In this episode of Tech Talks Daily, I get to work with Imran Nino Eškić and Boštjan Kirm from HyperBUNKER to explain a problem that many organizations only discover in their darkest hours. Backups should be the safety net, but in real ransomware incidents they are often the first thing attackers dismantle. Talking to two people who cut their teeth in data recovery labs on 50,000 real cases gave me a very different perspective on what resilience actually looks like.
They explain why so many so-called “air-gapped” or “immutable” backups still rely on identities, APIs, and network paths that can be exploited. We discuss how modern attackers patiently map environments for weeks before neutralizing recovery systems, and why that shift makes true physical isolation more relevant than ever. What struck me most was how calmly they described failure scenarios that would keep most leaders awake at night.
The core of the conversation revolves around HyperBUNKER’s offline vault and its spaceship-style dual airlock design. Data enters through a one-way hardware channel, the network door closes, and only then is the information moved to a completely cold vault with no address, no login credentials, and no remote access. I also think about seeing the black box in person at the IT Press Tour in Athens and why it feels less like a gadget and more like a last resort.
We end with a discussion about how companies should decide what really belongs in the protected 10 percent of data, and why this is as much a leadership decision as an IT decision. If everything were to disappear tomorrow, what would your business need to breathe again and could it actually survive?
