Products
Two products, developed in Europe. Crystallis protects the links of critical infrastructure. TAC compresses and verifies archives and data series.
Crystallis
The protected link, agent to agent
An agent at each end of the link and a management centre that decides who talks to whom. Zero Trust on every link and X25519 + ML-KEM-768 hybrid key exchange: complete security, resistant to quantum computers.
Agents at both ends
They install next to existing systems, on standard hardware. Applications and plants stay as they are.
An identity for every device
Each device has its own key, generated on the device. The link opens only after mutual recognition.
A permission for every service
Microsegmentation applied to links: each device reaches only the services written in its rule.
Management centre
It governs identities, permissions and exclusions. It sets the rules and never sees the data.
Signed log
Every event leaves a signed trace showing who talked to whom, and when.
Signed updates
They are verified before activation and roll back on their own if the test fails.
TAC
Archives and data series, compressed and verified
TAC compresses, opens, verifies and extracts archives. It creates its own format, .adpx, and also opens ZIP, 7z, TAR and GZIP files, which it recognises by their content.
Safe extraction
An archive from outside cannot write beyond the chosen folder: symbolic links are never followed, and every file is either written whole or rejected.
Check before you open
Archive integrity is checked without writing anything, and you know in advance what it contains and how much space it needs.
Recovery after interruption
A recovery journal protects long operations from shutdowns and failures.
Numeric series
Dedicated interfaces compress series of integers and decimal numbers, such as measurements and telemetry.
Fully local
TAC contacts no external service: data stays on the computer it runs on.
Three ways to use it
Application
Compress and open archives from the desktop, in five languages.
Command line
For automation, with a distinct exit code for each kind of outcome.
C libraries
Bring TAC into other programs, with no external processes.
For data travelling between sites, there is Crystallis.
