BRIAN
DEITCH

I explain the future of security before the market catches up.

Two decades in the trenches. Zero Trust before it was a buzzword. Cloud when everyone said it wouldn't scale. Still here.

THE LIGHTBOARD
IS THE WEAPON

Brian doesn't just explain security. He draws the architecture, exposes the assumptions, and makes complex ideas click — live, on glass, in real time.

02 / The Topics

WHAT BRIAN
TALKS ABOUT

Hover each topic for Brian's unfiltered take.

01
Zero Trust Architecture
“The framework that actually maps to how attackers move. Everything else is perimeter theater.”
02
SSE / SASE
“The architecture the industry finally agreed on. Now let's talk about who's actually doing it right.”
03
SSL/TLS Inspection
“Encrypted traffic is where threats live now. If you're not inspecting it, you're flying blind.”
04
Cloud Security
“Moving to the cloud doesn't make you secure. It gives you new attack surfaces and old assumptions.”
05
Agentic AI Governance
“Agents that act on your behalf need the same Zero Trust treatment you give humans. Actually, more.”
06
DDoS / DoS Mitigation
“A 3 Gbps attack can drop a 40 Gbps firewall. The math matters more than the marketing.”
07
Identity & Access
“Identity is the new perimeter. Treat it like the perimeter you actually care about.”
08
Threat Intelligence
“Knowing what's out there is table stakes. Acting on it before it acts on you is the game.”
09
Zero Trust Platform Architecture
“It's not a product. It's the only architecture that actually works at scale.”
10
Zero Trust Branch
“MPLS is not a security strategy. Neither is a firewall at every site.”
11
Zero Trust Cloud
“Cloud security is not lifting your data center problems into someone else's building.”
12
Zero Trust Browser
“The browser became the new endpoint while everyone was still arguing about agents.”
13
True East/West Microsegmentation
“Stop pretending the inside is safe. That movie ended badly.”
14
AI Asset Discovery & Governance
“Not vibes. Visibility, control, and proof.”
15
Secure Access to AI Apps
“Your users are already using it. The question is whether you know about it.”
16
AI Data Security / DSPM
“The whole game is knowing where the data is, where it moves, and who touches it.”
17
Agentic AI Control
“Agents making API calls at machine speed. Without Zero Trust, that's the breach.”
18
MCP / API / Toolchain Security
“The attack surface just grew by every tool your LLM can reach.”
19
AI Attack Surface Management
“You can't protect what you can't see. And right now, you can't see most of it.”
20
AI-Driven SecOps
“Finally using AI to fight AI. About time.”

SECURITY IS NOT
A CHECKBOX

I've been in enterprise security long enough to watch the industry invent problems, then sell the solution. I call that out.

At Zscaler, I help organizations understand Zero Trust not as a product, but as an architecture. The conversation starts with honest assessments, not vendor decks.
