ZTNA pricing & cost comparison: Is a cloud-based model more cost-efficient?

In today’s digital-first business environment, the way organisations secure access to applications and data is evolving rapidly. For many years, traditional VPNs were the default solution for remote connectivity. However, as workforces become more distributed and cloud adoption accelerates, legacy access models are increasingly struggling to meet modern security, performance, and scalability requirements.

This shift has brought Zero Trust Network Access (ZTNA) firmly into focus. Yet for IT leaders, CISOs, and CFOs alike, the discussion is not only about stronger security, it is equally about cost efficiency. The key question remains: is a cloud-based ZTNA model more cost-effective than maintaining traditional access solutions?

This guide explores ZTNA pricing, compares different cost models, and helps organisations understand where long-term value and return on investment truly lie.

Why ZTNA pricing matters for security and IT budgets

When evaluating new security technologies, pricing should never be viewed in isolation. The real consideration is total cost of ownership (TCO), combined with the financial impact of security risk.

Traditional VPNs often appear cost-effective initially, particularly if the infrastructure is already in place. However, this perceived affordability can mask significant long-term costs. VPNs typically provide broad network access, meaning that once a user is connected, they may access more resources than necessary. This increases the risk of lateral movement, ransomware propagation, and costly data breaches.

ZTNA pricing matters because it addresses these hidden expenses:

• Risk mitigation: ZTNA enforces least-privilege access, reducing the financial impact of breaches by limiting exposure.

• Operational efficiency: Faster onboarding of users and applications lowers administrative overhead for IT teams.

• Scalability: Cloud-based ZTNA scales easily with remote and hybrid workforces, avoiding costly infrastructure upgrades.

Built on the principle of “never trust, always verify”, ZTNA continuously validates identity and context before granting access. By preventing lateral movement, it significantly reduces the potential cost of recovery following a security incident.

Common ZTNA pricing models

ZTNA pricing varies depending on architecture and service scope. While vendors differ in their commercial structures, most models fall into the following categories:

• Per-user subscription
  This is the most common approach for cloud-based ZTNA. Organisations pay a monthly or annual fee per user, aligning costs directly with workforce size.

• Per-application pricing
  Some models charge based on the number of applications protected rather than users. This can be cost-effective for organisations with a small number of critical legacy applications.

• Tiered bundles (SASE / SSE)
  Many providers offer ZTNA as part of a broader Secure Access Service Edge (SASE) or Security Service Edge (SSE) package. This consolidates ZTNA with capabilities such as SD-WAN, CASB, and FWaaS into a single commercial model.

• Managed services
  In this model, the provider handles deployment, monitoring, and ongoing operations. While this includes service fees, it significantly reduces internal management overhead.

Each model influences not only cost but also operational complexity and long-term flexibility.

Factors that influence ZTNA pricing

ZTNA pricing can vary widely due to several technical and operational factors:

• Deployment architecture:
  Endpoint-initiated ZTNA requires agents on user devices, offering greater control but increased management effort. Service-initiated, cloud-native ZTNA is often agentless for web applications, enabling faster deployment with reduced overhead.

• Global infrastructure and Points of Presence (PoPs):
  A globally distributed PoP network ensures low-latency access and consistent user experience. However, maintaining this infrastructure is reflected in provider pricing.

• Policy complexity:
  Granular, context-aware policies—based on device posture, location, and time—require more sophisticated processing, which can influence implementation and operational costs.

• Managed versus self-managed models:
  Fully managed services reduce the need for in-house expertise, shifting costs from internal headcount to predictable service fees.

Understanding these variables is essential for accurate cost comparison.

Hidden costs of traditional access models

While legacy systems may seem "paid for," they carry substantial hidden financial burdens that drain IT budgets:

• Hardware refresh cycles: On-premises appliances require periodic, expensive hardware replacements and physical maintenance.

• VPN concentrator upgrades: As remote traffic grows, organisations must constantly upgrade concentrators to prevent performance bottlenecks.

• Security breach costs: The broad network access granted by VPNs increases the likelihood of lateral movement during a breach, leading to massive remediation expenses.

• Increased support tickets: Legacy systems are prone to connectivity issues, overwhelming help desks with troubleshooting requests.

• User productivity loss: Latency and poor "backhauling" of traffic frustrate employees, directly impacting billable hours and output.

• Complex M&A integration: Merging entire networks during acquisitions is costly and slow compared to application-level ZTNA policies.

Cloud-based vs on-prem ZTNA costs

When comparing cloud-based ZTNA with on-premises solutions, the shift from Capital Expenditure (CapEx) to Operational Expenditure (OpEx) is the primary driver.

Cloud-based ZTNA typically uses a subscription model, converting large upfront investments into predictable monthly costs. It scales easily, benefits from global PoPs, and requires minimal maintenance compared to on-premises solutions, which involve higher upfront costs for servers and ongoing expenses for cooling, power, and physical security.

Although ZTNA may involve a higher initial investment, it delivers long-term savings through reduced risk, improved efficiency, and future-ready scalability.

Long-term TCO benefits of cloud-based ZTNA

In the long term, cloud-based models offer clear financial advantages:

• Reduced infrastructure overhead: Service-initiated ZTNA eliminates the need for extensive on-premises hardware and simplifies deployment.

• Improved user experience: Performance-optimised access based on user location directly impacts employee efficiency and output.

• Simplified M&A: ZTNA enables secure resource sharing without merging entire networks, significantly reducing integration costs.

• Lower attack reconnaissance: Applications remain hidden behind outbound-only connections, reducing the cost of defending against scanning and brute-force attacks.

These factors collectively make cloud-based ZTNA more cost-efficient over time.

Best practices for evaluating ZTNA pricing options

To maximise value and control costs, organisations should follow these best practices:

• Define clear objectives: Identify critical applications and user groups to avoid over-licensing.

• Rationalise access: Remove unnecessary permissions during implementation to reduce licensing scope.

• Prioritise high-value assets: Secure the most sensitive resources first for immediate risk reduction.

• Choose unified platforms: SASE-based solutions often reduce costs compared to managing multiple tools.

• Consider managed services: Ideal for teams with limited internal security resources.

A structured evaluation ensures pricing aligns with both security needs and business strategy.

Final thoughts on ZTNA pricing & cost comparison

ZTNA is not simply a replacement for VPNs, it represents a fundamental shift in how access security is designed and delivered. While traditional VPNs may appear cheaper in the short term, their scalability limitations and inherent security risks make them increasingly costly over time.

Cloud-based ZTNA provides granular access control, enhanced compliance, and a scalable foundation for hybrid work. Its cost efficiency stems from reduced risk, lower operational complexity, and the ability to support business growth without legacy constraints.

Organisations that view ZTNA as a strategic investment, rather than a tactical expense, are better positioned for long-term resilience.
