2018: Data Privacy and New Regulations Take Center Stage

2018 BLI First Half Report

A number of important data breach trends emerged in the first half of 2018. One of the most notable of these developments was the introduction of new data protection regulations including the European Union's General Data Protection Regulation (GDPR), New York's Cybersecurity Requirements for Financial Services Companies and Australia's Notifiable Data Breach (NDB) scheme. The rationale behind passing these standards is to help organizations better protect customers' privacy and security by design. In terms of data breach sources, malicious outsiders and accidental loss were at the top of the list in the first half of 2018. Those forces accounted for some of the biggest security incidents.

Overall, the total number of records compromised in the first half of 2018 was 3,353,172,708. That figure marks an increase of 72 percent over H1 2017. Not surprisingly, the amounts of records breached every day, hour, minute and second also surpassed the totals observed a year earlier. What is remarkable is that all of these figures almost doubled between 2017 and 2018. Surprisingly, there were just 944 security incidents reported in the first half of 2018. That's 18 percent fewer than the 1,162 breaches disclosed in H1 2017. Of those incidents, there were just 21 data breaches where encryption was reportedly used on the data in whole or in part, less than half the figure for the previous year.

Industry Breach Details

From an industry perspective, social media witnessed the greatest number of compromised records in H1 2018 at 2.5 billion. That's a massive increase from the previous year. There were a few other industries where the number of breached accounts increased by more than a thousand percent: Industrial saw the highest growth rate, while retail and professional services also had big increases. Other sectors experienced more modest growth in either the number of compromised records or security incidents. Those included hospitality, technology, and insurance. During the same reporting period, Healthcare declined in both the number of security incidents and breached records. Organizations in government, education, entertainment, financial services and the non-profit sector all saw between 50 percent and 100 percent fewer breached records in H1 2018.

Secure the Breach

This brief video will introduce a new perspective in accepting that a breach will happen; we call this Breach Acceptance. When companies adopt the Secure the Breach mindset, they will fundamentally change the way they protect their organization by securing the real target of attacks -- the data -- rather than securing the vector.

Breach Risk Calculator

BLI Risk Calculator

How bad might a breach be if it did happen to you? Calculate your own risk score and breach severity using the Breach Level Index. Provide a few inputs as to the number of records that could be affected, and the type and source of breach possibilities. The score is calculated based on these factors, and how the stolen information was used. The point of the scoring system is to demonstrate that not all breaches have the same impact on organizations or the same amount of risk. Use your score to gauge the breach severity and see how to your organization can better prepare for a breach.

Calculate Your Score


Breaches are no longer a binary proposition where an organization either has or hasn't been breached. Instead they are wildly variable — having varying degrees of fallout — from breaches compromising entire global networks of highly sensitive data to others having little to no impact whatsoever.

The Breach Level Index not only tracks publicly disclosed breaches, but also allows organizations to do their own risk assessment based on a few simple inputs that will calculate their risk score, overall breach severity level, and summarize actions IT can take to reduce the risk score.
