Facts read 19 Sep 2026 – 15 Oct 2026
Choosing a web application security scanner starts with the parts of an application you need to examine. Compare API scanning and JavaScript crawling with authenticated scans to see which scanning approaches matter to your work. Scheduled scans and compliance reports add context for recurring assessment and reporting, while deployment and target limit can affect operational fit. Free-plan availability and paid-from pricing help frame cost. ImmuniWeb, Nuclei, and Beagle Security are among the named options, alongside Qualys External Attack Surface Management and ZeroThreat. Weigh the listed coverage and constraints against the sites and APIs you need to assess.
