Encrypting email messages in Outlook ensures the security of corporate correspondence 

Why is encrypting email messages in Outlook so important?

Secure communication within the company is a crucial element for the efficient functioning of the organization. This is especially important in the era of increasing cybersecurity threats. It is also a priority point in the information security strategy. It has a fundamental impact on the confidentiality and efficiency of the entire organization’s work. Employees send hundreds of emails daily, containing crucial data such as business strategies, development plans, or financial information. Secure communication is a crucial aspect of preventing unauthorized access to this information. Protection of corporate mail can be achieved through encryption of e-mail messages.

The safest email solution is Certum S/MIME

S/MIME Certificates (Secure/Multipurpose Internet Mail Extensions) are one of the simplest and most effective methods for email protection. By enabling the signing and encryption of email messages, S/MIME certificates verify the sender’s identity. Their purpose is also to secure the content against unauthorized access. Additionally, they confirm the integrity and authenticity of the messages, thus preventing phishing attacks and minimizing the risk of impersonation of employees.

How to implement message encryption in Outlook using Certum S/MIME certificates?

Protecting official correspondence is a pillar of secure communication. The best and easiest form of security is to encrypt email messages using Certum S/MIME digital certificates. S/MIME encryption is a safeguard against unauthorized access attempts and an effective method to prevent the loss or modification of important information sent in e-mails. Well-implemented encryption ensures that the message content remains unreadable to unauthorized individuals, even if the transmission is intercepted. Moreover, in the context of legal regulations concerning personal data protection, S/MIME helps meet the requirements related to information privacy. Companies are often obligated to secure personal data, and employing encryption in corporate email is an effective measure to comply with GDPR regulations. The implementation of S/MIME certificates is particularly crucial in business, where confidentiality and integrity of transmitted information matter. It is also essential for complying with data security regulations.

Signing and integrity of email messages

Another element of secure communication is enabling employees to easily verify the email sender. Signing messages using the S/MIME standard plays a crucial role in preventing phishing. It allows recipients to quickly verify if an email indeed comes from the legitimate sender. If an email is digitally signed, the recipient can verify the authenticity of the signature, serving as irrefutable proof that it was sent by the actual person or institution. If an attempt to modify the message content during transmission occurs, such as in a man-in-the-middle attack, the digital signature becomes invalid. This is a clear signal of potential risk. Applying S/MIME for signing and encrypting email messages in companies ensures the protection and integrity of messages, strengthening a secure environment for corporate communication.

How to establish message encryption in Outlook throughout the entire company?

Encrypting and signing email messages is most effective when all employees in the company have implemented S/MIME certificates. Implementing individual S/MIME certificates requires significant effort. Generating, managing, and updating many, sometimes thousands, of certificates is time-consuming. Therefore, it is valuable to implement a mechanism that allows the swift generation and delivery of certificates to all employees in the entire organization. The Certum Enterprise ID application enables group ordering and activation of Certum S/MIME certificates. The application’s simple and intuitive interface facilitates the rapid and efficient implementation of certificates throughout the organization and email domain. This saves time and effort.
