AI/ML Security
AI systems now call tools, read data and trigger actions. We test the models, agents and permissions behind them.
We test what your AI can do, not just what it says.
What we review.
AI agent security
Agent loops, tool permissions, prompt injection and unsafe actions.
On-chain AI systems
Agents that touch wallets, contracts, transaction builders and oracles.
Model integration security
Model APIs, system prompts, output validation and RAG.
AI supply chain
Data provenance, model artifacts, dependencies and MLOps access.
One instruction. Multiple trust boundaries.
A model can behave as designed and still cause harm through the tools it controls.
Evidence over assumptions.
Five steps, from threat model to verified fixes.
- 01
Scope & threat model
Map the model, tools, data, identities and allowed actions.
- 02
Architecture & trust review
Find trust boundaries and high-impact execution paths.
- 03
Adversarial testing
Probe prompts, context, tools and unsafe action paths.
- 04
Validate exploitability
Reproduce weaknesses and trace their real impact.
- 05
Report & remediation
Findings, root causes and fixes, with optional retesting.
Security for systems that can act.
01. Research-led security.
Adversarial testing grounded in our own AI security research.
02. Follow the action, not just the prompt.
We trace how a manipulated output reaches tools, credentials and transactions.
03. Built from the engineering side.
We build AI security tooling, so we test the whole system, not just the model.
Deliverables, grounded in research.

Why clients trust us.
“Vaultline (formerly 0xTeam) provided us with a comprehensive audit that uncovered critical and hidden vulnerabilities. Their turnaround was fast, and communication was seamless. The team was highly professional and technically sound. We felt secure launching post-audit.”
Playarts Ai@playartsdotai“The audit experience with Vaultline (formerly 0xTeam) was exceptional. Their findings were detailed, accurate, and easy to follow. They identified logic bugs others missed. Our smart contracts are now more robust thanks to their efforts.”
DZap@dzap_io“Working with Vaultline (formerly 0xTeam) was smooth from start to finish. Their security insights helped us fix serious issues early. Their report was thorough, and the post-audit call added great clarity. Definitely our go-to team for future audits.”
Funtoken@funtoken_io“We needed a reliable audit before launch, and Vaultline (formerly 0xTeam) delivered. Their approach blended automation and manual review perfectly. The team was responsive, skilled, and security-focused. We gained major trust from users post-audit.”
AMGI Studios@amgistudios“We loved how hands-on Vaultline (formerly 0xTeam) was during our audit. They didn't just find issues, they educated us too. The report was actionable, clear, and helped our developers level up. Our product is now safer and play-ready.”
