What Is a VSAQ? Vendor Security Assessment Questionnaire Explained
VSAQ — Vendor Security Assessment Questionnaire — is a term you will encounter in enterprise sales if you sell software or cloud services to large organizations. It describes a specific type of security evaluation document, but the name is used loosely enough that vendors sometimes misidentify it or conflate it with related assessment formats. Understanding exactly what a VSAQ is, where it came from, and how to respond to one efficiently makes a measurable difference in how fast deals move through enterprise procurement.
TL;DR
• A VSAQ is a structured security questionnaire that enterprise buyers send to vendors to assess their security posture before procurement
• The term is sometimes used generically for any vendor security questionnaire, and sometimes specifically for Google’s open-source VSAQ framework
• VSAQs cover the same core domains as other security questionnaires: access control, data handling, incident response, and compliance
• Strong answers are specific, evidence-backed, and consistent across submissions
• A governed content library reduces VSAQ response time from days to hours for vendors handling high volumes
What Is a VSAQ?
A Vendor Security Assessment Questionnaire (VSAQ) is a structured document sent by a buying organization to a vendor or third-party service provider to assess the vendor’s information security practices, controls, and risk posture before or during a commercial relationship. It is one of several terms used for this category of document — alongside security questionnaire, vendor risk assessment (VRA), third-party risk questionnaire, and information security questionnaire (ISQ) — and the terminology varies by buyer organization rather than by any meaningful structural difference in the document itself.
The term VSAQ gained wider recognition when Google published an open-source Vendor Security Assessment Questionnaire framework in 2015. The Google VSAQ is a web-based tool that allows organizations to build, administer, and analyze vendor security questionnaires. Some enterprise buyers use the Google VSAQ framework directly or adapt it for their own assessments, which is why vendors occasionally encounter the acronym in a more specific technical context. For most enterprise procurement purposes, however, VSAQ simply means a vendor security questionnaire, and the response process is the same regardless of the framework used to generate it.
Why Do Enterprise Buyers Send VSAQs?
Enterprise buyers send VSAQs because they are legally, contractually, or organizationally responsible for the security of any data they share with vendors, and they need documented evidence that their vendors’ security practices meet their internal standards. A vendor who suffers a data breach can expose the buyer’s data, systems, and customers to harm — and the buyer’s board, regulators, and insurers will ask what due diligence was performed before the vendor was onboarded.
Regulatory drivers are significant and growing. Financial institutions under FFIEC, SOX, and GLBA guidance must assess third-party security. Healthcare organizations under HIPAA must vet business associates. Organizations subject to GDPR must ensure processors implement appropriate technical and organizational measures. EU enterprises under NIS2 face explicit supply chain security assessment obligations. In each case, the VSAQ is the primary mechanism for satisfying these requirements at scale.
Cyber insurance requirements have also become an important driver. Enterprise organizations must demonstrate to insurers that they actively manage third-party risk, and a documented VSAQ program — with responses, scoring, and remediation tracking — provides that evidence. For more on the full range of motivations, see why enterprise companies send security questionnaires.
What Does a VSAQ Typically Cover?
VSAQs vary in length from 30 to 300+ questions depending on the buyer’s industry, risk appetite, and the sensitivity of the data being shared. Regardless of length, they consistently cover a core set of security domains that map to the major areas of an information security management program.
Organizational security and governance covers your information security policy framework, security leadership (CISO or equivalent), security committee structures, and how security decisions are made. Buyers want evidence that security is a managed, accountable function rather than an ad hoc activity.
Access control and identity management addresses user provisioning and de-provisioning, multi-factor authentication, privileged access management, role-based access controls, and access review processes. This domain is consistently among the most heavily weighted in enterprise assessments because access failures are the leading cause of data breaches.
Data security and encryption covers data classification, encryption standards at rest and in transit, key management practices, data retention and disposal, and how the buyer’s specific data categories are handled. Buyers in regulated industries pay particular attention to encryption key ownership and data residency.
Vulnerability management and application security addresses patch management cadence, vulnerability scanning, penetration testing frequency and methodology, secure development lifecycle practices, and how security vulnerabilities are tracked and remediated.
Incident response and breach notification covers your incident response plan, breach detection capabilities, notification timeline commitments, and post-incident review process. Buyers increasingly specify contractual notification windows — 24 to 72 hours is common in GDPR and NIS2 contexts — and will ask whether your actual detection and escalation processes can support those commitments.
