Introduction
The shift toward remote and hybrid work has fundamentally changed how organizations think about network security. In a traditional office environment, security teams could rely heavily on a well-defined network perimeter, with firewalls, intrusion detection systems, and physical access controls all working together to protect a centralized corporate network. Remote work has dissolved that perimeter, scattering employees across home networks, coffee shops, co-working spaces, and countless other environments the IT department has no direct control over. VPN technology sits at the center of how most organizations have adapted to this new reality, but the specific tools and configurations that make sense for corporate security purposes differ substantially from the consumer VPN products individuals use for personal privacy. This edition of VPN Bulletin breaks down those differences and offers guidance for both employers and employees navigating this landscape.
What Corporate VPNs Are Designed to Do
A corporate VPN’s primary purpose is fundamentally different from a consumer VPN’s purpose, even though both rely on similar underlying encryption technology. Where a consumer VPN is designed to protect an individual user’s privacy and anonymize their general internet browsing, a corporate VPN is designed to create a secure, encrypted tunnel between a remote employee’s device and the company’s internal network resources, such as file servers, internal applications, and databases that are not meant to be accessible from the open internet at all.
This difference in purpose shapes many of the practical design decisions behind corporate VPN deployments. Corporate VPNs are typically configured with split tunneling disabled by default in higher-security environments, meaning all of an employee’s internet traffic, not just traffic destined for internal company resources, is routed through the corporate network and subject to the organization’s security monitoring and content filtering policies. This gives the security team much greater visibility into potential threats, such as an employee’s device attempting to communicate with a known malicious server, but it also means employees generally have less browsing privacy while connected to a corporate VPN than they would with a personal VPN, since their employer can typically see and log their general internet activity.
Identity and Access Management Integration
A defining feature of enterprise-grade corporate VPN solutions is their deep integration with an organization’s broader identity and access management systems. Rather than relying on a simple username and password, most modern corporate VPN deployments require multi-factor authentication and are tied directly into the organization’s single sign-on infrastructure, allowing security teams to enforce consistent access policies, quickly revoke access for departing employees, and maintain detailed audit logs of who accessed which systems and when.
Many organizations have also moved toward a zero trust network access model, which represents a meaningful evolution beyond traditional VPN architecture. Rather than granting a connected device broad access to the entire internal network once authenticated, zero trust systems evaluate each individual request for access to a specific application or resource, taking into account factors like device health, location, and behavioral patterns before granting access. This approach significantly reduces the potential damage from a compromised device or stolen credential, since access is granted narrowly and continuously re-evaluated, rather than broadly and only checked once at initial connection.
Where Personal VPNs Fit for Remote Workers
Even employees who use a corporate VPN for work-related tasks often maintain a separate personal VPN subscription for their non-work internet activity, and there are good reasons for this separation. A personal VPN protects an individual’s general browsing privacy, including activity that has nothing to do with their employer and that the employee reasonably does not want their IT department monitoring or logging, such as personal banking, private messaging, or simply browsing the web during a lunch break.
Personal VPNs also provide an important layer of protection specifically for the home and public networks that remote workers rely on but that fall entirely outside their employer’s direct security control. A home Wi-Fi network with outdated router firmware, or a public Wi-Fi network at a coffee shop, represents a genuine security risk regardless of whether a corporate VPN is also in use for work traffic, since the corporate VPN typically only protects traffic destined for company resources rather than encrypting the entire connection from the underlying network itself in a split-tunnel configuration. Running a personal VPN alongside a corporate VPN can add meaningful protection against local network threats such as packet sniffing on unsecured public Wi-Fi.
Common Security Gaps in Remote Work Setups
Despite widespread corporate VPN adoption, a number of common security gaps continue to affect remote work environments. One frequent issue is inconsistent enforcement of VPN usage policies, where employees are technically required to connect through the corporate VPN before accessing company resources, but face few practical barriers to bypassing this requirement when the VPN connection feels slow or inconvenient. Security teams that fail to pair VPN requirements with technical enforcement mechanisms, such as network access control systems that actively block non-VPN connections from reaching internal resources, often find that policy compliance in practice falls well short of policy on paper.
