Comet
AI-native Chromium browser that turns the agent into a first-class actor for browsing and workflow automation, though its enterprise posture depends heavily on compensating controls around prompt injection, data exposure, and limited native management tooling.
Profile Overview
Comet is an AI-native browser developed by Perplexity AI and officially announced in July 2025 as the company's first browser product. Built on Chromium, Comet aims to turn the browser from a passive rendering surface into an active assistant that can understand pages, execute tasks, and automate workflows. Initial releases targeted Windows and macOS, with Android following, and early access distribution focused on a limited user base before broader rollout.
Market Position
Comet positions itself as a personal AI assistant in browser form, targeting power users, knowledge workers, and early-adopter enterprises who want AI tightly integrated into daily browsing. It enters a market dominated by mainstream Chromium-based browsers (Chrome, Edge, Brave) and emerging AI browsers, differentiating on the depth of agentic automation and Perplexity's search-centric capabilities. As of late 2025, Comet remains a newcomer with a comparatively small user base, and enterprise adoption is largely in exploratory or pilot stages.
Technical Foundation
Comet is based on Chromium and uses the Blink engine, maintaining compatibility with Chrome extensions and modern web standards while adding an AI orchestration layer. Its architecture integrates conversational AI directly into the browser, enabling the agent to read and summarize current pages, maintain context across tabs, and perform multi-step actions such as filling forms, organizing tabs, and interacting with email and calendar services.
Enterprise Adoption
Perplexity markets Comet to enterprises as part of Perplexity Enterprise, highlighting speed, data-tight configurations, and AI-enabled workflows integrated with corporate sources. Public enterprise-oriented materials focus on agentic productivity and integration with email, calendars, and knowledge systems rather than on a detailed browser policy catalog or admin console. Comet's suitability for broad enterprise deployment depends heavily on the organization's ability to manage AI-related risks: prompt injection, agent hijacking, and data governance, using external controls and Perplexity's enterprise configurations.
Deployment Posture
Comet exposes an AI-first browsing model with enterprise-focused messaging via Perplexity Enterprise, but current large-scale deployments require strong surrounding identity, DLP, and security controls rather than relying on a mature browser-native management stack.
Deployment Guidance
Comet is distributed as a Chromium-based browser with integrated AI and is tied to Perplexity's broader platform and enterprise offerings. Public documentation focuses on user-facing features and enterprise value propositions rather than detailed, browser-specific deployment guides or policy catalogs. Organizations deploying Comet at scale should combine Perplexity's enterprise configuration options with existing device and identity management tools.
Deployment Options
| Method | Best For | Key Features |
|---|---|---|
| Direct installer via Perplexity | Small pilots and early adopters | Download Comet for Windows or macOS; suitable for initial evaluations |
| Software distribution & MDM | Organizations with existing device management | Package installers into MDM tools to push to selected users |
| Perplexity Enterprise configuration | Enterprises trialing Comet | Bind Comet access to corporate identities with server-side configurations |
Update Channels
- Ongoing stable/beta updates: Comet is iterated frequently to refine AI behavior and browser capabilities
- No public ESR-style track: Enterprises must accommodate regular updates and validate changes in test cohorts
Extension Management
Comet uses Chromium and can support Chrome-compatible extensions, but there is limited public information on Comet-specific extension governance. Organizations should apply extension policies via existing Chromium configurations or restrict extension installation in sensitive contexts, and focus on governing Comet's AI agent permissions rather than extensions alone.
Best Fit Scenarios
- Innovation and security labs evaluating agentic browsers, where Comet's AI automation is tested on synthetic or low-sensitivity data with close monitoring from security teams.
- Knowledge-worker pilot groups in organizations already trialing Perplexity Enterprise, looking to explore AI-driven summarization, research, and task automation within a controlled cohort.
- Teams with strong browser and SaaS security posture (identity-aware proxies, CASB, and DLP) that can bound Comet's access to critical systems while assessing productivity gains.
Caution Scenarios
- Enterprises with strict SSO-boundary and session-confidentiality requirements, where an agent that can read and act across authenticated tabs creates unacceptable lateral-movement and data-exfiltration risk.
- Regulated industries that need detailed, auditable controls over AI data flows, model behavior, and retention, beyond what is currently documented for Comet's browser-native configuration.
- Organizations expecting a conventional enterprise browser with mature ADMX/MDM policy catalogs, well-established admin consoles, and large-scale reference deployments.
Secure Comet in Your Enterprise
Keep Aware's lightweight browser extension provides real-time threat detection, data leakage prevention, and protection against evolving attacks that exploit human error.
Key Risks & Considerations
Comet represents an agentic browser where the primary differentiator is an integrated AI capable of reading, remembering, and acting on user content across sessions. This changes traditional browser risk assumptions: security teams must consider the browser as an autonomous actor that can perform actions based on instructions from untrusted content.
Security Architecture
Comet retains Chromium's security model. The differentiated risks stem from the AI layer:
- Agentic capabilities: Comet's AI can click buttons, fill forms, navigate across tabs, and interact with APIs
- Cross-session memory: The AI retains knowledge of prior pages, forms, and connected accounts across tabs and time
- Deep integrations: Comet can read and act on Gmail, calendars, and Notion content
Agent Hijacking & Prompt Injection
Security research describes concrete attack scenarios against Comet's AI:
- Indirect prompt injection: Attackers can embed instructions in page content that override user prompts
- Agent hijacking: A malicious link can direct the AI to access emails, credentials, and connected apps
- Persistent influence: The AI's memory can be abused to continue harmful behavior across other sites
Privacy & Telemetry Considerations
| Feature | Data Sent | Can Disable? |
|---|---|---|
| AI interactions | Queries and page content sent to Perplexity backends | Users control when to invoke AI; enterprise deployments can restrict usage patterns |
| Tracking & personalization | Data used to personalize suggestions | Privacy settings can limit some tracking |
| Local vs cloud storage | Some content stored locally; shared when needed for AI tasks | Users can use stricter modes or incognito |
Vendor Dependency
Adopting Comet introduces dependency on Perplexity AI as both browser provider and AI platform. Security architects should evaluate Comet within the context of their broader Perplexity relationship, including contractual commitments and data-handling terms.
