Security that protects
reputation,
visibility and delivery.
I'm Pranith Jain — a Security Analyst specialized in email deliverability and infrastructure hardening. I protect visibility for 150+ global brands through advanced authentication and threat intelligence.
Managed across Google Workspace & Microsoft Outlook environments.
Active SPF/DKIM/DMARC policy enforcement and monitoring.
Securing the Gateway to Business Operations
I am a Security Analyst with a deep focus on Email Infrastructure and Deliverability. My work bridges the gap between technical security controls and business-critical communication.
With experience managing over 2,000 mailboxes and 1,000 domains, I specialize in architecting resilient outbound systems and enforcing strict authentication policies.

Trusted by Innovators
Securing email infrastructure for 150+ startups and enterprises across AI, HealthTech, and SaaS.
Career timeline
- •Architected and hardened high-availability email infrastructure for 150+ enterprise clients (including FinTech, HealthTech, and AI sectors). Managed security configurations for 2,000+ mailboxes and 1,000+ domains, ensuring resilience against availability attacks and domain blacklisting.
- •Enforced Zero Trust verification standards by configuring Multi-Factor Authentication (MFA) and managing OAuth scopes for secure SaaS integrations across Google Workspace and Microsoft 365. Owned the implementation of SPF, DKIM, DMARC, and BIMI alongside strict MX and TLS policies to protect sender identity and prevent domain spoofing.
- •Engineered automated security workflows using n8n, Webhooks, and APIs to integrate disparate tools. Implemented robust error management and exception handling logic to ensure the integrity of alert pipelines, significantly reducing Mean Time to Detect (MTTD) for reputation incidents.
- •Conducted digital forensics on SMTP/TLS logs and header data using Google Postmaster Tools and MailReach. Proactively detected Indicators of Compromise (IoCs) such as anomalous sending behavior, spoofing attempts, and reputation drift before they escalated into blocking incidents.
- • Developed and maintained the Email Security Playbook, defining Standard Operating Procedures (SOPs) for phishing risk mitigation, domain abuse prevention, and compliant outreach. Enforced campaign-level segmentation to minimize the "blast radius" of potential security or reputation incidents.
- •Resolved 100+ weekly tickets across DNS, email, WordPress and SSL/TLS issues with strong client satisfaction.
- •Specialized in deliverability troubleshooting and security hardening for hosted environments.
- •Built a hospital management system and responsive web UI; worked on API integration and testing workflows.
