Palo Alto Networks secures AI use through its firewalls, SASE service and enterprise browser. AILeakShield delivers AI discovery, control and prompt protection in the browsers staff already use, and can also feed a restricted-AI blocklist to an existing Palo Alto firewall.
What Palo Alto Networks is: AI Access Security with Enterprise DLP, enforced through Palo Alto NGFW, Prisma Access or Prisma Browser, plus Prisma AIRS for securing AI that companies build.
Yes means documented. Partial means limited, an add-on, a separate product or preview. Not documented means we could not find it in the vendor's public documentation; it does not mean the vendor has tested and failed it.

Palo Alto Networks: AI Access Security needs a Strata Logging Service license plus AI Access Security, a CASB license or Prisma Browser, and enforcement through an NGFW, Prisma Access or Prisma Browser. End-user coaching needs Prisma Access and the Enterprise DLP license. Prices are not published.
AILeakShield: A browser extension for Chrome, Edge and Firefox, installed silently through Google Admin, Microsoft Intune, Group Policy or Jamf, plus firewall and DNS log import and an optional read-only Microsoft 365 connection. No proxy, no TLS inspection and no new browser. Everything is in one subscription, sold through IT providers and distribution including TD SYNNEX, with no seat minimum. Most organizations start in monitor mode.
AILeakShield is designed to work with a Palo Alto firewall: its restricted-AI domain feed can drive an External Dynamic List, while AILeakShield handles prompt protection and governance in the browser.

For employee AI use, yes. AILeakShield discovers AI tools, blocks unapproved ones and protects prompts without Palo Alto network infrastructure. Palo Alto is broader for network security and for securing AI applications you build.
Yes. AILeakShield publishes a per-tenant list of restricted AI domains that a Palo Alto External Dynamic List can consume, so a decision made in AILeakShield is enforced at the firewall too.
No. AILeakShield runs as an extension in Chrome, Edge and Firefox.

AILeakShield discovers all the AI in your environment, blocks the AI tools you have not approved, and keeps sensitive data out of the prompts sent to the ones you have.
