On Thursday, October 2, 2025, the "Kreślarnia" Sports Club in Koszalin took place 39th SPARKCAMP Koszalin meetingAmong the speakers was Piotr Flis, who delivered a lecture on "Digital Sovereignty of Poland and Europe – a Recently Discovered Treasure at the End of the End of History." The thesis of the presentation was powerful: without the state's own capabilities, investments, and human resources in IT, as well as without diversification and resilience, it is difficult to speak of real sovereignty in the era of cloud and AI. The speaker emphasized that data sovereignty – control over storage and use – is today a prerequisite for security and an efficient state.
Against the backdrop of a "naive" vision of the end of history, Piotr Flis exposed the realities of technological geopolitics: from the legacy of Bretton Woods, the threat of the "Thucydides Trap" (US-China tensions), to the race for semiconductor production. He pointed to, among other things, Asia's growing ambitions and the strategic importance of the supply chain for modern chips, a prerequisite for AI development.
In the section on regulations and sanctions, he discussed US instruments (NDAA, BIS actions) and their impact on the market, using Huawei Ascend chips competing with top-of-the-line NVIDIA accelerators as an example. This illustrates how policy shapes technology availability and the pace of innovation.
He also devoted a significant section to the influence of Big Tech: lobbying mechanisms, the scale of spending, and the consequences for public policies in Europe and Poland. The conclusion? We need transparency, standards, and strengthening of domestic science and R&D to avoid becoming a "digital colony."
A worrying limitation to the development of Polish data centers and AI is the limited availability of electricity, as Poland is on the verge of an "energy cliff." Unfortunately, decades of sluggish investment in the energy sector cannot be compensated for. It's worth noting that the construction of a Polish nuclear power plant has been planned since 1971. More on this topic in the article on our technology blog -> Seneca's Cliff, the Limits of Development, Polish AI and Polish Digital Sovereignty.
The whole was concluded with a list of practical recommendations: building competences and research and development facilities, conscious diversification of suppliers, enforcement of privacy and systemic risk analysis as an obligation of decision-makers.
The presentation's punchline was bittersweet – everything is (almost) in our hands, and there are examples of excellent Polish high-tech companies, but, to quote Mikhail Bulgakov, perhaps "Anushka has already bought the sunflower oil (...) she's even spilled it. So the meeting will not take place."
Meeting organizer, SPARKCAMP Association provided live coverage of all presentations and recording, which can be viewed on the SPARKCAMP Facebook page.

On Wednesday, June 11, in the industrial spaces of Concordia Design, we once again hosted our Clients. This time, the topic of the meeting was cyber threats, especially ransomware attacks, and solutions that allow us to defend IT systems against such attacks or minimize their effects.
The meeting was divided into several modules. At the beginning, Piotr Flis (UpGreat) welcomed the guests, presented the agenda of the meeting and emphasized the need for active defense against threats to IT systems in the context of recent attacks on companies and institutions in Poland.
The threat landscape for IT systems in 2025 or what threatens us?
In the next module, Jakub Staśkiewicz (OpenSecurity, Trainer, Auditor, Certified Ethical Hacker) discussed in detail the threats to IT systems in Poland. The most popular attack methods and the mechanisms behind them were presented. The audience learned what a cyber kill chain is, what the Mitre ATT&CK matrix is, and what standard functionalities of operating systems and applications can be used to gain unauthorized access to the data of enterprises and organizations (Lolbin/Lolbas).
In the second part of the module, Jakub Staśkiewicz and Piotr Flis discussed good practices in the area of cybersecurity of IT/OT systems in the form of a dialogue with the audience.
Can storage protect corporate data from encryption?
In this part, Łukasz Bajer (ALEF Polska, storage cybersecurity consultant) discussed the dedicated ransomware protection functionalities of Netapp arrays and showed their operation live. The ONTAP array operating system can recognize the characteristic activity accompanying file encryption by ransomware (AI-powered Autonomous Ransomware Protection – ARP) and take actions appropriate to the set policies, e.g. create a snapshot copy resistant to deletion attempts (SnapLock). ONTAP additionally offers MFA/MAV, i.e. two-factor authentication and the need to provide credentials of more than one administrator when performing particularly important administrative activities. The array also offers digital bunker functionalities (Cyber Vaulting & Air-Gapped WORM).
In his second presentation, Łukasz Bajer introduced the scalable deduplicators from Exagrid. Backup built on the basis of EX-27 – EX189 devices ensures minimal and unchangeable data retention time (Retention Time-Lock), immutable objects (Immutable Objects), as well as delayed deletion of backup copies (Delayed Deletion).
And now Poland! or what IT security products are offered by Polish manufacturers?
Przemysław Kucharzewski (Rublon and CyCommSec) shared knowledge about Rublon MFA and CyCommSec services in two interesting presentations.
Rublon is a Polish company and according to Gartner a major supplier in the field of cybersecurity and a manufacturer of advanced solutions in the field of multi-factor authentication (MFA). The company's flagship product is Rublon MFA - an intuitive and rich in functionalities (over 90 integrations with devices and software) platform, enabling secure employee access to the organization's IT resources and achieving compliance with data protection regulations.