Another common gap involves split tunneling misconfigurations. While full tunneling, in which all traffic is routed through the corporate VPN, offers stronger security oversight, it can also create performance problems and user frustration, particularly for bandwidth-intensive tasks like video conferencing that do not need to be routed through the corporate network at all. Organizations that implement split tunneling without carefully defining which specific traffic categories should bypass the VPN risk inadvertently creating security blind spots, where sensitive traffic that should be monitored ends up being routed outside the corporate network’s visibility.
Device security represents a third significant gap, particularly in organizations that allow employees to connect personal, unmanaged devices to the corporate VPN. A VPN connection only protects the network traffic itself; it does nothing to address underlying device security issues such as outdated operating systems, missing security patches, or malware already present on the connecting device. Organizations with mature remote work security programs typically pair VPN access with device health checks, requiring a minimum security posture before granting network access, rather than treating the VPN connection as a security control in isolation.
Best Practices for Employers
Organizations looking to strengthen their remote work security posture should consider several practical steps beyond simply deploying a corporate VPN. Implementing multi-factor authentication for all VPN connections is a baseline expectation at this point, given how significantly it reduces the risk of credential-based compromise. Moving toward a zero trust access model, even gradually, offers meaningfully stronger protection than traditional broad-access VPN architectures, particularly for organizations with a large and growing remote workforce. Regular security awareness training that specifically addresses remote work risks, including the importance of securing home networks and avoiding risky public Wi-Fi usage, helps address the human element that technical controls alone cannot fully solve.
Best Practices for Remote Employees
Individual remote workers can also take meaningful steps to improve their own security posture. Always connecting to the corporate VPN before accessing any work-related resource, even when working from a trusted home network, ensures consistent protection regardless of network conditions. Securing the home network itself, including changing default router passwords and keeping router firmware updated, addresses a foundational risk that a corporate VPN alone cannot fully mitigate. Maintaining a separate personal VPN for non-work browsing helps preserve personal privacy while still meeting the security expectations that come with connecting to a corporate network, and using unique, strong passwords combined with multi-factor authentication for all work-related accounts closes off one of the most common avenues of compromise.
Special Considerations for Bring-Your-Own-Device Policies
Organizations that permit employees to use personal devices for work purposes, commonly referred to as bring-your-own-device or BYOD arrangements, face a particularly complex set of security tradeoffs when it comes to VPN deployment. On one hand, requiring a corporate VPN connection on a personal device gives the organization at least some visibility into traffic destined for company resources, which is clearly preferable to no security control at all. On the other hand, extending full corporate network access to a device the organization does not own, cannot fully audit, and often cannot enforce security patching or configuration standards on introduces meaningful risk that a purely device-agnostic VPN policy does not fully address.
Many organizations have responded to this tension by pairing BYOD VPN access with containerization or application-level virtual private network technology, sometimes called per-app VPN, which routes only traffic from specific, approved work applications through the corporate VPN tunnel, leaving the rest of the personal device’s traffic entirely outside the corporate network’s visibility. This approach offers a reasonable middle ground, providing meaningful security for company data and applications while preserving a clearer boundary around employee personal privacy on a device that also serves non-work purposes. Employees using their own device for both personal and work purposes should understand which specific policy their organization has implemented, since a full-tunnel BYOD VPN configuration carries meaningfully different privacy implications than a narrower, per-app approach.
Organizations without a formal BYOD policy at all, where employees informally use personal devices to access work email or documents without any VPN requirement whatsoever, face perhaps the greatest security exposure of all, since these connections typically bypass any centralized security monitoring entirely. Establishing at minimum a basic VPN or secure access requirement for any device touching company data, even informally used personal devices, represents a meaningful and relatively low-cost improvement to an organization’s overall remote work security posture.
Conclusion
Corporate and personal VPNs serve genuinely different purposes, and understanding that difference is important both for organizations designing remote work security policies and for individual employees trying to protect their own privacy and security while working outside a traditional office environment. As remote and hybrid work arrangements continue to be a permanent fixture of the modern workplace rather than a temporary adaptation, the tools and best practices covered in this article, from zero trust architecture to thoughtful BYOD policy design, will only become more central to how organizations and individuals think about network security.
