RDAP + DNS + SSL + HTTP + Email + Propagation + Port + rDNS + ASN in one go.
OpenSecurity Tools
10 security and reconnaissance tools to analyze infrastructure, identify vulnerabilities, and verify configurations. Results include status, root cause, and next actions.
Tool List
My IP
IPv4/IPv6, ASN/ISP, request info.
OpenRDAP
Registration status, nameservers, expiry.
OpenDNS
A/MX/TXT/NS/SOA diagnostics.
OpenSSL
Expiry, SAN, chain verification.
OpenHTTP
Redirects, security headers.
OpenComprehensive email deliverability diagnostics. Check MX, SPF, DMARC, and DKIM settings for any domain.
OpenSubnet
Calculate network/broadcast address, host range, and subnet mask from IP and CIDR notation.
OpenPropagation
Check DNS record propagation status across 8+ global resolvers in real time.
OpenPort
Check if common ports are open on any host. TCP connection test to diagnose firewall status.
OpenUse Cases
Infrastructure reconnaissance
Map the target with RDAP → DNS → Propagation to understand the full infrastructure topology.
Email security audit
Verify SPF/DMARC/DKIM configuration and check MX records for proper authentication.
Exposure assessment
Scan open ports, check SSL/TLS strength, and inspect HTTP security headers for vulnerabilities.
