Network Exposure Tester

Goes beyond a SYN scan — performs the real protocol handshake to confirm whether a service is genuinely reachable, or whether an application-layer firewall is silently blocking it.

Authorized use only. Only scan hosts you own or have explicit written permission to test. Unauthorized port/protocol scanning may be illegal (e.g. the U.S. Computer Fraud and Abuse Act and equivalent laws elsewhere). You are solely responsible for how you use this tool.
Single host8.8.8.8 or host.example.com  ·  CIDR1.2.3.0/24 (max /24)  ·  List — up to 50 hosts, one per line. Public targets only.
⚠ SNMP credentials are stored in your browser in plain text and sent unencrypted in the request. Do not use production company credentials here. v3 uses authPriv (SHA / AES) with the password for both auth and privacy.
