Vendor management skills expose the real vendor lifecycle gap

At a glance

What this is: This is a vendor management skills article that argues supplier relationships depend on communication, negotiation, project control, and lifecycle handling.

Why it matters: It matters to IAM practitioners because the article’s offboarding and access-revocation angle maps directly to vendor identity governance, external access control, and lifecycle discipline across NHI and human programmes.

By the numbers:

• Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them.
• 96% of organisations store secrets outside of secrets managers in vulnerable locations including code, config files, and CI/CD tools.
• 92% of organisations expose NHIs to third parties, raising concerns about supply chain security.

Context

Vendor management becomes an identity governance problem the moment external parties receive access, credentials, or contract-linked operational authority. The article is really about the skills people need to keep supplier relationships controlled, but its practical edge comes from how easily those relationships turn into access sprawl, weak offboarding, and unmanaged vendor profiles.

For IAM, PAM, and NHI teams, the interesting part is not the soft-skill framing. It is the lifecycle reality: vendors come and go, permissions change, and access often outlives the relationship unless there is a disciplined process for onboarding, review, revocation, and offboarding.

Key questions

Q: How should organisations govern vendor access as part of identity management?

A: Treat vendor access as a lifecycle-controlled identity, not as a loose operational convenience. Every external account, token, or delegated permission should have an owner, a purpose, an expiry condition, and a documented revocation path. That approach keeps procurement, security, and IAM aligned and makes offboarding enforceable instead of optional.

Q: Why do vendor relationships create identity governance risk?

A: Vendor relationships create risk because they often generate persistent access that survives the commercial relationship. If permissions are not reviewed and revoked promptly, the organisation keeps paying the operational cost while the identity still has reach into systems and data. The risk is access that no longer has a valid business justification.

Q: What breaks when vendor offboarding is handled informally?

A: Informal offboarding usually leaves behind active accounts, shared secrets, and unreviewed SaaS entitlements. That creates orphaned access with no clear owner and no reliable revocation record. Security teams then struggle to prove which third parties still have access, which is exactly where audit gaps and unauthorized use start to appear.

Q: Who should be accountable for third-party access removal?

A: Accountability should be shared between the business owner who approved the relationship and the identity team that enforces revocation. Procurement can confirm the contract status, but only the access owners can ensure credentials and entitlements are actually removed. Without that split, offboarding becomes a paperwork exercise instead of a control.

Technical breakdown

Vendor lifecycle management and access revocation

Vendor lifecycle management is the control pattern that governs a supplier from initial onboarding through active use and eventual offboarding. In identity terms, that means knowing what access the vendor has, why it exists, who owns it, and how it is removed when the relationship ends. The article’s description of giving and revoking access, tracking vendor inventory, and handling offboarding is really a lifecycle model, even if it is written in procurement language. Without explicit ownership and revocation steps, vendor profiles become durable access containers rather than temporary business relationships.

Practical implication: treat vendor offboarding as an identity control event, not a contract admin task.

Why vendor access becomes NHI governance

External vendor access often behaves like a non-human identity problem even when the relationship is human-managed. A supplier account, API key, SaaS admin seat, or delegated credential can persist independently of any employee and can be reused, forgotten, or over-scoped. That is why vendor management and NHI governance overlap so heavily. The technical issue is not the relationship itself, but the identity artefacts created to support it. Those artefacts need inventory, scope control, and retirement logic just like any other machine or third-party identity.

Practical implication: classify vendor-issued credentials and accounts inside your NHI inventory, not as informal exceptions.

Automation helps administration, not accountability

The article leans on automation for procurement, access, and offboarding, which is directionally right but incomplete. Automation can enforce workflow, logging, and revocation actions, but it cannot decide whether access is still justified or whether a vendor relationship should remain active. That decision requires governance, ownership, and periodic review. In practice, automated systems work best when they are bound to explicit identity rules, such as approval gates, revocation triggers, and evidence capture for audits. Otherwise, automation just makes bad lifecycle decisions faster.

Practical implication: automate vendor access workflows only after defining ownership, approval, and offboarding criteria.

NHI Mgmt Group analysis

Vendor management becomes an identity lifecycle problem the moment access is created. The article frames vendor management as relationship skill, but the governance risk sits in the access that relationship creates. Once a supplier gets credentials, seats, or delegated permissions, the control question changes from communication quality to lifecycle discipline. Practitioners should read this as a reminder that external access is never just commercial administration.

