Remote-access lockdown stops strangers from using remote-control programs to get into your computers. If your office uses its own remote tool, such as TeamViewer, tell us so we can approve it.
¶ Why it matters
Remote-control programs let someone use a computer from far away. IT companies, us included, use them every day. Attackers use the same programs. Once they get in, they often install one so they can come back whenever they like, and because it is a normal program, antivirus often lets it run.
Huntress says rogue remote-access tools turn up in nearly 40% of its investigations. It also says blocking them could have prevented 32% of the incidents it saw this year (figures from Huntress, checked November 2026).
¶ What it does
Huntress RMM Guard is part of Huntress, the security service we already run on your computers. It uses the Huntress agent that is already installed, so there is nothing new to install.
- It lists every remote-control program on each computer.
- We check that list. Our own tools stay allowed, and so does any tool you tell us you use.
- Then it blocks any remote-control program we didn't approve, so an attacker can't use one to get in or come back.
It starts by only listing programs. Blocking comes later, after we have checked your list. Huntress includes RMM Guard during its early access.
¶ What you might notice
Day to day, nothing. There are no pop-ups and nothing to click, and your computers run the same.
You might notice something if your office uses its own remote tool, for example:
- TeamViewer, AnyDesk or Splashtop to work from home
- a tool a vendor uses to support your software or equipment, such as your practice management system or a copier
Once blocking is on, a tool we haven't approved won't start.
¶ Tell us about your remote tools
Email [email protected] with:
- the name of the program
- who uses it: your staff, or which vendor
- which computers it's on
We approve it for your company. If a tool you rely on stops working, open a ticket or call us, and we look at it straight away.
If someone calls saying they're from Rainier IT and asks you to install a remote-control program, hang up and call us back on (206) 593-8072. See How to tell it's really us.
