Discussion
20 comments analyzed.
Competitors mentioned: Teleport - for privileged access management and audit logging, Homebrew - for gaining legitimacy for CLI tools, Vanta/Anecdotes - for GRC evidence collection systems
Concerns raised: ACL policy tests insufficient for making changes fearlessly, Cannot test access to specific hostnames, only tags in policy tests, Lack of visibility into what's happening on the tailnet, Falls apart catastrophically when growing beyond highly competent teams, Missing audit trail and compliance features for medium/large organizations
Feature requests: External ACL tests or CLI command for ad-hoc reachability testing, Clearer guidance on using tags for user devices (laptop/phone with different permissions), Point-in-time compliance reports accessible via GUI and API, Continuous compliance monitoring via API for automated GRC systems, Better local observability into traffic patterns and access without heavyweight security product
