Zero Trust gets discussed in the press mostly in the context of large enterprise deployments, which leaves smaller businesses without a realistic sense of what it actually costs at their scale. Here’s a grounded breakdown of what drives the cost, and what a reasonable budget range looks like.
Two Separate Cost Buckets: Build vs. Run
The most useful way to think about Zero Trust and SASE cost is as two distinct phases with different cost structures: the Year 1 build (assessment, design, initial deployment) and ongoing run costs (platform licensing, continued management, optimization) from Year 2 onward. Conflating the two leads to either sticker shock at renewal time or an underestimated initial budget.
For small and mid-size businesses, industry estimates for Year 1 build typically fall in the $50,000-$150,000 range, with $30,000-$80,000 annually for ongoing platform licensing and management from Year 2 forward. Where you land in that range depends heavily on organization size, number of applications being brought under ZTNA, and how many of the five SASE components you’re deploying versus phasing in later.
What Drives Build Cost
Assessment and design work — understanding current state and designing the target architecture is advisory time, typically priced as a fixed fee based on organization complexity rather than headcount alone.
Platform licensing (Year 1 portion) — SASE platforms are typically priced per user or per device, so headcount is a direct driver here.
Deployment labor — migrating applications behind ZTNA, configuring policies, and running a phased rollout (pilot group, then wider rings) takes real hours, and rushing this phase is where migrations tend to generate the most support tickets and pushback.
Number of applications in scope — bringing ten applications under Zero Trust access control is a meaningfully smaller project than bringing in eighty, even at the same headcount.
What Drives Ongoing (Run) Cost
Platform subscription — the recurring per-user or per-device licensing fee, which is the largest ongoing line item for most businesses.
Policy management and tuning — access policies aren’t “set once and forget”; they need periodic review as roles, applications, and threats change.
Continued monitoring — whether handled internally or by a managed service, someone needs to actually watch the telemetry a SASE platform generates, not just collect it.
Why We Don’t Quote Full Deployment Cost Upfront
Deployment costs vary significantly by which SASE vendor a business selects — pricing models differ, and the “right” platform for a given business depends on factors that only become clear after a proper assessment. That’s why our engagement structure separates the fixed-fee advisory phases (assessment, architecture design, policy modeling) from deployment, which gets scoped and quoted once a specific platform has been selected. It’s a more honest way to price this than quoting a number before knowing what’s actually being deployed.
A Reasonable Way to Budget This Internally
Rather than trying to nail down an exact figure before a scoping conversation, budget the advisory phase as a fixed, known cost, and treat deployment and ongoing licensing as a range to be refined once a platform is selected — that’s a more accurate planning approach than anchoring to a single number this early.
