Overview:
The Palo Alto PA-5450 ML-Powered NextGeneration Firewall (NGFW) platform is designed for hyperscale data center, internet edge, and campus segmentation deployments. Delivering incredible performance—120 Gbps with security services enabled— it is based on a scalable, modular design that enables you to increase performance as your needs increase. The PA-5450 offers simplicity defined by a single-system approach to management and licensing
The world’s first ML-Powered NGFW enables you to prevent unknown threats, see and secure everything—including the Internet of Things (IoT)—and reduce errors with automatic policy recommendations. The controlling element of the PA-5450 is PAN-OS, the same software that runs all Palo Alto 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 time.
PA-5450 Architecture
The PA-5450 is powered by a scalable architecture for the purposes of applying the appropriate type and volume of processing power to the key functional tasks of networking, security, and management. The device is managed as a single unified system, enabling you to easily direct all available resources to protect your data. The PA-5450 intelligently distributes processing demands across three subsystems, each with massive amounts of computing power and dedicated memory: the Networking Cards (NC), the Data Processing Cards (DPC), and the Management Processing Card (MPC).
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)
- 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 pro- prietary 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 files and thwart exfil- tration 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.
Enables SD-WAN functionality
- Allows you to easily adopt SD-WAN by simply enabling it on your existing firewalls.
- Enables you to safely implement SD-WAN, which is natively integrated with our industry-leading security.
- Delivers an exceptional end user experience by minimizing latency, jitter, and packet loss.
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).
Delivers a unique approach to packet processing with Single-Pass Architecture
- Performs networking, policy lookup, application and de- coding, and signature matching—for all threats and con- tent—in a single pass. This significantly reduces the amount of processing overhead required to perform multi- ple functions in one security device.
- Avoids introducing latency by scanning traffic for all signa- tures in a single pass, using stream-based, uniform signa- ture matching.
- Enables consistent and predictable performance when security subscriptions are enabled. (In Table 1, “Threat Prevention throughput” is measured with multiple sub- scriptions enabled.)
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 lever- age 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 wait- ing 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, lap- tops; 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.
We can ship to virtually any address in the world. Note that there are restrictions on some products, and some products cannot be ship to international destinations.
Please also note that the shipping rates for many items we sell are weight-based. The weight of any such item can be found on its detail page. To reflect the policies of the shipping companies we use, all weights will be rounded up to the next full pound.
