15 Critical Questions You Should Ask a SASE Provider Before Deciding

In today’s rapidly evolving security landscape, choosing the right SASE provider can make or break your network security strategy. With vendors rushing to rebrand existing products as “SASE solutions,” distinguishing between genuine innovation and clever marketing has become increasingly difficult. This checklist cuts through the noise, giving you 15 essential questions to evaluate potential SASE providers effectively. Let’s ensure your investment delivers the security, performance, and simplicity your business deserves.

Core Architecture Questions

1. Is the solution truly converged or just integrated?

Many vendors claim to offer comprehensive SASE, but most are simply bundling existing products. True convergence means security and networking functions are built on a unified code base, not connected through APIs or virtual appliances.

Look for providers who can explain their architecture without mentioning “integration between products.” When security and networking components are truly converged, you’ll see better performance, simplified management, and consistent policy enforcement across all functions.

MCK’s solution was built from the ground up as a unified platform, eliminating the performance bottlenecks and management complexity that come with cobbled-together products.

2. What’s the global reach of the provider’s network?

SASE effectiveness depends heavily on the provider’s global infrastructure. You need points of presence (PoPs) strategically located near your users and resources to deliver low-latency connections.

Ask for a map of their global footprint and verify the proximity to your key locations. A strong provider will have dozens of PoPs across major business centers, with redundant connections between them. Equally important is the quality of their backbone – how traffic is routed between these PoPs and whether they own the infrastructure or rely on the public internet.

3. Is the solution truly cloud-native?

There’s a substantial difference between solutions built for the cloud and those adapted from on-premises technology. True cloud-native architecture provides elasticity, automatic scaling, and continuous updates without disruption.

When evaluating providers, ask about their deployment model and update process. Legacy solutions retrofitted for cloud deployment often retain limitations of their original design, impacting performance and flexibility.

Security Capability Questions

4. Which security functions are truly integrated into the platform?

At minimum, a complete SASE solution should include next-generation firewall (NGFW), secure web gateway (SWG), zero trust network access (ZTNA), and cloud access security broker (CASB) capabilities – all within the same platform.

Ask vendors to demonstrate how these functions work together without requiring separate management interfaces or policy configurations. If they’re selling add-ons for core security functions, you’re looking at an integrated bundle, not a converged platform.

5. How does the provider handle threat intelligence?

Effective security depends on timely, accurate threat intelligence. Your SASE provider should maintain a robust threat research team and intelligence network, with automated mechanisms to deploy protections across their entire platform.

Evaluate how quickly they respond to new threats and how this intelligence is incorporated into their security engine. Advanced providers like MCK leverage AI and machine learning to identify novel threats and automatically implement countermeasures before they affect your business.

According to recent studies, organizations with AI-enhanced security detection identify and contain breaches 74% faster than those without such capabilities, reducing the average cost of a breach by nearly $3 million.

6. What are the data protection and privacy capabilities?

As data moves increasingly to the cloud, protection capabilities become crucial. Comprehensive SASE solutions should include data loss prevention (DLP), encryption, and compliance controls for various regulatory requirements.

Examine how granular these controls are and whether they operate consistently across all access methods. MCK’s solution includes built-in protection mechanisms that maintain compliance with industry standards while allowing legitimate business activities to proceed without friction.

With 80% of SMEs experiencing significant data exfiltration events in the past year, integrated DLP capabilities have become a non-negotiable component of modern security solutions.

Networking Performance Questions

7. What SD-WAN capabilities are included?

SD-WAN functionality is a cornerstone of SASE, providing intelligent routing and connectivity optimization. Evaluate whether the provider offers application-aware routing, dynamic path selection, and quality of service controls as native features.

Ask how the solution handles different traffic types, especially latency-sensitive applications like voice and video. Superior SASE solutions automatically identify applications and apply optimal routing policies without manual configuration.

8. How does the solution optimize application performance?

Beyond basic connectivity, SASE should actively improve application performance. This includes techniques like TCP optimization, data compression, and protocol acceleration for critical business applications.

Inquire about specific optimizations for cloud services you rely on, such as Microsoft 365, Salesforce, or custom applications. MCK’s platform includes specialized optimization for major business applications, delivering performance improvements that users immediately notice.

Research shows that businesses implementing SASE solutions typically see a 30-40% improvement in cloud application performance, directly impacting workforce productivity and satisfaction.

9. What are the high availability and resilience features?

Network disruptions can cripple productivity. Robust SASE solutions include self-healing capabilities that automatically reroute traffic during outages, maintaining connections even when underlying networks fail.

Ask for specific resilience metrics and historical uptime statistics. The best providers maintain redundant paths throughout their network and transparently shift traffic without user intervention when problems occur.

Management and Implementation Questions

10. How intuitive is the management interface?

For SMEs with limited IT resources, management simplicity is non-negotiable. Evaluate the user interface for policy creation, monitoring, and troubleshooting.

Request a live demonstration rather than a slideshow, focusing on common management tasks. Can you create and deploy policies without extensive training? Is reporting comprehensive and easily understood? MCK prioritizes intuitive management, allowing even small IT teams to maintain enterprise-grade security posture.

Studies indicate that organizations with centralized security management spend 65% less time on security administration and experience 45% fewer security incidents due to configuration errors.

11. What is the typical implementation timeline and process?

SASE implementation shouldn’t disrupt your business operations. Ask providers for detailed timelines based on businesses similar to yours.

A well-designed solution allows for phased implementation, starting with the most critical sites or applications. MCK’s deployment methodology minimizes business disruption while quickly delivering security and performance benefits, typically achieving full implementation in weeks rather than months.

12. How are updates and new features deployed?

In traditional security models, updates often meant maintenance windows and potential downtime. Modern SASE should deliver continuous updates without service interruption.

Ask how frequently updates occur and what impact they have on performance. Advanced providers deploy updates seamlessly across their global infrastructure, ensuring all customers immediately benefit from security enhancements and new features.

Business and Support Questions

13. What service level agreements (SLAs) does the provider offer?

SLAs reveal a provider’s confidence in their solution. Look beyond uptime guarantees to performance metrics, security response times, and resolution commitments.

Ask about compensation for SLA violations and the process for reporting issues. MCK offers comprehensive SLAs covering both performance and security, with transparent reporting and accountability mechanisms.

14. What does the total cost structure look like?

SASE should simplify your security spending, not complicate it. Request a complete breakdown of costs, including any potential add-ons or usage-based charges.

Be wary of pricing models that start low but escalate with bandwidth or user growth. The most transparent providers offer predictable, all-inclusive pricing that scales reasonably with your business.

Organizations implementing SASE typically report a 20-30% reduction in total cost of ownership compared to maintaining traditional security and networking point solutions.

15. What level of ongoing support is provided?

Even the best technology requires expert support. Evaluate the provider’s support model, including availability, response times, and the expertise level of support personnel.

Ask whether support is handled in-house or outsourced, and what proactive monitoring is included. MCK provides 24/7 support from SASE specialists who understand both the technology and the unique challenges of SMEs.

Making Your Decision

When evaluating potential SASE providers, create a simple scoring system based on these 15 questions, weighting factors according to your specific priorities. Consider these three approaches:

1. Weighted scoring: Assign importance values to each question based on your business needs, then rate each provider accordingly.
2. Red-line requirements: Identify questions that represent non-negotiable requirements, eliminating providers who don’t meet these minimum standards.
3. Total value assessment: Look beyond immediate costs to consider long-term value, including management simplicity, future scalability, and support quality.
