Managing non-human identities like CI/CD pipelines, automated scripts, or microservices can be a challenge when using traditional bastion host setups. Bastion hosts have long been relied on to control and monitor secure access to sensitive systems. But as environments scale and automation grows, this approach starts showing its limitations.
This post will explore a modern alternative to bastion hosts for handling non-human identities—one that delivers better scalability, enhanced control, and increases overall productivity across your team.
The Gaps in Bastion Host-Based Approaches
A bastion host serves as a “gatekeeper,” filtering SSH or RDP access to your infrastructure. But when it comes to non-human entities, traditional bastion hosts create new problems:
1. Manual Credential Management
Non-human identities operating through a bastion host often require credentials. These credentials need to be generated, stored, rotated, and revoked. This process can become tedious, error-prone, and risky, especially if secrets aren’t handled securely.
2. Scaling Adds Complexity
As systems grow, managing hundreds or thousands of automated scripts and services through a bastion host strains resources. You often end up juggling key management tools, access policies, and logging setups, which can slow your team down. It creates unnecessary overhead for what should be a streamlined workflow.
3. Auditing Challenges
Bastion hosts generally log access activity, but distinguishing between human and non-human actions in audit trails can be cumbersome. This lack of granular identity tracking makes it harder to trace potential issues back to their origin.
A Modern Alternative: Identity-Aware Solutions
Replacing bastion hosts with an identity-aware approach simplifies how your organization handles non-human entities. Instead of funneling access through a single gateway, every identity—whether human or non-human—can operate with its own well-defined permissions and credentials.
