First off, make sure you have ownership over a genuine account for your self/business on all the major platforms - whether you use it or not. This makes it harder to imporsonate you in the first instance. Second, include a notice on each that THIS is the only real acocunt for you/your business ... no side-accounts. As for harrassment, it really depends on what's happening.

Social media fraud?
Yes, with some limitations. Check here for Apple's latest: https://support.apple.com/en-us/HT212227. But remember, the AirTag is not GPS-enabled. It only sends location updates to its owner every few mintues, and only if it can find an iOS device within bluetooth range that has Find My network connection enabled.

AirTag tracking?
Maybe. But you're probably not worth the effort, unless you have high-value data in your home or you otherwise have a highly motivated bad actor (e.g. ex-significant other, celebrity stalker, etc.). Even if a bad actor get's in to your network, it's not like the movies where they see your laptop's screen. But if you have wi-fi door locks or wi-fi cameras ... please DO NOT just use factory settings / security protocols.

Wi-fi snooping?
Anything you purchased new after 2018 - Android or iOS - should be fine, as long as you have a PIN enabled; try to use a 6-digit alphanumeric PIN. One exception is if your phone uses external media, like an SD card.

Stolen smart phone?
Tracking takes many forms. Some passive (like looking at your social media posts) and some active (like dropping an AirTag in your pocket). To start, make sure your mobile devices do not use an account where the email is known or tied to a potential bad actor (significant other or friendly relative). If you have an iOS device, you can also use Safety Check (pull down on the Home screen and search for "Safety Check"). If sufficiently motivated or financed, tracking efforts can be more sophisticated and require a site vist by our people.

Is my ex stalking me?
That's why you need to hire us; the earlier the better.

You didn't know?

Personal Digital Security

Whether your income is tied to your online persona(s) or you (and your family) just spend a lot of time (and therefore have a lot of data) online, you are now more likely to be the victim of a cyber-crime than a physical crime. Law enforcement response to cyber-crime is often non-existent, leaving most victims to fend for themselves. This is because cyber-crimes cross jurisdictional boundaries, generate non-traditional types of evidence which most law enforcement agencies are largely decades behind understanding, and can be perpetrated or funded by state actors (foreign governments). So it's up to you — and us — to secure your digital assets!

Here are some questions you might have. We hope our responses give you a sense of our competence.
