+## Running behind a TLS-inspecting proxy (corporate / custom CA bundle)
+
+If your network sits behind a TLS-inspecting appliance (Zscaler, Netskope, Palo Alto, etc.) that re-signs HTTPS traffic with a corporate CA certificate, the reporter will fail with `x509: certificate signed by unknown authority`. To fix this, make the appliance's CA bundle available to the reporter.
+
+The chart offers two ways to do this. Use whichever fits your deployment flow.
+
+### Option 1 — `customCA` convenience wrapper (recommended for the common case)
+
+1. Create a Secret containing the corporate CA certificate (PEM format, single cert or bundle):
+
+```shell {.command}
+kubectl create secret generic corporate-ca-bundle --from-file=ca.crt=/path/to/corporate-ca.crt
+```
+
+2. Enable the wrapper in `values.yaml`:
+
+```yaml
+customCA:
+  enabled: true
+  secretName: corporate-ca-bundle
+  key: ca.crt
+```
+
+The chart mounts the certificate as a single file at `/etc/ssl/certs/kosli-custom-ca.crt` using `subPath`. Go's standard library on Linux loads CA roots in two independent passes — it reads the system bundle file (e.g. `/etc/ssl/certs/ca-certificates.crt`) and **also** scans `/etc/ssl/certs/` for additional certificate files. The mounted file is picked up by the directory scan and added to the trust store alongside the system roots, so no `SSL_CERT_FILE` env var is needed.
+
+The wrapper deliberately does **not** set `SSL_CERT_FILE`. Setting it would replace the system bundle entirely with the customer's file, breaking trust for any public CAs the bundle does not include.
+
+### Option 2 — generic `extraVolumes` / `extraVolumeMounts` / `extraEnvVars`
+
+Use these when you need a non-default mount path, a ConfigMap instead of a Secret, multiple volumes, or any other shape the wrapper does not cover:
+
+```yaml
+extraVolumes:
+  - name: corporate-ca
+    secret:
+      secretName: corporate-ca-bundle
+
+extraVolumeMounts:
+  - name: corporate-ca
+    mountPath: /etc/ssl/certs/corporate
+    readOnly: true
+```
+
+Note: if you mount the CA outside `/etc/ssl/certs/` and set `SSL_CERT_FILE` via `extraEnvVars`, your bundle must include the public CAs you also need to trust — Go uses only that file when `SSL_CERT_FILE` is set.
+
+### Pod Security Standards
+
+Both options use `secret`-backed volumes, which are permitted under the Pod Security Standards `restricted` profile. `hostPath` mounts are not permitted under that profile and should not be used here.
+
+### Cluster-wide alternative
+
+If you already run [cert-manager's trust-manager](https://cert-manager.io/docs/trust/trust-manager/) to distribute a corporate CA bundle into a well-known ConfigMap in every namespace, point `extraVolumes` / `extraVolumeMounts` at that ConfigMap instead of creating a per-namespace Secret.
