Prisma Access Browser alternative
The Prisma Access Browser alternative without the cloud tether.
Palo Alto's Prisma Access Browser is a forked browser managed from the Strata cloud, with detection anchored in Palo Alto's global services. Surface keeps detection on-device and telemetry inside your perimeter — as a managed extension on the browser your users already run, with no SASE subscription required.

Why security teams choose Surface over Prisma Access Browser
Prisma Access Browser solves real problems. But when the requirement is detection that learns your environment, data that never leaves your perimeter, and a rollout that does not touch the browser your users already trust, Surface is the stronger fit.
Detection that learns your environment
Prisma Access Browser leans on Advanced URL Filtering and WildFire — cloud services built on global intelligence. Surface Vision baselines your own traffic on-device, so a phishing kit cloned from your login pages is caught first, not last, with no sample ever leaving for a vendor cloud.
No cloud tether, no SASE lock-in
Prisma Access Browser has no self-hosted option: policy, posture, and session forensics land in the Strata Logging Service. Surface runs entirely on your infrastructure — air-gapped if needed — and works without a Prisma Access subscription or platform ecosystem.
No fork tax on patching
A forked browser is patched on Palo Alto's rebuild timeline, and its EOL policy only covers the latest version. Surface adds no fork: the extension rides on the Chrome, Edge, or Firefox your users already run, patched on the upstream vendor's native cadence.
Switching is a push, not a project
The reason most teams go looking for an alternative in the first place is the migration: replacing everyone's browser is a rollout with retraining, helpdesk load, and compatibility workarounds. Surface skips that entirely.
Keep your browser
Surface installs as a managed extension in the Chrome, Edge, or Firefox your users already open every morning. No second browser, no retraining.
Keep your perimeter
The control plane runs on your infrastructure — Docker, Kubernetes, VMs, bare metal, or fully air-gapped. Telemetry lands in your SIEM, not a vendor cloud.
Keep your patch cadence
No fork sits between Chromium and your fleet. Browser security fixes arrive on the upstream vendor's native timeline, not a rebuild pipeline.
Surface vs. Prisma Access Browser, capability by capability
The same data from our full head-to-head, scored on architecture, not marketing. Surface leads on sovereignty, adaptive detection, and deployment; we mark honestly where Prisma Access Browser still wins.

Prisma Access Browser has real strengths — last-mile DLP depth, BYOD containment, and iOS and Android browser coverage Surface does not match today. If you are all-in on Prisma SASE, that integration is genuine, and we say so on the record.
