e-SignIT flow


e-SignIT is provided as a service through ADACOM's secure and certified facilities, or it can be installed on the customer's premises.

The solution is certified according to EU standards (CWA 14167-1) and Common Criteria EAL4+ (EN 419 241-2 Protection Profile). Additionally, the solution is certified as part of the US government FIPS 201, FPKI Path Discovery, and Validation (PD-VAL) programs.

The EU eIDAS Regulation enables qualified e-signatures to be legally accepted as equivalent to handwritten ones across the EU. Remote qualified signing refers to the fact that eIDAS also allows signatures to be created remotely with the user’s signing keys, also known as central signing, server-side signing or cloud signing. The below diagram describes the whole signing process through e-SignIt.
