Network automation

Routers and switches as a site: backups, drift, paths, a digital twin and safe rollouts.

A collector reads your Cisco, Huawei, MikroTik, FRR and VyOS devices and Zaryn keeps their configs as versions, draws the live map, explains why a path fails, tests a change on a digital twin before it is made, and rolls it out with automatic rollback.

Get started with network automation

A guided path from "what can Zaryn do for my network?" to safe, automatically checked changes: a read-only collector, config backups and drift, the live map, why A can't reach B, a digital twin that tests a change first, rollouts that undo themselves, and device access without shared passwords. Pictures first, every step explained.

⏱ About 40 minutes◔ From zero to advanced
  1. Stage 1Understand
    1. What Zaryn does for a network
    2. How it works
    3. What it reads, and what's free
  2. Stage 2Set it up
    1. Make a site and start the collector
    2. Logins, tried before they're used
    3. Add your devices
  3. Stage 3Every day
    1. Backups and drift
    2. The map
    3. The address plan
    4. What changed, when
  4. Stage 4Find problems
    1. Why can't A reach B?
    2. Watch what matters
  5. Stage 5Change safely
    1. Try a change on the twin
    2. Roll it out, with an undo
    3. One change, every device
    4. Device access without passwords

What you can do

  • Back up every config and see drift
  • Find why A can’t reach B, hop by hop
  • Test a change before it touches the network
  • Roll out changes with canaries and automatic rollback
  • Give temporary device access without sharing passwords

Pictures first, every step explained.
  2. 2Network sites (routers and switches)See your routers and switches live. Every config backed up and checked against the approved one, a map of how devices connect, and an address plan with its conflicts. Cisco, Huawei, MikroTik, FRRouting and VyOS.
  3. 3Path Explain and probesWhy can't A reach B? Zaryn follows the traffic hop by hop through your devices' routes, ACLs and firewalls, names the device and the rule that stops it, and gives the fix in that device's commands. Probes check what matters every minute.

Digital twin: test a change before you make it

See what a config change would do to your network before anyone types it. Which traffic stops, starts or takes another way and why, every routing table entry that changes, and the single points of failure it creates. On the site page, from the command line, and on every pull request.

Rollouts: make a config change safely

Make a config change on the devices themselves, checked on the live network and taken back by itself when the network doesn't hold. The exact commands both ways, the twin's verdict, approval with four eyes, waves with a canary, MikroTik safe mode and a dead man's switch on the device, every command and answer kept.
