Managed Secure Edge ROI is the measurable financial return an organization achieves by replacing a fragmented legacy network and security stack with a single managed SASE or SSE platform over a defined period. For a typical mid-market company running 10 to 15 locations, the 36-month ROI ranges from 65% to 162%, with a payback period of 8 to 14 months. The savings come from four sources: hardware refresh avoidance, vendor consolidation, connectivity cost reduction, and recovered operational overhead.
When you add up MPLS circuit costs, hardware refresh cycles, multi-vendor licensing renewals, and the staff time required to manage all of it, a typical mid-market company running 12 locations is spending between $1.3 million and $2.1 million over 36 months on a network and security stack that nobody designed. It accumulated. And most of the people responsible for it have never seen that number on one page.
That is the problem this article solves. It walks through what the all-in, 36-month cost of a typical mid-market legacy stack actually looks like, what changes when you consolidate onto a Managed Secure Edge platform, and how to build a model that holds up in a CFO conversation. Not because it is optimistic, but because it is complete.
The Legacy Stack Problem Nobody Talks About
Most mid-market organizations running 8 to 20 locations share the same basic architecture: separate SD-WAN or MPLS circuits, next-generation firewalls at each site, VPN concentrators for remote users, a secure web gateway, maybe a cloud access security broker (CASB), and a handful of point security tools that someone added after an incident. Each one solved a real problem at the time someone bought it. Collectively, they have become something harder to manage than any individual piece ever was.
The compounding costs hide in plain sight.
Hardware refresh cycles for firewalls and VPN concentrators run on 3 to 5 year schedules. In a 10-site environment, those refreshes rarely fall at the same time, which means capital planning stays murky and actual spend consistently runs above what the budget assumed.
Multi-vendor licensing compounds quietly. Separate renewals for SD-WAN, firewall, SWG, endpoint protection, and MFA add up fast. The negotiating leverage you thought you had with each vendor individually disappears when you are not large enough to matter to any of them.
Operational overhead is the number that is almost always missing from the analysis. Managing 5 to 7 distinct security platforms requires someone to stay current on all of them, push updates across all of them, and troubleshoot the integration points between them. In a mid-market IT department with 3 to 6 people, that overhead does not come free. It comes at the cost of everything else those people should be doing.
Cyber insurance premiums now respond directly to your security posture. Carriers penalize fragmented architectures. If you cannot demonstrate centralized visibility and policy enforcement, expect to pay for it at renewal.
None of this means the legacy stack is indefensible. It means the cost of keeping it is higher than most organizations have calculated.
What Does a Legacy Network and Security Stack Actually Cost Over 36 Months?
For a mid-market company with 650 employees and 12 locations, the all-in 36-month cost of a typical legacy stack runs between $1.4 million and $2.2 million. That figure combines MPLS circuit costs, hardware refresh cycles for firewalls and VPN concentrators, multi-vendor licensing across SD-WAN, SWG, CASB, and endpoint tools, and the operational overhead of managing them all. Most organizations have never seen these line items on a single page.
When we start a network assessment with a new client, the first invoice they cannot find is always the same one: the true monthly cost of their MPLS circuits. It is usually split across two or three carriers, buried in separate cost centers, and nobody has added the lines together in years. That single number, once surfaced, tends to reframe the entire budget conversation that follows.
For a concrete reference point, consider a mid-market company with 650 employees, 12 locations, and the architecture described above. The numbers below come from actual mid-market environments, not a vendor composite organization with 50,000 employees.
Hardware and Licensing (Years 1 to 3)
In a 12-site environment, expect 3 to 4 firewall refreshes within the 36-month window at roughly $8,000 to $15,000 per appliance including licensing. This is consistent with list pricing for mid-market platforms from Cisco Meraki MX, Fortinet FortiGate, and Palo Alto Networks PA-400 series. Add VPN concentrator maintenance, annual SWG and CASB renewals, and SD-WAN licensing across all sites. Conservative total across 36 months: $280,000 to $380,000.
MPLS and Connectivity Costs
MPLS circuits for 12 locations, even at modest bandwidth, typically run $1,800 to $3,500 per site per month depending on geography. Over 36 months at the midpoint: $900,000 to $1.5M. This is the number that stops most people cold when they see it isolated from everything else.
