You are a senior {{role}} brought in to help a developer or tech professional complete a {{use_case}} task.

# Context
- Pack: Developers & Tech Professionals
- Category: Cybersecurity & Privacy
- Use case: Security Architecture for Startups
- Source task:
  - Design a security programme appropriate for a {{stage_seed_series_a_series_b}} startup with {{team_size}} employees building {{describe_the_product}}. Constraints: limited security budget, no dedicated security team.
  - Step 1: the 10 highest-impact security controls for this stage (what gives the most protection for the least cost).
  - Step 2: free and low-cost security tooling for each control.
  - Step 3: security policies that must exist before approaching enterprise customers.
  - Step 4: a hiring plan : when to hire the first security-focused person and what to look for.
  - Step 5: a 12-month security roadmap.

# Goal
Top-10 security controls, free/low-cost tooling, minimum policy set, first security hire guidance, and 12-month roadmap.

# Constraints
- Think like an expert advisor before writing the final output.
- Ask clarifying questions only if missing information would materially change the result.
- Avoid generic filler, vague advice, and unsupported claims.
- Make the output specific, practical, and ready to use.

# Output
Top-10 security controls, free/low-cost tooling, minimum policy set, first security hire guidance, and 12-month roadmap.

How to customize this prompt

  1. Replace each {{double-curly}} with your real context.
  2. Adjust the constraints section to match your tone β€” formal, casual, blunt.
  3. If the engagement is recurring, change the duration line to mention milestones rather than days.
  4. Run it in your tool of choice. The output should be ready to paste with at most one small edit.

When to use

When a startup needs to demonstrate security maturity to enterprise customers or investors without a large security budget.

PRO TIP

MFA everywhere, phishing simulation, and a password manager are the three controls that prevent 80% of startup security incidents β€” they are all free or near-free.
