What is HAProxy Kubernetes Ingress Controller?

Fourteen patches into 3.2, and ssl-passthrough is still where the bugs are.

The controller is deep in the 3.2 patch line, shipping roughly every two weeks with no new configuration surface since the series opened. Four of the last six releases touch ssl-passthrough: resolving its mode before rules are built, reconciling its backends, and now keeping allow and deny lists attached to the https frontend. The rest is Kubernetes-object correctness — EndpointSlice handling, ingress merge ordering, duplicated backend config snippets.

What is Tailscale?

Tailscale ships AI control plane: Aperture GA manages LLM sessions, PAM adds privileged access

Tailscale crossed from pure network fabric into security control plane territory in August. Aperture reached GA with a full AI gateway feature set: rate limits, cost controls, request/response hooks, guardrails, MCP server support, and API proxying for major LLM providers. PAM (beta) adds application-aware privileged access with session recording for SSH, databases, Kubernetes, and RDP — capabilities that previously required a dedicated PAM product. Underneath both, version releases address a notable security vulnerability (TS-2026-011) and connectivity edge cases.

HAProxy Kubernetes Ingress Controller vs Tailscale: editorial side-by-side

H5.0

Fourteen patches into 3.2, and ssl-passthrough is still where the bugs are.

◆ Current state

The controller is deep in the 3.2 patch line, shipping roughly every two weeks with no new configuration surface since the series opened. Four of the last six releases touch ssl-passthrough: resolving its mode before rules are built, reconciling its backends, and now keeping allow and deny lists attached to the https frontend. The rest is Kubernetes-object correctness — EndpointSlice handling, ingress merge ordering, duplicated backend config snippets.

◆ Where it's heading

This is a stabilisation series, not a feature series. The recurring theme is that ssl-passthrough interacts badly with everything layered on top of it — access control, backend reconciliation, rule generation — and each release fixes one more intersection. Test coverage is now landing alongside the fixes rather than after them, which suggests the maintainers are treating the passthrough path as a known weak spot rather than a series of unrelated bugs.

◆ Prediction

Expect 3.2.x to continue at a two-week cadence with further ssl-passthrough intersections, and expect any new capability to wait for a 3.3 line rather than arrive in a patch.

Tailscale ships AI control plane: Aperture GA manages LLM sessions, PAM adds privileged access

◆ Current state

Tailscale crossed from pure network fabric into security control plane territory in August. Aperture reached GA with a full AI gateway feature set: rate limits, cost controls, request/response hooks, guardrails, MCP server support, and API proxying for major LLM providers. PAM (beta) adds application-aware privileged access with session recording for SSH, databases, Kubernetes, and RDP — capabilities that previously required a dedicated PAM product. Underneath both, version releases address a notable security vulnerability (TS-2026-011) and connectivity edge cases.

◆ Where it's heading

Tailscale is building upward from the network layer into security policy enforcement and AI infrastructure. The pattern — own the network, then control what travels over it — positions them against Teleport for developer PAM and Cloudflare AI Gateway for LLM proxying. The tailnet becomes the trust boundary, and both Aperture and PAM use it as the identity layer for access decisions.

◆ Prediction

Aperture and PAM will likely converge toward a unified policy surface: one place to govern both human privileged access and AI agent access, with the tailnet as the enforcement fabric. Expect Aperture to add per-model cost budgets and PAM to move toward GA with expanded service type support.
