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 the known software conflicts for Cisco Security Connector (CSC).

    What Are the Known Software Conflicts for Cisco Security Connector?

    The Cisco Security Connector (CSC) is known to not function correctly in the presence of some software and certain scenarios.

    Under these conditions, the CSC can report Protected, but web traffic does not apply policy:

    • VPNs: Per Apple's design, the CSC cannot receive DNS packets for traffic bound for a VPN. This is expected behavior.
    • Mobile Hotspot: Clients connected to an iPhone running a hotspot are not covered by the CSC. The phone operating the hotspot can continue to have coverage.
    • Wandera "Gateway": Apple recognizes the Wandera proxy as a VPN-like gateway. Therefore, any traffic sent via Wandera cannot receive CSC coverage. CSC can see many DNS requests to *.proxy.wandera.com as a sign that Wandera is active.
