This is the Cloudflare resolver, right? What's the "privacy-first" part about? It's just another third party DNS host. They haven't changed the protocol to be uninspectable and AFAIK haven't made any guarantees about logging or whatnot that would enhance privacy vs. using whatever you are now. This just means you're trusting Cloudflare instead of Comcast or Google or whoever.

"We will never log your IP address (the way other companies identify you). And we’re not just saying that. We’ve retained KPMG to audit our systems annually to ensure that we're doing what we say."

Now, audits are generally not worth very much (even, perhaps even especially, from a Big Four group like KPMG), but for this type of thing (verifying that a company isn't doing something they promised they would not do) they're about the best we have.

Where is the technical audit report published? Open access url please.

Indeed, see the recent KPMG scandal:

Worth noting they have already edited the article (less than 2hours later) and taken out the "We will never log your IP" bit...

"We committed to never writing the querying IP addresses to disk and wiping all logs within 24 hours."

"While we need some logging to prevent abuse and debug issues, we couldn't imagine any situation where we'd need that information longer than 24 hours. And we wanted to put our money where our mouth was, so we committed to retaining KPMG, the well-respected auditing firm, to audit our code and practices annually and publish a public report confirming we're doing what we said we would."

Does KPMG employ technology people? I thought they did only financial audits.

They were also implicated in tax evasion schemes in Canada.

First of all, KPMG is the name of a group. All the Big Four are arranged as group companies, a single financial entity owns the name (e.g "KPMG", "EY") from some friendly place, (London in all but one case) and licenses out the right to operate a member company to professional services companies in various jurisdictions around the world. The group has the famous name, and sets some rules about training and compliance, but the employees will (almost all) work for the local member companies even though reporting for lay people will say the group name, as they do here.

Secondly, the idea in audit is not really about digging into the engineering. So although they will need people who have some idea what DNS is, they don't need experts - this isn't code review. The auditors tend to spend most of their time looking at paperwork and at policy - so e.g. we don't expect auditors to discover a Raspberry Pi configured for packet logging hidden in a patchbay, but we do expect them to find if "Delete logs every morning" is an ambition and it's not anybody's job to actually do that, nor is it anybody's job to check it got done.

Having dealt with KPMG recently (which I do at least once a year...), I would not expect to see the report.

KPMG's risk department - the lawyers' lawyers - appears to be violently allergic to their customers disclosing any report to outside parties. Based on my experience you can get a copy, but first you and the primary customer need to submit some paperwork. And among the conditions you need to agree with is that you don't redistribute the report or its contents.

Disclosure: I deal with security audits and technical aspects of compliance.

I think it's somewhere in between, the article itself states:

"to audit our code and practices annually and publish a public report confirming we're doing what we said we would."

I run an investment fund (hedge fund) and we are completing our required annual audit (not by KPMG). It is quite thorough, they manually check balances in our bank accounts directly with the bank, they verify balances directly off blockchain (it's a crypto fund) and have us prove ownership of keys by signing messages, etc. And they do do a due diligence (lots of doodoo there) that we are not doing scammy things like the equivalent of having a raspberry pi attached to the network. Now this is extremely tough of course, and they are limited in what they can accomplish there, but the thought does cross their mind. All firms are different, but from what we've seen most auditors do decent good jobs most of the time. Their reputation can only be hit so many times before their name is no longer valuable to be an auditor.

A DNS resolver does need to record the querying IP for at least a few moments because, you know, they have to respond to your query.

However, I don't know why they changed that sentence; it could be for other reasons too.

Seems like they're just trying to be clear.

It's not uncommon to retain logs like that for debugging purposes, abuse prevention purposes, etc, but then to go back later and wipe them or anonymize them.

Isn't that the entire point of such an audit? To be able to present it to outside third-parties?

For examples, Mozilla (CA/B) requires audits for root CAs. The CA must provide a link to the audit on the auditor's public web site -- forwarding a copy or hosting it on their own isn't sufficient.

Not sure if they edited anything. Your quote is from the blog post[1] but the aforementioned quote by tialaramex is from the 1.1.1.1 site itself[2].

You'd think, but it's surprisingly difficult to get the real full audit report. Mozilla's root policy _does_ require that they be shown the report, and has a bunch of extra requirements in there to ensure they're more detail, rather than some summary or overview document the auditors were persuaded to produce for this purpose. But the CA/B rules would allow just an audit letter which basically almost always says "Yes, we did an audit, and everything is fine" unless the auditors weren't comfortable writing "everything is fine". And almost always they feel that a footnote on a sub-paragraph buried in a detailed report is enough to leave "everything is fine" as the headline in the letter...

If you've ever been audited for some other reason, you'll know they find lots of things, and then you fix them, and that's "fine". But well, is it fine? Or, should we acknowledge that they found lots of things and what those things were, even if you subsequently fixed them? The CA/B says you have several months to hand over your letter after the audit period. Guess what those months are spent doing...

How do we know they are not lying (or forced to lie, they are a US company after all)?

Auditors will confirm the result of the audit but usually not disclose the content of the audit report.
