Mobile security for business in 2025: 

Smartphones and tablets are as essential to business operations today as laptops. Yet, 80% of businesses still lack strong mobile security measures. With cyber-attacks happening every 19 seconds, the need to protect your business has never been more important.

Since the launch of Gmail in 2004 to Protected Computing in 2022, Google has led the way in cybersecurity innovation, continuously finding new ways to secure data.

Google’s innovative security features, along with solutions like Three Mobile Protect*, help businesses stay ahead of new threats, ensuring a safer future for everyone. This guide covers essential mobile security strategies and tools to help secure your business’ data and reputation.

Mobile security is a critical yet often underestimated aspect of business security processes. A mobile user is 18x more likely to be exposed to a phishing attempt than a laptop user. Smartphones and tablets are no longer simple communication devices but are now mini-computers containing sensitive information. Without the right protection, your business’ data could be at risk.

Hybrid work has amplified these risks, with home offices often lacking the strong network security measures of traditional workplaces. Half of businesses (50%) report having experienced some form of cyber-attack in the last 12 months. But with various threats coming from multiple directions, where should you start with finding the right protection?

Data breaches cost UK businesses over £20k per year. Small security breaches may not seem like a big threat on their own, but they do add up.

Together, security breaches and threats potentially cost your business thousands in downtime. They also harm your reputation and can lead to regulatory fines. With increasing expectations for robust data protection, demonstrating strong security practices is now a necessity.

Cyber threats are also evolving. As technology advances, the techniques of cybercriminals have become more sophisticated. Phishing attacks used by artificial intelligence (AI) and weaknesses from the Internet of Things (IoT) are increasing. AI can now craft highly personalised messages, tricking employees into revealing sensitive data. Similarly, vulnerabilities in automation software can serve as entry points for attackers. This makes the threat landscape more complex and puts businesses at greater risk.

Since 95% of data breaches happen because of human error, it is important to prioritise cybersecurity training. We need to learn how to spot and prevent attacks. But securing mobile devices requires a multi-layered approach, combining advanced security technologies with team training.

Now is the time for businesses to review their current security measures. With global cybercrime costs projected to reach up to £8.4 trillion globally by 2025, proactive investment in cybersecurity is essential to counter AI-driven attacks and IoT vulnerabilities.

Let’s take a closer look at the steps you can take to secure business mobile devices effectively in 2025.

With multiple devices connected on a network, end-to-end protection is paramount. Mobile security solutions like Three Mobile Protect (powered by Corrata)* offer comprehensive cybersecurity protection against phishing, malware, and advanced cyber threats.

Encryption protects sensitive information by making data unreadable to unauthorised users. Mobile Device Management tools allow businesses to manage and secure devices remotely, maintaining control without compromising privacy.

Even the smallest human error can lead to a breach, so it’s important to maintain regular training for your team. This includes training on phishing protection, safe browsing, and data handling.

A VPN (virtual private network) is essential for hybrid workers, keeping data secure so employees can access resources from anywhere. Look for devices that offer a built-in VPN for secure communication over public networks.

AI is revolutionising how cybersecurity AI algorithms can quickly analyse large amounts of data. From encryption to endpoint protection, software is designed with baselines of typical behaviour integrated, meaning it can identify any unusual patterns before they grow.

AI enables businesses to respond in real time. For example, AI-powered systems can detect phishing attempts, malware, and unauthorised access attempts, significantly reducing response times compared to manual monitoring.

While 36% of UK businesses already use AI for cybersecurity, many still lack comprehensive mobile protection. By using AI with specific mobile security solutions, businesses can improve their ability to stop and respond to advanced security risks as they develop.

However, despite AI's advantages, training and manual processes remain essential, as 87% of UK organisations are said to be at risk of cyberattacks in the age of AI. Human oversight helps fill gaps left by automated systems. Ensuring that your team are well-trained in identifying threats and understanding security practices provides an additional, necessary layer of protection.

Google’s commitment to cybersecurity is rooted in a history of pioneering advancements, and continuously innovating its products and partnerships. As noted in the latest Android Security Paper, Google’s latest devices use industry-leading security features to protect user data –playing a major role in combatting cyber threats.

Devices in the Google Pixel 9 range have built-in security features to safeguard your data. This includes:

• Multi-layered security with the Titan M2™ chip and Tensor security core**
• Automatic updates to stay ahead of evolving threats
• Built-in VPN by Google One for secure browsing on public networks***

With Three Mobile Protect, businesses gain access to an intuitive app and portal that provide easy-to-use visibility into the status of devices, threats, and web traffic. This holistic approach helps businesses proactively manage their mobile security, ensuring resilience against evolving cyber threats.
