    In security implementation perspective we need to secure Sitefinity backend which requires following implementation.

    • Place a restrictions to block each IP which exceed the number of login from 3-5.
    • Need to check if the user is already logged in and from which IP they are accessing the logged in section. If  the same IP is accessing the Login form for 5 user then it should block any other user from the same IP to login to coordinator section.


    Seems some custom provider implementation is required. but not sure how.

    Now, be aware that filtering by IP address is not always a foolproof way to blacklist a potential attacker depending of your network topology. In particular, an attacker could use the same external IP address as other legitimate users (if accessing your website from the same external company, same public wifi, etc.)
