The best SASE tools in 2026: Prisma Access, Netskope One, Cato SASE, FortiSASE, Versa, Sangfor Access Secure, and iboss compared by backbone, SSE features, and fit.
Palo Alto Networks Prisma Access is the enterprise default: SSE plus SD-WAN on a hyperscale backbone with a 99.999% uptime SLA. Cato SASE is the pick when you want networking and security from one vendor on one private backbone, including the SD-WAN hardware. Netskope One Converged Access fits organizations that want the deepest SaaS and cloud app risk context in access policy.
Secure Access Service Edge combines the network (SD-WAN, a global backbone) and the security stack (secure web gateway, CASB, zero trust access, firewall as a service) into one cloud service. The promise is that a user in a branch, at home, or on the road gets the same security and the same performance without the traffic hairpinning through a data center.
The products below are all genuine SASE offerings with both halves. They differ on whose backbone you ride, how much of the networking comes from the same vendor, how deep the app and data controls go, and what you already own. For most buyers the decision comes down to the existing firewall and network vendor, the size of the branch estate, and how much the security team cares about SaaS data controls versus the network team caring about WAN economics.

Best for: Enterprises that want the full security stack on a hyperscale backbone
Prisma Access is Palo Alto Networks' cloud-delivered SASE. It unifies Security Service Edge and SD-WAN, with AI-powered inline threat prevention fed by Palo Alto's threat intelligence, zero trust network access, and application acceleration for SaaS and web apps. It runs on a hyperscale backbone with a 99.999% uptime SLA.
Management is through Strata Cloud Manager, the same console as the firewalls, and it pairs with Prisma SD-WAN and Prisma Browser. That continuity is the main argument for existing Palo Alto customers: one policy model from the data center firewall to the remote user.
It fits SMB through enterprise in our data, but the economics and the operational model favor organizations that already run Palo Alto or have the team to adopt its policy framework. Pricing is not published.
Netskope One Converged Access
Best for: Security teams that want app and data risk context in every access decision
Netskope One Converged Access combines SD-WAN with the Netskope SSE stack: secure web gateway, CASB, and zero trust network access, delivered over the NewEdge global network. It covers remote users, branches, IoT and OT devices, and multi-cloud environments on AWS, Azure, and Google Cloud.
The differentiator is the Zero Trust Engine, which evaluates nine layers of trust including user identity, device posture, and application risk, with risk ratings for more than 85,000 applications. Policies adapt to user risk, device risk across millions of devices, and app risk. Zero-touch provisioning, AI-driven automation, and digital experience management cover the network side, and IoT and OT discovery and classification extend visibility beyond laptops.
Netskope came to SASE from CASB, and it shows: the SaaS and data controls are the strongest part. Organizations whose pain is the WAN itself should weigh Cato and Versa as well.
Cato Networks Cato SASE
Best for: Organizations replacing MPLS and branch firewalls with one service
Cato SASE connects locations, users, applications, and clouds through a global private backbone of points of presence in regional data centers, interconnected across multiple carriers. Connectivity is encrypted and SLA-backed, with traffic optimization and acceleration for voice, video, and legacy applications.
The networking half is concrete: Cato Socket appliances provide SD-WAN with active-active link aggregation and dynamic path selection across fiber, cable, and other last-mile links. Security services on the backbone include firewall as a service, secure web gateway, and intrusion prevention. Endpoint clients cover Windows, Mac, iOS, Android, and Linux, and digital experience monitoring uses real-time and synthetic probing.
Cato is built for mid-market and enterprise organizations that want one vendor for the WAN and its security. Our data lists no named integrations, which reflects the all-in-one model; check how it coexists with any security tools you intend to keep.
Fortinet FortiSASE
Best for: Fortinet shops extending FortiGate policy to remote users
FortiSASE combines SSE with secure SD-WAN on a single operating system and a single client agent. The security components are broad: secure web gateway, zero trust network access, CASB, firewall as a service, remote browser isolation, SaaS security posture management, and end-to-end digital experience monitoring.
It integrates with FortiAP, FortiSwitch, and FortiExtender on the LAN side and with Google Cloud and AWS on the cloud side, so an organization already standardized on Fortinet gets the same FortiOS policy model from the access point to the cloud edge.
That is the core case for it. FortiSASE fits SMB through enterprise and is usually the path of least resistance for existing FortiGate customers; organizations on another firewall vendor should compare it on the SSE features rather than on the ecosystem.

