250,000 euros. This is the amount of the fine imposed by the Commission Nationale de l'Informatique et des Libertés (French Data Protection Authority or "CNIL") on Optical Center, a French company specialized in optics, for having failed to properly secure its website www.optical-center.fr.

The CNIL immediately initiated a sanction procedure against Optical Center.

It is interesting to note that Optical Center complained about the lack of any prior formal notice which it considered as a "substantial component" of the procedure to ensure due process and respect of the rights of the defense.

The CNIL simply swept aside this argument as...
