In 2023, the number of data compromises in the United States stood at 3,205 cases. Meanwhile, over 353 million 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 2022, healthcare, financial services, and manufacturing were the three industry sectors that recorded most data breaches. The number of healthcare data breaches in the United States has gradually increased within the past few years. In the financial sector, data compromises increased almost twice between 2020 and 2022, while manufacturing saw an increase of more than three times in data compromise incidents. 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 average cyber attack takes 280 days to identify and contain and it costs an average of about $3.86 million to deal with properly.

During the third quarter of 2024, data breaches exposed more than 422 million records worldwide. Since the first quarter of 2020, the highest number of data records were exposed in the first quarter of 202, more than 818 million data sets. Data breaches remain among the biggest concerns of company leaders worldwide. The most common causes of sensitive information loss were operating system vulnerabilities on endpoint devices. Which industries see the most data breaches? Meanwhile, certain conditions make some industry sectors more prone to data breaches than others. According to the latest observations, the public administration experienced the highest number of data breaches between 2021 and 2022. The industry saw 495 reported data breach incidents with confirmed data loss. The second were financial institutions, with 421 data breach cases, followed by healthcare providers. Data breach cost Data breach incidents have various consequences, the most common impact being financial losses and business disruptions. As of 2023, the average data breach cost across businesses worldwide was 4.45 million U.S. dollars. Meanwhile, a leaked data record cost about 165 U.S. dollars. The United States saw the highest average breach cost globally, at 9.48 million U.S. dollars.

Data breaches cost companies and businesses a lot of money. The average cost of a data breach is $3.86 million.

The largest reported data leakage as of January 2024 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.

These cybersecurity statistics will help you understand the state of online security and give you a better idea of what it takes to protect yourself.

Did the COVID-19 pandemic really affect cybersecurity? Short answer – Yes. Cybercrime is up 600% due to COVID-19.

As of 2024, the mean number of days to identify the data breaches was 194 days, four percent less than in the previous year. The mean time companies needed to contain the breaches in 2024 was 64 days. In comparison, in 2022, it took organizations 207 days to identify and 70 days to address the data breaches.

Some industries are affected by cyber attacks more than others. These next cybersecurity statistics detail specifically who is affected by cyber-attacks and why they are.

Revenue in the cybersecurity industry worldwide reached $146.32 billion in 2022.

As of 2024, the average cost of a data breach in the United States amounted to 9.36 million U.S. dollars, down from 9.48 million U.S. dollars in the previous year. The global average cost per data breach was 4.88 million U.S. dollars in 2024. Cost of a data breach in different countries worldwide Data breaches impose a big threat for organizations globally. The monetary damage caused by data breaches has increased in many markets in the past decade. In 2023, Canada followed the U.S. by data breach costs, with an average of 5.13 million U.S. dollars. Since 2019, the average monetary damage caused by loss of sensitive information in Canada has increased notably. In the United Kingdom, the average cost of a data breach in 2024 amounted to around 4.53 million U.S. dollars, while in Germany it stood at 5.31 million U.S. dollars. The cost of data breach by industry and segment Data breach costs vary depending on the industry and segment. For the fourth consecutive year, the global healthcare sector registered the highest costs of data breach, which in 2024 amounted to about nine million U.S. dollars. Financial institutions ranked second, with an average cost of six million U.S. dollars for a data breach. Detection and escalation was the costliest segment in data breaches worldwide, with 1.63 U.S. dollars on average. The cost for lost business ranked second, while response following a breach came across as the third-costliest segment.

Pay attention to the following cybersecurity statistics to learn how to protect yourself from attacks.
