Experts: Use VPN on public WiFi, adds data protection

KUCHING (Aug 25): Using a Virtual Private Network (VPN) enhances security on public WiFi by adding an extra layer of encryption to protect data from unauthorised access.

Yap Chee Yuen, founder and technical director of Infosyte Sdn Bhd and a certified trainer with over 20 years of experience in information and communication technology (ICT), said that using a personal hotspot through one’s smartphone is generally safer than connecting to public Wi-Fi.

However, if public Wi-Fi must be used, he advised activating a VPN for added security.

“Hotspots are typically safer as they come from your own device. Public Wi-Fi, especially when not encrypted, poses significant risks. Hackers can set up rogue access points, tricking you into connecting and then redirecting you to malicious websites.

“If a hotspot isn’t available, using a VPN is essential for protecting your data,” he explained.

Yap shared this advice during the Tek Talk programme entitled ‘Getting Ready for E-invoice: Comprehensive Cybersecurity Strategies for Businesses’ on Thursday night, in response to a question from host Pattrik Ting.

Ting, who is also general manager of sales at K Media Marketing, had inquired about the safety of using a hotspot, particularly in areas with weak internet connections.

Kelvin Lim, vice president of Infra365 and an expert in cybersecurity and cloud services, concurred with Yap.

Lim agreed that while using a hotspot is preferable, VPNs provide a significant boost in security when accessing less secure networks.

“Having a VPN is crucial. While a hotspot is definitely safer than public WiFi, I always make sure my VPN is on before connecting to any public network.

“It adds an essential layer of protection, as we can’t always predict what might happen on these networks,” he said.

Yap also discussed VPN options, advising users to either subscribe to commercial VPN services or set up their own VPN at home if they have the technical expertise.

“There are many VPN services available online. Do your research and choose one that fits your needs.

“Anything encrypted is better than unencrypted, and relying on public WiFi without protection is risky,” he added.
