Find your AI's weaknesses
before attackers do
Scan your API surface free in seconds, just enter a URL, no key required. Then request a managed red team assessment: 173 adversarial attacks across 25 modules, with LLM-as-judge scoring and compliance mapping across 9 frameworks including ISO 42001, EU AI Act, HIPAA, and HITRUST.
Free to scan your API surface, managed when you go deeper
The free scan inspects your API layer passively, the same requests a browser already makes. No API key, no account, nothing stored. You see your security posture across 13 checks in seconds.
When you need adversarial LLM testing, our team runs it for you. You never enter credentials, we verify authorization, configure your endpoint, and deliver the results. Nemesis tests how your AI layer responds to attacks, not your website, infrastructure, or code.
When McKinsey's AI was breached in March 2026, it wasn't through exotic hacking. An autonomous agent spent $20 and two hours sending crafted prompts and walked out with 46.5 million internal messages. Nemesis checks whether yours would do the same.
Run a free passive scan
Enter a URL, no account, no API key. Nemesis inspects your API surface with 13 passive checks: TLS, security headers, CORS, cookie flags, HTTP methods, and more. Results appear instantly, and nothing is stored.
Review your risk score and findings
Every check is shown with a pass, fail, or info result, what it tests, the evidence, and a concrete remediation step, mapped to the OWASP API Top 10 and NIST SP 800-115.
Request a managed assessment
For deeper testing, request an API Recon scan or a full Red Team assessment. Our team verifies authorization, configures your endpoint, and runs the engagement, so you never touch credentials yourself.
Receive your compliance report
A full Red Team assessment fires 173 adversarial attacks across 25 modules with LLM-as-judge scoring. You receive an executive report with severity ratings, OWASP references, remediation guidance, and compliance mapping across 9 frameworks: NIST AI RMF, MITRE ATLAS, ISO 42001, ISO 27001, EU AI Act, HITRUST, SOC 2, HIPAA, and NIST 800-53.
Built for anyone deploying or securing AI
If your product, team, or organisation uses a large language model, you have an attack surface that needs testing.
Developers building AI products
Shipping a chatbot, AI assistant, or LLM-powered feature? Test it before your users - or an attacker - do. Paste your system prompt and find out what breaks before it goes live.
Enterprise AI teams
Running an internal AI platform or RAG-powered tool? Verify your system prompt defenses and data handling before your next compliance audit.
Security engineers & red teamers
Add LLM-specific attack coverage to your toolkit. Every test maps to OWASP LLM Top 10 and NIST 800-53 so your findings slot directly into existing security workflows.
Researchers & students
Learn AI attack techniques hands-on with real prompts against real models. Each module has a plain-English explanation, a real-world incident, and remediation guidance.
Compliance & risk teams
Generate audit-ready evidence that your AI systems were tested against OWASP LLM Top 10. Every report includes NIST 800-53 Rev 5 control references.
No account, no cost, no lock-in
Bring your own API key. No sign-up required. No data stored. 20 attack modules, 134 tests, 8 compliance frameworks including ISO 42001, EU AI Act, HIPAA, and HITRUST.
Built to OWASP & NIST 800-53 Rev 5
We apply the same security standards to this tool that we test for in yours.
No credentials for the free scan
The free passive scan takes only a URL. No API key, no account, no credentials of any kind. For managed assessments, our team handles any required access under written authorization, so you never paste a credential into a form.
No scan persistence
Free scan results are generated and rendered in your browser. When you close the tab, everything is gone unless you downloaded the report yourself.
Authorization-gated testing
Free scans inspect only your own URL passively. Managed assessments begin only after our team verifies written authorization for the target, so testing never runs without a legally meaningful sign-off.
OWASP Top 10 hardened
CSP headers, input sanitization, XSS prevention, parameterized queries, and rate limiting per IP. This application defends against the same vulnerabilities it tests for.
NIST 800-53 Rev 5 aligned
AC-2 account controls, AU-2 metadata-only logging, SC-28 no sensitive data at rest, and SI-10 input validation on all fields.
Kyora IQ Nemesis is provided strictly for authorized security research, education, and testing of AI systems you own or have explicit written permission to assess. By using this tool, you confirm you hold that authorization. The operators store no credentials, scan results, IP addresses, or personally identifiable information and accept no liability for unauthorized, unlawful, or malicious use. All attack requests are executed using your own API credentials directly from your browser against your designated endpoint only. Use against systems without authorization may violate the Computer Fraud and Abuse Act (CFAA), the UK Computer Misuse Act, GDPR, and equivalent laws in your jurisdiction. You are solely and entirely responsible for ensuring lawful use. Full responsible use policy →
