8 terms

agentic ai technical

"the industry's most secure browser built for the Agentic AI era."

Agentic AI refers to computer systems that can make their own decisions and take actions without needing someone to tell them what to do each time. It's like giving a robot a degree of independence to solve problems or achieve goals on its own, which matters because it could change how we work and interact with technology in everyday life.

autonomous agents technical

"utilizing autonomous agents that act on their behalf, Prisma Browser converts"

Autonomous agents are software programs that carry out tasks and make decisions on their own using predefined rules and data, often improving over time by learning from outcomes; think of them as trusted employees that act without being constantly supervised. Investors care because these agents can boost productivity and cut costs, enable new services or revenue streams, and change competitive dynamics, while also introducing operational, legal and oversight risks that can affect a company's value.

llm technical

"Enables organizations to leverage the LLM of their choice across all models"

A large language model (LLM) is an advanced computer system trained on vast amounts of written text to understand and generate human-like language, similar to a very fast, well-read assistant that can summarize documents, draft messages, or answer questions. Investors care because LLMs can speed up research, automate customer support, and reduce costs, while also creating new product opportunities and risks around accuracy, bias, and regulatory oversight that can affect a company’s performance.

prompt injection attacks technical

"blocks prompt injection attacks—including malicious instructions hidden within websites"

Prompt injection attacks are attempts to trick an AI system by feeding it malicious or misleading instructions hidden inside user inputs, causing the AI to ignore its normal safeguards or reveal sensitive information. For investors, this matters because compromised AI tools can produce wrong research, leak confidential data, or trigger faulty trading signals, similar to an assistant being misled by a deceptive instruction and making costly mistakes.

shadow ai agents technical

"risks unique to autonomous AI has emerged, such as shadow AI agents, prompt"

Shadow AI agents are unofficial or unsupervised automated software tools that employees use to perform tasks—like drafting messages, analyzing data, or making routine decisions—without formal approval or oversight from IT or compliance teams. They matter to investors because these “ghost helpers” can speed work but also create hidden risks to data security, regulatory compliance, and financial controls, which can affect a company’s costs, reputation, and legal exposure.

sase technical

"Prisma SASE, the most comprehensive SASE solution built for the agentic AI era."

SASE, or Secure Access Service Edge, is a modern technology that combines network security and access management into a single, cloud-based service. It ensures that users can safely connect to company resources from anywhere, much like having a secure, virtual gatekeeper that protects digital information. For investors, SASE matters because it reflects how organizations are adopting advanced security measures to support flexible, remote work environments and protect valuable data.

zero trust technical

"Prisma SASE delivers Universal Zero Trust, providing consistent protection"

Zero trust is a security approach that assumes no one, whether inside or outside an organization, should be automatically trusted. Instead, every access request is carefully verified before being granted, much like checking ID at every door rather than trusting someone just because they are known. For investors, it emphasizes the importance of protecting digital assets and data from potential breaches, reducing overall risk.

saas technical

"protect information across endpoints, network, and SaaS."

SaaS, or Software as a Service, is a way of delivering computer programs over the internet, allowing users to access and use them through a web browser without needing to install or maintain the software themselves. For investors, it highlights a business model where companies generate recurring revenue by providing ongoing access to their software, often leading to predictable income and growth potential.

Prisma SASE enhancements secure AI-driven work across the entire modern enterprise 

SANTA CLARA, Calif., March 23, 2026 /PRNewswire/ -- Palo Alto Networks (NASDAQ: PANW), the global cybersecurity leader, today unveiled a major evolution of Prisma Browser, introducing the industry's most secure browser built for the Agentic AI era. As employees shift from merely using AI as a tool to now utilizing autonomous agents that act on their behalf, Prisma Browser converts the web into a secure AI-driven workspace. Users can now unlock new levels of productivity with Agentic AI, without compromising security.

Today, the browser is the primary engine of modern work and where users spend 85% of their workday. However, the browser's role is rapidly expanding beyond a simple window to the web and is now the central hub for agentic AI interactions. While this shift unlocks unprecedented efficiency, a new class of sophisticated risks unique to autonomous AI has emerged, such as shadow AI agents, prompt injection attacks and agent hijacking. Prisma Browser paves the way for this new era of work by providing agentic capabilities in combination with a secure foundation to protect these autonomous workflows.

Anand Oswal, Executive Vice President of AI & Network Security, Palo Alto Networks
"Organizations are unleashing a new workforce of agents, however, you cannot give autonomy without security. By embedding AI-powered data protection and securing AI interactions directly in the browser, leaders can now confidently greenlight strategic AI initiatives that were previously stalled. Prisma Browser isn't just securing an interface, it's securing a new way of work."

Prisma Browser introduces key innovations that bring secure agentic AI to end users by:

• Powering the Agentic Workspace: Enables organizations to leverage the LLM of their choice across all models and platforms. Prisma Browser allows teams to utilize the most effective AI tools for any specific task, maximizing productivity and accelerating autonomous workflows.
• Securing AI Interactions: Automatically discovers user AI activity and enforces content-aware boundaries to keep agents within their intended scope. Prisma Browser prevents sensitive data from leaking to unmanaged or public AI tools during automated tasks.
• Preventing Agent Hijacking: Identifies and blocks prompt injection attacks—including malicious instructions hidden within websites designed to hijack AI agents—keeping automated workflows on track and preventing agents from being manipulated into unauthorized actions.
• Enabling Global Compliance: Provides real-time distinction between human actions and automated AI tasks. By assessing the intentions of both human and non-human identities, Prisma Browser enables total accountability and compliance with evolving global AI regulations.

Jonathan Jaffe, Chief Information Security Officer, Lemonade
"The browser has evolved to deal with a whole new landscape of threats with AI threats, like prompt injection or the use of AI extensions that are unsafe. The browser will continue to be the single control point as agents end up doing things on behalf of the user, but through the browser. So I see the browser as being the dominant control point for protecting employees against bad actions. As we allow people to experiment with agents that use the browser to run tasks, we feel more comfortable doing that with Prisma Browser."

The Industry's Most Comprehensive SASE Solution for the Agentic AI Era
AI-driven productivity starts in the browser but must be secured across the entire enterprise. Prisma Browser's evolution is just one of the critical innovations made to Prisma SASE, the most comprehensive SASE solution built for the agentic AI era. Powered by Precision AI, Prisma SASE delivers Universal Zero Trust, providing consistent protection and unmatched performance wherever work happens.
