“Sigma Synthetic is Socure's synthetic identity fraud detection product, designed to identify and combat synthetic identity fraud at the point of onboarding and throughout the account lifecycle.”
Sigma Synthetic appears to be a fraud detection product or capability — specifically focused on synthetic identity fraud — rather than a standalone operating company with a publicly documented history. The primary evidence is a Socure press release announcing 'Sigma Synthetic Fraud,' which positions it as a Socure product launch targeting synthetic identity fraud detection.
