Compare OSSEC vs. Splunk Enterprise vs. Suricata

OSSEC is completely open source and available at no cost, allowing users to customize its functionalities through a wide range of configuration settings, including the addition of personalized alert rules and the creation of scripts to respond to incidents as they arise. Atomic OSSEC enhances this capability by assisting organizations in fulfilling specific compliance standards like NIST and PCI DSS. It effectively identifies and notifies users of unauthorized alterations to the file system and any malicious activities that could jeopardize compliance. The Atomic OSSEC detection and response system, built on open-source principles, enriches OSSEC with thousands of advanced rules, real-time file integrity monitoring (FIM), regular updates, software integrations, built-in active response features, a user-friendly graphical interface (GUI), compliance resources, and dedicated professional support. This makes it a highly adaptable security solution that combines extended detection and response (XDR) with compliance capabilities in one comprehensive package. Its flexibility and thoroughness make it an invaluable tool for organizations aiming to bolster their security posture while maintaining compliance.

The Suricata engine excels in real-time intrusion detection (IDS), inline intrusion prevention (IPS), network security monitoring (NSM), and offline packet capture (pcap) processing. It analyzes network traffic using a robust and comprehensive set of rules and signature languages, complemented by advanced Lua scripting capabilities that allow for the identification of intricate threats. Its compatibility with standard input and output formats such as YAML and JSON simplifies the integration with various tools, including established SIEMs, Splunk, Logstash/Elasticsearch, Kibana, and other databases. The development of Suricata is driven by a vibrant community focused on enhancing security, usability, and efficiency. Additionally, the project is managed and endorsed by the Open Information Security Foundation (OISF), a non-profit organization dedicated to fostering the ongoing development and success of Suricata as an open-source initiative. This commitment not only ensures the software's reliability but also actively encourages community contributions and collaboration.
