Push Security
30 mentions across 3 sources · 34% positive — critical (weighted across 3 sources)
Hacker News, YouTube, Lemmy
What users praise
- • Interaction-level detection catches ClickFix, OAuth consent phishing and pastes that URL-reputation tools miss
- • Explicit AiTM, BitB and BitM reverse-proxy coverage addresses the phishing class that beats MFA
- • Shadow-AI discovery and policy enforcement is a genuinely differentiated control for 2025-era risk
- • No endpoint agent, no network appliance — deployment is extension-based and fast
What frustrates them
- • Nearly no independent community reviews — Reddit, Product Hunt and GitHub data is essentially absent
- • Browser-extension-only coverage leaves non-browser auth paths and mobile-first flows unmonitored
- • Blocking at the paste/upload/consent level risks interrupting legitimate workflows and generating tickets
- • Autonomous threat-hunting agents risk adding noise to already-overloaded SOC alert queues

Proton Mail vs Push Security: which should you choose?
Push Security and Proton Mail serve entirely different needs — browser threat defense vs. private email.

Choose Proton Mail for end-to-end encrypted email and a privacy suite. They are complementary, not competitive.
Can Push Security replace Proton Mail for email security?
No. Push is a browser security platform that does not provide email service; it protects against attacks that happen within browsers, including malicious OAuth and session hijacking. Proton Mail is an email provider with encryption.
Does Proton Mail protect against AiTM phishing attacks?
