Infiltra.ai - Autonomous Web Application Penetration Testing Platform

Infiltra.ai is redefining penetration testing for modern application security. Traditional pentesting is slow, manual, and point-in-time. Modern applications ship weekly, sometimes daily. That gap creates risk. Infiltra.ai closes it. Our AI-powered platform continuously tests web applications and APIs using autonomous agents that behave like real attackers, not just vulnerability scanners. We don’t just identify vulnerabilities. We exploit them, validate real impact, and provide clear remediation paths. What makes Infiltra different • Autonomous attack simulation Agents chain exploits, escalate privileges, and validate real-world risk • Continuous security testing Run on-demand, scheduled, or embedded directly into CI/CD pipelines • Exploit validation (not noise) Every finding is backed by evidence. No false positives, no guesswork • Full-stack coverage Deep testing across web apps, APIs, authentication flows, and business logic • Instant retesting Validate fixes immediately with delta scans. No more waiting weeks for retesting services or just trusting that the team has done it. Built with modern teams in mind, Infiltra empowers: • Security teams to reduce risk and prioritise what matters • Developers to test early and often without bottlenecks • Organisations to move from annual audits → continuous assurance Security shouldn’t slow you down. It should keep up. Test continuously. Validate real risk. Ship with confidence.

Vector

Vector is an autonomous pentester. Point it at your web app and our AI agents safely attack it the way a real hacker would, then hand back every weakness they found, proof that each one is exploitable, and the exact fix. It's simple to use, with no security background needed. You get an attacker's view of your app for a small fraction of the price and time. Most software shipped today has holes the people who built it never see. Vector finds them before someone else does.
