You may choose among the following options according to your needs:

• Get a Server Certificate (SSL/TLS) for one or more websites of your organization, to protect the authenticity of each website and the protection of their visitors, so they can exchange data in a secure, encrypted way.  
• Get Electronic Signatures for your staff/employees so they can sign legally binding documents and participate in public or private tenders in Greece or the rest of the European Union Member States.
• Secure the identity of your organization by using an Electronic Seal which is equivalently legally binding with an Electronic Signature.
• Get a Code Signing Certificate to digitally sign any software product you produce, so that it is trusted by end-users.
• In case all your staff members or employees have an email address under the same domain or if you require a large number of server (SSL/TLS) certificates under specific domain names, then you may obtain your own “Certification Authority” so that all end-entity Certificates (websites, eSignatures, etc) will have your Organization/Enterprise name as the “Issuing Authority”. The Administration/Management of this Certification Authority will be performed by HARICA.
