"Want to protect your device against browsing threats? With browser
isolation, you can sandbox your web activities to protect your device
against cyberattacks.

What is browser isolation? Browser isolation (also called web
isolation) is an online security tool that keeps your web browsing
activity segregated from your device and local network. Instead of
loading webpages (and any malicious code they might try to execute,
such as JavaScript) directly on your computer, browser isolation loads
them in a protected environment: either a sandbox (such as a virtual
machine) or a remote browsing session hosted online and accessed via
an interactive video feed.

Browser isolation prevents malicious programs from accessing your
system. It also gives you the freedom to browse the web without
exposing your IP address or device fingerprint data, which can be used
to identify you, track, and engage in profiling."

Is that the same as Private Windows in Firefox, aka Site Isolation???

If you share a computer with other people or if you want to limit how
much data websites can collect about you, you can use private browsing
mode in Firefox. Private browsing erases the digital tracks you leave
behind when you browse online rCo think of them like footprints through
the woods.
What does private browsing do?

Private browsing mode opens a new browser window. When you close the
last private browsing window, your browsing history and any tracking
cookies from websites you visited will be erased. Firefox Pro Tip:
DonrCOt forget to close all your private browsing windows when yourCOre
done!


What private browsing doesnrCOt do

Private browsing mode will not delete any new bookmarks you make from
a private browsing window, or protect you from malware or viruses. It
also doesnrCOt prevent the websites you visit from seeing where you are physically located or stop your internet service provider from logging
what you do. YourCOll need a trustworthy VPN for that.

Toolwiz Time Freeze protects you from *anything* sticking to your
disk after a reboot.

Since the referenced article points via affiliation links to IPVanish
who is NOT a provider of free VPN services, I removed the following

"Browser isolation"
They're trying to confuse the reader that something new is offered. All they're talking about is using a VPN. If you use their links to go to a
VPN site (they're promoting IPVanish), they get a commission on a sale.
Notice their link to IPVanish isn't just https://www.ipvanish.com/, but
to that domain along with a huge argument to identify you came from
their website. They're also lying to you. The protections they claim
you get are not afforded by using a VPN. They're pushing IPVanish which
offers VPN services. If you want IPvanish's secure browser feature, you
pay an extra $2/month above the VPN subscription. I have yet to find at ipvanish.com any description of just how their secure browser works. My
guess is it a reduced virtual host similar to how you can rent virtual
hosts at Azure: you'll use your local web browser to connect to their
virtual host to operate the web browser there to connect to a website.
But that's just a guess. Again, I didn't find anything at IPvanish
description just what is their secure browser (versus just another web
browser ran locally claiming to be more secure), or how it works, or how
you use it.

A VPN will let you circumvent geofencing, but it will not overcome
blocks at a website that has blacklisted VPN or Tor connections. The
exit nodes for VPNs and Tor have been mapped, and websites can use those
as blacklists to block access to anyone visiting the website from one of
those exit nodes.

It was discontinued. It operated as a virtual drive. While active, all
disk I/O went to the virtual drive instead of to the real drive. When
the computer was restarted, the old virtual drive was gone, a new
virtual drive got created, and you started over with a fresh virtual
drive. If you got infected with malware, it could act as a stacked I/O
driver which could still get at the real drive. Also, as I recall, Time
Freeze only protected the OS drive (normally C:), not any other drives,
so you could end up depositing malware on the other drives.

I tried it for a few months, but decided to instead rely on image
backups to restore the state of my drives. There were disk utilities
that ran afoul of Time Freeze's virtualizing the OS partition. Some
games would recognize the drive was virtualized, and their protection
refused to let you play the game. I use Macrium Reflect, but also paid
to get its Image Guardian feature which is a kernel-mode protection to
block any process other than Macrium from accessing the backup files for
read, write, rename, or remove. Not only protects against malicious
access, like ransomware, but also accidental access. I once tried to
move the backup files, got blocked by Image Guardian, had to disable it,
then move the files, and reenabled Image Guardian.

There were other attempts at virtualizing the drive, like Comodo's Time Machine, but that was so flaky that users reported losing everything on
the drive, plus it didn't protect its snapshot files. Other
alternatives are Faronics' Deep Freeze, Reboot Restore RX, Rollback RX, Shadow<something>, and others. A few were free, or had "home" free
versions, but most were payware, especially the more stable choices.
Even Microsoft had a similar tool, Steady State, but dropped it.

Points to IPvanish using affiliation links, so they get a commission on
any sales, and IPvanish has no free service tier.

Then Marcus wanders off to discuss Toolwiz Time Freeze. Is this the
same guy that periodically shows up trying to promote this deadware?

For clarification...

Hiding own IP address is only possible using VPN or transparent proxy.
Non-VM sandbox, VM, and browser alone can not do it.

Hiding own actual device fingerprint is only possible using web browser (if it's only for browsing the web), or using VM. VPN and non-VM sandbox can not
do it.

So, with the given list of softwares, it will require at least two of them
to cover both cases. Not just one.
