What does “Audited by Netcraft” actually mean?
“Audited by Netcraft” does not mean that the site or network is impregnable, but shows that the site is actively maintaining its security against remote compromise from the Internet. Each site or network displaying the “Audited by Netcraft” seal is keeping the audited site or network address space free from well known remote attacks, and has an Internet’s eye view with which to manage its external security. The “Audited by Netcraft” seal is served dynamically and shows the date of the last clean test, when no serious well-known vulnerabilities that could permit remote compromise were detected.
