Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

    Introduction

    This document describes how to address access denied errors for certain websites when using Secure Web Gateway (SWG).

    Issue

    Users of Secure Web Gateway can experience an issue where they cannot reach specific websites and instead receive an access denied page.

    The issue appears as users being unable to access the website, receiving an access denied message.

    For example, the page displays a block notification attributed to Akamai:

    2370701976667623707019766676
    2370957427227623709574272276

    Cause

    The website owner has implemented this block through Akamai CDN, which uses mechanisms to restrict access from Secure Web Gateway IP ranges. Typically, such blocks occur automatically based on Akamai IP reputation mechanisms or other security policies configured by the site owner.

    Action

    Contact the site administrators and request that they allow access, particularly if a business relationship exists with the site. Because the issue is a 3rd party access denial, Umbrella Support has limited options to assist.
