What should CIOs prioritise first when remote work expands the identity surface?

Which identity paths deserve first attention as work becomes remote?

The first priority is not every login path, it is the small set that lets remote users reach sensitive cloud resources from unmanaged or lightly controlled endpoints. Those paths usually carry the highest blast radius because trust is distributed across device health, user assurance, session handling, and cloud permissions. If you can narrow and harden those routes first, the rest of the identity surface becomes much easier to govern.

A practical way to think about this is to treat the path, not the user, as the unit of risk. A remote worker on a managed laptop behind strong conditional access is a different control problem from a contractor on a personal device accessing production data or admin consoles. The latter path deserves earlier scrutiny because one weak decision can expose multiple systems at once.

As the remote model expands, the same logic applies to shadow IT, low-code platforms, and automation tools. They are often introduced as productivity accelerators, but they also widen the number of identities, tokens, and approval paths that must be inventoried, reviewed, and revoked when conditions change.

Why unmanaged devices and cloud access create the highest exposure

Unmanaged endpoints make it harder to verify device posture, enforce revocation quickly, and trust the local environment where credentials are used. When that endpoint is also reaching cloud SaaS, admin portals, or data platforms, the identity control plane depends on assumptions that are difficult to observe in real time. That is why the first control question should be whether the access path can be authenticated, constrained, and withdrawn without depending on the endpoint behaving well.

Cloud resources raise the stakes because a single session can bridge collaboration tools, storage, source code, and administrative functions. Even a modest misstep in access design can turn one remote session into a broad entitlement problem, especially if the path uses reusable credentials or broad roles. The goal is to reduce how much access any one remote path can accumulate before it is re-evaluated.

For teams formalising those controls, the most useful baseline is to align identity assurance and session strength to the sensitivity of the resource. NIST SP 800-63 Digital Identity Guidelines is a good reference for thinking about assurance, authenticators, and phishing resistance, while NIST SP 800-53 Rev 5 Security and Privacy Controls anchors the broader access control and audit expectations around those sessions.

How to extend the same governance model beyond the first wave

Once the high-risk remote access paths are under control, extend the same governance model to every place where access is created faster than it is reviewed. Shadow IT, low-code platforms, and automation tools often bypass standard onboarding, ownership, and deprovisioning flows, which means they can accumulate access quietly. The issue is less the technology category than the control gap: who owns it, what it can reach, and how quickly it can be removed.

That is why inventory and ownership matter as much as authentication. If a platform can create tokens, service connections, or delegated access without a clear review point, it should be brought into the same lifecycle discipline as other identities and secrets. The more freely a platform can mint access, the more important it becomes to centralise approval, logging, and expiration.

For practitioners looking for a broader control baseline, CIS Controls v8 is useful for account management, access control, and inventory discipline, while NIST Cybersecurity Framework 2.0 helps structure the governance, protection, detection, and recovery view of the same problem. If remote work is changing your identity surface materially, Identity Security Programme Guide can help translate that into operating model and ownership decisions.

Practitioner Guidance

What to prioritise: Start with the access paths that combine unmanaged endpoints, sensitive cloud resources, and broad privileges. Those are the routes where a single weak control can create the largest unrecoverable exposure.

What to verify: Confirm that each high-risk path has clear ownership, enforceable revocation, and an auditable condition for access. If you cannot answer who can remove access quickly, the path is not yet governed well enough.

Decision rule: If a remote access route can reach production data or admin functions, treat it as a first-wave control candidate even if it represents only a small share of total users. Scale of impact matters more than user count.

Practitioner takeaway: The right first step is to shrink the number of remote paths that can combine weak device trust with strong resource access, then apply the same lifecycle discipline to every new platform that creates access faster than it can be reviewed.
