Certum

Certum is a European trust services provider that specializes in digital security and electronic signature solutions, offering tools designed to streamline secure document workflows and cryptographic authentication. Its flagship offering, proCertum SmartSign SimplySign Desktop, combines two complementary modules: proCertum SmartSign for creating, timestamping and verifying qualified electronic signatures within popular document formats, and SimplySign Desktop for emulating a cryptographic smart card so users can store certificates on a local drive instead of physical hardware. Together they enable lawyers, accountants, civil servants and remote teams to sign contracts, invoices, tax filings and official submissions with full legal validity under eIDAS, while eliminating the need for dedicated card readers or token devices. The suite integrates with Microsoft Office, Adobe Acrobat and common e-mail clients, allowing batch signing, visible graphical seals and long-term validation (LTV) to ensure files remain verifiable decades later. Typical scenarios include CFOs countersigning annual reports, notaries issuing authenticated deeds, HR departments onboarding employees with digitally signed contracts, and developers code-signing software releases. By centralizing certificate management in a single desktop agent, Certum simplifies deployment across corporate laptops and virtual desktops, supporting both qualified and advanced signatures depending on the assurance level required. The publisher’s software is available for free on get.nero.com, where downloads are supplied through trusted Windows package sources such as winget, always delivering the latest versions and permitting batch installation of multiple applications.
