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 screening job applicants, 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 who they claim to be.
Two Ways to Use Polyguard¶
There are two ways to put Polyguard to work: use one of our products, or license and embed the technology in your own application.
Use Polyguard's products¶
Ready-made products that protect each stage of the employee lifecycle, with no new tools for your team to learn.
PreScreen¶
PreScreen verifies job applicants at the source. It adds a Trust Check to your application flow, so bot-submitted, synthetic, and fraudulent candidates are stopped before they reach your applicant tracking system. The verified identity is written onto the application record. PreScreen works with Greenhouse, Rippling, and Workday.

Remote Interviews¶
Polyguard integrates with Zoom and Microsoft Teams to add identity verification to remote interviews. Every participant's identity is verified before and during the call, so deepfake and proxy candidates cannot pass. You can schedule protected meetings from Outlook, Teams, or Zoom.

Help Desk Security¶
Password resets and MFA resets are a leading target for social engineering. Polyguard adds identity verification to the help desk workflow, so IT teams can confirm a caller's identity before making any account change. Employees verify through Polyguard Mobile on their own device in under a minute.

Build with Polyguard¶
Platform customers use the Polyguard SDK and REST API to embed trust checks directly into their own web or mobile applications. Any authentication or authorization step, including account creation, high-value transactions, age verification, and 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¶
Every Polyguard product and integration runs on the same engine: fused identity. Polyguard verifies independent factors on one device and fuses them into a single tamper-proof verification.
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 person is who they claim to be.
Document¶
Government-issued identity documents, including passports with NFC-enabled chips, driver's licenses, and national identity cards, are verified on-device. Cryptographic checks on NFC chip data confirm document authenticity, and verification can be completed offline.
Device¶
Hardware attestation, using 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, so 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 person actually is.
PG-Presence¶
PG-Presence is Polyguard's patented optical distance bounding technology. It flags the use of remote desktop connections, screen sharing, and network KVM devices, which traditional liveness checks cannot see. By confirming the verified person is physically present at the device, PG-Presence closes the gap between device location and person location that remote-access tools exploit. Together these factors produce a continuous presence check that holds up against the techniques attackers use today.
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 stay in control of their personal information at all times.
Litigation-Ready Records¶
Every trust check produces a non-repudiable, cryptographically signed record, the 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.
