The work has essentially moved from applications and networks to the browser itself. The browser is now the place for employees to access SaaS and collaborate and interact with AI, making it the true operating system of modern work. However, once work moved to the browser, security controls could no longer keep up. Over the past year, 95% of organizations have reported security incidents caused by browsers as attackers shift their focus from hardened networks to exposed web sessions.
Traditional security tools were built for defined boundaries and managed endpoints, rather than AI-powered workflows that run across encrypted traffic, SaaS applications, and unmanaged devices. As more and more work is done within the browser, many of the traditional controls that organizations relied on are no longer applicable.
The result is increased visibility, governance, and control gaps at the very point the work is being done. As AI, SaaS, and browser-based workflows become the default, enterprise security leaders are forced to face new risks and questions that can no longer be ignored.
Here are the five questions Prisma keeps chief experience officers (CxOs) up at night.® Browser™ helps with addressing.
1. Are employees exposing trade secrets to AI?
For organizations, GenAI is a double-edged sword. This provides incredible speed, but introduces massive shadow AI risk. With 12,000 AI apps expected to be in use by 2030, this risk will further increase. Danger is usually not malicious. It’s the hundreds of small decisions employees make every day. In the rush to be productive, employees can unknowingly submit proprietary code, model parameters, sensitive customer data, and other sensitive information to unauthorized GenAI prompts, putting your organization at significant risk.
For CxOs, this increases the potential for loss of intellectual property due to routine AI usage that goes largely unnoticed by security teams. Traditional network tools cannot recognize these specific last-mile actions, so security teams often resort to blocking GenAI apps entirely.
2. Can a hacker break into an employee’s personal device?
As work moved to the browser, the network perimeter quietly migrated from the office firewall to the employee’s kitchen counter. Unmanaged personal devices are an invisible risk, whether it’s a contractor accessing sensitive applications, an employee checking email from a personal desktop during off-duty hours, or a user connecting from a mobile device outside of corporate oversight. The statistics are staggering: 92% of successful ransomware attacks originate from unmanaged devices. These devices often run gaming apps and dangerous extensions that are completely outside the company’s control. For executives, this means a single infected personal device can become a direct path to ransomware, data loss, and other threats.
3. Are attacks hiding in your browser?
Traditional tools don’t allow you to see what’s happening inside your browser. Organizations increasingly face new threats that evade network security, such as reassembly attacks, where malware is chopped into harmless-looking pieces to evade firewalls and then reassembled only in the browser’s memory. At the same time, malicious browser extensions can abuse trusted permissions to steal credentials, capture sessions, and exfiltrate data without triggering traditional controls. Combined with AI-driven spear phishing that creates unique clean, typo-free lures, attackers can take over identities and steal data while keeping network logs completely clean. This creates a dangerous blind spot for executives, allowing a breach to unfold undetected within a trusted web session until sensitive data has already been compromised.
4. Is it possible for my AI browser to become fraudulent?
The world is moving from tools that chat to tools that act on your behalf, and that’s where agent browsers come in. This poses two major risks:
Compounding this problem is the inability to distinguish between actions taken by humans and actions taken by agents. This poses entirely new governance challenges for executives. It is about ensuring that AI systems cannot perform unauthorized actions, access sensitive systems, or operate without clear accountability or oversight.
5. Can users compromise customer data?
In a browser-first world, data breaches rarely look like breaches. It looks like just a daily job. Employees move data between SaaS applications and share content between personal and corporate environments in the name of productivity. The problem for executives is that these actions occur within trusted sessions and are often beyond the scope of traditional corporate security controls. As AI accelerates workflows and data moves faster than policies can keep up, accidental exposure becomes a board-level risk with regulatory, financial, and reputational implications that organizations may not be able to detect until it’s too late.
Browse bravely and take control with Prisma Browser
In this way, Prisma Browser answers these questions and addresses these challenges by securing the last mile, where work, data, and AI actually interact.
1. Control your use of AI with confidence: Stop saying no to innovation. Prisma Browser enables the safe use of AI with surgical precision. Rather than disrupting workflows, enforce fine-grained content and context-aware policies, such as blocking file uploads to public LLMs while allowing uploads to a private internal sandbox. With Enterprise DLP, Prisma Browser identifies sensitive data, prevents data leakage to GenAI prompts before it leaves the enterprise environment, and provides deep auditing and visibility to support compliance requirements.
2. Safe hybrid work: Prisma Browser creates securely isolated workspaces on any device, allowing you to work securely from anywhere, in any app, and on any device. For IT and security teams, this eliminates the cost and hassle of VDI and laptop shipping, and enables zero-trust access to personal devices and independent contractors in minutes. Prevent data leakage and mitigate even the most advanced web threats by building enterprise-grade DLP directly into your familiar interface and leveraging AI-driven security.
3. Stop evasive threats in real time: Prisma Browser continuously scans every page in real-time before it loads in your browser, catching evasive threats that traditional tools miss. Identify malware hidden in encrypted traffic, malicious scripts, AI-powered spear phishing attacks, and other web-based threats. The browser protects against malicious extensions by continuously monitoring permissions, updates, and usage, and automatically blocks malicious or dangerous extensions. With this visibility, security teams can finally take back control of what was once a blind spot in the browser ecosystem.
4. Manage agent AI: Prisma Browser brings an AI assistant with agent browsing capabilities to the modern workplace, extending AI-powered last-mile security controls to all agent-driven actions. Apply DLP and identity controls to differentiate between human and AI activity and enforce inline governance while enabling step-up MFA and just-in-time authorization for sensitive actions. Integrated with Prisma AIRS™ for topic guardrails, the browser defends against prompt injection attempts and supports a flexible BYO-LLM model, allowing organizations to securely manage agent workflows while maintaining full control.
5. Protection of customer data: Prisma Browser eliminates the visibility gaps that plague traditional security by providing insight into every user interaction across all web, SaaS, and GenAI applications in use, including unauthorized applications. By securing the last mile, the critical point where data is rendered and manipulated, browsers apply granular controls that stop leaks in real time. Prisma Browser provides strict controls on how your data is processed, from masking sensitive personal information (PII) and blocking unauthorized uploads to limiting copy-paste and screenshots. This ensures that proprietary data remains within corporate boundaries, even on unmanaged devices, reducing the risk of accidental data loss.
