Stage 01
Identify shared storage
File servers, NAS systems, and team network shares form the protected data layer.

Ransomware protection for shared files
Stop suspicious writes at shared storage
Network Share Protection monitors write activity targeting file servers, NAS systems, and network shares. When behavior associated with ransomware encryption appears, malicious write operations are blocked.
Stage 02
Monitor write activity
File-write operations from managed and unmanaged devices are monitored in real time.
Output: Write activity across shared storage
Stage 03
Check for encryption patterns
Write operations are analyzed for behavior associated with ransomware encryption.
Output: Suspicious behavior signal
Stage 04
Block malicious writes
Suspicious file-write operations are blocked; policy and visibility are managed through the Xcitium platform.
Output: Blocked operation and protected files

Capabilities
Capabilities with a specific purpose
Shared-file write analysis
Monitors write activity on file servers, NAS, and network drives for ransomware encryption patterns. The control is focused on shared storage.
Suspicious write blocking
When suspicious behaviour is detected, write operations that could alter or lock shared files can be blocked. Test exceptions and application impact.
Coverage for unmanaged devices
Network Share Protection monitors writes to shared files and can block suspicious operations during attacks originating from contractor laptops, BYOD, and legacy endpoints.
File servers, NAS, and network drives
The control is intended to protect file integrity on shared storage used across teams. Establish supported protocols, storage platforms, and required configuration in a pilot.
Complement endpoint controls
Endpoint protection monitors processes on a user device, while Network Share Protection monitors writes at the shared-file layer. Assign alert and blocking ownership for each control.
Compare approaches
Shared storage and endpoint controls
| Consideration | Network Share Protection | Endpoint EDR |
|---|---|---|
| Protected object | Shared files on network drives and NAS. | Processes and events on an endpoint with an installed agent. |
| Detection signal | Ransomware encryption patterns in file writes. | Process, file, and behaviour telemetry on the device. |
| Primary response | Block suspicious writes before shared files are changed. | Detect and investigate suspicious activity on the endpoint, then contain it. |
| Good fit | Protect network storage from unmanaged sources. | Detect and investigate activity on the endpoint. |
Before you start
Plan a shared-file pilot
Test normal write activity and blocking on one file server or NAS share. Agree on user impact and recovery procedures before rollout.
- 01
Which servers, NAS systems, protocols, and shares are in scope?
- 02
How will legitimate bulk edits, backup, and encryption tasks be handled?
- 03
Who handles application and user recovery after a block?
Evidence for your evaluation
In practice
Protecting shared folders
A contractor’s unmanaged laptop connects to a shared file server. Suspicious mass writes can be monitored at the share even when the originating device is outside endpoint-agent coverage. The storage administrator can review the event alongside endpoint alerts.
What your team gains
- 01
Coverage beyond managed endpoints.
- 02
Detection of suspicious mass changes to shared data.
- 03
Storage protection managed through centralized Xcitium policies.
Before you decide
Questions, answered
What does Network Share Protection cover?
It is designed to protect shared files, network drives, file servers, and NAS storage from ransomware-related writes. Validate exact platform and protocol coverage in a pilot.
Does it address attacks from unmanaged laptops?
Xcitium names contractor, BYOD, and legacy endpoints. The scenario relies on monitoring writes at shared storage even when the device has no agent.
What happens when a suspicious write is detected?
File writes are analyzed for ransomware patterns, suspicious activity is identified, and malicious writes are blocked. Test exceptions and recovery procedures.
