DYNAMIC APPLICATION SECURITY TESTING
DAST that tests your running app the way attackers do
Authenticated scanning of your web apps and APIs, run in CI or on a schedule, with every finding validated by an analyst.
What is DAST (Dynamic Application Security Testing)?
Dynamic Application Security Testing (DAST) tests a running web application or API from the outside, the way an attacker would, by sending crafted requests and analysing the responses. It finds runtime issues such as injection, misconfigurations and authentication flaws without needing access to source code.
Code can look safe and still run unsafe.
Misconfigured servers, missing headers and flaws that only appear at runtime slip past code scanners. DAST attacks the running app, and HostX analysts validate the results so your team fixes real, reproducible issues.
