Flexibility, Predictability, and Quality over quantity are the traits that define ModSecurity. They are passive application software pre-installed in your cPanel which gives lots of information and lets you make the decision.
It can monitor real-time application security and access control along with full logging of HTTP traffic for security purposes. Traditional tools only log some of the data. Hardening of the web application is another feature of it which helps in reduction of attack surface.
ModSecurity is enabled by default in all domains hosted with us. However, you are free to disable the service whenever you like to by going to cPanel > ModSecurity.
