Linux Server Hardening & Security Optimization

Is your Linux server secure and configured for best performance? Our Linux server hardening and security optimization service ensures your systems are protected from cyber threats and misconfigurations. Whether you're running Ubuntu, CentOS, Debian, Red Hat, or SUSE, Jumping Bean provides expert security audits, remediation, and monitoring to keep your systems compliant, hardened, and resilient.

We combine deep Linux engineering expertise with advanced cybersecurity knowledge to assess, secure, and optimize your server infrastructure. From identifying vulnerabilities and misconfigurations to implementing secure settings and monitoring for ongoing threats—we cover the entire stack from OS to application layer.

Comprehensive Linux Security Audit

Our audits evaluate your entire environment, including:

  • OS patch levels and kernel status
  • Open ports, active services, and firewall configuration
  • User and file permission audits
  • Application and middleware security checks
  • Intrusion detection and prevention readiness

You'll receive a detailed report outlining your current exposure, vulnerabilities (CVEs), and misconfigurations, along with remediation steps and recommendations to meet industry best practices and compliance goals.

Server Hardening & Remediation

Based on the audit results, we implement hardening practices that align with standards such as:

  • CIS Benchmarks for Linux distributions
  • DISA STIGs (widely referenced internationally, particularly in high-security environments)
  • ISO 27001 aligned practices and POPIA requirements for local compliance in South Africa
  • Custom policies tailored to your industry or application stack

We disable unused services, configure firewall rules, implement access controls, apply necessary patches, and enforce secure system defaults. Our goal is to reduce your attack surface and improve operational resilience.

Linux Server Security Monitoring

Security isn’t a one-time event. As part of our managed Linux services or integrated into your existing security operations, we offer ongoing monitoring of your system’s performance and security. This includes log analysis, alerting, and anomaly detection using open-source SIEMs and tools like OSSEC, Wazuh, and Prometheus.

Get Peace of Mind

If you're unsure whether your systems are truly secure, or you need to meet regulatory or compliance obligations like PCI-DSS, POPIA, or ISO 27001, we can help.
