Employee survey vendor security checklist: SOC 2, ISO 27001, SSO

What should an employee survey vendor security checklist cover?

The short answer is six areas: certifications and audit evidence, data handling and encryption, access control and SSO, hosting and data residency, privacy and anonymity plus AI, and incident response and support. Cover all six before you sign, not just the one your last vendor happened to volunteer. Start from CultureMonkey's security and compliance page to see how one vendor presents this, then hold every finalist to the same bar.

01

Certifications and audit evidence

Ask for a current SOC 2 report and an ISO 27001 certificate, plus a recent penetration-test summary (an independent hacker-style test of the system's defences), so the vendor's security is independently verified rather than self-asserted.

02

Data handling and encryption

Confirm encryption in transit and at rest (so data is protected both while it travels and while it is stored), a written retention and deletion policy, a full sub-processor list, and a committed breach-notification timeframe in writing (how quickly they are required to tell you if something goes wrong). One definition first, because "processor" gets used loosely: your company is the data controller, the survey vendor you sign with is the processor, and a sub-processor is any third party the vendor brings in to handle your data on its behalf, such as its cloud host, its email delivery service, or a translation provider.

03

Access control and SSO

Require SAML/IDP-based single sign-on (the technical handshake that connects your company's existing login system to the survey tool), role-based least-privilege access, and page-level security over who sees which results.

04

Hosting and data residency

Ask where the data is hosted and with which cloud provider, and whether you can choose or confirm the specific region your survey data lives in. Ask about the second copy too: most vendors run a backup or failover database for redundancy, and it does not always sit in the same country as the primary.

05

Privacy and anonymity plus AI

Look for configurable anonymity thresholds that suppress the whole view below the minimum, scores and demographic breakdowns as well as comments, the option to roll a small team up into its parent group rather than lose the result, and clear, per-feature control over any AI analysis of survey comments.

06

Incident response and support

Expect a documented incident-response process, a named security contact or escalation path, and responsive support if you detect a suspected security issue.

25+ Security questions to send your employee survey vendor

Send this checklist to any employee survey vendor, as-is, in an RFP or a live security review. Every item is a yes/no question, not a vague area to discuss. For the broader commercial and implementation review around it, pair it with a full vendor evaluation checklist.

Should I ask a survey vendor for SOC 2 or ISO 27001?

SOC 2 and ISO 27001 are not interchangeable, and a vendor holding one does not automatically hold or need the other. ISO 27001 is an internationally recognised standard; SOC 2 is an AICPA-defined framework. Know what each actually proves before you accept either as sufficient, and match it to what your own compliance team requires when you shortlist employee engagement survey tools.

Request the SOC 2 Type II report specifically, a Type I only confirms controls were designed correctly on one day, not that they worked over time.

Neither one alone tells you everything. A vendor can hold a spotless SOC 2 Type II and still lack ISO 27001, or vice versa, ask for whichever your own compliance team requires, and don't assume one substitutes for the other.

How should a vendor handle and protect employee survey data?

Beyond certifications, four data-handling practices matter most for employee survey data specifically: encryption, retention and deletion, sub-processor disclosure, and a written breach-notification commitment. GDPR Article 33 requires notification within 72 hours of a breach — a standard worth holding any vendor to, regardless of jurisdiction.

How do I control who can see employee survey results?

Least-privilege access matters more for employee survey data than for most SaaS tools, because the whole point of the data is that most people in your company should never see individual responses.

How do I find out where a vendor stores my data?

Don't assume any vendor's hosting setup, ask directly. At minimum, require a named hosting region and cloud provider, and ask whether region choice is available for your requirement. Ask about both databases rather than one: vendors run a secondary copy for redundancy and failover, and that secondary often sits in a different location, sometimes a different country, from the primary your contract names.

1. 1Where is our data hosted, and which cloud provider do you use?
2. 2Where do the primary and the secondary (backup or failover) databases sit, and are both inside the region we agreed?
3. 3Can we choose or confirm a specific hosting region for our data?
4. 4Will you sign a Data Processing Agreement covering any international data transfers?

This is deliberately the light version. For the full requirements checklist, region-by-region rules, and vendor-question list, see data residency and GDPR for employee surveys.

What should I ask about anonymity and AI in employee surveys?

Anonymity controls and AI transparency are two separate questions buyers often blur together. Ask about both specifically, and ask about AI twice: once about what runs by default, and once about what you can switch off.

Ask any vendor for both answers in writing, per AI feature, not as a single yes or no about "AI."

How do I run a vendor security review without it dragging on?

A vendor security review is not a single step, it's a multi-stage process, and the biggest delays come from documentation requests that go back and forth instead of arriving all at once. Pulling these requirements into one place keeps them from resurfacing late; a survey vendor RFP template is the natural home for them.

• →Request the NDA and documentation together, up front, rather than one document at a time.
• →Expect a multi-stage review and budget calendar time for it, especially in regulated industries.
• →Set up allowlisting with your IT team early, so that survey invitation emails and reminders are not blocked by your company's spam filters when the survey goes live.
