1. What is TinyWall?

TinyWall is a minimalist, no-frills firewall designed for Windows systems. Unlike traditional firewalls that rely on constant pop-ups and rule-based configurations, TinyWall operates silently, blocking unauthorized connections by default.

How TinyWall Works

• Default-Deny Approach: Blocks all inbound and outbound connections unless explicitly allowed.
• Process-Based Filtering: Controls network access based on applications rather than ports.
• Automatic Whitelisting: Safely permits essential Windows services to prevent system issues.
