New in 3.3: hardware addresses and vendors are back on macOS 27, and more devices get a name from what they announce. Try Guardian free for 1 week.
Know when something on your network changes. PingKit Agent lives in your Mac's menu bar and, while your Mac is awake, discovers every device on your network, can alert you when one joins or goes offline, and tracks your SSL certificates. Uptime Watch keeps checking your sites from PingKit's servers even while your Mac is off.
NETWORK MONITORING:
- Discovers devices using TCP, Bonjour, SSDP, WS-Discovery, and CoAP
- Classifies devices automatically into IoT, Entertainment, Work, Infrastructure, and Family
- Tracks online/offline status with a full event timeline
- Runs scheduled speed tests and logs performance over time
- Checks gateway and internet connectivity every 30 to 60 seconds
- Per-device security scoring with 55+ detection rules
8 DIAGNOSTIC TOOLS:
Speed Test, Ping, Traceroute, Port Scanner, DNS Lookup, Security Scan, Wake-on-LAN, and My Network, all built in.
WI-FI DETAIL ONLY A MAC CAN SHOW:
Signal strength in dBm, noise floor, signal-to-noise ratio, channel, band, and negotiated transmit rate, read straight from the Wi-Fi radio, which iOS does not expose.
SMART ALERTS:
Get notified when your internet drops and, after a first day learning your network, when a new device joins. Switch on Device Offline to hear when a known device goes offline too.
GUARDIAN: MONITORING AND ALERTS
- Uptime Watch: 10 websites or TCP ports checked every 5 minutes from PingKit's servers, even while your Mac is off, with keyword checks and down/recovered alerts.
- Cert Monitor: 5 domains, with alerts 30, 14, 7 and 1 day before expiry.
- A morning briefing on your iPhone: what joined, what went offline and any outage while your Mac was awake.
- Wake from anywhere: with Guardian on your iPhone, ask this Mac to wake a computer at home while you are away, or run a scan or speed test from anywhere.
- Apple Private Cloud Compute answers the questions the model on your Mac cannot hold on its own.
GUARDIAN PLUS: ADVANCED MONITORING
- Cert Monitor: 50 domains, and alerts immediately on chain failures.
- Alerts by email, with a summary every Monday, or to a webhook.
- Sleep, restart and shut down your Macs and Linux machines over SSH, and wake them on a schedule.
- 90 days of history on your iPhone.
- ISO 27001 Compliance PDF with an Ed25519 signature, and an AI summary of your network's history.
DEVICE INTELLIGENCE:
Identifies devices by vendor (20,000 OUI manufacturers, where macOS provides the hardware address), Bonjour services, SSDP/UPnP metadata, open ports, SSH banners, HTTP headers, and hostname patterns, on your Mac.
PRIVACY FIRST:
Scanning and device identification happen on your Mac. AI answers are written on your Mac, or by Apple Private Cloud Compute, where possible; before PingKit's own service receives anything, PingKit asks your permission, and it never receives the device names you have set, hardware addresses, your network name or your public IP address. Monitoring data syncs through your iCloud. No accounts, no advertising, no third-party analytics.
FREE, NO SUBSCRIPTION:
Device discovery and classification, the online/offline timeline, all 8 diagnostic tools, Wi-Fi detail and smart alerts. Cert Monitor and Uptime Watch each include one permanently free slot.
REQUIRES:
- macOS 15 (Sequoia) or later
- Local network access permission

Shortcuts and Siri actions, clearer Security and connection readings, and figures in your language.

- Each Security check row shows what that check found, in amber for a warning.
- The Gateway and Internet tiles turn orange when the connection is slow, and Cert Monitor shows Expired for a lapsed certificate.
- Speed figures, units and times read in your language, and the sidebar and columns fit longer translations.
