NMAP and Nessus require no introduction to the security community. Many security auditors have been using this combination for years. NMAP stands out from the other available port scanners for its efficiency and tweaking features.
Nessus takes over where NMAP leave off. NESSUS checks all open ports for various known protocols. Once the service running on the known port is determined, NESSUS then sends data to that service to exploit known security vulnerabilties.
