Test the system around the model

A secure prompt alone does not enforce access control. We assess the application and connected services that determine what an AI feature can retrieve, invoke, and disclose.

  • Prompt injection paths through user content, documents, and retrieved sources
  • Tenant and user authorization for retrieval, memory, and generated answers
  • Tool and MCP permissions, approval boundaries, and high-impact actions
  • Secrets, sensitive output, logging, and data retention across the AI workflow

Agent identity and tool-call testing

For agents that use connectors or service accounts, we trace the effective identity at each hop. Testing checks whether the destination independently enforces the original caller’s permissions and whether read or write tools exceed their intended scope.

  • Map caller, agent, connector, service identity, and destination API
  • Use synthetic records to verify cross-user and cross-tenant denial
  • Check that consequential actions require the intended approval
  • Confirm logs capture the caller, execution identity, target, decision, and result

Singapore delivery for AI products

We scope against the deployed product, its data flows, model providers, and integrations. Where useful, technical findings can support internal risk and control mapping for Singapore operations; the assessment does not represent regulatory approval.

  • Start with architecture, data classification, and authorized test accounts
  • Test staging or isolated tenants first and agree production safeguards
  • Prioritize fixes by demonstrated access and business impact
  • Retest the specific boundary that failed after remediation

Frequently Asked Questions

How long does the AI & LLM Security process take?

Typically 1-4 weeks depending on scope and infrastructure complexity. We provide a firm timeline after discovery.

What do the deliverables look like?

Each finding includes exploit proof (PoC), business impact score, and developer-friendly remediation code — plus an executive summary.

Can the report support internal review or audit preparation?

Yes. Our reports are prepared as technical evidence packages and remediation records that can support internal review and audit-readiness workflows.
