About

Hi, I’m Nishanth.

I’m a security automation engineer with 10+ years in security operations, passionate about taking repetitive work off people so they can focus on what matters.

Today I help leading companies run their security operations on a single platform and adopt AI safely, turning manual response into automation that scales. I don’t just deploy tools; I design the automation and architecture that make them work.

Outside work I keep building: this website, Celeste, my AI assistant, and my own private dashboard.

My story

From pulling apart malware to the unified SOC.

  1. Pulling malware apart

    I started out researching malware: taking suspicious files apart, deciding what was malicious and writing the signatures that stopped it.

  2. SOC, hunting & response

    Then I moved into the SOC: monitoring, threat hunting and incident response, automating the repetitive parts as I went.

  3. Automation at scale

    Automation became my craft. I led SOAR programmes, designed playbook frameworks and built the teams and training that made them stick.

  4. The unified SOCNow

    My work now spans the whole SOC platform, from SIEM, XDR and cloud detection to automation, exposure management and threat intelligence, plus securing AI agents.

How I help

I help leading companies see threats sooner and respond faster.

Unified security operations

Bringing SIEM, XDR, cloud, identity, attack surface and threat intelligence together, so teams see the whole attack and act on it fast.

Threat hunting and response

Detection rules, threat hunts and incident response that catch real attacks and cut the noise.

Automation that scales

SOAR playbooks, integrations and enablement that take repetitive work off analysts and keep response consistent.

AI and agent security

Helping teams adopt AI safely, from AI apps to the agents, extensions and tools on every endpoint.

Side projects

Things I build in my own time.
