What are Firewall Apps for iPhone?

Firewall software is a security tool that monitors and controls incoming and outgoing network traffic based on predetermined security rules. Acting as a barrier between a trusted internal network and untrusted external networks, firewalls help prevent unauthorized access and protect against cyber threats. They work by analyzing data packets and determining whether they should be allowed through based on set policies, blocking potentially harmful traffic. Modern firewalls often incorporate advanced features like intrusion prevention, application filtering, and deep packet inspection to strengthen security further. By providing this critical layer of protection, firewall software safeguards sensitive data and ensures the integrity of networked systems.
