Introduction
A single ransomware attack was all it took to bring an entire medical diagnostics network to a halt. A major healthcare leader, responsible for processing 75 million clinical exams annually, faced a severe ransomware attack that brought operations to a standstill for seven days. Cybercriminals exploited weaknesses in privileged access controls, encrypting critical systems and preventing the company from delivering essential diagnostic services. With hospitals, laboratories, and outpatient clinics relying on its infrastructure, the organization had no choice but to act fast.
For years, the company had been expanding through acquisition. Without a centralized security framework, privileged accounts were everywhere, creating blind spots. The ransomware attack was a turning point. The company needed a solution to regain control, prevent future breaches, and protect its ability to provide life-saving diagnostics.
Major Challenges with Security and Compliance
The attack revealed the extent of the security gaps. More than 1,500 unmanaged servers, 2,000 devices, and 500 databases were left vulnerable, giving attackers unrestricted access to sensitive systems. Privileged credentials were embedded in configuration files and hardcoded into scripts, making them easy to steal. Without centralized credential management, cybercriminals were able to move laterally through the network undetected, escalating privileges and locking down essential medical systems.
Compliance had also become a growing challenge. The company needed full visibility into privileged access, yet real-time monitoring and logging were inconsistent across different environments. Security teams struggled to track who accessed what systems and when, making it nearly impossible to provide accurate audit reports. The attack was no longer just an IT issue, but a direct threat to business continuity, patient care, and regulatory compliance.
A ransomware attack shut down operations for 7 full days and exposed thousands of unprotected credentials and critical systems
Transformative Solutions with senhasegura
The company needed an immediate and decisive response. In just three days, senhasegura was deployed on a 3-node cloud-based high availability and disaster recovery architecture, restoring security and creating a failover system to prevent future downtime. Within six hours, privileged credentials were redefined, and all 1,500 servers, 100 network assets, and workstations were scanned, discovered, and onboarded into the system.
Security was reinforced at every level. Privileged session monitoring was implemented to track and record all administrative actions in real time. Multi-factor authentication (MFA) was enforced, preventing unauthorized users from accessing critical infrastructure. The company also integrated SIEM and user behavior analytics, allowing security teams to instantly detect unusual activity and block potential threats before they could escalate.
With senhasegura, the company no longer had to rely on fragmented security policies across different locations. Privileged access was now controlled through a single, centralized platform, giving the IT team full oversight of every privileged action across the entire organization.
Witnessing the Transformation
The results were immediate. 100% of privileged credentials were secured and centrally managed, eliminating the vulnerabilities that had enabled the ransomware attack. All privileged access from outside the PAM solution was blocked, ensuring that only verified users could access critical systems. Instead of reacting to security threats, the IT team could now proactively monitor, detect, and prevent suspicious activity in real time.
senhasegura restored security in just three days, securing 100% of privileged credentials and stopping unauthorized access.
Embracing the Future
This medical diagnostics company is no longer scrambling to recover from security breaches—it is actively preventing them. What was once a fragmented and high-risk IT environment is now a fully controlled and monitored privileged access ecosystem.
senhasegura has not only restored security but also provided a scalable solution that grows with the organization. As the company continues to expand, each new facility is seamlessly integrated, ensuring consistent security across every hospital, laboratory, and diagnostic center. Privileged access is no longer a weakness. It’s now a strategic advantage that protects operations, maintains compliance, and secures the future of medical diagnostics.
