Data Breach Cost Companies $3.86 Million on Average in 2020: IBM Study

IBM Security announced today the results of a global study examining the financial impact of data breaches, revealing that these incidents cost companies $3.86 million per breach on average, and that compromised employee accounts were the most expensive root cause. Based on in-depth analysis of data breaches experienced by over 500 organizations worldwide, 80% of these incidents resulted in the exposure of customers’ personally identifiable information (PII). Out of all types of data exposed in these breaches, customer PII was also the costliest to businesses.

Sponsored by IBM Security and conducted by the Ponemon Institute, the 2020 Cost of a Data Breach Report is based on in-depth interviews with more than 3,200 security professional in organizations that suffered a data breach over the past year. Some of the top findings from this year’s report include:

  • Smart Tech Slashes Breach Costs in Half: Companies who had fully deployed security automation technologies (which leverage AI, analytics and automated orchestration to identify and respond to security events) experienced less than half the data breach costs compared to those who didn’t have these tools deployed – $2.45 million vs. $6.03 million on average.
  • Paying a Premium for Compromised Credentials: In incidents where attackers accessed corporate networks through the use of stolen or compromised credentials, businesses saw nearly $1 million higher data breach costs compared to the global average – reaching $4.77 million per data breach. Exploiting third-party vulnerabilities was the second costliest root cause of malicious breaches ($4.5 million) for this group.
  • Mega Breach2Costs Soar by the Millions: Breaches wherein over 50 million records were compromised saw costs jump to $392 million from $388 million the previous year. Breaches where 40 to 50 million records were exposed cost companies $364 million on average, a cost increase of $19 million compared to the 2019 report.
  • Nation State Attacks – The Most Damaging Breaches:  Data breaches believed to originate from nation state attacks were the costliest, compared to other threat actors examined in the report. State-sponsored attacks averaged $4.43 million in data breach costs, surpassing both financially motivated cybercriminals and hacktivists.

Wendi Whitmore, Vice President, IBM X-Force Threat Intelligence said  “At a time when businesses are expanding their digital footprint at an accelerated pace and security industry’s talent shortage persists, teams can be overwhelmed securing more devices, systems and data. Security automation can help resolve this burden, not only enabling a faster breach response but a significantly more cost-efficient one as well.”

Employee Credentials and Misconfigured Clouds – Attackers’ Entry Point of Choice 
Stolen or compromised credentials and cloud misconfigurations were the most common causes of a malicious breach for companies in the report, representing nearly 40% of malicious incidents.

Similarly, companies’ struggle with security complexity – a top breach cost factor – is likely contributing to cloud misconfigurations becoming a growing security challenge. The 2020 report revealed that attackers used cloud misconfigurations to breach networks nearly 20% of the time, increasing breach costs by more than half a million dollars to $4.41 million on average – making it the third most expensive initial infection vector examined in the report.

State Sponsored Attacks Strike Heaviest

Despite representing just 13% of malicious breaches studied, state-sponsored threat actors were the most damaging type of adversary according to the 2020 report, suggesting that financially motivated attacks (53%) don’t translate into higher financial losses for businesses.

Advanced Security Technologies Prove Smart for Business 
The report highlights the growing divide in breach costs between businesses implementing advanced security technologies and those lagging behind, revealing a cost-saving difference of $3.58 million for companies with fully deployed security automation versus those that have yet to deploy this type of technology. The cost gap has grown by $2 million, from a difference of $1.55 million in 2018.

Companies in the study with fully deployed security automation also reported significantly shorter response time to breaches, another key factor shown to reduce breach costs in the analysis. The report found that AI, machine learning, analytics and other forms of security automation enabled companies to respond to breaches over 27% faster than companies that have yet to deploy security automation – the latter of which require on average 74 additional days to identify and contain a breach.
Incident response (IR) preparedness also continues to heavily influence the financial aftermath of a breach.
Some additional findings from this year’s report include:

  • Remote Work Risk Will Have a Cost – With hybrid work models creating less controlled environments, the report found that 70% of companies studied that adopted telework amid the pandemic expect it will exacerbate data breach costs.
  • CISOs Faulted for Breaches, Despite Limited Decision-Making Power: Forty-six percent of respondents said the CISO/CSO is ultimately held responsible for the breach, despite only 27% stating the CISO/CSO is the security policy and technology decision-maker. The report found that appointing a CISO was associated with $145,000 cost savings versus the average cost of a breach.
  • Majority of Cyber Insured Businesses Use Claims for Third Party Fees:The report found that breaches at studied organizations with cyber insurance cost on average nearly $200,000 less than the global average of $3.86 million. In fact, of these organizations that used their cyber insurance, 51% applied it to cover third-party consulting fees and legal services, while 36% of organizations used it for victim restitution costs. Only 10% used claims to cover the cost of ransomware or extortion.
  • Regional & Industry Insights: While the U.S. continued to experience the highest data breach costs in the world, at $8.64 million on average, the report found that Scandinavia experienced the biggest year over year increase in breach costs, observing a nearly 13% rise. Healthcare continued to incur the highest average breach costs at $7.13 million — an over 10% increase compared to the 2019 study.

Prashant Bhatkal, Security Software Leader, IBM India/South Asia said: “India is witnessing a change in the nature of cyber-crimes, it is now extremely organized and collaborative with rising incidents of phishing attacks, social engineering attacks, etc. The Hybrid- work environment has further brought about a dynamic change in the way organizations look at their security posture. While companies are being aware of the importance of cyber security solutions, we witnessed a 9.4% rise from last year in the total cost of data breach. Further, those with fully deployed security automation were able to detect and contains a breach more than 27% faster than those with none.
