Andy is a hacker(ハッカー) at heart, an adversarial architect, an offensive security leader, an engineer and a consultant who has 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).
In his day job, Andy Gill is a security consultant focusing on offensive security through and through; as of 2023, he has been in the security industry for over 14 years! He is passionate about offensive security and specialises in red teaming and simulated attacks. He strives to further defensive technologies to assist clients with technological and strategic issues.
In recent years he has focused more on contextualising risk and findings from pentests and similar engagements to help clients prioritise remediations, with more of a focus on cloud technologies such as Microsoft Azure.
With a hunger for knowledge and paying it forward, Andy actively helps grow the community by mentoring and educating the masses on security awareness, paired with his excellent consultancy skills.
Andy has previously held CREST’s CCT Infrastructure certification, which is highly sought-after; he has also previously held CHECK Team Leader status. He is also a Certified Red Team Operator. He is working towards attaining several Microsoft Azure cloud certifications to bolster his achievements and accolades.
To back up his years in the industry, he holds several other certifications and accolades, including OSCP and 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 the US Dept. of Defense, MindGeek, Facebook and Oracle.
He has also published two books aimed at those looking to get into security, and both follow along different areas showing paths and areas to look at. They can be purchased on both Amazon and Leanpub:
- Breaking Into Information Security: Learning The Ropes 101 - Amazon |Leanpub
- Expanding Your Security Horizons: Learning The Ropes 102 - Amazon | Leanpub
Passing on Knowledge
For those that don't know Andy, he is a firm believer in passing knowledge on and supporting the infosec community. He does this by providing tutorials on his blog (/), and running his local DEF CON Chapter. He also helps out at DEF CON as a SOC Goon (Red Shirt) each year (since DC25), assisting the SOC with operations and people flow.
Both his book and blog have won awards:
- UnsungSecHeroes 2021 - Best Cyber Writer
- EU Cyber Security Bloggers Award 2020 - Best Personal Security Blog
He can be found on most mediums on the internet as @ZephrFish, and is always happy to help folks if they have questions. DMs are open on Twitter.
Aside from the blog and book, Andy has started a podcast with one of his good friends, who is learning the ropes.

However, aside from all the technical goodness, his life isn't wholly spent behind a terminal as he also enjoys training martial arts; holding a 1st Dan black belt in Karate with over nineteen years of 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 essential with the work of pentesting or any home-based security role that people have an escape away from the keyboard!
Andy is also a keen photographer who loves getting out and about and taking pics of all sorts.
