Comodo Firewall Pro brings a revolutionary change to internet security with Default Deny Protection (DDP?) technology. The security tool provides the very best protection against online threats like malware, spyware, trojans and hackers.

What is DDP?

Conventional security programs which determine if a file should be allowed access to the computer based on offline malware definitions. If the definition misses some entries or doesn't have updated malware list, virus and malicious codes will easily gain access to your PC.

DDP works in the cloud to get up-to-date definitions plus a list of files from trusted vendors. The firewall refers to a list of over 2 million PC-friendly applications before authorizing access to a request. Programs that cannot be verified as safe are run in a secure isolated area called the sandbox, providing perfect protection because you are even protected from threats that have not yet been identified
