A-Packets vs p0f

A-Packets analyzes PCAP and PCAPNG captures for incident response, forensics and protocol inspection. It reconstructs HTTP sessions, maps communicating hosts and services, examines wireless artifacts, extracts files, identifies credential exposure and flags suspicious events. The hosted analyzer accepts native capture files from tools such as Wireshark and tcpdump. Public analysis costs nothing, requires no signup and accepts uploads up to 25 MB, but the resulting page is public. Private workspace plans include reports and a REST API key: Starter Workspace (monthly) is $11.99 a month, Professional (monthly) is $24.99 a month, and Advanced (monthly) is $49.99 a month. Yearly workspaces are $99 a year, $199 a year and $399 a year, respectively. One-time packs cost $14.99 as a one-time purchase, $44.99, paid once or $99.99, paid once. Subscription analyses have permanent private storage; credit-pack reports are deleted after 30 days. OnPrem supports customer-controlled storage and air-gapped deployments, but analyzes captures case by case and does not decrypt TLS payloads, capture continuously or alert.
