Who are we?

MeSign Technology Limited is registered in Shenzhen, the city of innovation and vitality, located in the Greater Bay Area of South China. Shenzhen office is the operation and R&D headquarters. In addition, MeSign Technology Limited is registered in Hong Kong SAR and the UK as wholly owned subsidiary of MeSign Shenzhen. Shenzhen company is responsible for providing high quality services to Chinese users, Hong Kong SAR and UK companies are responsible for providing high quality services to worldwide users except China mainland. MeSign Technology has a group of top technical experts who have drilled in the field of PKI technology for more than ten years and are committed to providing global users with high-level information cryptography products and solutions based on PKI technology.

MeSign Technology is a data security products and services provider with cloud computing service capabilities and publicly trusted root CA certificate (WebTrust audited), which not only empowers our own developed client software to achieve automated digital signatures, encryption and timestamping, but also provides cloud cryptographic services to empower all software and Internet applications, and popularize and promote the use of digital signature and encryption technology to ensure Internet data security.

What do we do?

MeSign Technology has built a cloud cryptographic infrastructure, enabling the self-developed client software-MeSign App to realize automatic email encryption and automatic document digital signature. And we provide cloud cryptographic services, make our cryptographic capabilities as a service to empower all software and Internet applications to utilize the cryptographic technology to protect all data security. All our solutions are based on the concept of Zero Trust security, using PKI technology to protect information systems security and data resource security.

How are we doing?

MeSign APP users have covered 161 countries and regions around the world and continue to be popular among global users. It has provided three versions including Windows, Android and iOS, and plans to release MacOS and Linux versions, supporting 15 languages. MeSign Cloud Cryptographic Service has also helped many Internet service providers around the world protect valuable data resources. MeSign Zero Trust Security solutions have not only been successfully applied in email security and document security, but have also begun to be applied in IoT security and industrial Internet security.

How did we do it?

We have invested 5 years in research and development, invested in the construction of a secure and reliable encryption service infrastructure-MeSign Cryptographic Infrastructure, and shared these facilities with all MeSign users around the world, so that everyone doesn’t need to have the necessary trust infrastructure in place but can also implement email encryption, document signature and data encryption, to meet various compliance requirements.

MeSign Cryptographic Infrastructure consists of seven service systems: MeSign Certificate Authority (MCA), MeSign Cryptographic Key Management System (MKM), MeSign Public Key Exchange System (PKE), MeSign Certificate Revocation Status System (MCR), MeSign Identity Validation System (MVS), MeSign Timestamp Service System (MTS), MeSign Digital Signature Service System (DSS) and MeSign Encryption Service System (MES). These service systems in cloud work together with MeSign APP (email client APP) to constitute the "Cloud" and the "Client" collaboration system to provide the secure and reliable email encryption service and e-document signature service automatically for worldwide users. In other words, MeSign APP is not a traditional independent email client software or an e-signature tool software, it is a user-oriented service agent which not only let users handle their own data locally to protect privacy, but also let users utilize the powerful cloud service for automatic email encryption and automatic document digital signature. And the cryptographic capabilities of MeSign Cryptographic Infrastructure provide software developers and Internet service providers with the digital signature, encryption and time stamping services to protect business data in the form of cloud cryptographic services.

What else do we do?

In order to promote the global popularization and application of cryptographic services, MeSign Technology grandly launched the Global Partner Eco Program, which open its cryptographic infrastructure to global application software developers and Internet service providers partly free and partly paid to provide data security and privacy protection for global users, together truly and fully realize the end-to-end full encryption of all information and data, and fully protect user privacy, commercial secrets and Internet big data, making the Internet more secure to serve all mankind.
