In 2024, the number of data compromises in the United States stood at 3,158 cases. Meanwhile, over 1.35 billion individuals were affected in the same year by data compromises, including data breaches, leakage, and exposure. While these are three different events, they have one thing in common. As a result of all three incidents, the sensitive data is accessed by an unauthorized threat actor. Industries most vulnerable to data breaches Some industry sectors usually see more significant cases of private data violations than others. This is determined by the type and volume of the personal information organizations of these sectors store. In 2024 the financial services, healthcare, and professional services were the three industry sectors that recorded most data breaches. Overall, the number of healthcare data breaches in some industry sectors in the United States has gradually increased within the past few years. However, some sectors saw decrease. Largest data exposures worldwide In 2020, an adult streaming website, CAM4, experienced a leakage of nearly 11 billion records. This, by far, is the most extensive reported data leakage. This case, though, is unique because cyber security researchers found the vulnerability before the cyber criminals. The second-largest data breach is the Yahoo data breach, dating back to 2013. The company first reported about one billion exposed records, then later, in 2017, came up with an updated number of leaked records, which was three billion. In March 2018, the third biggest data breach happened, involving India’s national identification database Aadhaar. As a result of this incident, over 1.1 billion records were exposed.

The largest reported data leakage as of January 2025 was the Cam4 data breach in March 2020, which exposed more than 10 billion data records. The second-largest data breach in history so far, the Yahoo data breach, occurred in 2013. The company initially reported about one billion exposed data records, but after an investigation, the company updated the number, revealing that three billion accounts were affected. The National Public Data Breach was announced in August 2024. The incident became public when personally identifiable information of individuals became available for sale on the dark web. Overall, the security professionals estimate the leakage of nearly three billion personal records. The next significant data leakage was the March 2018 security breach of India's national ID database, Aadhaar, with over 1.1 billion records exposed. This included biometric information such as identification numbers and fingerprint scans, which could be used to open bank accounts and receive financial aid, among other government services.

Cybercrime - the dark side of digitalization As the world continues its journey into the digital age, corporations and governments across the globe have been increasing their reliance on technology to collect, analyze and store personal data. This, in turn, has led to a rise in the number of cyber crimes, ranging from minor breaches to global-scale attacks impacting billions of users – such as in the case of Yahoo. Within the U.S. alone, 1802 cases of data compromise were reported in 2022. This was a marked increase from the 447 cases reported a decade prior. The high price of data protection As of 2022, the average cost of a single data breach across all industries worldwide stood at around 4.35 million U.S. dollars. This was found to be most costly in the healthcare sector, with each leak reported to have cost the affected party a hefty 10.1 million U.S. dollars. The financial segment followed closely behind. Here, each breach resulted in a loss of approximately 6 million U.S. dollars - 1.5 million more than the global average.

Market Dynamics of Cloud Security Market:

Key drivers of Cloud Security Market

Data breaches and cyberattacks are driving the cloud security market's rapid growth.

Due to digitalization and technological advancements, the use of the Internet is increasing in all sectors. As the use of the Internet increases, the chances of cyber-attacks increase. There is a large scale of cyberattacks that is causing the loss of private, business, and governmental data all around the world when individuals utilize the Internet to conduct focused, politically driven attacks against cloud IT infrastructure. A cyberattack that targets off-site service platforms that use their cloud architecture to provide computing, storage, or hosting services might be categorized as a cloud cyberattack. This can involve assaults on service platforms that make use of SaaS(software as a service), IaaS (infrastructure as a service), and PaaS (platform as a service) service delivery paradigms. For Example, In March 2020, a cloud cyber assault targeted the adult live-streaming website CAM4, exposing 10.8 billion confidential entries totaling 7 TB of data. Location information, email addresses, IP addresses, payment logs, usernames, and more were all included in the compromised database. (Source:https://cisomag.com/adult-website-data-leak/) The growing number of organizational data breaches and leaks is driving the cloud security market. Data in the cloud is more vulnerable to hackers than data on corporate computers. For Instance, Microsoft revealed in 2020, that in December 2019 breach in one of their cloud databases exposed 250 million entries, including IP addresses, email addresses, and support case information. The computer giant claims that a poorly designed network server that was storing the important data was the root cause of this data breach. Despite not being the largest, the high-profile target made it one of the most startling clouds cyberattacks. (Source:https://www.forbes.com/sites/daveywinder/2020/01/22/microsoft-security-shocker-as-250-million-customer-records-exposed-online/?sh=693f59f04d1b)Thus, The cloud service model enhances the dangers and security challenges associated with cloud computing systems by exposing information and offering customers a variety of services. Data loss in cloud computing is a basic security issue. Hackers from both inside and external staff may gain unauthorized or purposeful access to the data. Such setups can be targets for external hackers who utilize hacking tactics like eavesdropping and hijacking to get access to databases. Additionally, malicious programs like Trojan horses which are a kind of malicious software that infiltrates a computer under the guise of an authentic application, and viruses are added to cloud services. Therefore, to put in place a system with stronger security features, it is vital to detect potential cloud risks and protect against such breaches with good cloud security.

The market for cloud security is growing because of the emergence of DevSecOps.

As more businesses shift their apps and IT infrastructure to the cloud, cloud security is becoming more and more crucial. DevSecOps which is development, security, and operation automation is becoming popular among many enterprises as a means of guaranteeing the best possible cloud security. DevSecOps automation incorporates security into every phase of the development lifecycle, from code generation to deployment and maintenance. DevSecOps helps ...
