The cybersecurity and critical infrastructure sector in Spain has a new benchmark for growth. S2GRUPO, a company specialized in IT+OT cybersecurity, intelligence and cyber defense, has confirmed after auditing its accounts financial results that mark a milestone in its trajectory: revenue of €56.19 million in fiscal year 2025, representing a 54% increase over the previous year, and an EBITDA of 10%.

Sustained growth that exceeds expectations

These results are not a matter of chance. According to the company in an official statement, the good performance of all business units, combined with operational efficiency derived from the internal reorganization undertaken in the previous year, has been key. In addition, the advancement of proprietary technology has become a lever for differentiation and margin improvement. In the period 2021-2025, S2GRUPO records a compound annual growth rate (CAGR) of 24.7%, demonstrating a solid and consistent trajectory.

José Miguel Rosell, CEO and co-founder of S2GRUPO, stated: “The strength in key industrial sectors and critical infrastructures, the advancement of our proprietary technology and the response to the challenges posed by AI and quantum computing are the best demonstration that we have been building the capabilities that Europe currently needs for years. The moment we anticipated has arrived, and we are in a position to lead it.” These statements reflect the company's ambition to position itself as a relevant player in the cybersecurity and defense ecosystem at the continental level.

IT+OT cybersecurity and cyber defense: the strategic core

One of the pillars of S2GRUPO's growth is its positioning in the cybersecurity, intelligence and cyber defense markets. Its comprehensive capabilities in IT+OT cybersecurity (Information Technology and Operational Technology) have allowed it to actively participate in strategic national cyber defense programs linked to the Joint Cyber Command (MCCE). In addition, it maintains long-standing industrial alliances with reference groups such as Indra, Navantia and Siemens, reinforcing its role in critical projects for national security.

In a context where technological sovereignty and the protection of strategic infrastructures are priorities for governments and companies, S2GRUPO's industrial cybersecurity offering becomes especially relevant. This unit specializes in protecting OT environments and control systems in sectors such as energy, industry, healthcare and transportation, areas where a cyberattack can have devastating consequences.

Managed services and proprietary technology: the other leg of growth

Beyond cyber defense, S2GRUPO's managed services unit has also seen significant progress. This area offers monitoring, vulnerability management and incident response solutions, allowing companies to outsource part of their security without losing control. The combination of managed services with proprietary technology, developed internally, allows the company to offer differentiated solutions that adapt to each client's specific needs.

The commitment to innovation does not stop here. S2GRUPO is actively exploring how artificial intelligence and quantum computing can transform cybersecurity. In this sense, the company aligns with global trends such as those seen in generative AI models or in the development of autonomous agents, although applied to early threat detection and response.

Talent and diversity: a growing workforce

Behind these results there is a key human factor. S2GRUPO's workforce currently consists of more than 700 cybersecurity professionals, representing a 25% growth over the last five years. The company has made a strong commitment to talent, recruiting high-level technical profiles and promoting continuous training. A notable fact is female representation, which already reaches 24% of the workforce, exceeding the average in the Spanish technology sector, where the gender gap remains a challenge.

This focus on talent not only drives the company's innovative capacity, but also reinforces its positioning as an attractive employer in a labor market where cybersecurity experts are increasingly in demand. Talent retention is, in fact, one of the pillars of system hardening and secure infrastructure management, areas where S2GRUPO offers advanced services.

Impact on the business ecosystem and future prospects

S2GRUPO's growth is not an isolated case, but reflects a broader trend in the cybersecurity sector in Spain. Companies like Grupo Magellan are also betting on technological sovereignty and comprehensive coverage of the digital value chain. However, S2GRUPO stands out for its focus on critical infrastructures and its collaboration with the military sphere, which gives it a unique position in the market.

Looking ahead, the company is optimistic. The Strategic Plan 2025-2030, whose first year of execution has been a success, lays the foundations for continued growth. The combination of proprietary technology, strategic alliances and an expanding workforce suggests that S2GRUPO could double its revenue in the coming years, especially if the demand for cybersecurity continues to rise driven by digitalization and geopolitics. In a world where industrial AI and 5G connectivity open new doors, cybersecurity becomes an indispensable enabler.
