Vendor Risk Basics for Growing Companies
Every vendor with access to your data or systems is an extension of your own security posture — including the ones nobody thought to evaluate before signing up.
The business problem
Growing companies accumulate vendors fast — a payroll processor, a CRM, a handful of SaaS tools a team signed up for on a credit card — and rarely evaluate any of them for security risk before granting access to customer data or internal systems. A breach at any one of those vendors can become the growing company’s breach, even though the growing company never touched the vulnerable system.
What right-sized vendor risk management looks like
You don’t need a formal third-party risk program to start. You need a short list of your most important vendors — the ones with access to sensitive data or critical systems — and a basic evaluation for each: do they have a SOC 2 or similar attestation, what data can they access, and what happens to your data if they’re breached. Lower-risk vendors (a scheduling tool with no sensitive data) don’t need the same scrutiny as a payroll processor.
Why it matters
Supply chain and vendor-originated breaches are a growing share of incidents precisely because attackers know smaller vendors are often less scrutinized than the companies that rely on them. Your own controls can be excellent and still be undermined by a vendor’s weak ones, if you never asked the question.
“You inherit your vendors’ security posture the moment you give them access — whether or not you ever asked what that posture actually is.”
Signs vendor risk isn’t being managed
- Nobody can produce a current list of vendors with access to sensitive data or systems
- Vendors are selected and onboarded on price and features alone, with no security review
- Contracts don’t specify what happens (notification timelines, liability) if the vendor is breached
- No one revisits vendor risk after initial onboarding — a vendor’s security posture at signup is treated as permanent
- Access granted to a vendor is broader than what they actually need to do their job
Practical guidance
Start with an inventory — you can’t manage risk you haven’t listed. Tier vendors by what they can access, apply a proportionate review (a quick questionnaire and a SOC 2 check for most, deeper diligence for the few with the most sensitive access), and revisit the highest-risk vendors at least annually rather than treating the initial review as permanent.

Not necessarily on day one — a simple inventory and tiered review of your highest-access vendors gets most of the risk reduction without the overhead of a full formal program, which usually becomes worth building as vendor count and regulatory exposure grow.
It’s a strong signal and a reasonable starting bar for most vendors, but it’s not a guarantee — read the scope and any exceptions noted in the report rather than treating the existence of a SOC 2 alone as sufficient.
At least annually for your highest-risk vendors — those with access to sensitive data or critical systems — with lighter-touch or less frequent review for lower-risk tools.
That doesn’t automatically mean ending the relationship, but it should shape how much access they’re given, what contractual protections you require, and how closely you monitor the relationship going forward.
