Dr.-Ing. Mario Heiderich
Founder of Cure53
Dr.-Ing. Mario Heiderich is from Berlin, likes everything between lesser- and greater-than and leads a small yet exquisite pen-test company called Cure53. He also maintains the DOMPurify project, helps with the HTML Sanitizer API specification and knows a bit about HTML and browser security.
He believes that the best chocolate comes from Belgium and the best cheese from France – and will probably need a bodyguard in Bern.
