隐私保护 vs. 企业监控 DLP
传统的 AI 浏览器 DLP 工具会拦截、检查并记录员工输入的所有内容——形成一道监控层。cloak.business 将控制权交还给员工：PII 在到达 AI 之前即完成匿名化，由员工决定哪些内容需要保护。
| Enterprise AI DLP | cloak.business Extension | |
|---|---|---|
| 处理方式 | 拦截并告警——由 IT 决定员工可以发送什么 | 匿名化后发送——用户掌控自己的工作流程 |
| 员工监控 | 拦截剪贴板、表单提交、文件上传、截图、USB 传输及打印操作 | 仅处理 AI 对话输入框中的文字——其他内容一概不涉及 |
| GDPR（雇主） | 员工监控需要法律依据；在多个欧盟司法管辖区受到质疑 | 不监控员工——匿名化是隐私增强工具，而非监控手段 |
| 可逆性 | 被拦截的内容将丢失；无法恢复 AI 工作流程 | 经 AES-256-GCM 加密的令牌在 AI 响应中自动解密——完整工作流程得以保留 |
| 检测方式 | 基于 AI/LLM 的分类——可能产生误报，遗漏结构化标识符 | 317 个确定性正则识别器 + NLP——结构化 ID 始终被捕获 |
| 语言支持 | 以英语为中心的机器学习模型 | 支持 48 种语言，包括 RTL 文字（阿拉伯语、希伯来语、波斯语、乌尔都语）及亚太字符集 |
| 数据存储 | 美国厂商——数据流经美国基础设施 | 德國 Falkenstein 的 ISO 27001:2022 認證伺服器 — 歐盟資料永遠不會離開歐盟 |
| 定价 | 仅限企业合同 | 免费套餐（200 个令牌/月）——无最低承诺要求 |
企业 DLP 对比基于公开记录的产品功能。实际部署情况可能有所不同。
