Should I use DNS over TLS? How about DNS over HTTPS?

Security is at the forefront of what we do at DNSFilter, and is always on everyone's mind these days. So I'm sure you may have heard of two different methods of secure DNS - DNS over HTTPS (DoH), and DNS over TLS (DoT)

DoH is at the forefront right now because it’s what Google uses, but it’s not necessarily better than DoT. It’s just different, and in some ways, it’s actually inferior to DoT.

DoT is actually a more efficient method because of the layer within the TCP/IP model it is enabled in.

Remember, DoH is two layers removed from the internet layer, while DoT is only one layer removed.

See our blog for a high-level breakdown:

DNSFilter uses DoH as part of our Chromebook Roaming Client, but it is not a directly useable service outside of that at this time.

DoT, however, is, and if information for instructions on how to enable it is desired, this information can be found in the Enabling DNS-over-TLS documentation.

More information on DNS over TLS over HTTPS can be found in the DNS over TLS over HTTPS documentation.
