As more and more companies experience crippling security breaches, the wave of compromised data is on the rise. Data breach statistics show that hackers are highly motivated by money to acquire data, and that personal information is a highly valued type of data to compromise. It’s also apparent that companies are still not prepared enough for breaches even though they are becoming more commonplace.
We’ve compiled 98 data breach statistics for 2022 that also cover types of data breaches, industry-specific stats, risks, costs, as well as data breach defense and prevention resources. Hopefully, this will help organizations understand the importance of data security and how to better allocate their security budgets.

Cost of a Data Breach
It’s no secret that data breaches are costly for businesses. To calculate the average cost of a data breach, security institutes collect both the direct and indirect expenses suffered by the breached organization.
Direct expenses include forensic experts, hotline support, credit-monitoring subscriptions and potential settlements. Indirect costs include in-house investigations and communication, as well as customer turnover or diminished rates from a company’s impacted reputation after breaches. See below to find out just how expensive it is to experience a breach and what elements cause the cost to rise even more.

Historical Data Breach Statistics
Some of the biggest data breaches recorded in history are from 2005 and on. Once governments and businesses moved from paper to digital storage, data breaches became more commonplace.
In 2005 alone, there were 136 data breaches reported by the Privacy Rights Clearinghouse, and more than 4,500 data breaches have been made public since then. However, it’s reasonable to believe the actual number of data breaches is likely much higher, as some of the data breaches reported by the Privacy Rights Clearinghouse have unknown numbers of compromised records. The 2014 Verizon Data Breach Investigation alone reported 2,100 data breaches, with 700 million exposed records.

Definition of a Data Breach
A data breach is any incident in which confidential or sensitive information has been accessed without permission. Note: data does not have to have been exfiltrated from the network to be considered a breach. Breaches are the result of a cyberattack by criminals who gain unauthorized access to a computer system or network. They then steal the private, sensitive, or confidential personal and financial data of the customers or users contained within.
Common cyberattacks used in data breaches are:
The Origin of Data Breaches
Although data breaches seem more prevalent nowadays because of cloud computing and increased digital storage, they have existed as long as companies have maintained confidential information and private records. However, publicly-disclosed data breaches increased in frequency in the 1980s, and awareness of data breaches grew in the early 2000s.
According to the Office of Inadequate Security, in 1984 the global credit information corporation known as TRW (now called Experian) was hacked and 90 million records were stolen. In 1986, 16 million records were stolen from the Canada Revenue Agency.
Most public information on data breaches only dates back to 2005. In 2020, multiple surveys showed that more than half of Americans were concerned about data breaches during natural disasters, as well as personal safety resulting from the pandemic. Data breaches today tend to impact millions of consumers in just one companywide attack.
How do Data Breaches Occur?
A data breach occurs when a cybercriminal infiltrates a data source and extracts confidential information. This can be done by accessing a computer or network to steal local files or by bypassing network security remotely. While most data breaches are attributed to hacking or malware attacks, other breach methods include insider leaks, payment card fraud, loss or theft of a physical hard drive of files, and human error. The most common cyber attacks used in data breaches are outlined below.
Ransomware is software that gains and locks down access to vital data. Data is encrypted in files and systems, and a fee — commonly in the form of cryptocurrency — is demanded to regain access to them.
Common Target: Enterprise companies and businesses
Malware, commonly referred to as “malicious software,” is a term that describes any program or code that harmfully probes systems. Malware is designed to infect your computer and commonly masquerades as a warning against harmful software. The fake warning attempts to convince users to download varying types of software, and while it does not damage the physical hardware of systems, it can steal, encrypt or hijack computer functions.
Malware can penetrate your computer when you are navigating hacked websites, downloading infected files, or opening emails from a device that lacks anti-malware security.
Common Target: Individuals and businesses
Phishing scams are one of the most common ways hackers gain access to sensitive or confidential information. Phishing involves sending fraudulent emails that appear to be from a reputable company, with the goal of deceiving recipients into either clicking on a malicious link or downloading an infected attachment, usually with the intent of stealing financial or confidential information.
Common Target: Individuals and businesses
Denial of Service (DoS)
Denial of Service is a cyber attack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting the services of a host connected to the internet. It is typically accomplished by flooding the targeted machine or resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being fulfilled.
Common Target: Sites or services hosted on high-profile web servers, such as banks
Data Breach Defense + Prevention Resources
Companies need to examine lessons from the GDPR and update their data governance practices as more iterations are expected in the coming years. It’s crucial to properly set permissions on files and remove stale data.
Keeping data classification and governance up to par is instrumental to maintaining compliance with data privacy legislation like HIPAA, SOX, ISO 27001 and more. Today, modern solutions offer great protection and a more proactive approach to security to ensure the safety of sensitive information.

Data Breach Insurance Types
In order to mitigate the risk that comes along with data loss, many companies are now purchasing data breach insurance to support their data breach prevention and mitigation plans. Data breach insurance helps cover the costs associated with a data security breach. It can be used to support and protect a wide range of components, such as public relations crises, protection solutions and liability. It may also cover any legal fees accumulated from the breach.
Common types of data breach insurance are:
With many different kinds of consequences that occur due to a data breach, significant time and money will be spent to recover. From recovering data and notifying stakeholders, first-party insurance covers the following:
- Investigating costs
- Notifying all affected parties
- Fielding inquiries
- Tools to help affected parties
Third-party insurance is primarily used by contractors and IT professionals to lessen their liability. The covered expenses may include things such as the following:
- Lawyers’ fees
- Judgments and liability
- Other court costs such as witness fees, docket fees, etc.
