Agencies should require SOC 2 compliance from SaaS vendors that handle client data, credentials, or anything covered by client contracts—but not for every low-risk tool. SOC 2 is a strong signal of mature security controls, yet it's one input among several. Match the requirement to the data sensitivity and your own contractual obligations rather than applying it blanket-style.

What SOC 2 Actually Covers

SOC 2 (System and Organization Controls 2) is an audit framework from the AICPA that evaluates how a service provider manages data based on five Trust Services Criteria: security, availability, processing integrity, confidentiality, and privacy. Security is mandatory; the other four are optional depending on what the vendor opts into.

There are two report types, and the difference matters:

  • Type I — Confirms controls are designed correctly at a single point in time. Cheaper, faster, weaker evidence.
  • Type II — Confirms controls operated effectively over a period (usually 3–12 months). This is the one most agencies should ask for.

A Type I report tells you a vendor drew a nice security diagram. A Type II tells you they actually followed it for months. Most teams get this wrong and accept a Type I as if it carries the same weight.

When Agencies Should Require It

The answer depends on what the tool touches. Tier your vendors by data risk:

Require SOC 2 Type II

  • CRMs holding client contact and pipeline data
  • Proposal and RFP platforms storing client commercials
  • Analytics tools ingesting first-party customer data
  • Anything storing PII, financial data, or login credentials
  • Tools where your own client contracts mandate downstream compliance

If you're running competitive enterprise deals through a platform—say comparing Outreach vs Salesloft for a client's outbound motion—that vendor is sitting on sensitive prospect data and should hold a current Type II report.

SOC 2 is nice-to-have, not mandatory

  • Internal-only design tools with no client data
  • Public content schedulers
  • Standalone calculators or formatting utilities

Acceptable alternatives

SOC 2 isn't the only credible standard. ISO 27001, HIPAA attestations, or a completed CAIQ questionnaire can satisfy the same risk concerns—especially for vendors based outside North America, where ISO 27001 is more common than SOC 2.

How to Evaluate a Vendor's SOC 2 Report

Getting a report isn't the finish line. Read it.

  1. Check the report date. SOC 2 reports cover a defined audit window. A report ending more than 12 months ago is stale—ask for a bridge letter or the current period.
  2. Read the scope section. Confirm the audited system is the product you're buying, not a parent company's unrelated infrastructure.
  3. Review exceptions. The auditor lists control failures here. A clean report with zero exceptions is rare; what matters is whether exceptions were remediated.
  4. Confirm subservice organizations. If the vendor relies on AWS or another sub-processor, the report should note carve-outs and complementary controls.

For procurement-heavy migrations—like moving thousands of records during a Qvidian to Responsive migration—the SOC 2 review should happen before any data leaves your existing system, not after.

The Real Cost of Requiring SOC 2

Blanket SOC 2 requirements slow procurement and exclude strong early-stage vendors who haven't completed an audit yet (a Type II takes 6–12 months and costs $30k–$100k+ to obtain). That tradeoff is worth it for client-data tools and counterproductive for low-risk utilities.

A pragmatic policy:

  • High-risk tools: SOC 2 Type II or ISO 27001 required, no exceptions
  • Medium-risk: Type II preferred; Type I plus a security questionnaire acceptable
  • Low-risk: Standard security questionnaire only

What to Ask Beyond SOC 2

SOC 2 measures process maturity, not whether a tool fits your workflow. Pair the compliance check with practical due diligence:

  • Data residency and where backups are stored
  • Breach notification timelines in the contract
  • Sub-processor list and right to audit
  • Data deletion guarantees on contract termination

When you're standardizing your sales stack—comparing options like HubSpot vs Salesforce for client CRM work—build the security review into your evaluation rubric rather than bolting it on at contract signing.

Key Takeaways

  • Require SOC 2 Type II (not Type I) for any SaaS vendor handling client data, credentials, or PII.
  • Don't apply SOC 2 as a blanket requirement—tier vendors by data sensitivity and your own contractual obligations.
  • Accept ISO 27001 or equivalent as a credible alternative, especially for non-US vendors.
  • Always read the actual report: check the date, scope, exceptions, and sub-processor carve-outs.
  • SOC 2 is necessary but not sufficient; pair it with questions on data residency, breach notification, and deletion guarantees.
