The Vendor Security Alliance: Why SaaS Companies Should Care

Short answer: security due diligence is the primary bottleneck in enterprise SaaS deals today. The Vendor Security Alliance standardizes the security questionnaire buyers send vendors, letting you prove your security posture once in a trusted format rather than answering a custom questionnaire for every enterprise deal.

As a SaaS attorney, I am on a lot of enterprise contracting calls, and in the last several years the security portion of those calls has taken over. The buyer’s information security manager is on nearly every deal now, asking detailed questions that the vendor’s sales and legal team are not always trained to answer. The Vendor Security Alliance exists to solve exactly that problem. Instead of every enterprise customer sending its own unique, lengthy security questionnaire, they use a standardized one. You answer it once, keep it current, and hand it to buyers on demand.

What the Vendor Security Alliance Is.

The VSA is an industry consortium that developed a standardized security questionnaire designed to benchmark vendor risk across the most important security domains: access controls, incident response, encryption, subprocessor management, business continuity, and more. In the VSA’s own description, the goal is for security experts and compliance officers to release a yearly questionnaire that companies can use to qualify vendors and ensure appropriate controls are in place. The questionnaire is public and free for vendors to complete.

The longer-term vision — a VSA-certified security score that communicates a vendor’s security posture the way a credit score communicates financial reliability — would dramatically reduce the time from security review to contract execution. Even without a universal scoring system, the standardized questionnaire format alone creates significant efficiency for both buyers and vendors.

Security Due Diligence Slows Every Enterprise Deal.

Security due diligence is the single biggest bottleneck in enterprise SaaS contracting today. The level of detail required keeps increasing: information security managers are demanding SOC 2 reports, penetration test summaries, subprocessor lists, incident response plans, and business continuity documentation. Each enterprise customer’s questionnaire is slightly different, so answering them consumes significant time from people who should be closing deals or building product. A standardized framework solves this by giving buyers a common language and vendors a consistent preparation surface.

How a SaaS Vendor Should Use the VSA Process.

If you sell to enterprise customers, the VSA questionnaire is worth completing regardless of whether the specific buyer in front of you uses it. Working through it forces you to document your security practices in the format buyers actually want. Once you have those answers and the supporting evidence — certifications, policies, architecture documentation — you have a standard security response package you can attach to any enterprise deal. Pair it with a SaaS trust site that makes your security posture publicly accessible, and you have addressed most of what a procurement team will ask before they are even on the call. For where those security commitments belong in your actual contract versus in a living policy document, see Contract or Policy?

SaaS-to-SaaS Security Ratings: The Longer View.

The long-term vision the VSA and similar frameworks are moving toward is SaaS services that can communicate their security ratings to each other automatically. That matters because nearly every SaaS company now relies on third-party integrated services — cloud storage, email delivery, analytics, payment processing — as part of its own product offering. An enterprise customer evaluating your product is implicitly evaluating all of your subprocessors as well. A trusted, standardized security rating would make that evaluation faster and more reliable for everyone. The Cloud Security Alliance has described similar network-level security transparency as the direction the industry is heading, and frameworks like the VSA are part of building toward that future.

How This Connects to Your Contracts.

Once you have completed a VSA questionnaire and have your security documentation in order, make sure your SaaS agreement references your security practices by pointing to your trust site rather than hardcoding specifics. That way, your documentation stays current without triggering a contract amendment every time you upgrade a security control. If your deals include enterprise data processing, your DPA should do the same — reference the current security standards on your trust site rather than listing specific technical measures that will go stale.

Common Questions About the Vendor Security Alliance.

Q: Is the VSA questionnaire free for vendors to complete?
A: Yes. The questionnaire is publicly available, and completing it does not require membership or a fee. The value comes from having your answers documented in a format that enterprise buyers recognize and trust.

Q: How is the VSA different from SOC 2?
A: SOC 2 is an audited certification conducted by an independent CPA firm. The VSA questionnaire is a self-reported documentation exercise. They are complementary: the VSA answers operational questions buyers have; the SOC 2 provides independent verification of controls. Enterprise buyers often want both.

Q: How often does the VSA questionnaire change?
A: The VSA updates the questionnaire periodically to reflect evolving security practices and threat landscapes. Check the VSA website for the current version and plan to review your answers annually.

If you are a SaaS company, keep up with the VSA and frameworks like it. Anything that lets you prove your security posture once, in a form buyers trust, is a tool for closing your next enterprise deal faster. I hope this helps.
