Detecting a data breach can be difficult, but there are a few key signs to watch for. Unexpected password resets, unrecognised logins, unusual network activity, and missing files can all indicate that your system has been compromised.

Businesses can use monitoring tools that alert administrators to suspicious activity, such as multiple failed login attempts or unauthorised file transfers. Edmondson’s provides proactive system monitoring to detect these anomalies before they cause damage.

You can also check whether your email addresses or credentials have appeared in known breaches using trusted websites like haveibeenpwned.com. If your details appear there, it’s essential to reset passwords immediately and enable multi-factor authentication.

If you suspect a breach, isolate affected systems, inform your IT provider, and change all relevant passwords. You may also need to notify the Information Commissioner’s Office (ICO) if personal data has been exposed.
