Your Computer Was
Abandoned. We Fixed That.

Microsoft cut off 800 million Windows computers. No more patches. No more protection. Pulsar Sentinel wraps every machine in quantum-proof encryption, logs every event to the blockchain, and passes your digital life to your family when you're gone — automatically, on-chain, no lawyers.

The World Has a Security Crisis

Three converging threats are about to leave billions of people exposed. Nobody is talking about it.

Abandoned by Microsoft

Windows 10 end-of-support means no more security patches. Every hacker on earth knows these machines are defenseless.

800M

Quantum Computing is Coming

When quantum computers arrive, every password, every bank account, every encrypted file on the planet becomes readable. Today's encryption dies overnight.

2030

Your Digital Life Dies With You

When you die, your photos, passwords, crypto, and digital assets vanish. No inheritance plan exists for your digital life. It's just... gone.

100%

One Install. Total Protection.

Pulsar Sentinel solves all three problems with a single security layer.

Quantum-Proof Encryption

ML-KEM lattice-based encryption that quantum computers can't crack. Combined with AES-256 for defense-in-depth. NIST-approved. Military-grade. Runs on your old laptop.

Blockchain Audit Trail

Every security event is cryptographically signed, batched into a Merkle tree, and permanently recorded on the Polygon blockchain. Tamper-proof. Permanent. Legally defensible.

Automatic Inheritance

Designate your heir. If you're unresponsive for 90 days, your digital assets transfer automatically via smart contract. No lawyers. No probate. No lost memories.

Up and Running in Three Steps

01

Create Account

Go to sentinel.shanebrain.cloud. Connect your MetaMask wallet. That's your identity — no passwords to steal, no account to hack.

02

Choose Your Tier

Pick Legacy Builder, Sentinel Core, or Autonomous Guild. Stripe handles billing. PQC encryption activates immediately on your account.

03

You're Protected

Every API call is quantum-encrypted. Every event logged to the blockchain. Threat score live. Digital inheritance armed. Nothing Microsoft does affects you anymore.

This is Digital Sovereignty

You don't rent security from Microsoft. You don't trust Google with your keys. You don't depend on any corporation that can decide you're not worth protecting anymore.

  • Your keys, your machine. Encryption happens locally. Keys never leave your device.
  • Your rules, enforced by code. Self-governance rules run autonomously. No human middleman.
  • Works offline. If the internet goes down, your machine is still protected. Local-first architecture.
  • No corporate kill switch. Nobody can revoke your security. It's math, not a subscription to someone's cloud.

Self-Sovereign Identity

Your wallet is your identity. No corporation issued it. No corporation can revoke it.

Self-Governance

RC codes enforce rules automatically. Three strikes? Banned on-chain. No appeals department needed.

Real-Time Threat Score

Every device gets a live PTS threat score. Green, yellow, red. You see everything happening on your network.

Network-Wide Protection

One install protects one machine. Scale it to every device on your network from a single dashboard.

Heir Transfer Protocol

  • Day 1 - You activate Pulsar Sentinel Every file encrypted. Every action logged on-chain. Your digital estate begins.
  • Years pass - Your legacy grows Photos, documents, crypto, passwords - all quantum-encrypted with an immutable chain of custody.
  • Day 90 of inactivity - Smart contract activates RC 1.02 triggers automatically. Your designated heir receives access to your entire digital life.
  • Forever - Blockchain proves ownership Every transaction hash is permanent proof. Your grandchildren can verify the chain of custody 50 years from now.

A Digital Trust Fund for Your Family

Right now, when you die, your digital life vanishes. Your photos. Your passwords. Your crypto. Your memories. Gone.

Pulsar Sentinel changes that. Every digital asset you own is encrypted, audited on the blockchain, and automatically inheritable. The blockchain IS your estate plan.

Your digital life doesn't die with you. It transfers to your family. Automatically. On-chain. No lawyers.

Choose Your Protection

From a single laptop to an entire network. Security that scales with you.

Built With Purpose

Why This Exists

My name is Shane Brazelton. I'm a concrete dispatcher in Hazel Green, Alabama. I have five sons, a wife recovering from brain surgery, and no computer science degree. I built this because I saw something nobody with the resources to fix it was bothering to fix.

800 million people just got abandoned by Microsoft. Not tech people. Regular people. Grandmothers with photos of their grandchildren. Small businesses running payroll. Families whose entire digital lives live on machines that will never see another security patch. Hackers already know these machines exist. They're already coming.

I started building ShaneBrain on a Raspberry Pi in my house because I believe local AI and real security shouldn't cost enterprise prices and shouldn't require a computer science degree. I built Pulsar Sentinel on the same Pi. It runs right now. It's real. You're looking at it.

"I named Angel Cloud after my daughter-in-law Angel. Every project I build serves the family — my family, and the 800 million families that got left behind. This isn't a startup. It's infrastructure. Build it once. Secure it forever."

I'm two years sober. I code every night after my family goes to sleep. This project — everything in the Angel Cloud ecosystem — is the work. Faith. Family. Code. That's the whole thing.

800 million users. Digital legacy for generations. Built in Alabama on a Raspberry Pi. That's the mission.

Your Computer Was Abandoned.
You Don't Have to Be.
