Overview
Security architecture ensures systems are secure by design rather than patched later. We produce security architectures covering identity, network, data protection, key management, logging and resilience — for cloud platforms, fintech systems, AI applications and Web3 infrastructure — documented with threat models and control mappings.
Common use cases
- New platform security designSecurity architecture for a new system.
- Fintech security architectureControls for financial systems.
- Web3 security architectureKeys, contracts and infrastructure.
- AI system securityData boundaries and model access controls.
Quick answers
Security Architecture at a glance
The essentials in brief. Every project is scoped individually — ask us for specifics.
- What is security architecture?
- Security architecture for applications, cloud, fintech and Web3 systems — defence in depth by design.
- Who is it for?
- Typically companies migrating to the cloud, teams whose releases are slow or risky, and organisations that need stronger reliability, security or cost control.
- What does Shivacha provide?
- Threat modelling
- Reference architectures
- Control mapping
- Data protection design
- Key management design
- Architecture reviews
- Which technologies are used?
- OWASP, HashiCorp Vault, Keycloak, OAuth 2.0 & OIDC, Amazon Web Services, Microsoft Azure — chosen to fit your stack and constraints.
- How does the process work?
- Assess → Prioritise → Implement → Test → Monitor.
- What affects the cost?
- Number of applications and environments
- Compliance and data-residency requirements
- Availability and recovery objectives
- Existing automation and IaC maturity
- Multi-cloud or hybrid scope
- Ongoing managed-service needs
- How long does it take?
- Assessments take 2–4 weeks; platform builds and migrations are usually delivered in 2–6 month phases.
- How do I get started?
- Share a short brief in the form below, book a 30-minute call or message us on WhatsApp. A senior engineer replies within one business day; NDA on request.

Architecture
Engineered right from day one
The layers we typically design for cybersecurity, adapted to your stack and partners.
- Shift leftSecurity checks in pipelines catch issues before production.
- Identity is the perimeterStrong identity and least privilege over network trust.
- Framework-alignedControls mapped to ISO 27001, SOC 2 or PCI DSS where relevant; certification by accredited auditors.
- Practised responseIncident runbooks rehearsed, not just written.
Delivery
How an engagement runs
- 1
Assess
Threat model, current controls and gaps against relevant frameworks.
- 2
Prioritise
Risk-ranked roadmap focused on the highest-impact controls first.
- 3
Implement
Controls built into infrastructure, pipelines and applications.
- 4
Test
Penetration tests, configuration reviews and attack simulations.
- 5
Monitor
Continuous detection, alerting and incident response procedures.
Security
Security built into delivery
Controls we apply by default on this kind of work — not a separate phase at the end.
Infrastructure as code
Every change reviewed, versioned and reproducible.
Identity & network
Least-privilege IAM, private networking and zero-trust access.
Secrets & encryption
Central secrets management and encryption by default.
Monitoring
Alerting, audit logs and incident runbooks from day one.

Frequently asked questions
When should security architecture be involved?
From initial design; changes are far cheaper before implementation.
Can you review our architecture?
Yes, with prioritised recommendations and a remediation roadmap.
Is Shivacha a certified security firm?
Shivacha does not currently claim security certifications. We implement technical controls and security engineering; where certification or attestation is required, it is performed by accredited third parties.
Do you offer penetration testing?
Yes, as part of security engineering engagements — scoped application, API and cloud testing with remediation guidance and re-testing.
