## Sister product

- [Noxen](https://noxen.app/): Mac-native nightly security audits of remote Linux/VPS fleets — SSH config, TLS, open ports, CVE matching, CIS/SOC 2/ISO 27001 evidence export. Built by the same team.

## Out of scope (explicitly)

- PingKit does not scan or audit remote Linux/VPS servers — that's Noxen's job.
- PingKit does not perform credentialed authentication against discovered services.
- PingKit does not exfiltrate network data; everything stays on-device or in your private iCloud database.
