Web-check is an open-source tool designed for gathering detailed intelligence about websites. It provides insights into various aspects, including IP information, SSL certificates, DNS records, and server architecture. Users can analyze security configurations and identify potential vulnerabilities in a straightforward manner. The dashboard currently displays a range of data, such as IP info, SSL chain details, DNS records, cookies, headers, and more, with plans for further enhancements. The tool helps users understand how a website functions and how to optimize its performance. For instance, examining SSL certificates can reveal the authenticity of a site and its security posture, while analyzing DNS records can disclose the IP addresses and email providers linked to a domain. Understanding cookies can shed light on user tracking practices, and reviewing HTTP headers provides insight into server configurations and security measures. Web-check also assesses site performance using Lighthouse, providing metrics on accessibility, best practices, and SEO health. It identifies the physical location of servers, which can influence content delivery and compliance with data residency regulations. Additionally, it can identify associated domains and subdomains, helping users gain a broader understanding of a site's online presence. This information is valuable for both website owners looking to enhance security and performance and researchers conducting OSINT investigations.
