Choosing a managed security service: questions to ask

Managed security is not a single standard package. Buyers should understand what data is monitored, who reviews alerts, what actions are permitted, how they are contacted and which responsibilities remain with their own team.

Key takeaways

  • •Ask exactly what is included and monitored.
  • •Clarify service hours and response arrangements.
  • •Agree escalation contacts and actions in advance.
  • •Check integrations, onboarding and exit requirements.

Define the service boundary

List products, telemetry, users, devices and cloud environments included. Understand exclusions, customer dependencies and how scope changes are handled.

Understand monitoring and escalation

Ask what the stated coverage hours mean, how alerts are triaged, which events trigger contact and how contact attempts are documented. Confirm response targets in the written service terms.

Agree response permissions

Containment can affect business operations. Clarify actions that can be taken without approval, actions requiring approval, and how emergencies are handled.

Plan onboarding and reporting

Confirm prerequisites, access, integrations, expected handover, reporting format and review schedule. Check what the customer must maintain to keep coverage effective.

Compare proposals on outcomes and accountability

Compare service scope, responsibilities, evidence, costs and contractual commitments rather than relying only on labels such as MDR or 24/7.