Business continuity and disaster recovery addresses your RTO and RPO targets, backup procedures, DR testing cadence, and your most recently validated recovery performance. Commitments that have never been tested carry limited weight with experienced evaluators.
Third-party and subprocessor management covers how you assess and manage the security of your own vendors, since your supply chain risk is the buyer’s supply chain risk by extension. This domain has expanded substantially in recent years.
How Is a VSAQ Different From Other Security Assessment Formats?
The VSAQ sits within a broader ecosystem of vendor security assessment formats. Understanding the distinctions helps vendors route incoming documents to the right internal process and prepare the most appropriate response.
A VSAQ and a security questionnaire are functionally identical — the terms describe the same document type with different names. A due diligence questionnaire (DDQ) is broader, covering financial stability, legal and regulatory compliance, and corporate governance alongside security. A CAIQ (Consensus Assessments Initiative Questionnaire) is a standardized security questionnaire published by the Cloud Security Alliance, specifically designed for cloud service providers and based on the CSA Cloud Controls Matrix. An information security questionnaire (ISQ) is another synonym for the same document type as a VSAQ.
In practice, a vendor receiving any of these documents should follow the same response process: assess the scope, route questions to the appropriate internal owners, draw from the approved content library for standard questions, escalate novel or high-sensitivity questions for review, and return the completed document by the buyer’s deadline.
What Does the Google VSAQ Framework Do?
The Google VSAQ is an open-source framework, available on GitHub, that provides tooling for building and analyzing vendor security questionnaires. It is not a questionnaire itself but a platform: organizations use it to create their own custom VSAQ, which vendors then complete through a structured web interface.
The Google VSAQ framework organizes questions into a branching structure — answers to certain questions determine which follow-up questions are asked, reducing the total number of questions a vendor must answer by skipping sections that do not apply to their environment. For example, a vendor who confirms they do not handle payment card data will skip the PCI DSS section entirely.
Vendors who receive a VSAQ built on the Google framework will complete it through a web interface rather than a downloadable spreadsheet or document. The responses are structured data rather than free text, which allows the buyer to analyze results programmatically. For vendors, the practical implication is that answers must be selected from predefined options rather than composed in narrative form — which requires knowing your control posture with enough precision to select the accurate response rather than defaulting to the most conservative option.
How Should Vendors Answer a VSAQ?
The principles for answering a VSAQ are the same as for any vendor security assessment: specificity, evidence, and consistency. Buyers who review large volumes of vendor security assessments can reliably distinguish between answers that reflect genuine security program maturity and those designed to avoid committing to anything verifiable.
Specificity means providing concrete, factual answers rather than general assurances. “We apply industry-standard encryption” communicates nothing and invites follow-up questions that a specific answer would have preempted. “Data at rest is encrypted with AES-256; data in transit uses TLS 1.2 or higher” is specific, verifiable, and closes the question. This principle applies to every domain: state the technology, the policy, the cadence, the tooling, or the metric rather than characterizing them in abstract terms.
Evidence means supporting your answers with documentation where possible. A current SOC 2 Type II audit report, an ISO 27001 certificate, or a penetration test summary from an accredited third party converts a self-declaration into an independently verified claim. Most buyers request that supporting documentation be shared under NDA as part of the VSAQ process. Vendors who have this documentation ready accelerate the review process significantly compared to those who must retrieve it on request after submission.
Consistency means that your answers to the same question are identical across every VSAQ you submit to the same buyer, and broadly consistent across all buyers. Inconsistency is the most common credibility problem in vendor security evaluations. For examples of how common questions should be framed, see security questionnaire questions and examples.
What Compliance Certifications Help Vendors Answer VSAQs?
Security certifications are the most efficient way to answer large sections of a VSAQ because they provide independent evidence that your controls meet a recognized standard. They replace self-declaration with verified attestation — which is a qualitatively different type of evidence that sophisticated buyers treat very differently.
A SOC 2 Type II report is the most broadly accepted certification in enterprise software vendor evaluations. It covers the AICPA Trust Services Criteria across security, availability, processing integrity, confidentiality, and privacy, providing independently verified evidence for the majority of access control, monitoring, data security, and incident response questions in a typical VSAQ. A current SOC 2 Type II report addresses most enterprise buyers’ baseline security evidence requirements.
