Mobile viruses and threats are on the rise, says security experts AVG. It’s easier than ever to run your entire business from your phone or tablet, but if your security is weak hackers could get access to business-critical apps, software and data.
Security and anti-virus protection is vital for your computers, servers and systems, but most of us don’t consider anti-virus protection for our phones. Are you sure your mobile phones and tablets secure?
Should I have anti-virus protection on my phone or tablet?
Unlike your business computer, it's not a given that you need security software on your mobile device or smartphone. While your smartphone offers protection against some mobile threats, it's useless against others. This article will help you understand the issues, but it may be wise to consult a knowledgeable IT supplier if you need further help.
Mobile security is a complex issue. Malware and viruses - which security software can protect against - are not the most serious threats you face. Although growing, the chances of infection remain low. You're far more likely to suffer data loss by having a mobile device lost or stolen.
Your first priority should therefore be to take some basic mobile security steps.
- Make sure all your mobile devices require a passcode, FaceID or fingerprint to be entered before people can access data or functions.
- Set up two-factor authentication on your user ID, which adds an additional layer of security when using any device to which it is linked. This feature is available for both Apple and Google.
- Implement free services like Find My iPhone (for Apple devices) or Android Find My Device (for Android devices)to keep track of all business devices.
- Set up remote wipe, so you can erase the data on a device if it's lost or stolen. Find My iPhone and Android Find My Device offer this option.
- Back up the data on your mobile devices. The data on them - including your contacts and files - may be more valuable than the device itself. Some programmes like Dropbox will automatically sync for you.
Once you've taken these steps, you can consider whether mobile security and anti-virus software has a role to play in keeping your devices, and the data on them, safe.
Do you need mobile security software for your phone?
The Android operating system is more vulnerable to malware than Apple mobiles and tablets, says security software firm NordVPN. But that doesn’t mean Apple phones are immune.
Here are some things to think about if you’re considering mobile security software.
- Devices running Apple's iOS (like iPhones and iPads) are less susceptible to malware, because they take a ‘walled garden' approach to apps. You can only install apps from official app stores, and each is checked for malware. These operating systems are also tightly controlled. When a security problem is identified, it's usually fixed quickly.
- Devices that use Google's Android operating system (there's a huge range) are more susceptible, because Google allows developers to freely create and offer apps outside of the official app store. Potential hackers can even access and modify the Android software itself. Although Google does fix Android vulnerabilities promptly, many devices have custom versions of Android that may make devices more vulnerable.
So, you need mobile security software for your phone?
The case for security software is certainly stronger for Android devices, as they have fewer built-in checks to block malicious apps and downloads. However, Apple devices can still be targeted, with vulnerabilities emerging all the time, particularly for those operating older devices and operating systems.
Are your mobile devices secure?
When deciding whether you need security software for your mobiles, think about how much control employees have over their mobile devices, and how much control they should have.
Mobile device management (MDM) software allows you to manage the devices in your business via a central control panel. For instance, you can restrict staff from installing their own apps or limit how files are shared.
If your company owns the mobile devices that staff use - and they are used only for business - MDM software is a powerful way to lock down those devices. If your mobile devices are locked down they’re more secure and less of a risk.
However, if your company allows staff to use their own devices, known as bring your own device (BYOD), it's harder to restrict what they can and can't do. If you enable staff to access your network with their own devices, then mobile security software is a sound investment. You’ll need a process in place to ensure they install the software and keep it updated.
How to protect your mobile devices from rogue apps and other threats
Security software can be effective in protecting you and your staff’s mobile devices against rogue apps. These mobile apps aren't strictly malware or viruses, but trick users into sharing important data.
These threats are real and growing. In early 2025, Apple and Android users were targeted by SparkCat, a rogue piece of software that attempts to steal cryptocurrencies. This isn’t the first, either.
Malicious apps work by tricking users into granting permissions to information without fully understanding the implications.
The app could then harvest and use this data. Names, addresses, phone numbers and email addresses are valuable to online criminals because they can use them to create convincing fake emails or simply sell them to other scammers.
Many mobile security packages include protection against threats like these, as well as blocking fake phishing emails and websites. These are increasingly aimed at mobile users because when they're on the go, people often respond without stopping to think.
Mobile security software is relatively cheap and acts as an additional line of protection.
How do you know your mobile device is secure?
As you've seen, mobile device security can seem complicated. What's more, it's an area that's changing fast. How we use mobile devices in business is constantly evolving - and the best way to protect them is evolving too.
However, a good place to start is by asking yourself these three questions:
- Do your mobile devices run Android or Apple? The open nature of the Android operating system makes it more vulnerable to threats. If you’re running Android, it’s wise to consider mobile security software. Apple software has historically been more secure, but there are no guarantees hackers won’t find a vulnerability, so don’t be complacent.
- How much control do you have? If staff only use mobiles for work, you can – and should – lock them down. If you enable staff to use their own devices, the more vulnerable you and your systems are.
- What data is accessible on your devices? If you're working with sensitive information like customer data and payment details, then security software adds an additional layer of protection. Remember, you also have legal obligations when it comes to data protection under GDPR.
Finally, remember that your people have a big role to play in ensuring mobile device safety. The more they understand the dangers and risks posed by mobile devices, the lower the chance of running into problems.
Update your data protection and IT policies to cover mobile devices - and check your staff know who to speak to if they need help.
