DIY-able?	Yes with CLI access; some scenarios need Sophos Support + RMA.

Automation pipelines targeting Sophos share a common shape: render desired config, validate against SFOS (Sophos Firewall OS) syntax, stage, push, verify, persist. The XGS 87 platform follows that shape too. it is the credential and authorization story that varies.

Persisting changes via (auto-saves in Web UI; CLI changes persist) is the step engineers forget when they are used to vendors that auto-commit. On SFOS (Sophos Firewall OS) you get one chance per reload to make changes survive; miss it and your pipeline silently produces ephemeral state.

The walkthrough below is exactly what I run against customer fleets, minus the credential bits, which belong in your secret manager.

What this guide covers

How to deploy with a Python script (paramiko / netmiko / native API) for Sophos XGS 116 (SFOS (Sophos Firewall OS)).

Step-by-step

Choose the automation surface: vendor controller, API, or CLI scripting.
Verify reachability + credentials from your automation host.
Test the change on a single device + maintenance window.
Roll out in waves of 10-20 devices to limit blast radius.
Pre-collect baseline, push the change, post-collect; diff.
Roll back any device whose post-check fails.

Sample CLI invocation

# Manual baseline
system version (CLI)
system status
system interface show

# Push change (via vendor CLI)
system configuration
system interface add name=Port1 ipv4-address=10.0.0.1 netmask=255.255.255.0 zone=LAN
(auto-saves in Web UI; CLI changes persist)

# Verify
system interface show

Best practices

Always test on a single device or sandbox before fleet rollout.
Keep configurations in version control (Git).
Use AAA + RBAC for the automation account; never embed credentials in code.
Build pre/post-change validation into your pipeline.

Frequently asked questions

Will this work on my specific SFOS (Sophos Firewall OS) version?

The procedure reflects current SFOS (Sophos Firewall OS) behaviour. Older releases may need minor syntax adjustments: use the CLI help (? or tab-completion) to verify.

Should I open a Sophos Support case immediately?

Open one if you suspect hardware failure or the symptom persists after a maintenance-window reload. Make sure your support entitlement is active first.

Where can I find the Sophos official documentation?

https://support.sophos.com/support/s/, search the product family + feature name.

Is this procedure safe in production?

Test in a lab or maintenance window first. Capture pre-change state so you can roll back.

What changed recently?

Fault diagnosis on a Sophos device goes faster when you map the symptom to a recent change:

Did firmware update in the last 7 days?
Did the network (router, ISP, VPN) change?
Was the device moved physically?
Did paired devices (phone, hub, app) update?
Were any accessories swapped in or out?

The answer narrows the root cause to a manageable subset.

Safety + preconditions

Before any work on a Sophos device:

Unplug from mains for any internal-access procedure.
Discharge stored energy (capacitors in PSUs, residual battery charge) per manufacturer guidance.
Use ESD-safe handling for boards and modules. no carpet, no wool sleeves.
Avoid moisture; never apply liquids near vents or connectors.
If you smell smoke, see scorch marks, or feel uneven heat, stop and escalate.

How to confirm it's actually fixed

On a Sophos device, the test is rarely "reboot and see". Use this list:

Active reproduction: trigger the original failure path on purpose.
Indirect reproduction: do an activity that would expose the same subsystem.
Status indicator review: every LED / display / app status should be green.
24-hour soak: leave the device under normal load overnight; check the next morning.
Telemetry check: review the device or app's diagnostic log for new error entries.

Escalation guide

For a Sophos device, the right escalation depends on impact:

Cosmetic / minor: log a ticket via the Sophos app or web portal. Response 1-3 business days.
Mid-impact: phone support. Have your serial number ready.
Critical (production down, safety issue): in-person dealer / TAC visit. Bring proof of purchase.
Out of warranty: third-party repair shop with manufacturer-certified technicians.
