SiFA is Designed to Stop Email and Payments Fraud Before It Happens
Monroe, La. USA & Melbourne, Australia – Dec 10, 2025 – In a significant advancement for global cybersecurity and digital trust, identity-security provider Krown Technology and quantum-safe security company ExeQuantum today announced a jointly engineered patent for Signature Factor Authentication (SiFA), a new category of cryptographic, automated multifactor authentication designed to prevent fraud before it occurs.
SiFA solves one of the most persistent challenges in enterprise security: determining whether a high‑risk instruction truly originates from the correct person, on the correct device, with the correct intent. By binding identity, device metadata, and cryptographic assertion together, SiFA drastically reduces the success rate of account takeovers, malware injection, and AI‑driven impersonation attempts.
Already being piloted with one of Australia’s largest construction groups, SiFA delivers device-bound, identity-verified digital signatures that instantly validate who is truly behind a communication or approval — even in the presence of account takeover, malware, session hijacking, or AI-generated impersonation attempts.
At a time when AI-driven fraud, business email compromise (BEC), and payments redirection attacks are accelerating exponentially across Australia, APAC, and the US, SiFA introduces what experts are calling the first practical, cryptographic defense that enterprises can adopt without complex infrastructure changes.
A New Category: Automated MFA That Operates in Milliseconds, With Zero User Friction
Where traditional MFA relies on human action (codes, approvals, prompts), SiFA moves identity verification fully into the cryptographic layer.
It binds identity + device + intent and validates them programmatically in milliseconds. If the signature does not match the correct cryptographic context, the action simply does not proceed.
Delivered as a lightweight Outlook add-in, SiFA requires minimal user training, no new behavior beyond additional integration, and no tech no-how, making it immediately deployable across enterprise environments.
Stopping Fraud at the Source
Payments fraud, invoice redirection, procurement tampering, and supply-chain impersonation attacks all share one pattern: a trusted identity is hijacked at the moment of instruction. SiFA shifts trust away from human perception and into cryptographic certainty.
If the signature isn’t cryptographically valid, the instruction gets blocked or flagged.
This is a fundamental change in how organizations can defend themselves against AI-enabled malicious actors.
