█A scanning service built on Claude Mythos AI
We are a purpose-built security scanning service that uses Claude Mythos as its reasoning engine.
AI reasoning, not pattern matching
Mythos Scanner uses Anthropic's Claude Mythos to reason about your application's logic, data flows, and trust boundaries, not just fire known-bad payloads. It finds vulnerabilities that signature scanners can never catch.
A service, not a raw AI API
Mythos Scanner is a dedicated vulnerability scanning service built on top of Claude Mythos. We handle attack surface mapping, probe orchestration, exploitability validation, and structured report generation, you just enter a URL.
Structured security reports
Every scan delivers an executive summary, full technical findings with CVSS scores, and developer-ready remediation steps, formatted for both stakeholders and engineers. Not raw AI output you have to interpret yourself.
Flat, predictable pricing
Using the Claude API yourself would cost you per token for every scan. Mythos Scanner offers simple per-scan pricing, no token math, no surprise API bills, no engineering overhead to replicate what we've already built.
Built for reasoning,
not pattern matching
Mythos Scanner uses Anthropic's Claude Mythos as its core reasoning engine. Unlike traditional scanners that fire known-bad payloads against a signature library, Claude Mythos reasons about your application's architecture, data flows, and trust boundaries to surface vulnerabilities that rule-based tools consistently miss.
This is the difference between a tool that asks “does this response match a known-bad pattern?” and one that asks “what would a skilled attacker try here, and what would success look like?”
Mythos Vulnerability Scanner wraps Claude Mythos in a complete scanning service, attack surface mapping, probe orchestration, exploitability validation, and structured reporting. Join the waitlist to get early access.
Join the WaitlistClaude Mythos is the reasoning engine
Anthropic's Claude Mythos AI reasons about your application the way a security researcher does, modeling attacker intent, analyzing application context, and validating exploitability at each step.
We built the scanning layer on top
Mythos Scanner handles attack surface crawling, probe generation, response analysis, and report formatting, so Claude Mythos can focus on the security reasoning it's designed for.
Exploitability validation, not just detection
Every finding is validated for real exploitability in your application's specific context before it appears in your report. Fewer false positives, more signal.

Security scanning that actually thinks
The Claude Mythos AI powering Mythos Scanner doesn't just match patterns. It reasons about your application the way a senior security researcher would, and Mythos wraps that intelligence in a purpose-built scanning pipeline.
Anthropic Claude Mythos Engine
Powered by Anthropic's most advanced security reasoning system. Claude Mythos understands application context at a level no other AI model can match, reasoning through attack chains the way the world's best researchers do.
Deep Application Awareness
Mythos maps your application's full attack surface, endpoints, data flows, authentication boundaries, before running a single test.
Continuous Scanning
Integrate with your CI/CD pipeline and catch vulnerabilities before they reach production. Shift security left without slowing down deployments.
OWASP Top 10 Coverage
Full coverage of OWASP Top 10, SANS 25, and CWE categories. Plus emerging threat vectors specific to modern web architectures.
Zero False Positives (Goal)
Claude Mythos validates every finding before reporting. Our AI confirms exploitability in context, so you fix real issues, not noise.
Developer-Friendly Reports
Findings come with line-level code references, remediation examples, and severity-ranked priority lists. Ship fixes, not confusion.
Reports you can actually act on
Every Mythos scan delivers a complete security report, written for humans, not machines. Non-technical executives and senior engineers both get exactly what they need to understand and fix every finding.
Executive Summary
Non-Technical3 critical vulnerabilities found. Immediate remediation recommended. SQL injection in /api/users endpoint poses serious data breach risk.
Critical Findings

Executive Summary
Plain-English overview of your security posture, written for stakeholders and non-technical leadership. Risk score, key risks, and business impact explained without jargon.
Full Technical Findings
Every vulnerability with CVSS score, affected endpoints, request/response evidence, and Claude Mythos's reasoning for why it's exploitable in your specific application.
Priority-Ranked Fix List
AI-ranked by real-world exploitability and business impact, not just CVSS scores. Know exactly what to fix first so your team's effort goes where it counts.
Step-by-Step Remediation
Concrete, actionable steps to fix every finding. No vague advice, specific instructions your developers can implement immediately without needing security expertise.
Code-Level Fix Examples
See exactly what the vulnerable code looks like, and exactly what it should look like after the fix, in your framework and language.
Verification Guidance
After applying fixes, know how to confirm each vulnerability is fully resolved. Includes test cases and what to check on your next scan.
Every attack vector,
covered
From classic injection attacks to modern API vulnerabilities and business logic flaws, Mythos covers the full spectrum of web application threats, powered by Anthropic's Claude Mythos reasoning engine.

MediumClaude gives you answers.
We give you security.
You could try to replicate what we do with the standard Claude API , but you'd be spending weeks of engineering time to get a fraction of the result. Here's why security teams choose Mythos instead.
Structured Security Reports, Not Chat Responses
Asking Claude directly gives you raw text. We give you a professionally structured security report, executive summary, severity rankings, technical details, and step-by-step remediation in a format your team can act on immediately.
Built by Security Experts for All Audiences
Our report format was designed by certified penetration testers and AppSec engineers to serve both non-technical stakeholders and senior developers simultaneously, every section written for its audience.
No Token Fees: One Flat Price
Using the Claude API directly means paying for every input token of scanning context, costs spiral with large codebases. We offer simple, predictable per-scan pricing. No token math, no surprise bills.
Purpose-Built Scanning Intelligence
We've invested thousands of hours engineering the attack surface mapping, vulnerability validation logic, and scanning prompts. You'd need significant security expertise and engineering time to replicate even a fraction of this.
Just Enter Your URL
No prompt engineering. No security expertise required to get started. Enter your URL and we handle everything, attack surface mapping, vulnerability testing, and full report generation, automatically.
Purpose-Built Scanning Infrastructure
We've built the attack surface crawling, probe orchestration, exploitability validation, and report generation layer on top of Claude Mythos. You get all of that out of the box, just enter a URL.
