DigiCert S/MIME

DigiCert SSLDigiCert S/MIME certificate is a highly advanced solution for securing electronic communications, designed for organizations that require the highest level of data protection and authenticity of transmitted information. Based on the Secure/Multipurpose Internet Mail Extensions (S/MIME) standard, this certificate enables both encryption of e-mails and their digital signing, which ensures confidentiality, integrity and verifiability of content. By using strong cryptographic algorithms, such as RSA with a minimum key length of 2048 bits and ECDSA, the DigiCert S/MIME certificate guarantees resistance to modern cryptographic threats, while ensuring high efficiency and security of data transmission. The certificate issuing process includes rigorous verification of the user’s identity, which increases the recipients’ confidence in the authenticity of the message sender. DigiCert uses advanced authentication procedures, compliant with international security standards, which makes the certificate suitable for sectors such as finance, healthcare, public administration or law, where data protection and compliance with legal regulations are key.

Integration of the certificate with popular email clients such as Microsoft Outlook, Apple Mail or Mozilla Thunderbird is seamless thanks to its compatibility with a wide range of protocols and standards. Intuitive certificate management tools enable easy configuration and central management of cryptographic keys, which minimizes the time needed for implementation and ensures consistency and security in large IT environments. Additionally, the certificate supports features such as automatic renewal, status monitoring and security policy management, which makes it easier to administer and maintain certificates on an ongoing basis. DigiCert S/MIME also integrates with document management systems and office work tools such as Microsoft Office or Adobe Acrobat, enabling digital signing of electronic documents. This functionality is essential in business processes that require strict control over the authenticity and integrity of documents, while ensuring compliance with international regulations such as eIDAS in the European Union. A digital signature made using a DigiCert S/MIME certificate guarantees that documents have not been changed after they have been signed, which is crucial for auditing and compliance with legal requirements.

DigiCert S/MIME certificate uses a public key infrastructure (PKI), which enables effective management of digital identities in the organization. Central certificate management allows for easy scaling of the solution as the organization grows, while ensuring a high level of security through advanced access management mechanisms and regular security audits. DigiCert, as a leader in the field of digital security, guarantees the highest quality of its products, providing users with reliability and compliance with the latest industry standards.

Organization Validation (OV) SSL Certificate

The validation procedure for the DigiCert S/MIME certificate is a multi-step process designed to ensure the highest level of security and trust in electronic communications. The first step is to submit a certificate application by the user, who can be either an individual or a representative of an organization. In the case of companies, DigiCert requires the provision of documentation confirming the identity of the company, such as an entry in the register of entrepreneurs, and identification documents of persons authorized to manage certificates. Then, DigiCert conducts a thorough verification of the applicant’s identity. In the case of certificates for organizations, this process includes verifying the information provided in the application by contacting official sources and confirming the existence and legality of the company’s activity. For individuals, verification may include confirming identity using documents such as an identity card or passport, as well as checking the authenticity of the data provided. The next step is the generation of a cryptographic key pair by the user, which is the foundation of the security of the S/MIME certificate. The private key remains in the user’s possession and is used to sign and decrypt messages, while the public key is contained in the certificate and made available to recipients of messages to verify the signature and encrypt the response. Once the verification process is complete, DigiCert issues an S/MIME certificate, which is then installed in the user’s email client. The installation process is supported by DigiCert by providing the necessary instructions and tools that allow for smooth integration of the certificate with popular email applications such as Microsoft Outlook, Apple Mail or Mozilla Thunderbird. At this stage, the public key is made available to recipients, allowing for secure and authentic electronic communication. The entire validation process is compliant with international security standards and legal regulations regarding data protection, making the DigiCert S/MIME certificate a suitable solution for sectors requiring the highest level of information protection, such as finance, healthcare or public administration. Thanks to rigorous validation procedures, DigiCert ensures that S/MIME certificates are issued only to trusted users, which significantly increases the level of security and trust in electronic communication.
