Nullvector is a research-driven security company. We audit source code, break applications and run penetration tests the way real adversaries operate — and hand your engineers fixes they can actually ship.
Scanners find what's obvious. We find what's dangerous — logic flaws, chained bugs and the subtle mistakes that only show up when a human reads the code and thinks like an attacker.
Line-by-line review of your codebase by researchers who read code for a living. We trace untrusted input from source to sink and surface vulnerabilities static analysis can't reason about.
Deep assessments of web apps, APIs, mobile and desktop clients. We combine code access with live testing to prove impact — not just list theoretical issues.
Goal-oriented attacks against your external perimeter, internal network and cloud. We chain small weaknesses into real compromise paths and show you exactly how we got in.
Every engagement follows a rigorous, transparent process. You always know what we're testing, what we've found and what to do next.
We map your architecture, trust boundaries and crown jewels, then agree on a focused scope and clear rules of engagement.
Automated tooling sweeps for the low-hanging fruit so our experts can spend their time where it matters most.
Researchers dig into code and running systems, hunting for logic bugs, chained exploits and novel vulnerability classes.
Every finding is reproduced with a working PoC and rated by real-world impact, not theoretical CVSS inflation.
Critical issues are escalated the moment we confirm them. No waiting weeks for a PDF while you're exposed.
Developer-ready fix guidance, a walkthrough with your team and a free retest to confirm every issue is closed.
We're a new breed of security company: small, senior and obsessed with the craft. You work directly with the people who find the bugs.
Our team comes from vulnerability research, bug bounty and competitive CTF — not from reselling scanner output.
Automation assists, humans decide. Every component in scope gets expert eyes, not just a tool run.
Zero false positives in the final report. If we can't demonstrate it, we don't waste your engineers' time.
A shared channel with the testers themselves. No account managers, no ticket queues, no lost context.
The same skills we bring to client engagements uncover memory-corruption bugs in one of the most hardened codebases in the world. Recent vulnerabilities we found and reported in Google Chrome:
A crafted HTML page could execute arbitrary code inside the renderer sandbox. Fixed in Chrome 155.0.8059.39.
A crafted HTML page could execute arbitrary code outside the sandbox. Fixed in Chrome 151.0.7922.173.
Out-of-band detection and payload delivery are at the heart of modern exploitation. We operate dedicated, self-hosted infrastructure for both — and make it available to the community.
Capture and inspect every HTTP and DNS interaction hitting your unique subdomain in real time. Craft custom DNS records and responses to confirm blind SSRF, XXE, RCE and data exfiltration.
Spin up fully controlled HTTP responses on your own subdomain in seconds — headers, status codes and body. Built for hosting XSS, CSRF and redirect payloads and for exploiting client-side bugs end to end.
