Building TPRM Program for a Software Company
Software companies rely on third parties to host infrastructure, process payments, manage data, support development, and operate critical business functions. Each relationship creates risk, but treating every vendor as equally risky creates a different problem: a slow, expensive TPRM program that business teams learn to avoid.
An effective third-party risk management program not only eliminates risk; it helps the company identify which risks matter, make informed decisions, assign accountability, and monitor critical relationships throughout their lifecycle.
Here is a practical thoughts for building a TPRM program without creating unnecessary bureaucracy.
Start with the Business, Not the Questionnaire
Many TPRM programs begin by selecting a security questionnaire. Before doing that, understand how the company uses third parties and what could go wrong (determine the real risk).
For a software company, key exposures may include:
Loss or misuse of customer, employee, or proprietary data
Unauthorized access to systems, source code, or production environments
Service interruptions affecting customers or operations
Privacy, security, or regulatory noncompliance
Dependence on a single critical provider
Financial, legal, operational, and reputational damage
Risks introduced by a vendor's subcontractors or sub-processors
Meet with Security, Privacy, Legal, Procurement, Finance, Engineering, Compliance, and Operations. Identify which vendors they use, what information those vendors receive, what systems they can access, and which services the company cannot operate without.
This work should produce three foundational items:
A documented TPRM policy
A consistent risk assessment methodology
A reliable inventory of third parties and business owners
Without these foundations, even an advanced TPRM platform will only automate an inconsistent process.
Define Scope and Ownership
The program should define what qualifies as a third party and which relationships require review. The scope may include SaaS providers, cloud platforms, contractors, payment processors, data providers, managed services, development tools, artificial intelligence providers, and strategic partners.
TPRM should coordinate the process, but it should not own every vendor or every risk. The business owner remains accountable for the relationship. Security, Privacy, Legal, Compliance, and other specialists assess risks within their areas. And authorized risk owner approves any residual risk.
Create a Risk-Based Intake Process
TPRM should begin before a contract is signed or access is granted. Keep the intake form short, but collect enough information to determine the appropriate review:
What service will the vendor provide?
What business process or product will it support?
Will it access, store, process, transmit, or generate company data?
What types of data are involved?
Will it connect to internal systems or production environments?
Could an outage affect customers or critical operations?
Will it use AI or share data with subprocessors?
Whenever possible, embed intake into procurement, contracting, accounts payable, or access-management workflows. This reduces off-process purchases (shadow procurement) and prevents vendors from becoming operational before review is completed.
Tier Vendors by Risk and Criticality
Not every vendor needs a lengthy questionnaire. A tiering model focuses the team's effort where failure would cause the most harm.
Tier 1: Critical
The vendor supports essential operations, handles highly sensitive data, has privileged access, or could create material customer or regulatory impact. It requires comprehensive due diligence, stronger contract terms, ongoing monitoring, and executive visibility.
Tier 2: High Risk
The vendor processes sensitive information or connects to important systems but is not essential to continued operations. It requires a detailed review and periodic reassessment.
Tier 3: Moderate Risk
The vendor has limited access or business impact. A targeted assessment and review of relevant evidence may be sufficient.
Tier 4: Low Risk
The vendor does not access sensitive information or important systems and would cause little impact if it failed. Basic screening and documented approval may be enough.
Consider both inherent risk and business criticality. A vendor can be operationally critical without processing sensitive data, while a noncritical application can still present significant security or privacy risk.
Match Due Diligence to the Risk
Assessments should use evidence rather than relying only on self-reported questionnaire answers. Depending on the vendor, review materials such as:
SOC 1 or SOC 2 reports
ISO 27001 certifications
Penetration-test summaries
Business continuity and disaster recovery plans
Privacy documentation and data flows
Subprocessor lists
Cyber insurance certificates
Financial information
Architecture and integration details
Possessing a SOC 2 report does not automatically make a vendor acceptable. Review its scope, covered systems, audit period, exceptions, complementary user entity controls, and remediation commitments. Questionnaires should also be targeted. A payroll processor, cloud provider, law firm, and marketing platform should not receive identical assessments.
Turn Findings into Decisions
Every material finding should include a risk description, supporting evidence, severity, owner, remediation plan, target date, and final disposition.
The company generally has four options: require remediation, add a compensating control, accept the risk, or decline the relationship. Risk acceptance should identify the business justification, approving authority, affected assets or data, expiration date, and any conditions attached to the approval. It should not become a permanent shortcut around the review process.
Due diligence should also inform contract negotiations. Depending on the relationship, contracts may need security and privacy requirements, incident-notification timelines, audit rights, recovery expectations, subprocessor obligations, data-deletion terms, insurance requirements, and termination rights.
Monitor Vendors After Approval
Vendor approval is not the end of the process. Products, ownership, infrastructure, subprocessors, and financial conditions change. The company's use of the vendor may also expand. Ongoing monitoring should be based on tier and may include:
Periodic reassessments
Updated assurance reports and certifications
Tracking of remediation items
Security, financial, or operational monitoring
Review of outages/incidents and open issues
Changes to data use, integrations, subprocessors, or hosting locations
Confirmation that the vendor remains necessary and properly tiered
Do Not Ignore Offboarding
When a relationship ends, verify that access, credentials, tokens, and integrations have been removed. Confirm that company data and assets have been returned or destroyed, payments have stopped, and retention obligations have been addressed. Critical vendors should also have an exit strategy covering data portability, transition support, alternative providers, and business workarounds.
Final Thoughts
Building a TPRM program for a software company is an exercise in prioritization. The company will always have more vendors and potential risks than the team can examine with equal depth.
Start with a reliable inventory, clear ownership, practical tiering, and an intake process that begins before commitment. Then add deeper assessments, monitoring, metrics, and automation as the program matures.
The strongest TPRM programs do not create the most paperwork. They consistently identify material risks, involve the right decision-makers, document accountability, and allow low-risk purchases to move quickly
