What Are Mobile Security Apps?

Mobile security apps cover all your data and privacy security needs. These apps are in charge of protecting both personal and business information stored on and transmitted from smartphones, tablets, laptops and other mobile devices.

One feature of these apps is user authentication. Mobile devices with installed mobile security apps can authenticate users and protect or restrict access to data stored on the device through the use of passwords, personal identification numbers (PINs), pattern screen locks or more advanced forms of authentication such as fingerprint readers, eye scanners, and other forms of biometric readers.

Why Do You Need A Mobile Security App?

Mobile security apps serve as a protection against cybersecurity threats that target mobile devices. With the continuing growth of mobile devices, cybercriminals see a great opportunity in exploiting vulnerabilities in mobile operating systems (OS). Many of today’s mobile devices like smartphones and tablets run on Android, with iOS occupying a smaller yet more loyal market share.

Using similar tactics that they do on desktop computers like those running on Windows, cybercriminals employ malware like viruses and spyware for Android and iOS devices. They also saw unprotected wireless public networks as a new playground for them to spread malware and stage cyber attacks. Cybercriminals can fool unaware users to input their personal data on a phishing portal or make them download mobile Trojans that appear as legitimate apps on app marketplaces like Google Play.

Like their desktop counterparts, mobile security apps have features that shield mobile devices users against these attacks. Personal firewall filters traffic and blocks bad ones. Antivirus or anti-malware stops malware and removes them from the system. Encryption and VPN help in keeping your personal data protected from the prying eyes of hackers. Other features include password management, anti-phishing, spam blocking, and Wi-Fi scanning.

Top Risks & Threats Targeting Mobile Devices

Mobile security threats and other forms of Internet risks continue to evolve through the years. From traditional malware forms like viruses, spyware, and Trojan horses, these threats combine the features of different malware and other cyber attacks. These developments show that cybercriminals have stepped up their game, so users of smartphones, tablets, and mobile devices should level up theirs, too. Here are some of the top risks and threats observed by experts in recent years.


Stalkerware comes in the form of either trackers or full-fledged tracking apps designed to locate victims’ coordinates and get into text messages. They were once legitimate apps found on Google Play. Eventually, the marketplace changed its policy, removing these apps from the system.

However, developers of these apps and third-party sites still offer them as downloads. Once installed, a stalkware app can make the location of a person accessible to third parties. While simplified as commercial programs, stalkerware can allow third-parties to extract almost any date on compromised devices. These include photos, voice calls, text messages, and key logs.


Advertising apps or adware increased last year with the key purpose of harvesting data on mobile devices. Detected adware installation packages almost doubled from 2018 to 2019. Fortunately, while these packages auto-generate, most of them fail to reach their target users. Mobile security apps immediately catch and prevent them from propagating. Cautious users also instantly find and uninstall them if given an option.

Last year, adware developers not only produced tens of thousands of packages but also upgraded them, enabling them to bypass OS restrictions. For example, KeepMusic adware family can loop a mute MP3 file, fooling the OS that a music player runs. A background process also runs at the same time, which can request a display time from the server.

Phishing Malware

Mobile financial malware like Trojan-Banker.AndroidOS.Gustuff.a can be used to steal money from bank accounts. It infects the device and sends a text message requesting for fund transfer to a special bank phone number. The bank then transfers the funds from the device owner’s account to the person behind the malware.

Another strategy steals online banking credentials, wherein cybercriminals put a phishing window on the victim’s device. The window appears similar to the bank’s login portal, luring the victim to input credentials. Once done, the cybercriminal can perform unauthorized bank transactions. Today, banks have anti-fraud systems that prevent these transactions from happening.

Mobile Trojans

Mobile Trojans have become more common in Android’s app marketplace, Google Play, in the same way how stalkerware became prevalent before 2018. Appearing as legitimate apps, mobile Trojans can allow cybercriminals to bypass SafetyNet, Android’s built-in antivirus protection.

Without SafetyNet, an Android device can only be protected with the help of a third-party mobile security app. Unaware users potentially download mobile Trojans as they pretend to be popular mobile apps like photo editors, wallpaper tools, mobile banking apps, or mobile security apps for mobile games. Some even gain credibility with hundreds of thousands of downloads on the Google Play marketplace.

Things To Consider When Choosing Mobile Security Apps

If you are planning to buy a mobile security app for your mobile devices, here are some of the features and guidelines you should look at.

Operating System Update With Security Patches

A good mobile security app always reminds you to update your phone’s operating system. Mobile operating systems like Apple iOS and Google Android provide regular updates to users that resolve security vulnerabilities and other mobile security threats.

Updates and patches also provide additional security, performance optimizations, and features to users. These upgrades aren’t always updated automatically, so mobile device users may need to turn on automatic updates or update their phones and apps manually on a regular basis. 

User Authentication Feature

Restricting access to the device by requiring a user authentication system includes a screen lock or password for personal identification number (PIN), but these measures are typically turned off by default. Some mobile security apps have this feature, make sure to check the app before purchasing.

Spyware Detection

A mobile security app with spyware detection will protect your devices by blocking system infiltrators. Spyware detection is a vital feature needed by a mobile security app. Your data and privacy will be protected with a mobile security app with a spyware detection feature.

Storage Encryption

Most devices have encrypted phone storage as some of them have it as a hidden feature. It is tough for hackers to thieve your data. If the storage is not encrypted, it is vulnerable to hacks and your personal info is in constant danger of getting hacked including photos, emails, and even access to networking accounts.

Remote Wipe Setup

Nowadays mobile devices have the functionality to remotely wipe data when the smartphone is stolen. One can set up iCloud on your iPhone or the useful Google Sync feature to Android. If the device is lost, one can make use of a remote wipe to delete information from the device once it is connected to the web.

Performance Optimization

Mobile security apps with this feature help your device to work on its highest level. This feature helps free up storage space by cleaning out junk, speed up devices with RAM boost, and extend battery life by adjusting power consuming Android settings.


Lastly, you should consider the price when purchasing a mobile security app. Some applications offer a lot of features with a good price. Always remember to check all the features of the mobile app before purchasing it.
