About Jobyer Ahmed

I'm Jobyer Ahmed, an offensive security researcher and founder of Bytium LLC. For fifteen years I've worked the attacker side of the table: red-teaming enterprises, breaking software others assumed was solid, and helping leaders turn findings into decisions they can defend.

My week is genuinely mixed. I might reverse-engineer a CRM appliance to find a bug nobody else has spotted, run a full-scope engagement against a production network, then sit in a boardroom and explain why the issue should change next quarter's roadmap. The hands-on work and the advisory work feed each other.

I hold nine industry certifications, including OSCE³, CISSP, and OSCP. The full list is below. What they don't capture is the working philosophy behind them: rigorous about evidence, honest about uncertainty, aligned with what the business actually needs to protect.

I founded Bytium LLC in 2024 to do this work at scale with a small, senior team. Before that I ran Rednode Services Ltd, a research lab that published CVEs against widely-deployed software and trained offensive operators. Those disclosures, and the engagements behind them, are catalogued below.
