Cost of data breaches climb to record high

Published

on

IBM Security has announced the results of a study, which found that data breaches now cost South African companies R46 million on average – the highest cost in the 6-year history of the report. Based on in-depth analysis of real-world data breaches experienced by organisations in South Africa, the study suggests that security incidents became more costly and harder to contain due to drastic operational shifts during the pandemic, with costs rising 15% for South African compared to the prior year.

Businesses were forced to quickly adapt their technology approaches last year, with many companies encouraging or requiring employees to work from home, and 60% of organisations moving further into cloud-based activities during the pandemic. The new findings released today suggest that security may have lagged behind these rapid IT changes, hindering organisations’ ability to respond to data breaches.  

The 2021 report revealed that the average time to detect and contain a data breach was at its highest in six years for organisations in South Africa – taking 237 days (184 to detect, 53 to contain). Companies who contained a breach in under 200 days were revealed to save almost R7 million – while it cost organisations R2300 per lost or stolen record on average. The study found that data breaches in the financial, industrial and services industries were most expensive by industry – costing R1548 per record.

“Organisations in South Africa are faced with a growing remote workforce which results in sensitive data moving across less controlled environments making it more vulnerable to a data breach. This increases the need to safeguard sensitive data at rest and in transit. Organisations need to double down on protecting their most valuable data – whether its customer, employee and company information – and ensure they have advanced security processes, like automation and formal incident response teams, in place”, says Sheldon Hand, Data, AI, Automation and Security Business Unit Leader for IBM Southern Africa

The annual Cost of a Data Breach Report, conducted by Ponemon Institute and sponsored and analysed by IBM Security, identified the following trends amongst South African organisations studied:

  • Remote work impact: With society leaning more heavily on digital interactions during the pandemic, companies embraced remote work and cloud as they shifted to accommodate this increasingly online world. The report found that the rapid shift to remote operations during the pandemic increased the average time to detect and contain data breaches. On average it took 214 days to identify data breaches and 52 days to contain it in organisations with more than 50% remote work adoption. 
  • Compromised credentials led to compromised data: Compromised business emails were the most common method of attack of breaches in the study – costing organisations over R71 million on average. Malicious insider attacks, social engineering and vulnerabilities in third-party software were also identified as the primary initial attack method for data breaches, with all three costing above R50 million on average.
  • Modern approaches reduced costs: The adoption of AI, encryption, Incident Response testing and cyberresilience  were the top mitigating factors shown to reduce the cost of a breach, saving companies between R2.7 million and R3.3 million compared to those who did not have significant usage of these tools.

Businesses That Modernised Had Lower Breach Costs

While certain IT shifts during the pandemic increased data breach costs, organisations who said they did not implement any digital transformation projects in order to modernise their business operations during the pandemic actually incurred higher data breach costs. The cost of a breach was R10 million higher than average at organisations that had not undergone any digital transformation due to COVID-19 in comparison to those at a mature stage.

Companies studied that adopted a zero-trust security approach were better positioned to deal with data breaches. This approach operates on the assumption that user identities or the network itself may already be compromised, and instead relies on AI and analytics to continuously validate connections between users, data and resources. South African organisations with a mature zero trust strategy had an average data breach cost of R29 million – which was R25 million lower than those who had not deployed this approach at all.

Investments in incident response teams and plans also reduced data breach costs amongst those studied. Companies with an incident response team that also tested their incident response plan managed to save R3million in the case of a data breach, while those that had put an incident response team in place, cut the average cost by R2.7 million.

Methodology

The 2021 Cost of a Data Breach Report from IBM Security and Ponemon Institute is based on in-depth analysis of real-world data breaches of 100,000 records or less, experienced by over 500 organisations worldwide between May 2020 and March 2021. The report takes into account hundreds of cost factors involved in data breach incidents, from legal, regulatory and technical activities to loss of brand equity, customers, and employee productivity.
