Important
A sentinel, not a backup.
NAS Sentinel alerts you and helps you interpret the available signals. It does not replace a verified backup, human oversight, or your NAS manufacturer’s recommendations.
Answers before questions.
Does NAS Sentinel use a cloud service?
No. Monitoring works directly between your NAS and your Mac. No NAS Sentinel cloud backend is required.
Do I need to provide a NAS administrator account?
No. NAS Sentinel does not request a NAS administrator login. Sensitive SNMP information is protected using macOS Keychain.
Can I monitor several NAS devices?
Yes. The trial and Pro edition support up to five NAS devices from the same Mac.
Can I monitor remotely?
Yes, through a private connection you control, such as Tailscale or a suitable VPN. SNMP should never be exposed to the public Internet.
Which NAS devices are compatible?
NAS Sentinel is compatible with Synology NAS devices depending on the model, with supported DSM 6.x and 7.x versions. Many additional platforms are planned for the future. With NAS Sentinel Discover Engine, heterogeneous monitoring will be possible directly from your Mac.
