RDP Checker

RDP Checker provides a focused, protocol-aware assessment of remote desktop reachability for IT operations and security teams. It accepts target identifiers, validates inputs, and performs a sequence of checks that surface immediate visibility into whether a remote endpoint is reachable on the RDP port and whether basic network controls permit access. By separating inputs from analysis, it enables repeatable testing across environments and change windows.

Conceptually, the tool models a typical connectivity workflow: validate the IP and port, establish a TCP connection, optionally capture a banner, and infer basic service characteristics. The system emphasizes deterministic results and structured outputs, making it suitable for integration with monitoring, ticketing, or incident response workflows. It does not perform credential compromise; it simply reports reachability and safe indicators of service exposure.

Core value lies in early risk signaling. A open port with no banner still signals potential exposure, while a known banner or TLS indicator can guide mitigations such as firewall rules or stricter access controls. The results include a risk score, actionable recommendations, and export options to support post-test reviews and compliance documentation.

Use cases include pre-deployment checks for RDP allowlists, periodic security posture reviews, and network audits. The tool is designed for internal networks and authorized assessments, offering fast, repeatable results that help teams prioritize remediation and reduce unplanned downtime.
