How can organisations decide whether to prioritise nonstandard application governance over new security tools?

Why This Matters for Security Teams

Choosing between nonstandard application governance and another security tool is really a decision about where the organisation’s biggest exposure lives. If critical workflows depend on legacy apps, shared accounts, hard-coded secrets, or custom integrations, more tooling can add telemetry without removing the root cause. NIST Cybersecurity Framework 2.0 stresses governance and risk prioritisation, which is why identity gaps in unusual systems often deserve attention before another control layer is purchased.

NHIMG research shows the problem is not theoretical. In The 2024 ESG Report: Managing Non-Human Identities, Oasis Security & ESG found that 72% of organisations have experienced or suspect a breach of non-human identities. That matters because nonstandard application estates often hide the exact identity weaknesses attackers exploit first: missing rotation, over-privilege, and poor visibility. When those applications support finance, marketing, or operational systems, the business impact rises quickly. In practice, many security teams discover nonstandard access paths only after an audit finding or credential abuse incident has already exposed them.

How It Works in Practice

Organisations should start by inventorying where standard identity protocols actually fail. The key question is not whether a tool can monitor the application, but whether the application can be governed through normal lifecycle, authentication, and authorization processes. If it cannot, governance should focus on reducing exception-driven access, eliminating long-lived secrets, and assigning clear ownership for each nonstandard app.

A practical decision path looks like this:

• Identify business-critical applications that cannot support modern identity controls such as SSO, SCIM, or federated access.
• Map who uses them, what secrets or shared credentials they depend on, and whether rotation is manual.
• Determine whether the main risk is access sprawl, weak logging, vendor exposure, or privilege accumulation.
• Apply compensating controls first when the environment cannot support standardisation quickly.
• Use new security tools only when they directly close a control gap that governance cannot remediate.

This approach aligns with the lifecycle mindset in Ultimate Guide to NHIs — Lifecycle Processes for Managing NHIs, because the priority is to make the identity estate governable before layering on extra detection. It also fits NIST Cybersecurity Framework 2.0 by treating asset ownership, access control, and risk treatment as prerequisites for tool selection. If a system cannot be brought under basic identity governance, a tool may only mask the exception rather than reduce it. These controls tend to break down in heavily customised ERP, manufacturing, and acquired-legacy environments because identity integration is constrained by vendor design and operational downtime risk.

Common Variations and Edge Cases

Tighter governance often increases operational overhead, so organisations have to balance immediate risk reduction against process friction and business continuity. That tradeoff is most visible when systems are old, highly bespoke, or embedded in third-party workflows. In those cases, current guidance suggests prioritising governance if the application is business-critical and the identity model is the weakest control point.

There is no universal standard for this yet, but the rule of thumb is straightforward: if the application can be standardised within a reasonable timeframe, a new security tool may be justified after the governance baseline is in place. If standardisation is unlikely, the security team should focus on compensating controls, access reviews, secret rotation, and auditability. NHIMG’s Top 10 NHI Issues is useful here because it highlights how over-privilege and poor lifecycle control often outrank tool coverage as root causes. The practical test is whether the organisation is buying visibility, or buying time to avoid fixing a known identity gap.
