Ask HN: We built an phishing site discovery tool – worth turning into a product?

We built a tool that detects and monitors phishing sites impersonating a specific brand (our client), and automates the takedown process. It pulls data from various sources multiple times a day, filters millions of domains daily using domain similarity and logo detection, and automates reporting to blocklists, registrars, and hosting providers. We're considering turning this into a standalone SaaS product — self-serve, subscription-based, likely priced at $400–600/month.

A few questions:

Do you think there's space in the market for a focused tool like this, given that large vendors bundle similar functionality into broader suites?

In your experience, who typically makes the buying decision for tools like this (and in this price point) — security teams, legal, compliance, or C-level?

Does the price point sound reasonable?

Anything you'd expect from a tool like this that we might be missing?

Would love any feedback or suggestions.

Thanks HN! —J
