Prevents outdated protocols such as SMBv1 or unencrypted LDAP from compromising your corporate network.
Can be integrated into modern, zero-trust architectures – even for legacy devices.
Each OT-Shield acts as an individual security zone – without the need to rebuild existing infrastructure.
Insecure protocols are encapsulated, checked, and forwarded securely.
Existing systems can continue to run – without changes to software or operating system.
All connections become traceable – for audits, compliance, and forensics.
Securely connect old PLC systems (e.g., with SMBv1 shares) to modern networks.
Continue to use these systems, but with a secure network boundary.
Securely isolate devices that cannot be updated.
Secure and audit outdated authentication systems.
Secure access to internal systems without complete migration.
Securely connect legacy components in energy, water, transportation, etc.
IT security managers who cannot simply shut down outdated systems.
Network architects who want to implement zero trust – even with legacy systems.
CISOs in regulated industries (healthcare, energy, finance).
Forensic and audit teams who need visibility into legacy communications.
OT/IoT managers who need to secure production systems.
MSPs/system houses who are looking for secure solutions for customer environments.
The OT-Shield is placed between the legacy system and the network. It encapsulates insecure protocols, replaces or hardens them, and establishes secure communication – including authentication, encryption, and logging.
No. The OT-Shield works without any changes to the target system. It speaks the old protocols and translates them internally.
Yes, this is technically possible – however, for security reasons, we recommend one OT-Shield per system in order to enable a consistent seperation of zones.
