A managed advertising identity used to create, control, and pay for ad campaigns across platforms such as Google, Facebook, or LinkedIn. In security terms, it is a privileged identity because it can spend money, publish externally visible content, and often connect to other enterprise systems through shared identity infrastructure.
Expanded Definition
An ad manager account is more than a billing container or campaign console. In NHI security, it functions as a privileged operational identity that can create campaigns, approve spend, publish externally visible content, and sometimes delegate access to other users or systems. That makes it closer to a high-impact service identity than a simple business profile. The security question is not just who logs in, but what authority the account carries, what it can connect to, and how tightly its actions are governed.
Usage is still evolving across platforms, because some organisations treat the account as a shared business asset while others model it as a delegated administrative identity. For governance purposes, NHI Management Group recommends the stricter interpretation: if the account can move money, change public-facing assets, or grant access, it deserves the same lifecycle controls applied to other privileged NHIs. That includes ownership, offboarding, review, and secret hygiene, as described in the Ultimate Guide to NHIs — Lifecycle Processes for Managing NHIs and the NIST Cybersecurity Framework 2.0.
The most common misapplication is treating the ad manager account as a normal marketing profile, which occurs when multiple teams share it without clear ownership or revocation controls.
Examples and Use Cases
Implementing ad manager account governance rigorously often introduces workflow friction, requiring organisations to weigh faster campaign execution against tighter approval, monitoring, and access controls.
- A growth team uses one ad manager account to run campaigns across Google and LinkedIn, but security requires named ownership, MFA, and periodic entitlement review because the account can spend budget and alter brand messaging.
- An agency manages multiple client ad accounts from a central console, creating a need for role separation so billing rights, creative publishing rights, and audit access are not all bundled into one identity.
- A compromised email inbox is used to reset access to the ad manager account, which is why identity recovery paths and delegated admin permissions must be reviewed as part of the account’s lifecycle, not after a loss event.
- An enterprise connects the ad manager account to CRM or analytics systems, making it a bridge identity that must be tracked in the same way NHI lifecycle tooling tracks service-account dependencies in the NHI Lifecycle Management Guide.
- Misconfigured access leads to unauthorized campaign edits or fraudulent ad spend, a pattern consistent with the control failures discussed in Top 10 NHI Issues and the identity governance expectations in NIST Cybersecurity Framework 2.0.
Why It Matters in NHI Security
Ad manager accounts matter because they concentrate financial authority, public trust, and platform access in a single identity surface. If that identity is shared informally, reused across teams, or left without offboarding discipline, it becomes an attractive target for abuse, fraud, and account takeover. NHI Management Group research shows that 97% of NHIs carry excessive privileges, and that pattern is especially dangerous here because the account can directly create spend and external exposure. The same research notes that 80% of identity breaches involved compromised non-human identities such as service account and API keys, which helps explain why these accounts should be governed as privileged NHI assets rather than marketing conveniences.
For audit and resilience teams, the key issue is traceability. Who approved a campaign? Who can pause spend? Which connected systems inherit the account’s authority? These questions map directly to governance expectations in the Ultimate Guide to NHIs — Regulatory and Audit Perspectives and the identity control principles in the NIST Cybersecurity Framework 2.0. Organisations typically encounter the need to treat an ad manager account as a privileged identity only after unauthorized spend, brand misuse, or a platform lockout forces incident response.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP Non-Human Identity Top 10 address the attack and risk surface, while NIST CSF 2.0 and NIST Zero Trust (SP 800-207) set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-01 | Ad manager accounts are privileged NHIs requiring ownership, lifecycle, and access control. |
| NIST CSF 2.0 | PR.AA | Identity and access governance covers privileged accounts that can spend and publish. |
| NIST Zero Trust (SP 800-207) | AC-1 | Zero Trust requires verifying every privileged identity and its connections before use. |
Assign ownership, rotate access, and revoke unused ad manager accounts like other privileged NHIs.
