For early-stage through growth-stage SaaS companies running production AWS workloads. SOC 2, ISO 27001, NIS2, or IRAP-ready architectures. We build environments that pass enterprise security questionnaires without slowing engineering velocity.
Drawn from discovery calls with SaaS founders and CTOs over the last 18 months. If two or three of these sound familiar, we should talk.
Six-figure ARR opportunity hit the security review and stopped. Procurement asks for SOC 2 Type II report, ISO 27001 certificate, penetration test results. You have none of them. Sales cycle stalls 4-6 months while you scramble.
Revenue growing 3× year-over-year. AWS bill growing 4.5× year-over-year. Per-customer COGS climbing instead of dropping. Gross margin is degrading and the board is asking why. Cost optimization is "next quarter" for too many quarters running.
Per-tenant data isolation depends entirely on application-level checks. Database is shared. Cache is shared. No infrastructure-level defense in depth. One bug or misconfiguration risks cross-tenant data leak — the kind of incident that ends companies.
Black Friday, end-of-quarter, end-of-month, demo day — predictable load spikes that still cause outages. Database connection pools exhausted, EKS pods can't schedule, Lambda concurrent execution limits. Same incidents repeating quarter after quarter.
CloudWatch for AWS metrics, Datadog for APM, Sentry for errors, Splunk for logs, custom dashboards for business metrics. Every incident requires bouncing between tools. Mean time to resolution is twice what it should be because nobody can see the whole picture.
The technical co-founder built the AWS infrastructure. They're now spending 40% of their time on operations instead of product. The very person who needs to be focused on differentiation is firefighting infrastructure. Hiring a senior DevOps engineer is taking 6 months you don't have.
SaaS compliance is sales-driven. Every framework you complete opens new buyers. SOC 2 unlocks US enterprise. ISO 27001 unlocks EU enterprise. NIS2 unlocks regulated EU. IRAP unlocks Australian government. Each pays for itself in deal velocity.
The dominant US enterprise security audit. Trust Service Criteria around security, availability, processing integrity, confidentiality, privacy. Most US enterprise procurement requires it. Type II requires 6+ months of evidence.
Discuss SOC 2 prep →Information security management baseline. Required by most EU enterprise procurement. We hold ISO 27001:2022 ourselves — meaning we operate the standard, not just recommend it.
ISO 27001 implementation →EU Network and Information Systems Directive 2. Affects SaaS in essential or important services categories. Supply chain security, incident notification within 24-72 hours, management body accountability.
NIS2 implementation →If you process EU resident personal data — which most SaaS does. Region selection, data processor agreements, lawful basis documentation, right-to-deletion implementation. Enterprise procurement scrutinizes this in detail.
GDPR architecture →Information Security Registered Assessors Program. Required for selling SaaS to Australian government and defense. PROTECTED-level assessment is the typical target. AWS Sydney holds IRAP, but customer responsibilities apply.
IRAP architecture →Australian Cyber Security Centre's prioritized mitigations. ML2 (Maturity Level 2) is typically the SaaS target. Application control, patch management, MFA, restrict admin privileges. Maps to AWS configurations.
Essential Eight implementation →Most SaaS engagements combine two or three of these. A typical growth-stage SaaS engagement: cost optimization + DevSecOps + SOC 2 prep. A typical early-stage company: DevOps capacity + ISO 27001 baseline + multi-tenant isolation review.
SaaS-specific cost patterns: per-customer COGS analysis, RDS right-sizing, EKS efficiency, observability cost, multi-region overhead. Typical engagement: 20-35% cost reduction in Q1, gross margin recovery within 2 quarters.
Cost optimization →SAST/DAST gates, IaC scanning, container security, SBOM generation. Continuous instead of annual pen-test. Audit evidence collected automatically. Critical for SOC 2 / ISO 27001 prep.
DevSecOps service →Augment your DevOps function. ECS, EKS, CodePipeline, Terraform. Multi-tenant isolation patterns built-in. Same engineers retained across months, not body-shop rotations. Free up your founder-engineer.
DevOps service →Architecture and operational evidence for SOC 2 Type II and ISO 27001:2022 audits. Encryption, access controls, audit logging, incident response procedures. Audit-ready from day one, not retrofitted.
ISO 27001 implementation →24/7 managed operations with documented runbooks, incident response, audit evidence collection. Pro tier suits most SaaS scale-ups; Enterprise tier for revenue-critical workloads with SLA commitments.
CloudOps service →SaaS scale-ups frequently outgrow Heroku at early stage. Heroku to AWS migrations preserving Postgres, redesigning for ECS/EKS, with cost analysis showing 4-7 month payback. Multi-tenant patterns added during migration.
Heroku to ECS →Different growth stages have different AWS architecture patterns. Honest advice: don't over-engineer for stages you haven't hit yet, and don't under-engineer for the stage you're already in.
One AWS region. ECS Fargate or EC2 deployment. Single-AZ RDS for cost. CodePipeline for CI/CD. Multi-tenant via application logic. SOC 2 Type I or ISO 27001 baseline started. AWS bill: typically $2.5-10k/month. First enterprise deals typically appear at early stage.
Multi-AZ deployment for production. RDS Multi-AZ with read replicas. EKS for stateful services. AWS WAF, GuardDuty, Security Hub. SOC 2 Type II achieved, ISO 27001 in progress. First six-figure ARR enterprise deals. AWS bill: typically $19-62k/month.
Active-active or active-passive multi-region. Aurora Global Database. Comprehensive observability. SOC 2 Type II + ISO 27001 + NIS2 + sector-specific (IRAP / FedRAMP) where applicable. Mature FinOps with Reserved Instance and Savings Plan portfolio. AWS bill: typically $100-375k/month.
Most AWS partners say "we work with SaaS" because every consultancy does. The structural differences below are why SaaS buyers actually choose us.
HAZERCLOUD INFOTECH LLP holds ISO 27001:2022. We're not just helping you implement the standard — we live inside the audit cycle ourselves. The same procedures we recommend, we operate. That's structural credibility, not marketing claim.
We've built audit-ready AWS environments for SaaS scale-ups going through SOC 2 Type II and ISO 27001 cycles. Audit evidence collection, control mapping, gap analysis, auditor questions. We've answered them before, on engagements that completed.
SaaS architecture decisions hinge on multi-tenant isolation strategy. Database-per-tenant vs. row-level security vs. schema-per-tenant. Encryption-by-tenant vs. shared keys. Cache isolation. We've made these decisions for SaaS clients and know the trade-offs by stage.
We don't run the body-shop economics. Our engagement model requires founder-attended weekly reviews, which structurally caps how many concurrent engagements we can run. The result: AWS-certified engineers actually doing the work, not just selling the discovery call.
No sales pitch. We'll walk through your current AWS environment, identify the highest-leverage gaps for your funding stage, multi-tenancy architecture, and enterprise compliance posture (SOC 2, ISO 27001), and tell you honestly whether we're a fit. If we're not, we'll suggest who is.
