Zscaler Hosts a Defining Moment in Enterprise Security in Prague
Singapore, 17 July 2025 — From June 16–18, 2025, the historic city of Prague played host to Zenith Live 2025, Zscaler’s flagship summit, where the future of cloud security took centre stage. Held at the Prague Congress Centre, this year’s theme, “Where Zero Trust Meets AI,” captured the spirit of an industry in motion, driven by transformation, collaboration, and the urgent need for cyber resilience.
The event brought together CIOs, CISOs, CFOs, and digital leaders from around the globe, positioning Zero Trust and AI as the bedrock of modern, agile, and secure enterprise infrastructure. As organisations across sectors accelerate digitisation, Zenith Live emerged not just as a tech conference but as a strategic gathering where security meets innovation and where business strategy meets technological ambition.
“Zero Trust Is That Foundation” – Jay Chaudhry, Zscaler CEO
In a powerful Day 1 keynote, Jay Chaudhry, CEO and Founder of Zscaler, delivered a compelling call to action. Reflecting the rapid pace of digital change, Chaudhry urged business leaders to rethink their organisations’ architectural foundations.
“Digital transformation without security is like building a skyscraper without a foundation. Zero Trust is that foundation.”
Chaudhry underscored that Zero Trust is not merely a cybersecurity concept—it’s an operational and economic enabler. Enterprises today are borderless, data-centric, and cloud-driven. Traditional firewalls and VPNs can no longer support the fluidity of hybrid work or the scale of global transactions.
“Zero Trust isn’t a security tool. It’s a business enabler.”
In an age where risk equals cost, Zscaler’s Zero Trust Exchange is increasingly viewed as infrastructure that enhances agility and improves ROI—particularly for finance leaders seeking cost-optimised growth in a complex landscape.
Day 2: Scaling Security at AI Speed – Deepen Desai’s Take on Cyber Defence
In the second day’s keynote, Deepen Desai, Zscaler’s Chief Security Officer, addressed the rising sophistication of cyber threats, particularly those powered by generative AI. From automated phishing tools to AI-enhanced malware, the risks have escalated—and security teams must match that pace with equal intelligence.
“Adversaries are scaling faster than ever—and so must our defences.”
Desai outlined how Zscaler is operating AI across its global cloud infrastructure, enabling rapid detection, proactive threat mitigation, and seamless integration with user workflows. Real-time machine learning, which adapts and evolves with every incident, now benefits the company’s inline inspection model, which processes over 500 trillion signals daily.
This was more than just a technical update; it served as a blueprint for maintaining a competitive edge against attackers. For CFOs, the message was clear: cyber resilience is a business imperative, and AI is no longer a futuristic experiment—it’s an essential layer of security architecture.
Innovations of Secure AI: “Guardrails, Not Roadblocks”
Perhaps one of the most insightful theatre keynotes was led by Phil Tee, EVP and Head of AI Innovations at Zscaler, titled “Innovations of Secure AI.” Phil Tee, a serial entrepreneur and pioneer in AIOps, demonstrated the effective and secure use of AI.
“We’re enabling organisations to adopt AI with guardrails—not roadblocks.”
He revealed innovations that safeguard sensitive data in AI workflows, including:
- Privacy-preserving data routing
- Enhanced prompt classification
- Autonomous segmentation to enforce policy without manual intervention
Tee’s approach demystified the complexity of AI adoption. Zscaler’s latest advancements were designed with the understanding that businesses want to move fast—but not at the expense of data control, compliance, or reputational integrity.
Reimagining Cybersecurity: A Platform, Not Just a Product
Throughout Zenith Live, it became evident that Zscaler isn’t selling products—it’s enabling a paradigm shift. Attendees explored real-world applications across sectors, including banking, transportation, healthcare, and the public sector. From Zero Trust Branch infrastructure to Zscaler Cellular—a SIM-powered endpoint protection for IoT—each solution reflected the same promise.
Security that Scales with The Business
CFOs, in particular, responded to Zscaler’s Risk360 platform for cyber quantification, which is now influencing cyber insurance premiums and streamlining compliance with global standards. In a world where finance leaders must account for digital exposure, tools like these bridge cybersecurity and financial forecasting in meaningful ways.
Final Reflections: Strategy, Not Just Security
Zenith Live 2025 did more than showcase technology—it reframed cybersecurity as a growth enabler. The convergence of Zero Trust and AI is not a matter of if, but when. In Prague, we witnessed how this convergence is already reshaping the enterprise landscape.
From Jay Chaudhry’s vision to Deepen Desai’s foresight and Phil Tee’s innovations, one message echoed across every room, every session, and every strategy discussion:
Resilience is not an accident. It is architected.
As businesses chart a course through AI disruption, regulatory uncertainty, and growing cyber complexity, Zscaler is proving to be a partner that delivers clarity, confidence, and capability.
