Introducing CloudShark Threat Assessment

Use CloudShark to detect and analyze malware traffic in your network captures

Show me more


Drag and drop captures right into your browser, or upload using your personal API key. CloudShark organizes your captures so all of them can be named, tagged, and searched.


CloudShark's web-enhanced analysis and collaboration tools raise the bar on what you can learn from packet-capture data. Annotate packets, visualize protocol conversations, and build graphs - and link to it all with just a URL.


Instantly link to the work you've already done to share with co-workers or customers. They'll see exactly what you need them to see, and there's no need to email huge files to collaborate.

Perform deep packet analysis and share results through your web browser.

No software to install

CloudShark works entirely in your web browser. No additional utilities, plugins, or downloads.

Many Uses for CloudShark



Storing remote captures

Trying to debug a network problem or 3rd-party application? Post it to CloudShark and share it with others, use annotations to describe problems, and link directly to your analysis with just a URL.

Build a collection of example capture files for your blog, newsletter, or course materials. Readers can access advanced analysis from any device without needing any special software.

Need a centralized spot to store capture files from your servers, customers, or data-centers? CloudShark lives on the internet and can act like a drop-box for the files you generate while on the road.

All of the tools you need in one place.

  • Threat Assessment

    Detect and analyze malware traffic in your network capture files, collaborate with your team, and get to the root of evil.

  • Display Filters

    CloudShark supports all of the display filters in WireShark and helps you remember what they are by autocompleting as you type. The filter is automatically added to the URL for easy sharing.

  • Packet Annotations

    As you do analysis, save your thoughts and notes directly on the packets as you come across them. When you come back to the capture, the annotations will be there waiting.

  • Follow Stream

    View application layer conversations from TCP, UDP, and SSL streams. Link directly to the stream you're looking at to make shared troubleshooting even easier.

  • Protocol Ladders

    Trace protocols and conversations in a graphical representation of your capture files. Apply display filters, sort and hide nodes to get exactly the view that helps you.

  • Bandwidth Graphs

    Create detailed, informative and beautiful bandwidth graphs to explore network traffic. Browse, zoom, and view annotations all on a dynamic, configurable graphing system that lets you see exactly what's going on.

  • Merge & Extract

    Merge captures together, or break them apart! Take capture files from multiple locations or over a set of time periods and CloudShark can merge them together. Or go the other way and drill down into a large file to save only the packets you need.

  • VoIP & SIP Analysis

    CloudShark is the perfect tool for working with SIP conversations and VoIP call traffic. Use the built-in SIP Call Flow visual diagram for an easy to follow view of signaling between endpoints. Diagnose issues or confirm configurations by looking at the SIP headers, which are never more than a click away.

  • DNS Activity

    Diagnose DNS errors, timeouts, and unexpected behavior from your capture files. CloudShark breaks down DNS queries, responses, timing information and error codes and give you the ability to drill down to the packets slowing down your network.

  • IP GeoLocation

    See the top-talkers in your capture. Sort by the total number of packets or bytes received or transmitted. CloudShark ships with the GeoLite database from MaxMind to provide GeoLocation services on public IP addresses.

  • WiFi Decryption

    Easily decrypt and debug 802.11 traffic when you know the WPA/WPA2 passphrase. CloudShark lets you enter known WPA decryption keys for captured 802.11 traffic to decrypt data, management, and group keys.

  • Conversations

    Zero in on your top talkers, show client/server interactions, and discover unxpected sources of traffic. Conversations can be viewed at the MAC, IPv4/IPv6, or TCP/UDP application layer, and deliver the Follow Stream view for the chosen conversation with a single click.

  • Protocol Hierarchy

    Quickly get an answer to what kind of traffic your capture file contains or if one application is taking the majority of the bandwidth. This is often the first step when diagnosing problems within a network. Go from this view to filtering specific protocols with a single click.

  • RTP Playback

    Playback RTP audio from captured traffic without leaving your web browser. CloudShark is able to decode G.711, G.722, G.729, and GSM audio. Listen to VoIP calls to diagnose quality issues and drop-outs. Share audio with others without sending large files.

  • HTTP Requests

    HTTP Request analysis can help track down problems in your web application traffic or discover which websites are offering up what traffic to your users. CloudShark's HTTP Analysis tools let you drill down to the actual packets containing requests, and zoom out to see a high-level overview of response and error codes.

  • HTTP Object Extraction

    Reassemble and extract scripts, images, documents, and even videos from HTTP conversations within capture files. These documents can be previewed from inside of CloudShark, or downloaded for further offline analysis.

  • Wireless Networks

    Discover rogue access points, check for signal coverage, and analyze your BYOD deployment by analyzing raw wireless capture data. Inspect the easy to read list of SSID's, vendor information, signal-strentgh, and security profile information from WiFi Beacons and Probe responses in your capture.
