Trust IAP vs. Google Cloud IAP: Which is Better for Hybrid Infrastructure?

Trust IAP vs. Google Cloud IAP: A Battle for Control in Hybrid Infrastructure

When it comes to ensuring secure access to applications and resources in a hybrid infrastructure, companies face a choice between various Identity-Aware Proxy (IAP) solutions. Two notable players in this field are Trust IAP and Google Cloud IAP. Both offer centralized authentication and authorization, but they differ in their capabilities, flexibility, and suitability for different scenarios. Let's examine these differences, focusing on three key aspects: cloud dependency, support for non-HTTP protocols, and flexibility in configuring policies for on-premise resources.

Cloud Dependency (Vendor Lock-in)

This aspect is perhaps one of the most important when choosing an IAP solution, especially for organizations actively using a hybrid infrastructure.

Google Cloud IAP: Integration with Google Cloud Platform

Google Cloud IAP, as the name suggests, is integrated with the Google Cloud ecosystem. This means that using it may require resources hosted in Google Cloud or integration with Google Identity Platform services.

• Advantages of integration with Google Cloud: If your infrastructure is primarily based on Google Cloud, integration is simplified. You can use existing Google Cloud Identity and Access Management (IAM) tools.
• Potential disadvantages: Possible dependence on Google Cloud and their pricing policies. Migrating your applications and resources to another cloud platform or back to an on-premise environment may require effort. In addition, the performance of Google Cloud IAP may depend on the availability and stability of Google Cloud.

Trust IAP: Independence and Flexibility

Trust IAP is designed with independence from a specific cloud provider in mind. It can be installed and run in various environments, including:

• On-premise data centers
• Public clouds (AWS, Azure, Google Cloud, and others)
• Hybrid environments

This gives organizations greater flexibility in architecture and avoids being tied to any one cloud service provider.

• Advantages of independence: The ability to deploy Trust IAP in any environment allows you to choose the most suitable infrastructure for your applications and resources, without being limited by the capabilities of a specific cloud provider. You can also migrate your applications and resources between different environments without having to make significant changes to the IAP configuration.
• Flexibility in choosing Identity Provider (IdP): Trust IAP supports integration with a wide range of Identity Providers (IdP), including Active Directory, Azure AD, Okta, Ping Identity, and others. This means you can use your existing identity and access management system without having to switch to a new solution.

Support for Non-HTTP Protocols

Modern hybrid infrastructures often use applications and services that operate on protocols other than HTTP(S). These can include SSH, RDP, databases (MySQL, PostgreSQL), and others. Support for these protocols is important to ensure complete protection of the entire infrastructure.

Google Cloud IAP: Non-HTTP Support

Google Cloud IAP is designed to protect web applications that run on HTTP(S) protocols. Support for non-HTTP protocols can be implemented using additional solutions.

• Tunneling: One way to provide access to resources running on non-HTTP protocols is to use tunnels, such as SSH tunnels. However, this can add extra complexity and reduce performance.
• Third-party solutions: Protecting non-HTTP protocols may require the use of third-party proxy servers or VPN solutions.

Trust IAP: Protocol Support

Trust IAP provides support for various protocols, including:

• HTTP(S)
• SSH
• RDP
• Databases (MySQL, PostgreSQL, MSSQL, and others)
• SMTP, IMAP, POP3
• And many others

This protects your applications and resources with a solution, simplifying management and reducing costs.Learn more about Trust IAP supported protocols

• Authentication and authorization: Trust IAP can integrate with existing authentication and authorization systems for non-HTTP protocols, providing secure access for users.
• Protection against protocol-level attacks: Trust IAP can analyze traffic at the protocol level to prevent attacks such as SQL injections, brute-force attacks.

Flexibility in Configuring Policies for On-premise Resources

For organizations using a hybrid infrastructure, it is important to be able to define and apply access policies to on-premise resources with the same flexibility as resources hosted in the cloud.

Google Cloud IAP: Limitations for On-premise

Google Cloud IAP is designed to protect resources hosted in Google Cloud. Applying policies to on-premise resources may require the use of additional solutions.

• Google Cloud Interconnect: Connecting on-premise resources to Google Cloud may require the use of Google Cloud Interconnect.
• Limited policy granularity: Google Cloud IAP may not provide sufficient policy granularity to meet the specific security requirements of on-premise resources.

Trust IAP: Control and Adaptability

Trust IAP provides control over access policies to on-premise resources, allowing organizations to define rules based on:

• User identity
• User role
• User location
• Device type
• Time of day
• And other factors.More about access policies

This allows organizations to implement Zero Trust policies, ensuring access to resources only if the necessary conditions are met.

• Adaptive policies: Trust IAP allows you to define adaptive policies that dynamically change depending on the context of access. For example, access to sensitive data may only be allowed from devices that meet certain security requirements, or only at certain times of the day.
• Integration with existing systems: Trust IAP can integrate with existing Identity and Access Management (IAM) systems, SIEM, and other systems, providing centralized management of security policies.

Conclusion: Choosing an IAP for Your Hybrid Infrastructure

The choice between Trust IAP and Google Cloud IAP depends on the needs and requirements of your organization.

• Google Cloud IAP: Suitable for organizations that use Google Cloud and need integration with existing Google Identity Platform services. However, non-HTTP protocol support and dependence on Google Cloud should be considered.
• Trust IAP: This may be the solution for organizations using a hybrid infrastructure and needing a flexible and cloud-independent IAP solution. Trust IAP provides non-HTTP protocol support, control over access policies, and the ability to integrate with existing security systems.

When making a decision, assess your current and future security, flexibility, and cloud independence needs. Consider cost, implementation complexity, and ease of management. Remember that choosing an IAP is an investment in the security and flexibility of your hybrid infrastructure.