Operational Overhead
A senior network security engineer in most mid-market markets carries $110,000 to $140,000 in fully loaded compensation. If that role spends 30 to 40 percent of its time on platform management, vendor coordination, and policy maintenance across a fragmented stack, which is conservative for a 12-site environment, you are allocating $130,000 to $170,000 over 36 months to overhead that a consolidated managed platform largely eliminates.
Breach and Incident Exposure
According to IBM’s 2024 Cost of a Data Breach Report, the global average cost of a data breach is $4.88 million, with organizations taking an average of 194 days to identify a breach and another 64 days to contain it. That is 258 days of exposure before remediation is complete. For mid-market organizations without 24/7 monitoring, cyber insurance premiums increasingly reflect that detection gap. According to Marsh’s 2024 Global Insurance Market Index, underwriters are actively rewarding organizations that demonstrate stronger controls at renewal, and 75% of insurers now assess network segmentation posture during underwriting. For a mid-market organization paying $120,000 to $140,000 annually in cyber coverage, a 15 to 20 percent improvement at renewal produces $18,000 to $28,000 in annual savings.
36-month status quo total (breach scenario excluded): $1.4M to $2.2M.
Most IT leaders look at that total and immediately start recalculating next year’s budget request. Before that conversation happens, two reference points tend to sharpen the thinking: IT budget benchmarks by industry shows what peers are actually spending on network and security infrastructure, and IT budget planning by sector walks through how organizations align those costs to business priorities before the next planning cycle.

What Changes in Year 1 with Managed Secure Edge
Managed Secure Edge consolidates the separate SD-WAN, firewall, SWG, ZTNA, and cloud security functions onto a single-vendor SSE/SASE platform delivering FWaaS, SWG, ZTNA, and CASB from a shared policy engine and wraps continuous SOC monitoring with SIEM-correlated alerting and defined mean time to respond (MTTR) SLAs around it. Leading platforms in this category include Zscaler Zero Trust Exchange, Netskope Intelligent SSE, and Palo Alto Networks Prisma SASE, all deployed here as a managed service rather than a self-operated product. The managed operations layer is what separates this from a self-managed deployment, and it is where most of the operational ROI lives.
Year 1 looks different from Year 2 and Year 3. Being honest about that difference matters.
Platform and Service Fees
Platform and service fees replace the fragmented vendor stack. Based on Meriplex’s assessment work with mid-market clients, per-user SASE licensing runs $15 to $40 per user per month depending on the security tier, vendor, and bandwidth requirements. For a 650-person environment, that puts platform licensing at $9,750 to $26,000 per month before managed service fees for 24/7 SOC operations, vendor management, and engineering support are added on top. The combined total varies enough by environment that a current quote is the only number worth committing to. That figure looks significant in isolation. Next to the status quo total above, it is the more interesting option.
Transition Costs
Transition costs in Year 1 include circuit migration from MPLS to broadband or direct internet access (DIA) underlays, policy configuration in the new platform, and the overlap period where both environments run simultaneously. Based on Meriplex’s deployment experience with 12-site mid-market environments, professional services for migration typically run $40,000 to $80,000, with the range driven primarily by legacy VPN complexity and how much informal access control has accumulated in the existing environment over time. That figure covers the managed partner’s work. It does not include internal engineering time, which realistically runs 0.25 to 0.5 FTE for three to four months depending on how cleanly the existing environment is documented. Self-managed migrations run higher in both cost and elapsed time, and carry more dependency mapping risk.
Hardware Refresh Avoidance
Hardware refresh avoidance starts immediately. Any firewall appliance due for refresh in Years 1 through 3 comes off the capital plan. Using the per-appliance cost range established earlier, three to four refreshes across a 12-site environment represent $24,000 to $60,000 in avoided capital spend over the window. Organizations still running standalone VPN concentrators eliminate those refresh costs as well, though most mid-market environments at this scale have already consolidated VPN functionality into their NGFWs rather than running dedicated concentrator hardware. The transition to ZTNA removes the per-user VPN licensing and any remaining appliance costs in either case.
Year 1 net position, accounting for transition costs and platform fees against status quo spending: roughly neutral to modestly positive for most mid-market environments. The savings curve accelerates sharply in Years 2 and 3.
