What’s the Cost of a Data Breach?

The 2021 IBM/Ponemon Cost of a Data Breach Report reveals that it takes an average of 287 days to detect and contain a data breach – that’s 7 days longer than in 2020. The faster your organization can detect and respond to a data breach or even security incidents, the less likely it will significantly impact your data, customer trust, reputation and potential loss in revenue. 

Our automatic, operations-centric approach to incident response, people and technology should be a fully integrated part of your security operations. In a world where a well-informed Incident Response plan and 24/7 Incident Response service can save up to 30% of the cost of a data breach, no organization should be without one.
