Bitgo Holdings Inc. has unveiled a five-layer security model aimed at enhancing the safety of institutional digital asset transactions. Announced on April 30, the model introduces checks across intent, device, identity, behavior, and policy to mitigate manipulation risks before transactions are finalized. This approach addresses sophisticated threats such as deepfakes, API spoofing, and address manipulation. The new security framework allows institutions to implement additional controls, including transaction approvals, address restrictions, and velocity limits. The policy layer, in particular, enables firms to enforce rules that operate independently of cryptographic authorization, ensuring that transactions can be blocked if they violate internal controls, even if they are valid at the signing level. Bitgo's initiative reflects a shift towards securing not just the cryptographic keys but also the transaction context and behavior, providing a comprehensive defense against emerging threats.
