Decent Cybersecurity has been named one of the 20 key players in the global aerospace and defense cybersecurity market in the newly published 2026 report by MarketsandMarkets, one of the world’s leading B2B research and competitive intelligence firms. The Aerospace & Defense Cybersecurity Market report (Report Code TC 10353) places the company alongside global defense and technology leaders including Thales Group, Lockheed Martin, BAE Systems, Leonardo, Airbus, Northrop Grumman, Honeywell, Rheinmetall and IBM.
Decent Cybersecurity is the only Slovak company in the report and one of just five firms highlighted in its dedicated group of high-growth innovators, which the analysts describe as “agile players specializing in advanced threat detection, encryption, and tactical cybersecurity solutions” for defense and critical infrastructure. For a European SME competing in a market historically dominated by defense primes, the recognition confirms what our aerospace and defense customers already know: sovereign, quantum-resistant security is no longer a niche capability. It is becoming the backbone of the industry.

A market heading toward USD 25.3 billion
According to the report, the global aerospace and defense cybersecurity market is projected to grow from USD 17.0 billion in 2025 to USD 25.3 billion by 2030, at a compound annual growth rate of 8.3%. Behind those numbers sits a threat landscape that has fundamentally changed. Mission-critical systems, satellite networks and autonomous defense platforms are being digitized across every domain, air, land, sea and space, while nation-state cyber warfare and supply chain attacks have moved from theoretical risk to daily operational reality.
The analysts identify escalating geopolitical tensions and state-sponsored cyber operations as the market’s primary growth driver, alongside the accelerating digitization of defense, avionics and satellite systems. In response, defense agencies and aerospace OEMs are replacing legacy security with zero-trust architectures, encrypted communications, AI-based threat detection and, critically, quantum-resilient cryptography designed to protect classified data against both today’s adversaries and tomorrow’s quantum computers.
Post-quantum and space: the fastest-growing fronts
Two findings in the report stand out, because they map directly onto the foundations Decent Cybersecurity was built on.
First, among all solution categories, data, signal and cryptographic security — the segment that explicitly covers post-quantum cryptography and anti-jamming/anti-spoofing technologies — is projected to grow fastest, at 11.1% annually through 2030. Second, among end users, space systems lead the growth table at 11.0%, spanning everything from satellite buses, payloads and inter-satellite links to ground stations and launch facilities.

The report also expects Tier 2 and Tier 3 sub-system suppliers — the SME layer of the defense supply chain to record the highest growth of any organization segment, reflecting a hard-learned lesson: an alliance’s cyber resilience is only as strong as the smallest supplier in its multi-tier supply chain. The analysts name complex, multi-tier defense supply chains as one of the market’s defining challenges, and growing investment in zero-trust and quantum-resilient security as its biggest opportunity.
This is precisely the intersection where Decent Cybersecurity operates. Our portfolio brings post-quantum protection to the domains the report singles out for the strongest growth: PQ-STRAT for post-quantum migration of defense and satellite networks, SpaceShield STM for secure space traffic management, SecureSat Guardian for satellite protection, DroneCrypt UTM for unmanned traffic management, and SynapseCommand for quantum-resistant command and control across air, space and unmanned operations.
In the company of Europe’s defense leaders
The competitive landscape mapped by MarketsandMarkets reads like a who’s who of transatlantic defense technology: Thales Group (France), Lockheed Martin (US), BAE Systems (UK), Leonardo (Italy), Airbus (Netherlands), Northrop Grumman (US), Honeywell (US), Rheinmetall (Germany), General Dynamics Information Technology (US), IBM (US), DXC Technology (US), Booz Allen (US), Hanwha Systems (South Korea), Noventiq (UK) and CS Engineering (US). Alongside them, the report profiles five agile innovators: Decent Cybersecurity (Slovakia), CAVIAR DATA (UK), TYREX (US), Atomus (US) and Globals (India).

The report’s timeline of recent developments underlines how quickly Europe’s cyber defense ecosystem is consolidating: BAE Systems’ collaboration with Sigma Software Group to strengthen cyber resilience for Ukraine and NATO allies, Leonardo’s memorandum of understanding with Indra Group on joint cyber defense for NATO and European markets, and the selection of Thales and SeedFence by the French space agency CNES to deliver onboard cyber detection for space platforms. European sovereignty in defense cybersecurity is no longer an aspiration, it is being contracted, built and deployed.
Built for exactly this market
Recognition in an independent global market report does not happen by accident. Decent Cybersecurity holds national, EU and NATO facility security clearances at the “Secret” level and is certified to ISO 9001 and ISO 27001, independently audited by TÜV SÜD. The company is a registered supplier of the NATO Support and Procurement Agency (NSPA), engaged with the NATO Communications and Information Agency (NCIA), and registered with the European Space Agency across six countries.
The report’s publication caps a strong year for the company. In July 2026, Decent Cybersecurity was selected for the NATO DIANA Decision Superiority Challenge, and it continues to contribute to AIDA, the European Defence Fund project on AI-driven cyber defense. With offices in Slovakia, the Czech Republic, Poland, Austria, Ireland and the United Kingdom, the company delivers post-quantum security, quantum-resistant blockchain and space traffic management solutions to governments, armed forces and critical infrastructure operators across Europe and beyond.
The message of the MarketsandMarkets report is clear: the aerospace and defense sector is entering a decade in which cryptographic resilience, space security and supply chain trust will decide operational advantage. Decent Cybersecurity is proud to be recognized among the companies defining that decade — and ready to help organizations prepare for it today.
