Publicizing mass infections

Sucuri became famous when they started to publicize the tools used on mass attacks against sites hosted at GoDaddy. GoDaddy criticized them for sharing too much information and possibly helping the attacks. In their defense, it was stated that everything they posted was already known by the black hat community, and it only helped the users to understand and better protect themselves.

Sucuri uses the principle of responsible disclosure to raise awareness about software vulnerabilities on their website security blog.
