Hi, I'm Lalan Prasad

“Bridging the gap between technical depth and business value in cybersecurity.”

Principal Sales Engineer at Cohesity with 20+ years of experience helping enterprises secure their data with AI-driven solutions across hybrid and multi-cloud environments.

About Me

With over 20 years of experience in cybersecurity, I bring a deep understanding of enterprise security from both technical and strategic perspectives.

Having worked at industry leaders like Cisco, Juniper, SentinelOne, and Zscaler, I've led pre-sales engagements, built technical demos, and partnered with customers across public sector, BFSI, and enterprise verticals to architect security solutions covering ZTNA, XDR, ITDR, and DLP.

I've also worked with high-growth cybersecurity startups — ColorTokens (Micro Segmentation) and Attivo Networks (Deception-based Security & Identity Security) — gaining hands-on experience in shaping innovative security narratives and driving adoption of next-gen technologies.

Currently at Cohesity, I focus on helping enterprises leverage AI-driven data security to protect, recover, and govern their most critical assets across hybrid and multi-cloud environments.
