What to send me

A short description is enough to start. If you can, include:

• Your network: which routers, switches or firewalls you use, and whether they can export IPFIX or NetFlow.
• Traffic volume: a rough estimate, for example average bandwidth or number of users.
• What you want to see: for example who uses the bandwidth, unusual traffic, or a security overview.
• Where it should run: an existing server or virtual machine, or a new one.
• Timeline: when you need it.

Please do not send passwords, access credentials or real traffic exports by e-mail or through the form. We will agree on a safe way to share access if it is needed.
