TL;DR: MSSPs that promise to support whatever stack a customer already runs still face the same scaling problem: analysts, detections, and playbooks fragment across EDR, SIEM, and logging variations, according to LimaCharlie. Agentic operators and a shared telemetry layer reduce manual effort, but governance over scoped permissions and auditability remains the deciding control.
NHIMG editorial — based on content published by LimaCharlie: MSSPs: Support any customer stack without losing your sanity
Questions worth separating out
A: MSSPs need a normalised telemetry layer that sits above customer tools and standardises investigations, hunts, and detections.
Q: Why does stack diversity make managed security harder to scale?
A: Stack diversity fragments tooling, rule formats, and response workflows, so every tenant behaves like a custom implementation.
Q: What do teams get wrong about agentic SOC automation?
A: They often assume automation and autonomy are the same thing.
Practitioner guidance
- Define operator scopes for AI-run SecOps tasks Separate triage, hunting, containment, and detection authoring into distinct permission sets so an operator can only perform the actions required for its role.
- Normalise telemetry before adding more tenants Create a common query and investigation layer over customer data so analysts do not have to relearn interfaces for each environment.
- Measure how much work still depends on bespoke playbooks Track the percentage of investigations, detections, and containment actions that still require manual tenant-specific branching.

Stack diversity is becoming a SecOps governance debt, not just an integration nuisance. The operational cost of supporting many customer toolchains is that every workflow becomes bespoke, and bespoke workflows do not scale safely. For MSSPs, that means the problem is less about which EDR or SIEM a customer uses and more about whether the provider can preserve consistent controls across heterogeneous environments. Practitioners should treat stack diversity as a control-design issue, not a sales objection.
A question worth separating out:
Q: Who is accountable when an AI operator takes containment action in a customer environment?
A: Accountability should sit with the MSSP function that defines the operator’s scope, the customer relationship that authorises it, and the governance process that approves the action path. If those roles are unclear, the organisation has built automation faster than it built control ownership.
