# How to Secure Third-Party Remote Access to Data Centers (Without SSH Keys)

**[Teleport](https://daily.dev/sources/teleport)** · 10 min read · 0 upvotes · 0 comments

## Summary

Third-party remote access to on-premises data center infrastructure often relies on shared SSH keys, VPN credentials, and standing privileges, creating credential sprawl and identity blind spots that attackers can exploit. Unlike cloud environments with native identity binding, on-prem systems lack equivalent identity-based controls. Recommended practices include just-in-time access with approval workflows, authenticating vendors through their own identity providers, issuing short-lived certificates instead of long-lived credentials, restricting access via label-based RBAC, automatically revoking privileges, and recording all sessions including kernel-level command capture via eBPF. Teleport is presented as a platform implementing this unified identity model across SSH, RDP, Kubernetes, databases, and cloud providers.

## Questions this post answers

### Why are shared SSH keys risky for giving vendors remote access to on-premises servers?

SSH keys are long-lived and not bindable to a specific task or time period, so they create persistent access and untraceable audit logs when handed to third parties. A 2026 infrastructure identity survey found organizations with high reliance on static credentials like SSH keys and API keys report a 20-percentage-point higher security incident rate (67% vs 47%) than those with low reliance.

_Teams weighing credential risk against vendor access needs can track identity security practices on daily.dev._

### Why isn't a VPN enough to secure third-party access to internal infrastructure?

A VPN places a user on the network but does not restrict which resources they can reach once connected, so a vendor needing one switch or database server ends up with access to an entire network segment. VPN authentication is also session-based rather than identity-based, meaning audit logs often show only that a tunnel was established, not which resources were accessed or what commands ran.

_Engineers scoping vendor network access follow infrastructure security patterns like this on daily.dev._

### What is just-in-time (JIT) access and how does it work for third-party vendors?

Just-in-time access means third parties have zero standing privileges by default; access to a resource must be requested, pass through an approval gate, and automatically expire when the task ends. This mirrors the cloud model of granting a temporary cross-account IAM role for a support engagement, and ties every session to a cryptographic identity for auditing rather than a shared credential.

_Anyone designing least-privilege vendor access workflows can dig into approaches like this on daily.dev._
