During the fourth calendar quarter of 2020 and the first calendar quarter of 2021, NCC Group conducted an in-depth review of the VPN by Google One virtual private network system. The focus of the engagement was to assess the product’s technical security properties and review its associated privacy claims.
The public report for this assessment may be downloaded below. A followup assessment was performed in late 2022, and the public report for that assessment can be found here.
