About:
ike-scan is a command-line tool designed to discover and fingerprint Internet Key Exchange (IKE) hosts. It sends IKE requests to target hosts and analyzes the responses to identify the VPN concentrator or security gateway vendor. This information is invaluable for network reconnaissance and security auditing.
Key Features:
  • Aggressive mode support for user identification
  • IPsec VPN fingerprinting capabilities
  • Customizable payload and retransmission settings
  • Supports multiple transform (encryption/hashing) types
Use Cases:
  • Network reconnaissance and asset discovery
  • Security auditing of VPN configurations
  • Identifying VPN concentrator vendors and versions
Alternatives:
  • Nmap – Nmap has an IPsec discovery script, but ike-scan is specialized for deeper IKE protocol fingerprinting.
  • SwanScan – A modern alternative, but ike-scan remains the standard for granular control and fingerprinting.
