NetworkMiner vs Timesketch

NetworkMiner analyzes captured network traffic and can sniff live traffic, extracting artifacts such as files, images, emails, and passwords from PCAP files. It also builds a host inventory from IP address information for passive asset discovery and communication overviews. The free edition supports live sniffing and PCAP and ETL parsing on Windows and Linux, but not PcapNG parsing. Professional accepts PcapNG, Pcap-over-IP, and PacketCache data in addition to PCAP, ETL, and live sniffing, and exports results to CSV, JSON-LD, and XML. Its protocol features include file extraction across listed protocols, while VoIP support includes audio extraction from unencrypted calls. Professional also provides OSINT lookups for hashes, IP addresses, domains, and URLs. NetworkMiner does not decrypt HTTPS or other TLS-encrypted sessions. Extracted data stays on the end-user device rather than in the cloud. The source code is GPLv2 free and open source. Netresec warns that opening PCAPs can automatically extract malware and recommends Linux or Windows Sandbox to reduce self-infection risk.

Timesketch is a free, open-source tool for collaborative forensic timeline analysis. A sketch normally represents one case and can contain multiple timelines, views, comments and stories. Investigators can search and filter timelines, inspect data in charts and save discoveries as views. Sketches may be private or shared with individuals, groups or all system users. Supported imports include Plaso storage files, CSV, JSON, JSONL, Pandas DataFrames, Python dictionaries and spreadsheet files. Python analyzers run in background workers to enrich events, add tags or create saved views; documented integrations include Sigma, Google Safe Browsing, BigQuery, Yeti and HashR. Sigma support is marked alpha with known performance and functionality issues. Timesketch offers a web interface, REST API and command-line client. Docker is the only tested and actively maintained installation method; documentation calls for Ubuntu 22.04 and at least 8 GB of RAM. Indexes depend on physical disk space, and searches may fail above 150 indices in a timeline. The self-hosted plan is free.
