About

Small crew, loud clarity

Cipher Lantern Labs exists because Japanese security teams asked for offensive practice that still reads as professional on Monday. We bias toward scenario-driven labs, ethics-first guardrails, and documentation templates procurement teams can follow.

Principles we defend in every cohort

Scope before spectacle — no ad-hoc scanning outside signed ranges.
Evidence discipline — screenshots tied to activity log lines, not vibes.
Mentor proximity — small groups so feedback stays specific, not generic.
Honest limitations — we say no when a scenario needs a bespoke bootcamp instead.

Milestones

2019

Pilot cohort in Shibuya

First closed lab with two enterprise clients testing cross-org workflow reporting templates.

2022

Hybrid delivery launch

Introduced synchronized remote rooms with mirrored lab VLANs for distributed teams across Kansai and Tokyo.

2025

Readiness assessments

Added structured interviews plus safe technical probes that feed a prioritized learning backlog without production touch.

Team

Lead Ethical Hacking Instructor

Mika Sato

Designs scenario arcs that mirror Japanese enterprise client environments while keeping every pivot inside signed lab scopes.

Curriculum Designer

Jonah Reeves

Builds narrative ladders from passive discovery to written briefs so cohorts never drown in tool output without meaning.

Lab Environment Engineer

Kenji Mori

Maintains snapshot cadence, VPN profiles, and classroom kill switches so a single mistyped command cannot wander out of VLAN bounds.

Security Research Analyst

Elena Varga

Tracks cloud control plane changes and feeds short briefings to mentors before each cohort so examples stay current.

Client Success Coordinator

Amelia Chen

Coordinates roster logistics, dietary notes for in-person weeks, and post-workshop survey synthesis for returning teams.

Train Like an Attacker, Report Like a Professional

Upcoming workshops

We publish open cohorts quarterly. Teams can also request private runs that reuse the same lab spine with swapped narratives. Check the catalog for the latest JPY amounts and durations—numbers shift when we add new modules.

Practice lab experience

VLAN isolation, mentor kill switches, and nightly disk resets keep exercises inside the room. Participants rotate attacker, scribe, and operator seats so everyone practices stakeholder sign-off language—not just shell access.

Corporate training options

Private bootcamps inherit the same safety interlocks but swap in your architecture diagrams under NDA. We pair a lead instructor with a client success coordinator so logistics never land on your engineers unexpectedly.

Volume benefits appear once you commit to three cohorts within a fiscal year—ask for the spend tier worksheet during pricing conversations.
