HIPAA Compliance Checklist for 2025
You may know which vendors your company uses. But do you know what they can actually access?
SecurityScorecard’s 2026 research found that 78% of organizations cover less than half of their vendor ecosystem through their cybersecurity programs.
That gap is where third-party cyber risk can hide. A vendor may be approved, yet its application can still create exposure through access, integrations, identities, data, or fourth-party dependencies.
Third-party cyber risk management focuses on that exposure: what a third party can reach, how the risk changes over time, and what your security team can do before it becomes an incident.
1. What is Third-Party Cyber Risk Management?
Third-party cyber risk management (TPCRM) is the process of identifying, assessing, monitoring, and reducing cybersecurity risks introduced by external vendors, SaaS applications, cloud providers, and other third parties.
It focuses on what a third party can access, what it connects to, and how that exposure changes over time. The goal is to spot and reduce cyber risk before it becomes a security incident.
“CISOs should create a strategy that uses indirect monitoring to spot potential risks in a third party’s security posture and direct monitoring to track risks through internally exposed services.” — Rahul Balakrishnan, Senior Director Analyst, Gartner, 2026
2. What is the Difference Between Third-Party Cyber Risk Management and Vendor Risk Management?
Vendor risk management (VRM) looks at the overall risk of working with a vendor. Third-party cyber risk management (TPCRM) focuses on the security exposure that relationship creates.
VRM may cover financial health, contracts, compliance, reputation, and service performance. TPCRM looks at the technology behind the relationship, including access, integrations, data, identities, and security weaknesses.
The difference matters because a vendor can look fine on paper while its application creates security risk. Broad permissions, risky integrations, exposed API keys, or unmanaged identities can turn a routine vendor relationship into a real attack path.
3. How Should You Prioritize Third-Party Cyber Risk?
Not every third party deserves the same level of scrutiny. Start with the ones that can cause the most damage if compromised.
Look at five things:
- Access: Can the third party reach production systems, identity infrastructure, or privileged environments?
- Data: Does it handle customer, financial, employee, health, or other sensitive data?
- Business impact: How badly would an outage affect critical operations?
- Connectivity: How many applications, APIs, integrations, and identities does it connect to?
- Dependency: How difficult would it be to replace the vendor or move the workload?
A vendor with limited access and low business impact can follow a lighter review. A provider connected to production systems and sensitive data needs deeper due diligence and closer monitoring.
Risk tiering should determine the depth of assessment, monitoring frequency, and response requirements, not just assign a label. NIST CSF 2.0 also recommends adjusting assessment format and frequency based on supplier reputation and the criticality of the products or services involved.

4. Why Can Traditional Vendor Reviews Miss Cyber Risk?
A traditional vendor review can tell you whether a company meets a set of security requirements. It may not tell you what changes after the vendor is connected to your environment. That gap can leave security teams with an outdated view of third-party exposure.
A. Point-in-Time Reviews Miss Changes
Most vendor assessments happen before onboarding or on a fixed annual cycle. But risk can change much sooner.
A new integration, broader permissions, new data source, product update, acquisition, or security incident can change the risk profile without waiting for the next review.
B. Vendor-Level Reviews Miss Application Risk
The vendor and its application are not the same risk object. A vendor may maintain strong corporate controls while its application has excessive permissions, open integrations, or access to sensitive systems.
The review should therefore ask not only “Is the vendor secure?” but also “What can its application do in our environment?”
C. Questionnaires Do Not Show Actual Exposure
A questionnaire captures declared controls. It does not provide a live view of who has access, which permissions are active, or which integrations are still connected.
That creates a common blind spot: the organization believes the vendor follows least privilege, while several users, admins, or integrations may still hold more access than they need.
D. Non-Human Identities Can Become Persistent Access Paths
Service accounts, API keys, OAuth tokens, bots, and AI agents often operate outside normal employee access reviews. When ownership is unclear or credentials remain active after a project ends, they can become long-lived paths into connected systems.
E. Vendor Inventories Can Miss Shadow SaaS and AI
Security teams cannot manage a third party they do not know exists. Employees can adopt SaaS or AI applications through self-service purchases, browser access, or OAuth connections before the tool reaches procurement or security review.
The core problem is visibility. A vendor questionnaire shows what the vendor says. A modern TPCRM program also needs to show what the relationship has actually created: applications, access, integrations, identities, and data exposure.
5. What Should a Third-Party Cyber Risk Management Program Include?
A good TPCRM program should help security teams answer three things: which third parties matter, what can they access, and what happens when that risk changes.
It should cover:
- Third-party inventory: Know which vendors, SaaS tools, cloud services, and other external providers are actually in use.
- Risk tiering: Rank them based on data, access, business impact, and technical exposure.
- Security checks: Review controls, incidents, vulnerabilities, certifications, and supporting evidence.
- Access and identity: Track users, privileged accounts, OAuth connections, API keys, service accounts, and other non-human identities.
- Ongoing monitoring: Watch for changes in access, integrations, security posture, vulnerabilities, and fourth-party dependencies.
- Response and remediation: Have a clear path to investigate, restrict access, fix the issue, or accept the risk.
- Reassessment and exit: Review the relationship when something changes and remove access, credentials, and integrations when it ends.
