Introduction to the basics of Let's Encrypt for securing professional websites, installation of the test environment with Certbot on Linux, exploration of the ACME protocol for fee-free domain validation, initial practical exercises to obtain test certificates, manual HTTPS configuration on a local server, analysis of logs to understand secure flows, and creation of an initial diagnostic report for your domain.
In-depth hands-on with Certbot to generate Let's Encrypt certificates in production, step-by-step installation on Ubuntu and CentOS with dependency management, practical exercises on virtual servers to obtain and install wildcard certificates, integration with Docker for secure containers, DNS and HTTP-01 validation tests, resolution of common real-world errors, and production of a functional certificate ready for deployment.
Configuration of automatic Let's Encrypt renewals to prevent service interruptions, setup of cron tasks with Certbot and dry-run testers, development of custom hooks to restart services after renewal, exercises on monitoring with tools like Certbot-timer, simulation of enterprise expiration scenarios, integration with email/Slack notification systems, and drafting of a certificate maintenance plan for your infrastructure.
Practical application of Let's Encrypt on Apache and Nginx to enable full HTTPS, generation of secure configurations with HTTP to HTTPS redirection, activation of HSTS and OCSP stapling for optimal performance, hands-on workshops on real or virtual servers, tests with SSL Labs to achieve A+ scores, resolution of multi-domain certificate conflicts, and optimization of certificate chains for mobile browsers, delivering a production-ready professional web stack.
Anticipation of Let's Encrypt 2026 changes such as ACME v3 and shorter certificate durations, full audit of current deployments with analytical tools, advanced troubleshooting exercises on rate-limit errors and revocations, setup of certified backups and multi-ACME migrations, case studies of businesses impacted by updates, development of an incident response playbook, and completion of the red thread project with an operational production certificate and strategic report.
