In 2018, cybersecurity remains an issue as hackers' attacks have become more sophisticated. The number of data breaches in 2017 was 44.7% higher than in 2016, with a total of 1,579 publicly disclosed data leaks. Common causes of data breaches include hacking, unauthorized access, accidental web exposure, and employee errors. Despite increased security investments, the number of breaches has not decreased due to concerns about performance impacts and lack of budget and staffing. On average, it takes companies 191 days to detect a breach.
