🛡️ Backup operated with WeDoBack
Klytic relies on the services of WeDoBack, a specialist in secure backup. Your data is not just copied: it is encrypted, replicated across multiple sites, and protected against deletion as well as ransomware.
🔐
Backups are encrypted: even if support is accessed, the data remains unreadable to a third party.
🏢
Your data exists in multiple copies, in distinct locations: an incident at one site does not affect your backups.
🧱
A written backup cannot be modified or deleted, even by an attacker: ransomware cannot reach it.
👁️
Backups are continuously monitored: a failure is detected and addressed without waiting for you to need it.
♻️
From an accidentally deleted message to the full recovery of a service, restoration is part of a business continuity plan (BCP) and disaster recovery plan (DRP).
✅
Services compliant with GDPR, ISO 27001 standard, and HDS certification for health data.
