In May 2025, one of the best-known names in message archiving was breached. The service ran modified versions of WhatsApp and Signal, and kept a readable copy of every client's messages on its own servers – senior US government officials' and major financial firms' alike, all in one place. The intruder reportedly needed less than half an hour. Message content was stolen, the flaw entered the US government's catalogue of actively exploited vulnerabilities, and the service was suspended.
We take no pleasure in the story – the people involved were working on the same problem we are. We retell it because the lesson is not about one company's carelessness; it is about shape. A vendor that holds everyone's archive has assembled a single, well-signposted prize. That breach wasn't bad luck. It was geometry.
So we built the opposite shape. Your messages travel through WhatsApp's official business service – no modified apps, nothing bolted on – into your own Microsoft 365, and they exist only there. We keep no copy. Our own systems see what an invoice sees: seats, tier, service health – never a word of a conversation. An attacker who wanted a hundred organisations' archives would have to breach a hundred organisations, one set of defences at a time. There is no pot of messages at our end, so there is no pot to steal.
