Jeremiah Rod Jacinto

Cybersecurity Specialist with over 3 years of experience spanning both Managed Service Provider (MSP) and in-house environments, offering a versatile background in managing diverse client infrastructures and dedicated internal security operations. Currently serving as an IT Cybersecurity Officer at ACOM Consumer Finance Corporation, I leverage strong communication skills to bridge the gap between technical defense and internal management, ensuring security initiatives align with business objectives. I have successfully managed and led the end-to-end project implementation of critical security stacks, including CrowdStrike SIEM/XDR, Microsoft Purview (DLP), Microsoft Intune (MDM), and Microsoft Defender for Office 365.

Beyond deployment, I specialize in consolidating endpoint, identity, and email telemetry into unified dashboards to enhance threat visibility. My expertise lies in fine-tuning detection parameters, optimizing anti-phishing and data protection policies, and enforcing robust device compliance to significantly reduce organizational risk and improve incident response efficiency.
