Event description


The Best TLS Training in the World

Designed by the author of the much acclaimed Bulletproof SSL and TLS, this practical SSL training course will teach you how to deploy secure servers and encrypted web applications during a day packed with theory and practical work. We’ll focus on what you need in your daily work to deliver best security, availability and performance. And you will learn how to get an A+ on SSL Labs!

The course is taught in small classes.

Why This Course is for You

  • Understand threats and attacks against encryption
  • Identify real risks that apply to your systems
  • Deploy servers with strong private keys and valid certificates
  • Deploy TLS configurations with strong encryption and forward secrecy
  • Understand higher-level attacks against web applications
  • Use the latest defence technologies, such as HSTS, CSP, and HPKP

Target Audience

This course is for system administrators, developers, and IT security professionals, who want to learn how to protect their systems from eavesdropping and impersonation attacks.

Level: Intermediate
Duration: 1 day
Extras: Lunch and refreshments included

About a month prior to the course we'll send you a digital copy of Bulletproof SSL and TLS, our comprehensive guide to SSL/TLS and Internet PKI. You'll get the paper copy on the day. We'll also give you a bunch of exercises and a hardcopy of the slides.


  • Basic Linux command line skills: moving about, invoking commands, editing configuration files.
  • A laptop with a modern browser (Chrome or Firefox) and a SSH client, which you will only need to connect to your assigned virtual server. To connect to the server, you will need:
  • HTTP/HTTPS on ports 80 and 443
  • SSH on port 22
  • You should be comfortable using a command-line editor.

We'll provide you with your own virtual server and a sample web application to work on throughout the course.

We will also provide you with many additional exercises that you can work on in your own time. You'll be able to ask us for help via email. And if you're already familiar with the basics, we'll challenge you with some of the advanced exercises on the day.

Meet the Trainer

Scott Helme is a security researcher, consultant and international speaker. He can often be found talking about web security and performance online and helping organisations better deploy both.

Founder of, a free CSP report collection service, and, a free security analyser, Scott has a tendency to always be involved in building something new and exciting.

Meet the Author

Ivan Ristić is a security researcher, engineer, and author, known especially for his contributions to the web application firewall field and development of ModSecurity, an open source web application firewall, and for his SSL/TLS and PKI research, tools and guides published on the SSL Labs web site.

He is the author of three books, Apache Security, ModSecurity Handbook, and Bulletproof SSL and TLS, which he publishes via Feisty Duck, his own platform for continuous writing and publishing. Ivan is an active participant in the security community and you'll often find him speaking at security conferences such as Black Hat, RSA, OWASP AppSec, and others. He is currently working on his next exciting project called Hardenize.
