Frequent Asked Questions

What is CloudShark?

CloudShark is a first of it’s kind web application that lets you organize, analyze, and collaborate on network packet captures.

CloudShark is a capture management system

CloudShark lets you secure and track valuable network capture assets. With tagging and search capabilities, all of your capture data is in one place that lets you find what you need when you need it.

In addition, the CloudShark API lets you easily integrate into your existing capture tools, letting you upload captures from anywhere, or by using the CloudShark Plug-in for Wireshark.

CloudShark provides browser based Wireshark functionality

CloudShark enhances the packet analysis process with web technology. With a comfortable, clean interface, it lets you perform common decode and analysis functions, embed and auto-lookup Wireshark filters, and perform faster, better looking, and more direct analysis of captures using tools like RTP playback, graphs, and controlled decryption.

CloudShark allows collaboration on packet captures

CloudShark lets you get to the root of network and application problems faster by facilitating collaboration with your colleagues and customers. Pass around URLs rather than large attachments, let others pick up where you left off, and add annotations and comments to packets and capture files.

How does a CloudShark online trial work?

If you sign up for our online version of CloudShark, you can try it free for 30 days. During that time, you can upload captures of up to 2MB in size.

Once you upgrade to a paid account, your captures can be marked as private.

CloudShark URLs are unique. Search engines will not index them unless they are included as links on another publicly available web page.
