Open Systems delivers Secure Access Service Edge (SASE) and managed detection and response as a combined cloud-based platform, marketed as SASE+ and MDR+ with a "Mission Control" layer of human experts overseeing the technology. The pitch is a single vendor for both secure networking (SD-WAN, secure web gateway, firewall-as-a-service) and the managed security operations layer on top of it, rather than requiring customers to integrate separate networking and security operations vendors themselves.
Founded in 1990 and headquartered in Zurich, Switzerland, Open Systems has been through several ownership changes: it was previously backed by private equity firm EQT before Swiss Post acquired it in a deal that closed in October 2024, adding digital network and security capability to the postal operator’s broader digital services push. In 2023, the company’s Managed XDR business was carved out as an independent company under the Ontinue brand (retained by EQT rather than sold to Swiss Post), leaving Open Systems to focus on its core SASE and MDR services. The company has roughly 260 employees across offices in Zurich, Bern, Düsseldorf, and San Francisco.
Open Systems has repeatedly appeared in Gartner’s Market Guide for Managed Security Services and Market Guide for Managed Detection and Response Services, and was named among SASE-capable vendors in Gartner’s SD-WAN best-practices research — real analyst-driven recognition rather than a vendor-run award. Its ownership by Swiss Post, a large postal and logistics operator, is a notable structural fact for prospective customers evaluating long-term strategic focus, though the company states it continues to operate as a standalone cybersecurity business.
Innovation Matrix Assessment
A 260-person company with a 30+ year history has continued to iterate its SASE+ and MDR+ offerings and integrate a Mission Control layer, a steady but not especially fast pace typical of a mature managed services provider mid-ownership-transition.
Combining SD-WAN, secure web gateway, firewall-as-a-service, and managed detection and response into one operated platform removes real integration burden for customers who would otherwise stitch together separate networking and SOC vendors.
Changed ownership twice in recent years (EQT private equity, then a October 2024 acquisition by Swiss Post) and spun off its Managed XDR unit as Ontinue in 2023; the acquisition by a large, stable acquirer signals continuity, but the repeated ownership churn makes long-term strategic momentum harder to read than a straightforward growth story.
SASE and MDR are now mainstream, well-established categories; Open Systems is a long-tenured incumbent executing a proven combined-platform model rather than introducing a disruptive new approach.
Repeated inclusion in Gartner's Market Guide for Managed Security Services and Market Guide for MDR Services, plus recognition in Gartner's SD-WAN best-practices research as a full-function SASE vendor, is independent analyst validation rather than a self-reported claim.
Combined SASE and managed detection and response remains directly relevant to enterprises consolidating vendors, though the category is crowded with well-funded competitors and Open Systems' new ownership under a postal/logistics parent raises a question of long-term strategic investment priority.
Why CISOs Should Care
Offers a single-vendor combination of SASE networking and managed detection and response, backed by repeated independent Gartner market guide recognition, for organizations wanting to consolidate secure networking and security operations.
What Makes It Different
Pairs a 30+ year-old SASE/secure networking pedigree with an operated MDR+ service under one roof, rather than requiring customers to separately source networking and security operations vendors.
The Matrix Verdict
53/100 — INCREMENTAL INNOVATOR
A credible, analyst-recognized SASE and MDR incumbent now backed by Swiss Post's balance sheet; solid execution of an established model, with the ownership transition worth watching for long-term strategic focus.
Editorial Note: Claims vs. Verified Findings
The Swiss Post acquisition (closed October 2024), prior EQT ownership, the Ontinue MXDR carve-out, and Gartner market guide inclusions are independently reported by press coverage and Gartner's own published research; specific performance and customer-satisfaction claims tied to Gartner Peer Insights ratings are aggregated third-party reviews rather than Open Systems' own marketing copy.
