TL;DR: The visible token bill is only a small part of the build vs buy AI decision, because production also adds reliability engineering, maintenance, audit logging, access control, and data-risk management around sensitive security workflows, according to ArmorCode. The deeper issue is governance: custom AI security tools become another identity- and operations-heavy system to secure, monitor, and sustain.

Questions worth separating out
Q: How should security teams decide what to build versus buy in an AI SOC?
A: Build the parts of AI SOC that encode your organisation's unique risk, architecture, and escalation logic.
Q: Why do AI agents create new risk in non-human identity management?
A: AI agents create risk because they operate as software identities with delegated authority, but many organisations do not track them with the same discipline applied to users or service accounts.
Q: What do teams get wrong about the cost of DIY AI security?
A: They usually count inference spend and ignore the surrounding operating model.
Practitioner guidance
- Define the production control boundary Document exactly which data, systems, and remediation actions any AI security workflow can access, then assign an owner for that boundary and its exceptions.
- Classify AI tools as NHIs Register every custom AI assistant, agent, or integration as a non-human identity with scoped permissions, credential ownership, and an offboarding path.
- Require audit-grade decision logs Capture who invoked the workflow, what findings were processed, what actions were suggested or taken, and how the model reached the output.

The build versus buy decision for AI security is fundamentally an identity governance decision. Once a model or agent can inspect findings, access internal data, or trigger remediation, it acquires the same governance burden as any other non-human identity. That means lifecycle management, permission scoping, secret handling, and auditability all become mandatory, not optional. Teams that frame this as a tooling choice miss the control-plane reality. The practitioner conclusion is simple: if the tool acts, it must be governed like an identity.
A question worth separating out:
Q: How do organisations keep AI security workflows auditable?
A: Log who initiated the action, what data the model used, what output it produced, and whether any downstream action was taken. Keep those records tied to identity so investigators can reconstruct decision paths. Without that linkage, accountability and forensic reconstruction become weak very quickly.
