TL;DR: Custom connectors let enterprises bring homegrown applications, databases, SCIM endpoints, and access control files into access governance workflows, including just-in-time access, reviews, and monitoring, according to Opal Security. The deeper issue is not connector variety but whether identity governance can keep pace with bespoke application sprawl.
NHIMG editorial — based on content published by Opal Security: Back Flexibility First: Four Classes of Custom Connectors for Engineering-Led Companies
By the numbers:
- The average employee uses 40 applications to do their job, typically a combination of in-house tools and third-party SaaS applications.
- Only 44% of organisations have implemented any policies to manage their AI agents, despite 92% agreeing that governing AI agents is critical to enterprise security.
- Systems with least-privileged AI access had a 17% incident rate vs 76% for over-privileged systems.
Questions worth separating out
A: Treat those applications as first-class governance targets, not exceptions.
Q: What breaks when custom connectors do not sync access changes reliably?
A: The governance record stops matching the real application state.
Q: Why do homegrown tools create more identity governance risk than standard SaaS apps?
A: They usually lack native lifecycle hooks, standard schemas, and predictable audit events.
Practitioner guidance
- Inventory every non-standard application first Classify homegrown apps, file-backed access systems, databases, and bespoke APIs by entitlement sensitivity, audit scope, and revocation urgency before deciding which ones need connectors.
- Choose the least brittle connector pattern Use REST or SCIM where available, then fall back to database or file-based connectors only when the source system cannot support structured identity sync.
- Test revocation before production rollout Measure how long it takes a connector to remove access in the target system and verify the result against the source-of-truth record.

Custom connectors are becoming the control plane for application sprawl, not just a convenience layer. Engineering-led companies increasingly build tools that hold sensitive data but do not fit the standard SaaS integration model. That means identity governance has to reach into APIs, databases, and file-backed access systems if it is going to remain credible. The practitioner takeaway is that connector strategy is now part of access architecture, not a back-office integration task.
A few things that frame the scale:
- Only 44% of organisations have implemented any policies to manage their AI agents, despite 92% agreeing that governing AI agents is critical to enterprise security, according to The 2026 Infrastructure Identity Survey.
- A separate finding shows that systems with least-privileged AI access had a 17% incident rate versus 76% for over-privileged systems, which is a 4.5x difference in incident likelihood.
A question worth separating out:
Q: Who should own connector security and access review quality?
A: Ownership should sit jointly with IAM or IGA for governance design and with the application team for system specifics. The connector is privileged infrastructure, so changes to routing, sync logic, and runtime access should follow the same approval discipline as other high-risk identity controls.
