About Mani Sai

As a dedicated Cybersecurity Engineer with nearly 4 years of hands-on experience, I specialize in protecting enterprise cloud environments across AWS, Azure, and hybrid infrastructures. My work focuses on designing secure architectures, implementing DevSecOps pipelines, automating threat detection, and leading incident response operations.I’ve successfully:Reduced cloud misconfiguration vulnerabilities by 40% through secure architecture and IAM best practicesDecreased mean time to detect (MTTD) by 35% using automated SIEM workflows in SplunkLowered system exposure by 60% through proactive vulnerability management and CVE remediationStreamlined compliance with NIST 800-207 and Zero Trust Architecture, cutting audit workload by 50%My technical toolkit includes: Terraform, GitHub Actions, Nessus, Burp Suite, PowerShell, Python, and a strong command of IAM, RBAC, and threat intelligence practices.Beyond technical skills, I bring a collaborative and client-focused approach—having delivered security awareness training, built tailored cybersecurity roadmaps, and worked cross-functionally to align security with business goals. Currently pursuing an M.S. in Computer Information Systems at Christian Brothers University Certified in CompTIA Security+| Ongoing learning in ethical hacking & advanced security practicesI’m passionate about continuous improvement, automation, and enabling organizations to stay resilient in a rapidly evolving threat landscape.
