The inconvenient truth about personal devices at work

The workplace of 2025 is more flexible, more connected, and more personalized than ever before. Bring Your Own Device (BYOD) has become the norm.

With the global market for BYOD and Enterprise Mobility valued at $129,2 billion in 2024 and projected to reach $331,6 billion by 2030, it is clear that this is an ever-evolving trend and not a passing phenomenon.

“However, behind this growth lies an inconvenient truth: personal devices are one of the weakest links in the cybersecurity chain, especially when properly managed,” explains global security software company ESET.

One of the key security concerns around BYOD is the lack of uniform and standardized protection across all personal devices. Unlike corporate devices, personal devices often lack critical security safeguards such as endpoint protection, encrypted storage, or even strong passwords.
The absence of this protection widens the attack surface for a business, which cybersecurity managers are called upon to manage.

Personal devices, such as phones and laptops that employees bring from home, may seem practical, but they often become a "backdoor" for cyberattacks, warns ESET. This is because they are not always adequately protected: they may not have antivirus, strong passwords or encryption.

If the user accidentally clicks on a suspicious link or downloads a malicious application, attackers can gain access to corporate data.

Furthermore, when the same device is used by other family members or connected to open Wi-Fi in cafes and airports, the risk increases. So, without the right training and necessary security controls, personal devices can become the weak link in a company's protection.
