Secure Internet Browsers

A secure internet browser blocks trackers, stops malware, and keeps your data private. The best ones also help you work safely. Tabbit is built on Chromium's hardened security core and adds AI-powered protection that reads pages before you click.

The Basics

What makes a browser secure?

Most people think 'secure browser' means one thing, but it's actually five layers working together.

01

Tracker & ad blocking

Stops advertisers and data brokers from following you across the web.

02

Anti-phishing & malware

Blocks fake login pages and malicious downloads before they reach you.

03

Anti-fingerprinting

Makes your device harder to identify even when cookies are cleared.

04

Automatic HTTPS & sandboxing

Encrypts connections and isolates tabs so one bad site can't take over.

05

Privacy by default

Collects the minimum data needed and makes privacy settings easy to find.

The Blind Spot

Why blocking lists can't protect you alone

Every mainstream secure browser relies on blocklists — known trackers, known malware domains, known phishing pages. That works for yesterday's threats, but not today's.

1

AI-generated phishing pages

Attackers now use AI to create realistic fake login pages that aren't on any blocklist yet.

2

Zero-day threats

A brand-new malicious site can slip through until a list is updated and pushed to your browser.

3

You are the target

Customized spear-phishing messages target your exact context — blocklists can't know that context.

4

Safety of AI tasks

As AI agents start acting for you, you need a browser that keeps those tasks isolated and auditable.

Tabbit's Security Model

AI-native security that goes beyond blocking

Tabbit keeps Chromium's hardened security core, then adds four AI-powered layers that make the browser safer for real work.

01

AI reads pages before you click

Tabbit's AI parses page content in your context. It can summarize a page, extract key facts, and flag suspicious patterns so you can decide before you commit — no blind clicking into phishing traps.

02

Agent tasks run isolated and visible

When you ask the AI agent to do work, it runs in its own tab group. Every step is visible and reversible, and your personal tabs stay untouched — a safety model traditional browsers simply don't have.

Auditable AI research

Deep Research shows its sources and reasoning, so AI-generated answers can be traced back to real pages. No black-box decisions when the stakes are your data.

You control which AI sees your data

Tabbit lets you pick from multiple top models. You decide which provider processes your context, and @-mention references show exactly what the AI is looking at — nothing hidden.

By Scenario

Which secure browser should you pick?

Your best choice depends on what you're protecting. Here's a quick guide.

Online banking & payments

Tabbit

Workspace isolation keeps banking separate from work and personal tabs, and the AI phishing guard reads payment pages before you enter credentials.

Public Wi-Fi (coffee shop, airport)

Tor or Tabbit

Tor adds network-layer anonymity; Tabbit adds AI threat reading plus HTTPS upgrades while staying fast enough for real work.

Deep research with AI

Tabbit

Deep Research returns traceable sources, so AI findings can be verified — something no blocklist-based browser offers.

Maximum anonymity

Tor Browser

If your priority is hiding your identity at all costs, Tor's relay network is the gold standard.

Family shared computer

Tabbit

Separate workspaces and visible AI tasks keep each family member's browsing isolated and auditable.

FAQ
