    PacketCapture Cropped

    Capturing network traffic packets provides insight into what's happening on your network - but you don't want just anyone to do it. Learn how to safely capture packets in this article.

    You're in the middle of troubleshooting some weird network or service issue, things just aren't right, the ports are open, the service is listening, but something is still off. Beyond verifying the basics, connectivity, ports, and running services, sometimes you just need to see what's going through the network. Stick around, and we'll talk about a few ways you can snoop on what's running across the wire, or up and down your application stack.
