The Zscaler App for iOS includes both Zscaler Internet Access and Zscaler Private Access modules. Mobility has raised business productivity, but it’s brought its share of issues, as well. One of the biggest challenges is the need to provide complete, consistent security across devices that you may not own. The majority of web traffic from mobile devices comes from apps, not from standard browsers, so threats may not even be visible to traditional security appliances. Note: Zscaler App is used with an active enterprise subscription to Zscaler's Mobile Security service. Please follow instructions from your IT organization to use this app. Zscaler App automatically creates a lightweight HTTP tunnel that connects the user’s endpoint to Zscaler’s cloud security platform with no need for PAC files or authentication cookies. The Zscaler Cloud Service delivers one-step enrollment, with multifactor authentication support via SAML. If you are an end-user and have issues or concerns, please reach out to your organizations support. Client Connector does not collect any personal information about you, or your device, however traffic your device sends to websites and SaaS applications is visible by your company administrators.

MSD One holds the better App Store score, 4.4 against 2.5.

Written reviews complicate that: 25% of Zscaler Client Connector's written reviews are positive against 0% of MSD One's, so the app with the better star average is not the one people write more warmly about.
