You can manage all blacklisted, whitelisted and flagged values in your account from the Lists page. In order to add new values to the blacklist or whitelist, you can either enter the fields and values manually or upload a CSV file for faster action. 

In both cases, when you click Load, you'll see a list of the items that are to be added to the respective lists. You can then review the values and click Add to list to finalize the black/whitelisting; comments and expiration dates can be added too. 



Blacklisting a value will set the score to 100 for every transaction in the future containing the given data point. Only blacklist anything if you are certain that all related transactions are suspicious

We recommend blacklisting browser hashes, IPs for a limited time (90 days maximum recommended) as well as user IDs, emails, phone numbers and cookie hashes.



Whitelisting a value will set the score to 0 for every transaction in the future containing the same data field.

As with the blacklist, we suggest only whitelisting values that are more specific, such as user IDs, email addresses, card hashes, etc., as some more general data points can cause false negatives (such as an ISP or card’s bank name).


Custom Lists

With Custom Lists, you can watchlist certain transactions and interactions without creating new rules with layers of parameters. Use this tab to monitor accounts, transactions, or users and test assumptions before making any changes.

Monitor suspicious activity: When you notice a sudden spike in suspicious behavior from a certain location, you can create a watchlist that monitors IPs from that specific area.

Test assumptions: No need to comb through the logs manually when you need to check something. Filter customers and transactions using the available data fields and save your search as a Custom List.

Update rules: Once you validate your watchlist, you can easily add a new rule to SEON and assign a risk score to these transactions automatically.

How to use it

1. Open SEON and head to Lists.

2. Click the Custom List tab.

3. Click + Add new Custom List.

4. Name your list.

5. Click Add.

6. Click the + Plus sign right of the data fields.

7. Now, you’ll be redirected to the Add New tab, where you can import a list from a CSV file or enter the data points manually.

8. Once you’re done, click Add to list on the right.

You’re all done! Now you can reference this list when you set up Custom Rules.


Flagging as Suspicious

If flagging is turned on, you can flag the phone number, email address, IP address and the browser hash from the Transaction Details page by clicking the “Flag as suspicious” label under the value. 

Flagged values are shared across SEON clients (like a shared pool of suspicious data-points) and can be seen when the value appears in a transaction. Rules can be set up based on these values.
