SASE Providers and Vendors Comparison (2026).
Authoritative evaluation of the leading SASE platforms for UK and global enterprise buyers, scored against security architecture, identity integration, edge footprint and managed service model. Compare BT Managed SASE alongside Palo Alto Prisma, Zscaler, Netskope, Cato Networks, Cloudflare and the wider market.
Independent research from the Netify team. Updated April 2026.
How Netify scores SASE vendors.
Each vendor is evaluated against four pillars: security architecture (ZTNA, SWG, CASB, FWaaS, DLP), edge and PoP coverage, identity integration and managed service model. Findings feed the Netify RFP Builder so buyers can request structured responses from shortlisted vendors.
Security architecture
Native ZTNA, SWG, CASB, FWaaS and DLP coverage assessed against vendor reference architecture, single-pass inspection and policy unification across web, private apps and cloud.
Edge and PoP coverage
Global PoP density, UK and EMEA presence, latency to enterprise hubs and dedicated SASE fabric vs shared cloud-security backbone.
Identity and managed model
Identity provider integration (Entra ID, Okta, Ping), risk-based access, branch deployment patterns, fully-managed vs co-managed vs DIY operating models.
Leading SASE platforms for UK enterprise.
Curated shortlist for procurement teams comparing SASE providers in 2026. Each card summarises positioning, deployment model and where the vendor fits.
Palo Alto Prisma SASE
Single-vendor SASE combining Prisma Access (cloud-delivered security), Prisma SD-WAN and AIOps. Deep security depth from the Palo Alto firewall heritage; strong fit for security-led procurement.
Zscaler Zero Trust Exchange
Cloud-native ZTNA, SWG, CASB and DLP from a global PoP fabric. Strong identity-led access model. Pairs with third-party SD-WAN for full SASE.
Netskope One
Single-pass cloud security platform with deep CASB and DLP capability. Strong fit for data-centric organisations and cloud-heavy estates.
Cato Networks
Single-vendor SASE built on a global private backbone. Converged SD-WAN, ZTNA, SWG and FWaaS in one platform. Strong fit for mid-market and multi-region enterprises.
Cloudflare One
SASE delivered from the Cloudflare global edge. Strong ZTNA and SWG, particularly for organisations already using Cloudflare for performance and DDoS.
Fortinet FortiSASE
SASE delivered from FortiGate cloud and Fortinet PoPs. Tight integration with FortiGate SD-WAN for organisations with an existing Fortinet estate.
Cisco+ Secure Connect
Cisco SASE bringing Umbrella, Duo and Meraki SD-WAN under a single managed service. Strong fit for Meraki-led estates wanting a converged Cisco operating model.
Versa SASE
Unified SASE platform combining Versa SD-WAN, ZTNA and SSE. Strong fit for organisations needing flexibility between on-premises and cloud-delivered policy.
Check Point Harmony SASE
Cloud-delivered SASE with strong ZTNA, SWG and DLP. Fit for security teams already standardised on Check Point Quantum infrastructure.
BT Managed SASE
BT-managed SASE service combining SD-WAN, ZTNA, SWG and CASB into a single managed contract. UK channel route through Netify as a BT Authorised Partner; resell or buy direct.
Common SASE shortlist patterns.
Procurement shortlists tend to cluster around four buying patterns. Each is a sensible starting point for an RFP based on the existing security and network estate.
Security-led estates
- Existing Palo Alto, Zscaler or Check Point footprint
- Security architecture depth and DLP/CASB capability lead the scoring
- SD-WAN treated as a follow-on procurement
- Common shortlist: Palo Alto Prisma, Zscaler, Netskope, Check Point Harmony
Network-led estates
- SD-WAN already in place or being procured in parallel
- Vendor convergence and single-vendor SASE are weighted heavily
- Common shortlist: Cato Networks, Fortinet FortiSASE, Versa, BT Managed SASE on Fortinet or Meraki
Cloud-first estates
- Heavy use of Microsoft 365, Google Workspace and SaaS
- Identity-driven access and CASB depth lead the scoring
- Common shortlist: Zscaler, Netskope, Cloudflare One, Palo Alto Prisma
UK channel and managed estates
- Preference for a UK contract holder, named UK support and a managed service wrapper
- BT Managed SASE shortlisted alongside cloud-native vendors with UK MSP partners
- Common shortlist: BT Managed SASE, Cisco+ Secure Connect, Cato through UK partners

SASE procurement FAQ.
What is SASE?
SASE is the convergence of network connectivity (typically SD-WAN) with cloud-delivered network security (ZTNA, SWG, CASB, FWaaS, DLP) into a single, identity-driven service. Buyers procure SASE either as a single-vendor platform or as a best-of-breed combination of SD-WAN and SSE.
Which SASE vendors should appear on a UK enterprise shortlist?
Common UK enterprise shortlists in 2026 include Palo Alto Prisma, Zscaler, Netskope, Cato Networks, Cloudflare One, Fortinet FortiSASE, BT Managed SASE and Cisco+ Secure Connect. The right shortlist depends on the existing security stack, SD-WAN status, identity provider and managed service preference.
Single-vendor SASE or best-of-breed?
Single-vendor SASE (Cato, Palo Alto Prisma, Fortinet) offers tighter operational unification and simpler licensing. Best-of-breed pairs a leading SSE provider (Zscaler, Netskope) with a leading SD-WAN vendor for maximum capability per layer at the cost of integration effort.
Where does BT Managed SASE fit?
BT Managed SASE is a UK channel route delivering SD-WAN, ZTNA, SWG and CASB as a managed service. Often shortlisted by buyers who want a UK contract holder, named UK support and a single managed wrapper across connectivity and security. Available direct from BT or through Netify as a BT Authorised Partner.
How does Netify rank SASE vendors?
Netify scores vendors against four pillars: security architecture, edge and PoP coverage, identity and access integration, and managed service model. Scoring data feeds the Netify RFP Builder so procurement teams can issue structured RFPs and compare vendor responses head to head.
