In the words of Sun Tzu, “Do not depend on the foe not coming, but rely on our readiness against him. Do not depend on the foe not attacking, but rely on our position that cannot be attacked.”

Data breaches are becoming a frequent occurrence every passing day. From industries ranging from hospitality, fintech, IT, healthcare, finance, and education, among others, it seems none of our personal data is as safe as we hope. So, why do breaches occur? What kind of data is compromised? What can be done to prevent such attacks? And what are the ramifications of such breaches? 

We understand if you’re left with a host of questions after reading bombastic data spill headlines. This article aims to ponder and reflect on the omnipresent digital danger of data breaches plaguing the cyber world. We have compiled some alarming data leakage statistics and security breach statistics and explain the trends observed on a global scale.


A data breach constitutes any security incident in which unauthorized parties gain access to confidential information or sensitive data, including personal data (Social Security numbers, healthcare data, bank account numbers) or corporate data (customer data records,  financial information, intellectual property).

As per a recent study conducted by IBM and the Ponemon Institute, Data breaches have an average projected cost of nearly $4 million globally. 

Data breaches commonly involve financial information like bank account or credit card details, personally identifiable information (PII), protected health information (PHI), intellectual property, or trade secrets. Other terms for data breaches include cloud leak, unintentional information disclosure, information leakage,  data leak, or a data spill. Cyber threats, cyber risks, and ransomware breaches engineered by bad actors and cybercriminals are threatening the cybersecurity landscape, leading to an increase in cyber incidents and the cost of cybercrime.

Overview of data breaches

Due to the sheer amount of information in digital form and technological advancement, data breaches have become a common occurrence. Cybercriminals or hackers largely carry out these attacks for financial gain, terrorism, politics, espionage, or other reasons. Data breaches can be costly to remedy through costs of investigation, destroy lives, potentially ruin the reputation of prominent businesses, and redress victim compensation, fines, etc.

Here are some security breach statistics:

A zero-trust architecture was not employed by 79% of critical infrastructure organizations. 

Cloud-based data breaches made up 45% of all breaches. 

At least 42 million records were compromised between March 2021 and February 2022 due to data breaches.

Hospitals make up 30% of all large data breaches.

How do Data Breaches Occur?

Here are a few main data leakage statistics involving the most frequent kinds of attacks that lead to ransomware, data breaches, and phishing. 

1. Phishing

Phishing attacks are social engineering aimed at tricking you into revealing sensitive information such as usernames or passwords.

At 16%, phishing was identified as the second most common cause of a breach and the costliest in breach costs at USD 4.91 million.

Over the course of 2018, phishing attacks grew by 250%.

As per the AICPA (2018), 26% are targeted by phishing emails out of 60% of Americans who have been exposed to fraud schemes.

Breaches caused by compromised or stolen credentials had an average cost amounting to USD 4.50 million.

2. Ransomware

Ransomware is malicious malware tailored to deny access to data or systems until a ransom is fulfilled. Phishing emails are the major cause of spreading ransomware. 

In an IBM study, 11% of breaches were identified as ransomware attacks, for a growth rate of 41%, a 7.8% increase from 2021. 

The average cost of a ransomware attack reduced slightly–  in 2021, it was USD 4.62 million as compared to USD 4.54 million in 2022.

27% of malware breaches are a result of ransomware.

Every 11 seconds in 2021, a business will fall victim to a ransomware attack.

Compared to 2019, ransomware attacks increased by 435%, and malware attacks increased by 358%.

Guarding Against Loss: Data Breach Prevention Strategies

Data breaches occur when data security and information security are compromised, resulting in personal information, sensitive information, or other sensitive data being exposed, transmitted, copied, stolen, viewed, or used by people with unauthorized access.

Some of the major causes of data breaches include:

  • A lack of general cyber security measures
  • Social engineering and phishing 
  • Cyber attacks 
  • Ransomware and other types of malware
  • Physical theft of hard drives
  • Bad information security policies
  • Poor security awareness training
  • Slow vulnerability assessment and patching cadence

To prevent data breaches, many organizations are investing in preventative measures, like third-party risk management and attack surface management.  

Let us look at a few data breach prevention statistics.

Biometric authentication is being implemented by 63% of organizations that have experienced a data breach. (Veridium)

80% of businesses planned to increase their spending on security in 2018. (451 Research)

Information security was cited by 7% as the largest budgetary increase area in 2018. (451 Research)

Worldwide information security spending in 2019 to exceed $124 billion. (Gartner)

Global IT Spending Forecast,  in 2020, to total $3.9 Trillion. (Gartner)

US President’s Budget for FY 2021 includes $18.8 Billion in Cyber Security Funding. (Whitehouse)

Information security spending forecast in 2023 to surpass $151 billion. (IDC)

Costs associated with insider threat investigations and prevention since 2017 increased by 60%. (Ponemon Institute)


As the cybersecurity landscape continues to evolve, with attackers constantly searching for new ways to breach security defences as well as steal valuable data, organizations must focus on having a strong cybersecurity posture to defend against these threats.

To safeguard against these threats, organizations must prioritize investing in robust cybersecurity defences while providing cybersecurity training to employees. This includes application mapping and microsegmentation, implementing multi-factor authentication, investing in zero trust, conducting regular security audits, and advanced threat detection and incident response tools. 

By taking these steps, organizations can safeguard themselves against the sobering data leakage statistics that we have highlighted for the coming years.
