Statement on Advanced Electronic Signatures
Impression is proud to announce that it has successfully completed a WebTrust Registration Authority audit. The letters of compliance can be found on our legal repository. It is a key stepping stone in becoming accredited with the South African Accreditation Authority (SAAA) for the issuance of Advanced Electronic Signatures (AES). Impression's WebTrust accreditation should not be confused with SAAA accreditation and although Impression has been widely used to apply AES signatures, it has not yet been accredited to issue AES signatures. For a complete list of AES accredited issuers, please reference the SAAA government website.

Code Signing Certificates
Impression's Code Signing Certificates are used by developers on all platforms to digitally sign the applications and software they distribute over the Internet. Code Signing essentially provides the same assurance as a shrink wrapped CD as the signed code includes the name of the publisher and assurance that the code hasn't been tampered with since being published. Anyone downloading software off of the internet can make a decision whether or not to trust the software.
Multiple Platform Support
Our Signing Certificates support multiple platforms using the same certificate.
Apple Mac OS
Microsoft Office and VBA
Digitally sign Windows 32 and 64 bit files including .exe, .cab, .dll, .ocx, .msi, .xpi, and .xap, ActiveX controls, and kernel software.

Code Signing Certificates for Apple Mac OS are used to digitally sign software, applications, plug-ins, and content for Mac OS desktops. Code signing technology was introduced by Apple for Mac OS 9 onwards.

Digitally sign and encrypt email
GlobalSign PersonalSign Certificates use S/MIME technology to allow users to digitally sign and encrypt email.
Digitally signing an email proves authorship and prevents tampering, assuring the email recipient that the email came from you, not an imposter, and that the content of the email has not been altered in transit.
Encrypting email ensures message privacy and keeps sensitive information from falling into the wrong hands.
Utilizing the S/MIME Protocol provides message integrity, authentication, privacy via data encryption, and non-repudiation via digital signatures. Most mail clients support S/MIME, such as Microsoft Outlook, Thunderbird, Apple Mail, Lotus Notes, and Mulberry Mail.
