Canadian SMBs depend on cloud platforms, payroll providers, IT companies, accountants, marketing systems, developers and industry-specific software. The objective is not to audit every supplier like a bank. It is to apply more scrutiny where the access and business impact are greater.
Classify the relationship
Record what the vendor will access, whether personal or confidential information is involved, whether the service is operationally critical, whether subcontractors are used and how difficult replacement would be.
Classify vendors as standard, controlled or critical. A newsletter platform and a managed administrator should not receive the same review.
Ask before access
- Is MFA enforced for vendor personnel?
- Are privileged actions attributable to named individuals?
- How is access approved, reviewed and removed?
- What security logging is available?
- How are vulnerabilities and updates handled?
- How are your data and backups protected?
- In which jurisdictions is information stored or processed?
- Will subcontractors receive access?
- How quickly will the vendor notify you of an incident?
- What happens to your data and accounts when the relationship ends?
Limit the access
Grant only the permissions, systems and duration required. Use separate named accounts, time-bound administrative access and technical restrictions where available. Avoid shared administrator credentials.
Document the internal owner. That person should know why the vendor has access, when it should be reviewed and who can terminate it.
Put expectations in writing
Contracts should reflect the sensitivity and operational importance of the service. Address security responsibilities, incident notification, cooperation, data handling, subcontractors, return or deletion of information, access termination and evidence the vendor must provide.
Monitor what changes
Vendor risk changes after onboarding. The provider may add a subcontractor, change hosting locations, experience an incident, introduce AI features or gain broader access. Review critical vendors at least annually and when material changes occur.
