To better understand web security as it is experienced around the world, we scan the
top 500 most visited sites of internet users from nine countries of interest. We document
HTTPS usage, the public key encryption and signing algorithms, and certicate informa-
tion, including issuing date and length of validity. Insights from this project will help
benchmark web security prior to upcoming browser interventions[3], and identify regions
that may benet from capacity building to implement TLS in the future.
