The Challenge

SaaS companies must simultaneously ship product fast, maintain multi-tenant security isolation, manage complex subscription billing, and satisfy enterprise compliance requirements — with an engineering team that is often under-resourced relative to the scope.

Our Solution

We architect SaaS platforms with tenant isolation, usage metering, and enterprise-grade security built into the data model from day one — enabling teams to ship features fast without accruing compliance or architecture debt that slows them later.

Our Approach

Multi-tenant architecture with row-level and schema-level isolation options

Usage metering and subscription billing integrated from the ground up

Enterprise SSO, RBAC, and audit logging as standard deliverables

SaaS Compliance & Security Architecture

Built for the scrutiny of enterprise security reviews, legal teams, and compliance officers.

Compliance Frameworks & Standards

SOC 2 Type IIHigh Impact

Security, availability, processing integrity, confidentiality, and privacy controls attested by an independent auditor. Required by virtually all enterprise customers and many mid-market SaaS buyers.

ISO 27001High Impact

International information security management system standard. Required for many EU and APAC enterprise customers. Demonstrates systematic approach to data security.

GDPR / CCPAHigh Impact

EU and California privacy regulations governing user data collection, consent, retention, and deletion. Applies to any SaaS product used by EU or California residents.

HIPAA (Health SaaS)High Impact

Required for SaaS products handling protected health information. Requires Business Associate Agreements, PHI encryption, and audit logging.

PCI-DSS (Billing)Medium Impact

Required if SaaS handles payment card data. Most SaaS avoids direct card storage by using Stripe/Braintree, but SAQ A compliance is still required.

Built-in Security Practices

NDA & IP Assignment on Day 1

Every engagement starts with a mutual NDA and full IP assignment to the client. Your code, data, and intellectual property remain yours exclusively.

Secure Development Lifecycle

SAST (static analysis), DAST (dynamic scanning), and dependency audits run automatically in CI/CD. Vulnerabilities are triaged before any PR merges to main.

Encryption at Rest & in Transit

All data encrypted with AES-256 at rest and TLS 1.3 in transit. Secrets managed via AWS Secrets Manager, Azure Key Vault, or HashiCorp Vault — never in code.

Role-Based Access & Audit Logs

Least-privilege IAM across all environments. Every access event is logged, retained, and available for your security audits — cloud-native audit trails by default.

Infrastructure Security

Private VPCs, no public-facing databases, WAF on all API gateways, DDoS mitigation via CloudFront/Azure Front Door. Security groups reviewed on every infrastructure change.

Vulnerability Disclosure Process

A documented responsible disclosure programme and defined SLAs for critical findings: Critical (4 hrs), High (24 hrs), Medium (72 hrs). Quarterly penetration testing available.

Security review required by your procurement team?

We maintain a security questionnaire response pack, architecture diagrams, and vendor due-diligence documentation ready to send within 24 hours.

FAQ

Common Questions

A focused MVP typically ranges from $5,000 to $25,000. A full multi-tenant SaaS platform with billing, onboarding, and enterprise-tier features ranges from $70,000 to $150,000+, depending on architecture complexity and integration scope.

Yes, when built on real product usage data — churn prediction models scoring account health in real time let customer success teams intervene before cancellation rather than reacting to it. The model is only as good as the usage-event instrumentation feeding it, which we typically need to build or improve first.

Multi-tenant architecture — tenant isolation, per-tenant customization, and usage-based billing infrastructure — is a core part of our SaaS engineering work, not an afterthought bolted onto a single-tenant codebase.

Yes — this is one of the most common SaaS engagement drivers we see. See our Application Security & DevSecOps Services for the specific SOC 2 readiness and control implementation work.

A focused MVP validating a core value proposition typically takes 8–12 weeks. A full platform with multi-tenant architecture, billing, and onboarding automation ranges from 16–28 weeks.

Both. Early-stage engagements typically prioritize a lean MVP to validate product-market fit; growth-stage engagements add multi-tenant scaling, churn prediction, and compliance architecture. The same engineering standards apply to both, scoped to what's actually needed at each stage.
