Work has fundamentally shifted from applications and networks to the browser itself. Today, the browser is where employees access SaaS, collaborate and interact with AI, making it the true operating system of modern work. But as work moved into the browser, security controls didn’t follow. Within the last year, 95% of organizations have reported a security incident originating in the browser, as attackers shift their focus from hardened networks to exposed web sessions.
Legacy security tools were built for defined perimeters and managed endpoints, not for AI-powered workflows running across encrypted traffic, SaaS applications and unmanaged devices. As work increasingly happens inside the browser, many of the traditional controls that organizations have relied on simply no longer apply.
The result is a growing visibility, governance and control gap at the exact point where work happens. As AI, SaaS and browser-based workflows become the default, enterprise security leaders are forced to confront a new set of risks and questions they can no longer ignore.
Here are the five questions keeping Chief Experience Officers (CxOs) up at night that Prisma® Browser™ helps address.
For organizations, GenAI is a double-edged sword. It drives incredible speed, but it introduces massive shadow AI risks, which will only increase as 12 thousand AI apps are expected to be in use by 2030. The danger usually isn't malicious intent; it’s the hundreds of microdecisions employees make daily. In the rush to be productive, employees may unknowingly submit proprietary code, model parameters, sensitive customer data or other confidential information into unsanctioned GenAI prompts, exposing the organization to significant risk.
For CxOs, this raises the prospect of intellectual property loss from everyday AI use that remains largely invisible to security teams. Legacy network tools are unable to notice these specific last-mile actions, so security teams often resort to bluntly blocking GenAI apps entirely.
As work moves into the browser, the network perimeter has quietly shifted from the office firewall to an employee’s kitchen counter. Unmanaged personal devices are an invisible risk, whether it’s a contractor accessing a sensitive application, an employee checking email after hours from a personal desktop, or a user connecting from a mobile device outside corporate oversight. The statistics are alarming: 92% of successful ransomware attacks originate from unmanaged devices. These devices often run gaming apps or risky extensions that fall completely outside of corporate control. For CxOs, this means a single infected personal device can become a direct path to ransomware, data loss and other threats.
Legacy tools cannot see what happens within the browser. Organizations increasingly face new threats that evade network security, such as reassembly attacks, where malware is chopped into innocent-looking fragments to bypass firewalls, only to reassemble inside the browser’s memory. At the same time, malicious browser extensions can abuse trusted permissions to steal credentials, capture sessions or exfiltrate data without triggering traditional controls. Combined with AI-driven spear phishing that creates clean, unique typo-free lures, attackers can hijack identities and exfiltrate data while your network logs remain perfectly clean. For CxOs, this creates a dangerous blind spot where breaches can unfold inside trusted web sessions without detection, until sensitive data has already been compromised.
The world is shifting from the tools you chat with to the tools that act on your behalf, and that’s where agentic browsers come into the picture. This creates two massive risks:
Compounding this problem is the inability to distinguish between actions taken by a human vs. an agent. For CxOs, this introduces an entirely new governance challenge: Ensuring AI systems cannot take unauthorized actions, access sensitive systems, or operate without clear accountability and oversight.
In a browser-first world, data leakage rarely looks like a breach; it just looks like everyday work. Employees move data between SaaS applications or share content across personal and corporate environments in the name of productivity. The problem for CxOs is that these actions happen inside trusted sessions, often beyond the reach of traditional enterprise security controls. As AI accelerates workflows and data moves faster than policies can keep up, accidental exposure becomes a board-level risk, carrying regulatory, financial and reputational consequences that organizations may not detect until it is too late.
This is how Prisma Browser helps answer these questions, addressing these challenges by securing the last mile where work, data and AI interactions actually happen.
1. Control AI Use With Confidence: Stop saying “no” to innovation. Prisma Browser enables safe AI usage with surgical precision. Instead of disrupting workflows, it enforces granular content and context-aware policies, such as blocking file uploads to public LLMs while allowing uploads to your private internal sandbox. With Enterprise DLP, Prisma Browser identifies sensitive data and prevents data leaks into GenAI prompts before data leaves the enterprise environment, while providing detailed auditing and visibility to support compliance requirements.
2. Secure Hybrid Work: Prisma Browser creates a secure isolated workspace on any device, enabling secure work from any location, any application and any device. For IT and security teams, this eliminates the cost and friction of VDI and shipping laptops and enables zero-trust access for personal devices and for independent contractors in minutes. By embedding enterprise-grade DLP directly into a familiar interface and leveraging AI-driven security, it prevents data exfiltration and mitigates even the most advanced web threats.
3. Prevent Evasive Threats in Real-Time: Prisma Browser continuously scans every page in real-time before it loads in the browser, catching the evasive threats that legacy tools miss. It identifies malware hiding in encrypted traffic, malicious scripts and web-based threats, such as AI-powered spear phishing attacks. The browser protects against malicious extensions by continuously monitoring permissions, updates and usage, while blocking malicious or risky extensions automatically. With this visibility, security teams finally regain control of what was once a blind spot in the browser ecosystem.
4. Govern Agentic AI: Prisma Browser brings an AI assistant with agentic browsing capabilities into the modern workspace while extending all AI-powered last-mile security controls to agent-driven actions. It applies DLP and identity controls to distinguish between human and AI activity, enforce inline governance, while enabling step-up MFA and just-in-time permissions for sensitive actions. Integrated with Prisma AIRS™ for topic guardrails, the browser defends against prompt-injection attempts and supports a flexible BYO-LLM model, so organizations can securely govern agentic workflows while maintaining full control.
5. Protect Customer Data: Prisma Browser eliminates the visibility gaps that plague traditional security by providing insights into every user interaction across all web, SaaS and GenAI applications in use, including unsanctioned applications. By securing the last mile, the critical point where data is rendered and manipulated, the browser applies granular controls that stop leaks in real time. From masking sensitive, personally identifiable information (PII) and blocking unauthorized uploads to restricting copy-paste and screenshots, Prisma Browser enforces strict controls over how data is handled. This ensures your proprietary data stays within corporate boundaries, even on unmanaged devices, and reduces the risk of accidental data loss.
Shift the browser from a liability you manage to a high-performance workspace you trust.
Prisma Browser is designed to let you embrace cloud applications and AI with confidence. It’s time to protect data, govern AI use and stop threats where work happens.
