PeerGuarding.. Where to start.... As a local business owner, it is important to keep my internet network safe. Without PeerGuardian, I never truly knew who was connecting to my internet connections as my shop. With PeerGuardian, I know exactly who is connecting and who I can accept and reject from connecting. Peerguardian is a must for all homes, businesses, and massive corporations alike!

PeerGuardian is a tool that I use in order to protect and increase my privacy. It's a firewall application that cuts off any connectivity to any set of IP addresses, no matter how massive that set might be. I've been able to block millions of addresses that I want to blacklist for good, which makes this my go-to privacy application.
