Market Size for Cybersecurity service in 2026 [Example]

The total available market (TAM) for cybersecurity services includes small businesses, enterprises, and individual consumers worldwide. With approximately 1.5 billion potential users connected to the internet, and considering the average annual cybersecurity expenditure per organization and individual around $100, the TAM can be estimated to be around $150 billion.

This encompasses a wide range of demographics from small businesses to large enterprises, as well as consumers who invest in personal cybersecurity solutions. Thus, the TAM reflects a holistic view of all potential customers interacting with relevant cybersecurity services globally.

The serviceable addressable market (SAM) focuses specifically on small and medium-sized enterprises (SMEs) that require cybersecurity services within the global landscape. SMEs comprise around 5% of the total internet-connected businesses, leading to a more targeted scope of approximately 75 million potential customers.

Assuming an average yearly spending of $100 per SME on cybersecurity services, the SAM is calculated at around $7.5 billion. This figure realistically represents the segment of the market that a solopreneur in the cybersecurity space can effectively reach given constraints such as business scale and geographical reach.

The serviceable obtainable market (SOM) further narrows down to the portion of the SAM that can be captured in the first year of operations. For a solopreneur starting a cybersecurity service, it’s feasible to capture around 0.01% to 1% of the SAM depending on marketing effectiveness and service delivery.

If we take a conservative estimate and target 0.1% of the SAM, this results in approximately 7,500 customers. With an average spending of $100 per customer in the first year, the SOM would equate to about $750,000, reflecting a realistic outcome for market penetration in the initial stages of the business.
