Privacy

Your private browser is not so private after all


Authored by a Symantec employee

 

You probably expect your private browser to be private. It’s not.

So-called private browsers are a standard feature in web browsers. They come with private-sounding names like Private Browsing, Private Tab, and Private Window. Using a private browsing mode can help you to do a lot of things, but maintaining total privacy isn’t one of them.

Your device may not be secure.

Public Wi-Fi isn’t always safe. Without the right protection, your personal information could become public. Protect yourself with Norton Secure VPN. It encrypts the personal information you send and receive on public Wi-Fi to help keep it private wherever you want to log on.

Help protect your information with Norton Secure VPN.

That doesn’t mean they’re not useful.

Here are some things you might want to know about private browsers.

Also, it’s smart to understand what a private browser doesn’t do. For instance, do you know that your data can still be accessed in most browsers when you browse in private mode?
Chances are, you want privacy and safety when you go online. So how do you get it?

Hint: Think VPN.

What is private browsing?

Web browsers come with features that help them store data about the users’ activities to make revisits easy.

How? When a browser caches web-based content like usernames, passwords, and images, it speeds up the login process. That can be convenient. But sometimes you might not want that convenience. Storing that data can compromise your privacy.

Enter private browsing.

For example, Google’s Incognito mode wasn’t created to mask or hide your identity. It was primarily designed to make it easy to use shared computers.1

Here’s how private browsing solved a problem. Multiple users would store many different cookies in the devices. That would create chaos when browsing, with information popping up that might be helpful to another user, but not to you.

When you use a private browser, all browsing history, search history, and cookies get automatically erased. A private browser also limits web tracking — meaning, websites have trouble keeping tabs on you. Some private browsers even help hide your location.

Why Incognito mode isn’t truly private

Some web browsers that offer private browsing come with a statement that explains why going private is not completely private. The goal of private browsing is to prevent information from being automatically stored in your device, like browsing histories or downloaded cookies. Though in some instances, files that have been downloaded or bookmarked may still be saved. Then, the private browsing session expires only when the browser window is closed.

The issue remains: your activity may still be visible to the Internet service provider, as well as to the organization that provides the Internet connection, such as a school, college, or company. Also, the websites you visit may be able to view the session. They may not be able to save anything in your computer.

Is a private browser safe? 

As with any other browsing session, private mode may be safe if your device is fortified with an up-to-date security suite and runs the latest operating system. If not? Cyber snoops or hackers may be able to view your session.

Going private does not protect you from cybercriminals. Always be sure to use a robust security suite in all devices before going online — private browsing or not.

Why go incognito while browsing

There are a lot of good reasons to go private while browsing, including these:

  • Using multiple email accounts. You can open a tab in private mode and log into multiple email accounts without the hassle of logging off from one account and logging into another.
  • Using a shared computer or a computer that’s not yours. Sometimes you’re away from your own device and have to use a Mac, PC, or another device that does not belong to you. A private browser should prevent your passwords, search history, and browsing history from being saved on that device.
  • Shopping for gifts. Birthdays, holidays, or any occasion — if you’re shopping for a gift for your significant other on your shared computer, make sure you go private. The last thing you want is an overenthusiastic browser sharing your gift ideas and spoiling your surprise.
  • Researching “delicate” topics. Sometimes you might need to research topics that you’d rather not have to enter into that search box. Researchers, writers, college students, and others have had to search for terms that were out of their comfort zone. A private browser may save some embarrassment.
  • Booking travel online. Whether you’re looking for cheap airfares or hotel bookings, a private browser may help. With web tracking disabled, airlines and hotels can’t learn too much about your need or desperation to get desired dates and bookings. This may prevent them from altering fares based on your search history.

What’s the difference between a private browser and a secure browser?

A private browser prevents websites from installing cookies on your device. A secure browser makes it difficult for hackers to access your device.

A lot of secure browsers have been created in recent years. These provide a layer of security that can’t be found in a private browser.

Even so, most secure browsers are open source, and there’s no guarantee your browsing history remains entirely private.

Safety, privacy, or both?

It’s an easy choice. You probably want safety and privacy. A private browser likely can’t give you both. A secure browser may not be able to either. What to do?

That’s where a virtual private network comes in. A VPN is a great place to start if you’re looking for a combination of security and privacy. Think of a VPN as a privacy manager browser.

A VPN can provide anonymity and security when you’re online, in part by hiding your IP address and encrypting your Internet traffic.

In short, it does what you wish your private browser did.

A security suite that helps protect your devices.

Free security software just doesn’t have the resources to keep up with new threats as they emerge. That’s why you need a multi-layered defense to security. Meet Norton Security Premium — protection for up to 10 of your devices.
