Market Size Estimation
Both the top-down and bottom-up approaches were used to estimate and validate the size of the defense cybersecurity market. The following figure represents the overall market size estimation process employed for this study on the market.
The research methodology used to estimate the market size included the following details:
-
Secondary research identified key players in the defense cybersecurity market, and their market share was determined through primary and secondary research. This included a study of annual and financial reports of top market players and extensive interviews of leaders such as CEOs, directors, and marketing executives of leading companies operating in the market.
-
All percentage shares, splits, and breakdowns were determined using secondary sources and verified through primary sources.
-
All possible parameters that affect the markets covered in this research study were accounted for, viewed in extensive detail, verified through primary research, and analyzed to obtain the final quantitative and qualitative data on the rocket and missile market.
This data was consolidated, enhanced with detailed inputs, analyzed by MarketsandMarkets, and presented in this report.
Bottom-Up Approach
The study analyzed the defense cybersecurity programs of multiple countries to understand various schemes and funding allocations for defense cybersecurity. After this, each program and its spending on procurement were tracked. For example, Booz Allen Hamilton Inc. (US) received an investment worth USD 1.86 Billion for the development of Zero Trust Network for the Defense Information Systems Agency (DISA), US. The above data was further refined by tracking various developments, such as contracts related to the upgrade of existing fleets, procurement of new platforms, and product development issued by the defense departments. The data sources considered for the market estimation and forecasting include the US DoD budget, cybersecurity development and integration, defense program publications, defense insights and data by SIPRI, defense expenditure of countries, and conflicts and geopolitical factors.
The bottom-up approach was employed to arrive at the overall size of the defense cybersecurity market from the revenues of key players and their shares in the market. Calculations based on the revenues of key players identified in the market led to the overall market size. The bottom-up approach was also implemented for data extracted from secondary research to validate the market segment revenues obtained. The market shares were then estimated for each company to verify the revenue shares used earlier in the bottom-up approach. With the data triangulation procedure and data validation through primaries, the overall parent market size and each individual market size were determined and confirmed in this study.
The bottom-up approach, employed to determine the overall size of the defense cybersecurity market, is delineated below.

Market Size Estimation Methodology: Bottom-Up Approach

Top-Down Approach
In the top-down approach, the overall size of the defense cybersecurity market was used to estimate the size of individual markets (mentioned in the market segmentation) through percentage splits obtained from secondary and primary research. The size of the most appropriate, immediate parent market was used to implement the top-down approach to calculate the sizes of specific market segments. The approach was also implemented to validate the revenues obtained for various market segments. Market share was estimated for each company to verify the revenue share used earlier in the bottom-up approach. With the data triangulation procedure and data validation through primaries, this study determined and confirmed the overall size of the parent market and each market segment. The following figure shows the overall market size estimation process employed for this study.
