Virtual private networks (VPNs) have been a staple in providing secure remote access for many years. They create a secure tunnel between a user’s device and the corporate network, allowing access to internal resources. However, with the growing trend of mobile and cloud-based workforces, companies are recognizing the limitations of VPNs in this new hybrid world and are turning towards a more secure, user-friendly, and scalable solution – Zero Trust Network Access (ZTNA).
According to the 2024 VPN Risk report by Cybersecurity Insiders, a staggering 98% of businesses currently use a VPN service, with 92% of users accessing a VPN at least once a week. Despite the high usage, 56% of companies are exploring alternatives to traditional VPNs. Security concerns, poor user experience, and complex management are driving this shift, with 81% of users dissatisfied with their VPN and 65% of organizations having three or more VPN gateways to support.
The report emphasizes that a growing number of organizations (92%) are worried that VPNs could compromise their ability to secure their environments, prompting a shift towards a stronger security posture industry-wide.
The limitations and challenges associated with VPNs are clear, driving the transition towards ZTNA. VPNs, though offering a basic level of security, have inherent vulnerabilities that can be exploited by unauthorized users. Phishing campaigns targeting VPN credentials and vulnerabilities in VPN software pose significant risks to network security.
Managing secure access through a single VPN becomes increasingly complex as companies adopt cloud-based applications and services. The point-to-point connections required by traditional VPNs create logistical nightmares, especially when managing access to a growing number of cloud resources. Additionally, adding security solutions like multi-factor authentication to VPNs leads to a complex security stack, increasing the risk of misconfigurations and vulnerabilities.
The user experience with VPNs can also be challenging, with slow connections, compatibility issues, and constant login requirements affecting productivity. In contrast, ZTNA offers a more secure and streamlined approach by adopting a “never trust, always verify” principle. ZTNA provides granular access control based on user identity, device, location, and required resource, minimizing the attack surface and simplifying IT management.
While ZTNA offers significant benefits, implementing a zero-trust architecture requires careful planning and integration with existing security tools. Key considerations include planning and integration with identity management systems, as well as user training to ensure a smooth transition and strong security practices.
