From SIEM and EDR to CSPM, XDR, and Threat Intelligence, these solutions offer enterprise-grade protection without the high cost of proprietary software. At Ucyfer, we specialize in identifying, integrating, and managing the best open source tools to safeguard your endpoints, networks, cloud workloads, and data. Our expert team ensures these technologies work in harmony—offering you seamless, scalable, and secure defense tailored to your unique environment.

Key Domains Covered by Open Source Cybersecurity

1. Vulnerability Management Systems (VMS)

Tools like OpenVAS and Wazuh help organizations detect, classify, and prioritize vulnerabilities across endpoints and servers. We ensure you have automated scanning and contextual risk analysis embedded in your CI/CD pipeline and IT operations.


2. Endpoint Detection and Response (EDR)

Osquery and Velociraptor deliver deep endpoint visibility and real-time detection of anomalous behaviors. Our integration services empower your SOC team with actionable insights and forensic capabilities.


3. Security Information and Event Management (SIEM)

Elasticsearch, Logstash, and Kibana (ELK Stack) paired with Wazuh can form a powerful SIEM solution. We tune and correlate logs to create a centralized threat-monitoring hub tailored to your environment.


4. Data Loss Prevention (DLP)

OpenDLP and MyDLP offer scanning and monitoring of sensitive data. We align these tools with your compliance requirements to prevent accidental or malicious data exfiltration.


5. Database Activity Monitoring (DAM)

Tools like OSSEC and pgAudit can monitor and log database activities. We deploy and fine-tune these solutions to detect unauthorized data access in real time.


6. Extended Detection and Response (XDR)

Combining EDR, SIEM, and threat intelligence through open source orchestration platforms like TheHive and MISP delivers XDR-level visibility. Our team orchestrates and operationalizes this stack for 360° threat coverage.


7. Threat Hunting

Using platforms like Sigma, HELK, and MITRE ATT&CK frameworks, we enable proactive threat hunting across your infrastructure. Our analysts help you move from reactive to predictive security.


8. Cyber Threat Intelligence (CTI)

MISP and OpenCTI allow you to collect, enrich, and share threat intelligence. We connect your environment to trusted sources and tailor the feeds to your threat landscape.


9. Incident Response

IR platforms like TheHive and Cortex provide case management, automation, and evidence tracking. We configure playbooks and response workflows to accelerate your incident resolution process.


10. Cloud Security Posture Management (CSPM)

Tools such as Cloud Custodian and Prowler ensure your cloud configurations meet security best practices. We embed these into your CI/CD to maintain compliance and visibility across multi-cloud environments.


11. Cloud Workload Protection (CWP)

Falco and kube-bench offer runtime protection for containerized workloads. Our experts configure these tools to monitor, alert, and prevent exploitation within Kubernetes and Docker environments.
