A-Packets vs Scapy

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.

Scapy is a free Python packet manipulation program and library for forging or decoding packets, sending and capturing them, and matching requests with replies. It can run as an interactive shell or be used as a library. Listed tasks include scanning, tracerouting, probing, unit tests, attacks and network discovery. Users can set arbitrary field values and stack protocol layers rather than rely on predetermined templates; after a probe, Scapy returns full decoded packets before interpretation for further analysis. It can read and store pcap files, inject invalid frames and custom 802.11 frames, and be extended with protocols and add-ons. Scapy runs on Linux, macOS, BSD and Windows, though Windows installation requires Npcap. Optional plotting needs Matplotlib; TLS decryption and PKI operations need the cryptography package. The code, tests and tools use GPL v2, while the documentation uses CC BY-NC-SA 2.5. Documentation includes installation instructions, usage guides, troubleshooting and an API reference. The project supports only its latest master version, and critical bugs should be reported privately through GitHub’s security tab.
