FAQ
What does PAC cost?
PAC is completely free of charge for all types of applications.
Is PAC also approved for commercial applications and free of charge?
Yes, as long as you comply with point 7.2 of our General Terms.
Is there a Mac version of PAC?
No.
A Mac version is in the works (release not before 2026), but there is currently none.
Is there a penetration test for PAC?
Penetration tests are useful for server applications (e.g. a web service) that can be accessed from the Internet. In the event of a penetration, an attacker can gain unauthorized access to local resources.
PAC runs as a desktop application on a local computer and neither makes contact with the Internet nor can it be accessed from outside. In this sense, PAC cannot be penetrated and therefore there is no penetration test.
Is there a software security check for PAC?
axes4 places the highest priority on strong security standards. We follow comprehensive security guidelines that cover physical device access, data protection, and many other areas. However, since PAC has no connection to the Internet and is not accessible from the outside, potential security vulnerabilities – should they occur despite these guidelines – cannot be exploited. Therefore, an expensive external security audit is as unnecessary as a penetration test.
Does PAC run under Citrix, Terminal Server and similar systems?
Yes.
Is there an installation file (*.msi)? How can I roll out PAC to many people?
We currently only provide PAC as a ZIP file, so there is no MSI.
You can download the ZIP file, unzip it into a folder and distribute this folder using the usual deployment tools (Active Directory etc.). However, it is essential that you observe point 7.2 of our General Terms.
The PDF/UA and WCAG checks show green checkmarks, but the quality checks do not ‒ is this relevant for me?
See our explanations on the quality checks.
Is the test result legally compliant and does it guarantee absolute accessibility?
The PDF Accessibility Checker PAC is the globally used tool for checking accessible PDF files and has been established since 2010. It supports both the DIN/ISO standard PDF/UA and the WCAG (Web Content Accessibility Guidelines). Not all requirements of both standards and guidelines can be checked automatically by software. Additional checks by a human are always required, for example to determine whether the semantic markup is appropriate. The test result can therefore not be legally binding, but it is an indicator. If all the check marks are green on the PDF/UA and WCAG tabs, this only means that all automatically checkable requirements have been met.
