What SaaS companies should optimize for
Cloud-native evidence
Your controls live in AWS/GCP/Azure, your IdP, and your CI/CD pipeline. An auditor who reads Terraform and IAM policies natively saves weeks.
Multi-tenant scoping
Tenant isolation, encryption, and access boundaries are where SaaS audits get scoped wrong. Ask how the firm handles shared infrastructure.
Availability & confidentiality criteria
Most SaaS buyers expect more than the Security TSC — confirm the firm prices additional criteria transparently.
Annual re-audit efficiency
SOC 2 is yearly. A firm that retains context (and your GRC platform history) makes year two dramatically cheaper in time.
Frequently asked questions
Which Trust Services Criteria do SaaS companies need?
Security is mandatory. Most SaaS vendors add Availability, and many add Confidentiality — driven by what enterprise customers ask for in security reviews. Each added criterion increases scope and price, so confirm pricing per criterion.
Does SOC 2 cover my cloud provider too?
You inherit controls from AWS, GCP, or Azure via their own SOC reports (the carve-out model). Your audit covers what you build and operate on top — a SaaS-fluent auditor knows exactly where that boundary sits.
How is this list different from the main SOC 2 ranking?
Same honest signals — verification, profile completeness, reviews — but firms with confirmed GRC platform integrations rank first, because cloud-native SaaS audits run through those platforms in practice.
