Methodology and sourcing behind the figures shown above.

Cross-domain data transfer

Estimate based primarily on industry market reports in the search results. Fortune Business Insights values the global cross-domain solutions market at USD 2.7B (2025) with a 10.89% CAGR; Zion Market Research (USD 2.78B in 2023, CAGR 10.2%) and MarketIntelo (USD 2.1B in 2025, CAGR 7.8%) corroborate a multi-billion-dollar market with high-single- to low-double-digit CAGR. I selected Fortune’s 2025 valuation and reported CAGR as the primary point estimate, corroborated by the other reports.

Isolated cyber environment provisioning

Estimation anchored to published global cybersecurity market sizes and a relevant OT/industrial cybersecurity submarket. Global cybersecurity is quoted at ~US$254.8B (2025) and growing ~13.8% CAGR; industrial/OT security is ~US$23.8B (2025). Isolated cyber environment provisioning is a niche (secure, self-contained workload/environment provisioning used for testing, mission systems, enclaves) within cloud/enterprise/industrial security. I estimate the segment is a small share (~1–2%) of the broader 2025 cybersecurity market, yielding ~US$3.5B in 2025, and likely to grow modestly faster than the overall market due to accelerating cloud migration, DevSecOps, zero-trust and enclave adoption—hence a projected CAGR around 16% (above the 13.8% overall cybersecurity CAGR).

Identity and access management

Primary estimate uses MarketsandMarkets' 2025 IAM market value of USD 25.96B and their 10.4% CAGR (2025–2030). Other sources show a range (Fortune: ~22.3B in 2025, 15.1% CAGR; miniOrange: ~27.5B/12.6% earlier). I selected MarketsandMarkets as the primary projection while noting a 10–15% observed CAGR range across reports.

Removable media decontamination

Search results show the broader bio-/decontamination equipment and services market is small (USD ~0.22–0.32B) but growing (CAGR ~4.7–9.7%); larger decontamination systems markets (all industries) are multi‑billion. Removable media decontamination is a narrow IT/OT niche within these markets (specialized appliances/services, small installed base). Using the bio‑decontamination market as an upper‑bound and estimating removable‑media share as a single‑digit percent of that addressable market, I estimate ~USD 0.1B current market size with faster adoption in OT/security environments implying ~8% CAGR (aligned with higher-growth decontamination segments and cybersecurity/OT protection trends).

Mobile communications protection

Primary estimate uses Persistence Market Research’s secure mobile communications report (explicitly covering secure/mission-grade mobile communications), which projects US$28.5B in 2026 and a 19.8% CAGR to 2033. Broader mobile-security market reports from Fortune Business Insights and Zion Market Research show comparable market sizes and ~21% CAGR ranges, corroborating a high-growth trajectory for secure mobile communications solutions.
