    What dark web monitoring is

    It is the continuous surveillance of breaches and criminal markets to detect your company's credentials already exposed before someone uses them. Stolen credentials are the raw material of initial access: they circulate on the dark web, get sold in batches and are tested automatically against dozens of services. The full definition lives in the glossary; this page explains how Fensivo does it.

    More than 90 percent of successful cyberattacks start with a phishing email (CISA). An exposed credential makes that email better targeted, or unnecessary altogether.

    What it watches

    Two sources, one daily scan, one response

    When a credential from your domain appears, the system acts. It does not depend on anyone checking.

    1. 680+ public breach databasesDaily scanning of published dumps, looking for your organization's emails and domains.
    2. The dark web, where trading happensRepositories, channels and forums where stolen credentials are posted and sold, including what infostealers exfiltrate.
    3. Match with your domainThe email of someone on your team appears in a source.
    4. Automatic responseAlert, notice with a deadline, training if it applies, and a log entry.

    How those credentials get there, from an infostealer to a third-party breach, is explained on the blog: dark web monitoring for companies, what it is and how to know.

    Alerts and response

    From months to hours

    Without monitoringthe gap is measured in months
    With Fensivohours

    In that time the credential has already been tried everywhere. And nobody waits on the other side: according to Mandiant M-Trends 2026, the handoff time between initial access and the actor executing the attack collapsed from over 8 hours in 2022 to 22 seconds in 2025.

    Value from day one

    The initial exposure report arrives in 48 hours and tells you which of your team's credentials are already circulating, without waiting for behavioral data.

    Closed loop

    Integrated into the human risk management cycle

    Monitoring without a cycle is an alert inbox. Inside the cycle, each detection improves the test and the training that follow.

    1. Leaked credentialSomeone with an exposed credential is a likelier target.
    2. That person's simulationThe next phishing simulation is chosen with that context.
    3. Risk scoreThe result adjusts their score and steers the training.

    This is how the phishing simulation works and how the risk score is calculated. The category guide is at human risk management and the complete platform, with all four engines, at the product page.
