Think about your CRM system as a multi-tenant apartment building. As a renter, you shouldn’t have to worry about the building’s structural integrity, power going out, or the maintenance of shared spaces and amenities. But what happens on the inside of your unit is your responsibility.
Similarly, a SaaS provider’s role is to make sure the data stored in apps like Salesforce is highly available, performant, and secure at the system level. Meanwhile, as a client, you are responsible for the data you put into it, and who you allow to access it.
