- Data ownership. Your data stays on your server, not on Zabbix’s infrastructure.
- Predictable costs. Pay a fixed VPS cost instead of growing per-user or per-usage fees.
- No vendor lock-in. Export and migrate your data anytime. You control the database.
- GDPR and compliance. Hosting your own tools simplifies data residency and compliance requirements.
