Platforms, licences and device counts
A subscription is sold with a number attached — so many devices, so many users — and the number is where households most often find the product does not match what they thought they bought. This page covers how licences are counted, what each platform's application can actually do, and the arithmetic worth doing before purchase rather than after.
Quick answer
Count every device in the household that will be covered, including the ones belonging to people who will never open the app. Then check that the plan's application for each of those platforms includes the features that motivated the purchase, because feature sets differ by platform more than by plan. A licence count that is tight on the day of purchase will be short within a year.
What counts as a device
Vendors define a device as one installation of the software on one machine, and the count is usually enforced by the account rather than by the licence key. Three details decide whether a number is generous or tight.
- Whether a phone counts the same as a laptop. In most consumer plans it does: a five-device plan covering two laptops and three phones is fully allocated, and the next tablet needs a place.
- Whether a seat can be moved. Reassigning a licence from a replaced laptop to a new one is ordinarily done by removing the old device from the account. Where that is not straightforward, a household replacing a phone loses a slot.
- Whether household members can be separate users. Some plans are a pool of device slots managed by one person; others create individual accounts under one subscription. The second arrangement matters when the household includes adults who do not want a parent or partner administering their device.
Australian households are typically mixed. A common shape — two working adults with a laptop and a phone each, one or two children with a phone and a shared tablet, and a desktop or a smart TV in the living room — reaches seven or eight countable devices before anyone has thought about it. Plans sold in small increments run out against that shape quickly.
What each platform's application can do
The same product name means different things on different platforms, because the operating systems permit different things. The table below describes the general position across the category rather than any one vendor's plan; the specifics always belong to the vendor's documentation.
| Platform | File scanning | Web and phishing filtering | Bundled extras that usually work | Main limitation |
|---|---|---|---|---|
| Windows | Full, including real-time protection | Yes, in-browser and system-level | Password manager, VPN, firewall controls, cleanup tools | None specific — this is the reference platform |
| macOS | Full | Yes | Password manager, VPN, web filtering | Windows-only utilities are usually absent from the Mac build |
| Android | Application scanning | Yes | VPN, password manager, app permission review, anti-theft tools | What the app can see of other apps is limited by the operating system |
| iOS and iPadOS | Not in the conventional sense | Yes, via a filtering profile or VPN mechanism | VPN, password manager, breach monitoring | No device scanning is possible; the app does other work under the same name |
| Linux desktop | Where the vendor offers a build | Usually not | Rarely anything beyond scanning | Support varies by distribution and is thinner than on Windows |
The iOS row is the one that causes disputes after purchase. A household that bought a five-device plan expecting equivalent protection on two iPhones is not being denied a feature by the vendor; the platform does not permit it. Understanding that before purchase changes what the plan is being bought for — on iPhones, realistically, web filtering and a password manager.
Who administers the account, and what they can see
A household plan concentrates administrative control in whoever set it up. That is convenient and it has consequences that are easier to settle at the start than later. Depending on the product, the administrator may be able to see which devices are active, when each last checked in, what was blocked on them and, where parental controls are switched on, a summary of activity. Between a parent and a young child that is the point of the feature. Between adults sharing a subscription, or a parent and a teenager, it is a different matter, and worth an explicit conversation rather than a discovery.
The eSafety Commissioner's advice for parents treats monitoring as one option among several and is candid that heavy-handed surveillance has costs in trust and in what a young person is willing to report. Where a household's situation involves family or domestic violence, device monitoring carries risks in the opposite direction, and eSafety publishes specific guidance that should be read before any monitoring tool is installed on a shared or gifted device.
The practical point for a comparison: if the household wants coverage without one person supervising everyone, look for a plan that issues separate accounts under one subscription rather than a pool of slots administered centrally. That structural difference matters more than the device number.
Devices a subscription does not cover
Smart televisions, streaming boxes, game consoles, printers, cameras, doorbells and other connected household equipment cannot run a consumer security application, and they are the devices most likely to be running software the household cannot update. The realistic measures are different in kind: change any default password before the device joins the network, apply whatever firmware updates the manufacturer provides, and switch off remote access features that are not being used. The ACSC publishes guidance on securing devices that covers this ground without reference to any product.
The home router deserves a separate mention, because it is the one device every household has and almost nobody administers. Its firmware updates, its administrative password and whether its management interface is reachable from outside the home are worth checking once, and rechecking when the internet provider replaces the hardware.
The arithmetic worth doing before purchase
- List every device that will be covered, including devices belonging to household members who will not participate in setting it up.
- Add the replacements expected within the subscription term. A phone replaced mid-term needs a slot, even briefly, alongside the one it replaces.
- Separate the list by platform, then check the plan's feature list for each platform rather than for the plan as a whole.
- Identify which feature the purchase is actually for. If it is the password manager, confirm it runs on every platform in the list, including the ones that only get the reduced application.
- Check what happens at the end of the term to anything stored in the product — vault contents in particular — and whether it can be exported in a standard format.
- Compare the total against what the household already pays for standalone tools. Consolidation is worth something; paying twice for the same function is not.
The product covered in this library
TotalAV lists applications for Windows, macOS and Linux desktops, for Android and iOS phones, and for iOS, Android and Windows tablets, and is sold to customers in Australia. That is the extent of what this site states about its platform support, because licence counts, per-platform feature sets and plan inclusions are set by the vendor and change between plans and over time. They are on the vendor's own pages, which is where a household should check them against the list it has just written.
Paid placement: Prospect Works receives commission from the vendor's affiliate program on subscriptions that start with this link, and the reader's price is the vendor's standard price either way. Check the plan's own device count and platform list before subscribing.
