Flag an IP for proxy review in Slack
Use a simple reaction to move an IP concern into a focused check.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
IP2Proxy: Get Proxy Detection
Tool to detect if an IP is a proxy, VPN, or TOR exit node. Use when verifying anonymizing services.
Why this helps
Remembering which addresses need a security review can add another follow-up item to an already full channel.
- Mark an IP message for an anonymization check.
- Make the follow-up action visible in the conversation.
- Receive a run summary without manually opening a lookup tool.
Setup
Build it in a few focused steps.
- 1Connect Slack and Ip2location to Notis once.
- 2In the portal, create an automation with one plain-language instruction to check the IP in a reacted-to message for proxy, VPN, or TOR use.
- 3Choose Message Reaction Added as the trigger and select where run reports should appear.
- 4Test by adding the selected reaction to an appropriate IP message.
Questions about this workflow
Can I use this as a general security verdict?
No. IP2Proxy identifies proxy, VPN, or TOR use; it does not determine whether activity is malicious.
Can I focus it on one channel?
The reaction event supports optional channel filtering. Choose the appropriate trigger settings during setup.
