The Real Cost of VPN Ownership (It's Way More Than You Think)

The Iceberg Under Your VPN Budget

Most IT leaders know what they pay for VPN hardware and licenses. But like an iceberg, the visible costs are a fraction of the total. Let's go layer by layer.

Layer 1: Hardware (The Visible Cost)

VPN concentrators: $10,000-$100,000 per appliance, depending on capacity. You need at least two for redundancy, ideally geographically distributed. Budget: $40,000-$400,000 for a mid-size enterprise.

Refresh cycle: 3-5 years. So divide that by your refresh period for annual cost.

Layer 2: Licensing (The Predictable Cost)

Per-user VPN licenses: $30-$100 per user per year, depending on vendor and features. For 2,000 users: $60,000-$200,000 per year.

This is the line item finance sees. It's also where vendors have the most leverage during renewals.

Layer 3: Infrastructure (The Hidden Cost)

Your VPN concentrators need: - Data center rack space and power (colocation or on-premises) - Redundant internet circuits sized for VPN traffic - Load balancers for VPN failover - Monitoring and alerting infrastructure

Allocate: $20,000-$80,000 per year depending on your hosting model.

Layer 4: Staff Time (The Biggest Cost)

This is where the real money hides. Your network team spends significant time on VPN operations:

• Day-to-day management: 10-20 hours/week
• Client troubleshooting: 5-15 hours/week
• Certificate and key management: 5-10 hours/month
• Capacity planning and upgrades: 40-80 hours/year
• Security patches and firmware updates: 20-40 hours/year
• Vendor management and license renewals: 20-40 hours/year

At a fully loaded network engineer cost of $150,000-$200,000/year, VPN-related labor costs $75,000-$150,000 per year for a mid-size enterprise. Often more.

Layer 5: Lost Productivity (The Invisible Cost)

Every VPN user loses time to VPN friction: - Connection time: 1-2 minutes per session - Reconnection after drops: 30-60 seconds, multiple times per day - Slow application performance: 10-30 minutes of cumulative delay per day - VPN troubleshooting by end users: 5-15 minutes per incident

Conservative estimate: 15-30 minutes of lost productivity per user per day. For 2,000 users at $50/hour average loaded cost: $1.3M-$2.6M per year in lost productivity.

This is the number that makes CFOs do a double-take.

Layer 6: Security Incident Risk (The Catastrophic Cost)

VPN credentials are a top attack vector. The average cost of a data breach involving compromised credentials is $4.5 million (IBM Cost of a Data Breach, 2025). Not every organization will have a breach — but the risk-adjusted annual cost is real.

Even a minor VPN-related incident (compromised credentials, unauthorized access) costs $50,000-$200,000 in investigation, remediation, and response.

The Total Picture

For a 2,000-person company:

The VPN isn't a $200K/year expense. It's a $1.5M+ drag on your business.

The Comparison

Cloudflare Zero Trust for 2,000 users: - Standard tier: $7/user/month = $168K/year - No hardware, minimal staff time, dramatically better productivity

The business case writes itself.
