What is Polyguard?¶
Polyguard is a real-time identity verification platform that stops deepfakes, impersonation, and social engineering before they cause harm. Whether you are securing a video interview, verifying a caller on the help desk, or embedding trust checks into your own product, Polyguard confirms that the person on the other end is exactly who they claim to be.
Three Ways to Use Polyguard¶
Secure Meetings¶
Polyguard integrates with Zoom and Microsoft Teams to add real-time identity verification to any video meeting. Scheduling workflows in Outlook and leading ATS systems let organizers protect meetings with a single click.
Primary use case today: Securing job interviews against deepfake candidates and impersonation. Every participant's identity is verified continuously throughout the call — not just at the start.

Help Desk and Password Reset¶
MFA and password resets are among the most common targets for social engineering attacks. Polyguard adds identity verification to the help desk workflow so IT teams can confirm a caller's identity before making any account changes.
Employees verify through Polyguard Mobile on their own device. The process takes under a minute and creates a tamper-proof record of the verification for audit and compliance.

Embed in Your Product¶
Platform customers use the Polyguard SDK to embed trust checks directly into their own web or mobile applications. Any authentication or authorization challenge — account creation, high-value transactions, age verification, or access control — can be backed by Polyguard's identity infrastructure.
The SDK handles the full verification lifecycle: creating trust check links, launching the mobile verification flow, and returning cryptographically signed results to your backend.

The Technology Behind It¶
Polyguard's core technology verifies four independent factors and combines them into a single trust decision: the person, the document, the device, and the location.
Person¶
Real-time facial recognition uses 3D depth analysis to confirm a live human is present in front of the camera, blocking deepfakes, face swaps, and replayed video. The face is matched against a verified identity document to confirm the participant is who they claim to be.
Document¶
Government-issued identity documents — passports (including NFC-enabled ePassports), driver's licenses, and national identity cards — are verified on-device. Cryptographic checks on NFC chip data confirm document authenticity. Document verification can be completed even when offline.
Device¶
Hardware attestation (Apple AppAttest and Google Play Integrity) confirms the verification is running on a genuine, unmodified mobile device. Cryptographic keys are stored in the device's secure enclave, ensuring that verification results cannot be forged or replayed from another device.
Location¶
Polyguard combines GPS and GNSS location data from the mobile device with PG-Presence to confirm not just where the device is, but where the meeting participant actually is.
PG-Presence¶
PG-Presence is Polyguard's patented optical distance bounding technology. It detects the attempted use of remote desktop connections, screen sharing, or network KVM devices by meeting participants — attacks that traditional liveness checks cannot see. By confirming that the verified person is physically present at the device, PG-Presence closes the gap between device location and participant location that remote-access tools exploit.
Together, these four factors produce a continuous presence check that is resistant to the techniques attackers use today — and the ones they will develop tomorrow.
Privacy First¶
Polyguard is built on a privacy-first architecture:
- Biometric data and identity credentials stay on the user's device. They are never uploaded to the cloud.
- Cryptographic keys are stored in the device's secure enclave (Apple Secure Enclave or Android hardware-backed keystore).
- Verification results are signed locally and transmitted as tamper-proof tokens — not raw biometric data.
Users remain in full control of their personal information at all times.
Litigation-Ready Records¶
Every trust check produces a non-repudiable, cryptographically signed record — a Transaction Affidavit — that documents what was verified, when, and on what device. These records are designed to withstand legal scrutiny and satisfy audit and compliance requirements.
