ZTNA vs VPN: Which Model Fits Today’s Enterprises?



As enterprises modernise their security architecture, they face an essential question: ZTNA or VPN? Which remote access security model is suitable to meet the current threat? The emergence of hybrid work has expanded the attack surface, and adversaries are targeting identity, endpoints, and gaps in network trust. Now is a good time for organisations to re-evaluate their legacy VPNs, which cannot provide security at the speed of the changing environment.

Why Traditional VPNs Fall Short

For a long time now, VPNs have been at the core of remote access solutions; however, these limitations expose organisations to unnecessary risks.
  • Implicit trust model - After the user is authenticated, they are granted access to the entire network, creating a significant opportunity for lateral movement.
  • Performance bottlenecks - By backhauling user traffic through a centralised gateway, the bandwidth consumed on the connection will reduce user productivity.
  • Poor scalability - Legacy VPN architectures cannot keep up with the level of agility that is required by globalised teams today.
  • Limited Visibility - The security team has no granular information about how users are behaving or their devices.
With today's advanced threats, these limitations have led to the security team's inability to provide a secure, manageable, and scalable solution for the VPNs they manage.

How ZTNA Delivers Stronger Remote Access Security

ZTNA approaches security differently from traditional approaches by establishing "zero trust" principles first and continuously validating everything. Some of the benefits of ZTNA are:
  • More granular, least-privileged access to your applications (and not the networks they reside on) minimises your exposure to attacks.
  • Continuous posture assessment using identity, confirming device health and use behaviour analytics are completed on an ongoing basis.
  • Scalability in the cloud is ideal for distributed enterprises and hybrid workforces.
  • Micro-segmenting your application access (and reducing lateral movement).
  • Improving user experience, as users will now connect directly to applications as opposed to using a VPN tunnel for routing to applications.
ZTNA also aligns with Cybersecurity Mesh Architecture principles, so it is an excellent strategic enhancement for most modern enterprises.

Choosing Between ZTNA vs VPN: How to Get it Right?

When you want fast, stable, and secure access for your users, there’s no better choice than ZTNA vs VPN. While VPNs can still be used for older systems, ZTNA will help prepare you for the future of work by aligning with both today's threat landscape and tomorrow's transformation requirements.

Things to Look For in a Data Privacy Management Software

Image
Data privacy is a critical concern for businesses and organizations in today's digital age. With the rise of data breaches, regulatory requirements, and consumer demand for transparency, having a robust data privacy management software is essential. However, choosing the right software can be challenging. Here are the key features to consider when selecting a data privacy management solution. 1. Compliance with Regulations A good personal data privacy management software should help organizations comply with global privacy regulations such as the General Data Protection Regulation (GDPR), California Consumer Privacy Act (CCPA), Health Insurance Portability and Accountability Act (HIPAA), and other regional laws. The software should provide automated compliance tracking, reporting, and updates on regulatory changes to ensure your organization stays compliant. 2. Data Discovery and Classification Understanding where your sensitive data is stored is crucial for data protection. The s...

What Are ZTNA Solutions, and How Do They Secure Remote Access to Networks in India?

Image
With the rise of remote work, businesses in India are facing new cybersecurity challenges. Traditional VPNs and perimeter-based security models are no longer sufficient to protect sensitive corporate data from cyber threats. This is where Zero Trust Network Access (ZTNA) solutions come into play. ZTNA is a modern security approach that ensures only authorized users and devices can access company networks, reducing the risk of unauthorized breaches. In this blog, we’ll explore what ZTNA solutions are and how they help secure remote access to networks for businesses in India. What Is Zero Trust Network Access (ZTNA)? ZTNA is a cybersecurity framework that follows the principle of "never trust, always verify." Unlike traditional security models that assume users inside the network can be trusted, ZTNA requires continuous authentication and authorization before granting access to applications and data. This ensures that only verified users and devices can connect to business reso...
