TL;DR: Ransomware attacks on U.S. critical infrastructure climbed 9% in 2024, while healthcare workers lose 13 minutes per shift to login friction and 47% of organisations reported a third-party breach last year, according to the FBI, Imprivata, and Ponemon Institute. Access design is now an operational security control, not just a usability concern.
At a glance
What this is: This analysis links inefficient access in critical industries to higher operational friction, credential sharing risk and expanded attack surface across frontline environments.
Why it matters: IAM teams in healthcare, manufacturing, energy and similar sectors need access flows that protect shared workstations, vendor access and shift-based workers without pushing people toward insecure workarounds.
By the numbers:
- Ransomware attacks on U.S. critical infrastructure climbed 9% in 2024.
- In healthcare alone, clinicians lose an average of 13 minutes per shift just logging in.
- 47% of organizations experienced a third-party breach last year.
Context
Critical industry access friction is what happens when authentication, device sharing and vendor access are not designed around how frontline teams actually work. In healthcare, manufacturing and energy environments, that mismatch pushes people toward workarounds such as shared credentials, repeated logins and lingering sessions on shared workstations.
The article argues that the access problem is both a productivity and security issue. When login processes slow clinicians, operators and first responders, the result is more frustration, more unsafe behavior and a larger attack surface across hybrid environments that still rely on legacy systems.
Key questions
Q: What breaks when frontline access controls are designed for office users instead of shift workers?
A: When access controls assume a private laptop, a single user and long uninterrupted sessions, frontline teams compensate with shared logins, session reuse and manual workarounds. That creates both security exposure and operational delay. The fix is not more friction, but access design that matches shared-device reality and fast task handoffs.
Q: Why do over-privileged vendor accounts increase breach risk in critical industries?
A: Over-privileged vendor accounts expand the number of systems an outsider can touch and make revocation harder to govern. In hybrid environments, that reach is especially dangerous because support access is often provisioned quickly and reviewed slowly. The practical risk is not only misuse, but entitlement drift that outlives the business need.
Q: How do security teams know if identity friction is becoming a risk?
A: They should watch login duration, failed authentication, device utilisation, and the volume of manual exceptions. Rising friction metrics often indicate that users are working around controls or abandoning secure workflows. That is an early signal that the access design is misaligned with how people actually work.
Q: Should organisations prioritise passwordless or privileged access modernisation first?
A: Most organisations should modernise privileged access controls first or in parallel, because the highest risk usually sits in service accounts, root access and shared administrative paths. Passwordless can improve user experience, but it does not address over-privilege, shared credentials or poor auditability on its own.
Technical breakdown
Why legacy authentication creates more risk in hybrid critical environments
Legacy authentication schemes often assume a stable desktop user, a single device and a predictable session length. Critical industries now run on shared workstations, mobile devices and hybrid application stacks, so those assumptions break down. Complex passwords and cumbersome MFA add time at every handoff, which increases the chance that users reuse credentials, share logins or leave systems open between shifts. The security issue is not that authentication exists, but that the workflow and the control model no longer match the operating environment. When access is designed for convenience after the fact, the result is usually both slower work and weaker identity assurance.
Practical implication: redesign authentication around shift work, shared devices and fast re-entry rather than forcing legacy login patterns onto frontline operations.
How over-privileged vendor access becomes an identity blind spot
Third-party access is a recurring failure mode because manual provisioning tends to expand access faster than it is reviewed or removed. The article points to over-privileged vendor access as a driver of breach risk, which is consistent with a broader pattern in critical industries: external support accounts are granted too much reach and then left in place for convenience. In hybrid environments, those accounts can touch systems that frontline users depend on but security teams do not monitor closely enough. The blind spot is lifecycle control. If vendor access is not tied to a clear request, scope and revocation process, it becomes persistent privilege rather than temporary support access.
Practical implication: scope third-party access tightly, review it against business need and treat vendor offboarding as a security control, not an administrative afterthought.
Why passwordless and device-bound access change the control model
Passwordless authentication, tap-and-go badges, biometrics and device-bound passkeys change the control model by reducing the number of moments where a user must remember or retype a shared secret. That matters in frontline settings because the biggest risk is often not a sophisticated bypass, but a predictable human workaround under time pressure. Device-bound methods can improve both assurance and usability when they are paired with clear session design and access boundaries. The main architectural value is that authentication becomes faster without reverting to weak shared credentials. In critical industries, that is a practical way to lower friction while narrowing the conditions that lead to credential sharing and stalled workflows.
Practical implication: move high-friction users toward passwordless and device-bound methods where shared workstations and shift changes create repeated login pressure.
Threat narrative
Attacker objective: The objective is to exploit weak access practices to reach more systems with less resistance, then use that reach for ransomware, data theft or broader compromise.
- Entry occurs through inefficient access design that pushes frontline users toward shared credentials, reused passwords or unattended sessions on shared devices.
