Agentsh vs Push Security
Side-by-side comparison of features, pricing, and ratings
At a glance
| Dimension | Agentsh | Push Security |
|---|---|---|
| Pricing | Free (open-source) | Freemium |
| Primary Focus | Execution-layer security: syscall-level policy for AI agents | Browser security: AiTM phishing, session hijacking, AI tool usage control |
| Deployment | CLI shim between agent harness and OS | Browser extension + cloud platform |
| Key Differentiator | Prompt-proof syscall enforcement (bypasses jailbreaks) | Browser telemetry + autonomous threat hunting agents |
| Best For | Developers deploying autonomous AI agents in production | Security teams securing browser-based attacks and AI tool use |
| Integrations | E2B, Sprites, Daytona, Blaxel, Vercel, Modal, Cloudflare, Deno, exe.dev, Runloop, Freestyle, Tensorlake | Okta, Azure AD, Google Workspace, Slack, Splunk, Snowflake |
Choose Push Security if your priority is stopping browser-based attacks (AiTM phishing, session hijacking) and controlling employee AI tool usage across Chrome, Firefox, etc. Choose Agentsh if you're building autonomous AI agents and need runtime syscall-level policy enforcement that even prompt injections can't bypass. They solve different problems: browser vs. execution layer.
Syscall-level security enforcement for AI agents, prompt-proof and deterministic.

Agentsh
15 mentions across 4 sources · 64% positive — mixed
Hacker News, Bluesky, GitHub, Lemmy
What users praise
- • Prompt-proof enforcement at the syscall level, resilient to jailbreaks.
- • Captures subprocess trees including pip installs and npm scripts.
- • Full audit log with approval gates for risky operations.
- • Drop-in deploy: no code changes, works with any agent harness.
What frustrates them
- • Regression bugs in recent releases break specific environments.
- • Network domain denies bypassed by subprocesses without proxy env.
- • Cannot enforce database query restrictions at execution layer.
- • JSON output mode leaks non-JSON warnings in v0.19.1.

Push Security
30 mentions across 3 sources · 43% positive — mixed
Hacker News, YouTube, Lemmy
What users praise
- • Works as a lightweight extension across all major browsers without forcing a single proprietary browser.
- • Detects advanced threats like AiTM phishing, ClickFix, session hijacking, and malicious OAuth flows.
- • Autonomous hunting agents analyze browser telemetry to write and deploy detection rules at machine speed.
- • Provides comprehensive AI usage governance: inventory, prompt monitoring, file upload blocking, and unsanctioned app control.
What frustrates them
- • No independent community feedback or real-user reviews available to verify claims.
- • Requires advanced security expertise to configure and interpret telemetry effectively.
- • High-fidelity telemetry collection may trigger privacy and compliance red flags.
- • Potential for false positives in blocking legitimate OAuth and extension actions.

- Security team facing AiTM phishing attacksPick: Push Security
Push Security specializes in detecting and blocking adversary-in-the-middle (AiTM) phishing, session hijacking, and malicious OAuth integrations using browser telemetry.
- Developer deploying autonomous AI agents in productionPick: Agentsh
Agentsh provides execution-layer syscall policy enforcement that stays effective even when agents are jailbroken, and integrates with sandbox platforms like E2B and Vercel.
- IT admin wanting to control employee AI tool usagePick: Push Security
Push Security offers real-time AI tool visibility, usage control, and in-browser DLP to prevent data leakage to LLMs without requiring an enterprise browser.
- Compliance officer needing audit logs for agent operationsPick: Agentsh
Agentsh provides full audit logs with subprocess tree visibility, capturing every syscall for compliance and forensic analysis.
- Solo founder with limited budgetPick: Agentsh
Agentsh is free and open-source, requiring no financial commitment, while offering robust security for AI agents. Push Security's freemium may also suffice for basic needs.
Frequently Asked Questions
Agentsh vs Push Security: which should you choose?
Choose Push Security if your priority is stopping browser-based attacks (AiTM phishing, session hijacking) and controlling employee AI tool usage across Chrome, Firefox, etc. Choose Agentsh if you're building autonomous AI agents and need runtime syscall-level policy enforcement that even prompt injections can't bypass. They solve different problems: browser vs. execution layer.
Which tool is better for preventing data loss from AI tools?
Push Security offers in-browser DLP for AI tools (clipboard, file uploads) and real-time AI usage control, making it ideal for preventing data leakage to LLMs. Agentsh does not focus on browser-based data loss but prevents secrets exposure from agent executions at the syscall level.
Can Agentsh be used without a cloud console?
Yes, Agentsh is a CLI-based tool with no centralized SaaS dashboard yet. It's designed for developers comfortable with terminal-based deployment.
Does Push Security work on mobile browsers?
Yes, Push Security detects mobile phishing via SMS/QR codes, but its core browser extension works on desktop browsers (Chrome, Edge, Firefox, Brave).
Which tool integrates with identity providers?
Push Security integrates with Okta, Azure AD, and Google Workspace. Agentsh does not integrate with identity providers, focusing instead on sandbox platforms like E2B, Vercel, and Modal.
Are both tools free?
Push Security offers a freemium model (basic features free, advanced likely paid). Agentsh is entirely free and open-source.
Which tool protects against prompt injection?
Agentsh's execution-layer enforcement is prompt-proof—it overrides any agent prompt or tool output, making it effective against prompt injection and jailbreaks. Push Security focuses on browser-based attacks, not agent prompts.
Can I use both tools together?
Yes, they address different layers: Push Security for browser security and AI tool usage, Agentsh for AI agent runtime security. They can complement each other in an organization's security stack.
Does Push Security require an enterprise browser?
No, Push Security works as a browser extension on standard browsers (Chrome, Edge, Firefox, Brave) without forcing a browser migration.
