Why us
Why Cyphlon?
We build what we deploy
The platforms in your engagement are products we build and run ourselves, so the engineers on your project know them from the inside.
Research, published and reproducible
We publish what we learn. Our study of LLM agents on web pentesting CTFs covers 2,700+ runs, and the paper and code are open.
People approve, AI assists
Senior engineers lead every engagement, and AI tools assist them. In DSO a person approves every AI verdict and fix. In OpsMaxx, AI agents never receive credentials, and every tool is allow, ask or deny with an audit log.
Senior, certified, regulated-industry advice
Our team holds CISSP, CISM, OSCP and CCSP certifications, and our advisory board brings practitioners from banking, healthcare and govtech.

An introductory call with our engineers about any engagement: a pentest, continuous testing, managed AppSec, security engineering, agentic AI security or a fractional CISO. We'll ask about your stack, your deadlines and what your customers or auditors expect, and tell you plainly if we're not the right fit.
