Security software for every computer

We look after your computers

We block attacks, keep every machine up to date, and back up your files. Install the app once — most problems get fixed before you hear about them.

Built and staffed in the United States

How it works

Three steps, then it runs itself

No server to set up and nothing to check every morning.

Install the app

A few minutes per computer. It works on Windows, Mac, and Linux.

We keep an eye on things

Threats, updates, disk space, and backups — checked around the clock.

You are never stuck

Questions about the app are always free. Want a technician to fix the computer itself? Add that on.

What we do

What we watch for you

One app on every computer, quietly doing the work.

Malware being stopped on a computer before it can spread

We stop attacks

Malware and ransomware get blocked before they can do damage.

A fake invoice email caught and blocked before it reaches the inbox

We keep scam emails out

Fake invoices and phishing links get caught before you see them.

Needs a business mailbox on your own domain. Why

A file scrambled by ransomware being put back the way it was

We keep your files safe

If ransomware hits, we put your files back the way they were.

Apps being kept up to date and a disk being tidied

We keep everything updated

Your apps stay current and your computer stays tidy, on its own.

A scam website being blocked before the page loads

We block dangerous sites

Fake shops, fake logins, and infected pages never open.

A list of fixes, each with the time, what changed, and which computer

We show our work

Every fix is written down: what changed, when, and on which computer.

Why it works better

Not the antivirus you grew up with

Older tools only recognize threats someone has already cataloged, and they still need a person to clean up. Ours watches how software behaves and acts on its own.

The old way

  • Matches a list of threats already known
  • Brand-new attacks get through until the list catches up
  • Tells you something is wrong, then waits for you
  • A separate tool for updates, and another for backups

CloudCastle

  • Watches how programs behave, so new attacks stand out
  • Stops ransomware while it runs and puts your files back
  • Fixes what it can itself, and writes down what it changed
  • Updates, backups, and security in one app

Talking to a human

Two kinds of help, and they are priced differently

Worth knowing before you pick a plan: help with CloudCastle itself comes with every plan. Having a technician fix your computer for you is an add-on.

Included with every plan

Help with CloudCastle

Trouble installing the app, or something in it not working right? That is product support, and it comes with any active plan at no extra cost. Email us and a real person answers.

Add-on — not in the base price

Help with your computer

Printer offline, email broken, a new laptop to set up? A technician in the US can take control and fix it while you watch. That is on-demand tech support, part of our managed service — you add it to a plan, and it is quoted separately.

Worked 10 AM–6 PM Central, Monday through Friday. You pick the slot and we confirm it by email.

Either way, nobody connects to your computer until you say yes, you can watch the whole session, and it is written down afterward.

Managed for you

Want CloudCastle to manage your systems?

You do not have to run any of this yourself. An American technician can watch your computers for you and handle whatever the AI cannot finish — the machine that needs rebuilding, the fix that needs a judgment call, the person who wants someone to talk to.

An add-on to any plan, quoted separately — or we introduce you to a partner provider who can take you on. Worked 10 AM–6 PM Central, Monday through Friday. Help with CloudCastle itself is always included.
