Palo Alto Prisma Access

Prisma Access delivers cloud access security broker capability as one component of a SASE platform, protecting users, applications, devices and data regardless of where they sit.

The CASB component provides deep visibility and control of all applications through SaaS Security Posture Management, combining inline and API based controls with contextual policies to protect sensitive data. Around it sit zero trust network access for least privileged application access without traditional VPN complexity, a secure web gateway using Precision AI for real time protection, remote browser isolation creating an isolation channel between users and remote browsers, and firewall as a service applying cloud native network security.

Buying these as one platform rather than five products is the actual proposition. Each function needs the same identity, device posture and traffic path, and assembling them separately means reconciling five policy models that disagree at the edges.

Palo Alto publishes unusually specific service commitments: 99.999 percent uptime SLAs, a 10 millisecond security processing SLA and a 35 millisecond SaaS performance SLA. Latency guarantees matter here because a security layer sits directly in the path of every request, so slow security gets bypassed by users. The company also claims five times faster application performance than direct to web through native application acceleration, a 50 percent reduced risk of breach, and 8.95 million new zero day threats prevented daily.
