What is PhishFlagger™?
PhishFlagger™ provides protection by adding to Communications a unique sequential number, the PhishFlagger™, visible to the user.


How Does PhishFlagger™ Work?
PhishFlagger™ inserts an upcounted sequential number in the subject line, called the PhishCounter™, from the sender. The recipient will see this number and be able to verify if it matches the last email sent (Human Compatible) or it will be automatically flagged as out of sequence by an application or domain (Auto-Flagging). In both cases, the recipient is protected from fraudulent senders.

Any Email Domain can join the PhishFlagger Protocol. We also enable Marketers, Portals and Security Providers.

Caller ID
Sequence Number known only by valid carrier and callee prevents impersonation.
As the existing Caller ID rail is fully interoperable globally, a 'sequence number'
could be implemented by telecoms worldwide to help authenticate calls.
Numbering has been revolutionary in creating identifiable order to records and documents, thereby reducing fraud.
