SMEs Face Rising Cyber Risks from Neglected Wireless Devices

Small and medium-sized enterprises (SMEs) are increasingly vulnerable to cyber threats due to overlooked wireless devices, including printers, routers, and scanners. A recent report by the International Data Corporation (IDC) revealed that nearly 37% of SMEs experienced security incidents linked to neglected connected devices in 2024. This alarming statistic highlights the urgent need for SMEs to rethink their cybersecurity strategies.

Understanding the Risks of Wireless Devices

Many SMEs assume that office devices like printers and scanners are harmless. In reality, these devices can be significant security risks. Often, they are not continuously monitored for unusual activity and frequently operate with outdated firmware. A compromised printer can become a “silent observer,” which may log, copy, or even forward sensitive documents without detection. According to HP’s 2025 Print Security Report, 52% of printers in SMEs had never received a firmware update, exposing them to known vulnerabilities.

The growing trend of remote work and the bring-your-own-device (BYOD) culture have led to an increase in wireless peripherals, such as Bluetooth keyboards and mobile printers. These devices often come with default settings that remain unchanged, leaving them susceptible to exploitation. Weak encryption can expose data during transmission, while unsegmented networks provide attackers the opportunity to jump from one device to another.

Essential Steps for Strengthening Cybersecurity

To combat these risks, SMEs can implement several straightforward operational changes:

1. **Update Firmware Regularly**: Manufacturers frequently release updates to address bugs and patch vulnerabilities. SMEs should ensure that all connected devices receive regular updates, ideally automated.

2. **Disable Unused Features**: Many wireless printers and scanners come with features that are often left active, such as remote access or FTP sharing. Disabling these features can reduce potential entry points for attackers.

3. **Change Default Credentials**: Default usernames, such as “admin,” and passwords like “1234” should be replaced immediately to enhance security.

4. **Create a Device Inventory**: SMEs should maintain a comprehensive list of all devices connected to their networks, from Wi-Fi cameras to wireless barcode scanners. Each device represents a potential entry point for cyber threats.

5. **Segment Your Network**: Keeping Internet of Things (IoT) devices and printing devices on a separate VLAN can help limit access to critical systems, even if one device is compromised.

Employee awareness is also crucial. Training staff to recognize the cybersecurity risks associated with wireless devices can significantly reduce vulnerability. It only takes one overlooked device to create a serious security threat.

As the adoption of smart devices and remote access tools continues to rise, SMEs must prioritize wireless devices in their cybersecurity strategies. By adapting their practices to address these “silent risk carriers,” businesses can protect their networks more effectively.

In conclusion, the evolving landscape of cybersecurity necessitates that SMEs take proactive measures to secure all devices within their networks. By following best practices and maintaining a vigilant approach, small businesses can enhance their security posture and reassure clients about their commitment to data protection. Ultimately, convenience should never come at the cost of privacy.
