Founder story

From the lab to Primitive Labs

I’m Zenith, a Threat Hunter, DevSecOps specialist and the creator of Primitive Labs. I work where offensive security, digital forensics and secure software development meet.

My path started by taking systems apart to understand how they were built. Web development gave me an engineer’s perspective; CTFs, controlled labs and vulnerability research taught me where assumptions fail.

I created Primitive Labs to bring those two perspectives together and help businesses reduce digital exposure before it becomes an incident. The goal is not a longer list of findings—it is clear risk, practical remediation and stronger systems.

My public work spans secure web tooling, a simulated forensic investigation and authorized security labs. Find me as ZenithHacking on GitHub and LinkedIn.

How it works

My Process Is Precision

Simple. Transparent. Focused on results and security.

How I work

Offense. Evidence. Engineering.

The same three disciplines shape my research, my development work and the way I am building Primitive Labs.

01

Think like an attacker

Challenge assumptions in authorized environments and look for the paths a conventional checklist can miss.

02

Prove it with evidence

Preserve context, reproduce findings and document impact clearly enough for technical teams to act.

03

Build the correction

Move beyond reporting: prioritize risk, help remediate, harden the system and retest when needed.
