Detection asks whether something looks dangerous. Allowlisting asks a much simpler question: was this approved. A reception machine needs its clinical client, a browser, something to drive the scanner, and very little besides. Everything outside that short list can be refused by default rather than judged on the fly, and a refusal is far more reliable than a judgement.
A detection engine is making a probability judgement about behavior. Most of the time it is right. Allowlisting is not making a judgement at all. If the software was not approved for this machine, it does not start, and it does not matter whether it is brand new, cleverly packed, or arrived inside a document.
That is a strong control and it comes with a real cost: somebody has to maintain the list of approved software. The line on this page includes that work. Elevation requests and approvals are handled by the team at Fortify 24x7, continuously, rather than landing in a practice manager inbox.
Approving an application is not the same as trusting it with everything. Ringfencing sets out which other programs an approved application may launch, which files it may reach, and where it may send data. A spreadsheet application is allowed to be a spreadsheet application without also being a route to a scripting engine and out to the internet.
In a practice this matters most for the software that opens attachments all day: the office suite, the PDF reader, the browser. Those are approved, necessary, and the most common starting point for something unpleasant.
Each figure here is read live out of billing. Whatever you pick sits waiting on the side panel while you keep reading down the page.
Software that was approved runs. Anything else is turned away, and the approval work is carried by our team rather than by whoever happens to be sitting at reception. A learning period assembles the opening list from what the practice genuinely uses, so nobody writes it from memory.

Allowlisting is the strongest control in this catalog and the one most often abandoned during week one. Here is what it does not do.
