Sathvik R

I build things to understand them. I break things to protect them.

Security engineer, founder, and builder based in Bengaluru, India.
My work lives at the intersection of offensive security, systems engineering, and shipping real products.
If it has failure modes, attracts attackers, or solves a problem nobody built a tool for yet — I'm building it.


What I've Shipped

CipherSuite — Professional Penetration Testing Workspace

Live → ciphersuite.alcyonesecure.in

The tool I wished existed when doing real security work.
Most pentesters juggle Notion for notes, Google Drive for evidence, and Word for reports.
CipherSuite replaces all of it.

  • Findings manager with CVSS scoring, severity tracking, and status workflow
  • Evidence vault with SHA-256 hashing and bidirectional finding links
  • Split-view markdown notes editor with code block support
  • Tool import parsers for Nmap, Nessus, and Burp Suite XML
  • AI-powered report generation with PDF export
  • Log analyzer with syntax highlighting
  • Just Notes mode — color-coded, self-destruct timers, tags, offline

Alcyone Secure — Cybersecurity Company

alcyonesecure.in

Founded to help Indian SMEs, hospitals, colleges, and hotels comply with the DPDP Act 2023.
Not just paperwork — technical assessments, system audits, and real security controls.

This is how I see how security fails in the real world.


What I'm Working On

  • Building a DPDP Compliance Assessment Platform for employee security awareness testing
  • Completing HackTheBox CPTS certification
  • CompTIA Security+ — exam scheduled
  • New security tooling — details coming soon

Technical Background

How I Think

  • Build first, understand later
  • Break assumptions on purpose
  • Document decisions, not just code
  • If I can build it, I can break it — if I can break it, I can protect it

My degree supports my learning. It does not define it.

These are not side notes.
They shape how I think about conflict, patience, and long-term systems.
