IT Infrastructure for Remote Teams: A Practical Setup Guide
The shift to remote and hybrid work isn’t a trend — it’s the new baseline. But while large companies have IT departments handling the transition, small businesses are often left figuring it out themselves. The result: employees accessing company data over unsecured connections, files scattered across personal Dropbox accounts, and zero visibility into who has access to what.
Here’s a practical guide to setting up IT infrastructure that actually works for small remote teams.
The Foundation: What Every Remote Team Needs
At minimum, a remote team needs four things working together:
1. Centralized File Storage (NAS)
A NAS (Network Attached Storage) is your team’s shared drive, accessible from anywhere. Unlike cloud-only solutions, you own the hardware and the data.
Why NAS over pure cloud?
- One-time cost vs. recurring subscription
- Full control over data (GDPR compliance)
- Faster access for large files within the office
- Automatic local + cloud backup
Recommended setup: Synology DS423+ with 2x 4TB drives in RAID 1 (mirrored). Cost: ~€550 for the NAS + ~€200 for drives.
Enable QuickConnect or set up a reverse proxy for secure remote access without exposing your network.
2. VPN (Virtual Private Network)
A VPN creates an encrypted tunnel between your employees’ devices and your office network. This means:
- Secure access to internal resources (NAS, printers, intranet)
- Encrypted traffic on public Wi-Fi
- Company data never passes through third-party servers
Best options for small businesses:
| Solution | Pros | Cons | Cost |
|---|---|---|---|
| WireGuard | Fast, modern, easy to configure | Newer, less documentation | Free |
| OpenVPN | Battle-tested, wide compatibility | Slower than WireGuard | Free |
| Tailscale | Zero-config, mesh networking | Relies on coordination server | Free for small teams |
My recommendation: WireGuard for teams with some technical capacity, Tailscale for teams that want zero configuration.
3. Backup Strategy
Remote work multiplies the number of devices holding company data. Your backup strategy needs to account for:
- Office NAS — backed up to cloud (Backblaze B2, ~€5/month per TB)
- Employee laptops — backed up to NAS via Synology Active Backup
- Cloud services (Google Workspace, Microsoft 365) — backed up separately
Follow the 3-2-1 rule: 3 copies, 2 different media, 1 off-site.
4. Access Control
Who can access what? This is where most small businesses fail. At minimum:
- Individual accounts — no shared passwords, ever
- Two-factor authentication (2FA) on everything
- Principle of least privilege — employees get access to what they need, nothing more
- Offboarding process — when someone leaves, their access is revoked immediately
Security Essentials
Remote work expands your attack surface. These are non-negotiable:
Device Security
- Full disk encryption on all company devices
- Automatic OS updates enforced
- Antivirus/endpoint protection
Network Security
- Firewall on the office router (not just the ISP’s default)
- Separate VLANs for IoT devices and guest Wi-Fi
- DNS filtering (free options: NextDNS, Pi-hole)
Email Security
- SPF, DKIM, and DMARC configured on your domain
- Phishing awareness training for all employees
What to Outsource vs. Manage In-House
| Task | In-House | Outsource |
|---|---|---|
| Day-to-day support (password resets, etc.) | ✓ (if you have someone technical) | ✓ (monthly retainer) |
| Initial setup (NAS, VPN, network) | ✓ | |
| Security monitoring | ✓ | |
| Backup verification | ✓ (monthly check) | ✓ (included in retainer) |
| Hardware procurement | ✓ (consultant recommends, you buy) |
For teams of 5-30 people, the sweet spot is usually: outsource the setup and security, manage the day-to-day internally with a monthly support retainer for when things break.
Cost Summary
| Component | One-Time Cost | Monthly Cost |
|---|---|---|
| NAS + drives | €750-1,200 | — |
| VPN setup | €200-500 | — |
| Firewall/router | €150-400 | — |
| Cloud backup | — | €5-20 |
| DNS filtering | — | Free-€20 |
| IT support retainer | — | €100-300 |
| Total | €1,100-2,100 | €105-340 |
Getting Started
Don’t try to do everything at once. Here’s the priority order:
- Week 1: Set up NAS with remote access and automatic backup
- Week 2: Deploy VPN for all remote employees
- Week 3: Implement 2FA on all business accounts
- Week 4: Review access control and create offboarding checklist
Each step builds on the previous one, and you can use your business normally throughout.
