Third-Party Risk as a Program.
Service overview
Most organizations don’t know which vendors have access to their critical systems — let alone whether those vendors can be trusted. Sitoo builds and runs your TPRM program end-to-end: vendor inventory, risk tiering, assessment, contractual controls, and ongoing monitoring. You get a defensible program your auditors, insurers, and partners will accept.
The Vendor Risk Nobody Is Actually Managing.
Third-party risk is the compliance checkbox that gets filled in with a spreadsheet and forgotten. Sitoo treats it as an operational program — defined ownership, repeatable assessment methodology, contractual enforcement language, and monitoring cadences that don’t collapse the moment a vendor sends back a questionnaire. The result is a program your auditors can test, your insurers can score, and your leadership can defend.
The Vendor You Trusted That You Shouldn’t Have.
A breach traced to a third-party vendor is still your breach — your regulatory obligation, your client notification, your reputational exposure. Most organizations have no formal vendor inventory, no risk tiering, no contractual security requirements, and no monitoring cadence. Sitoo closes every one of those gaps with a program built for your actual vendor population and risk tolerance.
Is This Right for Your Business?
What We Fix
No vendor inventory
You don’t have a complete list of which vendors touch your systems, data, or infrastructure. Managing vendor risk starts with knowing who your vendors actually are.
Questionnaires with no follow-through
You send SIG or custom questionnaires. Vendors respond. Nothing gets scored, nothing gets tracked, and high-risk findings sit in an inbox.
Contracts with no security teeth
Your vendor agreements have no right-to-audit clause, no breach notification SLA, no security baseline requirements, and no remediation obligations.
No monitoring after onboarding
Vendor risk is assessed once at onboarding and never revisited. Business relationships change, vendors get acquired, certifications lapse.
Deliverables & Scope
Every engagement produces defined, tangible deliverables. No open-ended hours.
Vendor Inventory & Tiering
Complete vendor population mapped, classified by data sensitivity, system access, and business criticality (Critical / High / Medium / Low).
Vendor Risk Assessments
Questionnaire-based scoring using SIG Lite, SIG Core, or custom methodology. Scored findings, identified gaps, and remediation tracking per vendor.
TPRM Program Documentation
Policy, procedure, workflow design, escalation criteria, and RACI — aligned to NIST SP 800-161r1 and ISO 27036.
Contract & Clause Review
DPA review, security addenda, right-to-audit language, breach notification SLAs, and SLA redlining for vendor agreements.
Ongoing Monitoring Program
Periodic reassessment cadences, trigger-based reviews (M&A, incidents, cert lapses), and defined re-tier criteria.
Executive & Audit Reporting
Board-level vendor risk dashboard, audit-ready evidence package, and regulator-defensible documentation.
How the Engagement Works
Vendor Inventory & Tiering
Complete inventory and tiering within 10 business days. Critical / High vendors identified for priority assessment.
Assessment & Program Build
Tier-appropriate assessments executed in parallel with program documentation. Findings scored, remediation tracked.
Monitoring Handoff or Retainer
Program transitioned to your team with full documentation, or run on retainer with defined cadences and trigger events.
What You Will Have at Engagement End.
A defensible vendor inventory
Every vendor with data or system access mapped, classified, and accounted for in a single authoritative source.
Tier-appropriate vendor assessments
Critical and High vendors assessed and scored. Findings tracked to remediation. No more questionnaires sitting in an inbox.
Contracts with security teeth
DPA language, right-to-audit, breach notification SLAs, and remediation obligations standardized across your vendor agreements.
A program your auditors will accept
Documentation, evidence, and reporting that satisfies SOC 2 (CC9.2), ISO 27001 A.5.19–23, NIST CSF (ID.SC), and DORA Article 28–30 requirements.
