Paulino Calderon (@calderpwn) is the co-founder of Websec, a company offering information security consulting services based in Mexico and Canada. When he is not traveling to a security conference or conducting on-site consulting for Fortune 500 companies, he spends peaceful days in Cozumel, a beautiful small island in the Caribbean, learning new technologies, conducting big data experiments, developing new tools, and finding bugs in software and devices.
Paulino is active in the open source community, and his contributions are used by millions of people in the information security industry. In 2011, Paulino joined the Nmap team during the Google Summer of Code to work on the project as an NSE developer. He focused on improving the web scanning capabilities of Nmap, and he has kept contributing to the project since then. In addition, he has been a mentor for students who focused on vulnerability detection during the Google Summer of Code 2015 and 2017. He is also a project leader of OWASP IoTGoat, a project about a deliberately insecure firmware to teach users about the most common vulnerabilities typically found in IoT devices.
He has published Nmap: Network Exploration and Security Auditing Cookbook (Now on its 2nd edition) and Mastering the Nmap Scripting Engine, covering practical tasks with Nmap and NSE development in depth. He loves attending information security conferences, and he has given talks and participated in workshops in dozens of events all around the world including China, Germany, Canada, United States, Mexico, Colombia, Peru, Bolivia, Chile, El Salvador, Honduras, and Curacao.