Vendor offboarding is the failure point that matters most. The article correctly mentions revoking access and removing vendor profiles, which is where many programmes break in practice. If offboarding is informal, vendor identities outlive the contract and continue to hold access that no longer has a business owner. That is a governance failure in identity terms, not merely a procurement oversight. Practitioners should treat vendor exit as a mandatory entitlement closure event.

External access should be governed as NHI, even when a person requested it. Supplier-linked accounts, API keys, and SaaS permissions behave like non-human identities because they persist beyond any single employee interaction. That means the same controls used for service accounts apply here: inventory, purpose limitation, entitlement review, and revocation. The practical conclusion is simple. If a vendor can sign in or call an API without a continuously owned lifecycle, the programme is already carrying hidden identity debt.

Automating vendor administration without lifecycle rules creates false assurance. The article’s automation examples are useful, but workflow automation alone does not guarantee that access is appropriate. The governance assumption being challenged is that a managed vendor relationship is the same as a controlled identity relationship. It is not. Practitioners should separate process efficiency from identity assurance and build explicit control points around access approval, review, and offboarding.

Vendor relationship skill is a control plane issue, not just a people issue. Communication, negotiation, and project management still matter, but only because they influence whether the organisation can enforce identity decisions consistently. A vendor manager who cannot coordinate ownership and evidence will not be able to retire access cleanly. The implication is that identity governance for third parties needs both commercial discipline and operational control.

From our research:

• 92% of organisations expose NHIs to third parties, raising concerns about supply chain security, according to Ultimate Guide to NHIs.
• Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them.
• That gap is why NHI Lifecycle Management Guide matters when vendor access must be removed cleanly.

What this signals

Vendor relationships need lifecycle controls, not just relationship management. The article is a reminder that supplier access becomes an identity problem as soon as credentials or SaaS permissions are issued. In practice, that means third-party access should be reviewed with the same discipline as any other privileged identity, especially where multiple teams share responsibility.

External access is easiest to govern when it is visible. NHI programmes that cannot inventory vendor-issued credentials will struggle to prove what a third party can reach or when that access should end. The control objective is simple: make every vendor account attributable, time-bound, and removable before it becomes operationally invisible.

92% of organisations expose NHIs to third parties, according to Ultimate Guide to NHIs, which means supplier access is already a mainstream governance issue. That reality pushes teams to formalise third-party onboarding, review, and offboarding rather than treating them as exceptions. The next step is to align those controls with NIST Cybersecurity Framework 2.0 governance and access functions.

For practitioners

• Map every vendor relationship to an identity owner Assign a named business owner and an IAM owner for each external vendor account, seat, token, or delegated connection. Require both owners to approve onboarding, access changes, and termination so no supplier identity exists without accountability.
• Inventory vendor-issued access as NHI assets Record SaaS admin seats, API keys, shared logins, certificates, and support accounts in the same inventory used for machine identities. Track purpose, expiry, business justification, and system owner so vendor access cannot disappear into procurement records.
• Trigger revocation on contract and relationship changes Tie offboarding workflows to contract end dates, scope changes, and vendor role changes. When the relationship ends or narrows, revoke access first and then close the administrative record so permissions do not outlive the business need.
• Review standing access for third parties quarterly Re-certify vendor permissions on a fixed cadence and verify that each entitlement still supports an active business task. Remove dormant access, reduce over-scoped permissions, and escalate any identity whose owner cannot be identified.

Key takeaways

• The article is really about vendor lifecycle control, and identity governance is the part that determines whether access stays justified.
• Third-party access often behaves like NHI risk, because accounts and tokens can persist long after the business relationship changes.
• Clean offboarding, clear ownership, and explicit revocation triggers are the controls that stop supplier access from becoming orphaned access.

Key terms

• Vendor Lifecycle Management: Vendor lifecycle management is the process of governing a supplier from onboarding to offboarding, including access, approvals, reviews, and removal. In identity programmes, it ensures the relationship stays tied to a current business need and that permissions do not remain active after the relationship changes.
• Third-Party Access: Third-party access is any credential, entitlement, or connection that lets an external supplier reach internal systems or data. It includes SaaS admin seats, API keys, shared accounts, certificates, and delegated access, all of which should be owned, reviewed, and retired like other identities.
• Identity Offboarding: Identity offboarding is the controlled removal of access when a person, vendor, system, or service no longer needs it. For suppliers, it requires revoking credentials, removing entitlements, closing shared accounts, and confirming that no residual access remains after the business relationship ends.
• Access Inventory: Access inventory is the authoritative record of who or what can reach systems, data, or applications. For vendor governance, it should capture account type, business owner, expiry, scope, and revocation path so external access is visible enough to manage and audit.
