Spyse is a Cyber Search Engine that collects data across the whole internet and delivers it in a structured view. Spyse collects more emails than hunter.io or snov.io and connects this information to domain names. The data that is collecting is huge: subdomains, DNS records, SSL certificate details, technology stacks, subnets, IPs, CVE details, and more. The feature is more useful for Network Administrators, Bug Hunters, and security Engineers to prevent unwanted port open issues.
