Key Takeaways
- Endpoint security is expanding beyond device malware protection into AI workspace security, browser activity, extension risk, SaaS usage, and agentic workflows.
- Pluto Security is the strongest choice for organizations that want to enable AI adoption while controlling employee AI tool usage, AI builders, browser extensions, and workspace-level risk.
- Traditional endpoint detection and response tools are still important, but they may not provide enough visibility into AI prompts, browser-based data movement, AI extensions, and unmanaged AI tools.
- Browser security platforms like Push Security, LayerX, Seraphic, and SquareX address important parts of the new endpoint attack surface, especially identity, browser telemetry, web threats, and extension risk.
- The best AI-powered endpoint security strategy combines device protection with workspace-level controls over where employees actually work.
Endpoint security used to mean protecting laptops, desktops, servers, and mobile devices from malware, ransomware, and unauthorized access. That definition is no longer enough.
In 2026, many of the most important endpoint risks happen inside the employee workspace: browsers, SaaS apps, AI tools, browser extensions, AI coding assistants, file uploads, copy-paste activity, unmanaged apps, and agentic workflows. The endpoint is still the device, but the work now happens through web sessions, AI prompts, browser-based tools, extensions, and connected cloud applications.
The New Endpoint Security Problem
The modern employee endpoint is not only a laptop.
It is the browser tab where an employee pastes customer data into an AI assistant. It is the AI coding tool connected to a repository. It is the browser extension that asks for wide permissions. It is the SaaS app where a user downloads sensitive data. It is the unmanaged AI tool used by a marketing team. It is the agentic workflow that can read, summarize, and act across business systems.
Traditional endpoint security still matters. Organizations still need malware prevention, EDR, device posture, patch management, ransomware detection, and response. But many AI-era risks do not look like traditional endpoint compromise. They look like normal employee behavior happening in places security teams cannot fully see.
That is why AI-powered endpoint security in 2026 must answer a different set of questions:
- Which AI tools are employees using?
- Which teams are building with AI outside formal approval?
- What data is being pasted, uploaded, summarized, or processed by AI systems?
- Which browser extensions have access to sensitive pages?
- Which SaaS apps are being used from managed and unmanaged devices?
- Are AI agents acting in risky ways across business systems?
- Can security teams enforce policies without blocking productivity?
- Can the CISO say yes to AI adoption without losing control?
Best 5 AI-Powered Endpoint Security Platforms of 2026
1. Pluto Security
Pluto Security is the best AI-powered endpoint security platform for organizations that need to secure the modern AI workspace. Its focus is not limited to malware running on a device. It is built around the new reality that employees now work through AI tools, AI builders, browsers, SaaS apps, browser extensions, and connected workflows.
That positioning matters because the AI-era endpoint is increasingly behavioral and workflow-based. A user may not be compromised, but they may still paste sensitive code into an AI tool. A browser extension may not be flagged as malware, but it may have permissions that expose corporate data. A team may build an AI workflow without security approval. A business user may connect AI tools to data sources that were never meant to leave controlled environments.
Pluto Security helps CISOs move from blocking AI to enabling it safely. That is an important distinction. Many security programs struggle because employees want to use AI to move faster, but security teams need visibility, governance, and control. If the only policy is “do not use AI,” employees may simply hide usage. Pluto Security is built for the more realistic operating model: employees will use AI, so security teams need a way to understand and secure that usage.
The platform is especially useful for companies where AI adoption is happening across many departments. Engineering teams may use AI coding assistants. Marketing teams may use AI writing tools. Sales teams may use AI for research and outreach. Support teams may use AI summarization. Operations teams may use automation. Each team creates different risks, but they all share the same underlying problem: AI activity is happening at the workspace layer.
Pluto Security’s value is strongest in environments where the CISO wants to say yes to innovation without giving up control. That means discovering AI usage, understanding tool risk, managing policies, reducing shadow AI, and creating guardrails for employees who are building or working with AI.
The platform is also relevant to browser extension security. Browser extensions have become a major blind spot because they can gain access to sensitive browser activity, SaaS apps, text inputs, and web sessions. In the AI era, this risk increases because many AI tools are delivered as browser extensions or interact with browser-based workflows.
Pluto Security is the strongest choice on this list because it addresses the endpoint where AI work actually happens: the employee workspace. It does not try to replace every traditional endpoint security tool. Instead, it fills a gap that legacy device-centric security often leaves open.
