Keep software and devices updated
Close known security gaps in your phone, computer, browser, apps and connected devices.
Back up and restore your important files
Prepare for a lost phone, accidental deletion, hardware failure or ransomware with recoverable copies.
Secure home Wi-Fi and use public networks safely
Protect your router, separate connected devices and avoid traps on shared Wi-Fi.
Protect your phone and prepare for loss or theft
Secure apps, permissions and recovery before your phone is lost, borrowed or replaced.
Avoid malware and respond to suspicious activity
Recognise risky downloads, fake technical support and the steps to take when a device may be infected.
If a device is lost or stolen
Act quickly to lock a missing phone or laptop, protect your accounts and your SIM, and report it.
Use cyber cafés and shared computers safely
Sign in carefully on a cyber café or shared computer, leave no trace and protect your accounts afterwards.
Build a safer everyday setup
Your devices hold conversations, documents, photos and access to your money. A good starting point is a supported operating system, automatic updates, a strong screen lock and a backup you can restore.
Check your essentials
Install security updates for the operating system, browser, apps and home router.
Use a strong device PIN or password and a short automatic-lock period.
Enable device encryption and built-in security protection where available.
Install apps from official sources and review their permissions.
Keep important files in a protected backup separate from the device.
Set up official device-location and recovery tools before a device is lost.
Choose the right guide
Start with updates if you see security reminders. Set up backups before a failure. Review Wi-Fi settings when installing a router or moving house. Use the phone guide before lending, selling or replacing a device.
If a device may be compromised
Stop using it for banking or password changes. If malicious activity is suspected, disconnect it from networks and seek trusted support. Use a separate trusted device to protect accounts. For a work or school device, contact your IT team before wiping or reinstalling anything.
