Privacy settings for public networks in Brave.

Introduction

When you connect to a public network—coffee shops, airports, hotels, libraries—you expose your device to a range of privacy and security risks. Unsecured Wi-Fi hotspots can be breeding grounds for eavesdropping, man-in-the-middle attacks and tracker injection. Brave Browser, with its built-in privacy tools and configurable Shields, offers an effective first line of defense. This article explores how to tune Brave’s settings for maximum privacy on public networks.

Understanding the Risks of Public Networks

Common Threats

• Eavesdropping (sniffing unencrypted traffic to read sensitive data)
• Man-in-the-Middle Attacks (intercepting and altering communications)
• Tracker Injection (adding trackers into pages you visit)
• Malicious Hotspots (fake Wi-Fi points set up to harvest credentials)
• Session Hijacking (stealing active login tokens for websites)

Why Brave Matters on Public Wi-Fi

Brave combines ad- and tracker-blocking with HTTPS enforcement, fingerprint randomization and optional Tor routing. By configuring its Shields and privacy settings, you reduce the attack surface exposed on any untrusted network.

Configuring Brave for Maximum Privacy

1. Adjusting Brave Shields

Brave’s Shields panel (the lion icon next to the address bar) lets you control various protections on a per-site or global basis. For public Wi-Fi, tighten these defaults:

• Block Ads Trackers: Prevents third-party trackers and ads from loading.
• Block Cross-Site Trackers: Stops trackers that follow you across domains.
• Block Third-Party Cookies: Ensures cookies from external domains are blocked.
• Fingerprinting Protection: Reduces the uniqueness of your browser fingerprint.
• Block Scripts (Optional): Stops potentially malicious scripts—but may break site functionality.

To set these globally, open Settings gt Shields amp Privacy gt Default shield settings.

2. Enforcing Secure Connections

Always encrypt your web traffic by forcing HTTPS whenever possible:

• Enable “Always Use HTTPS” in Settings gt Security.
• Brave’s built-in HTTPS Upgrades will attempt an encrypted version of every site.

3. Secure DNS (DNS over HTTPS)

A public network’s DNS can be compromised to redirect you to malicious sites. Brave supports DNS over HTTPS (DoH):

• Go to Settings gt Privacy amp Security gt Use Secure DNS.
• Choose Automatic or configure a trusted provider (e.g., Cloudflare, Google, Quad9).

4. Clearing Browsing Data Automatically

When youdisconnect from a public hotspot, erase traces of your session:

• Enable “Clear Browsing Data on Exit” under Settings gt Privacy amp Security.
• Select data types: history, cookies, cached images, site settings, etc.

5. Managing Site Permissions

Public networks should not have access to your camera, microphone or location by default:

• Settings gt Privacy amp Security gt Site and Shields Settings.
• Review Permissions for location, camera, microphone, notifications.
• Set default to “Ask before accessing” or “Blocked”.

6. Using Private Windows with Tor (Mobile Only)

Brave on iOS and Android offers a “Private Window with Tor” feature that routes traffic through the Tor network, masking your IP address and preventing local network snooping:

• Open a new tab and choose “Private with Tor.”
• Note that performance is slower, but anonymity is significantly enhanced.

Advanced Tips for Public Network Privacy

• Use a System-Level VPN: Complement Brave’s shields with a trusted VPN service to encrypt all traffic.
• Avoid Captive Portals: Only authenticate on networks you trust captive portals can inject tracking scripts.
• Disable Auto-Connect: In your OS Wi-Fi settings, turn off automatic connections to open hotspots.
• Monitor Certificate Warnings: Never bypass SSL/TLS warnings—attackers often use invalid certificates on rogue hotspots.
• Keep Brave Updated: Regular updates ensure you have the latest security patches and fingerprinting protections.

Summary

By combining Brave’s Shields, HTTPS enforcement, secure DNS, data clearing and strict permissions, you can browse safely on any public network. For even stronger anonymity, use Brave’s Tor integration or a third-party VPN. With these settings in place, your personal data and browsing activity stay protected, even on the most insecure Wi-Fi hotspots.
