About
Built for engineers.
CyrusX is a platform built for engineers, security professionals, and network operators. The goal is simple — fast, practical intelligence tools that go beyond raw data and actually tell you what something means.
From subnet calculations to threat intelligence, CVE lookups, subdomain enumeration, BGP analysis, RF link budgets, and full-stack domain intelligence — every tool is designed to remove friction and surface insights, not just numbers. No ads, no bloat.
Why I built this
My name is Cyrus — an Electrical Engineer with a background in aviation, defense, RF, and communications, with hands-on experience across hardware, software, networking, and programming.
After years working in the field, I kept running into the same problem: the tools I needed were scattered across dozens of sites, calculators, and docs — none of them built for how engineers actually work. CyrusX is the toolkit I wished I had from day one.
Whether you're planning a network, doing security research, auditing a domain, enumerating attack surface, or working on a professional engineering project — these tools are built to be fast, accurate, and actually useful.
