OSSEC

Business Profile

Core Value Proposition

OSSEC provides cross‑platform, open-source host intrusion detection (HIDS) that monitors logs, performs file integrity monitoring, detects malware, enables active responses, and supports compliance auditing.

Target Customer

Security teams, IT administrators, and developers seeking a free/open-source HIDS with optional enterprise capabilities for broader threat detection, response, and compliance across endpoints.

Key Differentiator

OSSEC branding as the official open-source HIDS with a clear pathway from free OSSEC to OSSEC+ (free with registration) and the enterprise-grade Atomic OSSEC, which adds machine learning, extensive rules, SIEM/EDR capabilities, a GUI, and professional support. It also positions itself as a long‑standing, multi‑platform solution with ready binaries (no compilation required).

Implementation Timeline

Immediate deployment possible with free OSSEC; ready-to-use binaries available (no compiling). Atomic OSSEC offers a 14‑day free SaaS trial and pricing starting under $5 per device per month for enterprise features.