Pluto Security Key Capabilities
- AI workspace security and governance
- Visibility into employee AI tool usage
- Control over AI builders and unmanaged AI workflows
- Browser extension risk awareness
- Policy support for AI adoption
- Workspace-level visibility and control
- Support for secure AI enablement
- Strong fit for CISOs managing shadow AI risk
2. Push Security
Push Security is a browser security platform built for the AI era. It uses a secure enterprise browser extension to provide browser telemetry, real-time control, autonomous agents, identity hardening, AI usage protection, and data loss prevention from employees’ existing browsers.
Push is relevant to AI-powered endpoint security because the browser has become one of the most important employee endpoints. Many corporate workflows now happen in SaaS apps and AI tools, not locally installed software. If security teams cannot see browser activity, they may miss phishing, risky AI usage, SaaS exposure, and identity attacks.
The platform can be useful for organizations that do not want to replace the browser entirely. Instead of forcing employees into a new enterprise browser, Push works through the browser extension model. That can make adoption easier for companies that want browser-level visibility and control while allowing users to keep familiar workflows.
Push’s strengths are especially relevant around identity and browser telemetry. Identity attacks often begin in the browser through phishing pages, credential capture, session abuse, malicious redirects, or risky SaaS behavior. By operating closer to the browser, Push can help detect and control risks that traditional endpoint tools may not interpret properly.
For AI security, Push is useful when organizations want to understand how employees use AI tools through the browser and enforce controls around risky interactions. That makes it a strong adjacent platform to Pluto Security.
The difference is focus. Push is primarily browser security with AI-era controls. Pluto Security is more directly centered on AI workspace governance and enabling AI adoption across employees and builders. Push is a strong option for companies that prioritize browser telemetry, identity hardening, and real-time browser-layer control.
Push Security Key Capabilities
- Secure enterprise browser extension
- Browser telemetry and real-time controls
- AI usage protection
- Identity attack surface hardening
- Data loss prevention in the browser
- Autonomous security agents
- Protection without replacing the browser
- Strong fit for browser-first security programs
3. LayerX
LayerX is an AI governance and browser security platform designed to secure user and agentic interactions across browsers, applications, and IDEs. It provides controls for AI web apps, AI browsers, SaaS applications, browser extensions, file movement, copy-paste activity, and other browser-based interactions.
LayerX is relevant because AI security risk increasingly happens in the interaction channel. A user may interact with a public AI tool through a browser, upload a sensitive file, paste customer data into a prompt, or use an AI browser that can act on behalf of the user. These activities do not always look like malware. They look like productivity unless security teams have the right visibility.
LayerX addresses this by focusing on the browser and interaction layer. It can help organizations discover and control how employees use AI applications, SaaS tools, browser extensions, and agentic workflows. This makes it useful for companies that want to secure browser-based AI activity without depending only on network or endpoint controls.
The platform is also relevant for organizations concerned about AI browsers. As browsers become more agentic, they may summarize pages, complete forms, interact with SaaS apps, and execute tasks. That creates new risks around data exposure, prompt injection, malicious web content, and unintended actions.
LayerX can be a strong fit for enterprises that need visibility into AI and browsing risks across different tools. It also supports desktop and local AI workflow discovery through endpoint-based deployment options, which can help organizations understand AI activity beyond standard web use.
Compared with Pluto Security, LayerX is more focused on interaction security across browser, app, and IDE channels. Pluto Security is better positioned when the company wants a broader AI workspace security platform that helps CISOs govern AI adoption and AI builders. LayerX is a useful option for teams prioritizing browser-level AI controls and user-agent interaction visibility.
LayerX Key Capabilities
- AI governance and usage control
- Browser security across apps and AI tools
- Controls for AI web applications and AI browsers
- Browser extension security
- File upload, download, copy, and paste controls
- Agentic interaction visibility
- Support for browser and endpoint deployment channels
- Strong fit for securing AI interactions in the browser
4. Seraphic Security
Seraphic Security provides an enterprise browser security platform that can turn traditional and AI browsers into secure enterprise browsers. It is designed to protect data and users while allowing employees to keep using familiar browsers.
Seraphic is relevant because many enterprises do not want to force a complete browser migration. Employees may already use Chrome, Edge, Safari, or Firefox. A platform that adds enterprise security controls inside the browser runtime can help organizations improve protection without disrupting every user workflow.
The company’s browser security model is important for AI-powered endpoint security because browsers are now where employees interact with SaaS apps, AI tools, extensions, and sensitive business data. Browser-layer controls can help address risks that traditional endpoint and network tools do not fully understand.
