FLAM: sovereignty score and 8 European alternatives

FLAM (Frankenstein Limes Access Method) is software from limes datentechnik gmbh for compressing, encrypting and archiving data. It runs on mainframes (z/OS) and on Windows, Unix and Linux servers. FLAM encrypts at column level, including with AES, and protects data integrity. Archives stay searchable and editable (insert, update, delete, search) without unpacking the whole file, and data can be provided as XML, JSON or CSV. Archives work with local storage and with cloud storage such as Amazon S3, Azure and Google Cloud. Applications connect through APIs for COBOL, Java, C or PL/1, or through a subsystem on z/OS.

limes datentechnik gmbh is based in Bad Homburg vor der Höhe, Germany, and has been in the commercial register since 1985; its website names no parent company. FLAM is software that you install and run yourself, on your own systems or in storage of your choice, and you manage the keys through two-level key management. For European organisations with mainframe environments this is a German vendor with a product you operate yourself. No open-source code is mentioned.

Why digital sovereignty matters with FLAM

FLAM is headquartered in DE and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

FLAM runs on infrastructure you choose and control yourself. You decide where the data lives, including fully within the EU if you want — this is not a fixed hosting choice made by the vendor.

FLAM is closed source, but you run the software yourself on your own infrastructure. The encryption keys and the runtime therefore stay under your own control, though you cannot audit or modify the source code. Ask about export options and open standards to limit software-level lock-in.

What this means for your organisation depends on your whole stack and context. The free assessment weighs FLAM together with your other vendors and gives a total score, a heatmap and the main risk drivers.
