Security and cybersecurity incidents are costly, with losses increasing every year. It is no wonder, then, that organizations continually rank security as a top priority for new spending. But how much are they spending? This report provides spending and staffing benchmarks by industry and organization size for IT security, cybersecurity, and related compliance. Benchmarks are calculated by number of users, organization revenue, and percentage of IT spending, as well as by number of network devices, locations, and endpoints. Security staffing is calculated as a percentage of the IT staff and also per user. Industry benchmarks are provided for business services, financial services, critical infrastructure, public sector, healthcare, manufacturing/distribution, and retail. There is also a breakdown for identity/access management, security policy/awareness, cybersecurity/incident response, threat and vulnerability management, data privacy/security, and governance, risk, and compliance.
