In short: this is the starting point for everything Cyber Snowden has published on securing AWS, Azure, Google Cloud and Kubernetes. The guides are grouped by task, from understanding the risks to choosing tools and running a multicloud estate.
Cloud security differs from data centre security in one important way: the provider secures the platform, but you remain responsible for how it is configured and who can reach it. The articles below focus on that customer side of the shared responsibility model.
Start here: read the top cloud storage misconfiguration risks to see what goes wrong most often, then our CSPM guide to see how teams find and fix those issues at scale.

Frequently asked questions
Who is responsible for security in the cloud?
Both parties, for different things. The provider secures the underlying infrastructure. The customer is responsible for configuration, identities, access and data. Most cloud incidents trace back to the customer side of that split.
What is the biggest cloud security risk?
Misconfiguration. Publicly exposed storage, over-permissive roles and unrotated keys cause far more incidents than flaws in the cloud platforms themselves.
Where should a small team start?
Turn on the free native security tools from your provider, enforce multifactor authentication for every administrator, and review storage and network exposure. Add specialist tools once that baseline is in place.
