Open your capture
Read .pcap and .pcapng files. See the capture’s devices, protocols, conversations, throughput and findings at a glance.
Packet Lens for the web
Packet Lens: analyze PCAP and PCAPNG files in your browserEvery packet has a story.
Open a capture, search a device, and follow the evidence to the conversation behind the problem. In your browser, with the capture analysed on your own machine.
Included with Packet Echo Pro: sign in and open it from your account.
Start with the question
Less decoding. More investigating.
A capture is only useful when it explains what happened. Packet Lens organises the evidence around the devices and conversations that matter.
Follow a device
Search by IP address, MAC address or hostname to focus the investigation, then move between its conversations and individual packets.
Check the evidence
Findings such as unanswered connection requests and retransmissions are ranked by impact, explained, and linked to the packets that support them.
Two ways to use it
In the browser, or in Packet Echo.
Same analysis, two places to run it. A Packet Echo Pro licence includes both.
Packet Lens Web
In your browserFor investigating a capture anywhere, with nothing to install.
- Open .pcap and .pcapng files
- Analysed in browser memory, never uploaded
- Sign in, open, drop the file
- $5 per person / month, or included with Packet Echo Pro
Capture Analysis in Packet Echo
Inside the Windows appFor larger local captures, beside the scan and switch evidence.
- The same analysis engine, as a Packet Echo workspace
- Streams the capture from disk
- Add findings to your session notes
- Part of Packet Echo Pro
Privacy by design
Your capture stays on your machine.
Packet Lens Web analyses the file in your browser. Packet data is not uploaded to an analysis service; your account is what opens the application, not what reads the capture.
The browser holds the capture in memory, so the memory you have available sets the practical file-size limit. For larger captures, use Capture Analysis in Packet Echo, which streams from disk.
- Try it with no private data: our sample capture is entirely synthetic, with documentation-range addresses.
Browser membership
Packet Lens Web
$5per person / month
For capture investigations without installing the Windows app.
- PCAP and PCAPNG analysis
- Device and conversation exploration
- Findings linked to evidence
