Your business depends on tools and partners you do not control: your payroll provider, your email platform, your marketing apps, your bookkeeper. Each one can become your breach if their security fails. This is third-party risk, and you do not need an enterprise program to manage it. Here is a five-step review a small business can run in an afternoon.

1. List who can touch your data

Write down every outside service and partner that stores, processes, or can access your business or customer data. Include the obvious platforms and the easy-to-forget ones: that marketing tool with a copy of your customer list, the contractor with a login, the app someone signed up for last year.

2. Rank them by what they could expose

You cannot review everyone equally, so do not try. Sort the list by impact: which vendors hold sensitive data, money, or deep access to your systems? Those are your high-priority few. Spend your attention there.

3. Ask the high-priority vendors three questions

• Do you support multi-factor authentication on our accounts, and is it on?
• How is our data protected, and do you hold a recognized security certification (for example SOC 2 or ISO 27001)?
• How and how quickly would you notify us if you had a breach?

The answers, and how willing they are to give them, tell you a lot.

4. Right-size their access

Give every vendor the least access they need to do the job, and no more. Turn on MFA for the accounts they use, use separate logins instead of shared ones, and remove access the moment a contract ends. A marketing tool does not need standing access to your full customer database forever.

5. Review on a schedule

Vendors change, and so does your stack. Put a recurring reminder, once or twice a year, to revisit the list, drop tools you no longer use, and recheck the high-priority few. Twenty minutes on the calendar prevents the forgotten-vendor breach.
