New connections from Quick Assist, AnyDesk, TeamViewer, ScreenConnect and other common remote tools start blocked.
Xcelcor Guardian only allows access once somebody approves it, and by default that decision belongs to a person you trust.
The actual Guardian window on the protected PC. Note the only button: refuse. There is nothing here to approve with.

How it starts
A call, a text, a link : a different story every time. Every one of them ends in the same place.
Incoming call
“Microsoft Support”
“Your computer is sending us virus warnings. We need to fix it before it spreads to your bank.”
Incoming call Urgent
“Your Bank: Fraud Team”
“Someone is moving $2,400 out of your account right now. Stay on the line so we can stop it.”
Text message
“Refund Department”
“You were charged $399.99 for an annual renewal. Didn’t order it? Call now for a full refund.”
Link clicked
“Browser update required”
“Your browser is out of date. Install the update to keep watching this video.”
Behind the scenes, the “update” quietly installs a remote-access tool.
Every time, the same next stepA stranger tries to take control of your PC.
Guardian held the connection
Nothing connects until someone you trust approves it.
Whoever holds the Guardian account holds the key. Link a parent’s or an employee’s PC to your account and you approve for them; link your own and you approve for yourself. The difference isn’t convenience. It’s whether the person approving is the same person the scammer is talking to.
A parent, a partner, anyone whose PC you look after.
Survives a live scam call.
When there’s nobody else to hold the account.
Stops strangers and automated attempts. Not a determined live call.
| What it stops | Someone else approves | You approve |
|---|---|---|
| A stranger connecting while nobody is at the PC | Stopped | Stopped |
| Repeated automated attempts on the same address | Stopped | Stopped |
| Somebody controlling the PC approving their own connection | Stopped | Only if your email isn't open on that PC |
| A caller talking the person at the PC into approving | Stopped | Not reliably |
Approval never happens in the app on the protected PC. It only has a refuse button. Requests go to the account holder, by email and on this website.
Yes. That is the whole technique, and it is exactly why the decision cannot be hers.
When the PC is linked to your account, the person at its keyboard has no approve button at all. The request goes to you, with the address and the time, somewhere the caller has no way to reach. He can coach her for an hour and produce nothing.
What she sees while Dave is asked. There’s no approve button to talk her into, only Refuse.
One technique, two rooms. In both, it ends with somebody being asked for permission at the worst possible moment.
Twenty minutes on the phone. He knows which bank she uses. He has already talked her into installing the remote-support tool, because he has been kind and certain, and she doesn't want to make a fuss.
Now he needs permission to connect. On almost every computer, that permission is hers to give.
With Guardian it isn't. The request goes to you (address, tool, time), and nothing connects until you answer.
He says he's from the IT company you actually use. Right name, a ticket number, and he knows there's a payment run on Friday. She opens the remote-support tool, because that is precisely what she's been told to do when IT calls.
Now he needs permission to connect. Then he changes the account number on an invoice nobody will re-read.
With Guardian it isn't hers to give. The request goes to IT, or her manager, and every attempt is logged with the name of whoever decided.
The one question
Mom, did you ask someone to connect to your computer?
No? A man from Microsoft called about a virus. He said it was urgent.
Dave refused the connection · 2:16 pm
“Did you ask someone to connect?”
That is the entire test, and the scam has no answer for it.
After approval
Approval opens the door. Guardian keeps watching what happens next: inside the session, and around it.
Guardian is watching
Inside an approved session
The session you let in can still turn, and the technician somebody approved might not be one. Guardian ends it and tells you why, in plain language.
Around it: the call that wants remote access usually wants a payment page too
Programs that act like part of a scam, whatever they are called.
The fake warning pages and support numbers these calls start from.
Extra caution once a banking or payment page is open.
Your antivirus carries on doing its job. Guardian isn't trying to replace it.

Almost none of that was taken by defeating software. It was handed over, by someone who was asked nicely and said yes. That is the moment Guardian takes away.

Tech-support scams reported to the FBI in 2025 averaged more than $44,000 in losses per complaint. Family is $79.99 a year.
Not if her PC is linked to your account. She has no approve button. The request goes to you, by email and in your dashboard. The caller has no way to reach either. That is the reason approval sits with a second person rather than with whoever is being talked to.
Then nothing connects. Guardian refuses by default, so a missed request is a refused request. The failure costs you a phone call later; the alternative costs a lot more.
No. Her PC is linked to your Guardian account, so you approve its connections, not her, and not whoever is on the phone. The app on her PC only has a refuse button, so nobody at her keyboard, or controlling it remotely, can let a connection in.
No. Approve their connection once for a single session, or add their address to the whitelist so the next visit goes straight through. Guardian is not a ban on remote support.
When the same address has had a connection dropped five times, Guardian stops asking about it and blocks it outright. You can see and edit that list in your dashboard.
Guardian keeps watching the session. If an approved session starts transferring installers or reaching for administrator rights, Guardian can stop it and explain what happened. Approval gets someone through the door, not a free hand.
No. Guardian is designed to work alongside your existing security software. Antivirus judges files; Guardian judges who is allowed to connect.
No. Guardian does not record your screen. It sees connection attempts, approval decisions, and security-relevant activity inside an approved session.
No. They are asked to approve or refuse a connection, and they are told when something serious happened. They don't see your screen, messages, documents, passwords, or banking information.
The trial covers one PC for 14 days, starting when you link that PC to your account. Because we never took a card, it can’t turn into a surprise charge. When it ends, choose a plan to keep protection going, and to add more PCs.
Yes, and you do it yourself: in your account, open Payments and choose Manage billing. Guardian keeps working until the end of the period you paid for. Change your mind within 14 days of paying and we refund you in full, or within 30 days on an annual plan.
Yes. Start Family, send them an installation link, and their PC shows up in your dashboard after they install Guardian. Approval requests for that PC then come to you wherever you are.
