Security Framework
Executive Summary
Eli operates a security-first architecture built on a fundamental principle: carefully select the most secure cloud providers and let them handle what they do best. Rather than attempting to reinvent security infrastructure, we focus our expertise on application-level security while leveraging enterprise-grade providers who specialize in infrastructure protection. This approach delivers superior security outcomes compared to self-managed alternatives.
Defense-in-Depth Security Strategy
Infrastructure Security (Provider-Managed)
- DDoS protection via Vercel's global CDN and AWS infrastructure
- Network-level security filtering and threat detection
- Automatic security patching for underlying infrastructure
- Geographic redundancy across multiple availability zones
Application Security (Eli-Managed)
- Type-safe API design preventing injection attacks
- Comprehensive authentication and authorization controls
- End-to-end encryption for all data transmission
- Secure development lifecycle with automated security scanning
Core Security Domains
Our security framework is organized across four key operational areas, each detailed in dedicated documentation:
- Multi-method authentication and identity management
- Role-based access control and authorization
- API security architecture and session management
- Encryption standards and key management
- Data isolation and backup strategies
- Recovery and business continuity procedures
- Security monitoring and threat detection
- Incident response procedures and escalation
- Disaster recovery and uptime commitments
Infrastructure & Application Security
Cloud Provider Security (Inherited)
- Vercel/AWS: DDoS protection, WAF filtering, infrastructure monitoring
- MongoDB Atlas: Automated security patching, network isolation, backup encryption
- Firebase/Google Cloud: Identity and access management, audit logging, compliance certifications
Application Security by Design
Secure Development Practices
- TypeScript for compile-time security validation
- Zero-warning linting policy enforcing security best practices
- Automated dependency vulnerability scanning
- Code review requirements for all changes
Runtime Protection
- tRPC type-safe remote procedure calls eliminating injection vulnerabilities
- Prisma ORM with parameterized queries preventing NoSQL injection
- CORS policies restricting cross-origin requests to authorized domains
- Input validation and sanitization at API boundaries
- Content Security Policy (CSP) headers
Compliance & Certifications
Industry Standards
- SOC 2 Type II readiness (provider certifications inherited)
- ISO 27001 alignment through cloud provider certifications
- GDPR technical and organizational measures compliance
- Industry-specific security requirements support
Vulnerability Management
Automated Scanning
- Dependency vulnerability scanning in CI/CD pipeline
- Static code analysis for security issues
- TypeScript compile-time security validation
Patch Management
- Automatic security updates for cloud infrastructure (provider-managed)
- Rapid application patching for identified vulnerabilities
- Zero-downtime deployment capability for emergency patches
- Staging environment testing for all security updates
