Solaris Security

Protect legacy and end-of-life Solaris OS environments and facilitate compliance

The Oracle Solaris operating system, while no longer widely deployed, remains a critical platform in many enterprise and legacy IT and OT environments. Organizations continue to rely on Solaris for its stability and long-term application support in mission-critical workloads across utilities, energy, telecom, finance, and manufacturing.

Solaris EOL Security and Compliance

However, limited IT and OT visibility makes effective security and compliance difficult to maintain. Legacy and end-of-life Solaris systems often lack modern security controls such as antivirus, file integrity monitoring, and regular patching, allowing vulnerabilities to accumulate and increasing exposure to regulatory risk and cyberattacks.

Overcome the security and compliance challenges of your legacy Solaris environment with Atomicorp endpoint detection and response (EDR) solutions. Atomicorp offers deep integration with specialized IT hardware or OT systems where most modern security stacks are not compatible.

Solaris Security FAQ

Where can I get advanced protection for legacy and EOL Solaris?

When official OS vendor patches stop, you can protect the system using third-party endpoint security, intrusion detection, and monitoring tools that still support Solaris, including EOL versions. An advanced and affordable option is the Atomic OSSEC EDR solution, which monitors and protects Solaris 11 and other legacy Unix platforms. Atomic OSSEC provides:

  • Log-based IDS and SIEM to aggregate and analyze Solaris event data and telemetry
  • Real-time file integrity monitoring (FIM) and FIM as a system of record for auditing and compliance
  • Anti-malware and memory-resident malware detection with automated response options and orchestration remediation
  • Active response through automated response rules
  • Compliance scanning, benchmarking and response rules and tools to make legacy Solaris OS server compliance possible across NIST, PCI DSS, and many other standards

How Does Atomicorp Address Security’s Impact on Solaris Performance Disruption?

When other cybersecurity vendor tools won’t interoperate with Solaris OS or are a resource hog or too expensive, Atomicorp solutions provide an affordable and noninvasive alternative.

Minimizes Endpoint Resource Consumption Through Centralized Analysis

Atomic OSSEC can be deployed either as a centrally managed platform with lightweight endpoint agents for granular host-level protection, or as an agentless monitoring and detection solution. In both models, resource-intensive processing—such as correlation, behavioral analysis, and long-term data analysis—is handled by the Atomicorp management hub rather than the endpoint itself. This architecture reduces endpoint memory and CPU utilization while maintaining continuous visibility and control, with the hub deployable on-premises or in the cloud.

Works Without Cloud Dependencies

Cloud platforms such as AWS and GCP are foundational infrastructure for many businesses and organizations. When the cloud goes down, it impacts not only dependent services but basic protections as well. Atomicorp provides endpoint based intrusion prevention that keeps your devices and data secure, even during a widespread cloud or internet outage. It requires no internet or cloud connection to prevent, detect, and respond to keep your services protected and available. The Atomic OSSEC agents persist across reboot and patching automatically to keep Solaris IT and supervisory OT platforms running smoothly and securely.


Solaris Security and Compliance Support for Mission-Critical, Legacy Environments

Atomicorp, an EDR software provider, offers endpoint and cloud workload protection for enterprises seeking to overcome legacy Solaris visibility gaps, security vulnerabilities, and compliance and risk factors.

While many cybersecurity vendors have moved off support for Solaris OS, Atomicorp continues to offer and develop new security and compliance features for the platform.

We provide:

  • Advanced and lightweight endpoint security management software for Solaris environments, back to Solaris 11, with no production impact.
  • Intrusion prevention through endpoint antivirus (AV), Solaris-specific signatures, and firewall capabilities for Solaris OS.
  • Host based or agentless Solaris endpoint monitoring that includes malware memory detection.
  • Log based intrusion detection and machine learning analysis that automates response and sends alerts and details to the SIEM interface for further response actions.
  • Secure access control through least privilege design, integrated MFA, root escalation detection, and native Solaris system hardening and Solaris OS-level protection.
  • Defense-in-depth protection and automated response rules that identify, block and isolate threats and mitigate risk and damages. The EDR’s functions cover all five security pillars of prevention, monitoring, detection, response, recovery, and more.
  • Continuous monitoring and real-time file integrity monitoring and alerting to reduce Solaris visibility gaps and more rapidly identify root causes, resolve, and reduce mean time to repair (MTTR).
  • SIEM and GUI. Atomic OSSEC provides a SIEM presentation layer for asset and endpoint agent management, central security service orchestration. The Atomic OSSEC SIEM can also integrate with custom or third-party SIEM and network monitoring tools.
  • Affordable EDR and compliance readiness for legacy Solaris servers and virtual endpoints. Atomic OSSEC supports PCI DSS, NIST 800‑53/171, ISO/IEC 27001, HIPAA, GDPR, 10 CFR 73.54, and OT security standards like IEC 62443. It delivers antivirus, tamper and intrusion detection and prevention, continuous monitoring, access control, configuration management, vulnerability protection, automated response, audit controls, and regional storage controls to help meet software compliance requirements on Solaris platforms.

Affordable Security and Compliance Solutions for Solaris Systems

Atomic OSSEC provides cost-effective host-based detection, response, and compliance monitoring for Oracle Solaris environments. While most endpoint and cloud EDR solutions cost $8–$20 per device per month, Atomic OSSEC delivers deeper, Solaris-specific visibility at a lower total cost of only $5 per device per month. Support includes daily rule updates, thousands of security and compliance controls, automated active response, and expert Solaris support.

 

Why choose Atomicorp for advanced Solaris 11 security?

Security and compliance are vital as Solaris systems continue to power critical operations. Atomicorp provides affordable, compatible, and advanced protection designed for Solaris environments. Its flexible security platform helps legacy and long-running Solaris deployments maintain performance while meeting modern compliance requirements.

Atomic OSSEC EDR Software

We recommend this for Solaris user organizations seeking deep, real-time endpoint detection and runtime workload scanning. The agents continuously monitor and protect the device, OS, virtual machines, files, and data, and a SIEM with GUI enables you to orchestrate services, with help from Atomic professional support. Stay secure and agile with the security analysis removed from the endpoint for powerful and granular lightweight on-device protection.

Atomic OSSEC Software as a Service (SaaS)

Atomic OSSEC also comes in an agentless EDR and compliance SaaS offering for highly sensitive production environments that can’t be monitored directly on the devices.
