Make security work in the real world.
Security architecture is only useful when teams can operate it and systems can live with it.
I’m George Kuznyetsov. I help organizations examine complex security challenges across infrastructure, cloud identity and connected environments — and publish practical lessons engineers can apply.

01 / SERVICES
Where I can help.
Focused reviews and advisory work, not a vague promise to solve every security problem. Start with the architecture, evidence and business constraints you already have.
02 / IDENTITY
Identity security assessment
AD and Entra identity security, access lifecycle, MFA strategy and control validation.
Review this service03 / SPECIALIST
IT / OT security advisory
Architecture-level guidance for connected building and distributed operational environments.
Review this service02 / TWO WAYS IN
Built to be useful.
The technical work is public when it can safely be shared. The commercial work starts with a conversation.
FOR ENGINEERS & PEERS
Take something you can use.
Checklists, validation workflows, architecture notes and security labs. Less buzzword recycling, more assumptions, test cases and limitations.
Explore the guidesFOR LEADERS & TEAMS
Make a difficult decision clearer.
Need an independent set of eyes on identity, infrastructure or a security design? Begin with an explicit scope and a useful deliverable.
Discuss an engagement03 / FIELDWORK
Real problems. Useful lessons.
Examples from professional experience are presented at a safe level of abstraction, without client-owned diagrams, credentials or confidential implementation detail.

Show your evidence.
Useful security work can be reproduced, challenged and improved. Start with one complete, openly available technical guide.
GUIDE 001 / SOC + AI
Evidence before verdict
A practical checklist for validating security investigation claims when AI and automation are involved. Includes negative tests and a sample evidence contract.
Read the practical guideHOW I WORK
Architecture. Constraints. Accountability.
Understand the system, define the trust boundaries, identify what can actually be tested, and be explicit about what remains uncertain.
