There are two quality levels to cover different target groups. The quality levels differ regarding their security claim as well as the assurance level.
The basis label addresses primarily smaller companies and organisations. It comprises 14 baseline security requirements, which any organisation should be able to fulfil; the effort is reasonably limited. The assessment is based on a validated self-declaration. The process is therefore simply and fast.
The advanced label is geared towards larger enterprises and organisations which want to (or have to) fulfil a higher security level. It comprises the 14 baseline security requirements plus 11 additional requirements. To comply with this standard, organisations need preparation and a certain effort accordingly. The assessment is based on a third-party audit. This process takes some more time but can also be completed in a few weeks.
