Coraza is an open-source, enterprise-grade, high-performance Web Application Firewall (WAF) ready to protect your beloved applications. It is written in Go, supports ModSecurity SecLang rulesets and is 100% compatible with the OWASP Core Rule Set. Coraza is a drop-in alternative to replace the soon-to-be abandoned Trustwave ModSecurity Engine and supports industry-standard SecLang rule sets. Coraza runs the OWASP Core Rule Set (CRS) to protect your web applications from a wide range of attacks, including the OWASP Top Ten, with a minimum of false alerts. CRS protects from many common attack categories including: SQL Injection (SQLi), Cross Site Scripting (XSS), PHP & Java Code Injection, HTTPoxy, Shellshock, Scripting/Scanner/Bot Detection & Metadata & Error Leakages. Coraza is a library at its core, with many integrations to deploy on-premise Web Application Firewall instances.

The OWASP ModSecurity Core Rule Set (CRS) is a curated, generic Web Application Firewall rule set that detects and blocks common attack categories across most web apps. It focuses on broad protection—SQL injection, cross-site scripting, local/remote file inclusion, command injection, and protocol violations—without requiring app-specific knowledge. Rules are organized into paranoia levels so operators can tune detection aggressiveness and balance false positives against coverage. An anomaly-scoring model accumulates rule hits per request, enabling nuanced blocking thresholds and easier incident triage. The project ships with extensive documentation, exclusion packages, and testing tools to help tailor deployment for frameworks, CDNs, and APIs. Deployed on engines such as ModSecurity or compatible WAFs, CRS is a widely used baseline for HTTP security in reverse proxies and gateways.

Stagemonitor is a Java monitoring agent that tightly integrates with time series databases like Elasticsearch, Graphite and InfluxDB to analyze graphed metrics and Kibana to analyze requests and call stacks. It includes preconfigured Grafana and Kibana dashboards that can be customized.

Lilith is a logging and access event viewer for Logback, log4j & java.util.logging. It has features comparable to Chainsaw for log4j. This means that it can receive logging events from remote applications using Logback as their logging backend

Kieker is a framework for continuous monitoring and dynamic analysis of distributed software systems. Being designed for continuous operation, it induces only a low overhead. The TraceAnalysis tool allows to analyze and visualize trace information.

The Amenetet Monitoring Service monitors remote services which register with it, heart beats are used in both directions to monitor the health of remote services. Remote services maintain a lease with Amentet and renew that lease regularly. Amentet then pings back to the remote service to monitor its health. Remote Services can monitor multiple objects internally, when "pinged" by Amentet, if any of these objects has disappeared an exception is thrown back with the list of missing objects. Amentet will store events in a local Db which can be viewed using the Web interface and as events occur alerts will be raised which can be sent to SNMP Trap daemon and/or SMTP and/or SMS. The service uses Spring Security Framework for access control and can be configured to use any Authentication Authorization system supported by the Spring Security Framework.

The Blindeye web application is a front end for the Blindeyes Distributed Command Framework. Blindeye will be specifically tailored towards the viewing and datamining of nmap scans.

CimStream is experimental implementation of the DMTF (Distributed Management Task Force) WBEM standard. The cimom is a java servlet, providing a secure, scaleable and high performance environment. Generated providers are strongly typed.

Alternative implementation of Spring framework remoting subsystem that supports different schemes of remote communication between client and server (1-1, 1-many, dynamic services discovering).

Commons-SSH is a thin bridge between different Java SSH implementations libraries. It doesn't contain any crypto-related code and created to be used by projects who doesn't want to care about export control regulations (let client to decide)

A firefox extension that resolves an eXtensible Resource Identifier (XRI) and renders the eXtensible Resource Descriptor Set (XRDS) document in a human-friendly interface.

Hyper-M is a bluetooth based DHT peer-to-peer infrastructure for J2ME (CLDC1.1/ MIDP2.0) enabled handphones. Hyper-M allows the user to create a peer-to-peer network and share and retrieve files on this network. Has been tested mainly on Nokia handphones

JPPF makes it easy to parallelize computationally intensive tasks and execute them on a Grid.

This software joins the power of NRPE with the flexibility of Java. JNRPE will give you the ability to call both old style native NAGIOS plugin and create new plugins with Java. Moreover, as of 2.0 JNRPE is embeddable in your own application.
