Test real web application behavior at runtime
Ostorlab’s DAST scanner monitors how your web application and APIs behave during execution, uncovering exploitable runtime vulnerabilities that traditional scanning misses.
Detect exploitable vulnerabilities at runtime
Simulate real-world attacks against your live web app or backend API without access to source code to uncover SQL injection, XSS, broken authentication, misconfigurations, insecure endpoints, and more.
Leverage AI-driven scanning and prioritization
Ostorlab’s proprietary AI learns your web application behavior, authenticates through complex sessions, and validates exploitability, delivering concise, accurate findings with runtime evidence to reduce noise and improve focus on real risks. AI-agent findings also come with a working proof of concept.
Explore applications dynamically with AI Monkey Testing
Ostorlab’s AI-powered Monkey Tester continuously interacts with your web application, generating realistic and unexpected user actions to uncover hidden execution paths, logic flaws, and exploitable runtime vulnerabilities that traditional crawling misses.
Ostorlab’s Web DAST Features
Discovery & Crawl
Automatically maps your live web application, APIs, and exposed endpoints to model the attack surface based on actual runtime behavior.
Attack Simulation
Performs black-box testing that mimics real attacker techniques against your web application and its communications, without needing access to source code.
AI-Enabled Prioritization
Uses machine reasoning to validate findings, confirm exploitability, and prioritize real risks while significantly reducing false positives.
Remediation Guidance
Provides actionable, contextualized findings with runtime evidence, plus a working proof of concept for AI-agent findings, to help developers understand, reproduce, and fix vulnerabilities quickly.
Authenticated Scanning
Scans your web application while logged in: login and password, HTTP headers, certificates, recorded Chrome/Puppeteer scripts for multi-step or SSO logins, and SMS, email or TOTP one-time codes once a test account is set up, so vulnerabilities behind authentication are tested, not ignored. The same authentication support applies to mobile app scans.
