About

Feisty Duck is a small publisher of good computer books run by Jelena and Ivan, a husband and wife team from London, UK.

Our focus is computer security, building on Ivan's many years of work in this field. We have developed a unique platform for continuous publishing, which ensures that our books remain fresh despite the fast pace of change in technology.

In 2016, we introduced high-quality computer security training. Courses include SSL/TLS, Internet PKI and Apache/ModSecurity and are available as on-site or public trainings.
