Back to original languageAbout Issam
Cybersecurity engineer specializing in SIEM and security solutions integration. I assist companies in the administration, optimization, and operation of their monitoring and cybersecurity tools.
With experience in large accounts and demanding clients, I work on high-value technical subjects: log collection and onboarding, data normalization, parsing, dashboard creation, advanced technical support, troubleshooting, and continuous improvement of security platforms.
I have particular expertise in Splunk: administration, distributed architecture (UF, HF, Deployment Server), data ingestion, SPL queries, dashboards, technical incident diagnostics, and performance optimization. I have also worked on vulnerability management with Rapid7 InsightVM, as well as the integration and deployment of cybersecurity solutions.
I am comfortable working in Windows/Linux environments and appreciate contexts requiring autonomy, rigor, and analytical skills. My goal is to provide concrete, reliable, and pragmatic solutions to IT and security teams.
Types of missions sought:
• Splunk administration/expertise
• SIEM integration/log source onboarding
• Cybersecurity L2/L3 support
• Vulnerability management
• Security solution deployment
• Security tool monitoring and improvement
An involved, adaptable, and results-oriented professional, I can intervene in both technical aspects and in exchanges with clients, partners, and internal teams.
