2. Set up customized rules to determine suspicious travel times: Establish rules that take your users' normal login patterns into account to accurately identify cases of impossible travel. For example, you can set a rule to flag sessions as suspicious when users log in from two locations more than 500 miles apart within just 3 hours.

   
   

3. Flag or block suspicious sessions for manual review: When the system identifies a suspicious session based on your established rules, it should either flag it for further investigation or block the session outright. This will depend on your platform's specific policies and the risk associated with the potential multi-accounting fraud attempt.

   
   

4. Train your staff on how to analyze suspicious sessions: Once the system flags a suspicious session, your IT staff or fraud prevention team should know how to review it accurately and efficiently. They should be able to analyze login data, identify the root cause of the alert, and determine whether the session is due to multi-accounting fraud or a false positive.

   
   

5. Continuously update your geolocation database and refine your rules: As cybercriminals evolve their techniques and new IP addresses become available, ensure that your database is frequently updated with the latest information. Additionally, monitor the effectiveness of your existing rules and modify them when necessary to keep up with changing patterns and trends in multi-accounting fraud.
