The role of the healthcare CIO looks nothing like it did a decade ago. Running the EHR, keeping infrastructure online, and managing vendor contracts are still table stakes, but they’re no longer the whole story. Today’s healthcare CIOs are being asked to do something far bigger: lead enterprise-wide transformation.

It’s 3 AM. API latency just spiked from 200ms to 2s. Alerts are firing, and users are frustrated. You SSH into the first server: top, free -h, iostat — nothing unusual. On to the next host. And the next. That’s how most of us learned to debug. The tools worked, and we got good at using them. But as infrastructure became distributed and dynamic, this approach started to break down. Modern monitoring needs more than SSH and top. It needs unified telemetry.

A SaaS team once spotted their first breach not in a SIEM dashboard, but in their AWS bill. Their compute costs spiked by 400% overnight. Turns out, an attacker had spun up dozens of high-powered instances for crypto mining. Logs eventually confirmed the intrusion, but the cost anomaly was the first signal that something was wrong. This incident isn’t unusual. Cloud costs often reflect consumption, but they can also reflect compromise.

Man-in-the-Middle (MITM) attacks remain one of the most dangerous cybersecurity threats. In these attacks, hackers secretly intercept and sometimes alter communication between two parties. Without proper encryption, sensitive data such as passwords, credit card details, and personal information becomes exposed. SSL/TLS certificates encrypt this communication, preventing unauthorized access. However, certificates can expire, become misconfigured, or become compromised, creating security gaps.
