Find what is online
Discover hosts, open ports and service versions. Device identification combines evidence such as HTTP fingerprints, banners, MAC vendors and SNMP when available.
Open-source network auditing · 224 vendors · local lookups
Scan your local network from Linux or WSL2. SunsetScan finds devices and exposed services, then checks lifecycle evidence from 224 vendors using local data. Get a report that shows what needs attention and the vendor evidence behind it.
Free to try for noncommercial use · No account or EOL API required for scans
Current release v2.2.1 · Scanner code MIT · Hardware data CC BY-NC 4.0
What you get
Built for home networks and small IT teams that need more context than a port list. SunsetScan uses Nmap and local data to make device and service evidence easier to review.
Discover hosts, open ports and service versions. Device identification combines evidence such as HTTP fingerprints, banners, MAC vendors and SNMP when available.
Check for insecure services, common configuration issues, software end-of-life signals and CVE matches based on detected versions. Follow the evidence for each finding.
Compare detected models with manufacturer lifecycle evidence. Clear support endings stand out; incomplete vendor status is flagged for review.
Hardware lifecycle data
SunsetScan brings manufacturer lifecycle evidence into scans of routers, switches, cameras, NAS devices and related network gear. The database is installed locally, so a scan needs no online EOL lookup.
Manufacturer notices, support pages and product tables are mapped into one lifecycle model. The full validated database ships in the Debian package; smaller downloadable profiles are available for source installs.
Inspect the published database summaryIn our September 2026 check, SunsetScan covered 224 vendors; eol.network listed 55 and EOSL.ai listed 19. Explore the comparison ↗
The work behind the numbers
SunsetScan interprets vendor-specific terms, normalizes models and part numbers, removes duplicate entries and keeps unclear support claims marked for review. A discontinued label alone does not become a claim that security updates have stopped.
Why it matters
Network gear sits at the points where traffic enters, leaves and moves through a network. When its maker stops security updates, newly discovered flaws may remain open. An unsupported router at the network edge deserves priority. Replace unsupported network gear; restrict access and isolate it while replacement is under way.

See the output
See what SunsetScan reports for three network devices: a TP-Link lab result, an ASUS router that needs lifecycle review, and a Linksys router whose security support has ended.
See a TP-Link hardware lifecycle finding alongside exposed services, software EOL results and recommended actions. Generated with v2.1.1 in an authorized Linux lab.
The model appears in ASUS lifecycle data. SunsetScan flags it for review until firmware and security update status can be confirmed.
See the high severity hardware finding, Linksys support date, source and next steps in SunsetScan's v2.2.1 report.
Get started
Pick the install path for your Linux system, run setup once, then start a local scan. The Debian package includes the full validated hardware database. Installation downloads dependencies; scans use local caches afterward.
Download the package and checksum, verify them, then install.
