Six Pillars

Everything a browser should have been

EXCLUSIVE

War Room — Built In

Every URL scanned before the page loads. Live global threat intelligence sidebar. Red banner if you're about to visit a known malicious domain. No other browser has this.

UNIQUE

Bunker Mode

One toggle. Maximum hardening. All trackers blocked, WebRTC disabled, HTTPS forced, JavaScript fingerprinting killed, tracking parameters stripped. Incognito × 10.

BUILT IN

Encrypted Vault

Built-in password manager and secure file storage. End-to-end encrypted, local-first. Replaces LastPass and 1Password — no extension, no subscription, built right in.

OPEN

Multi-VPN Integration

WireGuard protocol built directly into the browser. Connect NordVPN, ProtonVPN, Mullvad, Surfshark, ExpressVPN — any provider, per-tab routing. You pay your provider. We handle the rest.

INTEGRATED

Productivity Sidebar

Pin Notion, Zoho, Slack, Gmail, Linear, Figma, and 50+ apps. Authenticate once via OAuth. They live in your sidebar permanently — no tab switching, no re-logging in.

REAL-TIME

SafeSearchScan Score — Live

Your digital health score updates in real time as you browse. Every site you visit, every file you touch — your score reflects your current exposure level.

VPN Hub

Your VPN. Your choice. Built in.

S3 Sentinel has WireGuard protocol built directly into the browser. Connect whichever VPN you already pay for — or sign up for one through our affiliate links at no extra cost to you.

Open Source

Built in the open. Trusted by design.

S3 Sentinel is built on Chromium and published open source on GitHub. Every line of code that handles your security, your vault, and your data is publicly auditable.

No telemetry. No ad engine. No data sold. The business model is subscriptions and VPN affiliate commissions — not your attention.

Core browser — Apache 2.0, free forever
War Room basic feed — open source
Bunker Mode — open source
Vault cloud sync — paid subscription
War Room Pro intel — paid subscription
