Cyber resilient storage

HyperBUNKER – the last line of defense for your Most critical data

When security systems fail, recovery of critical data must be guaranteed

Modern organizations invest heavily in advanced cybersecurity solutions, backup systems, and disaster recovery platforms. Nevertheless, we are increasingly seeing cases where cybercriminals successfully compromise backup copies, administrator accounts, and recovery infrastructure as well. Organizations that cannot afford to lose their most critical data need an additional layer of resilience.

As a HyperBUNKER partner, Optisis delivers a solution designed to protect your most valuable data in scenarios where everything else has failed. HyperBUNKER is a physically isolated, immutable offline data vault that ensures recoverability even after the most severe cyber incidents.

What is HyperBUNKER?

HyperBUNKER is a hardware-based solution for secure, physically isolated offline data storage, designed to ensure data recovery even when conventional security mechanisms and backup systems have been compromised.

It serves as the final line of defense against ransomware, insider threats, and catastrophic cyberattacks.

Its greatest strength is complete physical network isolation (air gap), preventing attackers from accessing stored data.

HyperBUNKER uses a patented one-way data transfer mechanism ("butlering") that allows data to be written into the vault but prevents it from being modified or deleted.

Why HyperBUNKER?

Modern organizations face increasingly sophisticated cyber threats, including:

Ransomware attacks capable of compromising primary systems and backup environments,
Insider threats and misuse of privileged accounts,
Advanced cyber sabotage and infrastructure compromise,
Requirements for compliance with regulations and standards such as the GDPR, HIPAA, PCI DSS, DORA, IEC 62443 and the NIS2 Directive.

Traditional backup and disaster recovery solutions remain an essential part of every cybersecurity strategy. However, because they are often connected to the network, they can also become targets of cyberattacks. HyperBUNKER provides a physically isolated, immutable offline vault, ensuring that at least one clean copy of your most critical data remains protected from network-based threats.

Key benefits

Physical Isolation – HyperBUNKER is not network-addressable and cannot be reached through cyberattacks.
One-Way Data Transfer – The patented "butlering" technology enables data to be written into the vault while preventing reverse access through the same path.
Dual Physical Air Gap - Data passes through a secure dual air-gap mechanism, ensuring the vault is never simultaneously exposed.
Immutable Storage - Once stored, data cannot be modified or deleted through online systems.
Versioning - Multiple immutable versions enable recovery to previous points in time.
Credential-Free Recovery - Recovery does not require domain accounts, passwords, or network access.
Compliance - Helps organizations meet the requirements of regulations and standards such as GDPR, HIPAA, PCI DSS, DORA, the NIS2 Directive and IEC 62443 for OT/ICS cybersecurity and operational continuity in industrial control environments.

How does HyperBUNKER work?

Data is written into the vault through a one-way data path, preventing data extraction or manipulation.
Data is stored in a physically offline environment, with no network connectivity or remote access.
Write operations and media handling are managed by dedicated hardware logic with no operating system and no network interface. Because there is nothing network-addressable to reach, the control layer cannot be reached or altered remotely.
Data recovery requires physical access to the device, ensuring complete separation between the compromised online environment and the protected offline vault.

This architecture allows data to enter the vault while making it impossible to access or manipulate it remotely.

Who is it for?

HyperBUNKER is particularly suited for organizations operating in critical sectors where data loss represents significant operational, regulatory, or security risks, including:

Energy and utilities
Healthcare
Banking and financial services
Manufacturing and transportation
Telecommunications
Government and critical infrastructure

HyperBUNKER as part of your cyber resilience strategy

HyperBUNKER is not intended to replace your existing backup or disaster recovery solution. Instead, it adds an independent layer of cyber resilience, complementing existing backup infrastructure and providing the last reliable recovery option for your most critical data.

This approach is especially valuable for organizations seeking to:

Reduce the risk of total data loss caused by ransomware,
Maintain an independent and immutable copy of critical data,
Ensure business continuity even after a complete compromise of the IT environment,
Strengthen compliance with cybersecurity regulations and industry standards.

Frequently asked questions

No. HyperBUNKER complements existing backup and disaster recovery solutions by adding an independent, physically isolated layer of protection.

Yes. Because the vault is physically isolated and inaccessible through the network, ransomware cannot reach or encrypt the stored data.

Data immutability is ensured through the patented one-way data transfer mechanism, dual physical air-gap architecture, and offline storage without network connectivity.

Recovery requires physical access to the system, ensuring complete separation between the compromised production environment and the protected offline vault.

Yes. HyperBUNKER supports the protection, immutability, and resilience requirements that are fundamental to organizations subject to the NIS2 Directive.

Protect the Data You Cannot Afford to Lose

Cybersecurity is no longer only about preventing attacks. The real question is:

Can you reliably recover your most critical data after a successful cyberattack?

HyperBUNKER provides the final, physically isolated layer of protection for organizations that require absolute certainty in critical data recovery.
