CORSy is a free security scanning tool. Halo Security Server Scanning is a commercial security scanning tool by Halo Security. Compare features, ratings, integrations, and community reviews side by side to find the best security scanning fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
DevSecOps teams scanning third-party APIs and SaaS integrations will get the most from CORSy because it catches CORS header misconfigurations that let attackers bypass same-origin policy restrictions; most teams never audit this attack surface until it causes a breach. The tool is free and command-line native, which means it fits into CI/CD pipelines without licensing friction or vendor lock-in. Skip this if you need a GUI, reporting dashboards, or coverage beyond HTTP header analysis; CORSy is deliberately narrow and won't replace a full web application scanner.
Startups and SMBs that need visibility into external-facing infrastructure without managing agents should start with Halo Security Server Scanning. The agentless model means you're scanning production servers within minutes of signup, and the real-time Slack alerting actually gets findings in front of the right person before they disappear from memory. This tool prioritizes detection over remediation tracking, so teams expecting tight ticketing integration or drift remediation will need to bolt on a separate system.
