Comet - Own the Browser - Is Comet safe?

Profile Overview

Archetype: AI-native agentic browser prioritizing consumer convenience over enterprise governance

Primary Differentiator: Deep Perplexity AI integration with agentic capabilities that can interact with tabs, forms, email, and calendar autonomously

Deployment Posture:

Consumer-First

Summary Judgment

Comet represents the bleeding edge of AI-browser integration, offering genuinely useful agentic capabilities for research and automation. However, its architectural requirement for deep data access, documented security vulnerabilities (CometJacking, prompt injection), and hidden system-level extensions make it unsuitable for enterprise deployment. Best suited for individual power users in non-sensitive contexts who accept the privacy tradeoffs.

Deployment Posture

Specialized

Consumer-First

Enterprise-Tolerable

Enterprise-Native

Comet is primarily designed for individual users. While enterprise deployment is possible, it is not a vendor priority and may require additional configuration or compensating controls.

Deployment Guidance

Best Fit Scenarios

Individual knowledge workers conducting open-source research without confidential data
Power users seeking AI-assisted browsing for personal productivity
Early adopters willing to trade privacy for cutting-edge agentic features

Caution Scenarios

Any environment handling confidential, proprietary, or regulated data
Enterprise deployments requiring security governance and auditability
Organizations unable to accept data processing through third-party AI cloud services

Dimension Ratings

Each dimension is rated on a 5-point scale from Absent (1) to Hardened (5).

Security

1 —

Critical vulnerabilities documented (CometJacking, prompt injection, MCP API exploits); hidden extensions with system-level access; requires granting AI access to all browsing data.

Reliability

3 —

Chromium foundation provides baseline stability; memory recall features inconsistent; rapid iteration may introduce regressions.

Performance Efficiency

3 —

Standard Chromium performance; AI processing adds latency and cloud dependency for core features.

Usability

4 —

Intuitive AI sidebar and multi-tab intelligence genuinely useful; Spaces feature aids organization; familiar Chromium interface.

Compatibility

4 —

Chromium-based with broad web compatibility; supports most Chrome extensions except new-tab-modifying ones.

Maintainability

1 —

No enterprise management tooling; hidden extensions cannot be disabled; no GPO/MDM policy support documented.

Portability

2 —

Available on Windows, macOS, Android; iOS in development; no Linux support; requires Perplexity account.

Functional Suitability

3 —

Excellent for AI-assisted research and automation; core browsing adequate; agentic features compelling but narrow use case.

Enterprise Readiness

1 —

Not enterprise-ready; no management controls, documented security issues, mandatory cloud data processing, and vendor dismissed vulnerability reports.
