Spent a long time convincing myself work still needs a VPN.

There are real threats to devices not using VPNs, such as the recent VPNFilter 
malware.

But I’d argue most of these threats also apply to the same traffic on the Internet. 
Especially if your threat model includes rogue ISPs, rogue telecoms companies, or 
well resources attackers.

In the end I decided that we needed more VPNs, but plenty of big companies came to 
the opposite conclusion.

Whilst the encryption overhead is low you pay per round trip, and to ship data 
multiple times.

That said we ship our DNS traffic over a VPN, and use HTTPS for all business 
services, so we may be less typical than most.

I’ve shied away from 3rd party DNS resolvers before, but now there is a choice of 
DNS over TLS and DNS over HTTPS I’m thinking of recommending HTTPS://1.1.1.1

Some folk seem to think this was crazy, but using a simple stable config, with 
DNSSEC, and concentrating our requests with others seems like a plausible approach 
to make it harder to target our devices, and to prevent those devices making 
insecure DNS requests.

Google reached a similar conclusion for Android P, or possibly they just want to own 
the Internet.
