7 reasons your business needs to encrypt its communications

1. Prevent falling victim to a data breach

Without end-to-end encryption, your mailbox is accessible to the provider thus a lot less secure and not private. As companies deal with confidential matters such as financial documents, employee data, or customer data via email, ensuring it doesn’t fall into the wrong hands must be a priority. With truly secured and private communications through end-to-end encryption, companies greatlyreduce the risks of data being exposed in a data breach.

In addition to choosing a mail provider that offers a zero-knowledge architecture, and encrypts as much data as possible, it’s also advised to choose an email service that offers additional security measures like additional login protections using two-factor authentication (2FA). All of these extra layers of security, help reduce the risk of confidential data or employee login credentials getting leaked online.

Tuta Mail is a perfect example as it combines all these factors and already offers quantum-safe encrypted emails. When companies choose Tuta Mail they are guaranteed that their email is protected from future threats.

2. Keep confidential communications truly private

Popular big-tech email providers like Gmail or Outlook do not end-to-end encrypt emails by default. These providers, usually encrypt your email while in transit, but the emails are still accessible as clear to the provider – meaning they can be read by external parties. If it is possible for emails to be accessed by unintended parties you cannot ensure it remains truly private and the risk of emails falling into the wrong hands is greater.

That’s where end-to-end encryption comes in.

When you use email with end-to-end encryption, then only the sender and the recipient who have the decryption keys can decrypt the email and access its contents.

When companies opt for an email provider, like Tuta Mail they are guaranteed that business matters remain truly private and confidential. Tuta end-to-end encrypts more data than any other email provider, and it only stores encrypted data on the servers based in Germany.

3. Ensure customer data remains secure

For companies in industries that deal with client data and private information like medical records or banking documents, ensuring that the customer’s information is stored and sent securely is mandatory. Without end-to-end encryption, companies cannot guarantee the highest degree of security and privacy for user data.

4. Regulatory compliance: GDPR / HIPAA

Companies have regulatory standards set in place to protect user data and privacy. In addition, businesses must comply with regulations depending on where they are based, for instance with the GDPR or HIPAA. These regulations define how a company must handle, transmit, and store personal data. These regulations are different for each country and industry.

As a company, you have to comply with these privacy protections, which often require companies to use encryption protocol. In Europe, the General Data Protection (GDPR) ensures that companies operating within the EU adhere to strict security and privacy standards when it comes to handling user data. In the United States, the Health Insurance Portability and Accountability Act (HIPAA) is an act in place that aims to keep medical data safe and ensure data privacy.

If a company chooses Tuta Mail as its encrypted business email, it can have peace of mind that its email is in compliance with the EU’s GDPR.

5. Increase company image and reputation

It’s no secret that companies are at high risk of being targets of cyberattacks. One way to reduce the risks of a company falling victim to a data leak or hack is to ensure you have a robust mail solution that uses the highest security and privacy standards.

An easy investment of migrating to a privacy-focused, mail provider with end-to-end encryption might sound unnecessary, but when it comes toprotecting your company image and reputation it truly is worth it.

Additionally, through using an email provider known for its encryption and privacy you build a positive brand image and trust with others you communicate with. This is especially important forgaining consumer trust when it comes to sending sensitive information via email.

6. Reduce data collection

For business and personal use when it comes to email or any other online service, it’s always worth remembering that popular big tech services like Google make their profits from advertising. In short, they follow your online movements, collect a lot of user data, and sell it to third parties who in return target you with ads.

Any company wouldn’t want its private accounts to be snooped on, or for any kind of data to be collected. That’s why by opting for an end-to-end encrypted email provider,much less data can be tracked and collected.

If you opt for a business email address with Tuta Mail, your company benefits from the email provider’s strong focus on data minimization principles.

7. Minimize risks of human error

As a company, it’s important to make your workforce aware of the cyber risks that could potentially lead to problems in operations, negatively affect your brand, or user trust. Unfortunately, human error will always be a risk that companies need to consider, especially when phishing emails can seem so real and hard to distinguish.

As a company, one way to reduce the risk of human error causing problems is by choosing an end-to-end encrypted email provider. Because of the E2E encryption, any sensitive information in the email is best protected.
