Backend php website for our audit tool

We need a website with the following features built. I would also like to have a chat.

The website itself:-

Session Management:-

Once a user logs a unique session is started the sourceIP and the browser type is stored, this is used to check against session stealing.

We regenerate the session token if we see the same token from multiple sources

SQL injection:-

We use parameterized sql queries to avoid this issue.

Cross side scripting:-

WE use a token to is part of a hidden form and send to the client whenever a post is done the tokens are compared to see if they are valid.

Traffic between the components:-

Traffic between the client - webserver - database are all encrypted (SSL).

Survey API:-

traffic from the survey API to the databases are also encrypted using SSL, however no encryption happens between then factory worker and the api(SMS and IVR).

Instance Access:-

Access to the server instance(CentOS) is only done by means of SSH.
