What's included

Five diagnostic modules

Everything a security engineer needs to diagnose network and proxy issues — without opening a browser or installing anything.

⬡
TCP Ping

Real-time TCP connectivity test with per-probe status, latency statistics and automatic diagnosis when connections fail.

OPEN REFUSED TIMEOUT avg / min / max
⬡
MTR Trace

Hop-by-hop path analysis using native tracert — silent background execution, real-time output, automatic anomaly detection.

Packet Loss High Latency Spikes
⬡
DNS Lookup

Query any DNS server for any record type. Presets for Cloudflare, Google and Quad9. Diagnoses split-DNS scenarios.

A / AAAA CNAME / MX NS / TXT / PTR
⬡
Page Load Test

Measures DNS, TCP, TLS handshake and TTFB with waterfall visualization. Detects SSL inspection overhead and proxy latency.

Egress IP TLS Timing TTFB Waterfall
⬡
Process Explorer

Live TCP/UDP connection monitor per process. IPv4 and IPv6, auto-refresh, DNS resolution, state-colored table. Similar to TCPView.

ESTABLISHED LISTEN IPv4 / IPv6 Auto-refresh
Why SSE Toolkit
