Access Proxy Bastion Host Alternative

Bastion hosts have been a common solution for managing secure access to internal systems. They're designed as a gateway for safeguarding sensitive resources. However, managing and scaling bastion hosts introduces complexity, time overhead, and potential security challenges. Many teams are now reevaluating if there’s a better way to handle secure remote access.

Access proxies have emerged as a reliable and dynamic alternative to bastion hosts, solving many of their inherent limitations. In this blog post, we’ll explore why access proxies often serve as an ideal bastion host alternative and simplify managing secure connections to internal systems.

What is an Access Proxy?

An access proxy is a reverse proxy specifically designed to control access to internal services. Unlike bastion hosts, which rely heavily on SSH keys and manual user authentication management, access proxies streamline access by focusing on identity-based controls and smart automation.

Access proxies operate on principles of zero trust, requiring users to verify their identity and permissions before letting them access specific services. In practice, this approach removes much of the operational burden tied to managing traditional bastion hosts.

Why Replace Bastion Hosts with an Access Proxy?

1. Simplified Access Control

Bastion hosts rely on maintaining a complex web of SSH keys, VPN configurations, or user-specific firewall rules. When teams grow, or services become more distributed, managing these configurations can quickly get out of hand.

Access proxies, on the other hand, utilize centralized policies that are tied to identity providers like SSO systems or OAuth2. This simplifies user onboarding, offboarding, and permissions management across large teams without sacrificing security.

Key takeaway: With an access proxy, you can shift from managing individual credentials to more scalable identity-driven access.

2. Enhanced Security

Bastion hosts often present a single point of entry, which makes them a high-value target for attackers. Moreover, the frequent use of static credentials like SSH keys creates risks if those credentials are ever leaked.

Access proxies enhance security by eliminating static credentials and replacing them with short-lived, environment-specific tokens. Combined with methods like device posture checks, you get robust protection against unauthorized access and credential leaks.

Key takeaway: An access proxy reduces attack surface by replacing static credentials with tokenized, per-session access.

3. Zero Trust Implementation

Scaling bastion hosts often conflicts with implementing zero trust principles. Trust is implicitly granted to those who can authenticate at the bastion layer, regardless of additional factors.

Access proxies enforce strict zero trust policies by continually validating user identity, device status, and real-time access policies for every request. It ensures that access is granted dynamically based on who is requesting and their context, not just their credentials.

Key takeaway: An access proxy seamlessly integrates zero trust without adding operational complexity.

4. Operational Ease

Spinning up and managing a bastion host requires ongoing upkeep including patching, security hardening, and monitoring for potential attacks. Over time, the maintenance overhead increases, leading to operational inefficiencies.

Access proxies are designed to minimize operational overhead. They can integrate with your existing infrastructure and identity systems, often requiring little maintenance once configured.

Key takeaway: Access proxies are simple to deploy and reduce the long-term operational cost of managing secure access.

Common Use Cases for Access Proxies

Access proxies are particularly useful for:

• Granting engineers secure access to internal tools and dashboards over HTTPS
• Enforcing granular role-based policies across internal services
• Providing contractors or external partners temporary access to restricted environments
• Replacing VPNs or legacy access control methods that don’t scale securely

Moving Beyond Bastion Hosts

Access proxies represent the next step in secure access management. They provide improved scalability, stronger security, and simplified operations compared to bastion hosts. For teams looking to adopt zero trust principles without increasing complexity, access proxies are the clear answer.
