Purpose
This guide explains how to generate an API credential in the Blue Coat / Symantec Cloud SWG portal and how to enter it in Logsign USO to ingest web proxy access logs for security analytics and forensic purposes.
Blue Coat Systems was acquired by Symantec in 2016, and the product line has since moved under Broadcom (which acquired Symantec's enterprise security business in 2019). What was originally sold as Blue Coat's cloud proxy service, internally named ThreatPulse, is now documented and marketed as Symantec Web Security Service (WSS) or Cloud Secure Web Gateway (Cloud SWG). Despite the rebranding, the portal domain and the log export API this integration uses have not changed: both the login portal and the Sync API endpoint are still hosted at portal.threatpulse.com. This same hosted reporting backend can also receive uploaded access logs from an on-premises ProxySG or Edge SWG appliance, so the logs this poller retrieves may originate from the cloud proxy service itself or from an appliance configured to forward its logs into Cloud SWG's hosted reporting. Either way, Logsign retrieves them through the one Sync API described below. This is a separate, cloud-based collection path from Logsign's existing syslog/CEF connector for on-premises Blue Coat ProxySG appliances; if you forward logs directly from an appliance via syslog today, you do not need this integration as well, unless you specifically want the hosted reporting copy pulled through the API too.
Prerequisites
You need access to the Blue Coat / Symantec Cloud SWG portal at portal.threatpulse.com with permission to reach Account Configuration > API Credentials. This is normally an administrator-level account for your organization's Cloud SWG tenant.
Use least privilege. When you create the credential, set its Access to Reporting Access Logs rather than a broader administrative scope. Per Broadcom's own SIEM integration guidance for Cloud SWG, this is the access level intended specifically for log-export credentials like the one this integration uses. The exact wording and layout of this option have not been verified against a live console for this document, so confirm the option list in your own portal matches before assuming an identical checkbox label.
Step 1: Generate an API Credential in the Cloud SWG Portal
- Sign in to
https://portal.threatpulse.comwith an account that has administrative access to your organization's tenant. - Go to Account Configuration > API Credentials.
- Click Add API Credentials (labeling may vary slightly by portal version).
- For Access, select Reporting Access Logs (see Prerequisites above).
- Save. The portal auto-generates a Username and Password pair for the credential; these are only shown once. Copy both immediately and store them somewhere safe. If you lose them, you must generate a new credential.
Step 2: Configure the Integration in Logsign USO
In Logsign USO, add a new Blue Coat API data source. You will be asked for:
| Field | Value |
|---|---|
| Username | The Username generated in Step 1 |
| Password | The Password generated in Step 1 (entered as a masked field) |
| Log Collection Period | How far back to look on the very first poll: 1 Hour, 3 Hours, 6 Hours, or 12 Hours |
There is no Host or Base URL field for this integration. Logsign always calls a single fixed endpoint, https://portal.threatpulse.com/reportpod/logs/sync, regardless of which region your tenant is provisioned in. Broadcom's own API documentation does not describe a separate regional endpoint for this API, so there is nothing to look up or copy from your console for this field, and no https:///trailing-slash format trap to worry about here since you never type a URL into this form.
Once saved, Logsign calls the Sync API on each polling cycle and downloads a ZIP archive containing gzip-compressed access log files in Extended Log File Format (ELFF, also known as the W3C extended log format). Logsign extracts, parses, and posts each log line as a Logsign event. The Log Collection Period only controls how far back the very first poll looks; every following poll resumes automatically from the end of the previous successful run, so changing this value later has no effect on an already-running source.
Troubleshooting
| Error | Likely cause | What to check |
|---|---|---|
| 401 Unauthorized | The Username/Password pair is wrong, was deleted, or was regenerated in the Cloud SWG portal. | Compare the Username and Password in the Logsign source configuration against the current values on the portal's API Credentials screen. Since the Password is only shown once at creation time, generate a fresh credential rather than guessing if you are unsure of the current value. |
| 403 Forbidden | The credential authenticates, but its Access setting does not include Reporting Access Logs, or was changed away from it after creation. | In the portal, open the credential under Account Configuration > API Credentials and confirm its Access still grants log/reporting access. |
| 409 Conflict | Per Broadcom's Sync API documentation, this is returned when too many requests using token=none are made in a short period, and can block further requests from the same credential for up to about 90 minutes. This poller queries with token=none on every single poll cycle instead of resuming with the token the API returns (see Notes below), so an unusually short polling interval is the most plausible trigger; this has not been reproduced against a live tenant for this document. | Avoid setting an aggressively short polling interval for this source, and avoid repeatedly re-saving or test-connecting the source in quick succession. If you hit this, wait roughly 90 minutes before the next poll can succeed. |
| 423 Locked | Cloud SWG allows only one active Sync API request per credential at a time; this is returned when a previous request using the same credential has not finished yet. | Confirm the same Username/Password pair is not also configured on another Logsign data source, or on another SIEM/tool, polling in parallel. |
| 429 Too Many Requests | General Cloud SWG API rate limiting. The exact requests-per-minute threshold for this endpoint is not published by Broadcom. | If this appears repeatedly, contact Logsign support; this poller does not currently implement automatic backoff/retry for 429, a failed poll simply retries on the next scheduled cycle. |
Notes and Limits
- There is no Host/Base URL field because this integration always targets a single fixed endpoint,
portal.threatpulse.com. No regional variant of this address is documented by Broadcom at the time of writing (July 2026). - This poller requests data with a plain
startDate/endDatewindow and always sendstoken=none. Broadcom's current Cloud SWG documentation marks this request style as deprecated in favor of a token-based continuation flow using theX-sync-tokenvalue returned in each response, which this poller does not implement. At the time of writing the deprecated style is still accepted, but this is not guaranteed to remain the case indefinitely. - Broadcom's documentation states that
startDatemust reference data from within the last 7 days. If this source is left un-polled for longer than that (for example, paused for an extended period), the gap beyond 7 days is not retrievable through this API regardless of Logsign's own saved position; those logs are permanently missed. - This source appears in Logsign as Vendor "Blue Coat" and Product "ProxySG" for continuity with Logsign's existing syslog/CEF collector for on-premises ProxySG/Edge SWG appliances, which uses the same EventSource identity. This API poller is a separate, cloud-based collection path and does not require or use a syslog listener.
- Only proxy access logs in ELFF/W3C extended log format are retrieved through this API. Per Broadcom's documentation, the Sync API does not export Cloud Firewall, Sandboxing, or DNS module logs; those would require a separate integration if you need them.
- This poller does not currently validate the TLS certificate presented by
portal.threatpulse.com. Certificate verification is disabled in the current implementation; this is a property of the integration itself, not something you configure. - The set of fields captured per log line is read dynamically from each file's own
#Fields:header rather than a fixed schema, so you do not need to configure a field list. Not every field is currently mapped into Logsign's normalized event schema; unmapped fields are retained in the raw event but may not be available for normalized correlation rules.
