For Most Organizations, a Zero-Trust Strategy Typically Addresses Half or Less of an Organization’s Environment
Gartner outlined three primary top-practice recommendations for security leaders implementing a zero-trust strategy.
Practice 1: Establish Scope for a Zero-Trust Strategy Early
To successfully implement zero-trust, organizations need to understand how much of the environment they cover, which domains are in scope and how much risk they can mitigate.
The scope of a zero-trust strategy does not typically include all of an organization’s environment. However, 16% of survey respondents said it will cover 75% or more while only 11% believe it will cover less than 10% of the organization’s environment (see Figure 1).

Seventy-nine percent of organizations that have fully or partially implemented zero-trust, have strategic metrics to measure progress, and of that 79%, 89% have metrics to measure risk.Security leaders must also keep their audience in mind when communicating these metrics. Fifty-nine percent of zero-trust initiatives are sponsored by either the CIO or CEO/president/board of directors.
“Zero-trust metrics must be tailored for the zero-trust deliverables as opposed to rehashing metrics used for other areas, such as the effectiveness of endpoint detection and response,” said Watts. “Zero-trust efforts deliver on specific outcomes – such as reduction of malware’s lateral movement on a network – often not captured by existing cybersecurity metrics.”
Practice 3: Anticipate Increases in Staffing and Costs but Not Delays
Sixty-two percent of organizations anticipate their cost will increase and 41% of organizations expect their staffing requirements will also increase as a result of a zero-trust implementation.
“The budget impacts of organizations who adopt a zero-trust strategy will vary based on the scope of the deployment as well as how robust the zero-trust strategy is early in the planning process,” said Watts. “Zero-trust initiatives inherently affect the budget as organizations take a systemic and iterative approach to mature their policies toward risk-based and adaptive controls, adding overhead to the organization’s ongoing operational burden.”
While only 35% of organizations said they encountered a failure that disrupted their zero-trust strategy implementation, organizations should have a zero-trust strategic plan outlining operational metrics and measure the effectiveness of zero-trust policies in order to minimize delays.
