You just landed a promising new customer. Everything's going well—until they send over a vendor security questionnaire asking for documents you've never heard of.
Sound familiar?
As your business grows and you start working with larger customers, you'll face more requests for compliance documentation. These aren't just bureaucratic hurdles—they're proof that you take security and data protection seriously.
The good news: most companies ask for the same core documents. Once you have these five in place, you'll be prepared for 90% of customer security reviews.
1. SOC 2 Report (Most Common)
What it is: An independent audit report verifying that your company has proper security controls in place to protect customer data.
Who asks for it: Enterprise customers, regulated companies (healthcare, finance), and any business handling sensitive customer data.
What it proves: That a certified public accounting firm has examined your security practices and confirmed you're following industry standards.
Two versions:
- Type I — Snapshot assessment of your controls at a specific point in time
- Type II — Continuous monitoring over 6-12 months (most customers prefer this)
Typical request: "Please provide your most recent SOC 2 Type II report."
How to get it: Hire a CPA firm to audit your security controls. First-time audits take 6-12 months and cost $15,000-$75,000 depending on company size.
Alternative if you don't have it yet: Offer a detailed security whitepaper, vendor security questionnaire responses, or schedule a security walkthrough call. Some customers will accept these while you're working toward SOC 2.
2. Cyber Insurance Certificate (Rising Fast)
What it is: Proof that you carry cybersecurity insurance coverage, typically including data breach response, liability, and business interruption.
Who asks for it: Customers in regulated industries, companies with strict vendor risk requirements, and businesses that have experienced breaches in their supply chain.
What it proves: That you have financial protection in place if a security incident occurs, and that an insurance underwriter has assessed and accepted your security posture.
Typical request: "Please provide a certificate of insurance showing cyber liability coverage of at least $2 million."
How to get it: Work with a commercial insurance broker who specializes in cyber policies. Annual premiums typically range from $1,500-$10,000 depending on your revenue, industry, and security controls.
Why it matters: Even if you have strong security, incidents can still happen. Cyber insurance shows customers you can respond and recover without going out of business.
3. Business Associate Agreement (BAA) for Healthcare Data
What it is: A legal contract required under HIPAA when you handle protected health information (PHI) on behalf of a healthcare provider or health plan.
Who asks for it: Hospitals, clinics, health insurance companies, healthcare SaaS platforms, or any customer subject to HIPAA regulations.
What it proves: That you understand your obligations under HIPAA and agree to safeguard patient data according to federal requirements.
Typical request: "We need a signed BAA before we can move forward. Here's our template."
How to get it: You'll typically sign the customer's BAA template. Before signing, ensure you have the technical and administrative safeguards required by HIPAA (encryption, access controls, breach notification procedures, etc.).
Red flag: If a healthcare customer doesn't ask for a BAA when you'll be handling patient data, raise the question yourself. Operating without one exposes both parties to regulatory penalties.
Not handling health data? You won't need this unless you're working in healthcare—but it's non-negotiable if you are.
4. Data Processing Agreement (DPA) for Privacy Laws
What it is: A contract that specifies how you'll handle personal data on behalf of a customer, required under privacy regulations like GDPR (Europe) and CCPA (California).
Who asks for it: European customers, California-based companies, or any customer subject to modern privacy laws.
What it proves: That you meet the legal requirements to be a "data processor" and that you'll follow rules about data retention, deletion, cross-border transfers, and individual rights.
Typical request: "Please review and sign our DPA. We need this to comply with GDPR."
How to get it: Like BAAs, customers usually provide their DPA template. Review carefully—these agreements include commitments about where data is stored, how long you retain it, and your ability to use subprocessors.
Standard clauses you'll see:
- Data transfer mechanisms (Standard Contractual Clauses for EU data)
- Data subject rights (access, deletion, portability)
- Subprocessor notification requirements
- Security incident reporting timelines
Why it matters: Operating in violation of GDPR or CCPA can result in significant fines. DPAs protect both you and your customer by clearly defining responsibilities.
5. Security Policy Documentation (Your Own Policies)
What it is: Written documentation of your internal security practices, often including:
- Information Security Policy
- Incident Response Plan
- Access Control Policy
- Data Retention and Disposal Policy
- Acceptable Use Policy
Who asks for it: Customers conducting detailed vendor risk assessments, particularly in finance, healthcare, and government sectors.
What it proves: That you have documented, consistent processes for handling security—not just ad-hoc responses.
Typical request: "Please provide your information security policy and incident response plan."
How to get it: You create these yourself (or use compliance software to generate templates). They should be:
- Specific to your company (not generic templates with blanks)
- Approved by leadership
- Reviewed and updated at least annually
- Distributed to all employees
Quick-start approach:
- 1. Start with an Information Security Policy (covers access control, encryption, monitoring, training)
- 2. Add an Incident Response Plan (who does what when something goes wrong)
- 3. Create an Acceptable Use Policy for employee device and system usage
- 4. Build the rest as customers request them
Pro tip: If you have SOC 2, your auditor will require most of these policies anyway. Getting them done early makes the audit process smoother.
Bonus: Penetration Test Results
What it is: A report from an independent security firm that attempted to hack into your systems (with your permission) to find vulnerabilities.
Who asks for it: Security-conscious customers, especially in fintech, healthtech, or when you're handling particularly sensitive data.
What it proves: That you've proactively tested your defenses and addressed critical findings.
How to get it: Hire a penetration testing firm (cost: $5,000-$25,000 depending on scope). Most companies do this annually.
Note: Not as universally required as the core five above, but increasingly common for SaaS companies.
How to Prioritize If You're Starting From Zero
If you don't have any of these documents yet, build them in this order based on what your customers are actually asking for:
Immediate priorities (answer customer requests):
- 1. Security policy documentation — you can create this yourself in 1-2 weeks
- 2. DPA template — necessary if you have EU customers or handle California residents' data
Medium-term investments (3-6 months):
- 3. Cyber insurance — shop for quotes and get coverage in place
- 4. BAA readiness — if you're in healthcare, ensure your HIPAA safeguards are documented
Long-term strategic investment (6-12 months):
- 5. SOC 2 Type II — the gold standard that satisfies most enterprise security reviews
What If You Don't Have These Yet?
Be honest with customers about your timeline and current state:
- Don't lie or dodge the question. Saying "we're in process" when you haven't started damages trust.
- Offer alternatives. "We don't have SOC 2 yet, but here's our security whitepaper and we're happy to schedule a call with our CTO to walk through our controls."
- Show your roadmap. "We've engaged [Audit Firm] and expect our Type I report by Q3."
- Know when to walk away. If a customer absolutely requires SOC 2 and you won't have it for 12 months, you may need to revisit the opportunity later.
Some prospects will work with you during the compliance journey. Others have hard requirements and won't compromise. Understanding which type of customer you're talking to saves everyone time.
The Path Forward
Compliance documentation isn't just about checking boxes—it's about building customer trust and removing friction from your sales process.
Every time you have to say "we don't have that yet" to a prospect, you're extending your sales cycle or losing the deal entirely. The companies that invest in compliance early close deals faster and compete for larger customers.
Start with what you can control: Write your security policies, get cyber insurance, and put a SOC 2 audit on your roadmap.
