DescriptionBy analyzing error codes and messages returned from some web queries, Nessus is able to determine that the remote web server is protected by a web application firewall.
Such protection may disrupt scan results. Countermeasures have been taken to make the scan as reliable as possible.
SolutionTo get a more comprehensive set of scan results, either whitelist the Nessus server's IP address or scan from an unprotected location.
