Setup guides & documentation

Find the guide you need to monitor your first site, set up automatic renewals or connect your team's tools.

Getting started

Add your first public website, connect an agent or bring in reports from your existing tools. The getting started guide walks you through each step.

Getting started guide

Automatic certificate renewals

Set up the agent to request certificates from Let's Encrypt or another compatible public ACME CA, then install and renew them locally. Configure domains, installation steps and optional weekly renewal windows.

Certificate workflows guide

CertIntel Agent

Install on Windows or Linux for automatic renewals and monitoring inside your network. Use the Windows desktop app or Linux CLI to choose which services and certificate files to monitor.

Agent setup guides

DNS verification

A one-time CNAME record lets CertIntel host the domain verification needed for issuance and renewal. Your agent or ACME client only needs access to its verification record.

DNS delegation guide

Your existing ACME clients

Keep Certbot, simple-acme/win-acme or Posh-ACME and connect their reporting integrations to see renewal activity in CertIntel.

Renewal reporting guide

Team access & sign-in

Invite your team and choose who can view or manage each organization. Use a local account or connect your OpenID Connect sign-in provider on plans with SSO.

SSO / OIDC setup

API, export & alert webhooks

Connect your own tools with API keys and JSON exports. On plans with alerts, send notifications to email, Slack, Teams, Discord, webhooks, Pushover or ntfy.

API keys & authentication

Security & privacy

Certificate private keys stay on the agent's machine and are never uploaded to CertIntel. Monitoring uses certificate details, and you can configure trusted authorities for internal certificates.

Privacy & cookies

The agent keeps certificate private keys locally. CertIntel receives certificate details, monitoring results and renewal reports. For privacy or data-processing questions, contact us.
