Sahil Sharma

I’m a Senior Cybersecurity Engineer specializing in PKI & SIEM. With 7+ years of enterprise experience, I architect and automate Venafi CLM X.509 certificate lifecycle management, alongside SIEM operations and endpoint security ecosystems.

I’ve delivered measurable impact by reducing certificate operational overhead by 60%+ using PowerShell automation and Venafi vedSDK API-driven workflows. I also reduced certificate-related incidents by 40% through proactive monitoring and automated renewal.

My work spans hybrid cloud PKI with AWS Private CA, AWS KMS, and CloudHSM, plus Microsoft ADCS CA hierarchy and infrastructure support (CA servers, CDP, IIS). On the SIEM side, I manage Exabeam DataLake operations—parser configurations, log ingestion architecture, and correlation rule development for threat detection.

I ensure reliability in day-to-day security operations, coordinating vendor escalations and maintaining 99.9% SIEM uptime. I also strengthen endpoint coverage through CrowdStrike Falcon and SentinelOne administration, and I’ve built a centralized PKI web portal (HTML/CSS/JS) for real-time certificate visibility and monitoring.
