SD-WAN solutions optimize application experience and provide secure, dynamic connectivity across distributed locations by leveraging real-time path metrics (latency, jitter, loss).

“By implementing SD-WAN, traffic is routed intelligently based on real-time network performance metrics. Zone protection profiles ensure security while maximizing application performance.”

Key advantage:

Secure connectivity and best user experience across campuses and branches.

Single floating IP address (also known as a floating IP or shared IP) is supported only in an active/passive HA pair. In active/active HA, both firewalls are forwarding traffic simultaneously and thus do not share a single floating IP.

“In active/passive HA, a single floating IP address is used for seamless failover. Active/active HA requires separate IP addresses and does not support a single floating IP.”

This simplifies failover in active/passive deployments by using a single shared IP that moves to the active peer upon failover.

Client-based VPN solutions like GlobalProtect provide full coverage for the mobile workforce by extending the enterprise security stack to remote endpoints. It establishes a secure tunnel, allowing consistent security policies across the enterprise perimeter and the mobile workforce.

“GlobalProtect is a client-based VPN that provides secure, consistent protection for mobile users by extending the security capabilities of Prisma Access to remote endpoints, covering all network protocols.”

Heartbeat polling is a core HA function to monitor connectivity between HA peers, leveraging ICMP pings to determine link health and availability.

“Heartbeat Polling uses ICMP pings to verify the connectivity and health of the HA peers. If heartbeat polling fails, the firewall considers the peer to be down and may initiate failover.”

If ICMP pings fail, checking heartbeat polling logs helps identify if link or path monitoring triggers the failover.
