Boundary Guard

The runtime trust layer for production agents. Boundary Guard gives agents and operators a deterministic checkpoint before ingestion, memory writes, tool chaining, CRM enrichment, database persistence, or irreversible actions. Before your agent acts, run Boundary Guard.

Risk Scan

Detect prompt injection, secret leakage, and PII-like strings before trust.

JSON Extract

Extract valid JSON from prose, markdown, or malformed model output.

Schema Normalize

Normalize untrusted structured data into a stable schema contract.

PII Redact

Redact emails, phones, and secret-like tokens before logs, storage, or sharing.

Contact Extract

Pull emails, phones, URLs, and domains from messy text or scraped content.

Text Chunk

Split long text into deterministic overlapping chunks with hashes for RAG and ingestion.

Guard / Boundary Receipt

Run the full boundary pass and return a deterministic Boundary Receipt.

Why buyers use it

RAG and ingestion hygiene

Chunk long text, scrub sensitive values, and normalize fields before the first vector write or database insert.

Lead and contact capture

Extract emails, phones, URLs, and domains from messy text or scraped pages before sales agents and CRMs touch the data.

Trust before action

Run Risk Scan or full Guard before tool calls, memory updates, or customer-facing automation so risky payloads stop early.

Cheap enough to run everywhere

Every paid endpoint is priced at $0.01 / call so teams can afford to insert Boundary Guard into every critical handoff.