The important part is that these pieces work together. A risk rating alone does not tell you whether a vendor has excessive access or an unmanaged identity sitting inside your environment.
6. How Should TPCRM Handle SaaS and AI Applications?
SaaS and AI tools have changed what counts as a third-party cyber risk. The concern is no longer just the vendor’s security program. The application may have access to company data, internal systems, APIs, and identities.
For SaaS and AI applications, review:
- Data access: What sensitive data can users upload, share, or store?
- Permissions: What can the application read, change, or trigger?
- Integrations: Which systems are connected through APIs or OAuth?
- AI behavior: How are prompts, files, and outputs handled? Can an AI agent take actions without approval?
- Non-human identities: Are API keys, tokens, service accounts, or agents created?
- Actual use: Are employees using the application in ways security teams did not approve?
This also makes it important to separate the vendor from the application. Anthropic is the vendor. Claude is the application. Both need to be understood, but the application's access and usage determine much of the exposure inside your environment.
The goal is simple: know what the application can touch, what it can do, and who or what can act through it.
7. How Does TPCRM Align With NIST CSF 2.0?
NIST CSF 2.0 puts third-party cybersecurity under GV.SC, Cybersecurity supply chain risk management. The framework says supplier risks should be understood, recorded, prioritized, assessed, responded to, and monitored throughout the relationship.
For TPCRM, that means:
- Identify: Know which suppliers and services matter.
- Assess: Review their security, access, data, and dependencies.
- Set requirements: Put security expectations into contracts.
- Monitor: Watch for changes in exposure and supplier risk.
- Respond: Investigate and reduce material risks.
- Exit: Remove access and dependencies when the relationship ends.
The important point is that NIST's model does not stop at due diligence. It expects organizations to keep assessing supplier risk as the relationship changes
8. How Should Third-Party Cyber Risk Be Managed During Renewal and Offboarding?
Renewal is a security checkpoint, not just a procurement date. Recheck whether the vendor still needs the same access, data, integrations, and privileges.
Review:
- Open security findings and recent incidents
- Current user and privileged access
- APIs, integrations, and non-human identities
- Data still handled by the vendor
- Actual usage and business criticality
When the relationship ends, verify the technical cleanup. Revoke credentials, disconnect integrations, disable service accounts, and confirm data deletion or return.
This matters because a contract ending does not automatically remove technical access. Gartner's 2026 TPCRM guidance specifically calls out cyber-risk reassessment, business continuity updates, contract changes, and third-party offboarding as distinct activities.
9. How Does CloudEagle Help Manage Third-Party Cyber Risk?
Third-party cyber risk is difficult to manage when application, access, security, and usage data sits in different places. CloudEagle.ai brings these signals together so security teams can see which third-party applications are in use, what they can access, and where the exposure needs attention.
Teams can use CloudEagle to:
- Discover SaaS and AI applications, including tools that bypass normal procurement or SSO.
- See application access and permissions across users and connected systems.
- Find non-human identities such as API keys, service accounts, and tokens.
- Connect usage with security risk to spot applications that are widely used or handling sensitive data.
- Support remediation and renewal decisions with current risk and usage context.
Real-World Example:
Lapzo had 26 approved AI vendors, but CloudEagle.ai found 115 AI tools in use within its first 10 days. It identified 89 high-risk AI applications, including four processing regulated customer data without a signed DPA. CloudEagle built a full AI inventory in one day.
The lesson is important for TPCRM: an approved vendor list is not the same as your real third-party footprint. You need to know which applications are actually being used and what data or systems they can reach.
10. Conclusion
Vendor approval is not the same as cyber risk management. Third-party cyber risk management looks beyond the vendor to the applications, access, integrations, identities, and data the relationship brings into your environment.
The goal is straightforward: know where third-party exposure exists, spot meaningful changes early, and act before that exposure becomes an incident.
Third-Party Risk Starts With Visibility
11. FAQs
1. What is third-party cyber risk management (TPCRM)?
Third-party cyber risk management refers to the process of identifying, analyzing, monitoring, and mitigating the cybersecurity risks posed by vendors, SaaS solutions, cloud providers, and any other outside parties.
2. How is TPCRM different from vendor risk management?
Vendor risk management is concerned with the business relationship as a whole, taking into consideration not only the financial but also legal, operational, and compliance risks associated with the vendor. TPCRM, in turn, takes into account only the cybersecurity risks.
3. What should organizations monitor in third-party cyber risk management?
Keep track of potential events that could lead to increased exposure such as new vulnerabilities, security incidents, privileged access, API integrations, OAuth grants, exposed credentials, new sub-processors, and updates to the applications and data that the third party may access.
4. How should organizations prioritize third-party cyber risk?
Begin with third parties that pose the biggest risks by having access to important systems, sensitive data, and business processes. This risk-based approach allows security teams to focus on those vendors that would cause significant damage should there be any breach.
5. What does a third-party cyber risk management platform do?
TPCRM solution will help you centralize all third-party inventories, assessments, monitoring, risk detection and remediation. More sophisticated strategies allow linking of external vendor intelligence with technical exposure so that one can get from "this vendor is risky" to "this is the exposure we need to remediate."
