Very little of a typical SaaS company's compliance work is forced on it by a regulator. Most of it is pulled in by customers. A mid-market prospect sends a questionnaire, an enterprise procurement team asks for a SOC 2 report before signing, and a European customer's legal team wants a data processing agreement and a list of sub-processors. The practical question is not "which law applies" but "what evidence will the next buyer ask for, and how do we produce it once instead of forty times".
The regimes SaaS buyers ask about
SOC 2 or ISO 27001 first?
Let your pipeline decide. If most of the deals stuck in security review are with US companies, SOC 2 usually unblocks more revenue sooner, because US procurement teams are used to reading SOC 2 reports and often have a checkbox for one. If you sell into Europe or to multinationals with a central vendor standard, an ISO 27001 certificate tends to carry more weight. Our ISO 27001 vs SOC 2 comparison walks through the differences in scope, output, and audit cadence in more detail.
The overlap between the two is large: access control, change management, vendor management, incident response, logging, and risk assessment appear in both. Map controls to both frameworks from the start and the second program becomes a gap exercise. The main additions for ISO 27001 are the management system itself (scope, internal audit, management review) and a formal Statement of Applicability. The main addition for SOC 2 Type II is sustained evidence across an observation period.
What the buyer's security reviewer looks for
- A current third-party report or certificate. Reviewers check the report period or certificate expiry, the scope statement, and whether the product they are buying is actually inside that scope.
- Exceptions and complementary user entity controls. A SOC 2 report with noted exceptions is not a failure, but reviewers read them and may ask how each was fixed.
- Penetration test evidence. Usually a summary letter from an independent tester, dated within the last year, plus confirmation that high and critical findings were remediated.
- Sub-processor and data residency detail. Which cloud regions hold customer data, which vendors can access it, and how customers are told about changes.
- Identity and tenant isolation answers. SSO and MFA support, how customer data is separated, and who on your side can access production.
SaaS-specific risks and the controls that answer them
Controls reviewers expect a SaaS provider to evidence
- Production access limited to named engineers, granted through a ticket, and reviewed on a fixed schedule
- Code changes require peer review and pass automated checks before deployment, with branch protection enforced in the repository
- Secrets kept in a managed vault, never in source code
- Tenant isolation tested and included in penetration test scope
- Customer data encrypted in transit and at rest
- Backups tested by actually restoring them, with results recorded
- Offboarding that removes cloud, identity provider, code hosting, and support tool access on the same day
A sequencing plan that fits a growing SaaS company
- Write the core policy set and fix the obvious gaps. MFA everywhere, an access review, a tested backup, an incident response plan, and a vendor list. This alone answers a large share of questionnaire questions.
- Get a first attestation. A SOC 2 Type I or ISO 27001 certification gives sales something to hand over while the longer evidence period runs.
- Start the Type II observation period immediately so the first Type II report follows the Type I as closely as possible.
- Publish a trust center with the report available under NDA, policy summaries, and sub-processor list, so reviewers self-serve before emailing you.
- Add the second framework by mapping existing controls, then filling the gaps.
- Layer in privacy frameworks such as ISO/IEC 27701 when your customers start asking detailed privacy questions rather than security ones.
Pitfalls that slow SaaS teams down
- Scoping the audit to a subset of systems that does not include the product customers are buying, which reviewers notice immediately.
- Treating the audit as a one-time project, then rebuilding evidence for the next period because nobody owned the recurring controls.
- Answering questionnaires with commitments engineering never agreed to, which later become contractual obligations.
- Starting the audit before controls actually operate, producing exceptions every future reviewer will read.
Where Asurvo fits
Asurvo connects directly to the systems SaaS evidence lives in, including AWS, Azure, GCP, Okta, GitHub, GitLab, and Jira, so evidence flows in continuously and maps to controls without CSV uploads. Controls are cross-mapped, so work done for SOC 2 also counts toward ISO 27001 and GDPR. The Trust Center gives prospects a self-serve view of your security posture. Most customers are live on their first framework within a week.
