Legacy Systems

Secure AIX, CentOS, EOL Windows, HP-UX, RHEL; Address Compliance

If you can’t upgrade your equipment and software, you still have to protect these IT assets and meet compliance requirements. Secure your AIX, and legacy/unsupported end of life environments ranging from HP-UX, to RHEL 5, to Windows XP and Windows 2003, with Atomicorp.

Venerable systems such as AIX, Solaris, HP-UX, old versions of Red Hat like RHEL 5, Windows XP, and others, require a flexible endpoint protection solution, one that enables IT managers to secure and achieve compliance in hybrid cloud architectures consisting of legacy and modern systems.


Windows EOL

Our extended detection and response (XDR) system, Atomic OSSEC, secures Windows environments with comprehensive endpoint and cloud workload protection going all the way back to Windows XP. (See Table 1.)


Atomic OSSEC provides a log-based intrusion detection system (IDS), FIM, anti-malware, AES encryption, active response, and more for advanced AIX OS protection and compliance.

Red Hat EOL

Our XDR system provides log-based IDS, FIM, CVE scanning, active response and crypto for RHEL 5 and up, while enabling users of these systems to meet compliance requirements.

Ubuntu EOL

Supports Ubuntu EOL OS’s such as 16, 18 and their supported OS’s: Ubuntu 20, and 22. Atomic OSSEC detects and protects with endpoint and cloud workload protection including IDS, FIM, vulnerability detection and management, active response, AU controls, encryption, and security controls for compliance.


Is HP-UX still needed in your digital operations? Orchestrate AV, anti-malware, FIM, active response, and crypto across your HP-UX 11i systems—and achieve compliance.

Solaris EOL

Atomic OSSEC provides security support for Unix systems such as Solaris 11, including AV, malware detection, FIM, active response, AU controls, encryption, and meeting compliance requirements.


Security support for Centos 5, 6, and 7 features AV, anti-malware, FIM, active response, AU controls, encryption, compliance, and more.


Atomic OSSEC also secures and brings regulatory compliance for Internet of Things (IoT) Linux environments. This support ranges from AV, anti-malware, FIM, and AU, to encryption and active response.

macOS (Intel CPU versions) EOL

Atomic OSSEC protects these systems with endpoint security, including cloud workload protection, AV, FIM, active response, AU controls, AES crypto, and compliance (see Table 1).

Secure Legacy and EOL Systems with Versatile Endpoint Protection Solution

Security support for legacy and end-of-life environments takes versatility, and Atomicorp agents can enable you to orchestrate detection and response across not only your server and workstation endpoints  but your virtual machines and cloud environments.

With Atomic OSSEC, organizations that still depend on legacy systems get:

    • Out-of-the box integrations with hundreds of systems.
    • More than 400 out-of-the-box connectors to collect log data.
    • A user experience that goes beyond CLI (command line interface) into SIEM consoles, for visual and graphical security event viewing.
    • An ability to run on most operating systems, including Linux and Windows, as well as AIX, Solaris, HP-UX, CentOS, Ubuntu, Linux end of life, Windows EOL, and across major cloud-based software as a service (SaaS) applications. Atomic OSSEC provides  a versatile solution for mixed, modern / legacy system environments.
    • ClamAV and AV management for CVE and vulnerability scanning on all supported platforms, an upgrade from the traditional products available for legacy systems.
    • A boost for firewall and VPN security, further advancing protection over traditional approaches.
    • Support for all major cloud platforms, AWS, Azure, GCP, and more.
    • A security and compliance solution for legacy and end of life systems that addresses NIST 800-53 and 800-171, PCI DSS, GDPR, HIPAA and additional requirements.

Security and Compliance for Linux, AIX, Windows, Solaris, HP-UX, Ubuntu, and More

Atomic OSSEC is the ideal solution for architectures mixing modern and practical legacy systems.
