Do you have a question? We will answer it!

In the FAQs, we collect answers to general aspects and terminology in the context of product support. Specific product information is listed in separate areas such as the knowledge base or release notes.


Release notes and release information

The release notes provide an overview of the new features and changes in a version and an installation guide for installing the upgrade. They may also list hardware requirements and discontinuations of older software versions and existing features.

Release notes provide supplements and subsequent information on a specific product release. They are not a replacement for the release notes, but a later addition of relevant points about the release.

Release and Patch

A patch is the publication of a single patch level of an already published release.

genugate 9.0p1 patch

A patch can be applied to genugate and genucenter by means of an update, whereby the update process will always execute all patches one after the other. The procedure is described in the readme for the patch.

For the genuscreen product family, patches can be skipped and the desired patch level can always be selected directly for the update.

For the other products, the procedure is also documented in the respective readme for the patch.

In this context, the terms release and patch refer to the software-related creation and publication process and the type of release. This is different from the categories releases and patches. The latter determine the file type and the usage option with which the software is available.


genuscreen 7.0p0 is the initial release of a new version.

  • It is available in the Releases category as an installation image (CD-ROM and USB stick). This can be used to install the software on empty hardware or to update a running installation to this new version.
  • It is available in the Patches category as a patch image. This can be used to update an existing installation to this version.

genugate 9.0p10 is patch level 10 of version 9.0.

  • It is available in the Releases category as an installation image (CD-ROM and USB stick)

Hardware informations

Hardware information provides an overview of current and older hardware, provides an assignment and allocation of the network interface cards (NIC mask) in the various revisions and models and lists the necessary software versions. In addition, any relevant information for operation is noted.

Certification and approval


genua has some products certified according to international standards in order to prove the quality of the implemented security functions and to be able to use the product in question in environments with the highest security requirements.

Depending on the test, this is done for exactly one version of the software, i.e. version and patch level, and only this is the certified product.


The German Federal Office for Information Security (BSI) issues approvals for IT security products following demand reports from authorities in agreement with the manufacturer.

The approval usually applies to the respective product of a release (regardless of the patch level), taking into account the documents "Design status" and "Application and operating conditions".

Serial number and license number

The serial number uniquely identifies the hardware and can usually be found on the handles on the front of the device.

Muster: 12345-67890-ABCD

The license number allows the use of product-specific software and is usually assigned to a serial number at genua.


In this case, Support can use both numbers to identify the hardware and thus determine the model and revision, as well as the warranty period and possible hardware extensions.

Nevertheless, it is not necessarily possible to deduce the serial number from the license number if, for example, the hardware was not replaced as part of an RMA.


genuscreen product family

The products

  • genuscreen
  • genubox
  • genucrypt
  • genucard
  • genuwall

are all based on the same software and differ in terms of development only in individual details and in terms of content only in the range of functions provided.

The products are therefore combined in some technical areas in the genuscreen product family.

Normally, releases and patches are therefore always published for the entire product family.

Likewise, many articles apply to the entire product family or at least a subset of it.

On the hardware side, however, the genucard differs from the other products; the product is not offered on the usual small and rack hardware, but on special hardware for mobile use on a laptop.

Technical product codes

In technical texts and in the context of software, product abbreviations are often used that cannot always be directly assigned.

The following abbreviations apply:

genugate    GG    G
genuscreen   GS   S
genubox   GB   B
genucrypt   GC   C
genucard   GK   K
genuwall   GW   W
genucenter   GZ   Z
cyber-top   CT    
vs-top   VT    
cyber-diode   CD    
vs-diode   VD    
Cloud Security Gateway   CSG    
GS.Gate   SG    
genua Secure Connector   SR    
cognitix Threat Defender   cTD  


Different spellings for the software versions

In articles, readmes, manuals and other texts, there are always different spellings for the version number.

Example: genucenter version 7.4 patch level 2:

  • Z740_002
  • 7.4p2
  • 7.4 Patch 2
  • 7.4 002

This always refers to the same software version. Backgrounds are often different structures, machine-readable passages or linguistic emphasis.

The following applies:

  • 7: Major Version (M)
  • 4: Minor Version (m)
  • 0: Beta Version (b)
  • 002: Patchlevel (PPP)

Installation, patch and other image files are named according to the scheme ZMmb_PPP.

Z stands for the product abbreviation, Mmb for the current release (consisting of major (one or two digits) and minor version (one digit), as well as a beta version (one digit), which is always 0 for published versions), PPP for the three-digit representation of the patch level for this release.

Readmes and other texts usually use the M.mpP scheme. This means Major.Minor and the patch level is marked with p.

For linguistic emphasis, the spelling with the written-out p is also used for patch.

In some software locations, the scheme M.m PPP can also be found; again Major.Minor and the patch level separated by three digits.

Higher versions such as genugate 10.1 Patch 2 are then written with a two-digit major:

  • G1010_002


Different spellings of the hardware revisions

In articles, readmes, manuals and other texts, as well as in command outputs, there are always different spellings for specifying the hardware revision.

Example genucenter L:

  • Revision 2.0
  • Rev 2.0
  • 2.0
  • 020

The same revision is always meant. This is often due to different structures, machine-readable positions or linguistic highlighting.

The hardware model and revision can be read directly from an appliance:

  • # sysctl genua.hardware
  • # sysctl hw.product hw.version
