GeoTrust vs lego

GeoTrust Horizon is a security platform for SSL certificates, certificate automation and monitoring, and vulnerability management. GeoTrust says it is intended for small and medium businesses and fast-moving builders. It offers DV, OV, and EV certificates issued from DigiCert trusted roots. AutoInstall SSL automates certificate installation, re-issuance, and renewal, supporting Apache, NGINX, IIS, LiteSpeed, cPanel, Kubernetes, Docker, and more. With automatic renewal enabled, certificates renew 28 days before expiry. SSL Monitor checks domains and subdomains daily for certificate expiry, trust issues, HTTPS vulnerabilities, and more than 110 SSL issues. Vulnerability Manager scans servers daily for more than 375,000 vulnerabilities and provides remediation instructions; scans can be internal with an installed agent or external without one. GeoTrust says the tool uses Qualys vulnerability detection technology. SSL Monitor costs $2 a month per standard domain, and Vulnerability Manager costs $12 a month per server. Technical chat support is available 24/7; email support uses tickets and phone support is available five days a week.

lego is an independent, free, open-source ACME client and Go library for obtaining, renewing, and revoking certificates. It supports wildcard and SAN certificates and can work with multiple ACME servers, including Let’s Encrypt and ZeroSSL. Validation choices include DNS-01, HTTP-01, TLS-ALPN-01, and DNS-PERSIST-01. The project lists more than 200 DNS providers, including Cloudflare, Amazon Route 53, Google Cloud DNS, and Azure DNS, with CNAME support enabled by default. Users can run lego from the command line or call it as a Go library. DNS credentials and settings are supplied through environment variables, with file references and dotenv files supported. Installation options include prebuilt binaries, Docker, package managers, and source. The maintainers look after the AUR and Snap packages; other listed packages are community maintained. The project lists support for ACME RFC 8555 and certificate validation and renewal extensions. It is licensed under MIT, and installing from source requires Go 1.25 or later. The project points to GitHub issues and discussions for help.
