AWS Security Baseline for Startups in India

The 12 AWS security controls every Indian seed startup should turn on this afternoon — region-locked to ap-south-1, DPDP-aware, RBI-overlay-ready. Same opinionated baseline we open-sourced as aws-startup-security-baseline. Built for ₹40k-month retainers, not enterprise CAPEX.

3 days for the baseline apply, 10 days for India-specific hardening, plus optional monthly retainer for ongoing tuning

The Problem

Indian seed startups inherit AWS Console defaults that were designed for US-based enterprises. Default region us-east-1 (which violates DPDP localization for any Indian-user data). Default S3 ACLs that allow accidentally-public buckets. No CloudTrail (so when something breaks at 2 AM you have no audit trail). No GuardDuty (so cryptominers running on your account go undetected for weeks). The fix isn't 200 CIS controls — it's the 12 that prevent the most painful failure modes for a 5-engineer team. We open-sourced our exact baseline at github.com/avinash-matrixgard/aws-startup-security-baseline. This page is the engagement that ships and tunes it for your specific account.

Who This Is For

Pre-seed to Series A startups (5-30 engineers) running production workloads on AWS, headquartered in or serving Indian users. Especially relevant if you're (a) about to raise / about to ship to your first enterprise customer / about to face a customer security questionnaire, or (b) an Indian fintech / healthtech / B2C SaaS where DPDP and RBI overlays add specific Indian requirements on top of the generic AWS baseline.

Typical Outcomes

Total monthly AWS security tooling cost: ~$10-40 USD (~₹800-3,500) at startup scale — less than one engineer's lunch budget
DPDP data localization defensible — every personal data field traceable to an India-region store
Customer security questionnaires answered in hours instead of days — the baseline ships with the evidence pack
GuardDuty + Security Hub findings triaged and routed, not just enabled-and-ignored
Engineering velocity preserved — security gates fail-soft (warn, don't block) by default until you're ready to tighten them
Account ready for Series A technical due diligence on the security side

Timeline Options

Baseline Apply (3 days)

  • Terraform applied for all 12 controls via IaC, no Console clicks
  • SNS topic + email subscription confirmed, alerts flowing
  • AFSBP findings reviewed, top 10 prioritized for next sprint
  • 30-min handover briefing for your tech lead
Most Popular

Baseline + India-Specific Hardening (10 days)

  • Everything in Baseline Apply
  • Region-lock SCPs deployed
  • DPDP data-classification tagging across all data stores
  • Incident response runbook tailored to your stack
  • Cost-review template + first month's review delivered

Baseline + Hardening + Monthly Retainer (10 days + monthly)

  • Everything in Baseline + India-Specific Hardening
  • Monthly retainer covering: AFSBP finding triage, quarterly access reviews, monthly cost reviews, IAM access analyzer remediation, Security Hub standard updates
  • Direct Slack channel with the MatrixGard team
  • First-year coverage of any new AWS service rollouts that affect baseline (e.g., new GuardDuty data sources)

This might not be a fit if...

  • You operate exclusively outside India and DPDP / RBI don't apply (the generic open-source baseline is enough — clone the repo)
  • You're at Series C+ with a dedicated cloud security team (you've outgrown a baseline; you need a security architect)
  • You're not on AWS (we cover GCP and Azure under separate engagements; this page is AWS-specific)
  • You want a generic CIS Benchmark application (the whole point of our baseline is opinionated reduction — if you want all 140 controls, our open-source repo's skip-list explains why we don't ship them)

What You Get

12 controls deployed as Terraform: IAM password policy, root MFA enforcement alarms, multi-region CloudTrail with KMS encryption, S3 account-level public access block, GuardDuty, Security Hub + AFSBP standard, IAM Access Analyzer, default EBS encryption, default-VPC Flow Logs, AWS Config recorder, Cost Anomaly Detection, AWS Budgets monthly cap
Region-lock enforcement — IAM SCP / Service Control Policies preventing resource creation outside ap-south-1 (or any other approved India region) for any account handling Indian-user data
DPDP-aware data-classification tagging — every S3 bucket / RDS instance / EBS volume tagged with data-residency requirement, automated audit job flagging anything with personal data outside India
RBI overlay (where applicable) — additional controls for fintech use cases: KMS rotation cadence, audit-log retention, HSM-backed key generation if required by your license category
CloudWatch + GuardDuty + Security Hub alerts wired to a single SNS topic delivered to your team's Slack / PagerDuty / email
Cost monitoring stack — AWS Cost Anomaly Detection + Budgets with INR-context thresholds (we work in rupees not abstract dollar amounts), monthly cost-review template
Incident response runbook covering the top 5 failure modes specific to Indian startups (S3 leak, IAM compromise, runaway compute, DDoS, data-residency violation)
Handover documentation in our standard format — every control documented with what it does, why it matters, what breaks if you skip it, when to graduate off it

The Transformation

Before

  • Account default region us-east-1 — DPDP localization invisible to anyone reading the AWS Console
  • S3 buckets created at random, some public, no account-level guardrail
  • No CloudTrail — when something happens at 2 AM there's no record of who did what
  • Root account used for routine deploys, MFA optional
  • No cost alerting — you find out about a $4,000 surprise charge from the monthly invoice

After

  • All resources locked to ap-south-1 via SCP, DPDP localization defensible to auditors
  • Account-level S3 public access block enforced — no accidentally-public buckets possible, even by mistake
  • CloudTrail multi-region with KMS encryption, log file validation, immutable audit trail
  • Root MFA enforced + alarmed, console-no-MFA login alerts firing within 5 min
  • AWS Cost Anomaly Detection + Budgets with INR-aware thresholds, surprise charges caught within 24 hrs

Incident Readiness

When production breaks, does your team have a playbook, or does everyone just Slack the one person who knows the system? We build the runbooks, alerts, and processes so the next incident doesn't become a war story.
