In their own words
Arkime
Arkime is a free, open-source network analysis and session search tool that passively observes traffic and creates searchable session records. It parses layers 3–7 and indexes fields including protocols, DNS names, HTTP headers, TLS/JA4 fingerprints, file hashes, and GeoIP in OpenSearch or Elasticsearch. Operators can store full packets in standard PCAP format or use metadata-only capture, with rules to select traffic for saving. Users can search sessions, inspect packet data, and export results as PCAP or CSV. Cont3xt enriches supported indicators using commercial and OSINT sources, including VirusTotal, Censys, and Shodan; phone enrichment is limited to the U.S. Parliament groups clusters and displays cluster issues and Elasticsearch health. Capture can scale by adding machines or increasing CPU and disk. Arkime has no license fees or paid-only features. Installation guidance covers Linux, recommends Debian or Ubuntu LTS, and links to a container guide. OpenSearch or Elasticsearch is required for session metadata. Authentication options include basic, form, digest, header, and OIDC, while the project advises against anonymous authentication.
OpenGrep
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.
