, While Adapting Policy Based on User Activity 

• Enables visibility, security policies, reporting, and forensics based on users and groups—not just IP addresses. 
• Easily integrates with a wide range of repositories to leverage user information: wireless LAN controllers, VPNs,  directory servers, SIEMs, proxies, and more. 
• Allows you to define Dynamic User Groups (DUGs) on the firewall to take time-bound security actions without waiting for changes to be applied to user directories. 
• Applies consistent policies irrespective of users’ locations (office, home, travel, etc.) and devices (iOS and Android® mobile devices, macOS®, Windows®, Linux desktops, laptops; Citrix and Microsoft VDI and Terminal Servers). 
• Prevents corporate credentials from leaking to third-party websites and prevents reuse of stolen credentials by  enabling multi-factor authentication (MFA) at the network layer for any application without any application changes. 
• Provides dynamic security actions based on user behavior to restrict suspicious or malicious users. 
• Consistently authenticates and authorizes your users, regardless of their location and where user identity stores live, to quickly move toward a Zero Trust security posture with Cloud Identity Engine—an entirely new cloud-based architecture for identity-based security. Check out the Cloud Identity Engine Solution Brief for more information. 

Prevents Malicious Activity Concealed in  Encrypted Traffic 

• Inspects and applies policy to TLS/SSL-encrypted traffic, both inbound and outbound, including for traffic that uses TLS 1.3 and HTTP/2. 
• Offers rich visibility into TLS traffic, such as amount of encrypted traffic, TLS/SSL versions, cipher suites, and more, without decrypting. 
• Enables control over use of legacy TLS protocols, insecure ciphers, and misconfigured certificates to mitigate risks. 
• Facilitates easy deployment of decryption and lets you use built-in logs to troubleshoot issues, such as applications with pinned certificates. 
• Lets you enable or disable decryption flexibly based on URL category, source and destination zone, address, user, user group, device, and port, for privacy and compliance purposes. 
• Allows you to create a copy of decrypted traffic from the firewall (i.e., decryption mirroring) and send it to traffic collection tools for forensics, historical purposes, or data loss prevention (DLP). 
• Allows you to intelligently forward all traffic (decrypted TLS, non-decrypted TLS, and non-TLS) to third-party security tools with Network Packet Broker, optimize your network performance, and reduce operating expenses. 
• Refer to this decryption white paper to learn where, when, and how to decrypt to prevent threats and secure your business. 

Offers Centralized Management and Visibility 

• Benefits from centralized management, configuration, and visibility for multiple distributed Palo Alto Networks NGFWs (irrespective of location or scale) through Panorama network security management, in one unified user interface. 
• Streamlines configuration sharing through Panorama with templates and device groups and scales log collection as logging needs increase. PA-410, PA-440, PA-450, PA-460 allow export session logs to Panorama and Cortex® Data Lake. PA-440, PA-450, and PA-460 also support on box session logging. 
• Enables users, through the Application Command Center (ACC), to obtain deep visibility and comprehensive insights into network traffic and threats. 

Maximize Your Security Investment and Prevent Business Disruption with AIOps 

• AIOps for NGFW delivers continuous best practice recommendations customized to your unique deployment to strengthen your security posture and get the most out of your security investment. 
• Intelligently predicts firewall health, performance, and capacity problems based on ML powered by advanced telemetry data. It also provides actionable insights to resolve the predicted disruptions.
