One of the most common factors we see when large enterprises are considering SASE surrounds cost, with the price of each solution often varying based on a variety of factors or differing models.

In this guide we'll cover the total cost of ownership for SASE, how each model or factor affects overall cost and how you can choose the best vendor for your needs by utilising Netify's SASE cost estimator.

What decides the real cost of SASE for a global enterprise?

Whilst there are often headline per-user prices for vendor's solutions, affordability in global enterprise SASE is actually decided by total cost of ownership and delivery model (as well as the implications of any given solution on your enterprise and daily operations).

When assessing SASE cost, we split providers into four main categories: unified single-vendor platforms, enterprise mega-vendors, cloud-platform vendors, and telco or carrier-managed providers.

This split helps to establish cheapest based on your business' actual needs (whether you need external expertise or can rely on internal capability, your network footprint and risk appetite). By using the Netify SASE cost estimator (below), you can quickly and easily get an indicative monthly and three-year figure based on your own user count, site spread and security depth, as well as then being able to turn that into a full RFP (via the Netify RFP builder) and send it off to relevant providers for responses and quotes.

What does "affordable" really mean for global enterprise SASE?

We find that the cheapest sticker price is rarely the cheapest outcome once you actually get a SASE platform up and running (especially when deployed across a global estate), primarily because deployment, integration, internal operating effort, the add-ons (that turn out to be necessary rather than optional) and additional architectural decisions and strategies all come at further costs. This means that, whilst the sticker price is easy to look at, the actual total cost of ownership for SASE is much broader and complex and many other factors, such as consolidating security appliances into a SASE solution to replace multiple licenses, can have a significant impact.

Which cost drivers determine SASE affordability?

There are typically 7 main factors that can affect the cost of SASE:

• Users and Devices: the most common factor that providers price against, where licenses are typically required for each user or device.
• Sites and Regions: covers point of presence coverage and data residency requirements, where a provider with thin PoP coverage in a region you operate in can either add latency or add cost to close the gap.
• Bandwidth requirements: costs based on bandwidth vary with traffic, which can be worth considering for cloud migration projects and seasonal peaks that may have unexpected cost fluctuations.
• Security depth: SSE-only deployments cost less than full SASE including SD-WAN and, as to be expected, any additional security components come at further cost.
• Delivery model: depending on whether you need fully managed, co-managed or DIY delivery, the cost will reflect the level of responsibility that the provider takes on.
• Implementation and Migration costs: dependent on the extent of the network, the discovery, policy migration, identity integration and phased rollout (alongside the retirement of legacy infrastructure) can all be costly, with larger, more complex networks resulting in much higher costs for some providers.
• Miscellaneous (hidden and recurring costs): some features, such as log retention and overage, can be charged additionally, as well as add-ons like professional services, premium support tiers and the contract uplift applied at renewal, all adding to the total cost of ownership.

How does the Netify SASE cost estimator work?

Our cost estimator above has been specifically designed to provide you with an indicative monthly cost band and a three year TCO band, broken down by cost driver. This means that you can evaluate each solution based on your specific needs (user count, number of sites, the regions or continents in scope, your required security depth, delivery model, and preferred contract term), as well as then being able to take that shortlist into the Netify RFP builder to get real, competitive responses from providers matched to your profile and confirm finalised quotes.

Is managed, co-managed or DIY SASE delivery cheaper?

DIY, as per its name, is where the buyer handles everything independently to the vendor, which can be great as it often comes with the lowest licensing cost, though it's worth noting the complexity of many SASE solutions and, in turn, the internal operating cost and skill requirement can demand a team with the capacity to manage policies, monitor traffic and respond to incidents around the clock, therefore making it the model with the highest operational cost.

Offering more control, co-managed delivery is the fast-growing option, where the buyer keeps policy control while the provider runs the underlying infrastructure, typically suiting teams who want more control over the overall strategy without taking on day-to-day operational running, and is often a good middle ground for organisations that have some internal security resource but not enough to run a full 24x7 operation.

Finally, managed delivery (often through a telco or carrier) offers the highest predictability and fastest time to value, with a single accountable party running both networking and security end to end. Managed delivery comes at the highest price point, though this can be offset by removing internal operating cost and risk (particularly the cost of building and staffing a 24x7 NOC and SOC capability from scratch).

How do SASE pricing models differ and where does the risk sit?

Three commercial models dominate SASE pricing, and each carries a meaningfully different affordability risk that's worth understanding before signing rather than after.

