- Identify and reduce exposure from unmanaged AI use, public agents, exposed credentials, risky integrations, insecure plugins, and over-permissioned identities.
- Assess AI applications, copilots, agents, models, retrieval systems, prompts, data sources, and third-party services through security reviews and threat modelling.
- Implement guardrails for identity, access, secrets, data handling, connector security, logging, monitoring, permissions, and human oversight.
- Maintain clear ownership, risk classification, findings, and remediation tracking, communicating progress to technical teams and senior stakeholders.
Who you are
