Case studies

Wireless transmission solutions, such as Cisco Meraki, must keep up with the rapidly changing needs of not only global corporations, but also small and medium enterprises. Global Wind Service, a company servicing wind turbines in Europe, asked us to design a secure wireless network that would cope with a variable number of employees in the office, as well as ensure the appropriate connection in the warehouse where turbine parts are stored. The condition set by the client was the ability to manage the infrastructure in the cloud.

A firewall is a basic element of corporate data protection. Its role is to allow or block traffic, which is based on filters set on individual ports. The problem arises when the Firewall configuration gets out of hand.

Our goal was to audit the Fortigate 200F cluster configuration and prepare optimal traffic control rules. For this purpose, we have built our own flow visualization tool based on Kibana and Elasticstack.

Our client was faced with poor Wi-Fi quality in three offices located in different European cities.  Network problems manifested in low throughput, cutting connections, and low quality of video calls. Thanks to our recommendations after the audit, our client’s network gained back its efficiency, and the users – comfort of using company Wi-Fi.

When lack of standards in voice communication causes excessive costs of infrastructure maintenance and, as result, blocks its development, migration of VoIP and PSTN interconnections towards a global SIP operator is in fact a step towards the digital transformation of the entire organization.  

Our goal was to prepare for the migration of voice services to one, the global operator providing local PSTN interconnections. We also combined Microsoft Teams, Cisco Voice, and Session Border Controllers (SBC) into one, scalable structure. 

When the efficiency of the company’s applications and employees rely on network connectivity in their professional activities, a reliable and fast network between the company’s locations is fundamental for each organization.

Now, WAN and Internet links in each location are 5 to 10 times faster than before the migration to SD-WAN. This increase in available bandwidth is inversely proportional to links’ cost, which has decreased by around 40%., says Marcin Jaźwiec, IT Manager of Pfeifer and Langen Poland
