AWS Cloud Security for SaaS Companies
We build AWS security architectures for SaaS companies that pass enterprise customer security reviews, achieve SOC 2 Type II, and enforce tenant data isolation — because for SaaS, your security IS your product.

Summary
Build enterprise-grade security for multi-tenant SaaS on AWS. SOC 2 Type II architecture, tenant data isolation, SSRF protection, and customer-facing security posture documentation.
Key Facts
- • Build enterprise-grade security for multi-tenant SaaS on AWS
- • SOC 2 Type II architecture, tenant data isolation, SSRF protection, and customer-facing security posture documentation
- • Tenant isolation must be enforced at the database, storage, and API layer
- • SOC 2 Type II for Customer Trust: Enterprise SaaS buyers require SOC 2 Type II reports before signing contracts
- • Building the operational evidence over 12 months requires security controls in place from the start

Frequently Asked Questions
How do you enforce tenant data isolation in a SaaS database?
The architecture depends on your isolation model. For pool isolation (all tenants share tables): DynamoDB with tenant-ID partition keys and IAM conditions on access, or RDS with Row Level Security policies enforcing tenant-ID filtering. For silo isolation: separate databases or schemas per tenant. We also implement API-layer enforcement — every request validates the calling tenant's JWT against the resource's tenant ID before returning data.
What is the fastest path to SOC 2 Type II for a SaaS company?
Start security controls now — SOC 2 Type II requires a 12-month observation period. The fastest path: (1) implement core AWS security controls (GuardDuty, Security Hub, CloudTrail) today, (2) get SOC 2 Type I at month 6 to satisfy immediate customer requests, (3) complete Type II at month 18. Consider Vanta or Drata for compliance automation to reduce the manual evidence collection burden.
How do we protect against SSRF attacks targeting AWS metadata?
Enforce IMDSv2 on all EC2 instances and ECS task definitions (requires token-based metadata requests that SSRF exploits cannot perform). In Lambda, there is no IMDS endpoint — Lambda functions access AWS services via IAM execution roles. For EKS, use Pod Identity instead of IMDS-based node roles. We audit all compute configurations for IMDSv1 endpoints using AWS Config custom rules.

Key Challenges We Solve
In a multi-tenant SaaS, a security vulnerability that allows one tenant to access another's data is an existential risk. Tenant isolation must be enforced at the database, storage, and API layer.
Enterprise SaaS buyers require SOC 2 Type II reports before signing contracts. Building the operational evidence over 12 months requires security controls in place from the start.
SaaS platforms are targeted with SSRF attacks (server-side request forgery to access AWS metadata) and credential stuffing attacks on login flows. AWS IMDSv2 and WAF bot control mitigate these.
Enterprise customers ask detailed security questions. Having documented AWS security architecture, penetration test reports, and a security FAQ reduces sales cycle friction.
Our Approach
Tenant Isolation Architecture
DynamoDB partition key-based tenant isolation, per-tenant KMS encryption keys, IAM role assumption for tenant-scoped S3 access, and API Gateway authorizers that reject cross-tenant requests at the perimeter.
SOC 2 Operations Foundation
Security Hub SOC 2 standard monitoring, CloudTrail and CloudWatch Logs with 1-year retention, GuardDuty threat detection, automated access review processes, and change management records — all required for SOC 2 Type II evidence collection.
IMDSv2 & Bot Control
Enforce IMDSv2 on all EC2 and ECS instances to prevent SSRF-based metadata exploitation, WAF Bot Control for rate limiting login endpoints, and Cognito advanced security features for account takeover protection.
