Security · LLM Firewall

Stop the attack before the model sees it. 

A 2.57ms-p95, 5-layer firewall inspects every request and response — blocking prompt injection, jailbreaks, and data exfiltration in real time. Backed by 249 attack plugins and continuous red-teaming.

The firewall

Five inspection layers. One request path.

Every prompt and response flows through the full pipeline inline — pattern, token, semantic, redaction, and output guardrails — at a 2.57ms p95. No round-trip to a second model, no added hop in your critical path.

01

Pattern & DLP

200+ DLP dictionaries and signature rules catch known injection strings, secrets, and PII before any model spend.

02

Token & Structure

Token-level heuristics flag obfuscation, encoding tricks, delimiter injection, and oversized payloads designed to slip past naive filters.

03

Semantic Intent

A lightweight classifier scores semantic intent — jailbreak framing, role-play coercion, and goal hijacking the regex layer can't see.

04

PII Redaction

Inline redaction rewrites prompts and responses so sensitive data never reaches the provider or your logs — fully configurable per policy.

05

Output Guardrails

Responses are re-scanned for leaked secrets, toxic content, and policy violations before they ever return to your user.

Fail-closed by default. If any layer errors or times out, the request is blocked — never silently passed through. Guardrail bypasses are a security incident, not a fallback.

Proof, not promises

The widest attack coverage in the category — measured.

Every number is sourced from the drift-checked registry and the public firewall benchmark, not a slide. Hover any bar to read the count.

p95 stays flat under load

Full pipeline (pattern · token · semantic · output), measured across 20K runs — while a naive in-band scanner degrades with volume.

Posture

Hardened from the host up.

The firewall protects your traffic; this is how we protect the platform that runs it.

Isolated Infrastructure

Dedicated servers on Hetzner Cloud with full-disk encryption and private networking. No shared multi-tenant compute.

Encryption Everywhere

AES-256-GCM at rest, TLS 1.3 in transit. API keys sealed with envelope encryption — BYOK supported, keys never leave your control.

Least-Privilege Access

Row-level security at the database layer, RBAC for every action, SSH key-only host access, and SSO/SAML with enforced MFA for enterprise.

Continuous Monitoring

Internal health checks every 30s; external synthetic probes every 15 minutes with public history. Sentry error tracking and container monitoring.

Tamper-Proof Audit Log

HMAC-SHA256 audit logging for every data mutation. Append-only, verifiable, and exportable for compliance evidence.

Hardened CI/CD

gitleaks secret scanning as a hard gate, plus SBOM-based vulnerability scanning (syft + grype, daily). No secret reaches main.

Data & compliance

Your data stays yours.

We follow GDPR and ISO 27001 principles, and our SOC 2 control evidence engine is live today. SOC 2 Type 1 attestation is in progress (target Q4 2026, gated on funding the auditor engagement) — the /security page will not claim SOC 2 anything until the auditor's letter is signed.

Automated daily backups (pg_dump at 2 AM UTC) with weekly full-backup verification.

Data residency controls — choose the region your data is stored in.

Right to erasure — full data deletion within 30 days of request.

No training on customer data. Your prompts and evaluations never train a model.

Put the firewall in front of your model.

Route traffic through the gateway and every request gets the full 5-layer inspection — no app changes, no added latency budget you'll notice.
