Daniel Horvath
Founder and Senior Penetration Tester
Dan became a penetration tester in 2017, after serving within a specialist cyber crime unit in his local police force.
During his career, Dan has worked for multiple security consultancies and helped defend organisations in both the public and private sector.
A specialist in both external perimeter and internal enterprise network penetration testing, Dan believes that a true security testing engagement must encompass the entire attack surface, else it's not providing full security assurance.
Dan is passionate about helping businesses become more secure and founded Adversify off the back of a desire to provide penetration testing services that move past theoretical risk and help businesses defend against current real-world adversaries.
Dan's vision was to create a business of like-minded offensive security professionals who want to go above and beyond for businesses and openly share knowledge with our clients and the community, to improve cyber security for all organisations.