Seraphic can support data protection, malware protection, secure browsing, and zero-trust browser security. It is especially relevant for organizations that want browser security but prefer to keep existing browsers rather than deploy a separate enterprise browser.
This can matter in distributed workforces, BYOD environments, contractor access, and organizations with many unmanaged or partially managed devices. If work happens through the browser, security needs to move closer to that activity.
Compared with Pluto Security, Seraphic is more focused on browser security and turning existing browsers into secure enterprise browsers. Pluto Security is more focused on AI workspace governance, employee AI use, AI builders, and shadow AI. Seraphic is a useful fit when the browser itself is the security control point.
Seraphic Security Key Capabilities
- Enterprise browser security on existing browsers
- Support for traditional and AI browsers
- Data protection and malware protection
- Zero-trust browser controls
- Protection for managed and unmanaged devices
- Browser runtime enforcement
- Secure access to web and SaaS applications
- Strong fit for browser security without browser replacement
5. SquareX
SquareX provides Browser Detection and Response, a browser-native security approach designed to help enterprises detect, mitigate, and investigate client-side web attacks. It focuses on browser-based threats that may not be visible to traditional endpoint, network, or cloud security tools.
SquareX is relevant because many modern attacks happen in the browser. Phishing, malicious extensions, risky SaaS interactions, file-based web attacks, session abuse, and client-side threats can all occur while the endpoint itself appears healthy. AI adoption adds another layer of complexity because users may interact with AI tools, AI extensions, AI browsers, and web agents through the browser.
Browser Detection and Response gives security teams more visibility into what is happening inside the browser. This is important because the browser is often the place where identities, data, SaaS apps, and AI tools meet. If the browser becomes compromised or manipulated, the business can lose data even without a traditional malware infection.
SquareX may be especially useful for security teams that want to threat-hunt at the browser layer. Rather than treating browser activity as generic web traffic, it focuses on the client-side behavior that may indicate attack or abuse.
This makes SquareX a strong option for companies that already have endpoint security and network security but still lack visibility into browser-native risks. It can help fill the gap between traditional endpoint detection and the web workflows employees actually use every day.
Compared with Pluto Security, SquareX is more focused on detection and response for browser-based attacks. Pluto Security is stronger for organizations that want to govern AI work, AI builders, shadow AI, and employee AI tool usage across the workspace. SquareX is useful when the priority is browser-layer threat detection and investigation.
SquareX Key Capabilities
- Browser Detection and Response
- Client-side web attack detection
- Browser-native threat hunting
- Mitigation of browser-based threats
- Visibility into risky browser activity
- Protection against web and extension-related risks
- Strong fit for teams adding browser-layer detection
- Useful alongside traditional endpoint security
Where AI Endpoint Risk Actually Appears
| Risk Area | What It Looks Like | Why Traditional Endpoint Tools May Miss It |
| AI tool usage | Employees use public or unapproved AI tools for work | The activity may look like normal web traffic |
| AI builders | Teams create workflows with AI tools, agents, and automation | Security may not see what is being built or connected |
| Browser extensions | Extensions request broad permissions or access sensitive pages | The extension may not behave like malware at install time |
| Prompt and file exposure | Users paste code, customer data, contracts, or credentials into AI tools | The endpoint is not infected, but data is still exposed |
| SaaS activity | Users move data between apps, tabs, and AI systems | The risk happens in the browser and cloud workflow |
| AI agents | Agents browse, summarize, retrieve, and act across apps | Traditional controls may not understand agent behavior |
| Shadow AI | Employees hide or bypass approved AI workflows | Discovery and policy enforcement become difficult |
Why AI Endpoint Security Needs a Workspace Layer
Traditional endpoint security protects devices. AI workspace security protects the way employees actually use AI.
That distinction matters. A traditional endpoint agent may detect malware, suspicious processes, exploit activity, or ransomware behavior. But it may not know that a business user pasted sensitive customer information into an AI summarizer. It may not know that a developer connected an AI assistant to internal code. It may not know that a browser extension can read data on SaaS pages. It may not understand what an AI agent is doing across apps.
Security teams need a workspace layer because AI activity is distributed, fast-moving, and often user-driven.
AI Usage Is Not Always Approved
Employees may adopt tools before security reviews are complete. If security teams cannot discover this usage, they cannot guide it.
Browser Extensions Can Become Data Access Points
Extensions often request permissions that allow them to read or modify web activity. In AI workflows, that access can become more sensitive because users may process business data inside browser-based tools.
