Onavo VPN maybe? 2018

Onavo Protect, the VPN client from the data-security app maker acquired by Facebook back in 2013, has now popped up in the Facebook iOS app itself, under the banner “Protect” in the navigation menu. Clicking through on “Protect” will redirect Facebook users to the “Onavo Protect – VPN Security” app’s listing on the App Store.
