A New Way to Stay Connected

4C Pulse is being built as a modern real-time messaging platform with secure transport, authenticated sessions, protected device credentials, controlled storage, and a scalable service architecture.

Security by Design

The platform is being engineered around established mobile and application-security practices. The current implementation focuses on the controls already deployed, while advanced end-to-end encryption and key management remain part of the security roadmap.

🔐
TRANSPORT

HTTPS + Secure WebSockets

Encrypted HTTPS and WSS channels protect application traffic between the Android client and the production edge.

🛡️
AUTHENTICATION

Authenticated Sessions

JWT-based authentication is used for protected API and WebSocket access, with authorization enforced by the backend.

🔑
DEVICE SECURITY

Android Keystore

Device-side sensitive token material is protected using Android platform cryptographic storage.

⚙️
CREDENTIALS

Password Protection

Server-side passwords are protected using bcrypt rather than storing plaintext credentials.

🚦
ABUSE RESISTANCE

Rate Limiting

Protected endpoints use rate-limiting controls to reduce brute-force and abusive request patterns.

🗄️
DATA LAYER

Private Storage & Least Privilege

Application data remains behind the service layer, with media stored separately and access controlled at the filesystem layer.

4C Pulse Secure Architecture

A layered production architecture separates the mobile client, secure edge, application services, database, and media storage.

Modern Security Standards & Practices

4C Pulse development uses established security guidance as a design baseline rather than treating security as a single feature.
