Your questions answered
What is Zimbra?
Zimbra is a secure and collaborative email solution, designed for both professionals and individuals. It brings together your emails, contacts, calendars, tasks, and files (depending on the plan) in a user-friendly interface, accessible from all your devices. Hosted in France, Zimbra ensures the confidentiality of your exchanges and the sovereignty of your data.
How does Zimbra ensure email privacy?
Each message is protected end-to-end, from sending to archiving, thanks to TLS protocols and directory encryption. Zimbra servers are installed on hardened operating systems to block any intrusion attempts. Ongoing 24/7 monitoring and automated detection tools also ensure active protection against attacks, keeping your communications private at every stage.
How does Zimbra store my data?
All your data (emails, attachments, contacts, calendars, and files) is hosted exclusively in OVHcloud French datacentres. This means your data is not subject to extraterritorial laws, such as the CLOUD Act, while also being fully complaint with the GDPR. Your data is protected by European law and completely under your control.
How does Zimbra differ from other email services?
Zimbra combines sovereignty, security, and transparency. Both our internal teams and independent experts routinely assess the robustness of our protections. We install security patches as soon as they are released, and our partnership with the Signal Spam community continuously strengthens the reliability and security of your emails. This way, you can benefit from a professional, secure, and sustainable email service.
Besides encryption, what other security measures are used?
Zimbra incorporates several advanced protections:
- multi-factor authentication (MFA) improve the security of connections;
- daily backups allow you to restore your messages for 14 days;
- integrated antispam and antivirus protection blocks threats before they reach your inbox;
- SPF, DKIM, and DMARC protocols verify senders and prevent identity theft.
These measures combine to provide ongoing security without impacting performance or ease of use.
How does Zimbra ensure the availability of my services?
Zimbra relies on a redundant and highly available infrastructure that is consistently monitored by our teams. Security patches and updates are applied as soon as they are launched, without service interruption. This provides you with a reliable, high-performing, and secure email service, tailored to the needs of businesses of all sizes.
