WYRE-AI EOL/EOS Flagging
Overview
End-of-life and end-of-support are two related but distinct events. End-of-life (EOL) generally means the vendor has stopped selling or actively developing the product. End-of-support (EOS) — sometimes called end-of-extended-support — means the vendor stops shipping security patches. EOS is the harder deadline operationally: a device past EOS is accumulating unpatched vulnerabilities with no fix coming, regardless of whether it still "works." This skill flags both, keeps them distinct in the output, and prioritizes the resulting list by how much it actually matters if a given device is left running past its date.
This needs two ingredients: device inventory data (make, model, OS version, firmware version — pulled live from whatever RMM is connected) and EOL/EOS knowledge (which dates apply to which OS/hardware — general knowledge, not something the RMM exposes). The two must be combined explicitly, and the knowledge half must always carry a verification caveat, because vendor lifecycle dates do change (extended support gets purchased, timelines shift) and this skill's knowledge has a cutoff.
This is distinct from warranty-tracking: a device can be fully in
warranty and past OS end-of-support (an aging laptop still under a 5-year
warranty but running an OS version no longer patched), or out of warranty
and still fully supported (an older desktop on a current, supported OS with
no active vendor patching risk). Both signals feed refresh-cycle-planning,
but they are not the same finding and should not be conflated in a report.
Anti-triggers
- Unsupported software as a scored patch/CVE finding — an out-of-support
OS surfaced with an EPSS score and exploit maturity is vulnerability
management; use
sentinelone-vulnerabilities. - A vendor's own end-of-life field — Auvik and ScalePad both record
lifecycle/EOL data natively; use
auvik-devicesorscalepad-lifecycle-managerwhen the question is what that tool holds rather than how to rank the risk across a fleet.
Discovering available tools first
Never assume which RMM is connected:
- Call
conduit__search_toolswith a query like"list devices","device details", or"OS version"to discover which RMM connector(s) are live and their real tool names (e.g.datto-rmm__datto_list_devices,ninjaone__list_devices,ncentral__ncentral_list_devices,atera__search_agents). - Pull make/model, OS name and version, and firmware version where exposed — the fields vary by RMM, so check what a given platform's device-detail tool actually returns before assuming a field exists.
- Cover all connected RMMs if more than one is present.
- Only call concrete tools that discovery actually returned.
Key Concepts
General EOL/EOS knowledge — with a verification caveat
This skill can reason about EOL/EOS timing for widely-deployed operating systems and hardware families using general knowledge (e.g., major desktop and server OS release/support lifecycles, common consumer/business OS version end-of-support windows, well-known network hardware firmware support windows). Use that knowledge to flag likely-EOL/EOS devices found in inventory.
Always attach an explicit caveat to any EOL/EOS date cited from general knowledge: state that the date should be verified against the vendor's current lifecycle page before it's used to justify a purchase or a hard deadline in front of a client, because:
- Vendors extend, shorten, or restructure support timelines.
- Paid extended-support programs can push a real deadline later than the "standard" EOS date.
- This skill's knowledge has a training cutoff and will not reflect lifecycle policy changes announced after that point.
Never present an EOL/EOS date with false precision or as independently verified fact — frame it as "generally documented as EOL/EOS around [date/quarter] — confirm against the vendor's current lifecycle page before treating this as final."
What counts as an EOL/EOS finding
Flag a device when any of the following is true, and say which applies:
- OS past end-of-support — the installed OS version no longer receives security patches from the vendor.
- OS approaching end-of-support — within a lookahead window (default 6 months if not specified) of its end-of-support date.
- Hardware/firmware past or approaching EOL — the device model itself, or its firmware, is past or nearing the vendor's stated end-of-life, independent of what OS it's running (relevant for network appliances, older server hardware).
Don't flag a device solely because it's "old" — flag it because a specific, named EOL/EOS date applies or is approaching. Vague "this looks legacy" judgments are not findings; a named date and source (general knowledge, caveated) is.
Prioritizing EOL risk by criticality
Not every EOL/EOS finding carries the same urgency. Combine the EOL/EOS signal with device role/criticality before ranking:
| Criticality | Examples | Why it matters more/less |
|---|---|---|
| High | Domain controllers, servers running production line-of-business apps, network appliances (firewalls, core switches), anything internet-facing | A patch gap here is a direct breach/outage risk with broad blast radius |
| Medium | Shared workstations, general-purpose servers with limited exposure | Real risk, narrower blast radius |
| Low | Spare/loaner desktops, rarely-used devices, kiosk-style single-purpose endpoints | Same EOL/EOS fact, much smaller practical exposure — still worth tracking, not worth panicking over |
Resolve criticality from whatever signal is available: device role/tags in the RMM (server vs. workstation), naming convention, or, where connected, a documentation platform's asset classification. If no criticality signal is available for a device, say so explicitly and default to treating it as unclassified rather than guessing — do not silently assume "low" to shrink the report.
A server past EOS ranks above a spare desktop past EOS even if the desktop crossed its date first — recency of crossing the date is a secondary sort key, criticality is primary.
Common Workflows
Portfolio-wide EOL/EOS sweep
- Discover connected RMM(s) via
conduit__search_tools. - Pull device inventory: make, model, OS version, firmware version where exposed.
- Apply general EOL/EOS knowledge (caveated) to classify each device: OS past EOS / OS approaching EOS / hardware past-or-approaching EOL / no known EOL/EOS risk / insufficient version data to assess.
- Resolve criticality per device from available RMM/documentation signals.
- Rank output: high-criticality + past-EOS first, then high-criticality approaching-EOS, then medium, then low, with the "insufficient data" bucket surfaced separately rather than dropped.
Single-client EOL/EOS check
- Discover tools and scope to the requested client/org unit/site.
- Run the same classify-and-rank steps, scoped to that client.
Error Handling
No RMM connector discovered
Say so explicitly: "No RMM connector is available through the gateway, so there's no device/OS inventory to assess for EOL/EOS risk." Do not fabricate device data.
OS/firmware version not exposed by the connected RMM
Report the device with "insufficient version data to assess EOL/EOS risk" rather than guessing a version from the device model alone.
Uncertain or disputed EOL/EOS date
If general knowledge is ambiguous about a specific date (e.g., a less-common OS build or a hardware model with a non-standard support timeline), say so plainly and recommend direct verification against the vendor's lifecycle page rather than presenting a guessed date as fact.
