An enterprise browser with Google taken out and the defaults locked down.
Prismara Browser is a hardened, de-Googled build of Chromium for Windows, macOS and Linux. It keeps the web compatibility people expect from Edge and Chrome, ships with strict security defaults, signs in with your existing company account, and is managed centrally.

Taken from the working demo, using sample data.
What Prismara Browser does
Hardened defaults
JavaScript JIT off by default, strict site isolation and DNS over HTTPS.
Google removed
No Google sign-in, sync or background services, and no unexpected network connections.
Company sign-in
Single sign-on with Entra ID through the operating system on Windows and macOS.
Central policy
One policy file generates Windows registry, macOS profile and Linux settings. Customer overlays can only tighten it.
Security events
Signed, hash-chained security events for Prismara SOC or Microsoft Sentinel, written to the system log on each platform.
Open source where it counts
Full corresponding source for the LGPL parts is published with every release.
How it's secured
Prismara Browser follows the engineering rules shared across the suite, plus these product-specific measures.
Fast patching
Targets: 24 hours for exploited vulnerabilities, 48 hours for critical and high, 72 hours for routine fixes, 7 days for a new major version.
Zero unexpected egress
Every build is tested against a logging proxy to catch connections nobody asked for.
Signed releases
Update manifests are signed with Ed25519.
