# Zscaler Client Connector vs MSD One

The clearest difference is rating: MSD One at 4.4 against Zscaler Client Connector's 2.5. Zscaler Client Connector's advantage is update cadence (monthly vs every 6 months) and review sentiment (25% vs 0%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

MSD One holds the better App Store score, 4.4 against 2.5. That said, the two scores are not equally well evidenced: Zscaler Client Connector has 140 ratings behind it against 7, so its average is the more settled of the two. 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.

Zscaler Client Connector ships an update monthly, MSD One every 6 months. The most recent releases landed on October 21, 2026 and October 16, 2026 respectively.
