What is SOC 2 Compliance?

The five Trust Services Criteria

SOC 2 is structured around five Trust Services Criteria (TSC). Security is mandatory — every SOC 2 includes it. The other four are optional and only included if your contracts demand them. Availability — uptime commitments and incident management. Confidentiality — handling of customer-classified data. Processing Integrity — accuracy and completeness of processing, relevant when your software does work customers rely on financially. Privacy — handling of personal information per declared notices.

Most early-stage SaaS just gets the security TSC. Larger organizations add availability and confidentiality. Healthcare and fintech sometimes go further.

Type 1 vs Type 2 — the only distinction that matters

SOC 2 Type 1 says your controls existed and were designed appropriately on a single date. It is a snapshot. Procurement teams know it is a starter credential. Type 2 says your controls have operated effectively over a period — typically 6 to 12 months — and includes evidence sampled from that whole window. Type 2 is what enterprise buyers want. Many will accept Type 1 as a placeholder while you work toward Type 2, but they will circle back.

When SOC 2 starts to actually matter

Three triggers usually bring it forward in the roadmap. An enterprise prospect asks for the report during procurement — the most common path, and the one where deferring further can cost six-figure deals. A renewal customer adds it to their annual vendor review. Or an investor's due diligence team flags it as table stakes for the next round. None of those triggers wait politely. If any of them are within the next year, starting Type 1 readiness now is cheaper than the scramble of starting after the ask lands.

The hidden cost

The auditor's bill is the smallest line item. The real cost is the controls themselves: a vulnerability management program, an annual penetration test, formal access reviews, change management, an incident response plan, vendor risk reviews, and tooling to keep evidence flowing. Compliance platforms (Vanta, Drata, Secureframe) help, but they do not do the work for you — they automate evidence collection from systems where the controls already exist.

At QUANT LAB

We help founders prepare the technical side of a SOC 2 audit: building the access control, audit logging, encryption, and backup posture the audit will sample. Annual third-party penetration testing is a SOC 2 expectation, and our pentest engagements are scoped to satisfy that requirement. For the platform side, our SaaS platform development engagements include a "SOC 2 ready" track that delivers the controls baked into the application from day one — which is roughly ten times cheaper than retrofitting them later.

SOC 2 vs ISO 27001 vs others

SOC 2 dominates US B2B SaaS procurement. ISO 27001 dominates in Europe and is increasingly common at global enterprises. The two are not interchangeable but cover overlapping ground, and many organizations get both because different customers ask for different reports. PCI-DSS, HIPAA, and FedRAMP are domain-specific overlays on top. The shortcut for early stage: start with SOC 2 Type 1, then layer in ISO 27001 only when European deals demand it.
