SafePhrase Enterprise
Verify the human,
not just the login.
MFA proves a device. It cannot prove the person on the phone. SafePhrase adds a live, rotating phrase that confirms a real, enrolled human, stopping voice-cloning and help-desk social engineering before it costs you.
Human-to-human caller authentication for the deepfake era.
The new attack surface
MFA was never built to verify a voice.
Deepfake-voice CEO fraud, business email compromise and help-desk social engineering are now board-level risks. Traditional MFA confirms a login or a device. It says nothing about whether the human on the phone is really who they claim to be. That is the gap attackers walk straight through.
Where it fits
Six high-value places to verify a caller
IT help desk verification
When an employee calls for a password or MFA reset, they read back the live phrase. A voice-cloning attacker can fake the voice but cannot produce the phrase without the enrolled device. Closes the exact gap behind recent help-desk breaches.
Payment & wire authorisation
Require the live phrase before any wire transfer or change to vendor bank details. Stops deepfake-CEO and business email compromise fraud that slips past email and MFA.
Vendor & supplier changes
Confirm it is really your supplier before updating payment or mandate details. Kills invoice-redirection fraud with a five-second check on the call.
Privileged & third-party access
Verify the engineer from your vendor, or an MSP, before granting privileged or remote access. The caller proves they are an enrolled, trusted human.
Client and institution trust
Private banks, law firms and wealth managers verify high-value clients on the phone, and let clients verify the institution back. Two-way trust, white-labelled to your brand.
Customer support protection
Give your customers a way to confirm an inbound call is genuinely from you, not an impersonator, cutting support-line fraud and protecting your brand.
How it works
Enrol once, verify on every call
SafePhrase verifies people you already have a relationship with, your staff, clients and known vendors. It is enrol-then-verify, not first-contact, so it is built for the calls that actually matter.
Enrol your people
Add staff, clients or known vendors. Each enrolled person installs the app once and joins your organisation.
A live phrase on every device
Everyone enrolled sees the same rotating phrase, generated on-device and refreshed every minute.
Confirm before you act
On any call, ask for the phrase before resetting access, moving money or sharing sensitive data.
Built for security teams
Designed to resist the attack, not just log it.
The same zero-knowledge engine that protects families is what makes SafePhrase hard to phish at work. There is no shared secret on a server to steal, and a rotating phrase is useless the moment it is overheard.
Admin console, SSO and SCIM directory sync, audit logging and SOC 2 are on the enterprise roadmap. Tell us your requirements and we will share where we are.
- check_circlePhish-proof and clone-proof: the phrase lives only on enrolled devices and rotates every minute.
- check_circleZero-knowledge by design: phrases are generated on-device and are never sent to or stored on our servers.
- check_circleWorks on any channel: phone, video call or in person, with no special hardware.
- check_circleFast to roll out and priced per seat, with low friction for the people using it.
