Step-by-Step Vendor Security Assessment Guide for Non-Technical Business Owners
Table of Contents
Vendor partnerships are the backbone of many small businesses today, but they also introduce significant risks when it comes to safeguarding sensitive company and customer data. Fortunately, you don’t need to be an IT expert to assess vendor security. This practical, step-by-step guide—packed with tables, checklists, and plain-language templates—walks non-technical business owners through the essentials of keeping your company safe while working with third parties.
Why Vendor Security Assessment Matters
Cybersecurity statistics show that up to 60% of small business data breaches originate with a third-party vendor. With trends showing more SMBs using cloud services, payment processors, and remote support, your vendor’s security can become your risk unless you ask the right questions and make clear-eyed decisions.

Vendor Security Assessment—Myths and Realities
| Myth | Fact |
|---|---|
| Only IT pros can assess vendors | Any business leader can assess security with structured guides and simplified questions |
| Big-name vendors are always safe | Even large, well-known vendors have suffered breaches. Always check for recent incidents and current certifications |
| Once a vendor is approved, you’re done | Regular reassessment is critical—tools and policies change faster than contracts |
Story: A café lost 800+ customer emails after its newsletter vendor got hacked. A basic checklist could have revealed their lack of encryption.
Understanding Vendor Risks
Vendors often require some level of access to your IT systems or data. Common risks they introduce:
- Unauthorized or excessive data access
- Poor password/security controls
- Unnoticed security incidents or data leaks
- Regulatory compliance failures (GDPR, PCI-DSS, etc.)
- Service interruption due to vendor breach
Foundation: Know Your Vendors & What They Access
Start by creating a simple vendor inventory table:
| Vendor | Product/Service | What Data is Shared? | Access Type | Contact Person |
|---|---|---|---|---|
| EmailBlastPro | Email Marketing | Customer emails, names | Cloud API | jessica@emailblastpro.com |
| Bookify | Online Bookings | Client info, payment data | Dashboard portal | support@bookify.io |
Step-by-Step Vendor Security Assessment Guide
Step 1. Identify & Classify Your Vendors
Classify vendors by how critical their access is. Use this sample:
| Vendor | Risk Level | Why? |
|---|---|---|
| Payroll Processor | High | Has employee SSNs, salary data |
| Coffee Supplier | Low | No access to IT or client info |
Step 2. Gather Essential Vendor Information (Non-Technical Cheatsheet)
- SOC 2 or ISO 27001 certifications?
- Cyber liability insurance certificate?
- Privacy and security policy (recent version)?
- List of subcontractors with data access?
- Record of past security incidents/breaches?
Email Request Example:
“Dear Vendor,
As part of our regular security process, could you provide your latest SOC 2 report and a copy of your incident response plan? This will help us ensure compliance for both our companies. Thank you!”
Step 3. Ask the Right Questions—Plain English Questionnaire
| Question | Tip for Good Answers | Red Flag |
|---|---|---|
| How do you protect my data? | Describes encryption and role-based access | Vague or ignores the question |
| What happens if there’s a breach? | Has a documented incident response plan, alert process | Unclear, says “never happens” |
| Who else can see my data? | Provides subcontractor list, limits | “We don’t disclose” |
| How often do you run security tests? | Yearly or ongoing, with results shared | No info, never tested |
Step 4. Assess Vendor Controls & Processes Without Tech Jargon
- MFA (Multi-Factor Authentication): Is it required for all user logins?
- Encryption: Do they encrypt your data at rest and in transit?
- Backups: Do they keep regular backups and test restores?
- Employee training: How often is staff security awareness updated?
Each of these steps protects your data even if vendor systems are targeted by hackers.
Step 5. Review & Score the Vendor (With a Simple Template)
| Control | Score (0-2) | Notes |
|---|---|---|
| Certifications | 2 | Has up-to-date SOC 2 |
| Incident Response | 1 | Policy in place, not recently tested |
| Access Controls | 2 | Strong passwords, MFA required |
| Data Handling | 1 | Encrypts in transit, not at rest |
Tip: Score of 7+ (out of 8) is low risk. 5–6 = medium. 0–4 = high risk/review.
Step 6. Make Your Decision and Get it in Writing
Based on your assessment, you can:
- Approve the vendor as safe (document your decision)
- Approve with required changes (“Enable MFA within 30 days”)
- Reject, if risks are too high or vendor is uncooperative
Always add contract clauses for: breach notification, data access limits, right to audit, mandatory ongoing security updates, and exit/termination provisions.

Best Practices and Pitfalls to Avoid
- Document everything and keep records in a single place
- Follow up with vendors annually—don’t assume policies are unchanged
- Share your assessment findings with all business leaders/decision makers
- Never overlook low-cost or free automated tools as a first step
| Common Mistake | Solution |
|---|---|
| Relying solely on vendor reputation | Always review current controls and certifications independently |
| Not updating your assessment regularly | Set reminders for periodic review and tool re-checks |
| No contract clauses for breach notification | Add a clause requiring vendors to notify you of incidents ASAP |
Ongoing Vendor Monitoring
- Set up periodic reviews (quarterly or annually) using automated tools
- Subscribe to alerts if vendors have security incidents (many tools provide this feature)
- Update contact info and review incident response at least annually
Simple Incident Response Flowchart:
- Vendor alerts you to an incident
- Assess incident type and data affected
- Review if contract obligations were met
- Decide next steps: notify clients, enhance security, replace vendor if needed

Case Study: Real-World SMB Lessons
Before: A local retailer used a POS vendor without checking their policies. After a breach, cardholder details were leaked.
After: The same retailer started using a scoring template, switched to a more secure vendor, required annual checks, and avoided the next wave of attacks affecting competitors.
