Digitalization, Industrie 4.0 and Industrial IoT are raising new challenges because now data increasingly must traverse the boundary separating OT and IT. Typically, deterministic, industrial OT networks are not coupled tightly with enterprise IT networks. This results in gaps in data and device visibility, application assurance, availability, and security. Bridging that divide requires deep expertise in both worlds and knowledge of the respective operational and security requirements. In the IT world, cybersecurity and trustworthy data are top priorities, whereas in the OT world, plant availability and manufacturing output targets are most important.
Siemens and Aruba bridge this divide based on their deep and complementary expertise in OT and IT. By providing integrated networks with tested interoperability and documented in validated reference designs, the two companies help to ensure that integrated OT/IT systems can be installed rapidly with ease, operated more securely, and supported more efficiently.
Klaus Helmrich, Member of the Management Board at Siemens AG, said: "The cooperation between Siemens and Aruba is an important step to complement our industrial networks offering, which is one of the pillars of the Digital Enterprise, with the additional IT offering from Aruba. Customers will benefit from futureproof, integrated communication networks ensuring availability and security."
Keerti Melkote, President and Co-Founder at Aruba, a Hewlett Packard Enterprise company, said: "Working together for nearly three years, Siemens and Aruba have addressed the OT/IT divide thru technology integration, backed by validated reference designs. The resulting solutions are ideal for a variety of industrial applications, and are backed by both Siemens' and Aruba's support teams."
The solutions include wired and wireless networking products and related software that can be implemented via several channels including the companies' extensive partner networks with direct access to their engineering and support experts. Aruba and Siemens can address customer requirements spanning pre-sales consulting and engineering, professional services (including project management, commissioning, factory acceptance testing, and design engineering), managed operations and maintenance services, and after-sales support.
The solutions help ensure network security that spans both the IT and OT worlds; for example, Aruba's 360 Secure Fabric for IT networks can be combined with Siemens' "Defense in Depth" OT security concept. Since customers' security needs vary, especially in older legacy deployments, Aruba and Siemens will also tailor security solutions to address specific customer requirements.
Heineken, one of the biggest brewing companies in the world, relies on an integrated OT/IT solution from Aruba and Siemens for its Heineken Nederland Supply Brewery 's-Hertogenbosch. "To run efficiently and stave off cybersecurity threats we need uniform visibility and security across our OT and IT," said Henk van den Scheun, Manager Engineering. "Working with Siemens and Aruba we have achieved our objective with a solution that went in very smoothly and has been highly reliable ever since."
