What does a security audit for a SaaS product cost?
Updated: 2026-10
The cost of a security audit for a SaaS product depends on size and architecture: number of tables and roles, the type of tenant isolation, integrations and webhooks, AI features, the state of documentation and whether a re-test after fixes is wanted. A fixed scope after a short scoping is common.
A security audit for a SaaS product checks whether the foundations are right: tenant isolation at data level, authentication, handling of secrets, dependencies, backups, logging and abuse protection. It is not a penetration test but ideally precedes one, so specialists are not paid to find the obvious.
The effort depends on how much there is to check and how well the product is documented. A compact product with a clear architecture is reviewed faster than one that has grown over years.
What drives the cost
Size of the data model
Every table with customer data needs a reviewed access rule. The number of tables and relationships directly determines the review effort.
Type of tenant isolation
Isolation at database level, for example with row-level security, can be checked systematically. Isolation only in application logic requires reviewing many code paths.
Roles and permissions
More roles within a tenant, such as administrators, staff, guests and external customers, mean more combinations to check.
Integrations
Interfaces, webhooks, single sign-on and payment connections are typical attack surfaces and require their own review steps.
AI features
Features using language models add questions: prompt injection, tool permissions, data leakage and cost limits.
Documentation and re-test
Good documentation shortens the audit. A re-test after fixing the findings is a separate, usually smaller step.
How we price
- 01
Fixed scope after scoping
A short scoping clarifies architecture and scope; it yields a fixed price for review and a report with prioritised findings.
- 02
Audit with remediation support
In addition to the review, support for the team in fixing findings, for example access rules, tests and configuration.
- 03
Recurring review
For products with frequent changes, a review on a fixed cycle or before major releases.
We deliberately publish no online prices: every case differs. After a short first conversation you receive a binding fixed price or clear frame.

SaaS security & RLS audit
A SaaS security audit targets tenant isolation specifically: is row-level security watertight, does access control hold, are typical Supabase pitfalls (service role in the client, missing RLS) avoided? The output is a finding with concrete fixes.
Multi-tenant SaaS architecture
This package lays the architectural foundation for scalable SaaS: strict tenant isolation, a clean roles and permissions model, and a structure that grows with you. The result is a base on which you can build features without security and scalability becoming a later construction site.
FAQ
Is the audit a penetration test?
No. The audit checks architecture, configuration and code for fundamental weaknesses. A penetration test by specialised providers can make sense afterwards and becomes cheaper because the foundations are already right.
When is an audit worthwhile?
Before launching with sensitive data, before closing with enterprise customers, after major architectural changes and when a product has grown quickly.
Do we get concrete measures?
Yes. The report prioritises findings by severity and describes the fix for each, where possible with an automated test that prevents the problem in future.
