Ares Shield has developed a system that uses microwaves to neutralize unauthorized data interception attempts, positioning the Wrocław-based firm as a key partner for the American defense sector. This solution enables active protection of satellite communications by physically jamming signals attempting to seize control of orbital infrastructure. In doing so, Grzegorz Zwoliński's company is entering a strategically significant security segment, aiming directly at the Pentagon's rigorous requirements.
Grzegorz Zwoliński, after closing the chapter known as SatRev, has not withdrawn from the space technology sector. Instead of building more satellite constellations, he decided to focus on securing the objects already in orbit. Ares Shield, a Wrocław-based company registered and developed with the global defense market in mind, is an attempt to address the growing problem of microwave espionage. In the space industry of 2026, where data is becoming more important than the hardware itself, this approach is viewed as meeting the needs of the American military complex.
The experience gained from managing SatRev became a lesson for Zwoliński regarding the vulnerabilities of orbital communication. Understanding satellite architecture, their susceptibility to "man-in-the-middle" attacks, and the limitations associated with software-level encryption allowed for the creation of a defense concept based on the physical signal layer. This is a shift from passive threat monitoring to active electronic warfare in space.
The American defense market, to which Ares Shield aspires, does not forgive a lack of precision. Companies entering this level of the game must meet strict ITAR certification standards. For the Polish startup, this means the necessity of proving that the technology is not just a theoretical model, but a module ready for integration. Zwoliński's ambitions extend beyond local research grants, targeting contracts where budgets are counted in millions of dollars. Competing with American defense giants, such as Lockheed Martin or Northrop Grumman, requires Ares Shield not only to innovate but, above all, to provide reliability confirmed in field tests.
The scalability of such systems remains the biggest engineering challenge. Integrating a microwave shield with the existing fleet of American satellites is an operation fraught with the risk of disrupting one's own communication systems. If the Polish company manages to eliminate so-called self-noise while maintaining effectiveness in blocking intruders, it will find itself in a narrow group of critical technology suppliers for the USA. Otherwise, a lack of evidence of effectiveness in operational conditions could quickly close the door to American defense budgets.
Microwave technology: A defense mechanism in a vacuum
The Ares Shield system is based on the concept of active neutralization of intercepting signals. Unlike standard cryptographic systems that secure the content of messages, the Wrocław-based technology focuses on the integrity of the transmission channel itself. The mechanism uses a precisely modulated microwave beam that detects anomalies in data transmission between the satellite and the ground station in a fraction of a second.
The key process, which the company describes as an "active shield," involves introducing controlled interference in the band where the intruder is operating. Instead of waiting for a full signal interception, the system detects an attempt to log into the radio channel. Then, by emitting a microwave at a specific frequency, it creates a barrier that prevents the hostile unit from establishing a stable connection. This is a process reminiscent of jamming systems, but on an orbital scale, where precision must be calculated in microseconds.
The aforementioned signal modulation is not just a theoretical construct. It is based on real-time radio signal analysis algorithms that allow for the distinction between background noise and an interference attempt. In space conditions, where every milliwatt of energy is precious, the Ares Shield system must be extremely energy-efficient. The challenge lies in ensuring the shield operates selectively—blocking attacks without interrupting one's own data transmission.
For the engineers working on this solution, the most difficult stage is calibrating the system under conditions of orbital variability. Satellites move at enormous speeds, which changes the radio wave propagation parameters. Ares Shield must therefore dynamically adjust the power and direction of the microwave beam. This requires advanced phased-array control systems, which are currently standard in modern military radars, but their miniaturization to the satellite level remains a challenge for global engineering.
Industry skeptics point out that any attempt at physical interference with a radio signal could be interpreted by hostile nations as an act of aggression. In space, where borders are conventional and "espionage" is difficult to prove definitively, the use of microwave systems could lead to an escalation of tensions. Ares Shield must therefore operate in an extremely discreet manner so as not to be accused of conducting warfare in orbit. This makes the implementation of this system not only a technical challenge but also a political one.
The US market as a testing ground
Why did the American market become the target for Ares Shield? The answer is simple: nowhere else is the demand for "space security" so high and backed by such vast funds. In recent years, the Pentagon has changed its approach to satellite protection, recognizing them as critical infrastructure that must be capable of surviving in conditions of hybrid conflict. The Wrocław-based startup is entering this gap, offering a solution that American defense giants often do not have in their portfolios, as they usually focus on building the satellites themselves rather than their radio protection.
The contract, which is being discussed in the context of entering the US market, is intended to be the first test of the real utility of Zwoliński's technology. These are not funds for basic research, but resources for a pilot implementation. Such status as a partner, rather than just a subcontractor, allows for access to American satellite technologies, which opens up the possibility of further development for Ares Shield.
