At the 65th IT press tour in AthensI have met Imran Nino Eskić And Bostjan Kirm by HyperBunker and heard many well-known claims about defending against ransomware. Better detection. Smarter prevention. Faster response. But one conversation cut through the noise by focusing on what actually happens after all that goes wrong.
The team behind HyperBunker wasn’t there to sell another backup product. They were there to talk about recovery certainty and why so many organizations are quietly discovering they don’t have it.
Their premise is uncomfortable, but hard to argue with. In modern environments, backups are often the first systems that attackers go after. Login details are stolen. Backup repositories are encrypted. Cloud replicas are compromised long before the alarm is raised. By the time recovery is needed, the data that organizations thought they could salvage is already gone.
A product shaped by failure, not theory
HyperBunker did not emerge from a cybersecurity lab or threat modeling exercise. It was built by people who spent decades working in data recovery and dealing with the aftermath of incidents where all other safeguards had failed.
The founding team has over 25 years of experience and has handled over 50,000 data recovery real-world cases. Their perspective is shaped by the nights and weekends they spend answering calls from executives who had already been breached and discovered that recovery was impossible. That experience led them to a clear conclusion. As long as backups remain connected, they remain accessible. And everything that is accessible is eventually affected.
Many backup strategies are based on concepts such as immutability, air gaps, or isolated cloud accounts. HyperBunker’s argument is not that these ideas are wrong in principle, but that they fail in practice.
Industry data reinforces this point. A small percentage of attacks ever result in warnings. A significant number of environments offer paths to full administrative control. Ransomware prevention rates remain inconsistent depending on the group of attackers. And AI is accelerating the rate of intrusion faster than human-led response can realistically keep up.
The result is a growing gap between how backups are expected to behave and how they perform under real attack conditions. HyperBunker exists to bridge that gap.
What HyperBunker actually does
HyperBunker describes itself as an offline recovery vault and not a backup device. It is designed to store a single clean, immutable copy of the data an organization needs to survive, completely out of reach of network-based attacks.
At the heart of the system is a patented butler mechanism that functions as a physical airlock. Data can move inward along a one-way path, passing through two physical air gaps that are never open at the same time. Once data reaches the cold vault, it is completely offline.
There are no credentials involved, no cloud APIs, and no remote access paths. Even monitoring is only possible in one direction. The system can communicate the status to the outside world, but cannot be controlled remotely. Recovery requires physical presence on the device.
This is a conscious design choice. HyperBunker assumes that credentials will eventually be stolen and networks will eventually be breached. The system is built around the idea that the only secure data is data that attackers cannot see or reach.
Unlike many backup platforms, HyperBunker does not attempt to inspect or clean incoming data. Instead, it focuses on ensuring that once data is stored, it cannot be executed, encrypted itself, or changed by anything online.
Multiple immutable versions are preserved so organizations can revert to previous versions if necessary. The emphasis is not on perfect prevention, but on ensuring that at least one reliable copy survives if everything else is compromised.
This reflects the team’s recovery-first mentality. In their experience, recovery is the moment that determines whether a company comes back.
Why critical industries pay attention
HyperBunker is gaining interest in industries where downtime directly leads to regulatory failure, security risks or system disruption. Energy and utilities, healthcare, manufacturing, transportation, finance and government are all operating under conditions where recovery timelines are as important as prevention.
Cyber insurers are also noticing this. Insurance losses are often caused by a failed recovery rather than an initial breach. That’s why US-based cyber insurer Cowbell validated HyperBunker’s offline model and added it to its marketplace.
Incident responders repeat the same observation. In post-incident investigations, the only data that was reliably retained was data that attackers could not access.
Not a replacement, but a final layer
The HyperBunker team is clear that their system is not intended to replace cloud platforms, backup software, or cybersecurity tools. These systems serve important purposes and must continue to exist.
HyperBunker is designed to sit behind everything else. It’s the last layer, the one that assumes all others may fail. In that sense, it functions more like a black box recorder than a traditional backup.
As ransomware pressure increases, regulations tighten, and geopolitical risks reshape infrastructure decisions, offline recovery is disappearing from the technical margins. It becomes a matter of governance and resilience, and not just an IT problem.
HyperBunker reflects that shift. It is built around a simple promise. If all else fails, the last copy survives.
I plan to continue monitoring their progress. If you were to hear from the HyperBunker team on a future podcast episode, what questions would you like to ask them?
