Palo Alto buys Portkey to secure AI agent traffic

Palo Alto is adding Portkey’s AI gateway into Prisma AI Runtime Security, giving the platform a more direct role in controlling and securing AI agent traffic. For teams building or operating AI applications, the acquisition points to runtime security moving closer to the gateway layer rather than sitting only around the application. In the broader stack, it reinforces that AI agent security is becoming a distinct product category inside enterprise security platforms. The next concrete signal to watch is how Palo Alto describes Portkey’s integration inside Prisma AI Runtime Security after the deal closes.
