Modern phones have powerful self-defence built in. You just have to know how to trigger it.
Both iOS and Android have powerful lost-phone tools built in. Most people don't think to use them until hours later, by which point the damage may be done. Done within the first five minutes, the phone is effectively neutralised — useless to whoever has it, recoverable to you if it's been left somewhere.
On any other device (laptop, partner's phone, friend's phone), open iCloud.com/find (iPhone) or android.com/find (Android). Sign in. Select the missing phone. Tap 'Mark as Lost'. This instantly locks the phone, displays your contact number on the lock screen, and disables Apple Pay / Google Pay on it. Takes about 60 seconds.
Same panel — tap 'Play Sound' if you might have just dropped it nearby. It'll ring loudly even on silent. If you can see on the map that it's far from where you last had it (an unexpected suburb, on the move), assume it's been stolen and move to step 3. If it's at your house or the cafe you just left, retrieve it.
Telstra, Optus, Vodafone, Aldi Mobile, Boost — all have 24/7 lost-device lines. Suspend the SIM. This stops the thief from receiving your SMS — critical because SMS is often used as a second factor for password resets. Until the SIM is suspended, the thief can potentially reset your bank, email, and social passwords using your phone number.
Email is the master key — every other account can be reset via email. If your email is open on the phone (which it almost certainly is), the thief has full access. Change the password on a trusted device immediately. This kicks them out of the email app on the phone.
Once you're sure the phone is gone (couple of hours, no movement on the map, no response from anyone who might have found it), go back to iCloud/Android Find and tap 'Erase This Device'. The phone is wiped to factory state — useless to a thief, all your data is gone from it. Your iCloud / Google account backup is still intact for the next device.
Biometric (Face ID, fingerprint) is convenient but only works while you're holding the phone. The PIN is what really protects it when stolen. Use a 6-digit minimum (the 4-digit default is too easy to brute force). Don't use a birthday, anniversary, or 1234 / 0000 / 1111.
Lost phone is one of the most common credential-loss events. Tie it to the rest.

No deck, no pitch — walk your environment with a senior Australian practitioner. Confidential by default.
I built this business because I wanted to do Managed services properly — for a small number of clients, at a senior level, with the same person on the end of the phone every time. The work is too important and the stakes are too high for anything less.
Behind the formal qualifications: a Cyber Security degree from the University of the Sunshine Coast, currently working on my Master’s, plus a continuous stack of Microsoft, Acronis and Nerdio certifications — the ones that have to be renewed because the threats don’t stay still.
Behind the certifications: thirty years of doing the work. I cut my teeth in consulting, then went to Cisco on the team building the original iPhone — Cisco’s VoIP handset, the trademark Apple later acquired in the 2007 settlement. At TPG in 1999 I sold frame-relay networks when frame-relay was the cutting edge of business connectivity. I built and sold a Sydney-based MSP called Online IT before relocating to Perth.
Three decades of watching what’s actually changed and what hasn’t. The technology has changed almost beyond recognition. The principles haven’t. Identity first. Backup that has actually been tested. A senior practitioner who knows your environment. Calm in an incident. Honest answers when the answer is “no.”
That’s whedo.it. That’s the brief. That’s why long-tenure clients don’t leave.
