Methodology and sourcing behind the figures shown above.

Managed detection and response

Multiple industry reports in the searchResults show the global MDR market in the low-to-mid single-digit billions (2024–2026) with high projected growth. Reported 2026 market sizes range ~USD 2.8B–6.2B and horizon CAGRs range ~15%–23%. I selected USD 6.22B (MarketsandMarkets 2026 figure) as a representative current-market estimate and a consensus growth potential of ~20% CAGR reflecting the mid-point of reported forecasts (17.8%–23.2%), acknowledging definitional differences across reports (scope, inclusion of platforms/services, forecast periods).

Incident response and forensics

Estimated 2025 market size derived by combining reported incident response and digital forensics market figures from the search results (38.67B + 12.94B = 51.61B) and reducing ~5.0B to conservatively account for overlap between incident response and forensics offerings, yielding ~46.61B. CAGR set to 15.0% as a midpoint reflecting reported growth rates for incident response (~20.2%), digital forensics (~12.0%), and network forensics (~17.45%), weighted conservatively to reflect overlap and differing forecast windows.

Threat intelligence and dark web monitoring

Estimated current market size (~2025) derived from multiple industry reports in the provided results (MarketsandMarkets, Precedence Research, ResearchNester). These sources report 2025 market values in the $11.6–16.8B range and multi-year forecasts implying mid-teens CAGRs (~14.5–15%). I weighted recent 2025 point estimates (11.6, 15.6, 16.8) to produce a rounded $15B size and selected a consensus CAGR of ~15% (consistent with 14.7%–15.2% range in the sources).

Governance, risk and compliance advisory

Primary estimate uses the WiseGuy Reports figure valuing the global risk & compliance consulting (advisory) market at USD 34B in 2025 with a 3.9% CAGR (2026–2035). I cross-checked other search results showing a range driven by definitional differences: BusinessResearchInsights (USD 17.87B in 2026; 6% CAGR) and IndustryResearch (USD 11.36B in 2026; 5.31% CAGR) for narrower scopes, while MarketsandMarkets reports a larger eGRC software market (USD 20.56B in 2025 to USD 39.99B in 2030; 14.2% CAGR). Given the search-result variance, the advisory services estimate follows WiseGuy’s consulting-focused sizing and growth rate, with other sources shown to illustrate range and methodological differences.

Developer security training and certification readiness

Estimate based on reported niche secure-code training market (~USD 0.8B in 2026) and broader cybersecurity certification/training market figures (cybersecurity certification ~USD 3.98B in 2024, broader training markets $1.8–4.4B range). Developer security training and certification-readiness is a subset of both secure-code training and certification services; I set current market size at ~USD 1.0B and growth potential aligned with certification and training CAGR signals (~12% annual growth).
