AI governance, made verifiable

Your AI drifts.
Oethos catches it — before your users do.

A model-agnostic integrity layer for enterprise AI. It flags value drift, sycophancy, and identity slippage in real time, and records every interaction to a tamper-evident audit trail. Runs alongside OpenAI, Anthropic, Google, or your own models — in shadow mode first, so you measure before you enforce.

The gap

Content filters catch slurs. They miss the failures that actually cost you.

Sycophancy

Your AI tells users what they want to hear — agreeing with a bad decision, softening a real risk, flattering instead of informing. The most damaging answers are often the most agreeable ones.

Drift

Over a long session the model quietly departs from your values and tone. The second reply is on-brand. The fortieth isn't.

Identity slippage

It stops sounding like you — and starts sounding like a generic assistant, or worse, like your competitor.

None of these trip a toxicity filter. All of them erode trust, brand, and — under the EU AI Act, ISO 42001, and the NIST AI RMF — your compliance posture. See seven real verdicts from our validation set →

What Oethos does

Five checks on every substantive response.

A separate evaluator with your ethics at position zero — fresh context on every call, so the standard never fades with conversation length.

Why it's different

Not another content filter.

Beyond content safety

Most guardrails ask is this harmful? Oethos asks is this still you? — the question that protects a brand, not just a content policy.

Independent & cross-model

Your cloud provider's guardrails only cover their own models. Oethos governs every vendor you use, from the outside — one standard, applied consistently.

Fail-closed & provable

When the evaluator can't reach a confident verdict, it holds the response rather than waving it through. Every verdict lands in a hash-chained audit trail you can independently verify.

How it works

Live in three steps. Invisible in production.

A transparent proxy. No rebuild, no rip-and-replace.

  1. Point your API calls at Oethos. A transparent proxy — no rebuild required.
  2. Configure your values and policies. Per department, with adjustable sensitivity.
  3. It runs in the background. Shadow mode first (observe, never block), then active enforcement when your numbers say you're ready.
Built to be audited

Governance you can hand to a regulator.

  • Fail-closed by default — a malfunctioning evaluator holds; it never silently approves.
  • Tamper-evident audit log — hash-chained, so any alteration is detectable.
  • Shadow-mode rollout — measure impact before you enforce anything.
  • PII redacted before it leaves your perimeter.
  • Reproducible validation report — available under NDA.
  • Model-agnostic — OpenAI, Anthropic, Google, or your own.
The foundation

Most AI serves hidden values. Yours shouldn't be a mystery.

Every model is trained on somebody's values — usually undisclosed. Oethos makes the standard explicit, written down, and yours to configure. Our default framework rests on a simple, demanding idea: protect the good, proactively — treat people as ends, never as metrics to optimize. Adopt it, adapt it, or replace it with your own.

Regulated & brand-sensitive enterprises

Finance, healthcare, legal, insurance — where an off-standard answer is a liability, not just a bad look.

Values-driven organizations

Including faith-based institutions — that want their AI to hold a stated standard, not an accidental one.
