Two anonymous security researchers working at Dutch government found the data is send plaintext [1]. One independent security researcher was able to verify their claim.

This should be a concern if the company is owned by Dutch people, but more so if it is owned by a company with questionable jurisdiction. Which unfortunately the USA and Israel are these days.

Did they ever claim otherwise? They say "Zivver scans the content of every email" prominently on the front page. The flow seems to be TLS to Zivver first, scanning, then encryption.

If all it takes to convince us that a communication product was created as a front for spying operations is not having a strict e2e design like Signal's, then do you think virtually all of them are fronts for spying operations?

Listen, I am Dutch. I am loyal to the Dutch government, Dutch society, and therein lie my interests. This is also my potential bias.

I worked at a government organization which used Zivver. This was around 2018. It was assumed to be E2E encrypted. I wrote about the issue in my security audit, but it had low priority for a myriad of reasons (they had worse issues at the time). Zivver is more akin to the Lavabit situation.

Proton's OpenPGP.js is slightly more secure than this implementation (it encrypts client-side), but because Proton can decide (and be forced) to serve a different OpenPGP.js, it suffers from a similar issue.

I never wrote it was created as a front. I don't believe anyone asserted that. The company was founded by a couple of Dutch people in 2015, it was a Dutch company. So they fell under Dutch jurisdiction. I honestly haven't looked them up.

Fast forward to June 2025 and this company got acquired by an American company where the higher echelons are ex-Israeli spies. This could be a front, I don't know. I very much question this sale should've been ACK'ed by the Dutch government. Because due to the CLOUD act, the data now falls under American jurisdiction. Around the time of the acquisition though, the Dutch government fell. responsible up to then was Dirk Beljaarts. Around that time (June 2025), Vincent Karremans took his place. Fast forward a couple of months later, we had the Nexperia crisis, where Karremans intervened. A fallout from a stopped acquisition due to national security is lower than Nexperia fallout though.

I copied the title of the article verbatim. The Dutch article has a different title, and is IMO of better quality. The title of that article calls it a strategic blunder. I very much agree with that, but not because the top of Kiteworks is Israeli and ex-Unit 8200. That is just a cherry on top, worse case scenario a red herring. No, because of the current geopolitical situation with regards to Trump and the CLOUD act. Can you blame them for trying, given the situation and stakes? The acquisition occurred at a perfect timing.

The TL;DR is not that a American or Israeli entity supposedly succeeded. It is that the Dutch government failed. And while Zivver is heavily in use in The Netherlands, it also is within EU. So we failed to serve the best interests of EU here as well.

Thanks for the added context, that sounds reasonable to have wanted the product to continue under Dutch ownership.

There seem to be vague insinuations of a conspiracy floating around, rather than an explicit conspiracy theory, so I may have mischaracterized it. But for example, you mentioned elsewhere that "Mossad's way of operating is aggressive". Could you clarify what you're insinuating, if anything?

Hmm, from EU PoV, given many other EU countries rely on it, I believe NL is a reasonable host, but other EU countries could be as well.

I'm no expert on that subject, just following Hubert's assessment that it falls in their M.O. (already linked), following Modderkolk's recent assessment on how Mossad operates [1]. Look at all the flak I get in this thread while I just went with HN rule of 1:1 using title. Problem is all these sources are in my native language. And finally, yes my suspicion is on high alert ever since the Maccabi riots in Amsterdam [2], to which Modderkolk also refers to.

And yes, I am well aware every Israeli adult is ex-military [3]. If it were up to me, we'd restart this practice here in NL.