Per-user subscription pricing is the most predictable of the three, since cost scales directly with headcount and there isn't a great deal hiding in the mechanics of it. It's also the easiest to forecast and benchmark against other providers. Bandwidth-based pricing can create surprise cost when traffic patterns shift, which is a particular risk during cloud migration projects or around seasonal peaks where usage spikes well beyond a typical baseline, exactly the moments when a business can least afford an unexpected bill. Tiered bundle pricing needs the closest reading of the three (since capability is commonly locked behind higher tiers), with DLP, CASB and DEM in particular often being premium-tier features, meaning the headline entry tier can look genuinely inexpensive right up until a global rollout needs capability that only sits in the tier above.

Across all three models, a handful of cross-cutting risks apply regardless of which one a provider uses: multi-year commitments traded away for a lower headline discount, true-up charges triggered by user growth, and the uplift mechanism applied automatically at renewal. Each of these can move the real cost of a contract well beyond what the original quote suggested, sometimes substantially so.

Which provider category offers the best value for global enterprise?

Provider value at global enterprise scale sits across four distinct categories, and the right one depends on internal capability and footprint rather than any single category being universally cheapest. We'd be wary of anyone telling you otherwise.

Unified single-vendor platforms, covering Cato Networks, Fortinet (FortiSASE), Versa, Check Point (Harmony) and Aryaka, are typically the best fit for converged simplicity and lower operating cost, since networking and security run on one platform from one provider. There's a genuine simplicity dividend here that's easy to underrate until you're the one managing three separate vendor contracts instead of one.

Enterprise mega-vendors, namely Zscaler and Palo Alto Networks (Prisma SASE), offer the deepest feature sets available in the market, though they commonly require more internal resource to run and tend to sit behind the largest contract values, which is the trade-off that comes with that depth.

Cloud-platform vendors, Cloudflare and Netskope, bring strong global edge coverage and predictable entry-level pricing, though the depth of security capability varies by which modules are included, so it's worth checking carefully rather than assuming parity across providers in this category.

Telco and carrier-managed providers, covering BT, Virgin Media O2, Colt, NTT, Verizon, Comcast Business (Masergy) and Globalgig, are typically the strongest fit where a business wants a single accountable managed service running across a genuinely global estate. There's real value in having one party to call when something goes wrong at three in the morning in a timezone your own team isn't awake in.

The right category for any given organisation depends on existing internal capability and the geographic footprint that needs covering, rather than there being one category that's cheapest across the board. The estimator above can help model where each approach might land on cost, and our scored 10 Best Managed SASE Providers guide goes further into provider-level detail within each category.

How do you pressure-test an affordable SASE quote?

A handful of direct questions, asked before signing rather than after, separate a genuinely affordable SASE contract from one that only looks affordable on the first page, and we'd push hard on all of these before committing to any multi-year term.

Ask what's included in the base tier versus what counts as premium for DLP, CASB, advanced threat protection and DEM (since this is the single most common source of cost surprise after go-live), and whether it's almost always avoidable if the right question gets asked upfront. Ask for the three-year total cost of ownership rather than the year-one discounted figure, including implementation and professional services costs rather than licensing alone, because that year-one figure is doing a lot of work to look better than it is.

Ask precisely how bandwidth, user growth and log retention are charged, and what specifically triggers an overage charge. Ask for the point of presence footprint and latency commitments in every region the business operates in (along with how data residency is handled in each), as well as what's genuinely bundled into the managed service versus billed separately, and where SD-WAN sits within the delivery: as a true component of the platform, or as a separate line item, since those two things get priced very differently. Finally, ask for the renewal terms and the specific mechanism used to calculate any uplift, because that's where a lot of contracts quietly get more expensive over time.

How Netify assesses affordability

We've based our assessment on marketplace data gathered across live vendor engagements, the commercial models each provider publishes and the cost-driver framework set out on this page. We hold no pay-to-play arrangement and no vendor sponsors any ranking or recommendation made here.

The estimator's cost bands are the Netify SASE Methodology v2026.1 calibration, not vendor quotes: they exist to frame a realistic range before you go to market, and the RFP process confirms real pricing.

Netify is an independent UK SD-WAN and SASE marketplace, as well as an Authorised Partner of BT and Virgin Media O2. We connect businesses with channel resellers for SD-WAN, SASE, business broadband, leased lines and hosted voice services from the likes of BT, Virgin Media O2, Aryaka, Cato, Colt, Versa, Zscaler, Fortinet, and Meraki.
