Guided log analysis
Surfaces known Zscaler error codes, tunnel setup and connection failures, warnings, and the matching raw records behind each finding.
Open sourceRuns locally
Move from ZCC logs to the next action faster.
ZCC Log Explorer turns Zscaler Client Connector support bundles and individual logs into a guided troubleshooting view for new customers and experienced engineers.
Clone locally
git clone https://github.com/SecureDynamicsInc/ZCC_Analysis.gitThe project is now public. This is the official SecureDynamics public open-source repository. No access request is required. Use Issues for problems and pull requests for improvements; protected main remains under SecureDynamics maintainer control.
One local troubleshooting workspace
The evidence you need, with less tool switching.
Upload a complete support ZIP when the cause is unknown, or start with an individual tunnel log for the fastest first pass in most connection investigations.
Colorized evidence
Read tunnel logs and PAC files in a clear, colorized viewer on the same page, without bouncing between the analyzer and a separate text editor.
Network context
Connect IP addresses to available hostnames, DNS activity, endpoints, and providers so the destination behind a failure is easier to understand.
Packet capture insight
Highlights DNS failures, TCP resets, and suspicious streams, then provides useful Wireshark display filters when deeper packet validation is needed.
Start simple. Go deeper when needed.
A useful answer for every experience level.
ZCC Log Explorer leads with the conclusion, explains why it matters, and keeps the supporting evidence one step away.
Novice mode
Tell me what failed and what to try.
- Plain-language findings
- Prioritized known errors
- Clear next steps
- Easy warning and error filters
Pro mode
Show me the underlying technical signals.
- Matching log records
- Destination and hostname detail
- Packet-capture signals and filters

Local by design
Your diagnostics stay on your workstation.
The interface runs at http://127.0.0.1 and analyzes files locally. It does not require uploading a customer support bundle to a hosted analysis service.
Important: use http://, not https://, when opening the local application.
Optional enrichment
Add MaxMind GeoLite databases.
Upload your own GeoLite database files to enrich IP addresses with available ASN, provider, and geographic context. The databases are not bundled with the project.
These results are useful investigative hints, not proof of ownership or physical location.
