On 2/20, my site was experience a large amount of SQL Injection and DirTraversal attacks. Thanks to Protector module, it catched all the attacks, and my site survived. Thank you GIJOE for developing such a grate module. Thank you very much.
It's my pleasure.
Have you enabled "DB-Layer Anti-SQL-Injection"? I believe It's really useful for securing from malicious attacks.
Don't forget checking databasefactory.php is replaced.
