Intruder vs ShadowSecurityScanner

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.

ShadowSecurityScanner is a free, open-source desktop tool for penetration testing and network vulnerability scanning on Windows, macOS, and Linux. It scans network hosts, servers, web applications, and network appliances using port checks, service and operating-system fingerprinting, and thousands of active security tests. Findings receive FIRST.org EPSS scores and are checked against the CISA Known Exploited Vulnerabilities catalog. Scan comparisons identify findings that are new, regressed, or resolved. Reports can be exported as PDF, HTML, SARIF, XML, or CSV, with SARIF described as suitable for GitHub code scanning. A signed update feed refreshes the audit catalog with daily CISA KEV updates, Nuclei, and curated advisories. The application runs locally, stores its database in the user profile, and has no cloud component or telemetry. It is distributed as one self-contained app, without agents or a database server. Listed requirements include Windows 10/11, macOS 11 or later on Apple Silicon, and Linux x64 or ARM64. Use is limited to authorized testing; denial-of-service tests are excluded.
