The Investment Center [Blackbird Group] is included in the list of the Ministry of Digital Governance (APED - Hellenic Public Administration Certification Authority) as all digital certificates that have been issued, have been received and have been verified to work correctly with the infrastructure of the Ministry (APED).


In the last 6 years, our company has undertaken a number of installations of USB TOKENS for cases where the use of a Digital Signature is mandatory, such as:

  • in Public Electronic Tenders in order for a company to participate (ESIDIS, cosmoONE, iSupplies).
  • in professional categories such as Engineers, Pharmacists, Doctors, Lawyers, Notaries, Realtors, Economists.
  • in cases of Public Organizations such as Public Service Employees, Elected Officials, Educators.
  • in cases of mandatory use of the Digital Signature, such as the Development Law.

Having the experience of more than 8,000 installations, we recommend the optimal solution - cost [value for money]. Ask us which USB TOKENS we recommend, which ones have been tested, as well as which Digital Signatures work smoothly.
