Companies entering the US market move fast. They sign leases, open bank accounts, hire local staff, and adopt new software within weeks. Each new vendor relationship brings a security question that rarely gets asked during the rush: what access does this vendor have, and what happens if they get breached.
Vendor risk is not a new problem. It is, however, a problem that expands quickly during market entry, when the number of new supplier relationships spikes and internal review processes have not caught up.
A company opening its first US office typically signs with a new payroll provider, a new benefits administrator, a new IT support firm, and several SaaS tools chosen by local staff without central approval. Each of these vendors gains some level of access to company systems or employee data.
In an established company, vendor onboarding usually passes through procurement and security review. In an expanding company, speed takes priority. Local teams select tools that solve immediate problems, and security review happens after the fact, if at all.
This pattern creates a gap. The parent company's existing vendor risk program, built for its home market, often does not extend automatically to new US vendors. Nobody has assessed them.
Vendor breaches do not stay contained to the vendor. A breach at a payroll processor can expose employee social security numbers and bank details. A breach at a support ticketing vendor can expose customer data shared in tickets. A breach at a marketing platform can expose contact lists that feed directly into phishing campaigns against the company's own customers.
The 2023 breach at a major payroll and HR platform demonstrated this clearly, affecting client companies that had no direct control over the vendor's security practices but bore the consequences of the exposure.
Smaller vendors carry disproportionate risk. A five-person local IT contractor may have administrative access to a company's entire network with none of the security controls a larger provider would maintain.
A full enterprise vendor risk program is not realistic for a company in its first year of US operations. A lightweight, consistent process is achievable and far better than none.
Start with an inventory. List every vendor with access to company data or systems, including tools adopted informally by individual teams. This step alone often surfaces vendors that leadership did not know existed.
Classify by access level. A vendor with access to financial systems or employee personal data warrants more scrutiny than one providing office supplies. Focus review effort where exposure is highest.
Ask basic security questions before signing. Does the vendor have a written security policy. Have they had a breach in the past two years. Do they carry cyber insurance. Will they notify the company promptly if a breach occurs. These questions filter out vendors with no security maturity at all.
Put notification requirements in the contract. A vendor that discovers a breach affecting shared data should be contractually obligated to inform the company within a defined window, not whenever convenient.
Review access periodically. Vendors that no longer need system access, because a project ended or a tool was replaced, should have that access removed. Dormant access is a common entry point for attackers.
Vendor risk review is easiest to build correctly at the start of US operations, before dozens of informal tool choices accumulate. Companies that fold this into the market entry process, alongside legal and HR setup, avoid the harder task of retrofitting oversight onto an established web of vendor relationships later.
