What does Guardian actually do?
It refuses every new remote connection to a PC until the person who holds its Guardian account approves it. That can be someone you trust, who has linked your PC to their account, or you, for your own PC — and those aren’t equally strong, because only one of them is somebody the caller isn’t talking to. See how it works.
Who should hold the account — me, or someone I trust?
Someone else holding it is the strongest, and what Guardian is built for. A caller who controls your PC and has you on the phone has no route to a different person at all.
Holding it yourself is the convenience option: you approve by email link or in the dashboard. That stops strangers and automated attempts. It doesn’t reliably stop you being talked round, because you are the one on the call — and if your mailbox is signed in on the protected PC, somebody controlling that PC could open the request and approve it themselves. Read approvals on your phone, and hold the account yourself only when there’s nobody to ask.
Is Guardian an antivirus?
No. Keep your antivirus. It judges whether files are malicious; Guardian judges whether anybody agreed to let this person connect. A remote-support tool a scammer talks someone into installing is usually not malware, which is why a virus scan stays quiet.
A scammer is on the phone with my parent. Can't they talk them into approving it?
Not if their PC is linked to your account. The person at the PC has no approve button — the request goes to you, by email and in your dashboard, neither of which the caller can reach.
Can I still use TeamViewer, AnyDesk, or my IT person?
Yes. Guardian is not a ban on remote support. Approve a session once, or whitelist that address so future connections go straight through. Business deployments can whitelist the tools and addresses their support desk uses.
What if nobody answers the approval request?
Nothing connects. Guardian fails closed, so an unanswered request is a refused one.
Can a caller talk me into approving my own connection?
If you hold the account for your own PC, they can try. You are the one on the call, and the approval is yours to give. That is the honest limit of any approval you give yourself. Read the request on your phone, check the address and the tool, and refuse if you are not sure. If being talked round is the thing you are worried about, have someone you trust hold the account and link your PC to it instead. That is exactly what it is for.
What are Blocked IPs?
An address whose connections have been dropped five times is blocked outright and stops generating prompts. The list is visible and editable in your dashboard, so anything blocked by mistake can be released.
What happens after I approve a connection?
Guardian keeps watching that session. If it starts transferring installers or reaching for administrator rights, Guardian can end it and tell you what happened in plain language, with technical details if you open them.
Can Guardian see my screen? Can a Trusted Guardian?
No, and no. There is no continuous screen recording. A Trusted Guardian is asked to approve or refuse a connection and is told when something serious happened — not given your documents, messages, passwords, or banking session.
What happens after the trial, and can I cancel?
The trial covers one PC for 14 days, starting when you link it to your account. There’s no card on file, so it cannot bill you. You can cancel a paid plan yourself, at any time, in your account under Payments. Change your mind within 14 days of paying and we refund you in full, or within 30 days on an annual plan.
Can I protect a parent who lives somewhere else?
Yes. Send an installation link. Their PC appears in your dashboard after they install, and approval requests for it come to you wherever you are.
