Leaving Complexity Behind: Open Systems SASE Experience
The case for running SASE as one service instead of a stack of tools.




Why it is worth reading
Data and applications sit in the cloud and on premises, people work from everywhere - and CIOs at midsize enterprises rarely have the resources or skills to secure all of it alone. Even SASE, the answer to the dissolving perimeter, brings its own complexity: multiple services, often from different vendors, run by a team that has to master network, cloud, and security at once.
This white paper makes the case for SASE as a managed experience instead of another product stack: SSE and SD-WAN as a service, operated by the tier-3 engineers who build the platform, with one user-based flat fee covering onboarding, upgrades, and unlimited support. The delivery record behind it: more than 10,000 locations across 184 countries and over 1.5 million users.
What is inside
- The stress and mess of delivering secure accessWhy the CIO's job got harder as security moved from the data center to an edge that is everywhere.
- What is and why SASEThe Gartner-coined model - and an honest look at the complexity it adds when assembled from multiple vendors.
- Leaving complexity behindSASE Experience as a service: daily management and monitoring offloaded to the vendor's own support and development team.
- A better experience with SASEDedicated tier-3 engineers, follow-the-sun support with 2- to 4-hour SLAs, and a flat OPEX fee with no CAPEX.
- Implementing SASE in your environmentWhat the rollout looks like on a unified data platform: define policies once, enforce them everywhere.
While SASE offers many advantages, it is essential to recognize it adds yet another layer of complexity.Who it is for
- CIOs at midsize enterprises without a large network and security team
- IT leaders comparing do-it-yourself SASE with a fully managed service
- Teams tired of coordinating separate vendors for networking and security
