Luottoposti was born from a need and grew into a service
Luottoposti's services were developed from our company's own needs
We needed a secure way to send confidential information electronically, but we discovered that there was no solution on the market whose encryption we could fully trust throughout the entire transmission process. As an IT company, we decided to solve the problem ourselves and developed our own system. The result was Luottoposti, a secure encrypted email service where privacy and data security come first. Luottoposti has been awarded the Key Flag Symbol in recognition of Finnish work, a domestically produced service, and operations worthy of customers' trust.
Initially, we developed the service for our own needs, but we quickly realized that many of our customers needed a similar solution. This led to the commercialization of Luottoposti, and today our customer base is growing rapidly. We already have many satisfied customers, and new ones continue to join us.

Why is secure email communication important?
Encrypted email is an essential part of responsible operations. When communications are secure, activities can be conducted openly and safely without concerns about data breaches or misuse.

Protection of personal data is essential
The Constitution of Finland (Section 10) establishes the protection of personal data by law. Data protection legislation requires special care in the processing of personal data. The Data Protection Authority has defined specific obligations regarding due care, data protection, and information security for companies when processing customers’ and employees’ personal data. Messages containing personal data must be protected. In addition, similar protection obligations also apply within the social and healthcare sector, including the processing of customers’ names alone.

Your email communications can be intercepted
For example, unencrypted emails routed through Sweden or the United States may be subject to monitoring conducted by government authorities.

Are your emails protected by the secrecy of correspondence?
Unencrypted email cannot unequivocally be regarded as a closed or protected message, as its contents may be exposed unintentionally, for example to individuals monitoring network traffic. From an information security perspective, an unprotected message can be compared to a postcard, where the contents are openly visible to anyone.

Encrypted email provides constitutional protection.
Email encryption means that the contents of an email message are transformed into a protected code that can only be read using the recipient’s password and decryption key. This means that only the recipient can read the contents of the email message.
Especially when the content of the email is confidential or personal,such as information relating to health status, bank account details, or personal identity numbers, it is extremely important to encrypt email in order to protect privacy and prevent misuse of information.
In a highly secure encrypted email solution, the message is stored on a protected server that delivers the keys required to read the message to the recipient through separate communication channels. Therefore, Luottoposti™ is an ideal solution for your needs.
