## What it is
Certify The Web is an ACME v2 certificate management application with a Windows desktop UI and background renewal service, plus a cross-platform self-hosted Management Hub for centralized administration. It automates requesting, deploying, and renewing free SSL/TLS certificates from Let's Encrypt and other ACME CAs, with deep IIS integration and DNS validation support.

## Use cases
- automatically renew letsencrypt certificates on windows iis
- get free ssl certificate for my website
- manage wildcard certificates with dns validation
- centralized certificate management across multiple servers
- deploy certificates to exchange or nginx automatically
- automate https setup for windows server
- monitor certificate renewal status across an organization

## When to choose
- you run Windows Server/IIS and want automated Let's Encrypt certificates with a GUI
- you need centralized, multi-server certificate management via a self-hosted hub
- you want DNS challenge validation with many DNS provider integrations
- you need automated deployment tasks to Exchange, Apache, nginx, Azure Key Vault, etc.

## When to avoid
- you prefer a free open-source CLI like certbot or win-acme for simple scripted use
- you need a fully open-source solution with no licensing limits (free edition caps at 5 certificates)
- you only run Linux and want a lightweight command-line ACME client
- you need certificates from CAs without ACME v2 support
