About
Cybersecurity engineer · London, Ontario · homelab operator since 2024.
I'm Keval Chhatbar. Cybersecurity engineer, based in London, Ontario.
Day to day, that means detection and response work at a financial services firm — the kind of job where the interesting parts are under NDA and the boring parts are exactly what you'd guess. What you can't guess from a job title is what I do with the rest of my time, which is why this site exists.
I run a homelab that's grown into something closer to a small production environment than a hobby project: a two-node Proxmox cluster, thirty-plus self-hosted services, single-sign-on gating everything that's exposed, and a threat-intelligence pipeline that ships digests every morning whether I'm awake for it or not. I write about it as I build it — the parts that worked, and, more usefully, the parts that broke first. If you want proof I can operate a real system under real failure conditions instead of just describing one in an interview, that's what the writing section is for.
I also spend time on the AI × offensive-security intersection specifically — building agent tooling with actual guardrails (allowlists, audit trails, human confirmation on anything destructive) instead of pointing a model at a shell and hoping. That combination — security engineer who also builds and hardens the AI tooling, rather than treating it as someone else's problem — is what most of this site is actually about.
Current certifications: CISSP, GIAC GCIH, and Microsoft SC-200, among others (thefull list is on the resume page). They're not the point of this site, but they're the credential shorthand for “yes, the operational side is real too,” so I'd rather state them plainly than bury them.
One note on history: I previously published a version of this work pseudonymously, as “MrK,” atkc-explore.github.io. That content lives on and is migrating here — same person, same homelab, real name attached now.
