Work With Me

Hi, I’m Ghislain — aka Guisch. I’m a security engineer: I break things, I fix things, and in between, I run this blog. I started GSociety to share raw, real-world security stories: bugs that shouldn’t exist, tools I built to prove a point, design flaws hiding in plain sight. No fluff, no buzzwords — just lessons that stick. If it matters, breaks things, or makes me laugh, it’s here.

I help companies build security that makes sense, scales well, and doesn’t get in the way. I work as an independent consultant, usually on long-term missions where I can really dig in, solve problems, and build things that last. Whether you need a security engineer or someone to lead your security efforts, I can help.

Over the past few years, I’ve helped startups and scaleups make sense of security — from getting the basics right to building scalable security programs. Sometimes that means diving into tech. Other times, it’s about helping a company think like an attacker before one shows up.

🚀 How I can help

I usually step in as one of two things:

1. Security Engineer

Need someone who actually enjoys fixing broken things, setting up sane defaults, or building tools that save you from yourself? I’ve been there. Whether it’s hardening infra, chasing down bugs, or getting alert fatigue under control — I can help.

2. Security Lead / (Fractional) CISO

No security team yet? Or you're not ready for a full-time CISO? I can jump in, assess where you are, where you want to go, and what’s worth fixing right now. I’ll bring clarity, structure, and a roadmap that won’t get laughed out of your next board meeting.

🧠 Who I work with

I work best with startups and scaleups who:

• Have no security team yet and want to build something smart (not just compliant)

• Have a tiny team and need someone to lead, mentor, or scale it
• Care about real-world risks more than checkbox audits

💬 A bit about me

For two years, I ran security at Heetch. I’ve done a lot with little, built programs from scratch, and solved problems most people didn’t know they had.
