Who Is Digital Signature For?

Digital signature for businesses

A business digital signature is an electronic signature that holds the same legal validity as a company seal. Today, it is widely used as a secure authentication technology, ensuring the safety and legality of transactions conducted over the Internet.

Digital signature for individuals within organizations

This type of digital signature is created by individual users within companies or organizations. It functions as a legally recognized signature for individuals or as an equivalent to a corporate seal. It is one of the most effective solutions for secure online transactions and is also widely applied in various high-security sectors.

Digital signature for independent individuals or household businesses

This signature is issued to individual users who are not part of any organization or company. It carries the same legal weight as a handwritten signature in electronic environments and is ideal for personal or household business use.
