Engity is a cloud-based IAM or access provider. We deliver IDaaS (Identity as a Service). We do this because we believe that in most cases IDaaS is advantageous when compared to on-premise access management solutions.

For this we have our reasons and want to convince you as well.

Let's look into the differences between on-premise IAM and cloud-based IAM, along with their respective pros and cons.

What is On-Premise IAM or Access Management?

On-premise IAM refers to an Identity and Access Management system that is deployed and maintained within an organization's own infrastructure, typically within their own data centers or server rooms.

Such a setup does of course have advantages in some dimensions.

What is Cloud-based IAM (Identity as a Service - IDaaS)?

Cloud-based IAM, also referred to as Identity as a Service (IDaaS), involves using IAM capabilities provided by a third-party service provider via the cloud. The IAM infrastructure and services are hosted and maintained by the provider, accessible to organizations over the internet.

IDaaS has some obvious advantages.

On-Premise IAM or SaaS – what to choose?

Engity offers IAM only in the form of Identity as a Service as we believe that overall, the pros of a (purely) cloud-based solution by far outweigh the cons. Of course, given that there are advantages of on-premise IAM, that may not be true for every potential user, but for most of them.

Let’s look at the pros and cons listed above and assess them.

For all those reasons we at Engity believe that for most businesses and for virtually all CIAM needs cloud-based access management is the best choice.
