Security isn't found.
It's forged.
VulnCraft hunts the vulnerabilities others miss — then shows you exactly how to fix them. Deep recon, real exploitation, reports written for humans.
Services
Penetration Testing
Web, API, network and cloud. Manual-first testing that goes beyond scanner output to chained, real-world exploitation paths.
Vulnerability Research
Original research, CVE hunting and responsible disclosure. We publish writeups so the whole community gets sharper.
Security Training
Hands-on labs and workshops for developers and blue teams — learn to break things so you can build them properly.
Bug Bounty Support
Triage help, methodology coaching and report polishing for hunters who want to level up their hit rate.
Secure Code Review
Line-by-line review of critical paths — auth, payments, file handling — with concrete patches, not vague advice.
Incident Readiness
Attack-surface mapping and tabletop drills so the first time you handle a breach isn't during a real one.