On Thursday, May 22nd at Concordia Design, we had the pleasure of presenting Huawei Enterprise technologies to our guests. In today's polarized world, in a situation of retreat from globalized supply chains, it is important to diversify suppliers and build your own digital sovereignty. We proposed Huawei products as one of the elements of an alternative to American technologies, without which, let's be honest, a modern company cannot function.
The meeting was divided into three modules.
More about UpGreat and the challenges for IT in times of deglobalization
The meeting began with a short presentation of the UpGreat Systemy Komputerowe company, present on the IT solutions market until 1990. The President of the Management Board of UpGreat Systemy Komputerowe, Piotr Flis, briefly described the company's history, presented its offer and its Customers and technology partners, among whom Huawei Enterprise recently appeared alongside the well-known companies Cisco, HPE, Fortinet, Microsoft, Netapp and others.
In the second part of his presentation, Piotr Flis presented a cross-section of national interests and strategic goals of the Republic of Poland, talked about the Thucydides trap and the business model of American big-techs, and about the theft of private data by states and technology companies. There was also hard data comparing the economies of the US and China, business development models of companies in both countries, R&D expenditures and deindustrialization of the American economy.
JWhat storage solutions does Huawei provide? So what are OceanStore Dorado and OceanProtect?
In this part of the meeting, Konrad Tutak from Huawei told the audience about Huawei's legacy platforms – the all-flash OceanStor Dorado and the hybrid OceanStor, as well as the OceanStor Protect backup platforms. Sales of all-flash storage put Huawei in second place in the world (19.0%) just behind Dell/EMC (20.5%).
In this part of the seminar, Arkadiusz Giedrojć introduced issues related to wired and wireless networks. Huawei offers a full portfolio of efficient backbone, aggregation and access switches with interfaces from 1Gb/s to even 400Gb/s. In addition, there is a rich family of routers and solutions for SD-WAN networks. The offer also includes ultra-fast access points compliant with the WiFi-7 standard.

On Friday, November 29, we had the pleasure of hosting Customers and engineers from Cisco Systems at a business breakfast dedicated to network solutions for industry. Extreme conditions in production halls, steel mills, on the railway or in the power industry place high demands on network devices - high and low temperatures, dust, high humidity and an aggressive atmosphere mean that none of the devices designed for office applications, such as the Catalyst 9000 series, will provide stable operation for OT systems. That is why there is a whole range of products dedicated to industry. In addition to resistance to environmental conditions, industrial devices should be resistant to various types of threats from cybercriminals.
The meeting was divided into several modules.
More about UpGreat
The meeting began with a short presentation by UpGreat Systemy Komputerowe, known for specializing in network solutions and a long-time partner of Cisco Systems. Participants had the opportunity to learn about the history of the company, its offer and clients.
The UpGreat presentation is available for download -> here.
What are the general characteristics of industrial networks and what are their use cases?
In this part of the presentation, Michał Małuszek from Cisco told the audience in which industries industrial networks operate (production, energy, petrochemical and gas, energy, railways, road infrastructure and others), as well as in what conditions devices operate (from -50°C to +75°C, humidity, dust, vibrations, aggressive atmosphere). The portfolio and advantages of Cisco industrial devices were also presented.
The presentation on industrial networks is available for download -> here.
What is the specificity of industrial wireless networks?
Marcin Szreter from Cisco presented specific Cisco wireless solutions and showed that wireless networks are not just WiFi. Some of the applications require extremely low latency, roaming without packet loss or data transmission from objects moving at very high speed. Cisco Ultra-Reliable Wireless Backhaul (URWB) was also presented - a wireless network "as reliable as fiber". URWB means latency < 10ms, transfer up to 4.8Gbps, unlicensed frequencies and availability up to 99.995%.
The presentation on industrial wireless networks is available for download -> here.
How OT and IT networks can be integrated and what is Cisco SDA
In the next session, Miłosz Wrona talked about the family of software defined networks solutions – Cisco SDA (Software Defined Access). This approach allows for the creation of a structure (fabric) of wired and wireless devices that provide secure, efficient, reliable access to the network for end devices based on user identification. Cisco SD-Access enables efficient management of access to the network as a whole from a single console – everyone has access to what and only what they should have. The network is managed using Cisco DNA Center with the support of Cisco ISE (Identity Services Engine).
The Cisco SDA presentation is available for download -> here.
How to keep your OT network safe
Finally, Marcin Szreter once again brought up the subject of OT network security. The specificity of some devices used in industry, until recently not having contact with IT networks, is the possibility of various vulnerabilities exposing companies to disruptions in the continuity of key processes. At the same time, the requirements of the NIS-2 directive will soon be imposed on many companies in the industrial sector. Cisco Systems proposes a comprehensive approach to OT security issues based on Zero Trust Network Access (ZTNA), division of the network into trust zones related to, for example, production lines and active analysis of events in the network and response to threats (Incident Investigation & Response). In this context, Cisco Talos Threat Intelligence and Talos Incident Response were discussed.
Additionally, full situational awareness in the OT environment is provided by Cisco Cyber Vision Center and Cyber Vision Sensors, which enable passive analysis of network communications to continuously inventory the network and obtain information about possible vulnerabilities of used devices.
