Cyber Security Services
Cyber security services are outside help that protects an organization's or person's systems, accounts, and data, from round-the-clock monitoring to one-time assessments, compliance preparation, and staff training. This independent guide explains what each service delivers, when it fits, and how to compare what providers actually promise.

MSSP and MDR, briefly
Neither term has one legal definition. Providers use them differently, so ask what is included.
- MSSP (managed security service provider)
- Usually a firm that runs or monitors security tools for customers under an agreement, often across many technologies.
- MDR (managed detection and response)
- Usually a service focused on finding threats and acting on them, often with the provider's own tools. Response authority varies, so check it in writing.
Reader questions
What do cyber security services include?
Most fall into monitoring, protection, assessment, remediation, compliance preparation, consulting, and training. Few providers do all of them equally well, so match the service to the problem.
Which cyber security services do companies need first?
It depends on what could stop your business. The federal CISA guidance for small businesses starts with leadership ownership and basic account protection such as multifactor authentication, before any large purchase.
Are there free government cyber security services?
Some. CISA publishes a list of no-cost cybersecurity services and tools. Check each entry, because eligibility varies.
Does this guide recommend a provider?
No. Security Briefing is an independent news magazine, and these guides explain how to evaluate services rather than rank or recommend specific providers.
