零信任安全架构采用动态的显式信任模型，取代传统安全架构中静态的隐式信任模型。安全和风险管理领导者须为零信任项目制定清晰的路线图，优化企业机构的风险态势。
北美和其他地区的企业机构强烈希望采用零信任安全范式，以降低自身的安全风险，但在操作层面却很难将此想法转化为可行的战略，以及确定路线图、项目和可衡量的成果。
供应商大肆宣传“零信任”，让企业机构认为可以通过采购相关产品提高安全性，但零信任并非特指某一种技术。零信任作为一种范式，会对适用于各种技术的网络安全原则进行重组和强调，以应对企业机构面临的特定风险。
如果缺乏清晰的战略和周密的规划，企业机构的技术实施可能会缺乏完整性，造成时间和资源的浪费，并可能产生错误的安全感。战略制定的常见阻碍因素包括遗留技术、可扩展性、零信任技术实施中的集成和能力差距、企业机构的内部阻力，以及未能考虑对业务流程的影响。
零信任技术的实施会产生高额的运营性间接成本，特别是在企业机构没有明确定义“谁有权访问什么”，并且没有集成技术控制以适应环境变化的情况下。
负责领导零信任项目以改善基础设施安全的安全和风险管理领导者，应：
明确具体用例，构建切实可行的零信任战略，例如通过限制恶意软件的横向移动或隔离软件供应链攻击，减少应用和服务的风险暴露，或缓解特定威胁。
对身份与访问管理（IAM）技术和流程等当前环境进行评估，解决相关风险，针对关键用例制定企业机构的零信任战略和要求，然后再投资新的零信任技术。
在项目的早期阶段，通过培养零信任思维、宣传项目对工作流和流程的预期影响，制定计划克服关键阻碍因素，如内部阻力。
在技术评估过程中，强调可管理性、部署范围以及对用户体验的潜在影响。为零信任技术管理员明确可扩展的流程和技术，并利用运营保障实践来衡量控制措施的有效性。
