Is smallstep worth the price?

Fair value

Smallstep's Enterprise-only pricing, with custom quotes, positions it as an expensive solution, especially for smaller organizations.

While the features are robust for zero-trust, the lack of transparent pricing or lower tiers makes it inaccessible for many. This model is best suited for large enterprises with complex security needs and significant budgets.
