Partly fits

Sublime Platformpartial · 65

Its core purpose is email-attack detection and prevention, but it is targeted at security/detection engineers and teams rather than non-expert individual users.

Won’t cover: Built as an email detection platform for defenders and engineers, so it is not packaged as a consumer-ready, turn-key anti-phishing product for an individual.

HomePhishpartial · 58

Provides realistic phishing simulations and family-focused training, which helps reduce human risk but is primarily a training tool rather than an automatic link blocker.

Won’t cover: Focuses on simulated phishing exercises and awareness for families rather than automatic, real-time blocking of malicious links in your browser or inbox.

ScamDrillpartial · 55

Delivers simulated scam exercises for businesses and families to build recognition skills, offering awareness but not direct link-blocking or inbox integration for individuals.

Won’t cover: Designed to create safe simulated scams and training rather than acting as an in‑browser or in‑inbox blocker for live phishing links.
