When to Upgrade to Paid/Enterprise

You probably need to level up when:

  • You raise Series A+ (€2M+)
  • You handle sensitive data (health, financial)
  • You have compliance requirements (SOC 2, HIPAA, PCI-DSS)
  • You have 50+ employees
  • You're regularly audited

Then consider:

  • Commercial SIEM (Datadog Security, Elastic Security)
  • EDR (CrowdStrike, SentinelOne) instead of just Defender
  • Commercial training (Full KnowBe4, Proofpoint) instead of Riot
  • Vulnerability scanning (Qualys, Tenable) instead of OpenVAS
  • Professional pentests (Annual, €5-15k)
This guide prioritizes:
✅ Free/low-cost options that actually work
✅ Tools startups already use (Google, GitHub, AWS)
✅ Quick setup (< 1 day per tool)
✅ Minimal maintenance overhead
This guide avoids:
❌ €20k GRC platforms
❌ Enterprise-only tools
❌ Complex self-hosted solutions (unless clearly superior)
❌ Tools that require dedicated security engineers
