Better Architecture,
simulated end to end.
FlowGround is a hands-on training and simulation platform — built for teams who need to learn how a request actually flows, practice real techniques like JWT verification and request signature checks, and build and pressure-test their own architecture before it reaches production. Every control is something you click, break, and watch get defended — not a paragraph you skim.
Built for learning, simulation, and architecture testing — not documentation
FlowGround isn't a static reference diagram. It's a hands-on platform teams use to train on real techniques, simulate how a request actually moves through a system, and validate an architecture before it goes live.
Security Trainers & Educators
Run live, click-through demonstrations instead of static slides — every attack and its defense animates on its own, on request.
Engineering & Platform Teams
Learn exactly how the controls you already rely on — WAFs, network firewalls, JWTs, signed requests — actually behave under attack.
Architects & Solution Designers
Drag, connect, and reconfigure real AWS, Azure, GCP, and Cloudflare services, then simulate traffic to pressure-test a design before it ships.
Auditors & Security Engineers
Verify a control's behavior directly instead of taking a diagram's word for it — misconfigure it and watch exactly what gets through.
Business Mode & Technical Mode
The same 52 modules, told twice — once for the room full of stakeholders, once for the engineer holding the keyboard.
"Why can't the hacker just log in with a stolen password?"
Business Mode explains 22 topics — signup through payment fraud, multi-tenancy, and AI assistant safety — with zero jargon — a normal flow, an attack, the protection that stops it, and a plain-language result, animated automatically.
- No technical language — built for stakeholders and clients
- Every module auto-plays: watch it before you touch it
- Answers 'what protects us and why does it matter' in under a minute per module
Built like a security training ground, not a wiki page
Every control below is something you click, watch break, and watch get defended — not a paragraph you skim.
Fully Customizable Interactive Architecture
Click through every hop from browser to database — TLS, Cloudflare, AWS Network Firewall, VPC segmentation, load balancing, and more — or rebuild the flow entirely your own way, each with real attack case studies.
Business & Technical Modes
The same controls explained twice: in plain language for stakeholders, and in packets, payloads, and code for engineers.
Animated Attack & Defense Simulations
Watch brute force, credential stuffing, JWT tampering, and SQL injection unfold step by step, then watch the exact control that stops each one.
Burp Suite-Style Request Editor
Intercept, edit, and forward real HTTP requests in a Monaco-powered editor to see exactly how tampering and defenses interact.
Visual JWT Decoder
Edit a token's payload live and watch the signature verification fail in real time — no more mystery around how sessions are protected.
100% Client-Side Simulation
Every scenario runs entirely in your browser from structured JSON — nothing is sent anywhere, so it's safe to explore aggressively.
Start at the top of the stack and follow one request all the way down.
The Architecture Map is the front door — walk through an example flow with real attack case studies, or drop into the fully customizable Playground and build your own.
