Encryption

Confidential content is protected by fully automated end-to-end S/MIME encryption.
Your sensitive information remains unreadable to third parties throughout the entire transmission.

Hosting & Compliance

All data is processed and stored exclusively in German data centres in accordance with the highest security standards – including GDPR compliance, regular backups and professional monitoring.

Managed Security Service

groupios Gateway
for Microsoft 365®

Maximum security for your Microsoft 365® environment: The groupios Gateway is connected to your Microsoft® services as a central, professionally managed protection instance and acts as an intelligent security gateway for all your email communication.

Ideal for companies that use Microsoft 365®
and are looking for a professionally managed security solution
without the need for their own IT resources.

How it works:

The groupios gateway supplements the security features of Microsoft 365® with various layers of protection – fully managed by our team of experts. Every incoming and outgoing email first passes through the groupios gateway before reaching or leaving Microsoft 365®. There, threats are detected and neutralised before they can even reach your mailboxes.

Managed Encryption Service, Optional

S/MIME-Encryption

Protect your corporate communications with professional encryption technology – fully managed and with no effort required on the part of your users. Our S/MIME solution for the groupios gateway secures your messages and confirms your identity to the recipient as trustworthy.

Ideal for companies and public authorities with high security requirements that exchange sensitive information such as financial data or health records via email – fully supported and with no technical effort required.

How it works:

The groupios gateway signs and encrypts your emails centrally and fully automatically, immediately before they leave your digital territory. This makes you independent of the security of external infrastructures: unlike pure transport encryption (TLS), the protection is firmly linked to the message itself. Your content remains confidential and tamper-proof, even if the communication partner's servers or intermediate stations are compromised.

Your S/MIME advantages at a glance

Key Harvesting

The system learns as it goes. Public keys from incoming, signed emails are automatically recognised and stored. This means you can immediately reply to communication partners in encrypted form.

Intelligent confidentiality

As soon as the recipient's key is available, email content and attachments are encrypted fully automatically. This allows you to effectively protect sensitive data from unauthorised third parties.

Consistent authenticity

Digital signatures guarantee the recipient beyond doubt that the message really comes from you. This validation protects your reputation from spoofing and identity theft.

Security as a managed service

The private keys are stored securely on the groupios gateway. Since no sensitive key material is stored on end devices, you minimise the risk in the event of device loss or theft.

No effort required by users

You decide which certificate provider you want to use. The groupios user interface allows you to centrally upload and manage certificates from any issuer (CA) – you are not tied to any specific reseller.
