The verdict in three sentences
The operating TCO of an enterprise website plays out between 90 EUR/month (managed hosting only) and over 900 EUR/month for a full setup with WAF + CDN + DR + 24/7 monitoring. Over 3 years, the gap between the two approaches often exceeds 27,000 EUR, but full managed drastically reduces incident risk. A CISO must decide based on the site's criticality, not on the headline price alone.
The line-by-line security detail
Security for an enterprise website is not a single line: it is a stack of layers, each with its cost and role. Here are 2026 orders of magnitude.
| Line item | 2026 range | Role |
|---|---|---|
| EU managed hosting | 90 - 380 EUR/month | Servers, updates, availability |
| WAF + CDN | 45 - 200 EUR/month | Attack filtering, caching |
| EV certificate | 160 - 420 EUR/year | Trust, encryption |
| Backups + DR | 35 - 130 EUR/month | RPO/RTO, recovery |
| Annual security audit | 2,800 - 6,500 EUR/year | Pentest, compliance |
| 24/7 monitoring | 55 - 220 EUR/month | Alerts, on-call |
The most often neglected line is the DR plan (disaster recovery). An enterprise site without a tested DR plan is a risk of prolonged downtime during an incident: the insurance easily justifies the 35 to 130 EUR/month invested.
3-year TCO comparison
Two approaches face off: hosting only (economical, higher risk) and full managed (pricier, controlled risk). Here is the 3-year comparison.
| Line item | Hosting only (3 yrs) | Full managed (3 yrs) |
|---|---|---|
| Hosting | 3,240 EUR | 13,680 EUR |
| WAF + CDN | 0 EUR | 7,200 EUR |
| EV certificate | 480 EUR | 1,260 EUR |
| Backups + DR | 1,260 EUR | 4,680 EUR |
| Security audit | 0 EUR | 13,500 EUR |
| 24/7 monitoring | 0 EUR | 7,920 EUR |
| 3-year total | ~4,980 EUR | ~48,240 EUR |
The ~43,000 EUR gap over 3 years is justified once the site carries a reputation or compliance stake. For a simple brochure site, hosting only suffices; for a regulated enterprise, full managed is a risk-management investment.
Calculating the cost of an incident
A security incident or prolonged downtime is expensive: lost traffic, reputational damage, remediation cost. Post-incident remediation (cleanup, restoration, forensic audit) is commonly billed at 8,000 to 25,000 EUR in 2026, not counting lost revenue. That is the figure to weigh against the managed premium.
Mini case study
Sarah, CISO of a 400-employee enterprise in Amsterdam, is evaluating the operating TCO of the corporate site. She compares hosting only (~4,980 EUR over 3 years) and full managed (~48,240 EUR over 3 years). Gap: ~43,260 EUR.

Her risk math: probability of a major incident estimated at 15% over 3 years with hosting only, versus 3% with managed. Average incident cost: 18,000 EUR (remediation + lost revenue). Expected loss: hosting only = 0.15 x 18,000 = 2,700 EUR; managed = 0.03 x 18,000 = 540 EUR. Beyond the pure probabilistic calc, GDPR compliance obligations and reputational criticality settle it: Sarah selects full managed, a rational call for a regulated enterprise.
FAQ
How much does enterprise website hosting cost in 2026?
From 90 to 380 EUR/month for EU managed, depending on required availability. A 99.9% SLA sits toward the top of the range.
Is a WAF essential?
For an exposed enterprise site, yes. At 45-200 EUR/month, it filters most automated attacks and sharply reduces the risk surface.
What is a DR plan and how much does it cost?
A disaster recovery plan guarantees restoration after an incident. Expect 35 to 130 EUR/month: a modest cost against post-incident remediation at 8,000-25,000 EUR.
Is an annual security audit necessary?
For a regulated enterprise, yes. At 2,800-6,500 EUR/year, it detects vulnerabilities before they are exploited and documents compliance.
What is the 3-year TCO for full managed?
Roughly 48,240 EUR over 3 years for a complete setup (hosting, WAF/CDN, DR, audit, 24/7 monitoring), to be weighed against the cost of an incident.
