Network Vantage Insight (Security Diagnostics)

Description

An offline diagnostics utility to visualize browser HTTP lifecycle latency and audit client compliance based on CIS Benchmarks. [Enterprise Browser Latency Diagnostics & CIS Benchmark Compliance Tool] Network Vantage Insight (Security Diagnostics) is an offline enterprise utility designed to audit browser configuration health and break down HTTP navigation request latency components. Built strictly using standard Web Performance APIs, it translates internal browser telemetry into an intuitive visual timeline for internal support and client compliance verification. ■ Key Capabilities: 1. HTTP Request Lifecycle Mapping: Plots the native browser connection sequence (DNS, TCP, TLS, and TTFB) into a visual timeline based on standard PerformanceNavigationTiming data. 2. CIS Benchmark Auditing (CIS 1.1 & 1.2): Programmatically verifies local Chrome deployment compliance and monitors running extensions to flag potential configuration drift or untrusted development-mode agents. 3. Policy Alignment Checks: Inspects connection response flags locally to infer the presence of institutional Secure Gateways (SGW) and profile verification parameters. 4. Payload Compression Audit: Evaluates transfer vs. decoded resource sizes to document web page weight and network overhead. 5. Zero-Outbound Telemetry Policy: Completely isolates analysis inside the extension's local sandboxed container. No data is shared with external tracking APIs or public servers, eliminating inadvertent domain metadata leakage. ■ Data Governance Notice: This utility operates strictly locally and transiently. It does not possess any remote logging capabilities, nor does it capture, store, or transmit network application payload packets, PII, or browser history.
