Where to Buy Managed SASE Services with Global Coverage

Traditional models built on multi-vendor stacks, regional MPLS contracts and bolt-on security appliances tend to come with greater operational complexity, inconsistent policy enforcement and coverage gaps, therefore the choice to move to SASE has become increasingly popular.

In this article we'll provide you with a structured, vendor-neutral guide to which providers offer managed SASE (with global reach) and how to navigate the procurement process with our question set designed to get you comparable, decision-ready vendor responses.

What Defines Managed SASE with Global Coverage?

SASE services are delivered in three primary models, each with distinct operational responsibilities - we'd recommend understanding the difference between each and their responsibilities prior to any procurement process.

DIY SASE means the organisation contracts directly with a SASE vendor, deploys its own edge hardware or software and operates policy configuration, monitoring and incident response using internal network and security teams.

Co-Managed SASE introduces a shared responsibility model, where an MSP or MSSP handles day-to-day monitoring and first-line response whilst the customer retains control of strategic policies and change operations.

Fully managed SASE moves design, deployment, monitoring and lifecycle management to the provider (with the customer focused on outcomes) high-level policies and governance.

It's worth noting, however, that choosing a deployment model is only part of the consideration for many organisation - for a managed SASE solution to deliver beneficial multi-national capabilities, these organisations should consider which providers meet the following criteria as these can have a significant impact on ROI.

• PoP density and regional distribution - providers must demonstrate sufficient edge locations across EMEA, APAC and the Americas to serve users without backhauling traffic. A minimum threshold of PoPs in each major region should be confirmed, not assumed.
• Private backbone vs public internet transit - Providers operating private Layer 2 or Tier 1 backbones offer more predictable latency and packet delivery than those relying entirely on public internet paths, providing you with a greater guarantee of maintained performance improvements.
• Data residency and sovereignty controls - Traffic inspection and logging must align with your organisations regulatory and jurisdictional requirements (such as GDPR in Europe, data localisation laws in specific APAC markets and sector-specific regimes).
• Regional NOC and SOC capabilities - Local-language support and regional escalation paths can be critical elements for effective incident response, particularly outside standard business hours.
• Latency SLAs - Leading providers commit to less than 50 ms latency between the user and the nearest PoP in major regions - this should therefore be a contractual commitment (not a marketing estimate) and, even better still, should be backed by significant compensation in the event of failure to meet agreements..
• Compliance certifications - If you're in a regulated industry, ensuring compliance with ISO 27001, SOC 2, PCI DSS, HIPAA, NHS DSPT or GDPR are all required to be demonstrable per hosting region, with audit evidence available on request.

Managed SASE Providers with Global Coverage

To help get you started with procurement, we've identified the primary providers capable of delivering managed SASE across a wide range of international territories, each with documented global infrastructure or backbone presence.

The providers above fall into three broad categories, each with a different approach to backbone ownership, SASE stack design and how much of the operational burden they take on (understanding the distinction will help you narrow your shortlist before issuing an RFI). Should you wish to read more about SASE vendors, we'd recommend the below article where we've gone into detail on each one.

However, we've found that one of the best ways to quickly categorise vendors is how they offer their coverage - often falling into one of global network providers, cloud-native SASE platforms or system integrators/managed security service providers.

Managed SASE Requirements Checklist

Before engaging with providers though, we'd strongly recommend that IT decision makers document a structured requirements set and the associated questions around them - undefined requirements produce incomparable proposals and can slow down your procurement process massively.

We've curated the checklist below to cover what we believe to be the eight most important categories that consistently determine whether a managed SASE solution is viable for a given organisation.

The checklist above is designed to be taken directly into a procurement process - if any category is left undefined before you approach vendors, this may lend itself to proposals that are difficult to compare.

How to Buy Managed SASE - The RFI Process

Once you've created your Managed SASE Requirements Checklist (see the above section), rather than sending this as an ad-hoc questionnaire to a short list of vendors, we'd advise that you utilise a structured RFI process, as this will enable you to garner a broader and more objective market comparison. That's why we've built the Netify SASE RFI Builder, which offers a free way to achieve this far more quickly than traditional methods.

• Step 1: Define requirements: Use the checklist in Section 4 to document site locations, remote user counts, target regions, latency expectations, compliance obligations, preferred security functions (ZTNA, SWG, CASB, FWaaS) and internal operating model.
• Step 2: Generate an RFI: We'd strongly recommend that you use the Netify SASE RFI Builder - it's the simplest way to generate an RFI. The builder applies AI-assisted question generation across 12 procurement categories, including company credentials, SD-WAN capabilities, SASE security features, SLAs, compliance and implementation methodology and you'll instantly get a structured RFI tailored to your specific needs, all of which is assembled in minutes (rather than weeks with other methods).
• Step 3: Publish to the Netify marketplace: Once you submit it, the RFI is then distributed to more than 30 curated vendors and managed service providers with UK, North American and multinational coverage, saving you the task of researching vendors and individually sending them your requirements.
• Step 4: Receive capability statements: Providers respond with structured answers mapped directly to requirement categories, enabling direct comparison of their responses, such as their PoP coverage, managed service models, compliance posture and commercial terms.
• Step 5: Shortlist and evaluate: Use Netify's scoring framework to rank providers, request demonstrations and proofs of concept and gather detailed global connectivity pricing through the same workspace.

87 Vendor-Neutral Questions for SASE Procurement | Netify

To assist with prourement, this article provides the 87 vendor-neutral questions across 12 different categories, all of which are based on real SASE deployments.

Why Netify for SASE RFIs

Most managed SASE procurement processes start the same way, a shortlist of familiar vendor names, a set of ad-hoc questions sent out individually and proposals that arrive in different formats and answer different things.

With Netify, our SASE RFI Quick Builder was built specifically to address the structural problem with ad-hoc procurement. As a vendor-neutral marketplace, our focus is helping you to generate a consistent, structured question set across the full range of procurement categories and getting that RFI simultaneously distributed to a curated list of more than 30 vendors and MSPs.

Managed SASE Vendor Selection Criteria

And once vendors have replied with their capabilities, we'd then recommend a weighted scoring model to help with your objective comparison across shortlisted providers and helps align IT, security and procurement stakeholders on a shared evaluation framework.

Why Weighted Over Average Scoring?

Given that every business is different, the features that you'll get the most value from will likely differ from other businesses - therefore placing a weight on the score of each criterion allows you to gain a more accurate picture of how vendor solutions will best benefit your specific use case.

To use this matrix, score each provider from 1 to 10 for every criterion based on RFI responses and supporting documentation, then multiply each score by the corresponding weight and sum the results to produce a weighted total out of 10. This approach best supports structured debate between stakeholders, provides a documented basis for down-selection decisions.

Conclusion

Managed SASE with global coverage can be sourced from global network service providers, cloud-native SASE platforms and systems integrators, each offering different balances of backbone ownership, platform integration and operational delivery model.

The key aspect of procurement is not necessarily the vendor selection process, but the process(es) you take to evaluate your business' specific needs and how solutions can support your potential growth. A structured RFI produces comparable responses, reduces procurement timelines and surfaces requirements that ad-hoc conversations miss and that's why we'd strongly advise businesses utilise the Netify RFI Builder, which provides a vendor-neutral mechanism to define requirements, distribute to a curated pool of more than 30 global providers and evaluate responses within a single workspace.
