Your LLMs Are
Being Attacked.
Most Don't Know.

Your security team knows OWASP Top 10. Your AI team knows the model. Nobody owns the gap between them — that's where attacks land. NuvynAI tests the layer both teams miss.

🛡️
Guardrail API
Real-time Threat Detection

A production-ready security layer that sits between your users and your LLM. Built against the OWASP LLM Top 10 — the threat list your standard security team was never trained on. Catches what commercial guardrails miss.

  • Prompt injection & jailbreak detection
  • RAG poisoning & context bleed prevention
  • Model extraction attempt blocking
  • PII leakage interception before model exposure
  • Sub-50ms overhead — any stack, any model
  • 25+ threat patterns, 65 tests passing in production

NuvynFlow
Secure Agent Orchestration

AI workflow automation with security built in from the start — not bolted on after an incident. Purpose-built for teams running agents across internal systems where a single compromised step cascades downstream.

  • Orchestrate agents across your entire operation
  • Intelligent model routing — right model, right task
  • Audit trail on every agent decision
  • GDPR-compliant data handling & deletion
  • Capability confinement — agents can only do what you allow
  • Real-time Slack alerting on anomalous behaviour

C4
DevOps Governance

The governance layer for engineering teams shipping with AI-assisted development. C4's security gates are modelled on Claude Code's native hook architecture — PreToolUse intercepts before execution, exit code 2 blocks the operation entirely. Enforcement at the tool-call level, before anything reaches your codebase.

  • Pre-execution interception on every AI tool call
  • Token usage tracking & team spend controls
  • Automated quality gates on AI-generated output
  • Full session audit trail for compliance
  • CI/CD pipeline integration — security in the workflow

Catch Attacks in Real Time.

Enter a prompt below. NuvynAI routes it to both Claude and Gemini simultaneously — secured, monitored, and intercepted in real time. Try a prompt injection. Try a jailbreak. See what gets caught.

01
Found gaps Lakera Guard missed
Our ARIA testing framework identified contextual obfuscation attacks that bypass leading commercial solutions — including 0% detection on ML model extraction via legitimate-sounding prompts.
02
Built on real threat research
The 9-check framework covers all OWASP LLM Top 10 vectors simultaneously. Not a generic scan — specific to your product, your model, and your threat model.
03
Assessment = commercial asset
A written security posture report gives you something concrete to show enterprise clients during due diligence and investors during raise conversations. It pays for itself before the first client meeting.
04
Deployed in 90 days, concept to production
Every NuvynAI product is live and accessible — not pitch decks. The Guardrail API is running on real infrastructure right now. That execution speed transfers to every client engagement.

Three Ways to Work
With NuvynAI

🔍
Rapid Security Assessment

A systematic 48-hour assessment of your LLM deployment against the full OWASP LLM Top 10. We run 65 attack vectors against your live endpoints, identify what your stack is vulnerable to, and deliver a written report with severity-rated findings and a prioritised remediation roadmap — something concrete you can show a CTO, CISO, or enterprise client.

🛡️
AI Firewall Testing

Already running Lakera, AWS Bedrock Guardrails, or another AI firewall? We test it the way attackers do — with contextually obfuscated prompts, multi-turn manipulation, and domain-specific attack vectors your firewall has never seen. You get a gap analysis and vendor-agnostic recommendations grounded in real adversarial findings, not benchmarks.

⟶ Full adversarial testing in 3 days

📡
Ongoing Security Retainer

AI systems evolve fast. New models, new endpoints, new agent capabilities — each one a new attack surface. A monthly retainer keeps your security posture current as your product changes. Includes monthly audits, threat intelligence briefings, quarterly red team exercises, and priority access for incident response when something unexpected lands.

⟶ Continuous coverage, monthly cadence

How It Works

From First Call to
Secured Deployment

01
Discovery Call

30 minutes. We map your LLM stack, identify your highest-risk surfaces — inference endpoints, RAG pipelines, agent integrations — and scope the engagement precisely. No sales pitch. Technical from minute one.

02
Threat Assessment

48-hour systematic testing using the 9-check framework against all OWASP LLM Top 10 vectors: prompt injection, data extraction, jailbreaking, RAG poisoning, model extraction, PII leakage. Run against your live endpoints.

03
Written Report

Severity-rated findings, proof-of-concept exploits for each vulnerability, and a prioritised remediation roadmap. A document you can share with your board, enterprise clients, or legal team. No vague recommendations.

04
Remediation Support

Optional hands-on implementation of fixes — including Guardrail API integration for ongoing protection. Verified re-testing confirms each finding is resolved. You leave with a clean posture document, not just a to-do list.

Built by a Practitioner,
Not a Consultant

We found what Lakera Guard missed

Our ARIA testing framework exposed a 0% detection rate on ML model extraction via contextually obfuscated prompts in Lakera Guard. This is the research your next vendor won't tell you about.

The gap nobody owns — we own it

Your security team tests OWASP Top 10. Your AI team knows the model. Neither knows adversarial LLM behaviour at scale. That gap is where prompt injection, PII context bleeds, and jailbreaks land. That's exactly what we test.

Products in production, not slides

The Guardrail API is live. NuvynFlow is deployed. 65 tests passing. The same execution speed and production discipline that built our products applies to every client engagement.

Security is a commercial accelerator

Enterprise clients run due diligence on your AI stack. Investors ask about AI risk. A clean written security report isn't just a technical artefact — it's a sales asset that removes blockers and shortens deal cycles.

# Finding 3 bypassed Lakera Guard. We caught it.

Heard Before.
Answered Honestly.

"We already have a security team."
Do they test OWASP LLM Top 10? It's a different list from the one they're trained on. We test the layer between your model and your users — not a replacement for what they do.
"We're not ready to prioritise this yet."
When the first enterprise due diligence request lands, the timeline compresses fast. A rapid assessment now gives you a written security posture document before you need it — not after.
"How is this different from Lakera or other tools?"
Most tools cover one layer. We found a 0% detection rate on ML model extraction in Lakera Guard via contextual obfuscation. We run all 9 checks simultaneously, specific to your stack.
"We're too early-stage for this."
Retrofitting security into a shipped product costs 10x what building it in costs. A rapid assessment now is a commercial asset — something you can show investors and clients immediately.
