SOC2 Type II

Overview

A rapidly growing FinTech startup approached Taskew Solutions to develop a sophisticated, AI-driven investment portfolio management platform that would differentiate them in a competitive market. The platform needed to provide real-time portfolio analytics, AI-powered investment recommendations, and automated risk assessment—all while meeting stringent SOC2 Type II compliance requirements for handling sensitive financial data.

Our team designed and built a modern, serverless architecture leveraging Next.js for the frontend, Vercel for edge deployment, MongoDB Atlas for flexible data storage, and AWS S3 for secure document management. The result is a lightning-fast, globally distributed platform that processes millions of data points daily while maintaining the highest security and compliance standards.

The Challenge

The client faced several critical challenges:

  • Regulatory Compliance: Required SOC2 Type II certification to win enterprise clients and institutional partnerships
  • Real-Time Performance: Needed sub-second response times for portfolio analytics across global user base
  • AI Integration: Required sophisticated machine learning models for investment recommendations without sacrificing user experience
  • Data Security: Must protect sensitive financial data and personally identifiable information (PII) with enterprise-grade security
  • Scalability: Platform needed to handle unpredictable traffic spikes during market volatility
  • Document Management: Secure storage and retrieval of financial documents, statements, and regulatory filings

The existing MVP was built on a monolithic architecture that couldn't scale, lacked proper security controls, and had no compliance framework. A complete redesign was necessary.

The Solution

Taskew Solutions delivered a comprehensive platform transformation, rebuilding the application with a modern, serverless-first architecture while simultaneously implementing a full SOC2 compliance program.

Modern Architecture Design

We designed a cutting-edge architecture optimized for performance, security, and scalability:

🌐 Frontend Layer

Next.js 14 with App Router: Server-side rendering, edge functions, and optimized data fetching for lightning-fast user experience. Deployed globally via Vercel's edge network.

API & Business Logic

Next.js API Routes & Serverless Functions: Auto-scaling API endpoints with built-in middleware for authentication, rate limiting, and request validation. AI/ML models integrated via dedicated microservices.

💾 Data Layer

MongoDB Atlas: Flexible document storage with automated backups, point-in-time recovery, and SOC2-compliant encryption at rest. Optimized indexes for real-time portfolio queries.

📦 Storage & CDN

AWS S3 & CloudFront: Secure document storage with versioning, lifecycle policies, and server-side encryption. CloudFront CDN for global distribution of static assets and documents.

🔒 Security & Monitoring

Comprehensive Security Stack: Auth0 for identity management, AWS WAF for DDoS protection, Datadog for monitoring, and automated vulnerability scanning via Snyk and GitHub Advanced Security.

AI-Powered Features

  • Portfolio Optimization: Machine learning algorithms analyze risk tolerance, market conditions, and historical performance to recommend optimal asset allocation
  • Predictive Analytics: Time-series forecasting models predict portfolio performance under various market scenarios
  • Automated Risk Assessment: Real-time risk scoring based on portfolio composition, market volatility, and client-specific parameters
  • Smart Rebalancing: AI-driven recommendations for portfolio rebalancing to maintain target allocation while minimizing tax implications

SOC2 Type II Compliance Program

  • Comprehensive security policy framework covering 5 Trust Service Criteria
  • Multi-factor authentication (MFA) enforced for all users and administrators
  • Role-based access control (RBAC) with least-privilege principle
  • Encryption in transit (TLS 1.3) and at rest (AES-256)
  • Automated vulnerability scanning and patch management
  • Detailed audit logging and SIEM integration
  • Incident response plan with defined SLAs
  • Regular security awareness training for all team members
  • Third-party vendor security assessments
  • Annual penetration testing and security audits
