DFNDR Security Review

Sometimes people think that they only need virus protection for their computers. They forget that the handheld mobile device they use every day is also a computer, and it needs protection! With the high number of cyber-attacks that occur daily, having an antivirus solution on your smartphone is important and should be taken seriously.

DFNDR Security Review

We are going to take a look at DFNDR (pronounced Defender) Security and determine whether the Android antivirus is reliable. Oh, and did we mention it’s free?  So, Android users, listen up!

What is DFNDR Security?

PSafe is the company that developed DFNDR Security for Android users. The company originated in 2010 in Brazil but is currently headquartered in San Francisco, California.

DFNDR Security is an antivirus solution for Android users with lots of features. Check these out:

  • Real-time antivirus
  • Manual virus scanning
  • Auto virus scanning
  • Anti-spyware
  • Chat/IM protection
  • VPN service
  • Smartphone optimizer
  • Device tune-up
  • Safe browser
  • Ticket support

Is the DFNDR App Safe?

The DFNDR app is one of the most widely downloaded apps, with more than 200 million installations around the world. As a free app, you may be wondering if it is safe. While it is 100% free, there are ads that come along with it (of course), which may be annoying.

You can upgrade to a premium package to avoid the ads if you wish. We will discuss the premium package in a bit. Overall, DFNDR is completely safe to use.

Reliability and Security

Many independent testing companies have tested DFNDR Security in terms of malware detection and removal. The lab results of the AV-Test were great: the antivirus scored 99.9% on detecting and removing malware.

One of the most important tools of DFNDR is the Security Scan, which scans all the installed apps on your device for viruses and spam. The third-party test results prove that the Security Scan is effective.

You can also use the Full Virus Scan which will scan your entire device, including all your files. This scan takes longer than the quick scan, but it is thorough. The Cleanup App is a great tool, too. It clears all the caches to give your device more space and boost its performance.

Security Tools

DFNDR has many security tools to offer its users. Intruder Alert captures an image on the device’s camera if someone types in the wrong password and send you the image via email.

The Anti-Theft feature will prevent the loss of data and secure your photos and files when you turn on this tool. You can locate your device on a map, trigger an alarm, or lock your device with a custom message.

VPN service is included, but you need to download it separately on Google Play.

Signal Flare saves the current location of your phone to my.psafe.com when the battery reaches 5 percent.

Switches-Off Alert sends you an email with the last known location if your phone is turned off.

Advanced Protection Notice sends you an email if the advanced protection is turned off.

The App Lock locks your apps until you enter your secret pattern to unlock them.

The Call Blocker is another great security tool. It has the option to block a number that is selected from your contacts or recent calls.

The Memory Booster frees up the system memory whenever your device needs a boost. Two other features that are related to the memory booster function are the CPU Cooler Tool and the Game Booster.

Ease of Use

As we mentioned, DFNDR currently has over 200 million downloads. Part of the reason is it’s so easy to use. It’s easy to download and begin using right away. To download, you will just visit the Play Store and search for DFNDR and click download. The download only takes a few minutes to complete.

The dashboard is sleek and organized. You can easily navigate the security tools without any trouble.

Customer Service

While DFNDR has a large knowledge database on its website with lots of information, including Frequently Asked Questions, we were a little disappointed that there was no live chat available. Customers can submit tickets for support, but they may not get a reply for 24 hours.

Still, for a free antivirus, we can’t complain too much.

Free and Premium Version

As we said, DFNDR Security is completely free to use. This is great considering all the features that this security software offers.

However, with the free version comes many ads that can be distracting and annoying. If you don’t mind them, then you will never pay a penny. There is a Premium Version that is only $4.99 a year, and the only difference between it and the free version is that with the Premium Version, you won’t have any ads.

Pros and Cons

Every product has pros and cons, so don’t let any cons scare you off until you evaluate them. Here’s what we like and don’t like about DFNDR:

We like:

  • Great antivirus protection
  • Minimal system impact
  • Free version is excellent
  • The premium version is cheap and eliminates ads
  • Ensures optimal performance

We don’t like:

  • Ads in the free version
  • No live chat for customer support


To wrap up, DFNDR is a free security app for Android users with lots of great features. It will not only protect your device, it will add extra tools speed up its performance and keep it as secure as possible.

If you’re an Android user, you will want to give DFNDR a try, and since it’s free, you have nothing to lose.
