Creating a dedicated business email is not only important for your brand, choosing the right service can also help you keep company data secure and comply with data protection laws. Many free email services are not really free because you pay with your privacy. And some of the most popular providers like Gmail or Outlook do not use the strongest available encryption protocols and may share data with third parties.
We built Proton to provide a more secure alternative that uses end-to-end encryption and zero-access encryption by default, which is much more secure against data breaches. Founded by scientists who met at CERN (the European Organization for Nuclear Research) in 2014, today Proton is the world’s most popular encrypted email platform, with over 100 million users, including over 50,000 business accounts.
This article explains how to create a business email address that’s secure by default using Proton Mail, as well as some of its key benefits.

Why use secure email for your business
Most business email providers offer similar productivity features and comparable pricing. But there are major advantages to using a security-first email service.
Prevent data breaches
When you use Proton Mail, emails sent within your organization are end-to-end encrypted by default, meaning the messages and attachments are locked on your device before being transmitted to our servers and can only be unlocked and read by the recipient. For emails to non-Proton Mail accounts, you can send password-protected emails, and zero-access encryption is in place for incoming emails automatically.
In every case, messages are always encrypted on our servers. This means that even in the event of a server breach, your company’s emails remain secure and unreadable to anyone but you, protecting your confidential information from cyberattacks.
Comply with data protection laws
Proton Mail is a GDPR-compliant email service and can also help you comply with industry-specific privacy requirements, such as HIPAA.
Private by default
Platforms such as Google or Microsoft don’t use end-to-end encryption and have access to your company’s data. Therefore, you can’t be sure they won’t someday share your data with third parties or try to otherwise profit off your data. Additionally, because they are based in the US, they may turn your data over to law enforcement upon request.
It’s mathematically impossible for Proton to decrypt your data. And since Proton is based in Switzerland, the little data about you that is collected is protected by Swiss privacy laws and is not subject to foreign law enforcement requests.
Defend against hackers
Proton has several layers of defense against potential cyberattacks:
- PhishGuard: Proton’s PhishGuard filter is designed to identify and flag phishing attempts. When a phishing attack is detected, you will see a warning.
- Two-factor authentication (2FA): Proton Mail offers security beyond just a password with two-factor authentication (2FA). Proton supports several 2FA methods, including authenticator apps and physical security keys, meaning you can choose the most convenient and secure option. With a Proton for Business plan, administrators can also enforce 2FA as mandatory for their organizations to strengthen security among employees.
- Proton Sentinel: This is Proton’s advanced account protection program, which is available with a Proton Mail Professional or Proton Business Suite plan. It is designed to provide maximum security for those who need it by combining AI with human analysis. This is particularly useful if you’re an executive — or someone who deals with sensitive data and communications. Proton Sentinel offers 24/7 support to escalate suspicious login attempts to security analysts.

2. Set up your domain
With a Proton business plan, you have the option to set up a custom domain. This allows your business to maintain branding across all email communications. This step is important because it enhances your organization’s professional image by enabling email addresses at your own domain (e.g., yourname@example.com).
If you don’t have a custom domain, you can purchase one from domain name registrars such as GoDaddy(new window), Namecheap(new window), and Domain.com(new window).
To set up your domain, log in to your Proton Account and click Settings → All settings.
Select Domain Names in the left sidebar. Under Domain names, click Add domain and use the setup wizard to complete your domain configuration.
