Fidelis Server Secure - 2026 Pricing, Features, Reviews & Alternatives

Fidelis Server Secure is a cloud workload protection platform that automates security and compliance management for Linux and Windows servers across public, private and hybrid cloud environments. The service is part of the Fidelis CloudPassage Halo ecosystem and employs patented microagent technology to provide comprehensive workload protection with minimal resource consumption. It addresses evolving security challenges in dynamic cloud infrastructures where the majority of business workloads reside in data centers hosted by cloud providers. The solution supports enterprise environments in sectors such as defense, government, healthcare, finance, information technology, education, retail and tribal gaming by delivering continuous visibility, runtime threat detection and compliance monitoring across distributed server assets.

The platform delivers a combination of configuration security monitoring, file integrity monitoring, intrusion detection and network traffic analysis controls. Configuration monitoring inspects system files, running processes, permissions and settings to identify unauthorized changes by leveraging preconfigured policies for operating systems and cloud services including databases, web servers, container platforms and orchestration frameworks. File integrity monitoring detects unauthorized modifications to system binaries, configuration files and registry keys and alerts on anomalies arising from benign changes or malicious activity. Log based intrusion detection captures and correlates security events from operating systems and applications to detect behaviors such as suspicious login attempts, privilege escalations, unauthorized account additions, policy adjustments and software installation or removal. Network traffic analysis gathers details on inbound and outbound connections and applies automated firewall policies to block or allow traffic based on observed patterns while providing a visual topology to aid in anomaly detection. Vulnerability management continuously assesses workloads for security exposures and prioritizes remediation efforts. Local account monitoring uncovers insecure configurations, dormant accounts and misassigned permissions to reduce the risk of insider threats.

The patented microagent uses only two megabytes of memory and consumes negligible disk space while operating without additional software or Java runtimes. It persists through operating system patches without requiring reinstallation and completes registration on infrastructure as a service platforms, virtual machines, physical servers and bare metal hosts in thirty seconds. Full inventory, evaluation and instrumentation for ongoing monitoring are achieved within ninety seconds. The microagent communicates unidirectionally to the Fidelis Halo cloud to reduce tampering risks and performs hourly assessments to detect signs of compromise. Monitoring intervals can be customized per server or asset group and ad hoc scans can be initiated to obtain immediate insights into intrusion detection data, file integrity status, anomalous network traffic and configuration drift.

An API-first architecture exposes all Server Secure capabilities through a comprehensive REST API and software development kit, enabling integration into DevSecOps pipelines and continuous integration workflows. Deployment scripts support Chef, Puppet, Bash and other common automation tools while microagents can be preconfigured into server images for seamless provisioning. A plugin for Jenkins supports native pipeline integration and a dedicated SDK facilitates advanced orchestration across continuous deployment platforms. All remediation data and policy configurations are available in JavaScript Object Notation for automation with security information and event management, security orchestration, automation and response and governance, risk and compliance tools. The service maintains tamper-proof records of technical and operational compliance for all workloads and consolidates security and compliance data from initial agent registration through ongoing remediation. The solution is compatible with a range of Linux distributions and Windows Server versions and supports deployment across cloud providers, private clouds and on-premise infrastructure with microagent delivery as host-based software or containerized runtime.
