The block button is the last step of application control, not the first. Offices where blocking works without drama all share one thing: a short written policy that existed before the first application was ever stopped. Here is what that policy needs to say — and what happens in offices that skip it.
Application control fails socially long before it fails technically. An employee who discovers a block by surprise hears one message: IT does not trust me. The same block, announced a week earlier with reasons and an exception route, is heard as a company rule. The technology in both offices is identical — the policy paper is the difference. Write these four parts before you open the console.
Write categories, not app names: games, torrent and peer-to-peer clients, personal VPNs, unapproved remote-access tools, crypto miners, and tools with no business purpose. Categories survive next month's new game; a list of names does not. When discovery shows an app, you only have to answer one question — which category does it fall into?
This also protects you. An employee blocked under a published category has been treated by a rule. An employee blocked by name has been treated by a person, and they will argue with the person.
Every policy needs one sentence: exceptions are approved by this role, through this route, within this time. In the console that route is the user request feature; on paper it is a named approver and a promised reply time — one working day is a good promise. An exception process with no owner and no deadline is the same as having no exception process.
Decide in advance what a permanent exception looks like too: the app moves to an allowlist for that person's group, and the decision is recorded. Temporary needs get temporary, time-bound access — never a permanent hole opened in a hurry.
Send the policy to staff before the first strict deployment, with three things in it: what categories are blocked, why (security, licence risk, bandwidth, work time — say the real reason), and how to request an exception. Give a date. People accept rules they saw coming; they fight ambushes.
Expect the announcement itself to fix half the problem. Once staff know a discovery scan exists and a policy date is set, a good share of personal software quietly disappears on its own — no block event, no argument.
Software changes every month, so a policy written once and never read again quietly becomes wrong in both directions: new junk runs free, and a tool the office adopted officially stays blocked from an old decision. Put a quarterly review in the policy itself: read the unmanaged-apps report, re-check the block categories, and clear stale exceptions.
The review is also where false blocks get forgiven properly. If an app was blocked and later became part of someone's real job, the review moves it to the allowlist openly — instead of one admin quietly punching a permanent hole.
Every click shown live in the ManageEngine console — application groups, policy deployment and the audit-to-strict switch.

Categories — games, torrent clients, personal VPNs, unapproved remote tools — cover new arrivals automatically and make every blocking decision explainable in one line.
As a recorded exception, not a quiet favour. The request comes through the console, the named approver approves it, and the app is allowlisted for that department's group only. Everyone else stays blocked, the decision is in the audit log, and the quarterly review can revisit it. That is a policy working; a whispered permanent unblock is a policy leaking.
Yes, and the policy should say so. The appeal is simply the exception request with a reason attached. If the reason is good — the app is part of real work — the app moves to the allowlist for that group. A blocking system with no appeal route does not produce compliance; it produces personal laptops and phone hotspots, which you cannot manage at all.
