European cybersecurity startups moved further into the venture capital spotlight on October 16, 2026, as Tech Funding News published a new selection of seven companies attracting investor attention. The report arrives during a period of increasing demand for artificial intelligence security, advanced encryption and automated cyber defenses, with European developers seeking a larger role in a market historically dominated by major American technology companies.

The publication, in an article by Sofia Chesnokova, cited PitchBook data indicating that European cybersecurity startups raised approximately $1 billion across 61 venture capital transactions during the first quarter of 2026. The figures suggest continued investor interest in technologies intended to protect enterprise software, sensitive information and critical digital infrastructure.

The complete seven-company selection is available through the publication’s subscription offering. However, publicly disclosed investments and company announcements provide an independent view of seven European cybersecurity businesses illustrating the technologies and commercial opportunities attracting venture capital. These companies are not presented as a verified reproduction of the original ranking.

The growing investment interest reflects a change in the cybersecurity industry’s priorities. Traditional security software concentrated heavily on identifying malicious activity, protecting networks and responding to intrusions. Newer companies increasingly address vulnerabilities associated with automated software development, AI agents, cloud infrastructure, sensitive-data processing and human behavior.

Belfort, a Belgian technology company spun out of KU Leuven, represents the emerging field of privacy-preserving computation. Its technology is designed to accelerate operations on encrypted data, potentially enabling sensitive information to be processed without first exposing it in readable form.

The company announced a $6 million seed financing round in September 2025 led by Vsquared Ventures. Its investors included several international venture capital firms and technology entrepreneurs. Belfort said the financing would support product development, hiring and enterprise pilots involving its operations in Leuven and San Francisco.

The American connection is significant because secure data processing could support applications involving financial information, healthcare records and government systems. Although the technology’s commercial adoption remains subject to performance, integration and cost considerations, Belfort illustrates investor interest in security infrastructure that extends beyond conventional software monitoring.

Another example is Aikido Security, the Belgium-based developer of a platform designed to help software teams identify and address security vulnerabilities throughout the development process.

In January 2026, Aikido announced a $60 million Series B investment at a $1 billion valuation. DST Global led the financing, with participation from other investors. The company’s platform brings together code security, cloud security and application protection, reflecting demand for tools that integrate security directly into software engineering workflows.

Reuters reported that approximately half of Aikido’s revenue at the time came from the United States. That geographic mix demonstrates how European cybersecurity companies can pursue American customers early in their development rather than relying exclusively on domestic markets before expanding internationally.

The accelerating adoption of AI-generated software creates another commercial opportunity. Development teams can produce and deploy code more quickly, but that increased speed may also complicate security review. Platforms that continuously identify vulnerabilities and help developers prioritize fixes could become increasingly valuable to organizations operating large software environments.

France-based Filigran represents a different cybersecurity category: threat intelligence and proactive security validation. Founded in 2022, the company has developed open-source-rooted technologies intended to help organizations understand threats, evaluate their exposure and test defenses against possible attacks.

Filigran announced substantial American business growth in March 2026. According to the company, its North American annual recurring revenue had increased nearly fourfold year over year, while its U.S. business had expanded through additional enterprise and government customers. Those figures were company-reported and were not independently audited for this article.

The company has also attracted significant financing. Its previously announced $58 million Series C included support from investors such as Eurazeo, Deutsche Telekom, Accel and Insight Partners. Filigran’s development illustrates demand for tools connecting cyber threat intelligence with operational security decisions.

Finland-based Hoxhunt focuses on the human element of cybersecurity. Its platform uses AI-supported training and behavioral techniques to help employees recognize and report phishing attempts and other suspicious communications.

Hoxhunt announced a partnership with U.S. cybersecurity solutions provider GuidePoint Security in January 2026, extending the availability of its platform through an American enterprise security distribution network. The relationship reflects an important commercialization strategy for European software companies: working with established U.S. partners to reach security buyers.

Employee-focused cybersecurity remains relevant despite advances in automated protection because social engineering and credential theft can exploit weaknesses that network defenses alone do not eliminate. AI-generated communications also create additional challenges for organizations trying to distinguish legitimate messages from deception.

Estonia-based Blackwall illustrates investment in web infrastructure protection. Previously known as BotGuard, the company announced a €45 million Series B financing round in March 2025 led by Dawn Capital. Its services focus on protecting websites and online applications from malicious automated traffic.

Blackwall has emphasized distribution through hosting providers, managed service providers and digital platforms. Its expansion plans have included the United States and Asia-Pacific, positioning the business in a market where American companies already offer extensive bot management and web application security services.

France’s Zama represents another approach to data security through fully homomorphic encryption, or FHE. The cryptographic technology allows certain computations to take place on encrypted information without exposing the underlying data during processing.

Zama has pursued applications involving blockchain confidentiality and privacy-preserving computation. In January 2026, the company reported that its encrypted token auction attracted approximately $118.5 million in commitments. The transaction was distinct from a conventional venture capital financing round, but it provided a public demonstration of the technology’s use in a production environment.

Such approaches could eventually support additional confidentiality requirements in financial applications and other information-sensitive systems. Their wider adoption will depend on technical scalability, security assurances and whether users find clear advantages over existing infrastructure.

Mindgard, a cybersecurity business originating from research at Britain’s Lancaster University, addresses vulnerabilities in artificial intelligence systems themselves. Its technology focuses on assessing the security of AI models, agents and applications against adversarial techniques.

In August 2026, Mindgard announced a $30 million Series A financing led by Album VC, with participation from additional investors. The company disclosed plans to expand its product development and commercial operations. Its connections to both British academic research and the American enterprise market illustrate how cybersecurity innovation increasingly crosses national boundaries.

The wider European environment provides important context for these developments. Technology consultancy Wavestone’s European Cybersecurity Startup Radar 2026 examined 728 startups, scale-ups and unicorns across Belgium, France, Germany, Luxembourg, Switzerland and the United Kingdom.

The research identified different national strengths, including cryptography, identity management, application security, data protection and regulatory compliance. It also found that artificial intelligence is becoming more widely incorporated into security products, although individual companies differ considerably in their technical maturity and commercial reach.

In its separate United Kingdom research, Wavestone reported that 62% of surveyed cybersecurity startups incorporated AI into their products, compared with 30% in the previous year’s edition. The figures demonstrate broader adoption of AI-enabled security functions, rather than proving that those products are necessarily more effective than alternatives.

The same study identified commercial challenges. Approximately 38% of surveyed British cybersecurity startups reported difficulty finding prospective customers, while other obstacles included completing sales, obtaining financing and recruiting employees.

Those problems are particularly relevant when European companies pursue American enterprise contracts. Security buyers frequently require extensive technical evaluation, regulatory documentation, integration testing and evidence that new suppliers can provide reliable support over several years.

For Silicon Valley investors, the opportunity lies partly in identifying European companies with differentiated technology before they achieve substantial international scale. Venture investors may also look for businesses with established American demand, defensible intellectual property and products that address security requirements created by rapidly changing AI infrastructure.

At the same time, venture funding announcements and private-market valuations do not establish long-term profitability or commercial success. Companies operating in cybersecurity face intense competition, evolving threats and the need to demonstrate that their technologies meaningfully reduce risk.

The latest investor attention therefore highlights both opportunity and uncertainty. European cybersecurity businesses are developing increasingly specialized products, while American enterprises remain important prospective customers and commercial partners. Whether the newest generation of companies can translate their technology into lasting international market positions will depend on adoption, execution and measurable security outcomes.
