CSP can help you understand everything SharePoint and customize the design to meet your needs. Do you need cloud storage for housing all your files? An Intranet Hub for sharing company policy and news? Or, an Extranet site for collaborating with external partners? Then, SharePoint is for you.
If security is big on your agenda we can also lock-down these sites using Microsoft Conditional Access so that they become accessible only on trusted (enrolled) company devices. This is the sweet spot where mobility, security, and productivity are finally harmonized.
