Secure Connectivity Made Simple

How Open Systems Managed SASE Addresses Today's Business Challenges

Securely Work from Anywhere

Open Systems SD-WAN functionality eliminates the need for MPLS and our proxy-based security service edge (SSE) eliminates VPN use with zero trust access to resources located anywhere.

Leverage Cloud for Security

Open Systems SSE provides fast, secure access to business applications and the internet without the overhead of VPNs and multi-hop routing to legacy appliances that don’t scale. Security scales with your business and is delivered at internet speed.

Reduce organizational cost and risk

Replacing legacy network and security infrastructure with Open Systems Managed SASE eliminates appliance purchase, installation and maintenance – and costly MPLS and VPN solutions. SASE eliminates user bypass of the VPN and security controls through always-on network access with SSE supplied security – and it minimizes staffing costs.

Networking and cybersecurity leaders are challenged by their organizations to enable fast, secure ability for employees to work from anywhere, securely leverage the cloud to enable business, and reduce organizational cost and risk.

Applications are moving rapidly to the cloud. Fewer legacy applications remain in the data center. And employees work remotely due to travel or remote or hybrid work policies. These business trends make legacy perimeter security, VPNs and MPLS approaches expensive, less effective and obsolete.

Open Systems Managed SASE provides a comprehensive, unified and easy-to-use single vendor SASE solution delivered as a managed service.