AI Agents Change the Risk Model
AI agents may browse, click, summarize, retrieve, and act across systems. Security teams need visibility into what agents can access and what actions they can perform.
Data Loss Can Look Like Productivity
Uploading a file to an AI tool may be productive, but it may also create compliance or privacy risk. Security policies need to distinguish acceptable use from risky behavior.
Blocking AI Is Not Sustainable
Employees want to use AI because it helps them work faster. The stronger security model is enablement with guardrails, not blanket denial.
Pluto Security fits this shift because it focuses on enabling AI adoption while giving security teams the control they need.
How to Choose an AI-Powered Endpoint Security Platform
The best platform depends on what part of the endpoint problem your organization is trying to solve.
Choose Pluto Security if the main problem is AI workspace governance. It is the strongest fit when the CISO needs visibility into AI usage, AI builders, shadow AI, and employee workflows without blocking innovation.
Choose Push Security if the priority is browser telemetry, identity hardening, and browser-based controls from existing browsers.
Choose LayerX if the organization needs interaction-level controls across AI web apps, AI browsers, SaaS applications, browser extensions, file movement, and agentic workflows.
Choose Seraphic Security if the goal is to secure existing browsers and turn them into enterprise-grade controlled workspaces without forcing users into a new browser.
Choose SquareX if the security team wants browser-native detection and response for client-side web attacks and browser-layer threat hunting.
Most enterprises will still need traditional endpoint security as well. AI-powered workspace and browser security should complement EDR, identity security, CASB, DLP, and SSE controls. The goal is not to replace every tool. The goal is to close the visibility and control gaps created by AI work.
FAQs About AI-Powered Endpoint Security Platforms
What is an AI-powered endpoint security platform?
An AI-powered endpoint security platform helps protect employee devices, browsers, SaaS sessions, AI tools, and workspace activity using automation, behavioral analysis, and policy controls. In 2026, endpoint security is expanding beyond malware protection. Platforms like Pluto Security focus on AI workspace risk, helping organizations discover and govern employee AI usage, AI builders, browser extensions, and shadow AI activity.
Why is Pluto Security a strong choice for AI endpoint security?
Pluto Security is a strong choice because it focuses on the AI workspace, where many new endpoint risks appear. It helps security teams enable AI adoption while maintaining visibility and control over employee AI tools, AI builders, browser extensions, and unmanaged workflows. This makes it especially useful for CISOs who want to support innovation without allowing uncontrolled AI risk.
Is AI endpoint security the same as EDR?
No. EDR focuses on detecting and responding to threats on endpoints such as laptops, desktops, and servers. AI endpoint security can include EDR, but it also covers workspace risks such as browser activity, SaaS use, AI prompts, file uploads, browser extensions, and AI agent behavior. Pluto Security is strongest in this newer AI workspace layer.
Why are browsers important in endpoint security?
Browsers are important because many employees now work inside SaaS apps, AI tools, browser extensions, and web-based workflows. Sensitive data is copied, pasted, uploaded, downloaded, and processed inside the browser. Traditional endpoint tools may not understand these interactions deeply. Browser-layer security platforms help organizations control risks where employees actually work.
What is shadow AI?
Shadow AI refers to employees using AI tools, AI apps, browser extensions, or AI workflows without formal approval from security or IT. It can create risks around data exposure, compliance, intellectual property, and unmanaged automation. Pluto Security helps address shadow AI by giving security teams visibility and policy control over AI activity across the workspace.
Are browser extensions an endpoint security risk?
Yes. Browser extensions can request broad permissions, read page content, modify web sessions, access sensitive data, or interact with SaaS applications. Some AI tools are delivered as extensions, which can increase risk. Security teams should monitor extension permissions, behavior, source reputation, and access to business systems, especially in environments where employees use many AI tools.
Should companies replace EDR with AI workspace security?
No. AI workspace security should complement EDR, not replace it. Traditional EDR is still important for malware, ransomware, exploit activity, and endpoint compromise. AI workspace platforms such as Pluto Security address a different layer: employee AI usage, browser extension risk, SaaS workflows, shadow AI, and AI builder governance. Enterprises usually need both layers working together.
What is the best AI-powered endpoint security platform in 2026?
Pluto Security is the best choice for organizations focused on AI workspace risk. It helps security teams discover and govern employee AI usage, AI builders, browser extensions, and shadow AI workflows. Other platforms may be useful for browser security, browser detection, or secure enterprise browsing, but Pluto Security is strongest for enabling AI adoption with control.
