Choose AgentSeal if you're a developer or security engineer needing open-source, code-level scanning for AI agent configurations, MCP servers, and prompt injection. Choose Push Security if you're an enterprise security team needing browser-based detection and control over phishing, AI tool usage, and identity attacks — it's cloud-based and covers a broader threat landscape. Both are free to start but serve very different attack surfaces.

What real users say: Agentseal vs Push Security

Not marketing copy and not our opinion — a structured sweep of public discussion (reviews, forums, communities and video comments), showing what people praise and what they complain about for each tool.

Agentseal

20 mentions across 2 sources · 65% positive

Hacker News, Product Hunt

What users praise

  • • Fully open-source and free with no enterprise contracts required.
  • • Covers multiple attack surfaces: prompts, MCP servers, skill files.
  • • 380+ attack probes for comprehensive vulnerability detection.
  • • Deterministic probes with unique canaries for reproducible CI results.

What frustrates them

  • • Very limited community adoption—hard to gauge real-world effectiveness.
  • • Prompt scanning requires paid API access to an LLM provider.
  • • No plug-and-play cloud version—must run CLI or integrate yourself.
  • • Dashboard is basic and lacks advanced reporting features.

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.

Frequently Asked Questions

Agentseal vs Push Security: which should you choose?

Choose AgentSeal if you're a developer or security engineer needing open-source, code-level scanning for AI agent configurations, MCP servers, and prompt injection. Choose Push Security if you're an enterprise security team needing browser-based detection and control over phishing, AI tool usage, and identity attacks — it's cloud-based and covers a broader threat landscape. Both are free to start but serve very different attack surfaces.

Which tool is better for detecting prompt injection?

AgentSeal is purpose-built for prompt injection detection with 380+ adversarial probes and deterministic canaries. Push Security does not target prompt injection; it focuses on browser-level threats.

Can I use AgentSeal without LLM API keys?

Yes, for machine-level scans (Guard, Shield, Scan-MCP) no API keys are needed. Only prompt scanning requires access to an LLM of your choice.

Does Push Security replace an endpoint DLP?

No, Push Security is a browser-based DLP, not a full endpoint DLP. It covers clipboard, file uploads, and AI tool interactions in-browser, but not file system or network-level DLP.

Is AgentSeal suitable for non-developers?

AgentSeal is CLI-based and requires technical knowledge to set up and interpret results. Non-technical users may find Push Security's browser extension approach more accessible.

Which tool has better integration with identity providers?

Push Security integrates with Okta, Azure AD, Google Workspace, Slack, and more. AgentSeal does not integrate with identity providers; it focuses on LLM providers and CI/CD.

Can I self-host Push Security?

No, Push Security is cloud-based only. AgentSeal is fully self-hosted and open-source.

What is the latest major finding from AgentSeal?

In March 2026, AgentSeal reported that 66% of 1,808 MCP servers had security findings, and validated exploits for 6 high-profile MCP servers, demonstrating real-world impact.

What is the latest news from Push Security?

In June 2026, Push Security experienced a poisoned tenant attack via a fake OpenAI org invitation, highlighting risks of OAuth-based identity attacks, and published a SANS AI security maturity model.
