What it does
TinyWall is a free Windows firewall with temporary rules, blocklists, UWP support and a workflow intended to avoid frequent connection popups.
TinyWall is aimed at someone who wants application-network controls without approving a stream of popup prompts. Its current homepage lists temporary rules, blocklists and UWP support. Review the applications that need network access before applying the policy, then use temporary rules for a short-lived exception rather than leaving a permanent opening. The useful distinction is the deliberately quieter administration workflow.
Strengths
- Temporary rules and blocklist controls
- Workflow designed around fewer connection popups
Best for
