Best IT MSP · Buyer's Guide
Cloud security is the set of controls, policies, and tools that protect data, applications, and infrastructure in the cloud. The key idea is the shared responsibility model: the cloud provider secures the cloud, but you are responsible for securing what you put in it. Most cloud breaches trace back to customer-side misconfiguration, not the provider, which is why expert configuration and monitoring matter.
Cloud security is the combination of policies, controls, and technologies that protect data, applications, and infrastructure running in cloud services like Microsoft 365, Azure, and AWS. As businesses move more workloads to the cloud, in a market where public cloud spending is forecast to top $723 billion in 2025[1], securing those environments has become central to protecting the whole business. This guide pairs with our cloud services and cybersecurity services overviews.
Start by understanding exactly what you are responsible for under the shared model. Then enforce least-privilege access and multi-factor authentication, encrypt data, harden and continuously check configurations, monitor for threats, and treat compliance as ongoing rather than a one-time project. Train staff, because human error and phishing remain leading causes of cloud incidents. Few small teams can do all of this alone amid a global shortfall of about 4.8 million cybersecurity professionals[3], which is why many partner with a provider.
Shortlist three providers, ask each the same questions, and compare. To start from a vetted, merit-ranked list, browse providers by city in the Best IT MSP directory.
