Technology
Secure bubble technology is mostly
used by researchers and data scientists to produce
data analysis.
More recently, with the GDPR
and the various CNIL security standards,
the uses of data are developing in
secure and certified environments for
production of data.
The Bubble is a Full Datalab « turnkey »,
with sufficient power and reference software
in a friendly environment,
