Yes, this is exactly what our Flagging feature was designed for. If Flagging is turned on, you can flag the phone number, email address, IP address, and 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). You can even add a comment when flagging a value. Other users will then see if the value appears in a transaction and can create their own rules based on this shared knowledge.
