Worried About Ransomware or Virus Attacks?

Most cyberattacks succeed for one simple reason: malicious software is allowed to run.

We offer a new, simple, and highly effective solution:

Don’t Let Them Run

If ransomware or a virus cannot execute, it cannot cause harm. Our approach configures the operating system to allow only authorized programs to run — everything else is blocked automatically.

How It Works

We use a whitelist that includes all approved executable programs, along with the libraries and folders they depend on. The operating system checks this whitelist before running anything.

During normal operation, this whitelist — and all its associated libraries and folders — is read‑only. Not even admin, su, sudo, or root users can modify it.

To make changes, the system must be booted into a secure maintenance mode that hackers cannot access. This prevents any unauthorized modification by online attackers.

What This Achieves

• Blocks all ransomware and viruses — including brand‑new variants that antivirus tools haven’t detected.

• Eliminates the need for antivirus software entirely.

• Prevents hackers who gain access from running unauthorized programs.

• Stops insider threats from executing harmful code.

• Simplifies maintenance: the whitelist tracks folder paths, not individual executables.

• Requires no signature updates — changes occur only when software is installed or removed.

• Creates an immutable system by including all kernel‑level executables.

• Neutralizes most vulnerabilities, because exploitation requires a program to run — and unauthorized programs cannot run.

Available Now

We offer a fully functional product, FunDo Version 1, based on Ubuntu 24.04. We can also customize solutions for any Linux‑based open‑source operating system.​​
