Sourcing Secure Enterprise Edge technology - the right way.
SASE is the most over-marketed category in enterprise security. Every major network and security vendor now claims full SASE convergence. Most are co-billing point solutions under a shared platform brand. Buying the wrong architecture locks you in for five to seven years. Getting it right requires knowing what genuine convergence looks like - and which vendors have actually built it.

Questions We Help You Answer
- ?Is our SASE shortlist selling real convergence or co-billed point solutions?
- ?Should we buy SASE or SSE-only, and how do we make that decision?
- ?How do we evaluate zero trust vendors without getting lost in the philosophy vs. product debate?
- ?What SD-WAN contract terms should we be negotiating that we're probably not?
- ?How do we structure a SASE migration without disrupting the business?
The Challenge
Why Secure Enterprise Edge sourcing is harder than it looks.
Platform claims that don't hold up under scrutiny
Nearly every major vendor claims 'full SASE' or 'complete zero trust.' In practice, most platforms are acquisitions that haven't been natively integrated. The differences only become apparent at scale - after you've signed.
Long contract terms with significant switching costs
SASE and SD-WAN contracts typically run three to five years. The wrong vendor choice at signing becomes a multi-year performance problem with high exit costs. Front-loading the evaluation is worth the investment.
Network and security teams buying separately
SASE requires joint decisions from networking and security. In most enterprises, these teams have different vendor relationships, different evaluation criteria, and different priorities. The result is a split architecture that defeats the purpose.
Migration complexity is systematically underestimated
Vendors present clean migration paths. The reality of legacy firewall dependencies, branch office complexity, and hybrid environments is messier. Understanding migration scope before signing is critical.
Categories We Source
What we help you buy - and how.
SASE
Fully converged platforms delivering networking (SD-WAN) and security (SSE) as a unified cloud-delivered service - covering ZTNA, CASB, SWG, DLP, and WAN optimization in a single architecture.
The Buying Challenge
Only a small number of vendors have achieved genuine convergence. The majority are selling bundled point solutions. Distinguishing real SASE from marketing SASE requires deep technical evaluation that most buying teams aren't resourced to run.
How Stackcurve Helps
We score vendors on genuine platform integration (not bundled billing), evaluate SSE and SD-WAN maturity separately, and shortlist only vendors whose convergence claim holds up at your scale.
Start a SASE engagement →SSE
Security Service Edge - the security stack of SASE: ZTNA, CASB, SWG, and DLP delivered from the cloud, without the SD-WAN component.
The Buying Challenge
SSE-only buyers have more vendor choice but face greater integration complexity. Connecting SSE to existing SD-WAN or WAN infrastructure requires careful architectural planning that vendor demos gloss over.
How Stackcurve Helps
We evaluate SSE vendors on maturity across all four pillars (ZTNA, CASB, SWG, DLP), assess integration complexity with your existing network, and build a migration roadmap before you commit.
Start a SSE engagement →SD-WAN
Software-defined WAN platforms that replace traditional MPLS with dynamic, policy-driven routing - typically bundled with basic security or integrated with an SSE layer.
The Buying Challenge
SD-WAN pricing is opaque, performance claims vary widely by deployment topology, and the vendor landscape has consolidated significantly through acquisition - creating inherited technical debt in several major platforms.
How Stackcurve Helps
We benchmark vendors on performance at your specific topology, identify acquisition-related integration risks, and negotiate contracts that protect you from hidden costs.
Start a SD-WAN engagement →Zero Trust
Zero trust network access and identity-aware proxy solutions that replace VPN-style perimeter access with granular, continuous verification for every user and device.
The Buying Challenge
Zero trust is both a philosophy and a product category, which creates enormous scope for vendor confusion. 'Zero trust' means something different in every vendor deck. Defining your actual requirements before engaging vendors is critical.
How Stackcurve Helps
We start with your access architecture - users, devices, apps, and trust requirements - then shortlist vendors whose ZTNA capability matches your specific use case, not their broadest platform claim.
Start a Zero Trust engagement →Secure Connectivity
Purpose-built secure connectivity platforms for distributed enterprises, branch offices, and remote workers - covering encrypted overlay networks, cloud-native access, and hybrid connectivity.
The Buying Challenge
This category overlaps with SD-WAN, SASE, and VPN replacement. Buyers often over-buy a full platform when a targeted connectivity solution would meet their requirements at lower cost and complexity.
How Stackcurve Helps
We scope your connectivity requirements precisely - branches, remote users, cloud access - and source the right solution tier, whether that's a targeted tool or a full platform.
Start a Secure Connectivity engagement →NaaS
Network-as-a-Service - consumption-based networking delivered from the cloud, covering WAN, LAN, and security in a unified managed service model.
The Buying Challenge
NaaS is an emerging model with high vendor variability. SLA terms, performance guarantees, and handoff between NaaS and enterprise-managed infrastructure require careful contract review.
How Stackcurve Helps
We evaluate NaaS providers on SLA depth, geographic coverage, and integration with your existing managed services - and structure contracts that protect against performance gaps.
