Armour Cybersecurity Small & Medium Cybersecurity Enterprises Series
Cybercriminals are like water. They follow the path of the least resistance. They look for an easy way into your organization, and once it is found, they strike. When the attack economics are in their favour, they scale up the operation. They rinse and repeat. But when the cycle ends, the search for a new soft underbelly resumes. They then look for new techniques, vulnerabilities, and business modalities they can exploit.
For the past decade, businesses have ramped up their investment in traditional cybersecurity solutions. The solutions have been focused on and designed to protect devices, networks, and employees in the office. The office was declared a “secured perimeter,” and any device connected to the network had to be verified and approved. External traffic to and from these devices was also monitored. All to ensure that an office is a safe place If you have not assessed your current defences recently, a cybersecurity assessment is the first step toward understanding where the gaps are.
But over the last few years, especially after the COVID-19 pandemic, we have seen a monumental shift in how and where we do our work. Employees today work from anywhere. They are using any device, connecting to any network, and adopting any application that makes their tasks more manageable. And in this context, we have realized how critical mobile phones have become for workforce productivity.
Today mobile devices mirror your corporate data onto a smaller form factor and hold the keys to your corporate kingdom. From replacing passwords with 2-Factor Authenticating Apps to enabling Office365 access and more. These devices have become both keepers of sensitive data and enablers of identity and access to additional data not stored on the device. They are now, de facto, a part of your core technology ecosystem. And as such, it must be protected.
Why do you need a mobile security solution?
According to the Verizon 2025 Mobile Security Index, 85% of security professionals say mobile device threats have increased over the past year, and 80% of respondents consider mobile devices critical to their operations.
In plain language, your business data is viewed, accessed, downloaded, and shared on mostly unprotected and unsecured devices.
These devices can be infected with malware, phishing for credentials, leaking information externally, spoofing authentications, and spying on. In some cases, unsecured devices even led to ransomware attacks. Without a proper solution, an attacker can lurk without interruptions or the possibility of being discovered.
The numbers back this up: Kaspersky recorded 33.8 million mobile attacks in 2023, a 52% jump from the previous year. Banking trojans on Android devices surged 56% in 2025, and 70% of workers still use unsecured personal devices to access corporate data.
Today unprotected mobile phones are fertile ground for attackers. It is their latest path of least resistance Organizations without a tested cyber incident response plan take far longer to contain the damage once an attacker gets in through a compromised device.
Another problem is that Small and Medium Businesses rely on their IT provider, internal or external, or Managed Security Services providers to protect their business. However, most IT providers are spread thin on maintaining IT systems properly and usually do not have the focus nor expertise to secure mobile devices properly. As a result, most businesses have a blind spot that exposes their mobile devices to cybercriminals.
What does a good mobile security solution look like?
Before we explain what a good security solution looks like, it is worth noting that the passcode or password you have on your phone is not considered a mobile security solution. The same goes for a Mobile Device Management (MDM) solution. MDM has some features that sound like they are security-related; they are not. MDM deals primarily with policies and compliance but does not have preventative and detection technologies to stop cybersecurity attacks A proper endpoint protection strategy covers what MDM cannot.
You should look for a solution that provides 360 degrees of protection against all attack vectors. Insist on a solution that protects the device hardware, the Operating System, the applications, and the network/connectivity layer.
- The solution needs to defend against all types of modern attacks. Prevent malware from infiltrating the device by detecting and blocking the download of malicious codes. Ensure the device is not exposed to compromise with real-time risk assessments detecting attacks, vulnerabilities, configuration changes, and advanced rooting and jailbreaking.
- Risk visibility is also crucial. Without a complete view of your organization’s mobile security posture, you will not be able to mitigate risk and accelerate remediation effectively Running a regular vulnerability assessment across all endpoints, including mobile, makes this possible.
- Do not let the solution restrict your technology. Scalable and fast deployment that supports every device type, operating system, and device ownership model (company or BYOD) is a must.
- Security solutions can become an annoyance when they get in the way. Good solutions have minimal impact on the device’s usability, user experience, data consumption, and battery levels.
- Mobile devices are hybrids. They store both corporate and personal information. Make sure the solution you choose ensures that data is kept private from everyone, especially when the device belongs to an employee. If the solution you intend to implement doesn’t follow the privacy-by-design principles, it is not the right one for you. Privacy is paramount when it comes to personal mobile devices.
Last but not least point, it is not all about technology. You should choose the best technology on the market; however, the technology without experts that can set it up, configure and manage it properly and consistently with the right dedication and focus is as good as a brick Pairing the right tooling with structured security awareness training ensures your team knows how to use their devices safely.
Before you decide on a solution, consult with cybersecurity experts who can recommend the right approach for your specific business needs. It is quite affordable nowadays, and organizations can also benefit from vCISO services to strengthen their mobile security strategy and improve ROI.
Mobile Device Security Q&A
Q: What is the biggest mobile security risk for small businesses?
A: The biggest risk is unmanaged BYOD devices accessing corporate email, cloud storage, and business applications without any security controls. These devices sit outside your IT team’s visibility, which means malware infections, phishing compromises, and data leaks can go undetected for weeks.
Q: Is MDM enough to protect mobile devices?
A: No. Mobile Device Management handles policies and compliance, such as enforcing screen locks or remotely wiping a lost phone, but it does not detect or block malware, phishing attacks, or network-level threats. You need a dedicated mobile threat defence solution alongside MDM.
Q: How do I know if my employees’ phones are compromised?
A: Without a mobile security solution, you likely would not know. Signs include unusual battery drain, unexpected data usage, apps the user did not install, or redirected web traffic. A proper mobile threat protection tool provides real-time alerts when a device is compromised.
Q: Should I ban personal devices or allow BYOD?
A: Banning personal devices entirely is usually impractical and can hurt productivity. A better approach is to implement a BYOD policy with mobile threat protection, containerization for corporate data, and clear acceptable-use guidelines. This balances security with employee flexibility.
Q: How often should mobile security policies be reviewed?
A: At minimum, review your mobile security policies annually and after any significant incident. The mobile threat landscape changes quickly, with new malware families and attack techniques emerging every quarter. Regular policy reviews, combined with ongoing employee training, keep your defences current.
