Most Sunnyvale startups handle IT the same way in the early days: a technical co-founder manages the Google Workspace account, someone’s personal AWS account hosts the dev environment, and “security” means a shared LastPass login. It works until it doesn’t.

The inflection point usually comes around 10–15 employees, a Series A, or the first enterprise sales conversation where a prospect sends a security questionnaire. Suddenly, informal IT becomes a liability.

Here’s how to build IT infrastructure that doesn’t require a painful rebuild six months from now.

Start with Identity — Not Tools

The most important IT decision a startup makes is the identity platform. Everything else is downstream from it.

Microsoft 365 with Entra ID or Google Workspace are the two realistic options for most Sunnyvale startups. Both work. The deciding factors are usually:

  • What your team already uses
  • Whether your enterprise customers expect M365 compatibility
  • Whether you plan to use Windows or Mac endpoints at scale (M365 + Intune handles Windows device management significantly better)

Whichever you choose, set it up correctly from day one:

  • MFA enforced for all users — not optional, not “encouraged”
  • Conditional Access policies (M365) or context-aware access (Google) that block access from unmanaged or untrusted devices
  • Domain-based email — not gmail.com addresses on a business domain, but properly configured Exchange Online or Google Workspace email with SPF, DKIM, and DMARC records
  • Separate admin accounts — your CEO should not have a global admin account that they use for daily email

If you’re starting with M365, our Microsoft 365 security baseline post covers the specific settings worth configuring on day one.

Cloud Infrastructure: Dev vs. Production

Most Sunnyvale startups have a product infrastructure question mixed in with their internal IT question. They’re different problems.

Product infrastructure (AWS/GCP/Azure for your SaaS product, CI/CD pipeline, databases) is generally owned by engineering. An MSP isn’t the right vendor here — your DevOps engineer or a specialized cloud consultant is.

Internal IT infrastructure (laptops, identity, email, file storage, communication tools, security tooling) is what a managed IT provider handles. If you’re using a personal AWS account for an internal file share or running your own email server, that’s a red flag — not because it can’t work, but because it rarely gets the maintenance attention it needs alongside a shipping product.

Keep these two concerns separated organizationally.

The Security Baseline You Need Before a Series A

Enterprise customers and serious VCs will ask about your security posture. Here’s the minimum credible baseline for a Sunnyvale startup:

Endpoint management — every company-issued device should be enrolled in a device management system (Intune for Windows/M365, Jamf or Apple Business Manager for Macs). This gives you remote wipe capability, enforced disk encryption, and a software deployment channel.

Endpoint protection — Microsoft Defender for Business is included with M365 Business Premium and is genuinely good. For Google Workspace shops, you’ll need a third-party EDR. Huntress is strong for SMBs.

Backup — M365 and Google Workspace are not backups. Both platforms have version history and recycle bins, but neither protects against ransomware that syncs encrypted files to the cloud. You need a third-party backup solution with point-in-time restore: Veeam, Spanning, or Backupify are common choices.

Access reviews — quarterly is fine for a startup. Who has admin access to what? Are any former employees still active? Is anyone using a personal account for company resources?

Incident response basics — you don’t need a 40-page IR plan. You need to know: who do you call if you get hit with ransomware? What’s the escalation path? Have you tested your backups in the last 90 days?

When to Bring in a Managed IT Provider

The honest answer: earlier than most Sunnyvale startups do.

The cost of a managed IT provider at 10 employees ($1,000–$1,500/month typically) is far lower than the cost of recovering from a security incident, rebuilding a misconfigured M365 tenant, or losing engineering time to IT issues that aren’t engineering problems.

Good signals that it’s time:

  • Engineers are spending meaningful time on IT support tickets
  • You’ve had at least one security scare (phishing email, credential exposure, unauthorized access attempt)
  • A customer or investor has asked about your security posture and you weren’t sure how to answer
  • You’re onboarding more than 2 new employees per month and offboarding isn’t documented

Bad signals that you should wait:

  • You have fewer than 5 employees and a technical founder who enjoys managing infrastructure
  • Your entire team is remote on personal devices with no company data on endpoints (though this should change quickly)
