Self-service first.
Opening Packet Lens Web
Sign in, then open Packet Lens from your account. Access comes with a Packet Echo Pro licence assigned to you, or a Packet Lens or Lens + Blueprint seat. If it sends you back to the account page, sign in again and retry.
Open Packet LensPacket Blueprint diagrams and exports
Diagrams are stored in your browser at blueprint.packetecho.net, so clearing site data removes them: keep a backup file. Members unlock exports by opening Blueprint from the account page; the unlock lasts seven days in that browser, offline included.
Unlock Blueprint exportsDownloading and installing
Packet Echo runs on Windows 10 and 11 from a signed installer. LLDP and CDP capture works without Npcap through Windows’ Pktmon, which needs the app to run as administrator.
