Small Business TPRM Series: Part 5: What to Ask Vendors: Practical Security Questions
Introduction
When you bring a new vendor into your business (whether it’s a cloud platform, MSP, payroll provider, or marketing tool), you’re trusting them with your operations, your data, and your reputation. But most small businesses don’t know what to ask vendors before signing a contract or granting access.
The good news: you don’t need to be a cybersecurity expert to ask smart, meaningful questions. A short, practical set of questions can reveal a lot about a vendor’s security posture and help you avoid unnecessary risk.
Why This Topic Matters
Many SMBs assume that well‑known vendors are automatically secure. But even reputable companies can have weak controls, misconfigurations, or poor incident response practices. Attackers know this — and they increasingly target vendors because compromising one provider can give them access to dozens or hundreds of clients.
Small businesses often overlook:
- Whether a vendor uses MFA
- How a vendor protects customer data
- Whether the vendor has been breached before
- How quickly the vendor will notify you of an incident
- Whether the vendor outsources work to other companies
Asking the right questions helps you identify red flags early and choose vendors who take security seriously.

- How this fits into your overall TPRM program
Plain Language Explanation
Vendor security questions help you understand how a vendor protects your data and systems. You don’t need a long, technical questionnaire — just a focused set of questions that reveal whether the vendor follows basic security hygiene.
The goal isn’t to interrogate vendors. It’s to:
- Set expectations
- Identify risks
- Compare vendors fairly
- Document your due diligence
- Make informed decisions
A vendor who can’t answer basic questions — or refuses to — is a vendor you should think twice about.
Practical Steps for Small Businesses
1. Start With These 10 Essential Questions
These questions work for almost any vendor:
- Do you require multi‑factor authentication (MFA) for your staff and customers?
- How do you protect customer data (encryption, access controls, etc.)?
- Do you conduct regular security testing (internal or external)?
- Do you have a documented incident response plan?
- How quickly will you notify us if you experience a breach?
- Do you use subcontractors or sub‑processors? If so, how do you vet them?
- Do you have cyber insurance?
- Do you provide security documentation (SOC 2, ISO 27001, security summary)?
- How do you manage employee access to customer data?
- What happens to our data if we end the relationship?
These questions are simple, but they reveal a lot.
2. Tailor Questions Based on Vendor Risk Tier
Use your vendor classification from Article 4:
High‑Risk Vendors
Ask all 10 essential questions plus:
- Do you encrypt data at rest and in transit?
- Do you have a business continuity plan?
- Do you undergo annual penetration testing?
- How do you secure remote access?
- Can we review your SOC 2 or ISO 27001 documentation?
Medium‑Risk Vendors
Ask the 10 essential questions and request a security summary.
Low‑Risk Vendors
A simple confirmation of data handling and access is usually enough.
3. Know What Good Answers Look Like
You don’t need to be a security expert — look for:
- Clear, confident explanations
- Written policies or documentation
- Evidence of regular testing or audits
- Transparency about subcontractors
- Defined breach notification timelines
Vague answers are a red flag.
4. Watch for Common Red Flags
Be cautious if a vendor:
- Refuses to answer basic questions
- Claims “we don’t need MFA”
- Has no incident response plan
- Won’t disclose subcontractors
- Has no documentation of security practices
- Says “we’ve never been breached” (often untrue or uninformed)
These are signs of weak security hygiene.
5. Document the Responses
Keep a simple record:
- Vendor name
- Date of review
- Answers provided
- Any concerns or follow‑ups
- Final risk tier
This helps with audits, insurance, and future reviews.
Tools, Tips, and Real‑World Examples
Common SMB Mistakes
- Asking no questions at all
- Accepting vague or verbal answers
- Not documenting vendor responses
- Not revisiting questions annually
- Assuming MSPs are automatically secure
Simple Tools SMBs Can Use
- A one‑page questionnaire
- A shared spreadsheet for tracking responses
- Google Alerts for vendor breach news
- A contract addendum with security expectations
Real‑World Scenario
A small nonprofit hired a web developer who stored donor data on an unsecured personal laptop. When the laptop was stolen, donor information was exposed. The nonprofit had never asked the developer how data was stored or protected.
A single question — “How do you secure customer data?” — could have prevented the incident.
Summary
Asking vendors practical security questions is a critical part of Third‑Party Risk Management. A simple, non‑technical questionnaire helps you understand how vendors protect your data, identify red flags, and make informed decisions. You don’t need complexity — just consistency.
