Know the moment your email address surfaces in a breach. Not weeks later.

Breachtide correlates four independent breach intelligence feeds for every email address you verify, hashes the result, and delivers a graded alert only when the picture genuinely changes. No noise. No duplicate notifications. No surveillance of addresses you do not own.

Coverage

Four independent feeds. One coherent intelligence stream.

Most monitoring tools surface a single public index. Breachtide cross-references four independent feeds, deduplicates the overlap, and ranks the result by what actually matters to a defender: whether a usable credential is now in circulation.

Archive

Historical breach archives

Decades of compiled breach corpora indexed by exact email address. The first place to confirm whether a credential set has ever been exposed.

Combolists

Live credential combolists

Active stuffing combolists harvested from forums and chat dumps. The earliest reliable signal that a working password is in circulation.

Public index

Public breach index

A continuously refreshed index of disclosed breaches. Names the source database and the earliest known appearance of the address.

Enriched

Field-level breach detail

On a confirmed hit, the enriched lookup returns the exact values that leaked: passwords, hashes, government ID, address, phone. Encrypted at rest for 90 days, visible on every paid plan. The Free tier sees the field categories without the values themselves.

Signal, not noise

The same breach across three feeds becomes one alert.

Each sweep produces a sorted, hashed result. If the hash matches the previous sweep, nothing happens. If it changes, the delta is classified by severity and sent once, with the exact fields that newly appeared and a dashboard link to inspect the rest.

< 5 min from sweep to alert 30-day alert history
  • Critical
    A working password is now in circulation. Rotate immediately. This is the alert that matters most.
  • Warning
    A new sensitive field appeared. Date of birth, physical address, phone, or government ID tied to the monitored address.
  • Info
    A new source database appeared, but no sensitive values were exposed. Useful context, no action required.
Intelligence pipeline

From sign-up to first alert in under five minutes.

Every step is recorded, signed, and replay-safe. The same sequence runs whether the cadence is weekly, daily, or twice-weekly priority.

01

Verify ownership

A one-time confirmation link goes to the inbox. Without that click, no sweep ever runs.

02

Sweep all sources

Each verified address is queried across four independent feeds on a per-plan cadence.

03

Hash and compare

The sorted result is hashed against the previous sweep. Identical hash, no alert.

04

Classify and deliver

A change is graded by severity and sent once, with the exact fields that newly appeared.

Alert payload

Structured, signed, and ready for downstream automation.

Webhook deliveries are signed with HMAC-SHA256 against a per-account secret you rotate at any time. Email deliveries land in plain prose with the same field-level detail. Either format names the source, the delta, and the fields that newly appeared.

  • JSON body with stable schema and versioned event names
  • X-Breachtide-Signature header for every webhook
  • Idempotent retry on receiver failure with exponential backoff
  • 30-day audit log of every delivery attempt

The only personal data Breachtide stores is the verified email address you ask it to monitor. Crypto checkout means even the billing identity stays off the books.