The Savings Curve: Years 2 and 3
This is where the SASE TCO comparison becomes clear. SASE TCO (Total Cost of Ownership) accounts for every cost associated with deploying and operating a secure access service edge architecture over a defined period, including platform fees, transition costs, and the ongoing operational expenses that replace legacy infrastructure spending.
Connectivity Cost Reduction
Moving from MPLS to broadband or direct internet access while maintaining security through a cloud-delivered managed platform typically cuts connectivity costs by 20 to 50 percent, with outcomes depending heavily on geography, available fiber infrastructure at each site, and current contract rates. For a 12-site environment spending $900,000 to $1.5M over 36 months on MPLS, a 30 percent reduction produces $270,000 to $450,000 in savings across the three-year window. Organizations in dense urban markets with strong fiber availability at each site can reach the higher end of that range. Those with sites in secondary or rural markets should model conservatively until carrier quotes are in hand.
Vendor Consolidation
Vendor consolidation eliminates 3 to 5 separate security tool renewals. Based on Meriplex’s assessment work with mid-market clients, organizations typically recover $45,000 to $90,000 annually in licensing fees after consolidation, which is $90,000 to $180,000 over Years 2 and 3. This direction is consistent with where the market is heading: according to Gartner’s 2022 Strategic Roadmap for SASE Convergence, 65% of enterprises were projected to consolidate individual SASE components into one or two explicitly partnered vendors by 2025, up from 15% in 2021. Organizations moving now are doing so ahead of a vendor pricing environment that will only get less favorable for holdouts.
Operational Overhead Recovery
Operational overhead recovery shows up in productivity rather than invoices, but it is quantifiable. Based on Meriplex’s assessment work with mid-market clients, consolidating onto a managed platform typically recaptures 30 to 40 percent of a senior engineer’s time, hours previously consumed by managing five or more discrete platforms, coordinating separate vendor escalations for FortiOS, PAN-OS, or Meraki firmware updates, and maintaining manually configured firewall rule sets across 12 sites. Using the compensation range established earlier in this model, that recaptured time represents $65,000 to $110,000 in recovered labor value over Years 2 and 3, time that moves from platform maintenance to architecture work and the projects that sat on hold for years.
Cyber Insurance Impact
Organizations that implement managed secure edge with documented 24/7 SOC monitoring, centralized policy enforcement aligned to NIST SP 800-207 zero trust principles, and verifiable ZTNA replacing legacy VPN report meaningful premium reductions at renewal. CIS Controls v8 alignment is becoming a formal underwriting input across the market: the Center for Internet Security and CyberAcuView, a consortium backed by AIG, Beazley, Chubb, The Hartford, and Travelers, have formally mapped CIS Controls to cyber insurance underwriting requirements — a standard that carriers increasingly reference when assessing risk posture.
The true cost of a legacy network and security stack is not on one invoice. It is distributed across hardware refresh cycles, carrier contracts, licensing renewals, and staff time. Most mid-market organizations have never added those lines together.
The 36-Month ROI Summary
Status Quo: What You Are Already Spending
| Cost Category | 36-Month Total |
|---|---|
| Hardware refresh and licensing | $280K to $380K |
| MPLS connectivity (12 sites) | $900K to $1.5M |
| Operational overhead | $130K to $170K |
| Cyber insurance premium delta | $54K to $84K |
| Status quo total (breach excluded) | $1.35M to $2.1M |
What Changes: Documented Savings Over 36 Months
| Savings Category | 36-Month Range | Primary Driver |
|---|---|---|
| MPLS to DIA connectivity | $270K to $450K | 30% reduction on $900K to $1.5M |
| Vendor licensing consolidation | $90K to $180K | 3 to 5 tool renewals eliminated |
| Operational overhead recovery | $65K to $110K | 30 to 40% of senior engineer time |
| Hardware refresh avoidance | $24K to $60K | Firewalls off the capital plan |
| Total documented savings | $449K to $800K |
The connectivity savings line is the most significant and the most verifiable. It does not depend on vendor pricing, contract timing, or Meriplex service fees. Moving 12 sites off MPLS at a conservative 30 percent reduction produces $270K to $450K in recovered spend that belongs to your organization regardless of which managed platform you choose. The remaining three categories are additive and documentable at the environment level: vendor consolidation, overhead recovery, and hardware avoidance.