ISO 27001 certification is particularly valued by European buyers and regulated industries. Its information security management system framework covers the organizational and governance dimensions of VSAQ questions that SOC 2 addresses less directly. Vendors selling to EU enterprises or regulated global enterprises benefit from holding both.
Sector-specific certifications — PCI DSS compliance for payment data, HIPAA attestation for healthcare, FedRAMP for US federal government — address the specialized compliance sections of VSAQs from buyers in those regulated industries. For cloud vendors, a completed CAIQ published to the CSA STAR registry provides a standardized, publicly verifiable security disclosure that reduces the per-buyer VSAQ effort for cloud-specific questions.
How Do VSAQs Fit Into the RFP and Procurement Lifecycle?
VSAQs appear at multiple points in the enterprise procurement lifecycle, not just during initial vendor selection. Understanding where they fit helps vendors maintain the right state of readiness throughout a commercial relationship.
During initial RFP and vendor evaluation, a VSAQ may be included as a mandatory component of the solicitation response, evaluated alongside technical capability and commercial terms. In these cases, a weak VSAQ response can disqualify an otherwise competitive vendor before the commercial evaluation reaches its conclusion.
Post-selection, a VSAQ is often triggered by the award of a preferred vendor status — either after a formal RFP or as part of a direct vendor onboarding process. At this stage, the VSAQ functions as a final due diligence gate before contract execution. Deals that appear won can stall or fail at this stage when vendors cannot complete the security review promptly or when their answers reveal gaps the buyer’s risk team cannot accept.
Annually, existing vendors are often required to complete a refreshed VSAQ as part of ongoing third-party risk management. Buyers are asking: has anything changed in your security posture since we last assessed you? Maintaining a current, accurate response library makes annual reassessments significantly less burdensome than treating each one as a fresh exercise.
How Should Vendors Build a VSAQ Response Process?
A structured VSAQ response process produces better answers faster and with less organizational disruption than ad hoc responses assembled under deadline pressure. The foundation is a governed content library; the process layer above it defines how incoming VSAQs are triaged, routed, completed, and reviewed.
The content library is a centralized repository of pre-approved answers to common VSAQ questions, organized by security domain, maintained by defined owners, and reviewed on a regular cadence. This library is the single source of truth for all vendor security assessment responses. When a VSAQ arrives, the first step is mapping its questions to library answers — for most standard VSAQs, 60–80% of questions will be answered directly from the library, requiring review rather than drafting.
The triage layer assesses the VSAQ’s scope, identifies questions that require subject matter expert input beyond the content library, estimates the completion timeline, and routes appropriately. Questions about specific infrastructure configurations, novel compliance requirements, or high-sensitivity data handling should be routed to the security team for review before submission. Standard questions — encryption standards, MFA policies, incident response timelines — should flow from the library without escalation.
The governance layer defines who owns the content library, how frequently answers are reviewed for accuracy, and what triggers an update. A library that is not current is worse than no library, because it produces systematically inaccurate answers at scale. Build content review into your security team’s annual calendar and assign ownership of each domain to a named individual.
How Can Automation Reduce VSAQ Response Time and Cost?
For vendors responding to high volumes of VSAQs, the time and cost of manual response is substantial. A single detailed VSAQ from a regulated enterprise buyer can require 20–40 hours of combined security, legal, and engineering time if handled without a structured process and content library. Across a portfolio of 30–50 annual assessments, this represents hundreds of hours of high-cost team time that could be directed elsewhere.
Automation reduces this cost primarily by eliminating the first-draft writing effort for questions that appear repeatedly across assessments. When approved answers are stored in a searchable library and matched automatically to incoming questions, the human effort shifts from drafting to reviewing and approving. For standard VSAQ questions, this review-rather-than-write workflow is typically two to three times faster than starting from scratch.
The consistency benefit is equally important. When every answer is drawn from the same governed source, the risk of contradictory responses across submissions to the same buyer disappears. A vendor whose security architect answers a question one way in a VSAQ and a different way in an RFP compliance section — because neither had access to the other’s response — creates a credibility problem that is difficult to repair in a competitive evaluation.
