Web-Check

Web-Check is a powerful open-source intelligence (OSINT) tool created by Alicia Sykes for conducting comprehensive analysis of any website's infrastructure, security configuration, and technology stack. With over 29,000 GitHub stars, Web-Check has become a trusted resource for security researchers, penetration testers, developers, and site owners who need deep visibility into web properties. By entering a domain, users receive extensive intelligence across 50+ analysis modules covering DNS records, IP geolocation, SSL certificates, security headers, open ports, technology identification, performance metrics, and historical data. Web-Check aggregates information from multiple sources into a single dashboard, eliminating the need to run dozens of separate tools and providing actionable insights for security auditing, competitive analysis, incident response, and infrastructure reconnaissance.

Common Use Cases

Security Professionals & Penetration Testers: Conduct reconnaissance during security assessments, identify potential attack vectors through port scanning and service enumeration, analyze SSL/TLS configurations for weaknesses, assess security header implementations, and detect exposed services or misconfigurations. Web-Check accelerates the initial reconnaissance phase by automating dozens of manual checks and presenting a comprehensive security posture overview. DevOps Engineers & Site Owners: Audit your own infrastructure to identify security gaps, verify DNS configurations, validate SSL certificate chains, check security header implementations, analyze technology stacks, and monitor for exposed services. Use Web-Check as part of security review processes to ensure configurations meet best practices and compliance requirements. Threat Intelligence Analysts: Investigate suspicious domains during phishing investigations, build infrastructure profiles of threat actors, identify relationships between domains through shared hosting or technologies, check domains against malware blocklists, and gather evidence for incident response. Competitive Intelligence & Business Analysts: Discover competitors' technology choices, hosting providers, CDN usage, third-party integrations, and infrastructure investments. Analyze website performance metrics, security implementations, and operational maturity to inform strategic decisions.

Why deploy Web-Check on Hostinger VPS

Deploying Web-Check on Hostinger VPS provides your team with a private, always-available OSINT analysis platform without dependencies on public hosted instances or usage limits. Self-hosting eliminates concerns about sharing target domains with third-party services, ensuring operational security during sensitive investigations and competitive intelligence gathering. With dedicated resources on Hostinger VPS, you can perform unlimited scans without rate limiting, integrate Web-Check into automated security workflows and CI/CD pipelines, and maintain complete control over scan history and data retention. The containerized deployment requires minimal configuration and runs efficiently on modest VPS resources while providing consistent performance for your security operations. For security teams and consulting firms, self-hosting allows you to customize the tool with additional API keys for enhanced capabilities using premium services like Shodan, WhoAPI, and Google Cloud APIs—extending analysis depth without sharing client domains with public instances. Configure custom domains with SSL to provide your team with a professional, branded reconnaissance platform. For organizations with compliance requirements or handling sensitive investigations, hosting Web-Check on your own infrastructure ensures complete data sovereignty, prevents information leakage to external services, and maintains audit trails of all analysis activities within your security perimeter.
