VPN for Remote Work: Protect Your Business Data Anywhere

The Real Security Risks of Remote Work

When you work from home or a coffee shop, your data travels over networks you do not control. A home router is often misconfigured or running outdated firmware. A cafe's Wi-Fi network may be shared with dozens of strangers, some of whom may be running passive sniffing tools. Corporate VPNs address the office-to-company connection, but they often leave employees' local network security unaddressed -- and increasingly, employees use personal devices that never connect to the corporate VPN at all.

What Data Is at Risk?

The most sensitive data transmitted during remote work includes login credentials for corporate systems, email and messaging content, file attachments containing confidential documents, video call metadata, and access to internal tools and APIs. Even if individual data is encrypted at the application layer, an attacker on the same network can use metadata -- timing, size, frequency of packets -- to reconstruct behavioral patterns or identify the tools you are using.

Threats at Public Wi-Fi Hotspots

• Man-in-the-middle attacks that intercept traffic between you and websites
• Evil twin hotspots -- fake Wi-Fi networks with convincing names
• ARP spoofing -- redirecting your traffic through an attacker's device
• Passive packet capture -- recording all traffic for later analysis
• DNS hijacking -- redirecting your DNS queries to malicious servers

How a VPN Secures Remote Work

A personal VPN like Nexun encrypts all outbound traffic from your device before it touches the local network. Even if an attacker on the same Wi-Fi captures your packets, they see only encrypted ciphertext -- unusable without the session keys. Your DNS queries are routed through the VPN tunnel, preventing DNS hijacking. Your real IP is hidden, making targeted attacks against your specific device harder to execute.

GDPR and Employee Data Protection

Under GDPR, organizations have an obligation to protect personal data with appropriate technical measures. For remote workers handling customer data, this includes securing the transmission channel. Using an unencrypted connection on public Wi-Fi to access systems containing personal data may constitute a data protection failure under Article 32 of GDPR. A VPN -- particularly one that leaves no server-side logs like Nexun -- is a straightforward technical control that supports compliance.

Personal VPN vs Corporate VPN

Many companies deploy corporate VPNs (like Cisco AnyConnect or Palo Alto GlobalProtect) that route all traffic through company infrastructure. These are designed for accessing internal resources -- not for personal privacy. A personal VPN like Nexun complements a corporate VPN: use it on networks where you do not control security, for non-corporate work, or when a corporate VPN is not available. They serve different purposes and can be used independently.

Securing Video Calls and Collaboration Tools

Tools like Zoom, Microsoft Teams, and Slack are end-to-end encrypted for content -- but their metadata (who you call, when, for how long) is visible to your network. A VPN hides this metadata from your ISP and local network. This matters for sensitive business calls where even the existence of a conversation with a particular client or partner might be confidential.

Getting Set Up for Secure Remote Work with Nexun

Install Nexun on your work device -- available for Android and Windows. Enable the kill switch feature, which blocks all internet traffic if the VPN connection drops unexpectedly, ensuring your real IP is never exposed during a connection interruption. Use the Chrome extension for browser-based work tools while keeping desktop apps connected via the main application. Together, these give you comprehensive coverage without noticeable performance impact.