What the table above does not capture is breach risk reduction. An organization with 24/7 managed detection, centralized policy enforcement, and ZTNA in place carries a materially different risk profile than one running unmonitored point solutions The ROI of managed IT services case does not depend on a breach scenario. It gets stronger when you include one. It gets stronger when you include one.

What Is the Difference Between Managed Secure Edge and Self-Managed SASE?
Self-managed SASE means your team deploys and operates the platform: configuring policies, monitoring alerts, managing vendor support, and pushing firmware updates. Managed Secure Edge means a partner handles all of that under defined SLAs, wrapping 24/7 SOC operations around the same technology. The operational overhead savings in the table above, $65K to $110K over Years 2 and 3, require managed delivery to realize. A self-managed deployment retains that overhead cost rather than recovering it.
Buying a SASE platform and operating it correctly are two different problems, and the savings model above depends on solving both.
Every major network security vendor now sells a SASE or SSE platform. Deploying one still requires someone to own policy configuration in the platform management console, monitor SIEM-correlated alerts, manage vendor escalations through support portals, push FortiOS or PAN-OS firmware updates on cycle, and tune detection rules as your environment changes. For most mid-market IT teams, that is the same operational overhead problem they had before, now consolidated into one platform rather than seven, but still requiring dedicated expertise to run correctly.
Managed Secure Edge means the platform, the SOC operations, and the engineering expertise arrive as one service. The managed SD-WAN layer handles underlay connectivity. The managed security layer handles continuous monitoring, detection, and defined-SLA response. Vendor relationship management, including license renewals, support escalations, and platform roadmap tracking, happens on your behalf. The overhead savings in the model require that delivery model. The technology alone does not produce them.
Buying a SASE platform and operating it correctly are two different problems. The technology consolidates the tools. Managed delivery consolidates the expertise, the operations, and the accountability.
What Additional Savings Does Managed Secure Edge Produce Beyond the Core TCO Model?
Beyond the four savings categories in the table, three areas produce material value that is harder to quantify without knowing your environment: faster breach detection (IBM 2024 data shows organizations with security automation identify and contain breaches 108 days faster), compliance overhead reduction through centralized logging and automated control evidence, and site scalability that replaces $12K to $25K per-site physical buildouts with a software-defined policy push.
The model above is conservative. Here is what it leaves out.
Faster Incident Response
According to IBM’s 2024 Cost of a Data Breach Report, organizations with high levels of security AI and automation identified and contained breaches 108 days faster than those without. For a managed SOC monitoring your environment around the clock with SIEM-correlated alerting, cutting detection from 194 days to hours changes your insurance posture, your regulatory standing under frameworks like HIPAA Security Rule and PCI DSS v4.0, and the probability that an intrusion becomes a reportable event. This holds regardless of whether you have experienced a breach before.
Compliance Overhead Reduction
Consolidated log management replaces separate SIEM feeds from 5 to 7 point tools. Unified policy documentation and automated control evidence collection reduce the labor cost of compliance reporting for SOC 2 Type II, HIPAA Security Rule, PCI DSS v4.0, and CIS Controls v8. Mid-market organizations typically spend substantial time annually on compliance documentation that centralized platform logging and pre-built audit reports can substantially compress.
Scalability Without Capital Expenditure
Adding a location on a legacy stack means appliance procurement, physical installation, circuit provisioning, and manual firewall rule configuration. Typically 6 to 10 weeks and $12K to $25K per site in professional services and hardware. On a managed secure edge platform, a new location requires a software-defined policy push to a zero-touch provisioned edge device. For growing organizations, this is where the 3-year TCO of SASE diverges most sharply from legacy architecture costs.
For most mid-market organizations, the managed secure edge business case does not depend on a breach scenario to justify the investment. The connectivity savings, hardware avoidance, and recovered staff time produce a payback timeline measured in months, not years.
The Bottom Line
The ROI case for Managed Secure Edge does not need a breach to justify itself. Connectivity savings, vendor consolidation, hardware refresh avoidance, and recovered operational capacity produce $449K to $800K in documented savings over 36 months, with a defensible number behind every line item.
What it requires is an honest accounting of what the legacy stack actually costs. Most organizations have never assembled that calculation in full. When they do, the managed secure edge business case stops being a debate about technology and becomes a question of timing.
Platform and managed service fees are real, vary by environment, and belong in the same conversation as the savings above. We build that complete model before anyone looks at a contract.