- Escalation follows when over-privileged vendor accounts or lingering workstations provide broader access than the original task required.
- Impact shows up as larger attack surfaces, easier lateral movement opportunities and operational disruption in critical industries already under ransomware pressure.

NHI Mgmt Group analysis
Access friction is now a security control failure, not a user experience nuisance. In critical industries, every extra step in the login flow increases the odds of unsafe workarounds such as shared credentials or unattended sessions. That means the identity control plane is being shaped by operational pressure as much as by policy, and the result is a larger attack surface. Practitioners should treat authentication design as part of frontline risk management, not as a separate usability debate.
Vendor access without tight lifecycle control is a persistent exposure pattern. The article’s third-party breach figure points to a familiar governance gap: provisioning happens, but revocation and entitlement review lag behind. In environments where contractors and suppliers need rapid access, the problem is not the existence of third-party identity, but the drift between approved scope and real access. Practitioners should assume that unmanaged vendor reach will outlive the work it was created for unless lifecycle controls are explicit.
Passwordless access is becoming a workflow requirement for mission-critical work. Tap-and-go badges, biometrics and device-bound passkeys reduce the incentive to share passwords or leave sessions open, especially in shift-based settings. That is not a convenience upgrade. It is a way to align assurance with the pace of frontline operations and reduce the conditions that make insecure behavior rational. Practitioners should evaluate access methods by how well they fit shared-device reality.
Critical industries need identity design that matches the pace of the job. Healthcare, manufacturing and energy do not operate like office-bound knowledge work, yet many access policies still assume they do. The more the workflow diverges from the policy model, the more users compensate in ways security teams then have to clean up. Practitioners should re-evaluate authentication, vendor access and session handling together, because they fail together.
Identity blast radius expands when access is both cumbersome and over-broad. The combination of login friction and permissive vendor access creates a compound risk profile: users resist controls, while attackers inherit wider entitlement than necessary. That is a governance problem as much as a technical one. Practitioners should narrow privilege, reduce login friction and measure both outcomes as one programme, not two separate efforts.
From our research library:
- Across one million observed logins, 1 in 4 were password-based rather than SSO, 2 in 5 were not protected by MFA and 1 in 5 used a weak, breached or reused password.
What this signals
Access friction and over-privilege now reinforce each other in critical industries. When frontline workers face slow authentication, they create informal access patterns that security teams must later govern. That makes identity design a frontline operational control, not a back-office policy exercise.
Passwordless methods matter because they remove the conditions that make insecure shortcuts feel acceptable. In shift-based environments, the value is not simply faster sign-in. It is fewer opportunities for shared credentials, open sessions and repeated authentication fatigue.
Third-party access has to be treated as part of the same workflow problem. If vendor entitlements are provisioned manually and revoked late, the attack surface grows even when employee identity controls improve. Practitioners should evaluate both together.
For practitioners
- Reduce frontline login friction Replace repeated password entry with methods that fit shared workstations, shift handoffs and mobile use so users do not revert to insecure shortcuts.
- Re-baseline vendor entitlement Review third-party access against current business need, remove standing access that no longer maps to an active support task and require explicit revocation.
- Design for shared-device reality Account for clinicians, operators and responders who move between stations, devices and locations so the authentication flow does not depend on a private endpoint.
- Use passwordless methods where work is time-sensitive Prioritise device-bound passkeys, tap-and-go badges or biometrics in environments where repeated login friction is causing credential sharing or session leakage.
- Measure access workarounds as risk signals Track session persistence, shared account usage and login failure rates together so operational friction is visible before it becomes a security incident.
Key takeaways
- Inefficient access in critical industries is not just inconvenient. It creates the conditions for shared credentials, open sessions and broader exposure to ransomware and third-party compromise.
- The article ties the problem to concrete operational evidence, including a 9% rise in ransomware attacks on U.S. critical infrastructure, 13 minutes of clinician login time per shift and a 47% third-party breach rate.
- Security teams should align authentication and vendor access with frontline workflows, because friction and over-privilege are the same governance problem expressed in different ways.

Key terms
- Frontline Identity: Identity patterns used by workers who do not sit at a dedicated computer and may not have a personal phone or company email during the shift. These environments typically require shared-device support, deviceless interaction, and tighter lifecycle design than office-based identity programmes.
- Access Friction: Access friction is the delay, inconsistency, or effort a person experiences when trying to reach a system or task. It becomes a governance issue when it is high enough to encourage shortcuts, exceptions, or support-heavy workarounds that weaken the intended control model.
- Third-Party Access: Third-party access is access granted to vendors, contractors, or support partners who are not direct employees of the organisation. It is higher risk than internal access because accountability, device assurance, and access duration are harder to control, so it usually requires tighter time limits and stronger auditability.
- Passwordless Authentication: An authentication approach that removes passwords and uses a device-bound cryptographic key plus local user verification. It reduces phishing and replay risk, but it only improves assurance when enrollment, recovery, and revocation are tightly governed.
