SaaS Startup Security: The 30-Day Checklist Before Series A

2026-06-13 8 min read

Investors and enterprise buyers ask the same questions. Here is the 30-day plan to answer them — without slowing the team down.

Why this matters now

Series A diligence and enterprise procurement both ask the same questions: do you have SSO, MFA, encryption, logging, an incident response plan, and a recent independent pentest? Missing answers delay both.

The good news: a focused 30-day sprint covers 80% of what enterprise security questionnaires demand.

Week 1: foundations

Inventory production assets, owners and data flows. Enforce MFA for every admin console (cloud, DNS, Git, CI, support tools). Lock down root accounts and rotate any shared secrets.

Write a one-page security policy and an incident response runbook. These two artefacts unlock a surprising number of questionnaires.

Week 2: identity and data

Enable SSO for your customer-facing app (even on a paid plan — buyers will pay for it). Implement role-based access. Force TLS 1.2+ everywhere and encrypt PII at rest.

Map your subprocessors and publish a public list. Buyers want one URL they can link in their vendor review.

Week 3: testing and monitoring

Turn on cloud-native logging (CloudTrail, GuardDuty or equivalent). Wire alerts to a Slack channel and assign an owner.

Run a third-party pentest. A PTaaS engagement gives you a clean PDF, a retest, and a live portal buyers can be invited to.

Week 4: paperwork

Stand up a trust page with your pentest letter, subprocessors, SLAs, security overview and a contact for vulnerability reports.

Start the SOC 2 Type I clock. With everything above in place, the controls are mostly already in production.
