Smartphones and tablets have become essential to modern work, whether checking emails, accessing shared drives, or joining video calls. But as mobile use increases, so does the risk of cyberattack.
Many UK businesses still treat mobile devices as an afterthought when it comes to cyber security – and that’s a dangerous blind spot.
The Changing Mobile Threat Landscape
Historically, IT security focused on office-based networks, servers, and laptops. But the workplace has shifted. Today’s teams are just as likely to be working from cafés, co-working spaces, or their homes, on personal mobile devices.
That flexibility has its benefits, but it also introduces new vulnerabilities:
- Mobile devices often sit outside traditional endpoint protection
- Devices are more likely to be lost or stolen
- Staff connect to unsecured Wi-Fi networks
- Attackers are targeting mobile users directly, with phishing and malware campaigns tailored to smartphones
Relying on built-in protections from iOS or Android isn’t enough. Modern smartphones have native security features, but they’re not impenetrable – and attackers know it.
Common Mobile Security Gaps in UK Businesses
At Dr Logic, we support London-based businesses across the creative, financial, and professional sectors. In the past year, we’ve helped clients deal with a growing number of mobile-related security issues, often caused by:
- Lack of visibility: Businesses often don’t know how many mobile devices are accessing company systems, let alone what software they’re running or whether they’re encrypted.
- Unsecured personal devices: Employees use their own smartphones for work, but without any security policies in place. This “BYOD” (bring your own device) approach can quickly spiral into a compliance headache.
- Outdated software: Many mobile operating systems and apps are not updated regularly, leaving known vulnerabilities unpatched.
- Phishing and smishing: Attackers are increasingly targeting mobile users with deceptive text messages, emails, and fake login screens. A single tap can compromise accounts or install malware.
- Public Wi-Fi threats: Staff working on the move may connect to unsecured Wi-Fi networks, opening the door to man-in-the-middle attacks and data interception.
If you’re relying on cloud platforms like Google Workspace or Microsoft 365, mobile devices are more than just phones – they’re potential entry points into your entire digital infrastructure.
What Happens If You Ignore Mobile Security?
A single compromised device could expose:
- Client data
- Internal documentation
- Financial records
- Credentials that unlock wider systems
For regulated industries, that could mean fines or legal fallout. For any business, it’s a reputational risk.
And the threat doesn’t stop at the device. If a criminal gets in via a phone, they can move laterally into:
- Shared drives
- Cloud apps
- Communication tools
- Financial platforms
How Smart Businesses Are Securing Mobile Devices
The good news? Securing mobile endpoints doesn’t have to be complex. With the right strategy and tools, you can dramatically reduce the risk.
Here’s what we recommend:
Use Mobile Device Management (MDM)
Deploying an MDM platform gives you control. You can:
- Enforce encryption
- Wipe lost or stolen devices remotely
- Manage app access
- Apply security policies consistently

Create a Clear Mobile Device Policy
Define what’s allowed, what isn’t, and what’s expected from staff. This is especially important in BYOD environments.
Keep Devices Updates
Set up automatic updates where possible. A missed patch can be all it takes for an attacker to get in.
Train Your Team
Many mobile attacks rely on human error. Help your team spot phishing links, avoid sketchy apps, and connect safely on the move.
Enable Multi-Factor Authentication (MFA)
Require MFA for mobile access to cloud apps and internal systems. It’s a simple, effective way to block unauthorised logins.
Why Mobile Security Needs to be a Priority Now
Mobile working is the new normal, and that means mobile security can’t be ignored.
Whether your business is scaling, operating in a regulated sector, or just wants to protect client trust, now is the time to act.
