Introduction
Work devices like laptops, tablets and mobile phones are essential tools for getting things done. They give us access to company systems, emails and sensitive information. However, these same devices can also be a major security risk if they are lost, stolen or compromised. Cyber criminals often target devices because they are easier to access than secure company networks. This blog explains why device security matters and how you can reduce risks with simple habits.
What is device security
Device security refers to the steps taken to protect computers and mobile devices from theft, misuse and cyber attacks. It involves both physical security, which prevents devices from being lost or stolen, and digital security, which protects them from hacking or malware. Even organisations with advanced cyber security systems can be exposed if just one unsecured device becomes a weak entry point.
Why device security matters
Your work device is more than just a tool. It holds personal and professional data, emails, saved login details and access to company accounts. If someone else gains access, they could misuse your identity, read sensitive messages or steal confidential information.
A compromised device can also be used to spread malware or gain deeper access into company systems. The impact can range from minor inconvenience to serious financial loss or data breaches that harm the entire organisation.
Common risks to device security
Security risks often come from everyday actions. Leaving your laptop unattended, especially in public areas like airports or coffee shops, gives thieves an easy opportunity. Using weak screen passwords or not locking your device when stepping away increases the chance of unauthorised access.
Connecting to public Wi-Fi without protection exposes your data to interception. Installing unofficial software, delaying updates or letting others use your work device can unintentionally introduce risks. These behaviours seem harmless at first but can quickly lead to security problems.
Physical security best practices
Physical protection of devices is often overlooked, yet it is one of the simplest ways to prevent data breaches. Keep your device within sight when working in public places and never leave it in a car or shared space where it can be stolen. When working in open environments, use a laptop lock to secure it to your workspace.
If your device supports tracking features such as Find My Device, make sure they are enabled so it can be located if lost. Always report missing devices immediately so IT can disable access before any damage is done.
Digital security best practices
Keeping devices safe also requires strong digital protection. Start by locking your screen whenever you step away, even for a short moment. Use strong passwords or passphrases and enable biometric security if available. Regularly updating your operating system and applications is essential because updates often fix security vulnerabilities.
Avoid installing unknown software or browser extensions, as these may contain malware. When working remotely, only connect to trusted networks and use a VPN if required by your organisation. Device encryption should always be enabled to protect stored information in case the device is lost.
Securing mobile devices
Mobile phones are often just as risky as laptops but receive less attention. Many people store company emails, contacts and files on their phones, making them valuable targets for attackers. Protect your phone with a PIN, password or biometric lock, and avoid downloading apps from unofficial app stores. Be cautious when scanning QR codes or clicking links sent through messaging apps, as these can lead to malicious sites.
If your company uses mobile device management tools, make sure your device remains connected so it receives security updates and policies. Enable remote wipe functionality so your data can be erased if the device is ever lost or stolen.
Remote and hybrid work risks
Working away from the office has become normal for many people, but it introduces extra risks. Home Wi-Fi networks are often less secure, especially if default passwords have never been changed. Family members may accidentally access work information if personal and professional devices are mixed.
Public Wi-Fi, while convenient, can expose sensitive data to attackers who monitor unsecured networks. To stay safe, secure your home Wi-Fi with a strong password, use company-approved storage locations for files and avoid discussing confidential information in public spaces.Simple checklist for employees
What to do if your device is compromised
If you suspect your device has been tampered with or infected, act quickly. Stop using it for work tasks and disconnect from the internet if instructed by IT. Report your concerns immediately, even if you are not completely sure something is wrong. Your security team can investigate and take action to prevent further risk.
Do not try to solve the issue on your own by installing random tools or deleting files, as this may make the situation worse. Follow official guidance until the device is considered safe again.
Simple checklist for employees
Lock your screen every time you step away
Keep software and apps updated
Use strong passwords and MFA
Avoid public Wi-Fi without protection
Report lost, stolen or suspicious devices immediately
Do not install unapproved software
Keep work data on company systems only
Conclusion
Device security might seem simple, but it forms a critical part of protecting company data. Cyber criminals often look for the easiest way in, and an unattended or unsecured device is exactly that. By taking responsibility for both the physical and digital safety of your work devices, you help protect yourself, your team and your organisation. Small actions, done consistently, make a big difference in staying secure.
