Works with your existing workflow
How it works
5 steps. Zero PIN exposure.
Watch the actual flow — the signing PC never touches your private key or PIN. Even with full admin access, there is nothing on it to steal.
- 1
Connect Your DSC
Plug your USB token into your Android or iOS device.
- 2
Initiate Signing
A user starts a signing process from any supported portal or application.
- 3
Receive Approval Request
The DSC holder receives a notification showing exactly what needs to be signed.
- 4
Approve Securely
Tap Approve on the mobile app. The signature is generated using the USB token.
- 5
Complete Instantly
The signed response is securely returned, and the workflow continues automatically.
One flow, two users
Two Users. One Secure Signature.
The host desktop sends signing requests; the mobile app holds the token and approves each request locally. This is exactly how both sides look.

Built for trust
Everything you need to sign remotely — safely.
eGuard replaces vendor-locked token SDKs with a secure-by-design relay that keeps the secret material where it belongs: in your hand.
PIN-proof by design
Your PIN is entered only on your phone and never travels over the network. There is no PIN to phish, log, or steal on the host.
Supported tokens
PROXKey, HyperPKI, Precision and MToken — detected automatically, powered by eGuard's own engine.
Zero-trust host
The signing PC holds no private key and no PIN. Full admin compromise still can't sign for you.
Full audit trail
Every signature is logged with device, timestamp and location, giving you a verifiable record for compliance and disputes.
Security model
Architecturally impossible to steal your PIN.
eGuard isn't “PIN protection” bolted on after the fact — the PIN and USB token simply never exist on the signing PC. There is nothing there to compromise, by design.
Your PIN stays on your phone
You enter your PIN only on your own phone — it never travels anywhere. There is simply nothing on the signing PC for anyone to steal.
Nothing signs without your tap
Every request needs your approval on your phone, and you see exactly what is being signed before you allow it.
3-factor authentication
Physical token (have), PIN (know), and bound mobile device (possess) — all three required to produce a signature.
Keys inside the chip
Private keys never leave the hardware token. Signing happens on-chip; the host only ever receives a finished signature.
Sign from any PC.
Keep your token in your hand.
Sign from any computer in the world — whether you are sitting in front of it or not. Install the eGuard host app on the PC, pair your phone, and start signing in Adobe, GST portals and Java apps — without ever exposing your PIN.
