Cantic
Cantic provides an AI-powered penetration testing agent that continuously attacks customer web applications to find, prove, and fix security vulnerabilities. The platform delivers verified exploits with attack replay videos, and on the Fortify plan, sends code fixes as pull requests within 24 hours. Cantic operates under signed rules of engagement with read-only, rate-limited testing tools.

Problem
Traditional penetration testing is slow, expensive, and often reactive, leaving organizations vulnerable to attacks that evolve faster than scheduled security assessments. The rise of AI-powered hacking tools means anyone with a laptop and an AI subscription can now attack web applications, making continuous security testing a necessity rather than an optional exercise.
Solution
Cantic provides an AI agent that performs deep, read-only penetration tests against customer domains every day, working through attack surfaces the way a real attacker would. The agent maps the full perimeter and systematically tests for OWASP Top 10, API Top 10, CWE/SANS 25, business logic flaws, and chains of findings that combine multiple vulnerabilities. Every discovered issue comes with a working exploit and an attack replay video, eliminating false positives and showing exactly how the vulnerability was exploited. The platform requires no installation—customers simply submit their domain and receive first results in under an hour. Scans are rate-limited, sandboxed, and use read-only tools that cannot modify, delete, or exfiltrate data from tested applications. Reports include copy-paste remediation guidance specific to the customer's technology stack, and can be exported as PDFs for compliance purposes. The service requires authorization verification via DNS record, corporate email sign-in, or direct Cantic approval before any scan runs. On the Fortify plan, Cantic delivers fixes as pull requests within 24 hours and verifies the fix by attacking again.
Target Audience
Primary customers are businesses and developers who own or operate web applications and need continuous, verified security testing without the cost and delay of traditional penetration testing engagements.
