Firewall as a Service & DNS Security
Firewall-as-a-Service and DNS security delivered as cloud-native security functions within the broader SASE platform — meaning policy, identity, and traffic-inspection decisions happen consistently across remote users, branch sites, and cloud workloads rather than per-product-stack.

SD-WAN as a Service
Fully managed SD-WAN engagement — design, deployment, ongoing operations, monitoring, change management, troubleshooting, and 24x7 expert support are delivered by Open Systems rather than the customer. The model fits organizations whose multi-site WAN is mission-critical but whose IT teams cannot reasonably staff a dedicated SD-WAN operations practice.
SASE — Secure Access Service Edge
Open Systems SASE converges SD-WAN, Secure Web Gateway, Cloud Access Security Broker, ZTNA, Firewall-as-a-Service, and DNS security into one cloud-delivered platform — with a single management plane and a single operations team rather than separate vendor relationships per security function.
ZTNA — Zero Trust Network Access
Zero Trust Network Access replaces traditional VPN architectures — where a connected user gets broad network access — with identity- and context-aware access to specific applications, evaluated continuously rather than at session start. Delivered as part of the broader SASE platform rather than as a separate product.
Secure Web Gateway & CASB
Cloud-delivered Secure Web Gateway and Cloud Access Security Broker — converged with SD-WAN and ZTNA into one platform rather than separate per-function products. Policy and detection tuning is delivered as a service rather than as a product the customer installs and operates.
