Gatekeeper vs Infisical: at a glance
What is Gatekeeper?
Gatekeeper grew a package manager for policies — and a benchmark to prove they are not too slow.
3.22.0-rc.0 in February introduced two CLI subcommands that change how policies are handled rather than what they express: gator policy, a brew-inspired tool for discovering, installing, upgrading and uninstalling policies from the gatekeeper-library, and gator bench, which benchmarks Rego and CEL engines with latency percentiles, throughput, memory profiling and baseline comparison for CI regression detection. The same release enabled sync-vap-enforcement-scope by default and gave both CEL and Rego access to namespace context during admission and audit. Since then, 3.23.0-rc.1 added status resource routing for remote cluster mode, and 3.24.0-beta.0 made generated ValidatingAdmissionPolicy output deterministic to stop a reconcile loop.
What is Infisical?
Infisical launches Agent Vault: credential-free secret injection for AI agents.
Infisical is shipping 10+ patch releases over two weeks, advancing three parallel fronts: Agent Vault (credential-free runtime secret injection for AI agents, now out of preview), PAM (privileged access with break-glass, Oracle and Snowflake managed targets, and one-to-many LDAP), and PKI (custom X.509 extensions, certificate audit logs, and license-gated enterprise features). The v3 UI migration is an ongoing background workstream touching nearly every console page without changing product surface.

Gatekeeper

Gatekeeper grew a package manager for policies — and a benchmark to prove they are not too slow.
◆ Current state
3.22.0-rc.0 in February introduced two CLI subcommands that change how policies are handled rather than what they express: gator policy, a brew-inspired tool for discovering, installing, upgrading and uninstalling policies from the gatekeeper-library, and gator bench, which benchmarks Rego and CEL engines with latency percentiles, throughput, memory profiling and baseline comparison for CI regression detection. The same release enabled sync-vap-enforcement-scope by default and gave both CEL and Rego access to namespace context during admission and audit. Since then, 3.23.0-rc.1 added status resource routing for remote cluster mode, and 3.24.0-beta.0 made generated ValidatingAdmissionPolicy output deterministic to stop a reconcile loop.
◆ Where it's heading
The centre of gravity is moving from the admission controller to the tooling around it. Policies are becoming artefacts you install from a library at a version, benchmark against a baseline in CI, and test before they reach a cluster — which is the lifecycle application code already has and policy generally has not. Underneath, the ValidatingAdmissionPolicy path keeps maturing as Gatekeeper hands more enforcement to the Kubernetes-native mechanism it now generates.
◆ Prediction
Remote cluster mode gained status routing but the entries describe only that piece, so how far multi-cluster enforcement extends is unclear from these notes. The releases in this window are all beta and release candidates, so a 3.24.0 stable is the near-term milestone.
Infisical
8.8INFRA · APIS
Infisical launches Agent Vault: credential-free secret injection for AI agents.
◆ Current state
Infisical is shipping 10+ patch releases over two weeks, advancing three parallel fronts: Agent Vault (credential-free runtime secret injection for AI agents, now out of preview), PAM (privileged access with break-glass, Oracle and Snowflake managed targets, and one-to-many LDAP), and PKI (custom X.509 extensions, certificate audit logs, and license-gated enterprise features). The v3 UI migration is an ongoing background workstream touching nearly every console page without changing product surface.
◆ Where it's heading
Agent Vault's arc is clear: from an external documentation link two weeks ago to a launch modal, stripped preview callout, and dedicated quickstart docs by September 18. The product addresses a specific blocker in enterprise AI deployments—the paradox where an AI agent needs credentials to fetch the credentials it needs to operate. PAM is expanding methodically, adding managed targets (Oracle, Snowflake) and enterprise access patterns (break-glass, LDAP fan-out) one release at a time, building the account-privilege layer that large organizations require before putting secrets management in the critical path.
◆ Prediction
Agent Vault will reach GA within a few releases given the docs overhaul, intro modal, and preview-callout removal already shipped. The INFISICAL_RUN_MODES flag introduced in v0.165.9 suggests work on a lighter deployment footprint—likely a mode tuned for edge or embedded agent environments—which would directly complement the Agent Vault pitch to teams deploying AI at scale.
