This a "soft-firewall" package. Its purpose is to help people prevent unauthorized access to routes by IP address. It is able to keep track of IPs, countries and hosts (dynamic ip), and redirect non-authorized users to, for instance, a "Coming Soon" page, while letting whitelisted IPs to have access to the entire site. It is now also able to detect and block attacks (too many requests) from single IPs or whole countries. This package can prevent some headaches and help you block some access to your apps, but cannot replace firewalls and appliances, for attacks at the network level, you'll still need a real firewall.
