Mobile security: Your first line of defence in 2026


Picture a modern-day workplace - colleagues working together from bustling cafés, airport lounges, and home studies, all seamlessly connected by the powerful mobile devices they carry.

Smartphones and tablets have become essential to business life, driving unprecedented flexibility and productivity - achievements that would have seemed fanciful just ten years ago.

Yet, as organisations have capitalised on this newfound agility, a darker reality has emerged. The threat landscape surrounding mobile technology has expanded swiftly, catching many businesses off guard with its pace and complexity.

ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ

The wake-up call

The shift began subtly, with staff gradually turning to their personal devices for work tasks - accessing confidential customer information, financial data, and intellectual property from wherever they happened to be. While this flexibility brought undeniable benefits, it also introduces significant security concerns.

The European Union Agency for Cybersecurity (ENISA) Threat Landscape 2025 (ETL 2025) report serves as a definitive barometer for the cybersecurity climate of the European Union.

The report confirms a historic shift in EU cybersecurity - mobile threats now represent the single largest risk category, accounting for 42.4% of all incidents1.

The rise of generative AI is empowering cybercriminals with sophisticated tools that significantly threaten mobile security. Deepfake videos and highly convincing, personalised messages, which can flawlessly mimic colleagues or senior leaders, are now being delivered directly to mobile devices, making phishing attacks more effective than ever. With employees increasingly relying on their phones for communication, the line between authentic and fraudulent messages becomes even harder to distinguish on mobile platforms. Furthermore, the rapid pace of these AI-driven attacks often outpaces conventional mobile security measures, leaving organisations vulnerable to breaches initiated through smartphones and tablets.

ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ

The human factor

As remote work and Bring Your Own Device (BYOD) policies become the norm, the challenge grows. Most organisations allow employees to use personal devices for business, but less than half had adequate security in place. Many employees, unaware of the risks, don’t change their passwords after breaches or fail to update their devices, which can leave gaping holes in the company’s defences2.

ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ

The cost of complacency

For some businesses, it can take a security breach to bring the risks sharply into focus. The financial repercussions can be immediate and significant - the most serious incidents typically exceeded £8,000 in costs, while the average global data breach soared to £3.3million3. However, the most damaging consequence is often the erosion of trust. Customers, previously loyal, choose to take their business elsewhere after finding out their information had been compromised. Regulators are equally unyielding: penalties for failing to comply with GDPR and equivalent regulations could run into the millions, posing an existential threat to smaller enterprises.

ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ

Turning the tide

However, the outlook is far from bleak. Progressive organisations are reshaping the story. No longer viewing mobile security as a mere compliance tick-box or an afterthought, they are elevating it to a strategic priority - an essential pillar of organisational resilience.

They are achieving this by implementing sophisticated Mobile Threat Defence (MTD) platforms that enhance traditional antivirus, harnessing AI to detect and neutralise threats before they can do damage. Multi-factor authentication is being rigorously enforced, devices and applications are kept consistently updated, and - crucially - a security-conscious culture is being nurtured so that every employee recognises and embraces their responsibility in safeguarding the business.

Organisations are also implementing device management solutions to ensure they have full visibility and control over their mobile devices. This includes apps that provide real‑time monitoring of mobile device security, identifying phishing and malware threats so issues can be addressed quickly. Crucially, this protection must also extend to employee‑owned devices while maintaining privacy and flexibility.

The new advantage

Organisations that excel in mobile security aren’t simply sidestepping catastrophe - they’re securing a real advantage over their competitors. Their commitment to safeguarding data earns greater customer trust and positions them as exemplary custodians in the eyes of regulators. What’s more, their workforce enjoys the confidence to collaborate from any location, assured that robust security measures underpin every aspect of their working day.
