Questions & Answers

SHIELD's answer

Most fraud solutions are web-first and rely heavily on personal data and static identifiers that are easily bypassed. They are also often focused on addressing fraud at specific checkpoints. SHIELD is device-first. Fraudsters can spoof data, accounts, and even identities, but they always need a device to act. This is why we stop fraud at the root.

Why should a person choose your product over its competitors?

SHIELD's answer
