Cost-Benefit Analysis: Cloud Infrastructure and Security Services Pricing

Cost-Benefit Analysis for Cloud Infrastructure and Security Services

When evaluating cloud infrastructure and security services, the math matters. A cost-benefit analysis translates line items like an Azure VPN Gateway at $1,664.40 based on vpngw1 at $138.70 per month or a Tenable vulnerability management subscription at $3,700 for a one-year term into a single framework that supports go/no-go decisions. This article shows how to structure that analysis, what the numbers imply, and where hidden value lives.

Breaking Down the Azure VPN Gateway Cost

The Azure VPN Gateway pricing example—$1,664.40 annualized from a vpngw1 rate of $138.70 per month—is a baseline for network connectivity. That figure reflects the gateway SKU, the number of connections, and the reserved instance or pay-as-you-go model chosen. In a cost-benefit analysis, this line item competes directly against alternatives such as third-party appliances, self-managed open-source tunnels, or higher-tier gateway SKUs that bundle throughput and SLA guarantees.

What Drives the vpngw1 Monthly Price

• Gateway SKU and throughput tier
• Number of site-to-site or point-to-site connections
• Data transfer and reserved capacity commitments
• Region and billing model (hourly vs. monthly)

For a cost-benefit analysis focused on cloud infrastructure, the VPN gateway is rarely the whole story. It is the connective tissue that determines whether remote offices, branch workers, or hybrid workloads can reach on-premises resources securely. The value of that connectivity is what tips the balance.

Tenable Vulnerability Management: The $3,700 Annual Picture

A one-year Tenable vulnerability management subscription at $3,700 covers scanning assets, prioritizing exposures, and tracking remediation across a defined asset scope. Unlike the Azure VPN Gateway, which is a network layer cost, this is a security operations cost. In a cost-benefit analysis, it must be weighed against the cost of breaches, downtime, and compliance failures that effective vulnerability management helps prevent.

Components Inside the Subscription

• Asset discovery and continuous scanning
• Vulnerability prioritization based on exploitability
• Reporting for compliance frameworks such as PCI DSS or SOC 2
• Team licensing and dashboard access tiers

The $3,700 figure scales with the number of assets and the depth of the module set. A cost-benefit analysis should compare that annual spend to the remediation labor it replaces, the reduction in mean time to patch, and the audit readiness it provides.

Structuring the Cost-Benefit Comparison

A rigorous cost-benefit analysis for cloud infrastructure and security services uses a common denominator. The table below maps the two services against the dimensions that matter most in a decision.

Where the Real Value Lives

In a cost-benefit analysis, the direct spend is only part of the picture. The Azure VPN Gateway protects the paths that traffic travels; the Tenable subscription protects the posture of the assets on those paths. A cost-benefit analysis that looks at them in isolation misses the combined value of a network that is both connected and continuously assessed. The strongest business case pairs connectivity with visibility and shows how each service reduces the risk profile of the other.

Making the Go/No-Go Decision

A practical cost-benefit analysis asks three questions: Does the spend prevent a quantifiable loss? Does it reduce operational toil in a way that frees staff for higher-value work? Does it create a platform that can absorb future services without a proportional cost increase? When the Azure VPN Gateway and Tenable subscription are evaluated together, the combined annual outlay of roughly $5,364 buys a connected and continuously monitored environment. Whether that passes the threshold depends on the scale of the organization, the value of the assets protected, and the cost of the alternatives that are being replaced.
