"SASE" gets used as if it's a single product category, but the architecture decisions inside it are dramatically different. Single-vendor backbone vs managed multi-vendor. Network-led vs security-led. Cisco-stack vs vendor-neutral. Below is the honest version of which approach wins when.
| Single-vendor SASECato Networks | Managed SASE-aaSAryaka | Co-managed SASE + MDROpen Systems | Cisco StackCisco Umbrella + Meraki | |
|---|---|---|---|---|
| Architecture | Single-vendor, all SASE on one private backbone | Fully managed SASE-as-a-Service on private backbone | Co-managed SASE with integrated MDR overlay | Cisco product portfolio assembled into a SASE shape |
| Best-fit buyer | Mid-market+ replacing MPLS and consolidating point security | CIO/CISO wanting outcome-as-a-service, not platform ops | CISO wanting SASE network + managed detection in one contract | Cisco-standardized organizations modernizing edge security |
| Operational model | Customer-managed via single console; co-managed available | Aryaka manages it — you set policy, they run it | Open Systems runs the network + the SOC, co-manages with you | Customer-managed across multiple Cisco consoles |
| Differentiator | Built-from-scratch single product, not acquired pieces | Network-engineering depth, fully managed model | Mission-critical SASE + 24/7 SOC under one roof | Cisco standardization and Talos threat intelligence |
| Less ideal when… | You're Microsoft-first and E5-licensed (compare to Ontinue posture) | You want hands-on control and platform-level customization | You already have a mature SOC in place | You're trying to escape Cisco lock-in, not deepen it |
Brief Cato if you're consolidating MPLS plus a sprawl of point security products into one SASE platform, and you want a single vendor that built the product from scratch.
Supplier page →Brief Aryaka if you want SASE as an outcome rather than a platform — fully managed network and security delivered by a team that's been in the network-engineering business for decades.
Supplier page →Brief Open Systems if you want SASE + MDR on one contract, co-managed with a vendor that operates a 24/7 SOC and treats the network as part of the detection surface.
Supplier page →Brief Cisco if you're already standardized on Cisco infrastructure and want to extend that stack to SASE rather than introduce a new vendor relationship.