Best for: Network teams that need carrier-grade routing with security built in
Versa Secure SD-WAN is networking first. It pairs carrier-grade routing protocols with SD-WAN, supports IPv4 and IPv6, and offers multi-tenancy with separate data, control, and management planes, which is why it is common among service providers and large enterprises consolidating many networks. Zero-touch provisioning speeds branch rollouts.
Security is native to the platform rather than bolted on: encrypted overlays, a next-generation firewall with IDS and IPS, advanced threat protection with sandboxing, and user and entity behavior analytics. Application-aware QoS, performance monitoring, and NetFlow and IPFIX telemetry serve the network operations team.
Versa fits mid-market and enterprise. It is the product for organizations whose SASE project is led by the network team and whose priority is WAN performance and control, with security as a strong second. Our data lists no named integrations.
Sangfor Access Secure
Best for: Distributed workforces in Asia-Pacific and cross-border networks
Sangfor Access Secure combines SD-WAN with network security services for distributed workforces. Zero trust network access comes through Sangfor Zero Trust Guard, which gives granular access to private applications in public clouds or data centers with continuous verification of identity and device health.
A notable feature is the all-in-one agent for mobile users that combines zero trust access with EDR, so a single client handles both access and endpoint protection. The security stack includes AI-driven malware detection through Sangfor Engine Zero, a next-generation firewall, intrusion prevention, and a secure web gateway, and the platform offers cross-border traffic acceleration.
It fits SMB through enterprise and maps to Detect and Respond functions as well as Protect in our data. The cross-border acceleration and the agent design make it a strong regional candidate; confirm points of presence for your user locations.
iboss AI-Powered SASE Platform
Best for: Organizations that want DLP and AI tool controls inside the SASE layer
iboss AI-Powered SASE Platform ingests signals across endpoint, network, and content layers and packages six modules: AI-powered CASB with shadow IT discovery, advanced DLP, secure web gateway with full session telemetry, zero trust access with identity and device posture checks, remote browser isolation, and zero trust SD-WAN for branches.
Two things stand out. The DLP is real-time with sensitive data pattern detection, and the platform includes AI chat monitoring and access controls for enterprise AI tools, which is a current need that older SASE stacks handle poorly. Automated incident creation and reporting feed the SOC.
iboss fits SMB through enterprise and is cloud-delivered. Our data lists no named integrations. It is a strong fit where the security team's concern is data leaving through browsers and AI assistants, less so where the driver is a large branch WAN.
How to Choose the Right Tool
SASE buying decisions go wrong when the network team and the security team evaluate separately. Put both in the room, list the existing vendors, and decide what the project is really replacing.
Start with what you own. Existing Palo Alto, Fortinet, or Netskope estates make their SASE the lowest-friction path; compare the others against that baseline.
Decide who leads. A WAN replacement project points at Cato or Versa; a security consolidation project points at Prisma Access, Netskope, or iboss.
Map user locations against points of presence and ask for latency numbers from those regions, not global averages. Regional strength varies (Sangfor in Asia-Pacific, for example).
List the SSE features you will actually enforce in year one: SWG, CASB, ZTNA, DLP, RBI, SSPM. Buy the product that does those well, not the one with the longest list.
Check how many agents end up on the laptop. One client for access, web security, and endpoint protection (Sangfor, FortiSASE) is simpler to operate than three.
Ask how AI tools and browser data leakage are controlled. iboss and Netskope address this directly.
Insist on a pilot with a real branch and a real remote cohort, measuring application experience with the vendor's DEM before cutover.

Side-by-side features, integrations, and ratings for Secure Access Service Edge tools.
Existing firewall and network vendors decide most SASE shortlists: Palo Alto customers look at Prisma Access first, Fortinet customers at FortiSASE. If the project is a WAN replacement, Cato and Versa are the natural comparison. If the project is about SaaS, data, and AI tool control, Netskope and iboss lead. Pilot with real branches and real remote users, and measure experience before you measure savings.
Frequently Asked Questions
What is the difference between SASE and SSE?
SSE is the security half: secure web gateway, CASB, zero trust network access, and related controls delivered from the cloud. SASE adds the networking half, SD-WAN and a backbone. All seven products here include both.
Do I need to replace my firewalls to adopt SASE?
Not immediately. Prisma Access and FortiSASE extend existing Palo Alto and Fortinet policy to remote users and branches. Cato and Versa are more often chosen when the plan is to retire branch firewalls and MPLS.
Which SASE products run on their own private backbone?
Cato SASE runs on its own global private backbone with SLA-backed connectivity. Prisma Access runs on a hyperscale backbone with a 99.999% SLA, and Netskope runs on its NewEdge network.
Does SASE replace VPN?
Zero trust network access inside SASE replaces VPN for application access. Prisma Access, Netskope, FortiSASE, Sangfor, and iboss all include ZTNA.
How is SASE priced?
Per user per year for the SSE side, plus per-site or bandwidth-based pricing for SD-WAN and backbone. None of the vendors here publish enterprise list prices.
Can SASE control what employees paste into AI chat tools?
Some can. iboss lists AI chat monitoring and access controls, and Netskope's CASB and DLP cover AI applications as part of its app risk catalog.
