How to Use ScrubForge with ChatGPT for Network Troubleshooting

ChatGPT has become a surprisingly useful tool for network troubleshooting. It can explain why a BGP neighbor goes down, suggest why your IPsec tunnel keeps dropping, and help you spot misconfigurations in firewall policies that would take you an hour to trace manually.

The problem is the workflow. To get useful help, you need to share your config. And your config contains active VPN pre-shared keys, admin passwords, API tokens, and SNMP strings that are live right now on your production network.

ScrubForge solves exactly this: sanitize the config locally before it leaves your browser.

Why Pasting Raw Configs into ChatGPT Is Risky

When you paste a config into ChatGPT, you're sending that text to OpenAI's servers. Depending on your account settings and region, that data may be:

None of this is hypothetical — it's standard practice for most cloud services. A production firewall config containing live credentials does not belong on an external server.

The fix is not to stop using AI for troubleshooting. The fix is to sanitize first.

The ScrubForge + ChatGPT Workflow

This is the full procedure, start to finish.

Step 1: Export your config

Pull the running config from your device. On Cisco IOS: show running-config. On FortiGate: System > Configuration > Download. On most vendors there's a CLI command or web UI export.

Step 2: Open ScrubForge

Click the ScrubForge icon in your Chrome toolbar. It opens as a panel directly in your browser — no tab, no upload, nothing sent anywhere.

Step 3: Paste and sanitize

Paste your raw config into ScrubForge. It detects sensitive patterns — passwords, PSKs, API tokens, private keys, community strings — and replaces each unique value with a consistent token like [PSK_1], [ADMIN_PASS_1], [API_TOKEN_1].

Consistency matters: if the same password appears in five places, all five get the same token. ChatGPT can still reason about your config logically without seeing a single real credential.

Step 4: Review before pasting

Scan the sanitized output for anything that looks like a real secret. ScrubForge catches the common patterns, but configs can be creative. A quick 30-second review is good practice.

Step 5: Paste into ChatGPT with context

Now open ChatGPT and paste. Include a clear problem statement along with the sanitized config:

My IPsec site-to-site tunnel drops every 4 hours. Here is my sanitized running config
(credentials replaced with tokens — the config structure is intact):

[paste sanitized config here]

What should I check?

ChatGPT will analyze the IKE phase settings, DPD timers, and lifetime values without any of your live credentials in the conversation.

What ChatGPT Can Actually Help With

Once the config is sanitized and pasted, AI troubleshooting works well for:

ChatGPT can read structure and logic very well. What it doesn't need — and what you shouldn't provide — is working credentials.

Before and After: What Gets Replaced

Here's a Cisco IOS snippet showing what ScrubForge does:

--- BEFORE (Raw) ---
crypto isakmp key T@nn3lS3cr3t address 198.51.100.10
username netadmin password 7 094F471A1A0A
snmp-server community public RO
snmp-server community pr1vate_mon RW

--- AFTER (Sanitized) ---
crypto isakmp key [PSK_1] address 198.51.100.10
username netadmin password 7 [ENC_PASS_1]
snmp-server community [SNMP_RO_1] RO
snmp-server community [SNMP_RW_1] RW

The IP address stays. The interface names stay. The routing config stays. ChatGPT sees the same logical structure with none of the live credentials.

Other AI Assistants: Same Workflow

The same process applies if you prefer to use Claude, Gemini, or any other AI assistant. Sanitize with ScrubForge first, then paste the clean output anywhere. The credential exposure risk is identical regardless of which AI you use.

A Note on Memory and Training Opt-Outs

ChatGPT offers options to disable chat history and training in settings. These are worth enabling for work contexts. But they depend on your account settings being correct and OpenAI honoring those preferences server-side.

ScrubForge gives you a guarantee that doesn't depend on external settings: the credentials never left your machine in the first place.

Frequently Asked Questions

Does ScrubForge work with any type of network config? Yes. ScrubForge processes plain text, so it works with Cisco IOS, Juniper JunOS, FortiGate, Palo Alto, pfSense, and any other text-based configuration format. The detection targets common credential patterns, not vendor-specific syntax.

Can ChatGPT still understand my config if credentials are replaced? Yes. Network troubleshooting is about configuration logic, not credential values. ChatGPT cares about your IKE phase 1 settings, your routing protocol timers, and your policy order — none of which are credentials. The sanitized config provides everything needed for analysis.

What if I need to share the config with an actual vendor support engineer? Same workflow. Whether you're pasting into ChatGPT, emailing a Cisco TAC case, or posting in a community forum — sanitize first. Support engineers don't need your live credentials to troubleshoot your config; they need the structure.

Does the sanitization affect IP addresses? By default, ScrubForge targets credential patterns (passwords, keys, tokens), not IP addresses. Your network topology — addresses, subnets, peer IPs — remains intact in the sanitized output.

Is ScrubForge free to use? The core sanitization feature is free. Install from the Chrome Web Store and it works immediately — no account, no trial, no upload.
