Koreshield

The problem Koreshield is built around is prompt injection through trusted context: a poisoned CRM note, a malicious ticket attachment, or a retrieval result that inherits system-level authority it was never meant to have. The tool scans three boundaries independently — the raw customer message, the retrieved context passed to the model, and the tool calls the model proposes — and records a structured decision for each. The integration is API-first: you create a server-side scan key, point your workflow at the FastAPI security service backed by PostgreSQL, and begin receiving decisions before you block anything.

The defining architectural choice is detect-before-enforce. The vendor describes a staged rollout: observe live traffic without interrupting it, review the evidence log for misses and false positives, and only enable enforcement once you understand what the fallback behavior looks like when a request is stopped. This makes the evaluation period auditable rather than speculative — you can show stakeholders exactly what the tool caught and what it missed against real production traffic before any policy takes effect.

Koreshield fits teams moving AI support workflows from internal testing into environments where a bad decision has compliance or customer-facing consequences. The docs describe it as a complement to existing authorization systems, not a replacement — a distinction that matters for regulated workflows where access control and threat detection need to stay separate. The ceiling appears when your inputs include files or images: the vendor states the tool does not inspect arbitrary files or images at this stage, which means teams with those vectors need a parallel scanning solution or must exclude those input types from coverage.

Deployment runs as a FastAPI service with PostgreSQL, connected to from a hosted console or your own support infrastructure. The API is available for server-side integration, and the scan key model keeps security decisions server-side rather than inside client code. Teams evaluating the tool start with a no-card evaluation period before any enforcement decisions are made.
