Masking runs over HTTPS to apply detection; audit defaults to metadata only — decisions, tool names, counts, not raw prompts. For stricter control, run the ingress sidecar in your VPC so enforcement stays inside your network.

Blekline can mask or block at ingress (prompts, tool args) and redact on the return path before your agent consumes the response. You get a defensible allow/mask/block record per interaction, not just a post-hoc alert.

No rip-and-replace. Wire one path — MCP proxy, SDK, or ingress gateway — and expand from there. Open-core packages let security review the code while engineering keeps shipping.

Yes — if you scope it correctly. Blekline logs policy outcomes at the agent boundary with exportable metadata. It supports your controls; it does not replace your RoPA, DPIA, or lawful-basis analysis.

Standard DPA, published subprocessors, and privacy documentation for diligence. EU residency and VPC deployment are available on enterprise terms. Default SaaS is US-hosted — flag that in your transfer assessment.

Masking operationalizes minimization at execution time. You still own what counts as personal data, retention, and high-risk AI obligations under the EU AI Act. Blekline is the control layer; legal judgment stays with you.

Risk control. You are buying governed agent execution — enforceable policy and audit evidence — not another seat on ChatGPT. Price it like security infrastructure, not like an AI subscription.

One production workflow with measurable outcomes: entities masked, tools blocked, violations logged. Enough to justify platform spend or kill the bet before a multi-year commitment.

In-house means MCP enforcement, policy streaming, audit schema, and multi-vendor ingress — quarters of eng time on non-differentiating work. Blekline compresses that to weeks with evidence your board can read.
