Latest Post Surviving in the Ring: Expanding Your Horizons by Andy Gill


Andy is a hacker at heart, who's always been interested in taking things apart and sometimes even putting them together again(in-fact he spent a good few years in computer repair and data recovery).

As his day job, Andy works as a senior penetration tester who is capable of delivering a wide spectrum of assessment types. These include; web applications, external & internal infrastructure, open source intelligence gathering, configuration reviews and many more.


Andy has been in the IT security industry for just over five years, currently holding CREST’s CCT Infrastructure certification which is highly sought-after, in addition he holds CHECK Team Leader status. He is also working towards CREST's Certified Simulated Attack Specialist certification too.

To back up his years in industry he also holds several other certifications and accolades including OSCP, OSWP.

Coupled with his day job, Andy also participates in bug bounty programs, having reported bugs to over a hundred vendors including high profile targets such as US Dept. of Defense, MindGeek, Facebook and Oracle.

Passing on Knowledge

For those that don't know Andy, he is a strong believer in passing knowledge on and supporting the infosec community he does this by providing tutorials on his blog (https://blog.zsec.uk), running his local DEF CON Chapter & has also published a book Breaking into Information Security: Learning the Ropes 101.

He has also recently started a YouTube channel, discussing and teaching an overview of different security topics.

Non-Technical Things

However aside from all the technical goodness his life isn't completely spent behind a terminal as he also enjoys training martial arts; holding a 1st Dan black belt in Karate with over sixteen years experience, during which he has fought and competed at full contact level with an amateur record of 1 win, 1 loss and 2 draws.


It is important with the work of pentesting or any home based security role that people have an escape away from the keyboard!
