To make WFH possible, businesses must ensure their remote employees can access internal apps and business data from anywhere, anytime. This may seem logical but it does raise some concerns related to trust, such as the mishandling or sharing of confidential data like customer information by remote employees. Such unfortunate incidents could be detrimental to a company's bottom line and reputation. To tackle this, businesses are considering the use of solutions like **Zero Trust Network Access (ZTNA) and Virtual Private Network (VPN)**, but many of them are still unsure as to which one best suits their use case and requirements.

Let’s clear up this confusion!

## What is ZTNA? {#what-is-ztna}

**Zero Trust Network Access (ZTNA)** is a security solution that helps businesses set policies that require users, whether working remotely or from the office, to verify their identity before accessing any application or business data. It follows the principle of "never trust, always verify," meaning access is only given after evaluating factors like:

- User identity
- Device security
- Group or user role in the organization
- Geolocation, etc.

ZTNA dynamically grants access to specific apps or data that employees need at a given time. This access is immediately revoked once the session ends.

In short, **Zero Trust Network Access** allows organizations to selectively and securely provide access to their applications and resources without exposing their entire network. This is where zero trust providers play a crucial role in delivering **ZTNA as a service**.

## What is VPN? {#what-is-vpn}

A VPN (Virtual Private Network) is a technology that creates a secure and encrypted connection between two networks or devices over the internet, providing remote access for distributed workforces. When a user connects to a VPN, internet traffic is encrypted and sent through a secure tunnel to a VPN server. This changes your IP address to match the VPN server's IP, hiding your identity and location. As a result, your data is protected from eavesdropping, and all business traffic can be inspected by security solutions, no matter its source.
However, as remote work becomes more common and businesses rely more on cloud-based apps, VPNs are struggling to keep up compared to modern **Zero Trust Network Access solutions**.

|---------------------------|------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------|
| **Security Posture**       | Continuously verifies users, devices, and access levels, limiting exposure to sensitive resources.    | Provides access to the entire network once a user is authenticated.                                                |
| **User Access Control**    | Allows users to only access specific apps or data they are authorized to use.                        | Grants wide-range access to all network resources once connected.                                                  |
| **Deployment Model**       | Primarily cloud-based, allowing for easier deployment, management, and updates.                      | Usually requires on-premises hardware or appliances, which can be cumbersome to deploy and maintain.               |
| **Remote Work Compatibility** | Built specifically for secure remote access, making it ideal for remote or hybrid work environments. | Designed for remote access but may not be optimized for large-scale remote or hybrid work setups.                  |
| **Scalability**            | Designed for dynamic environments and growing remote workforces.                                     | Limited scalability. Its performance can degrade with an increase in users.                                        |
| **User Experience**        | Simple and fast access to cloud apps.                                                                | Slower speeds due to encryption and tunneling processes.                                                           |
| **Cloud Integration**      | Integrates with cloud-based apps and services.                                                       | Integrates with on-premises network access; less optimized for cloud environments.                                  |
| **Performance Impact**     | Less performance impact due to app-specific access.                                                  | Impacts performance due to encrypted tunnels and high bandwidth usage.                                             |

## Limitations of VPN over ZTNA {#limitation-of-over}

Virtual Private Networks (VPNs) are often used by businesses for secure remote access, particularly in perimeter-based security models. However, VPNs have several limitations that make them less suitable for the security needs of modern businesses. Here are the main drawbacks:

- **No Cloud Support:**
VPNs are designed for secure remote access to corporate networks. However, they often struggle to support cloud-based apps like Google Workspace, Office365, and other resources outside the traditional network perimeter.
- **Network-Level Access Controls:**
VPNs provide access controls at the network level but lack visibility and control over individual applications. This means users may gain broad access to sensitive resources within various apps. If a cybercriminal breaches your VPN, they could easily access your confidential data.
- **Poor Support for BYOD Devices:**
Allowing employees to use their own devices (BYOD) to access the corporate VPN exposes the network to potential threats from unmanaged endpoints. Malware or other cyber threats can gain direct access to corporate resources.

## The ZTNA Advantage {#ztna-advantages}

**Zero Trust Network Access (ZTNA)** offers a different approach. It doesn't require users to connect to the corporate network. Instead, it verifies identity first and grants access afterward, allowing secure use of cloud apps over the public internet. This approach is ideal for remote-first companies, enabling employees to work securely from public spaces like cafes, airports, or anywhere else.

## Top Use Cases for ZTNA Solutions {#usecases-of-ztna}

### Remote Work Security
Zero Trust Network Access improves [remote work security](https://www.miniorange.com/casb/) by allowing employees to securely access the company’s network and resources from anywhere.

Zero Trust Network Access simplifies meeting [regulatory compliances](https://www.miniorange.com/compliances/) by ensuring only authorized users access sensitive data. This makes audits smoother and strengthens overall security. Imagine preparing for an audit; ZTNA provides clear records showing who accessed what, helping you pass with ease.

## Choosing the Right Enterprise ZTNA Solution {#enterprise-ztna-solution}

Most businesses start using the ZTNA strategy by applying it to a specific use case. At an early stage, it’s crucial to check if the chosen ZTNA solution can go beyond this initial use case and meet other current needs.

Before selecting a use case to pilot a **Zero Trust Network Access solution**, ask yourself these points:

- **Types of Apps Supported**: Does your ZTNA solution support all app types—legacy, Web3, cloud, etc.?
- **Server-Initiated Communication**: Do your apps require the server to initiate communication with the client?
- **Compatibility with IoT Applications**: Can the ZTNA solution handle IoT devices and provide unattended access?
- **Internet Policy Enforcement**: Should your ZTNA solution control internet access?
- **Secure Communication Across Data Centers**: Can it secure communications between data centers?

Work from home (WFH) remains a common practice for many businesses worldwide. This working model has enabled companies to hire top talent across borders, boost revenue, and improve employees work-life balance. A new report by Tata Consultancy Services (TCS) claims that, by 2025, 40% of employees around the world will work from home.  However, this growing trend also brings about a range of cybersecurity risks that could impact businesses significantly.
