Why Trust IAP is a “VPN Killer”: A Comparison of Access Technologies

Trust IAP vs. Traditional VPN: Evolution in Secure Access

In the era of total digitalization, when corporate data and resources are becoming increasingly vulnerable, ensuring secure access to them is a top priority. Traditional VPNs, long the standard in this area, are gradually giving way to new, more efficient, and secure solutions. Trust IAP (Identity-Aware Proxy) is an innovative technology that offers a fundamentally different approach to organizing secure access. Let's take a detailed look at why Trust IAP is a serious competitor to traditional VPNs and, in some scenarios, can offer significant advantages.

The Problem of Privilege Escalation Within the Network: Zero Trust Approach

Traditional VPNs create a secure tunnel between the user's device and the corporate network. After successful authentication, the user gains access to the entire network or a significant part of it. This can create certain risks: in the event of an account compromise, an attacker could potentially move around the network, gaining access to confidential data and resources not intended for their use.

Trust IAP, on the other hand, implements the Zero Trust concept. This means that no user or device receives automatic trust, even after successful authentication. Access is granted only to specific resources and applications necessary for performing job duties, and only after additional verification of identity and access context.

It is worth noting that modern VPN solutions also strive to implement Zero Trust principles and microsegmentation, offering functionality to restrict network access based on roles and policies.

Details of Zero Trust Implementation in Trust IAP

• Microsegmentation: Trust IAP divides the network into small, isolated segments. Access between segments is controlled by strict policies, which significantly limits the blast radius in the event of a compromise.
• Continuous Identity Verification: The user's identity is constantly re-verified throughout the session. This may include multifactor authentication (MFA), user behavior analysis, and other methods.
• Least Privilege: Users are granted only the minimum necessary privileges to perform specific tasks.
• Audit and Monitoring: All user actions are carefully logged and analyzed to detect suspicious activity.

Unlike some VPN solutions, where after establishing a connection, the user can gain access to a significant portion or the entire network, Trust IAP provides granular access control, significantly reducing the risks associated with privilege escalation within the network.

User Convenience: Clientless vs. Client-based

Another important advantage of Trust IAP is its ease of use. Traditional VPNs, such as Cisco AnyConnect or Fortinet SSL VPN, often require the installation of special client software on users' devices. This process can be complex and time-consuming, especially for untrained users. In addition, client software may be incompatible with some operating systems and devices.

Trust IAP is typically a clientless solution. This means that to access protected resources, the user only needs a regular web browser. No additional software or plugins are required. This significantly simplifies the connection process and makes it more user-friendly.

Advantages of Clientless Access

• Simplicity and Convenience: Users do not need to install or configure any software. Access is via a regular web browser.
• Compatibility: Clientless solutions work with most operating systems and devices that support a web browser.
• Reduced Support Costs: The absence of client software reduces the costs of user support and device management.
• Increased Security: Clientless solutions can reduce the attack surface because no additional software is installed on users' devices.

Imagine a situation where an employee needs urgent access to corporate email from a personal laptop or tablet. With a traditional VPN, this may require installing and configuring client software, which will take time and require certain technical skills. With Trust IAP, it is enough to open a web browser and enter your credentials. The difference in convenience can be significant.

Hiding Resources from External Scanning: The "Dark Network" Principle

Traditional VPNs, in some configurations, can open access to the corporate network, potentially making it visible to external scanning. However, modern VPN solutions provide tools to limit network visibility and protect against scanning.

Trust IAP implements the "Dark Network" principle. This means that protected resources are hidden from external scanning and are not visible from the Internet. Trust IAP acts as a proxy server that intercepts all incoming requests and redirects them only after verifying the user's authentication and authorization.

How the "Dark Network" Principle Works

• Inverted Access Model: Instead of opening access to the network, Trust IAP accepts only authorized requests and redirects them to protected resources.
• Hiding Infrastructure: Corporate infrastructure is hidden behind Trust IAP and is not visible from the Internet.
• Protection Against Scanning: Trust IAP blocks attempts to scan and enumerate resources.
• Minimizing the Attack Surface: Hiding resources significantly reduces the attack surface and reduces the likelihood of successful penetration by attackers.

Imagine that your company uses a web application to manage a customer database. With a traditional VPN, without additional security measures, this application could potentially be accessible from the Internet, and attackers could try to find vulnerabilities and gain access to confidential customer data. With Trust IAP, this application will be hidden behind a proxy server, and attackers will not even be able to know of its existence.

Detailed Comparison of Access Technologies: Trust IAP vs. Traditional VPN (Cisco/Fortinet)

For a clearer comparison, let's look at the main characteristics of Trust IAP and traditional VPNs in a table. It is important to note that the functionality of VPN solutions is constantly evolving, and the table reflects general trends, not the absolute capabilities of each specific product.
