    Communication in the middle of nowhere: radio link + Meraki

    Frequent Internet interruptions or low transfer speeds hampered the company’s operations and gradually led to frustration among its employees who were unable to perform their tasks. Since the company does not have its own IT team dedicated to this type of challenge, the decision-makers decided to look for a solution outside. Due to good relationships and trust, Grandmetric was chosen for this challenge.

    Security audit of IT infrastructure

    In a modern manufacturing company, IT infrastructure is critical for its smooth functioning. Data security, ease of work of all departments, management and the entire production process depend on it. If something is not working properly, a serious failure is only a matter of time. With it, production, distribution and sales will also stop, and therefore – huge losses will be generated every second.

    Młyny Szczepanki took this risk into account and decided to conduct an audit of the IT infrastructure. In this way, the organization counteracts a disaster by locating and eliminating potential trouble spots.

    Anonymization of surveillance recordings improves the complaint process by 2/3

    The manufacturing company had trouble tracking complaints. Reaching the appropriate recording after a long time (sometimes 6 or more months) and finding irregularities on individual technological lines took too much time for the IT department. Another problem was the fact that there was no ready-made solution on the market that would fully meet the customer’s needs.

    A properly configured Hikvision recorder with a module written for the client’s needs that allows for anonymization of recordings coped with this problem.

    Ansible automation reduces response time to requests by 80%

    Actions performed using the application are several times faster than configuring many devices manually, and additionally, allow you to avoid errors during manual configuration. Now you do not need a network specialist to connect a printer to the appropriate switch port or quickly find the desired device on the network. Qualified engineers gained time to solve advanced problems.

    Phishing blocked. All it took was 24 hours and Cisco Umbrella.

    How to ensure security when the number of remote workers is growing and cloud applications are being introduced on a large scale? A centralized, local security model is becoming increasingly impractical. The client wanted to meet these problems and decided to look for a solution that would protect the company against cyberattacks, mainly phishing and malware. He also wanted a convenient management panel.

    Cisco Meraki implementation in the office and high-bay warehouse

    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.

    Optimization of filtering rules on Fortigate 200F firewalls

    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.

    Site survey of wireless network in a global eCommerce

    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.

    Migration of IP and PSTN interconnections to a global operator

    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. 

    First implementation of Cisco SD-WAN in Europe

    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
