Continuous Security

Breach & Credential Monitoring

Twice-daily monitoring of breach dumps, infostealer logs and dark-web sources for credentials tied to your domains — so you can reset passwords before they are used against you.

Stolen credentials are one of the most common ways attackers get in — no exploit required, just a valid username and password bought or scraped from a criminal source. Worse, the victim rarely knows: credentials harvested by infostealer malware or exposed in a third-party breach circulate for months before they are used. Credential breach monitoring gives you early warning by continuously watching the places leaked credentials surface, so you can reset passwords and lock down accounts before anyone logs in as one of your users.

Blackfoot's breach and credential monitoring service continuously monitors for leaked credentials tied to your organisation's domains, drawing on infostealer malware logs, public breach dumps, criminal forums and Telegram channels, and dark-web search. Checks run twice daily, with alerts when new exposures are found.

How credential breach monitoring keeps you ahead

Every exposed credential is categorised — employee, third party, or customer — so you immediately understand who is affected and what the right response is. An employee credential means a password reset and a session review; a customer credential may mean proactive notification; a third-party exposure may mean a conversation with a supplier. Where the source contains plain-text credential detail, the service captures the username, password, source, and date, giving your team the specifics needed to confirm whether the credential is current and force a reset with confidence.

Findings are delivered through the Sentry platform alongside the rest of your exposure picture. We do not reset passwords or disable accounts on your behalf — that stays with your team — but the alerts arrive with the detail needed to act in minutes rather than days.

The service is priced per monitored domain and is available standalone or as a module of Sentry CTEM, Blackfoot's managed continuous threat exposure management programme. Many clients pair it with domain monitoring and security awareness training to reduce both the supply of leaked credentials and the phishing that harvests them.

Frequently asked questions

Straight answers to what prospective clients ask us most.

Where does the leaked credential data come from?

The service monitors infostealer malware logs, public breach dumps, criminal forums and Telegram channels, and dark-web sources. Infostealer coverage matters because these logs often contain fresh, working credentials harvested directly from infected devices — not just recycled historic breaches.

Will I see the actual leaked passwords?

Where the source contains plain-text detail, yes — the username, password, source, and date are captured and presented securely within Sentry. This lets your team confirm whether a credential is current and respond proportionately, rather than forcing blanket resets on every alert.

Does Blackfoot reset the affected accounts?

No — account resets and session reviews stay with your team, since they require access to your identity systems. The service's job is to make sure you know quickly and have the detail to act; alerts run twice daily with everything tracked in Sentry.

Can I buy breach and credential monitoring on its own?

Yes. It is priced per monitored domain and available standalone, or as a module of Sentry CTEM — so you can start with credential exposure and expand to the full continuous threat exposure management programme without re-onboarding.
