Fleet automation on Sophos works best when you treat SFOS (Sophos Firewall OS) as immutable infra: declare desired state, push, verify, rollback on drift. The XGS 87 family is well-suited to this because the config model is consistent across software trains.

Use (auto-saves in Web UI; CLI changes persist) explicitly: relying on auto-persist is one of those things that works fine until it does not, usually during a reload at the worst possible time.

The runbook below is the same shape I use in production. Read it once end-to-end before adapting; do not cherry-pick steps.

What this guide covers

How to back up configs nightly to a Git repo for Sophos XGS 87 (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.

Why this matters for your day-to-day

A Sophos device that's misbehaving costs more than the fix itself: lost productivity, missed calls, security risk, even safety risk in some categories. Treating the symptom quickly with a documented procedure is cheaper than letting it persist. The steps above are written to get you back to working in under an hour where possible, and to flag clearly when escalation is the right call.

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.

Verification checklist

After applying the fix on your Sophos device, confirm:

The original symptom is no longer reproducible.
Related features (status LEDs, app sync, paired accessories) still work.
The device responds to a soft reboot without the fault returning.
Any error codes that were on display have cleared.
Documentation (your service log, the brand companion app) reflects the change.

When to call Sophos support instead

Escalate if:

The same symptom returns within 24 hours of a clean fix.
You see physical damage (burn marks, swollen battery, cracked PCB).
The device is in warranty and a hardware replacement is the cheaper outcome.
Repair requires specialised tools you don't own (alignment jigs, calibration software).
Following the official path keeps the warranty intact, which matters more than the time spent.
