What You'll Learn
Palo Alto Firewalls can act as core routers
Palo Alto Networks, Inc. is an American multinational cybersecurity company that provides a platform that includes advanced firewalls and cloud-based offerings that extend those firewalls to cover other aspects of security. Palo Alto's next-generation firewalls detect known and unknown threats, including in encrypted traffic, using intelligence generated across thousands of customer deployments.
Using Palo Alto Firewalls as core routers provides several benefits. One user mentions that the app visibility and granular control make lateral movement of a malicious actor difficult. Palo Alto Firewalls can also be used for segmentation and lateral threat protection.
When considering using Palo Alto Firewalls as core routers, it is important to check the current throughput/backplane on the core network devices before choosing which Palo Alto device to purchase. The design is also an important factor to consider. It is also worth noting that Palo Alto Firewalls may not be suitable for large networks. One user mentions that their baby 220 is limited to 15 security zones, making it suitable for small 10 to 15 people sites.

Palo Alto Firewalls can be used in small-medium businesses
Palo Alto Networks' next-generation firewalls are purpose-built with end users in mind. Their ML-Powered NGFWs offer the same world-class security provided to Fortune 500 companies, tailored to small and medium-sized businesses. Palo Alto's firewalls are designed with flexible and scalable designs to meet specific deployment needs, providing complete and consistent protection across your business.
Small and medium-sized businesses often have sensitive information that cybercriminals want but may lack the security infrastructure to protect themselves. Palo Alto's firewalls detect known and unknown threats, including in encrypted traffic, using intelligence generated across thousands of customer deployments. They enable users to access data and applications based on business requirements and prevent credential theft.
Palo Alto's single-pass architecture employs a unique single-pass approach to packet processing, delivering better performance and security. Their firewalls classify network traffic by the application's identity, granting user access and providing visibility and control of all types of applications to administrators.
Palo Alto's firewalls can also act as core routers, with an increasing trend of replacing all routers in small and medium-sized businesses with Palo Alto's products. This is especially beneficial for segmentation and lateral threat protection. Palo Alto's Panorama provides centralized management capabilities, offering easy-to-implement, consolidated monitoring of managed firewalls, Log Collectors, and WildFire appliances.
Overall, Palo Alto's firewalls are a comprehensive and effective solution for small and medium-sized businesses, providing robust security, performance, and flexibility to meet specific needs.

Palo Alto's PA-850 cannot act as an NTP server
Palo Alto Networks' next-generation firewalls can detect known and unknown threats, including in encrypted traffic, using intelligence generated across thousands of customer deployments. However, the PA-850 cannot act as an NTP server for other network devices. While there is no documentation demonstrating support for using a PA-850 as an NTP server, it is possible to NAT the IP address on the interface to a real NTP server. This allows the firewall to translate the address to another address, ideally, the real IP address of the device being Natted for, in a different subnet.
For example, if the NTP server IP address is 10.1.1.1, the Palo Alto firewall can translate this to 10.2.2.250, which then becomes the NTP server. This scenario is applicable if there is a small number of hosts on the subnet. In cases where there are many hosts on the subnet, a local solution may be more suitable.
Additionally, it is worth noting that Palo Alto firewalls can act as core routers. This is a common practice, especially in small to medium-sized businesses, where the PAN firewall serves as the router/gateway in their network.

Palo Alto's PA-500 is a good firewall
Palo Alto Networks' PA-500 is a next-generation firewall that provides high-performance processing and dedicated memory for networking, security, threat prevention, URL filtering, and management. It is ideal for medium to large branch offices and medium-sized enterprises, delivering robust firewall security to Internet gateway deployments. The PA-500 is designed to ensure network security and threat prevention, utilizing dedicated computing resources to manage network traffic flows effectively.
One of the key advantages of the PA-500 is its ability to provide a smooth pathway between processors. The high-speed backplane separates data and control planes, ensuring that management access remains available regardless of traffic load. This feature enhances the user experience by minimizing latency, jitter, and packet loss.
The PA-500 is controlled by PAN-OS™, a security-specific operating system. PAN-OS™ enables organizations to safely enable applications using App-ID, User-ID, Content-ID, GlobalProtect, and WildFire. This operating system provides comprehensive visibility and control over applications used across all users and devices, ensuring that allowed traffic is free of known and unknown threats.
In addition to its robust security features, the PA-500 also offers centralized management capabilities through Panorama™. This feature simplifies monitoring and management of firewalls, Log Collectors, and WildFire appliances, providing easy-to-implement solutions for network administrators.
The PA-500 is a reliable choice for organizations seeking to secure their networks. With its advanced processing capabilities, dedicated resources, and robust security features, it effectively safeguards medium-sized enterprises and branch offices from a broad range of cyber threats.
