Open source security implementation and consultancy

Leveraging open source security is a strategic advantage for businesses, offering cost-effective, high-quality solutions that drive innovation. It provides access to cutting-edge technology without the burden of escalating licensing fees, enabling seamless deployment, customisation, and flexibility. This approach allows businesses to audit and adjust their security measures in real time, ensuring they remain resilient against emerging threats in a fast-evolving cyber landscape.

Metasure offers expert consultancy and implementation services for OSSEC and Wazuh, scalable open-source intrusion detection systems. Our services include log-based intrusion detection, real-time file integrity monitoring, rootkit and malware detection, compliance auditing, system inventory management, and active response.

By integrating OSSEC/Wazuh with SIEM systems, we reduce data volume and SOC personnel noise ultimately lowering SIEM costs.

We provide full architecture design, development, implementation, integration, migration, ongoing management, and machine learning-based threat intelligence for in an easily deployable hosted, hybrid or premise solution.

Metasure provides Open Source Security Consultancy & Implementation Services across

Log-based intrusion detection

Actively monitors and analyses data from multiple log data points in real time.

Compliance auditing

Application and system level auditing ensures compliance with many common standards, such as PCI-DSS and CIS benchmarks.

System inventory

Collects system information, such as installed software, hardware, utilisation, network services, and listeners.

Rootkit and malware detection

Process and file level analysis detects malicious applications and rootkits.

File integrity monitoring

For both files and Windows registry settings in real time, detects changes to the system, and maintains a forensic copy of the data as it changes over time.

Active response

Responds to attacks and changes on the system in real time through multiple mechanisms, including firewall policies, integration with third parties such as content delivery networks and support portals, as well as self-healing actions.

Many organisations choose to integrate OSSEC/Wazuh with a security information and event management (SIEM) system to report events to their security operations center (SOC). In this case, OSSEC plays the role of a log aggregator and only sends actionable information to the SIEM.

This reduces data volume in the SIEM, which cuts down on noise for SOC personnel and often results in dramatic reductions in SIEM costs.
