Curated Supplier · SASE + MDR · Co-managed

Open Systems — SASE and MDR on one contract, co-managed with you.

Mission-critical SASE delivered as a co-managed service, with an integrated 24/7 SOC sitting on top of the same network they manage. The pitch is structural: when the SASE provider and the MDR provider are the same team, detection latency drops and root-cause analysis stops being a finger-pointing exercise. Parent company of Ontinue.

What Open Systems actually does.

Open Systems delivers SASE and MDR as one integrated service. The same team that runs your network also detects on it — which collapses the typical "network team vs SOC team vs MDR vendor" coordination tax during incidents. Their managed services include SASE (SD-WAN, SSE, ZTNA) plus the SOC overlay running on the same telemetry. For CISOs who want one contract for both layers, this is the answer.

Capabilities · A short list

Who this fits.

Best Fit

Mid-market+ CISO wanting SASE + MDR in one contract

You want the operational simplification of one vendor running both network and detection — and you understand the structural advantage of integrating them.

Strong Fit

Mission-critical and regulated environments

Healthcare, financial services, critical infrastructure. The mission-critical positioning is real and the SLAs match it.

Mixed Fit

Organizations with mature internal SOC

If you already operate a strong SOC, you're paying for capabilities you don't need. Cato or Aryaka may be a better network-only fit.

Less Likely

SMB or single-tower buyers

Open Systems' scope and pricing assume mid-market+. SMB buyers should brief Field Effect or Cisco Meraki.
