Local DLP vs cloud DLP
The biggest choice in data loss prevention is where the scanning happens. Here is how on-device and cloud DLP differ, and when each makes sense.
Where the scan runs
The core trade-off
Cloud DLP analyses your data on a provider’s infrastructure, which enables organisation-wide policy across many services, at the cost of sending your content there. Local DLP analyses data on the device, keeping it in place but scoped to that machine.
Neither is universally better. The right choice depends on what you are protecting and who needs to see the results.
Side by side
Local vs cloud DLP
| Dimension | Cloud DLP | Local DLP (FileSentinel) |
|---|---|---|
| Where data is scanned | Provider infrastructure | On your device |
| Data exposure | Content sent to the cloud | Nothing uploaded |
| Scope | Org-wide, many services | The machine and its shares |
| Setup | Tenant, policies, agents | Install one app |
| Best for | Large orgs with cloud estates | Privacy-sensitive, SMB, individual use |
When local wins
Keep sensitive data in place
For regulated, confidential, or personal data, the appeal of local DLP is simple: the data you are protecting never has to leave to be checked. FileSentinel is built that way, with all scanning and remediation on-device.

Questions & answers
FAQ
Is local DLP safer than cloud DLP?
For the data being scanned, local DLP avoids the exposure of uploading it. Cloud DLP offers broader, centralised coverage. The safer choice depends on your data and obligations.
When does cloud DLP make more sense?
When you need organisation-wide policy across many cloud services and have the team to manage it. Local DLP suits machine-level, privacy-sensitive scanning.
Where does FileSentinel sit?
It is a local, on-device DLP scanner for Windows, with no uploads, aimed at individuals and small teams.
Can I use both?
Yes. Many organisations use cloud DLP for breadth and a local tool like FileSentinel for sensitive endpoints and pre-share checks.
