Pre-MVP · ACME connector for ADCS

Automate your internal certificates using your existing ADCS PKI.

Certeasy exposes your ADCS as a standard ACME server inside your own network. You install Certeasy on an internal server in front of ADCS, then point your ACME clients (like certbot) to https://acme.your-domain.local/directory or any internal URL you choose.

Simple flow
HTTP-01 On-Prem ADCS
Internal Clients certbot, acme.sh and any ACME client on Linux / Windows / appliances.

Certeasy does not add a new PKI: it automates the one you already have.

The problem today

In most organizations, ADCS issues certificates for Windows machines… but almost never for Linux servers, proxies, or internal appliances.

Teams want a Let’s Encrypt–style workflow for internal certificates: ACME requests, automated renewals, centralized visibility.

Fragmented PKI Manual certificates, custom scripts, different methods for each platform. Errors and expirations are inevitable.
Complex & costly tools Existing products are often oversized, expensive, or poorly integrated with ADCS.
No unified standard Very few tools provide a clean ACME-based workflow for internal PKI.

Certeasy: ACME on top of ADCS

Certeasy is a full ACME server that communicates directly with your ADCS. You continue using your internal PKI, templates, and policies — but through standard ACME clients.

V1 ACME HTTP-01
MVP: simple & deployable ACME server with HTTP-01 challenge, ideal for most internal environments, exposed behind a single endpoint.
V2 Distributed validators
For complex networks Deploy internal validation agents for segmented networks, without exposing ADCS.
V3 Dashboard & discovery
Global certificate visibility Inventory, expiration alerts, network scanning, and full insight into internal certificates.

Sovereignty & full control of your certificates

Certeasy is designed for organizations that want to automate their internal certificates without relying on any external cloud service. Everything runs inside your infrastructure, under your policies and your PKI.

100% on-premise Certeasy runs entirely on your own servers, inside your infrastructure. No external cloud service is required for issuance or validation.
No data ever leaves your network ACME requests, challenges, private keys and certificates remain strictly internal. Certeasy does not contact certeasy.tech and does not send telemetry.
Respects your existing PKI Certeasy does not add a new PKI. It relies on your existing Microsoft ADCS, your certificate templates and your security policies already validated internally.
Full legal & regulatory control Certificates are issued by your own Certification Authority, under your jurisdiction and your internal compliance rules — not a third-party SaaS provider.
No accounts, no multi-tenant cloud Certeasy has no cloud dashboard, no shared hosting and no tenant isolation. It is a self-hosted component fully controlled by your teams.
Offline by design Certeasy works in air-gapped or fully isolated networks. Updates can be applied manually, following your own internal processes.
