From Skeptic to Secure: How a CISO Safeguarded $8.8T in 90 Days
▼ Summary
– Enterprise browsers like Island are emerging as a frontline defense against shadow AI, preventing employees from pasting sensitive data into unmanaged AI tools.
– AI is enhancing cybersecurity by improving threat detection and response, but also enabling more sophisticated phishing and deepfake attacks.
– Deepfakes and unauthorized AI use (shadow AI) are top concerns for CISOs, as they risk data exposure and compliance violations.
– Clearwater Analytics deployed Island’s enterprise browser to control AI tool usage, balancing security with employee productivity.
– The shadow AI threat is growing rapidly, with security vendors competing across four key battlegrounds: enterprise browsers, SASE/SSE platforms, traditional DLP, and specialized solutions.
Protecting $8.8 Trillion: How One CISO Tackled Shadow AI Head-On
When Sam Evans, CISO of Clearwater Analytics, walked into a board meeting in late 2023, he faced a daunting challenge, securing the firm’s $8.8 trillion in assets against the rising tide of shadow AI. Employees experimenting with unauthorized AI tools posed a serious risk, potentially exposing sensitive customer data to unvetted platforms.
Evans knew blocking AI outright wasn’t the answer. Instead, he championed a solution that balanced security with productivity, enterprise browsers. By deploying Island, a specialized browser with built-in controls, his team could prevent data leaks while still allowing employees to harness AI’s benefits.
The AI Security Paradox
AI has transformed cybersecurity into a high-stakes game of cat and mouse. Attackers leverage AI to craft hyper-realistic phishing emails, while defenders use it to detect threats faster. Evans highlighted how AI-powered security tools now analyze patterns with higher accuracy, reducing false positives and speeding up response times.
Yet, the biggest threat wasn’t external, it was internal. Employees, often unknowingly, pasted proprietary data into public AI tools, inadvertently training models with sensitive information.
From Skeptic to Believer: The Island Deployment
Evans initially doubted claims that an enterprise browser could be deployed in weeks. But Island proved him wrong. Starting with a pilot group of 200 employees, the rollout was seamless. The browser blocked unauthorized data uploads while still permitting legitimate AI queries.
When the board asked for proof, Evans showed them a simple screenshot: an attempt to paste restricted data into ChatGPT triggered an immediate policy violation alert. The board was sold.
Beyond Browsers: The Shadow AI Arms Race
The battle against shadow AI isn’t limited to browsers. Security vendors are racing to adapt:
- Enterprise Browsers (Island, Chrome Enterprise) – Control data flow at the browser level.With over 12,000 AI apps already cataloged—and growing at 5% monthly—security teams face an uphill battle. Traditional bans only push usage underground, making visibility and smart controls the real game-changers.
The Human Factor in AI Security
No tool can fully eliminate risks like deepfake scams. Evans relies on security awareness training and simple checks, like verifying unusual CEO requests, to combat social engineering.
His advice to fellow CISOs? “Don’t just block, enable.” Bringing solutions, not just restrictions, ensures security doesn’t stifle innovation.
As shadow AI continues to evolve, Evans’ approach proves that proactive adaptation, not fear, is the key to staying ahead.