However, entering the US defense ecosystem is an endless series of audits for a Polish company. ITAR (International Traffic in Arms Regulations) regulations are a barrier that requires full management and technological transparency to cross. Every component used in the system must have origin certification. For a company from Poland, this is a huge operational cost. However, if Ares Shield maintains its pace, it could become a permanent link in the supply chain for the US Department of Defense.
Americans do not choose partners out of sentiment. If the Wrocław-based technology does not prove itself in tests, the contract will not be renewed. This is a brutal rule that Zwoliński learned back in the days of SatRev. The difference is that this time the stakes are much higher – it is about the national security of a superpower. This is not a hobby project. This is a business where a mistake means not only a loss of capital but also a loss of reputation in an industry where trust is built over years.
Significance for the space sector in Poland
The success of Ares Shield could redefine the position of Polish companies in the global space sector supply chain. For years, Poland was perceived as a country providing software or simple mechanical components. Moving into the area of critical infrastructure protection is an advancement to the major leagues. If the Wrocław-based company succeeds in the USA, it will become a magnet for engineering talent from all over Central Europe, who until now have emigrated across the ocean.
Investors are looking at this move with moderate optimism. On one hand, microwave technology has huge growth potential. On the other, the history of SatRev taught the market that in the space industry, the distance between a prototype and a working system in orbit is enormous. Any delays in certification or testing could be perceived as a warning sign.
It is worth noting that the Polish government is increasingly actively supporting companies in the "space security" industry, treating them as an element of the country's defense strategy. Ares Shield's cooperation with American partners could become the basis for building a broader technological alliance. If Polish technology becomes a standard in American satellites, it will be easier to implement it in European projects, e.g., within the framework of ESA (European Space Agency) initiatives.
For the reader, this means that the Polish contribution to global security is becoming a fact, not just a declaration. Ares Shield does not build rockets, it does not send people into space, but it builds an invisible shield that protects the data transmitted over our heads. This is a new type of space business – based on defense and cybersecurity, rather than exploration.
Security challenges in orbit: The year 2026
Orbit in 2026 is a place of permanent surveillance. The number of satellites in low Earth orbit (LEO) has grown to levels that make it impossible to have full control over every transmission. Microwave espionage has become a favorite tool of state players because it allows for data interception without physically damaging the satellite, which makes it difficult to attribute an attack to a specific entity.
In this environment, Ares Shield is positioning itself as a provider of "orbital police." Their system not only detects an intruder but actively discourages further interception attempts. This is a "zero trust" approach transferred from network cybersecurity to the physical radio layer. In the face of rising geopolitical tensions, such technology is becoming a scarce commodity.
Skeptics note, however, that increasing the number of jamming systems in orbit could lead to a "Kessler syndrome" in an electronic version – the orbit will become so radio-noisy that normal communication will be almost impossible. Grzegorz Zwoliński's company must prove that their microwave shield is precise enough not to paralyze the work of neighboring satellites. If the system generates too much interference, it will become a problem for the entire LEO ecosystem, not its solution.
The investment risk is therefore enormous. Dependence on American export regulations makes Ares Shield a hostage to Washington's policy. In the event of a tightening of policy toward European subcontractors, the company could be blocked in its main market. Therefore, the company's development strategy must include diversification, which, given the current focus on the USA, seems difficult to achieve in the short term.
Development plans and prospects: What's next?
The future of Ares Shield depends on the results of the first contracts in the USA. If the company confirms the effectiveness of the microwave shield, a market worth billions of dollars opens up for it. Development plans include not only the protection of military satellites but also commercial ones belonging to corporations transmitting sensitive data.
Zwoliński's company has a chance to become a leader in a new niche. Using microwaves to protect satellite data is a technology that will gain importance in the coming years along with the further militarization of space. The Wrocław-based company is in a good place, but time is working against it – the competition is not sleeping and is certainly working on its own solutions in this area.
Will Ares Shield repeat the success of American defense companies? Everything depends on how they handle technical challenges in the coming months. The market does not forgive mistakes, and in space, every error is final. If the system fails during a test, there will be no third chance for Grzegorz Zwoliński in the same segment.
What does this mean for you?
The success of Ares Shield means that the data you send via satellites – from weather forecasts to banking data and government communications – is becoming slightly safer thanks to Polish technical thought. On the other hand, the growing number of defense systems in orbit increases the risk of electronic conflicts over our heads. As users of satellite technology, we will witness an increasingly complicated fight for signal purity in space.
