AI agents & copilots
Scoped assistants grounded in your own data, with permissions enforced server-side rather than in a prompt.

Cybrvault builds and secures custom AI systems: agents and copilots, document and workflow automation, and anomaly detection — each shipped with a security review covering prompt injection, data leakage between users, tool-permission scope and model access controls.
Two things are true in 2026: AI can remove genuine hours of work every week, and most AI deployments we review leak data between users or let a crafted document instruct the model. We build the first without shipping the second.
Scoped assistants grounded in your own data, with permissions enforced server-side rather than in a prompt.
Document intake, classification, summarization and routing wired into the tools you already use.
Models that surface fraud, misuse and unusual access across transaction and log data.
Prompt injection, jailbreak, data-leak, tool-abuse and tenant-isolation testing with a remediation report.
Find the workflows where AI actually pays for itself, and the ones where it should not be used.
A working proof of concept on real data within weeks.
Access control, isolation, logging, evaluation harness and red-teaming before production.
Monitoring for drift, cost and abuse, with iteration on real usage.
Real ranges, published up front. Final scope is quoted after a discovery call.
Workflow review, feasibility and prioritized roadmap.
Scales with integrations, data volume and compliance scope.
Prompt injection, isolation and tool-permission testing with retest.
It is a penetration test aimed at the model layer: prompt injection through user content and documents, jailbreaks that bypass policy, data leakage between tenants or users, over-permissioned tools the model can call, and unsafe output handling that leads to XSS or SSRF. Traditional application testing does not cover any of these.
Not in the architectures we deploy. We use enterprise API tiers with training disabled, or self-hosted models where policy demands it, and we document data flow and retention for every integration.
A working prototype on real data typically takes 3-6 weeks. Production hardening — access control, evaluation, logging and red-teaming — adds another 4-8 weeks depending on compliance requirements.
