Weekly Inspired Arora Opinion & Analysis

This weekly column has been created based on a deep analysis of how Nikesh Arora, CEO of Palo Alto Networks, strategizes in the cybersecurity space, drawing inspiration from his leadership style, forward-thinking approach, and innovative insights. While not an exact representation, the column embodies key elements of his strategic mindset and vision for the future of cybersecurity.

ā€”

Last week, two headlines told the same story: the past is our biggest vulnerability.

First, Oracle Healthā€™s legacy Cerner systemsā€”those not yet migrated to the cloudā€”were breached, leaking sensitive patient data across multiple U.S. hospitals. The same week, Advanced Computer Software Group was fined Ā£3 million for a 2022 ransomware attack on NHS services, triggered by preventable security failures.

Thereā€™s a clear signal here: legacy infrastructure isnā€™t a technical inconvenienceā€”itā€™s a liability. In todayā€™s threat environment, modernization isnā€™t optional. Itā€™s risk mitigation.

Attackers donā€™t differentiate between healthcare, finance, or governmentā€”they pursue weak points, and legacy systems are inherently weak. Their architectures predate todayā€™s threat models. They lack telemetry, access control granularity, and often even basic encryption.

Too many organizations cling to legacy environments under the banner of "business continuity." But when continuity comes at the expense of resilience, it becomes a false economy. Security gaps in deferred migrations create openings adversaries are actively exploiting.

Cloud migration alone wonā€™t solve this. But the discipline that comes with re-architecting for the cloudā€”zero-trust posture, least privilege access, continuous integration of threat intelligenceā€”forces a modern security approach. Thatā€™s the real value.

Meanwhile, Oracleā€™s second headlineā€”customers confirming the validity of leaked SSO cloud data despite corporate denialsā€”reinforces a parallel lesson: transparency and speed matter more than messaging. If users find out the truth before your CISO does, you've already lost.

For CISOs, the guidance is simple:

  • Inventory and audit all legacy systemsā€”not just for vulnerabilities, but for operational exposure.

  • Accelerate cloud migration not for efficiency, but to force a modern security posture.

  • Verify vendor claims and enforce zero-trust policies even in cloud-native environments.

  • Run incident response drills assuming your weakest system will be hitā€”not your most valuable.

The threat landscape is evolving faster than regulatory frameworks can keep up. We canā€™t afford to anchor ourselves to architectures built for a different era. If your infrastructure strategy includes the word ā€œwait,ā€ rethink it.

In security, technical debt has a way of becoming breach debt. And no amount of insurance, PR, or legal firepower can pay off that balance once trust is lost.

Until next week,
