FAQ · Checking for a Data Breach
You can check whether your email address has appeared in a known data breach using the free website Have I Been Pwned, which searches public breach records and reports instantly whether your address has been exposed.
What a breach listing actually means
Have I Been Pwned aggregates data from publicly known breaches of other websites and services — not from Fresh Mango or any specific business system. A match means your email address, and potentially an associated password, appeared in a breach of a third-party service you registered with, such as an online retailer or forum.
A match does not mean your current business systems have been compromised, but it does mean any password reused between that breached service and your business accounts should be treated as exposed.
What to do if your address has been breached
- Change the password on any account still using the breached password, prioritising email and financial accounts.
- Never reuse the same password across multiple services — a password manager removes the temptation to do so.
- Enable multi-factor authentication wherever it is offered, so a breached password alone is not enough to gain access.
- If the breached address is a company email account, tell your IT provider so wider monitoring can be applied.
Frequently asked questions
Is Have I Been Pwned safe and free to use?
Yes, it is a well-established, free, non-commercial service that only requires you to enter an email address; it does not ask for a password.
What if my email address has been breached multiple times?
Each listing is a separate exposure event. Treat every one as a reason to check for password reuse, and consider that your email address itself is now more visible to targeted phishing attempts.
Can Fresh Mango monitor this for our whole company?
Yes. Complete Cyber Security offers ongoing monitoring for company-wide domain and credential exposure, rather than checking addresses one at a time.
