Network Budget: Planning and Defending Your Annual Allocation

Plan and defend the network budget before the Executive Committee: structure the request, prioritize projects, present a data-driven case, and anticipate cuts. A methodology for CIOs. Practical 2026 guide.

Budget structure

Project CAPEX

• Hardware refresh (5-year cycles)
• New projects (DC, cloud, sites)
• Technology migrations (SD-WAN, WiFi 6E)

Recurring OPEX

• Vendor support (SmartNet, FortiCare)
• Licenses (DNA, UTM, SASE)
• Connectivity (FTTH, MPLS, cloud egress)
• Personnel (IT team salaries)
• Consulting / MSP

Compliance / security

• NIS2 / DORA tools
• SIEM + SOC
• Annual penetration test
• Certifications (ISO 27001)

Typical ratios

• IT budget / revenue: 2-5% standard, 8-12% for banking/tech
• Network budget / IT budget: 10-20%
• Security / IT budget: 8-15% (increasing with NIS2)
• Training: 3-5% of the IT budget

Prioritize projects

• Matrix: business impact × effort
• Must-have (compliance, EoL): priority 1
• Should-have (ROI < 18 months): priority 2
• Nice-to-have: priority 3
• Budget split: 60% must-have + 30% should-have + 10% exploration

Defend the budget

• Storytelling: a specific current problem
• Figures: ROI, payback, TCO
• Comparison: industry benchmark
• Risks: quantify the cost of inaction (fines, downtime)
• Phasing: accept a reduced scope if the budget is cut

Anticipate cuts

• Plan A (requested budget)
• Plan B (20% cut): identify projects to postpone
• Plan C (40% cut): essential items only
• Explain the consequences of each scenario
