NeoShield Exposure Check vs Have I Been Pwned
You want to know whether an email or domain is exposed in known breaches — and what to do about it.
Have I Been Pwned (HIBP) is the reference dataset for breach lookups and does that one job superbly. NeoShield's Exposure Check uses the same privacy-preserving k-anonymity approach for breach lookups, then adds domain spoofability (SPF/DKIM/DMARC) analysis and plain-English remediation — so an email or domain check and its fix live in one screen.

| Password exposure check | Via linked tools | ✓ Yes |
| Domain spoofability: SPF / DKIM / DMARC | ✓ Yes | — No |
| Plain-English remediation guidance | ✓ Yes | Limited |
| Part of a wider defensive toolkit | ✓ Yes | — No |

When NeoShield is the better fit
- You want a breach check AND a domain spoofability check together.
- You want next-step guidance, not just a yes/no.
- You'll use other defensive tools (headers, JWT, phishing) in the same place.
The verdict
If you just need the canonical breach dataset, HIBP is excellent. If you want a breach check plus domain spoofability and fix guidance in one free screen, use NeoShield's Exposure Check.