For teams managing high volumes of VSAQs, security questionnaires, and RFP compliance sections, Steerlab.ai automates the generation of responses from your approved content library — ensuring that every VSAQ your team submits draws from the same governed source, is reviewed rather than drafted from scratch, and reaches the buyer faster than manually assembled responses.
Frequently Asked Questions
What does VSAQ stand for?
VSAQ stands for Vendor Security Assessment Questionnaire. It is a structured document sent by a buying organization to a vendor to assess the vendor’s information security controls, policies, and risk posture. The term is used interchangeably with security questionnaire, vendor risk assessment, and information security questionnaire. It also refers specifically to an open-source questionnaire framework developed and published by Google, which some enterprise buyers use to build and administer their vendor security assessments.
What is the Google VSAQ?
The Google VSAQ is an open-source Vendor Security Assessment Questionnaire framework that Google published in 2015 and made available on GitHub. It provides tooling for organizations to build, administer, and analyze vendor security questionnaires through a web-based interface with branching logic — answers to certain questions determine which follow-up questions are displayed. Some enterprise buyers use the Google VSAQ framework directly or adapt it for their own assessments. Vendors completing a Google VSAQ-based assessment will do so through a structured web interface rather than a spreadsheet or document.
How is a VSAQ different from a security questionnaire?
In most enterprise procurement contexts, they are the same thing. VSAQ (Vendor Security Assessment Questionnaire) and security questionnaire both describe a structured document sent by a buyer to a vendor to assess security posture. The terminology varies by organization rather than by any meaningful structural or content difference. The response process, the question domains covered, and the evidence requirements are identical regardless of which term the buyer uses.
How long does it take to complete a VSAQ?
Completion time depends on the questionnaire’s length and complexity, and on how prepared the vendor is. A 50-question VSAQ from a mid-market buyer can take two to four hours for a vendor with a current content library. A 200-question VSAQ from a regulated enterprise requiring input from security, legal, and engineering teams can take one to three weeks without a structured process. Vendors with a governed content library and defined routing process consistently complete VSAQs in 30–50% of the time required by those relying on ad hoc responses.
What certifications help most when completing a VSAQ?
SOC 2 Type II is the most broadly accepted certification for enterprise vendor security evaluations, covering the security, availability, processing integrity, confidentiality, and privacy domains that constitute the majority of VSAQ questions. ISO 27001 certification is particularly valuable for European buyers and regulated industries. PCI DSS, HIPAA attestation, and FedRAMP address specialized sections of VSAQs from regulated industry buyers. A completed CAIQ on the CSA STAR registry provides cloud-specific security evidence that reduces per-buyer questionnaire effort for vendors in the cloud services category.
Is there software that automates VSAQ responses?
Yes. Response automation platforms maintain a governed library of approved answers to common VSAQ questions that can be matched to incoming questionnaires and deployed rapidly. Steerlab.ai automates the generation of VSAQ and security questionnaire responses from your approved content library — matching incoming questions to governed answers, flagging novel questions for SME review, and ensuring consistency across every submission your team produces. For vendors responding to multiple enterprise buyers simultaneously, this automation significantly reduces response time and eliminates the consistency problems that arise from manual, per-questionnaire drafting.
Can you decline to answer questions in a VSAQ?
Yes, but it has consequences. Declining specific questions — typically citing confidentiality or operational security concerns around disclosing infrastructure specifics — is sometimes appropriate. However, a pattern of declined questions signals something to hide and reduces credibility at a sensitive stage of the commercial relationship. The better approach is to offer an alternative: answer at a summary level without exposing operational specifics, offer to share detailed information under NDA, or reference a third-party audit report that covers the relevant control. This maintains transparency while protecting genuinely sensitive technical information.
What happens after a vendor completes a VSAQ?
After submission, the buyer’s security or procurement team reviews the responses and typically takes one of three actions: approves the vendor for onboarding or contract execution, identifies gaps requiring remediation before proceeding, or escalates specific findings to a risk committee for a formal risk acceptance decision. Hard failures — absence of MFA, no incident response plan, unencrypted data storage — are typically disqualifying. Soft gaps — an annual penetration test rather than semi-annual, a policy that exists but is not yet formally documented — often trigger a remediation request rather than outright disqualification. Understanding which questions are likely to be hard disqualifiers versus negotiable gaps helps vendors prioritize their security investments before entering major enterprise evaluations.
