TL;DR: Administrators can turn device commands into alerts for specific conditions such as service crashes, log entries, process presence, registry changes, and file system events, according to JumpCloud. The governance question is not whether monitoring can be customised, but whether alert logic is tied to clear control outcomes instead of noisy exceptions.
NHIMG editorial — based on content published by JumpCloud: custom script-based alerting for managed devices
Questions worth separating out
Q: How should teams design custom alerts for managed endpoints?
A: Start with a single condition that matters to the business or security programme, then build the script so it returns a clear pass or fail result.
Q: When do custom script alerts add more value than standard monitoring templates?
A: They add the most value when the organisation needs to verify a local assumption that default templates cannot see, such as a specific process, registry setting, log event, or file state.
Q: What do security teams get wrong about script-based alerting?
A: They often treat it like a generic monitoring feature instead of a control verification mechanism.
Practitioner guidance
- Define each alert around one control outcome Tie every custom command to a single security or operational state, such as a required service running, a log entry appearing, or a security setting remaining enabled.
- Run scripts in the intended execution context Validate commands as the same account and OS context they will use in production, such as LocalSystem on Windows or root on Linux, so permissions and environment assumptions do not distort results.
- Map alerts to named governance controls Document which policy, hardening requirement, or compliance check each alert supports, then review whether the command still reflects that control after every platform or application change.

JumpCloud's full how-to covers the operational detail this post intentionally leaves for the source:
- Step-by-step command creation and rule setup in the Admin Portal for device groups and operating systems.
- Examples of PowerShell and Bash checks for Windows Event Log service crashes and macOS Gatekeeper status.
- Guidance on choosing run-as context, exit-code logic, and alert priority for production deployment.
- Practical examples of when a custom command should trigger on a non-zero exit code rather than a template threshold.

Custom script alerting is best understood as a local verification layer, not a monitoring strategy by itself. The article shows that teams often need device-specific checks to validate process state, service health, file presence, or log evidence. That is valuable because default alert templates cannot cover every operating assumption. But the broader governance lesson is that bespoke alerts only work when the condition being checked maps cleanly to a control outcome. Practitioners should treat each script as an expression of a single control objective, not as a generic monitoring escape hatch.
A few things that frame the scale:
- 70% of organisations grant AI systems more access than they would give a human employee performing the exact same job, according to The 2026 Infrastructure Identity Survey.
- 69% of security leaders agree identity management must fundamentally shift to address agentic AI systems.
A question worth separating out:
Q: How should organisations govern custom alerts once they are in place?
A: Treat them like operational controls with ownership, versioning, testing, and periodic review. Custom alerts should be retired when the underlying system changes, and they should be tied to a documented response path so the team can act quickly when the condition appears.
