Certbot vs Keyfactor Platform

Certbot is free, open-source software from the Electronic Frontier Foundation for enabling HTTPS on websites that administrators manage themselves. It obtains Let’s Encrypt certificates and can install them on a web server automatically in many cases. The command-line tool names Apache and Nginx integrations, along with webroot and standalone methods. DNS validation avoids requiring an inbound connection from Let’s Encrypt, so it does not depend on an existing HTTP site or an open port 80. Certbot renews certificates when less than one-third of their lifetime remains; for certificates lasting 10 days or less, renewal occurs when half their lifetime remains. It is generally run on a Unix-like server, often remotely over SSH, and is intended for administrators comfortable with command-line work on a dedicated server, VPS or cloud-hosted server. The project points users to its documentation and the Let’s Encrypt community forum for help.

Keyfactor Platform, through Keyfactor Command, gives PKI, security, infrastructure, and DevOps teams visibility into certificates and tools to govern their lifecycle. It can inventory certificates from certificate authorities, scan networks for unknown SSL/TLS certificates, and connect to key and certificate stores. Teams can automate enrollment, renewal, revocation, and provisioning, with self-service workflows available through a user interface or API. Listed enrollment protocols are SCEP, ACME, and EST. Administrators can set role-based permissions, protect private keys with retention and storage policies, and require enrollment or approval workflows. Integrations span CI/CD, cloud, HSM, IoT, ITSM, public and private certificate authorities, and web servers. Deployment options are on premises, as a hosted certificate lifecycle service, or as fully managed PKI in a single-tenant cloud platform. Keyfactor says Command has been tested for deployments with more than 500 million certificates. A 30-day trial is offered. Pricing is available on request, and there are no per-certificate fees listed.
