Unidirectional network gateways

Estimated 2026 market size and growth are synthesized from multiple market reports in the provided search results. Reported 2025–2026 valuations range from USD 0.33B to USD 1.3B (one source uses 2025 base); reported CAGRs range roughly 5.6%–12.8%. I used a midpoint approach (average of the 2026/2025 reported values mapped to 2026 and the reported CAGRs) to produce a single, conservative estimate reflecting differing vendor methodologies and market definitions.

High-assurance unidirectional gateways

Published market reports for unidirectional/data-diode gateways diverge (2025–2026 values range ~USD 0.33B–1.2B; reported CAGRs span ~5.6%–12.8%). I used the median/central tendency of these search-result estimates (favoring the 2026 datapoints ~USD 0.33B and ~USD 0.508B and the 2025 $1.2B report) to derive a conservative midpoint market size (~USD 0.51B) and a median CAGR (~9.5%) reflecting continued demand in government, defense, and critical infrastructure for ruggedized, certified one‑way gateways.

Governance, risk and compliance (GRC) platforms

Estimate based on MarketsandMarkets eGRC market sizing (aligned with enterprise GRC platforms): market projected at USD 20.56B in 2025 and growing to USD 39.99B by 2030 (CAGR 14.2%). Verdantix provides a narrower GRC software figure (~USD 4.98B in 2023; CAGR 11% to 2029), indicating scope differences (software-only vs. broader eGRC platforms + services).
