This consumption-based pricing scales with usage, making it accessible for smaller organizations while providing enterprise-grade protection capabilities.
Cloud-based solutions like Azure Firewall eliminate hardware refresh cycles and provide automatic updates, but monthly subscription costs accumulate rapidly. Annual expenses range from $4,020 to over $10,000 depending on traffic volume and feature requirements, requiring careful monitoring to avoid budget overruns.
3. Managed Services Bundle Everything for Predictable Monthly Fees
Managed firewall services typically cost $150-$300 monthly for small businesses, bundling software licenses, monitoring, updates, and technical support into predictable operational expenses. This approach eliminates the need for internal security expertise while providing professional-grade protection and incident response capabilities.
For organizations lacking dedicated IT staff, managed services often deliver better value than self-managed solutions. The bundled approach removes the complexity of calculating separate costs for hardware, licensing, maintenance, and personnel while ensuring continuous security coverage.
Security Subscriptions Cost 30-80% of Initial Hardware Price Annually
Annual subscriptions for security services represent the largest ongoing expense for hardware firewalls, typically accounting for 40-50% of total cost of ownership. These mandatory renewals provide threat intelligence, intrusion prevention, web filtering, and antivirus capabilities required for modern network protection.
Threat Protection and Web Filtering Drive Up Ongoing Costs
Hardware firewall vendors structure their pricing around security bundles rather than individual features. The FortiGate 60F requires $500-$950 annually for Enterprise Protection services, while the SonicWall TZ670 demands $600-$1,000 yearly for complete security subscriptions. High-end units like the Palo Alto PA-440 cost $3,000-$5,000 annually for Core Security Bundle access.
These subscriptions aren’t optional add-ons but required components that keep firewalls effective against evolving threats. Without active subscriptions, hardware firewalls lose access to security updates, threat signatures, and technical support, rendering them increasingly vulnerable over time.
Vendor Price Increases Hit Renewals Hard
Maintenance costs for hardware firewalls increase significantly over time as vendors implement price adjustments on existing customers. SonicWall announced 20% increases on Gen 6/6.5 firewall renewal SKUs effective May 2025, while Fortinet users reported substantial renewal price increases in recent years. These unexpected cost escalations can strain IT budgets and force organizations to reconsider their firewall strategies.
Long-term budgeting must account for annual subscription inflation, typically running 5-15% above general market rates. Multi-year contracts can provide some protection against price volatility but require larger upfront commitments that may not suit all organizations.
Personnel and Management Costs Often Exceed Equipment Expenses
The hidden expense of firewall management frequently represents 10-50% of total cost of ownership, varying dramatically between hardware and software solutions. These personnel costs often surprise organizations focusing primarily on equipment and licensing expenses.
Hardware Needs Skilled Network Engineers at $104,500+ Annually
Hardware firewalls require specialized expertise for configuration, policy management, and incident response. Network security engineers command salaries of $104,500-$143,000 annually, with their time split between multiple IT responsibilities. Even part-time firewall management represents a substantial ongoing investment in human resources.
Enterprise-grade hardware firewalls offer centralized management consoles and vendor support that reduce administrative burden compared to software alternatives. However, organizations still need qualified staff to interpret security events, adjust policies, and coordinate with vendors during incidents or upgrades.
Software Solutions Require More Hands-On Configuration Time
Software firewalls demand higher ongoing management investment due to manual configuration requirements and deeper integration with host systems. Open-source solutions like pfSense require continuous monitoring, log analysis, and manual update application that consumes significant IT resources.
Cloud-based software firewalls reduce some management overhead through automatic updates but require expertise in cloud architecture and API integration. Organizations may spend $12,000-$36,000 annually on dedicated IT staff for firewall management, or $500-$2,000 for basic maintenance activities spread across existing personnel.
