Remo is a graphical rule editor for ModSecurity, an Apache security module. ModSecurity is quite difficult to configure successfully. Modsecurity.org advertises a tested core ruleset granting you protection from most known attacks, but this is only blocks traffic known to be dangerous, when it is more effective to block everything not known to be safe. Remo is meant to assist in the difficult task of writing the rules that would correctly describe the requests that are valid for an application.
