Zscaler runs as a cloud security proxy. It inspects traffic. It blocks threats. It enforces policy. What it also does is move the choke point. All requests flow through its nodes. If you want to audit or investigate, you must pull logs directly from Zscaler’s systems.
Access logs from the Zscaler proxy record every HTTP request, every source IP, every user session, every URL, and every verdict. They are the single source for correlation between user action and network events. Without them, your SIEM shows blind spots.
You can retrieve Zscaler logs using its API. Request them in batches, parse them for the fields you need, and push them downstream into your preferred storage. Common fields include timestamp, user name, source IP, destination domain, action taken, and threat category. Engineers often push this data into Splunk, Elastic, or S3 for processing. Fast pipelines matter; latency turns investigations cold.
