Why Atomic OSSEC
Atomic OSSEC is an endpoint detection and response (EDR) and cloud workload protection system. The Atomic OSSEC EDR provides intrusion prevention, endpoint AV and firewall, FIM, and server, and workstation and cloud API protection at a lower TCO than most comparative commercial offerings.
Atomic OSSEC for EDR and Compliance
Atomic OSSEC provides security and compliance capabilities for server, desktop, cloud, container, and Web API environments. It includes:
Intrusion Detection
Detect anomalous behaviors on servers and cloud workloads.
File Integrity Monitoring
Validates integrity of operating systems and application files.
Log Management
Manage log events and route to SIEMs or other monitoring systems.
Active Response
Trigger alerts or other actions based on changes to systems or files.
CVE Scanning
Detect CVE and other vulnerabilities across modern and legacy Windows, AIX, Linux, Solaris, and Unix-based systems.
Compliance
Whether it’s PCI DSS, NIST 800-53, NIST 800-171, NIST 800-82, FIPS, GDPR, HIPAA, or other requirements, compliance demands ongoing effort for which your security and compliance personnel need help.

Atomic OSSEC FAQs
Is Atomic OSSEC an EDR?
Yes. Atomic OSSEC is an endpoint detection and response (EDR) platform designed to protect servers, endpoints, and cloud workloads. Unlike other vendors that narrowly define EDR, Atomic OSSEC delivers robust, real-time monitoring and response capabilities across diverse environments—without requiring expensive add-ons or restrictive licensing. Learn more.
How does Atomic OSSEC compare to CrowdStrike and other big-name EDR solutions?
Atomic OSSEC is more cost-effective, open, and platform-agnostic. With many commercial EDR vendors, you risk vendor lock-in—buy one product and you’re pushed into the whole suite. Atomic OSSEC integrates flexibly with existing tools, supports a broader range of platforms and cloud environments, provides transparent, customizable security, and can run in air-gapped environments. Details here.
Does Atomic OSSEC support end-of-life (EOL) operating systems?
Yes. Many organizations rely on older or unsupported systems. Atomic OSSEC provides coverage for end-of-life platforms that other EDR vendors ignore, helping you maintain security while you transition or maintain critical legacy infrastructure. See supported legacy platforms.
Can Atomic OSSEC run in air-gapped or government/intel environments?
Absolutely. Atomic OSSEC was built for sensitive use cases where cloud-based monitoring is not possible. It can operate fully air-gapped, making it a strong choice for government, military, and intelligence organizations. Learn more.
How does Atomic OSSEC work for operational technology (OT) and industrial systems?
Many plant equipment and control systems are too sensitive or old to support direct installation of security software. Atomic OSSEC can monitor OT environments without agents, so you don’t need to modify machinery or install software on critical systems. This simplifies meeting security and compliance requirements in air-gapped or regulated environments while keeping operations stable. Learn more.
Can Atomic OSSEC EDR work in cloud environments?
Yes. Atomic OSSEC protects cloud workloads and cloud APIs with real-time file integrity monitoring to detect file, system, and configuration changes, traces of malware, and to support forensics. It also provides SIEM for visibility, reporting, and compliance—plus microsegmentation to contain threats and cross-tenant contamination. Platform overview.
How does Atomic OSSEC help with compliance?
Atomic OSSEC includes compliance and auditing capabilities out of the box. This makes it easier to meet standards such as PCI DSS, HIPAA, SOX, NIST, and other government frameworks without costly third-party tools. Compliance details.
Does Atomic OSSEC include antivirus?
Yes. Atomic OSSEC includes server-grade antivirus and additional intrusion prevention, detection, and response not found in antivirus products or point solutions. Antivirus & anti-malware.
How is Atomic OSSEC different from just applying patches?
Patching is essential, but it can’t address every risk. New exploits emerge daily, some vulnerabilities remain unpatched or unpatchable, and compromised updates can introduce more risk. Atomic OSSEC adds continuous monitoring, proactive threat detection, and real-time protection—safeguarding systems even when patching isn’t an option. Learn more.
Does Atomic OSSEC impact system performance?
No. Atomic OSSEC is lightweight and optimized to minimize system load. Unlike some EDR solutions with heavy scanning overhead, it’s designed for load-sensitive environments and won’t significantly impact performance. Performance overview.
How responsive is Atomicorp’s support for Atomic OSSEC?
We use a ticket system for tracking and accountability, but unlike large vendors, tickets don’t disappear into a queue. When you open a case, you get quick responses from a small team of experts who learn your environment and your team. Customers frequently cite our responsiveness and personal approach as a key advantage. Contact support.
How does Atomic OSSEC fit into modern Zero Trust security models?
Zero Trust means no asset inherently trusts another. Atomic OSSEC aligns with this model by enabling endpoints, servers, and workloads to defend themselves independently—even without network-based controls. Zero Trust with Atomic OSSEC.
Can Atomic OSSEC integrate with my existing security stack?
Yes. Atomic OSSEC is open and extensible. It integrates with SIEMs, AV tools, and other security technologies, so you can expand coverage without discarding existing investments. Integration overview.
