Security budgets don’t always increase at the same pace as cyber risks. That makes the investment case especially important, especially when it comes to domain name system (DNS) security.
Organizations can strengthen their position by connecting DNS controls to measurable business outcomes, such as reduced downtime exposure, more efficient operations, stronger incident readiness, and clearer financial risk modeling.
For deeper insights, read CSC’s The ROI of DNS Report: Downtime Risk and Business Impact. Based on a survey of technology leaders, the report covers cost comparisons, annualized loss expectancy, automation opportunities, and DNS’s role in business continuity.
Understanding the budget context for cybersecurity and DNS
Organizations increasingly ask cybersecurity leaders to do more with budgets that only grow incrementally. In last year’s CISO Outlook report, just 7% of technology leaders we surveyed reported a significant budget increase from 2024 to 2025, while 80% reported a moderate increase. That gap points to rising risk of domain-based threats and the need for foundational controls that support uptime, customer trust, and continuity.
For DNS, the budget conversation should begin with role and dependency. DNS isn’t simply a back-office technical function—it also determines how customers, employees, and partners interact with your brand, be it through websites, email, and applications. In tighter budget cycles, the goal isn’t to spend more by default. It’s to allocate security investment where risk reduction, resilience, and business value can be made visible.
The financial impact of DNS: Cost savings and business value
A useful DNS ROI case starts by making cost tangible. For example, let’s say it costs an organization roughly $160,000 annually to have two full-time employees manage DNS internally. That total also includes hardware, software, and bandwidth costs. By comparison, an external DNS service may cost $50,000/year, which produces an estimated savings of $110,000/year!
Organizations should assess downtime in the same practical way. A DNS disruption may affect transactions, productivity, incident response, customer access, and contractual obligations. Direct costs—such as emergency support, remediation, refunds, and service-level agreement (SLA) penalties—are easier to measure. Indirect costs, including regulatory scrutiny, legal exposure, cyber insurance implications, and brand reputation, may be harder to quantify but should still be considered.
This is where the annualized loss expectancy (ALE) method can help. By multiplying single loss expectancy by annual rate of occurrence, organizations can estimate annualized loss expectancy. It doesn’t turn risk into a perfect forecast, but it does translate DNS failure scenarios into business terms.
Operational maturity and automation: Enhancing security resilience
DNS security also supports operational maturity. Our research from CISO Outlook 2025 found that 50% of respondents said they have developed and regularly tested incident response plans, and 50% reported using an AI-based monitoring and enforcement solution. These figures point to a broader shift: Security teams are prioritizing repeatable, scalable approaches that improve visibility and response.
Automation has a practical role in this shift. DNS and domain operations often involve configuration management, monitoring, record updates, threat detection, and incident workflows. Manual processes become harder to govern across large domain portfolios, multiple business units, and complex infrastructure environments. Automation can reduce repetitive work, support consistency, and shorten response times when action is needed.
Automation is also part of managing certificate life cycles. As certificate life cycles shorten under CA/Browser Forum changes through 2029, organizations may need to renew SSL and TLS certificates more frequently, with the report citing a future average of eight renewals per year. Automated renewal workflows can reduce missed expirations and related service interruptions. In budget terms, this is a case for both efficiency and resilience.
Positioning DNS security in the broader cybersecurity strategy
DNS security should be positioned as part of a broader cybersecurity strategy, not as a separate technical project. It’s recommended for each business case to be tailored to each stakeholder group: Executives tend to focus on business continuity and risk exposure; legal teams on compliance and liability; finance on ROI and cost control; and marketing on brand trust and phishing prevention.
That framing is important because DNS security affects more than infrastructure teams. Stronger DNS controls can support cyber risk reduction, incident response, brand protection, and continuity planning. It can also complement other security initiatives, including monitoring, governance, and response readiness.
Conclusion: Building a defensible ROI case
A defensible DNS ROI case connects investment to measurable business value. Cost models, annualized loss expectancy, operational automation, and stakeholder-specific messaging can help security leaders make the case without relying on alarmist language.
For organizations working within tight cybersecurity budgets, DNS security deserves consideration due to its importance to continuity, efficiency, and risk-based prioritization.
