Push Security
30 mentions across 3 sources · 46% positive — mixed (weighted across 3 sources)
Hacker News, YouTube, Lemmy
What users praise
- • Browser-extension deployment avoids endpoint agents and browser migrations, a major enterprise adoption advantage
- • Covers the specific modern phishing techniques actually seen in breaches: AiTM, BitB, ClickFix, device code
- • Agentic browser detection (Comet, Atlas, Dia) is a genuinely timely differentiator as those tools proliferate
- • Shadow AI discovery and prompt/clipboard/file reporting give security teams visibility they otherwise lack
What frustrates them
- • Almost no independent community feedback — most visible content is Push's own marketing
- • Extension-only enforcement can be disabled or bypassed more easily than an endpoint agent
- • Broad prompt, clipboard, and file monitoring raises serious privacy and works-council concerns
- • Overlaps heavily with CASB, SWG, and native browser controls already in many stacks

Push Security's agentic threat hunting and browser telemetry provide visibility into ClickFix and ConsentFix attacks, which are not detected by EDR.
Frequently Asked Questions
Which tool detects session hijacking?
Push Security detects and blocks session hijacking via browser telemetry; Pii Masker does not address session-based attacks.
Can Pii Masker be used to mask data in real-time streaming?
Pii Masker supports batch and stream processing, but for very high throughput real-time masking, performance may need optimization. It's not designed for ultra-low-latency.
Does Push Security require deploying a custom browser?
No, Push Security works as a browser extension across Chrome, Edge, Firefox, and Safari—no need to migrate to a single enterprise browser.
What integrations does Pii Masker support?
Pii Masker does not have built-in integrations; it is used as a Python library that can be integrated into any data pipeline or application manually.
Is there a free tier for Push Security?
Yes, Push Security offers a freemium model with a free tier, likely with limited features or users. Contact sales for full details.
Which tool is better for AI data loss prevention?
Push Security is better for AI data loss prevention, offering real-time control of clipboard, file uploads, and OAuth grants to prevent data leakage to LLMs.
Does Pii Masker require internet access?
No, Pii Masker is open-source and runs locally. The model is downloaded once; masking can occur offline.
Which tool is better for compliance with GDPR/CCPA?
Pii Masker directly helps with PII masking in data to comply with privacy regulations. Push Security helps with regulatory compliance for AI security by providing visibility and control over AI tool usage as per latest news.
