Sentinel Gives an Identity Security Booster Shot to a Midwest Hospital

healthcare4

Customer

Over its 100+ year history, the customer has taken great pride in delivering top-quality care to every one of its patients throughout the Midwest. Frequently recognized as one of the best hospitals in the country, their large campus includes more than 300 patient beds as well as doctor offices, outpatient services, and a cancer care center.

Environment

Sentinel has worked with the customer for nearly 20 years, upgrading a vast majority of their environment, including voice, wireless, data storage, backup, servers, network switches, and security. Monitoring, maintenance, and technical support for the customer were handled through Sentinel’s managed services, ACTS, and Security Operations Center (SOC) offerings.

Challenge

The customer was interested in implementing a robust privileged access management system to enhance the control and protection of their user identities. They collaborated closely with their partners at Sentinel to find a solution capable of integrating with their existing identity providers that could also support session recording, host scaling, Kerberos authentication, private-only deployments, as well as interactive access protocols such as Secure Shell (SSH) and Remote Desktop Protocol (RDP). It was also essential that any solution would ensure secure and compliant access to privileged sessions while meeting regulatory requirements.

Solution

The Sentinel team began by conducting a thorough identity access security analysis of the customer’s critical systems, configurations, and policies.

  • Reviewed existing policies for privileged interactive session access and identified up to one identity provider (e.g., Active Directory Domain Services or Entra ID tenants).
  • Reviewed configuration of interactive access protocols and support for authentication of access requirement combinations.
  • Assessed business enablement requirements and access controls to prevent out-of-policy privileged sessions.

It was determined that Microsoft Azure Bastion would be the best solution to further strengthen the customer’s entitlement management practice. Sentinel took the following actions:

  • Created Azure Resource Groups, Virtual Networks (VNets), and subnets.
  • Configured Azure Bastion deployment, including host scaling, Kerberos authentication, IP address connections, session recording, and private-only deployments.
  • Set up Azure Role-Based Access Control (RBAC) rules and local system firewall restrictions using configuration profiles.
  • Implemented Entra Privileged Identity Management eligible assignments and demonstrated access reviews.

Results

Sentinel’s assessment and deployment of Azure Bastion successfully transformed the customer’s privileged access management approach for stronger identity protection, tighter access controls, and improved operational efficiency. Expert configuration also ensured hospital staff could securely connect to critical systems while maintaining full compliance with healthcare security and auditing requirements.

Sentinel’s customized and detail-oriented approach also helped the customer streamline governance and accountability. The hospital now benefits from stricter enforcement of least‑privilege access and improved visibility into role-based user activity. The solution eliminated gaps and made it easier for internal teams to spot unusual user behavior or other potential indicators of compromise.
