In their own words
Intruder
Intruder provides continuous vulnerability scanning for infrastructure, web applications, APIs, and cloud environments, with issue prioritization and remediation guidance. It ranks issues using exploit likelihood and real-world threat intelligence, while emerging-threat scans check systems within hours of new risks appearing. Cloud scans assess AWS, Microsoft Azure, and Google Cloud environments for vulnerabilities, misconfigurations, and exposures. Authenticated dynamic application testing covers customer-controlled web apps and APIs, including OWASP Top 10 checks. Supported targets also include external IP addresses, domains, subdomains, internal Windows, macOS, and Linux devices, and container images. Integrations include cloud platforms, code hosts, issue trackers, chat services, Vanta, and Drata. Its API can manage targets, view issues, start scans, and retrieve results. A free plan and 14-day trial are listed. The free plan covers five infrastructure targets and weekly external scans, but does not include web apps. Internal target scanning is available only on Pro and Enterprise plans. All customers receive live chat support.
