To Open Systems

Market trends and drivers

The investment in Open Systems provides access to the rapidly growing Secure SD-WAN as-a-service market at an inflection point, benefitting from strong secular growth drivers: i) increased regulations, ii) lack of in-house security IT capabilities, iii) a more complex cyber threat environment, and iv) increased use of mobile devices, force organizations to outsource cyber security tasks.

Open Systems is able to address those challenges best by offering an end-to-end cyber security solution, tailored to the organizations’ individual needs.

Investment potential

EQT Mid Market Europe is excited to support the continued growth of Open Systems across both its existing products and Swiss home market as well as to actively pursue new growth opportunities. Particular focus will be on strengthening the Company’s go-to-market approach and continue its internationalization into Germany and the United States. In addition, it is intended to actively pursue synergistic M&A in a fragmented market.
