What is third party risk management?

Third Party Risk Management: Why It's Now a Board-Level Priority

“I’ve been losing sleep. Things are changing so fast when it comes to third-party risk, compliance, and digital resilience.”

And we hear this across the board.

With DORA enforcement on the horizon, AI governance rising, and the average company relying on hundreds of external vendors, risk isn’t just internal anymore. It’s everywhere — and the old playbook of static spreadsheets and annual vendor surveys isn’t going to cut it.

So what’s really going on?

  • Regulatory frameworks like DORA, GDPR, and NIS2 are now demanding continuous monitoring — not just checkbox due diligence.
  • CEOs want assurances that third-party outages won’t tank operations or breach customer trust.
  • And risk, procurement, and IT teams are all pulling in different directions.

Let’s reset the conversation.

What is Third Party Risk Management?

Third Party Risk Management (TPRM) is a structured approach to identifying, assessing, mitigating, and continuously monitoring risks introduced by external vendors, suppliers, and service providers. These third parties often have access to sensitive data, business-critical systems, or internal processes — and any lapse on their part can expose your organization to cyber threats, compliance violations, or operational failures.

Unlike traditional vendor management, which focuses on cost and performance, TPRM zooms in on risk. It includes lifecycle governance — from pre-contract due diligence to offboarding.

Key components of a modern TPRM program include:

  • Risk-based vendor categorization
  • Standardized and scalable assessments
  • Continuous monitoring and alerts
  • Integration with broader risk and compliance frameworks
  • Documentation and defensibility for audits

Why Third Party Risk Management Matters

As third-party ecosystems expand and regulators tighten expectations, the risks increase exponentially. A vendor’s weak password policy can become your breach. A subcontractor’s outage can ripple into your customer experience. A lack of documentation can become a €10M GDPR fine.

Here’s why TPRM is mission-critical:

  • Compliance: DORA, GDPR, and ISO standards now require documented and monitored third-party oversight.
  • Cybersecurity: Third parties are often the weakest link in the security chain.
  • Operational resilience: Vendor outages can cripple core business functions.
  • Reputation management: Ethical or security lapses at third parties reflect back on you.
  • Investor confidence: Risk oversight is now part of due diligence in M&A and funding rounds.

How TPRM Works: Lifecycle View

TPRM isn’t a one-off audit. It’s an ongoing lifecycle process:

  1. Vendor Inventory: Create a central register of all vendors, suppliers, and partners.
  2. Risk Tiering: Categorize vendors based on criticality and access level (data, system, process).
  3. Due Diligence: Conduct assessments tailored to the vendor’s risk tier.
  4. Contracting: Include risk clauses (e.g., security controls, breach notification, audit rights).
  5. Monitoring: Track compliance, SLA adherence, incidents, and changes in risk profile.
  6. Remediation: Follow up on findings and ensure documented mitigation.
  7. Offboarding: Secure exit strategies, revoke access, and clean up dependencies.

Many organizations start manually but quickly graduate to GRC platforms like CERRIX for scale, automation, and audit readiness.

Types of Third Party Risks

Risk Tier Formal Assessment Frequency Continuous Monitoring Event-Based Reviews
High / Critical Quarterly Daily or weekly alerts Immediately upon trigger events
Medium Semi-annually Monthly alerts Within 2 weeks of change
Low Annually Quarterly alerts Within 30 days of change

Risk-Based Review Frequency

How often should you reassess third-party risk?

Use a tiered framework based on vendor criticality:

Risk Tier Formal Assessment Frequency Continuous Monitoring Event-Based Reviews
High / Critical Quarterly Daily or weekly alerts Immediately upon trigger events
Medium Semi-annually Monthly alerts Within 2 weeks of change
Low Annually Quarterly alerts Within 30 days of change

Trigger events include:

  • Mergers, acquisitions, or leadership changes
  • Security incidents or data breaches
  • Service expansion or change in data handling
  • Regulatory changes or audit findings

Key Factors That Influence Review Frequency

Several variables shape how often you need to assess a third party:

  • Regulatory Requirements (e.g., DORA mandates continuous oversight for critical ICT vendors)
  • Data Sensitivity (the more sensitive the data handled, the higher the risk)
  • Service Criticality (e.g., core banking, claims processing, or cloud hosting vs. catering)
  • Past Performance (history of incidents, SLAs missed, or audit findings)
  • Organizational Changes (mergers, leadership turnover, tech stack shifts)

Best Practices for TPRM Implementation

Building a TPRM program from scratch? Here’s a phased approach:

  1. Establish Governance: Define roles across 1st, 2nd, and 3rd lines of defense.
  2. Build a Vendor Inventory: Know who your vendors are and what they access.
  3. Create a Risk Scoring Framework: Automate tiering based on access, criticality, and compliance.
  4. Standardize Assessments: Use templates and tools for consistency.
  5. Automate Monitoring: Use platforms like CERRIX to alert you when something changes.
  6. Integrate with Procurement: Embed TPRM into onboarding and contract renewal.
  7. Audit-Ready Documentation: Ensure you can show your process to regulators or customers.

TPRM vs. Vendor Management: What’s the Difference?

Aspect Vendor Management Third Party Risk Management (TPRM)
Primary Focus Commercial performance, costs, contract terms Risk identification, assessment, and mitigation
Typical Ownership Procurement or operations departments Risk, compliance, or security functions
Lifecycle Coverage Procurement to payment processes Pre-engagement through offboarding
Assessment Approach Focused on service delivery and costs Risk-tiered evaluations across multiple domains
Regulatory Connection Limited regulatory considerations Strong alignment with compliance requirements

Technology’s Role in Modern TPRM

Manual tracking doesn’t scale. That’s why more organizations are turning to platforms like CERRIX to:

  • Centralize vendor data
  • Assign risk tiers automatically
  • Send, score, and track due diligence forms
  • Monitor changes via APIs, integrations, or KRI alerts
  • Track control effectiveness and link to incidents
  • Produce real-time dashboards for audit and board-level oversight

Key Takeaways for Strong TPRM

  • TPRM is not optional — it’s a business-critical discipline.
  • Risk-based tiering lets you focus where it matters most.
  • Continuous monitoring is now expected, not exceptional.
  • Third-party failures are your failures in the eyes of regulators and customers.
  • Technology turns reactive firefighting into proactive control.
