Stop the attack before the model sees it.
A 3.67ms-p95, 5-layer firewall inspects every request and response — blocking prompt injection, jailbreaks, and data exfiltration in real time. Backed by 300+ 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 3.67ms p95. No round-trip to a second model, no added hop in your critical path.
Pattern & DLP
243+ DLP dictionaries and signature rules catch known injection strings, secrets, and PII before any model spend.
Token & Structure
Token-level heuristics flag obfuscation, encoding tricks, delimiter injection, and oversized payloads designed to slip past naive filters.
Semantic Intent
A lightweight classifier scores semantic intent — jailbreak framing, role-play coercion, and goal hijacking the regex layer can't see.
PII Redaction
Inline redaction rewrites prompts and responses so sensitive data never reaches the provider or your logs — fully configurable per policy.
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.
Why p95 shouldn’t climb with load
Request path, all layers that run on it. The measured point is 3.67ms p95 over 20,000 sequential runs (~388 req/s single-thread); the curve is a projection and the comparison line is a generic in-band scanner, not a named product.
Red-team plugins vs the field
Attack coverage across 100+ strategies and 30 categories.
attack plugins
EvalGuard’s figure is the drift-checked registry. Promptfoo, Garak and PyRIT are theirs, read from their public documentation on 2026-07-22; Garak publishes its probe count as “37+”, plotted here at its floor.
Defense-in-depth breadth
One platform spans the whole attack surface — where a standalone guardrail covers a slice.
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 1.2+ 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 hourly from outside our infra, with the run history available to customers and evaluators on request. Sentry error tracking and container monitoring.
Append-Only Audit Log
Every data mutation is chained into a per-org SHA-256 hash chain, so an edit to a chained row is detectable. Updates and deletes are refused by the database, and the log exports for compliance evidence.
Hardened CI/CD
gitleaks + TruffleHog secret scanning as hard gates, CodeQL static analysis, Trivy container scans, and SBOM-based vulnerability scanning (syft + grype). 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. The SOC 2 audit process begins Q4 2026 — we are not yet under audit, and we will not describe EvalGuard as SOC 2 compliant until an auditor has signed the report.
Automated daily backups — on-box pg_dump at 02:00 UTC plus an offsite encrypted dump at 03:47 UTC, with a restorability check on every dump at 06:00 UTC.
Data residency controls — declare the regions your data may live in; cross-border transfers are evaluated and blocked against that policy.
Right to erasure — your database records are purged on request; trace spans mirrored into the analytics store are not addressable per subject and age out on the platform retention clock instead.
No training on customer data. Your prompts and evaluations never train a model.
50 frameworks mapped · honest posture, no unearned badges
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.
