Start with the applications that hold the highest business and privilege risk, then verify whether identity teams can request, approve, certify, and revoke access through one governed path. The goal is not connector count. It is whether the integration lets the programme enforce policy consistently across the systems that matter most.
Why This Matters for Security Teams
Application connectivity is where identity governance becomes operational. A connector to a business-critical system is not just a technical integration; it is a control path for request, approval, certification, and revocation. If identity teams prioritise low-risk apps first, they can end up with a large connector inventory and little policy consistency where it matters most. Current guidance suggests starting with the apps that concentrate privilege, data sensitivity, or regulatory exposure, then proving the governed path end to end.
This is especially important for non-human identity and service-account-heavy environments, where access tends to expand quietly through APIs, automation, and delegated admin tools. NHIMG’s Ultimate Guide to NHIs frames lifecycle control as the real governance problem, not connector volume, and the NIST Cybersecurity Framework 2.0 reinforces the need to manage identity risk in line with business impact. In practice, many security teams discover connector sprawl only after access reviews, approvals, and revocation paths have already diverged across the most sensitive systems.
How It Works in Practice
Prioritisation should begin with a simple mapping exercise: identify applications by business criticality, privilege concentration, and failure impact. The first connectors should support systems where access governance can reduce the most risk, such as SaaS platforms with broad delegated access, infrastructure consoles, code repositories, ticketing systems, and finance or customer data systems. The question is not whether an app can connect, but whether the connection lets identity teams enforce policy consistently from request through revocation.
For each candidate application, test the governed path against a few practical checks:
- Can access be requested through the identity programme rather than a separate workflow?
- Can approvals use the same policy logic across similar applications?
- Can certifications and recertifications see the full entitlement context?
- Can revocation happen automatically, not just through manual ticketing?
- Can the integration distinguish human access from NHI access where both exist?
The OWASP Non-Human Identity Top 10 is useful here because many of the hardest failures involve over-privileged machine access, poor secret handling, and missing lifecycle controls. NHIMG’s Top 10 NHI Issues also shows why visibility and rotation matter when the connector reaches systems that do not expose clean entitlement data. A practical prioritisation model usually combines risk score, governance feasibility, and dependency count so the team can land one controlled pattern and reuse it. These controls tend to break down when legacy platforms expose only partial APIs because access and revocation then revert to manual exceptions.
Common Variations and Edge Cases
Tighter connector prioritisation often increases implementation effort, requiring organisations to balance fast coverage against depth of control. That tradeoff is real, especially when business units ask for broad integration while the identity team is still building policy standardisation. Best practice is evolving, but current guidance suggests avoiding the temptation to chase connector count as a programme milestone.
Edge cases usually appear in three places. First, some applications support request and approval but not certification or revocation, which means they may be useful for visibility but not yet suitable as a governance anchor. Second, some platforms have strong API coverage for humans but weak support for service accounts, OAuth apps, or shared technical identities. Third, highly distributed environments often need phased rollout by domain, not by product family, because the real risk sits in the access model rather than the software brand. NHIMG’s 52 NHI Breaches Analysis is a useful reminder that weak lifecycle control and invisible access paths are recurring failure patterns, not edge anomalies. If an application cannot participate in governed revocation, it should not be treated as a priority integration for access governance until that gap is closed.
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 and CSA MAESTRO address the attack and risk surface, while NIST CSF 2.0 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-01 | Prioritises high-risk app connectors where machine access is easiest to abuse. |
| NIST CSF 2.0 | PR.AC-4 | Access approvals and revocation need consistent identity governance across key systems. |
| CSA MAESTRO | GOV-02 | Governance of agentic and machine access depends on controlled integration paths. |
Apply least-privilege and governed access paths to the highest-impact applications first.
