Most networking vendors provide similar levels of performance, but it is the other criteria of ease of management, reliability and total cost of ownership where Allied Telesis really shines. – Vahur Jõesalu, Managing Director at BRS Networks Baltic

HANZA Group is Northern Europe’s most innovative Complete Manufacturing Services (CMS) provider. The company brings together a diverse range of manufacturing technologies and capabilities in its local facilities in order to minimize costs, shorten lead times and make processes more environmentally friendly. Leading companies such as ABB, Epiroc, Getinge, Oerlikon, Saab and Siemens rely on HANZA’s advisory services and production prowess to bring high-quality products to market.

Founded in Sweden in 2008, HANZA is on a growth trajectory aided by both organic expansion and acquisitions. Manufacturing companies based in Finland and Germany are among the most recent acquisitions. Today HANZA Group operates over a dozen plants in Sweden, Germany, Finland, Estonia, Poland, the Czech Republic and China.

Onboarding newly acquired facilities leads to networking challenges

HANZA is developing manufacturing clusters and undertaking the extensive integration of all its facilities. A key element of enabling the plants to operate cohesively is the underlying network. Communications among the different facilities as well as operations within each location are dependent upon a reliable and robust network. This has been a challenge with the legacy networks inherited through the acquisitions.

These legacy networks include disparate equipment and technologies from numerous vendors, making it nearly impossible to have standardized processes for consistent connectivity and network management and maintenance. Some of the factories contained an infrastructure of old cabling and networking equipment. This creates complexity and can lead to higher costs for IT support. What’s more, the legacy networks can’t be properly segmented for security, putting the business at risk of harmful cyber-attacks.

Criteria for a new network

In 2019, HANZA outsourced part of its IT operations to BRS Networks Baltics, where Vahur Jõesalu is the managing director. Jõesalu says his company proposed to build a new centrally managed IT network and operate it as a managed service provider.

BRS Networks established several criteria for the new network. The company planned for site-to-site connectivity to be provided via a VPN infrastructure, with assurances that if a single location goes offline, it doesn’t affect the rest of the network. Due to cost constraints, the networking within each facility would be provided using regular enterprise switches rather than ruggedized industrial quality switches. BRS Networks decided it would deal with environmental conditions in other ways.

Centralized management of the entire network was a top consideration so that every HANZA location could be managed remotely and consistently. In addition, network automation was needed for activities such as configuration backups and firmware updates. Automating many manual tasks can reduce errors and save time.

Allied Telesis beats the competition with its management capabilities

After investigating potential solutions, BRS Networks narrowed its vendor selection to Allied Telesis and two other leading networking companies. “We have experience with all three vendors,” said Jõesalu. “They all make good switches, so we based our decision on overall ease of management, reliability, total cost, and performance.”

The site-to-site VPN network is built using top-tier security vendor’s firewalls, which were already in place in each HANZA facility. BRS Networks made the decision to continue utilizing this existing firewall equipment as a cost-saving measure. Then it became a matter of choosing the internal switches to support local networking within each manufacturing facility.

One of the brands under consideration could be managed via the existing firewalls. However, the number of switches required per location exceeded the firewalls’ capacity to manage them. In essence, using this brand of switches would force replacement of the firewalls with larger devices—thus, defeating the intent to reuse the existing firewalls, and driving up costs.

A second vendor’s switches were ruled out due to stability and performance issues when faced with a high load. While the switches work well in a less demanding environment, they weren’t suitable for HANZA’s enterprise needs.

Allied Telesis was the clear winner for the switched networks inside the facilities based on several characteristics, including outstanding features for network resiliency and centralized management. “In terms of our main selection criteria, we find that most networking vendors provide similar levels of performance, but it is the other criteria of ease of management, reliability and total cost of ownership where Allied Telesis really shines,” says Jõesalu.


We have a relationship with our Allied Telesis counterparts where we can just pick up the phone and call them. With so many other vendors, we’d have to submit a support ticket and wait for a response. Sometimes this can take days. Allied Telesis’ responsiveness helps us serve our customers like HANZA so much better. – Vahur Jõesalu, Managing Director at BRS Networks Baltic

A winning combination: stability, resiliency and easy management

In the new configuration, each HANZA location is controlled internally by multiple network switches. To ensure resiliency and uptime in the network, BRS Networks utilizes Allied Telesis’ Virtual Chassis Stacking (VCStack™) technology with Link Aggregation. With this approach, all the switches can be connected to form a single virtual switch that can survive a link or equipment failure. “We haven’t had a single switch failure yet,” says Jõesalu, “but we have the technology in place to quickly adapt to help prevent business disruption in the event of equipment failure.”

A second big differentiator that made Allied Telesis the obvious choice is its central management platform, the Allied Telesis Autonomous Management Framework™ (AMF). AMF reduces the time and skill required to maintain the network. Powerful features like centralized management, auto-backup, auto-upgrade, auto-provisioning, and auto-recovery enable plug-and-play networking and zero-touch management.

Within AMF, there is a single console that BRS Networks uses to manage just under 200 Allied Telesis x series switches throughout the HANZA locations. “We have a central AMF Cloud installation,” says Jõesalu. “We use AMF for several other customers too, with all of them centrally managed from our AMF Cloud platform. From the AMF Cloud, dedicated VPN tunnels run to each customer, allowing secure and reliable management of the networks.”

Jõesalu says all the Allied Telesis switches—from the small 8-port to the large 52-port switches—use the same software, which simplifies management. “AMF is a command line environment. Once we log into the AMF Controller, we can do everything we need to do from that single console, whether it’s adding VLANs, backing up the configuration, updating the firmware on the switches, or anything else.”

Many activities are automated to reduce errors and save time. “We can initiate a rolling update of all the switches from the central console,” says Jõesalu. “Then we set the version of the upgrade and the time to run the update. We can let it run overnight or whenever the maintenance window is for each site.”

BRS Networks also uses Allied Telesis Vista Manager EX, which is a graphical interface to the AMF. “Vista Manager allows us to view statistics about the network, and also to do some configuration via a graphical, web-based interface. It’s more intuitive in some cases,” according to Jõesalu.

He adds that the technical support his company has received from the Allied Telesis Nordics team has been outstanding. “We have a relationship with our Allied Telesis counterparts where we can just pick up the phone and call them. With so many other vendors, we’d have to submit a support ticket and wait for a response. Sometimes this can take days. Allied Telesis’ responsiveness helps us serve our customers like HANZA so much better,” says Jõesalu.

A network ready for the future

HANZA is already seeing the benefits of the new network. “The stability in the network is much better,” says Jõesalu. “The facilities no longer experience random disconnections or other issues that could bring the network down. We’re able to make changes in the network without causing business disruption, and that’s a top priority for HANZA.”

The new network perfectly positions HANZA for future growth, both in terms of new customer onboardings and acquisition of additional facilities.
