How PIAM Supports Zero Trust Security in Healthcare Facilities

Introduction: Zero Trust Security—A New Standard for Healthcare

In an era of rising cyber threats, data breaches, and physical security incidents, healthcare organizations are under growing pressure to protect their sensitive environments. Healthcare facilities house vast amounts of Protected Health Information (PHI), critical medical equipment, and vulnerable patient populations. A breach of security—whether physical or digital—can result in compliance violations, financial penalties, and damage to patient trust.

Traditional security models based on the “trust but verify” approach are no longer sufficient. Healthcare organizations are increasingly adopting Zero Trust security frameworks, which require continuous verification of users, devices, and systems before granting access to sensitive resources. While Zero Trust is often discussed in the context of IT security, it is equally applicable—and increasingly critical—in the physical security space.

Physical Identity and Access Management (PIAM) platforms,like Soloinsight’s CloudGate PIAM, play a vital role in implementing Zero Trust principles across healthcare facilities. By unifying identity management, automating access control, and enforcing real-time verification, PIAM provides healthcare organizations with a comprehensive solution for modern physical security challenges.

What is Zero Trust Security and Why is it Critical in Healthcare?

1. Zero Trust Defined

Zero Trust is a security framework that requires all users, devices, and applications to be continuously verified before granting access to data or resources.

2. Why Zero Trust for Healthcare?

• The healthcare sector is a top target for cybercriminals due to the value of Protected Health Information (PHI) and financial data.

• Insider threats—intentional or accidental—account for a growing percentage of breaches.

• Compliance with HIPAA, GDPR, The Joint Commission, and DEA regulations requires strict access controls and continuous policy enforcement.

Core Principles of Zero Trust in Healthcare

1. Verify Explicitly

Always verify identity, role, and context before granting access—whether digital systems or physical locations.

2. Enforce Least-Privilege Access

Grant the minimum level of access necessary, for the shortest time possible, to limit risk and reduce insider threats.

3. Assume Breach

Continuously monitor for anomalous behavior and unauthorized activity, with proactive threat mitigation strategies.

How PIAM Supports Zero Trust Security in Healthcare

Soloinsight’s CloudGate PIAM operationalizes Zero Trust principles by providing centralized control, automated identity governance, and real-time monitoring of physical access across healthcare facilities.

1. Continuous Identity Verification for Physical Access

PIAM platforms ensure that every access request is verified in real time, regardless of whether the user is on the premises or accessing a secure zone:

• Multi-factor authentication (MFA) combines something the user has (mobile credential), something they are (biometric), and something they know (PIN).

• Role-based policies and dynamic risk scoring inform access decisions, factoring in time of day, location, and real-time threat intelligence.

• Access rights are continuously validated, ensuring only authorized users enter critical areas like ICUs, pharmacies, and data centers.

Example: a trauma center using CloudGate PIAM enforces biometric verification plus mobile credential authentication for entry into surgical suites, ensuring no single point of failure in identity validation.

2. Role-Based and Attribute-Based Access Control (RBAC and ABAC)

PIAM supports Zero Trust’s least privilege access principle by enforcing Role-Based Access Control (RBAC) and Attribute-Based Access Control (ABAC):

• Staff are granted access only to the areas and systems needed to perform their duties—no more, no less.

• Access decisions are context-aware, using attributes like location, clearance level, and work schedules to enforce dynamic controls.

• Temporary access is provisioned for contractors or visitors, with automated expiration to prevent privilege creep.

Example: A psychiatric hospital using CloudGate PIAM reported a 50% reduction in unauthorized area access by enforcing strict least privilege policies through RBAC.

3. Real-Time Access Monitoring and Threat Detection

Zero Trust assumes a breach may already be happening, so continuous monitoring is key:

• PIAM provides real-time monitoring of access events, giving security teams visibility into who is accessing what areas and when.

• AI-powered analytics identify anomalous behavior, such as an individual attempting to access restricted areas outside of approved hours.

• Automated alerts enable rapid response, helping mitigate threats before they escalate.

Example: A healthcare network implementing CloudGate PIAM reduced response time to potential security threats by 60%, increasing overall facility safety.

4. Integration of Physical and IT Security

Zero Trust requires an integrated security architecture that includes both digital and physical environments:

• PIAM synchronizes with Active Directory, HRIS, and IAM systems, ensuring identity consistency across all domains.

• Physical access events are correlated with IT system access logs, allowing for comprehensive security audits and investigations.

• Access decisions reflect the full digital-physical risk picture, enabling holistic enforcement of Zero Trust policies.

Example: an employee’s access to a patient records server can be denied automatically if their physical badge has not been validated at an authorized entry point within a defined time frame.

5. Automated Identity Lifecycle Management

In Zero Trust security models, identity management must be dynamic and adaptive:

• Onboarding, role changes, and offboarding are managed in real time.

• Access is revoked automatically when staff roles change or when an employee leaves, eliminating gaps in enforcement.

• Temporary access privileges for contractors, vendors, or visitors expire without

manual intervention, ensuring consistent adherence to least privilege policies.

Example: A healthcare provider using CloudGate PIAM cut offboarding time by 70%, reducing lingering credential risks.

6. Unified Physical and Digital Identity Governance

PIAM integrates with Identity and Access Management (IAM) systems, aligning physical and logical access:

• Unified policies govern both physical facility access and IT system logins, providing a holistic security approach.

• Cross-domain anomaly detection correlates physical and digital events—for example, flagging if a clinician accesses an EHR system remotely without having badged into the facility.

This Zero Trust integration ensures consistent identity governance and supports Zero Trust Network Access (ZTNA) initiatives.

Use Cases: PIAM Enabling Zero Trust in Healthcare Facilities

1. Securing Data Centers and EHR Systems

• IT staff must pass biometric verification and MFA to access server rooms housing patient data.

• PIAM continuously monitors access patterns and flags off-hours access attempts for review.

2. Controlling Access to High-Risk Areas

• Operating rooms, ICUs, and psychiatric wards are protected by multi-layered authentication and real-time monitoring.

• PIAM enforces role-based access, ensuring only staff assigned to those areas can enter.

3. Managing Third-Party and Contractor Access

• Contractors are issued temporary credentials, with strict expiration policies.

PIAM ensures that vendors only access designated work areas, with no lateral movement permitted

Business Benefits of Implementing PIAM for Zero Trust Security
