NetworkMiner vs OpenGrep

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.

OpenGrep is a free, open-source static analysis engine for finding security issues and searching patterns in source code. It runs on Linux, macOS, and Windows, with self-hosted deployment. The project supports more than 30 languages, including Python, Java, JavaScript, Go, Rust, PHP, and Visual Basic, and existing Semgrep rules and rulesets work without changes. Its intrafile taint analysis tracks constructor and field assignments, flow between methods, higher-order functions across 12 languages, and collection operations such as map, filter, and reduce. OpenGrep produces JSON and SARIF output and documents a CI subcommand for workflow use. The project distributes self-contained binaries and says releases are signed with Cosign. OpenGrep is a Semgrep fork under the LGPL 2.1 license. The security policy requests vulnerability reports by email and lists only the latest version as supported.
