You can use content editor webpart to run javascript. Java script will redirect users from accessing the site. You need t o specify the user Id; it wont work on DL
Blow is the java script:
==================Script Start ===============
ExecuteOrDelayUntilScriptLoaded(getWebUserData, "sp.js");
var context = null;
var web = null;
var currentUser = null;
    function getWebUserData() {
        context = new SP.ClientContext.get_current();
        web = context.get_web();
        currentUser = web.get_currentUser();
       currentUser.retrieve();
        context.load(web);
        context.executeQueryAsync(Function.createDelegate(this, this.onSuccessMethod), Function.createDelegate(this, this.onFailureMethod));
    function onSuccessMethod(sender, args) {
        var userObject = web.get_currentUser();
        if (userObject.get_loginName() == 'i:0#.w|domain\userid')
           window.location="/businesses/pulpandfibre";
    function onFailureMethod(sender, args) {
        alert('request failed ' + args.get_message() + '\n' + args.get_stackTrace());
=============Script End===============
