Architecture, Security &
Engineering Excellence
From secure system design to production deployment — we provide the full spectrum of enterprise software architecture and cybersecurity services.
Enterprise Modern Web
Application Development
We don't build websites — we engineer enterprise-grade web applications designed for massive scale, uncompromising security, and long-term technical sustainability. Every system we deliver is architected for growth, hardened against threats, and built to perform under real-world production demands.
Scalable Front-End & Back-End Architectures
React, Next.js, Vue, Angular for front-end. Java and Spring Boot for the back-end, with Node.js, Go, and .NET where they fit better. Designed for horizontal scale from day one.
Secure API Design & Microservices
RESTful and GraphQL APIs with OAuth 2.0, rate limiting, input validation, and comprehensive audit logging. Microservices with event-driven communication.
Cloud-Native & On-Premise Deployments
ArvanCloud, AWS, Azure, GCP, or air-gapped on-premise — we deploy where your compliance and performance requirements demand. Kubernetes, Docker, Terraform.
High-Performance, Resilient Systems
Load balancing, caching strategies, database optimization, CDN integration, and circuit breaker patterns for systems that never go down.
Built for Long-Term Maintainability
Clean architecture, comprehensive documentation, automated testing suites, and dependency management strategies that keep systems healthy for years.
Security Woven Into Every Layer
Threat modeling during design, SAST/DAST in CI/CD, runtime protection, and continuous vulnerability monitoring — security is never an afterthought.
Secure Software Architecture & Engineering
Security vulnerabilities are architectural failures. We design systems where security is a structural property — not a checkbox. Every architecture decision we make considers attack vectors, data flow protection, and long-term defensibility.
- Attack surface analysis and reduction strategies
- Secure coding practices and code review frameworks
- Zero-trust architecture implementation
- Long-term maintainable architecture design with ADRs
- Data encryption at rest and in transit
Security Architecture Principles
DevSecOps & Secure SDLC Integration
Security testing should happen on every commit, not once a quarter. We integrate automated security gates directly into your development pipeline — making secure delivery the default, not the exception.
- Automated SAST, DAST, and dependency scanning
- CI/CD pipeline hardening and secret management
- Container image scanning and runtime protection
- Secure deployment pipelines with approval gates
- Infrastructure as Code security validation
Pipeline Security Gates
Threat Modeling & Architectural Risk Analysis
The cheapest vulnerability to fix is the one that never reaches code. We conduct rigorous threat modeling sessions that identify attack scenarios and drive risk-aware design decisions — before the first line of code is written.
- STRIDE and PASTA threat modeling methodologies
- Attack tree analysis and scenario mapping
- Data flow diagrams and trust boundary analysis
- Risk-driven architectural design recommendations
- Prioritized risk register with mitigation strategies
Threat Modeling Framework
Penetration Testing & Security Assessments
Assumptions are vulnerabilities. Our penetration testing team simulates real-world attack scenarios against your systems — delivering actionable findings with clear remediation paths, not generic scanner output.
- White Box testing with full source code access
- Gray Box testing with partial system knowledge
- Black Box testing simulating external threat actors
- Web application and API security assessments
- Detailed remediation guidance with severity scoring
Testing Methodology
Infrastructure Hardening & High Availability Design
Your infrastructure is only as strong as its weakest configuration. We design and harden production environments for security, resilience, and operational excellence — with comprehensive disaster recovery strategies.
- Server and network configuration hardening (CIS benchmarks)
- Disaster recovery planning and testing
- Multi-region and multi-AZ resilient architectures
- Monitoring, alerting, and incident response automation
- Database replication and backup strategies
Availability Targets
Legacy System Modernization
Legacy systems are liability systems. We help organizations securely refactor, re-architect, and migrate aging systems into modern, maintainable architectures — without disrupting business operations.
- Comprehensive legacy system assessment and risk analysis
- Strangler fig pattern for incremental migration
- Database migration and data integrity validation
- API gateway integration for legacy system abstraction
- Zero-downtime migration strategies
Migration Strategy
SOC Setup & Strategic Security Consulting
Security operations require more than tools — they require strategy, process, and skilled execution. We help organizations build and operationalize Security Operations Centers and develop comprehensive security programs.
- SOC architecture and SIEM implementation
- Incident response playbook development
- Security program maturity assessments
- CISO advisory and security roadmap development
SOC Capabilities
CMS & Platform-Based Solutions

WordPress Development
Custom theme and plugin development with security-first configuration and performance optimization.
CMS Customization
Tailored configurations for Drupal, Strapi, Contentful, and other CMS platforms to meet specific business requirements.
Security Hardening
Plugin audits, access control, WAF configuration, and vulnerability patching for existing CMS installations.
Performance Optimization
Caching strategies, CDN integration, database optimization, and Core Web Vitals improvement.

Frequently Asked Questions
Answers to questions we hear most often from CTOs, CISOs, and engineering leaders before starting an engagement.
We serve organizations across fintech, healthcare, SaaS, government, logistics, and enterprise software. Our methodology is industry-agnostic — what varies is the specific compliance and threat landscape we design for (HIPAA, PCI-DSS, FedRAMP, SOC 2, ISO 27001, etc.).
Discovery and architecture design typically run 4–6 weeks. Full-cycle delivery of a complex enterprise application ranges from 4 to 12 months depending on scope, integrations, and compliance requirements. We work in iterative sprints so you see working software continuously throughout the engagement.
A vulnerability assessment identifies and classifies potential weaknesses. A penetration test goes further — our engineers actively attempt to exploit those weaknesses the way a real adversary would, providing evidence of business impact and a prioritized remediation roadmap. We offer White Box, Gray Box, and Black Box methodologies depending on your objectives.
Yes. Many clients engage TechVault on a fractional CISO or security advisory retainer after an initial engagement. This includes quarterly architecture reviews, ongoing threat modeling as your system evolves, security training for your engineering teams, and incident response readiness planning.
We conduct an initial pipeline audit, then layer security tooling directly into your existing workflow — SAST/DAST scanners, dependency auditing, secrets detection, container image scanning, and IaC policy enforcement. Tools are selected for your stack: GitHub Actions, GitLab CI, Jenkins, CircleCI, or others. The goal is zero-friction security with no separate approval gates.
Yes — and we strongly advise against big-bang rewrites. Our modernization approach uses the Strangler Fig pattern to incrementally extract services, build API boundaries, and migrate functionality without downtime or business disruption. We preserve institutional knowledge while systematically eliminating technical debt.
