The tooling is the product. The engagements are how it gets sharp.
Principle Breach is the security practice of Adversary Holdings Private Limited, incorporated December 2025. It exists because most security work stops at the list of things that might be wrong, and the useful part starts after that.
The work runs in two directions. We publish vulnerability research on software other people depend on, and we run scoped offensive engagements against systems companies own. What the agents learn doing either goes back into the agents.
“Assume it is broken until someone has tried to break it. Hope is not a control, and a finding nobody can reproduce is not a finding. The exploit is the argument.”
The record is public. Read it before you talk to us.
What we publish
Vulnerability research on software in wide use, disclosed as CVEs with technical writeups. Every disclosure carries a CVE identifier and a vendor advisory you can verify without asking us.
How an engagement runs
Scope agreed in writing, then a time-boxed window against named objectives, worked by agent swarms. Findings arrive already proven, with the evidence attached and a walkthrough for the engineers who own the fix.
How we disclose
Vendors are contacted before anything is published and given time to ship a fix.
The work is deliberately narrow.
Offensive testing against applications, cloud and identity, reported in terms an engineering team can act on and a board can understand. Nothing else is sold here.
Capabilities
Red Team Engagements · Penetration Testing · Insider Threat Simulation · Breach Simulation · Security Consulting
Agents do the work. A human is accountable for the answer. Swarms enumerate, exploit and chain in parallel across the whole surface, at a breadth no human window has room for. A human sets the objectives, decides which reached states actually matter, and signs the report.
Reference Frameworks
MITRE ATT&CK · OWASP Top 10 · OWASP Testing Guide · PTES
Nothing is committed before it is scoped.
Send the system and the outcome you are worried about. You get back a scope, a timeline, and what the engagement will not cover.
