Web Security Service IdP authentication exemption or full bypass


Article ID: 222822


Updated On:


Web Security Service - WSS


When using the Web Security Service, you must bypass the IdP provider login URLs for authentication to succeed. 

A full bypass is recommended to maximize the performance and stability of the authentication process.

Use Cases

  • CORS-related issues
  • To prevent authentication looping with cloud-based IdP servers
  • The source device is not compatible with redirection-based authentication
  • A web application API call is not compatible with redirection-based authentication.
  • The cloud-based IdP server ACL restricting access from some or all the Web Security Service IP addresses.


Exempt From Authentication

  1. Navigate to Identity > Authentication Policy.
  2. Expand the Global Exemptions area.
  3. Click Add Auth Exemption. The portal displays the Auth: New Exemption Rule.
  4. Click Add Sources
    WSS Agents
    and Mobile Devices are static objects; selecting them to mean the exemption applies to all connections from each of those access methods.

  5. (Optional) If you need to quickly exempt a source, you can create a new entry from this wizard. For example, you need to immediately exempt a new IP address. 

    • Click IPs/Subnets.
    • Select New > IP/Subnet.
    • Enter a new address (or import a list from a text file).
    • Click Save.
    • Click Add Destinations. Select the destination elements that are exempt from authentication and click Save.
    • Click Add Rule. This creates a new Auth Exemption policy rule.
    • You can add the rule. When satisfied, click Activate.
