What to do when something looks suspicious
Stop interacting with the item, preserve the evidence and contact the person or organisation through a separately verified channel.
A SecurCheck score supports a decision but is not a certification or an absolute guarantee. New, private or unavailable signals may remain unobservable.
Data breaches: anticipate risks to your business accounts
A breach at a third-party service can expose employees’ work email addresses and, depending on the incident, passwords or other personal information. Attackers may use exposed credentials for credential stuffing: testing reused login details on other services, including business applications. Even without an exposed password, an email address can be used for targeted phishing.
Give your teams a practical starting point for responding to data breaches. Used as a compromised email checker, SecurCheck helps employees check whether their email address has appeared in a breach, identify affected services when the information is available and prioritise account protection. The report supports password changes on affected services, stronger authentication and reporting to IT.
An address appearing in a breach does not prove that its mailbox is compromised. No result does not rule out a recent, private or unindexed incident. Never submit a password or MFA code to check an account; contact your IT team if you see suspicious activity.
