Offline Update

Offline Update

The link22 Offline Update enables greater security when updating software in physically separated environments. The product automates and secures the download flow of software updates. link22 Offline Update automatically retrieves files, through a scheduler, onto a security airlock. In the security airlock, the file is inspected with link22 Guard and customizable filters. One of the filters allows the file to be broken down and reassembled according to the principles of “Content Disarm and Reconstruction (CDR)”. The file is then distributed to the correct location in the target system. link22 Offline Update is designed for one-way data flows over data diodes.



Some file exports have to be approved by a third person, preferably by signature verification. Document countersign protects both humans and documents. That’s what link22 Countersign is for.

Deep Inspection (CDR)

Deep inspection (CDR)

Content Disarm and Reconstruction (CDR) from Glasswall enhances protection against previously unknown threats and so-called zero-day attacks. With CDR, each file can be deconstructed, validated, cleansed, and reconstructed based on specifications of known and well-defined file types that are safe and permitted in your business. The capability of CDR allows you to shift from passive to active review and protect against zero-days where other solutions fall short.

Data Diodes ensure unidirectional data traffic between domains. link22 Data Diode Zero is a highly cost-effective product that provides network separation using an internal unidirectional optical fiber.

Cross Domain Solutions

Cross domain solutions

Certain files should be transferable, some should not. Certain files can be transferred if they do not contain sensitive information. Some files are only transferred if they are signed. Some files can be exported but not imported, or vice versa. We are experts in cross domain solutions and can offer turnkey products in this domain.
