Managed detection and response

Continuous monitoring, detection, and 24/7 response across endpoints, networks, and cloud with US-based SOC oversight and integrated threat intelligence.

Market size: $6.2B CAGR: 20%
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

Rapid breach containment, forensic coordination, eradication, and post-incident analysis to restore operations and improve response capability.

Market size: $46.6B CAGR: 15%
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

Ongoing monitoring and research to detect compromised data, provide threat intelligence, and support incident investigations and risk awareness.

Market size: $15.0B CAGR: 15%
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

Advisory and delivery for controls readiness (including SOX), IT and operational risk management, internal audit and risk assurance, and regulatory compliance programs.

Market size: $34.0B CAGR: 3.9%
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

Hands-on developer education, secure-coding training, certification readiness (including EU Common Criteria) and practical exercises to build secure software and prepare products for certification.

Market size: $1.0B CAGR: 12%
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).
