A great tool can still be the wrong answer. On one PC the tray prompts are a feature; across an office they are fifty people making security policy one click at a time. Here is the honest split.
Nothing here is an attack on the tool — on a single machine it is one of the most useful firewall utilities on Windows. The office question is about where decisions live. A prompt asks the nearest person. A policy asks the organisation once. When PCs multiply, that difference stops being philosophy and becomes the whole game.
On a single PC, or a technician's own machine, this tool is excellent: prompts you can read, a log you can search, rules you can fix in seconds. Nothing in this page argues otherwise. The office question is different: what happens when the same decision must exist on fifty machines at once?
Prompts delegate security decisions to whoever is sitting at the keyboard — and in an office, that person is busy, non-technical, and will click allow to make the box go away. Fifty PCs also means fifty slightly different rulesets, fifty logs nobody centralises, and no answer to the auditor's simple question: show me the firewall policy. A per-PC tool cannot produce a per-company answer.
On a Windows domain, firewall rules are a Group Policy setting: written once by the admin, applied to every PC in the OU, refreshed automatically, and reportable. Users cannot approve their own exceptions because the prompts were never the mechanism. Windows Firewall with Advanced Security was designed for exactly this — the same engine the tray tool manages, driven centrally instead of by hand.
Real offices often land in the middle: Group Policy owns the fleet's baseline, and the tray tool lives on the IT staff's own machines and on special standalone PCs — a lab box, a reception machine not on the domain — where its prompts and log are exactly the right size of solution. Chosen deliberately like that, the tool is an asset. Installed everywhere as a substitute for policy, it is fifty small exceptions waiting to be discovered.
Between one PC and a domain there is a real middle case: five or six machines, no server, one careful owner. There, the honest pattern is one reference PC configured properly with Medium Filtering, its ruleset exported, and that same file imported on the others — policy by photocopy. It does not refresh itself and it drifts over time, so re-export and re-apply it on a schedule. It is not Group Policy, but it is one decision applied everywhere, which is most of what policy is for.
Profiles, prompts and rules — the whole Firewall Control walkthrough is in the video.

For a handful of PCs it can be a practical stopgap — one careful person setting Medium Filtering and reviewing logs beats nothing. But treat it as a stopgap: the moment the office grows, the lack of central rules becomes the risk.
Yes — it is a full enterprise-grade firewall engine, which is why it can be driven by Group Policy in the first place. The office question was never the engine's quality; it is whether rules are decided once, centrally, or fifty times at fifty keyboards.
