Digital Trust Infrastructure

Every signature,
verified before it's questioned.

PKI Pro builds the infrastructure enterprises trust to sign, seal and audit their documents. Our flagship product, SecureSign Pro, turns HSM and USB-token signing into a batch job — not a bottleneck.

SecureSign Pro

An enterprise signing engine for teams who process documents by the hundred, not the handful — connected straight to your HSM or USB token, no manual clicking through Adobe.

01

Bulk signing engine

Point it at a folder, walk away. Every PDF inside is signed against your certificate in one pass, with a per-file result you can audit.

02

HSM & token support

Works with PKCS#11 devices out of the box — Thales ProtectServer, SafeNet, and standard USB DSC tokens — without vendor lock-in.

03

Adobe-trusted appearance

Signatures render with a verified green check the moment Acrobat opens the file, backed by the Adobe AATL chain of trust.

04

Scheduled automation

Real-time, interval, or a fixed daily schedule — set a watcher on your input folder and let SecureSign Pro sign as files land.

05

Enterprise dashboard

Signed-today counters, device health, DSC expiry countdown, and a live execution log — the whole signing operation, at a glance.

06

REST API engine

Wire signing directly into your ERP, DMS, or invoicing pipeline with a straightforward API — no UI required in production.

How it works

From token to trusted PDF, in three steps

SecureSign Pro is built to disappear into your existing workflow, not add a new one.

Connect your device

Plug in a USB token or point SecureSign Pro at your HSM's PKCS#11 library. It reads live slot and certificate status immediately.

Configure the signature

Set the stamp position, header text, and reason once — every document afterwards inherits the same trusted appearance.

Automate and monitor

Run it on demand, on a schedule, or as a folder watcher, and keep an eye on signed/failed counts from the dashboard.

Next from PKI Pro

SecureCLM Pro Early access

The same trust infrastructure, pointed at your certificate estate. SecureCLM Pro is a multi-CA certificate lifecycle platform that discovers, issues, renews, and deploys certificates across your servers automatically — HSM-backed, audit-ready, and built to stop the 2am expiry outage before it happens.

01

Multi-CA orchestration

DigiCert, Sectigo, GlobalSign, Microsoft ADCS, and your own internal CA — issue and manage from one console instead of five vendor portals.

02

HSM-backed keys

Thales Luna, Thales ProtectServer, Entrust nShield, and Utimaco — keys are generated and held on the HSM, never exposed in transit.

03

Zero-touch deployment

Auto-deploy renewed certificates straight to IIS, Linux (nginx/Apache), F5, and FortiGate — agentless over WinRM/SSH, or via a lightweight mTLS agent.

04

Network discovery

Point it at a subnet and it finds every live certificate on your estate — no more spreadsheet of "which server has which cert."

05

Expiry alerts & auto-renewal

See what's expiring before it becomes an outage, and let SecureCLM Pro renew and redeploy it automatically — no calendar reminders required.

06

Full audit trail

Every issuance, renewal, and deployment is logged — the same audit-ready standard SecureSign Pro already holds for signatures.

Why PKI Pro

Built for teams who can't afford a broken signature

Every product we ship is held to the same standard: keys stay on hardware, deployment stays on your infrastructure, and every action leaves an audit trail.

01

HSM-backed security

Private keys are generated and used inside PKCS#11 hardware — Thales, Entrust, Utimaco, or a USB DSC token — and never touch disk in the clear.

02

Certificate automation

Discovery, issuance, renewal, and deployment run on a schedule instead of a spreadsheet reminder, so nothing expires unnoticed.

03

Multi-CA support

DigiCert, Sectigo, GlobalSign, Microsoft ADCS, or your own internal CA — manage them all from a single console.

04

Enterprise integrations

Ships with connectors for the HSMs, CAs, servers, and clouds enterprise teams already run — no custom glue code required.

05

On-premise deployment

Runs on your own Windows or Linux infrastructure, next to your HSM or token. Keys and documents never leave your network.

06

API-first architecture

Every product exposes a REST API first, so signing and certificate operations can be wired directly into your own systems.

Enterprise integrations

Fits into the stack you already run

No rip-and-replace — PKI Pro connects to the HSMs, CAs, servers, and clouds already sitting in your infrastructure.

Hardware Security Modules

Thales Luna, Thales ProtectServer, Entrust nShield, Utimaco — PKCS#11 out of the box.

Public & internal CAs

DigiCert, GlobalSign, Sectigo, and Microsoft ADCS for on-premise issuance.

Cloud platforms

AWS and Azure key stores and certificate services, alongside your on-premise HSM.

Web & app servers

Automated deployment to IIS, Apache, NGINX, and F5 — agentless, over WinRM or SSH.

Security architecture

Keys never leave the hardware

Every product in the PKI Pro line is designed around the same principle: the private key stays on the HSM or token, and only the operation result crosses the wire.

01

Zero key exposure

Signing happens inside the PKCS#11 session on the device itself — only the document hash goes in, only the signature comes out.

02

On-premise by default

Software runs on your own Windows or Linux infrastructure. Documents, keys, and certificate data never go to an external cloud.

03

Full audit trail

Every signature, issuance, renewal, and deployment is logged — a running record of what happened, when, and against which certificate.

04

Standards-based trust

Built on PKCS#11, PAdES long-term validation, and the Adobe AATL chain of trust — nothing proprietary for recipients to install.

05

Role-based access

Control who can trigger a signing run, issue a certificate, or view the audit log — not every user needs every permission.

06

Encrypted in transit

Every hop between the application, the HSM, and your servers is encrypted — nothing crosses your network in the clear.

Where it fits

Built for teams who sign at scale

Any workflow that ends in "print, sign, scan, email" is a candidate.

Contracts & agreements

Vendor, employment, and NDA paperwork signed the moment it's generated, not days later.

Invoices & purchase orders

Finance teams batch-sign hundreds of invoices at month-end without touching Acrobat once.

Compliance & filings

Board resolutions, statutory letters, and regulator filings signed with a full audit trail.

Vendor & dealer onboarding

Manufacturing and dealer networks push signed agreements out at the volume onboarding actually needs.

Questions

Common questions about PKI Pro

Product-specific questions? See the SecureSign Pro FAQ or SecureCLM Pro FAQ.

Is PKI Pro cloud-hosted, or does it run on our own infrastructure?

Every PKI Pro product runs on your own Windows or Linux infrastructure, next to your HSM or token. Documents, keys, and certificate data never go to an external cloud service.

Do our private keys ever leave the hardware?

No. Whether it's SecureSign Pro signing a document or SecureCLM Pro issuing a certificate, the private key stays on the HSM or token — only the operation result crosses the wire.

Which HSMs and CAs does PKI Pro support?

Thales Luna, Thales ProtectServer, Entrust nShield, and Utimaco HSMs; DigiCert, Sectigo, GlobalSign, and Microsoft ADCS for certificate authorities — see the full integrations list.

Do SecureSign Pro and SecureCLM Pro work together?

Yes — both are built on the same trust infrastructure. SecureCLM Pro can manage the very certificates SecureSign Pro signs with, so renewals never interrupt a signing pipeline.
