保护企业中使用的所有应用，包括现代云原生应用、传统私有应用和 SaaS 应用。其中包括使用动态端口的应用和利用服务器启动连接的应用。 如今，工作不再意味着上班打卡，而是一种比较灵活的活动。在疫情最严重的时候，许多企业都尝试扩展其 VPN 基础设施。当这一策略不起作用时，他们立即将目光转向 ZTNA 1.0 解决方案，结果发现也无法达到预期结果。ZTNA 2.0 是克服 ZTNA 1.0 现有局限性所必需的模式转变，是长期为您企业提供支持的正确架构。 [请于 6 月 15 日参加活动](https://start.paloaltonetworks.com/zero-trust-with-zero-exceptions)，届时我将更深入地介绍 Prisma Access 的 ZTNA 2.0 如何为混合劳动力提供保护。 *** ** * ** *** ## Related Blogs ### [Announcement](https://www.paloaltonetworks.com/blog/category/announcement-zh-hans/?lang=zh-hans&ts=markdown), [Products and Services](https://www.paloaltonetworks.com/blog/category/products-and-services-zh-hans/?lang=zh-hans&ts=markdown) [#### Palo Alto Networks 以量子安全与多云防护引领未来](https://origin-researchcenter.paloaltonetworks.com/blog/2025/09/paves-way-for-quantum-ready-security/?lang=zh-hans) ### [Announcement](https://www.paloaltonetworks.com/blog/category/announcement-zh-hans/?lang=zh-hans&ts=markdown), [Products and Services](https://www.paloaltonetworks.com/blog/category/products-and-services-zh-hans/?lang=zh-hans&ts=markdown) [#### 从根本上简化网络安全](https://origin-researchcenter.paloaltonetworks.com/blog/2024/11/ai-copilot-simplified-security/?lang=zh-hans) ### [Announcement](https://www.paloaltonetworks.com/blog/category/announcement-zh-hans/?lang=zh-hans&ts=markdown), [News and Events](https://www.paloaltonetworks.com/blog/security-operations/category/news-and-events-zh-hans/?lang=zh-hans&ts=markdown), [Products and Services](https://www.paloaltonetworks.com/blog/category/products-and-services-zh-hans/?lang=zh-hans&ts=markdown) [#### Forrester 将 Palo Alto Networks 评为攻击面管理的领导者](https://origin-researchcenter.paloaltonetworks.com/blog/2024/10/forrester-names-palo-alto-networks-a-leader-in-attack-surface-management/?lang=zh-hans) ### [Announcement](https://www.paloaltonetworks.com/blog/category/announcement-zh-hans/?lang=zh-hans&ts=markdown), [Must-Read Articles](https://www.paloaltonetworks.com/blog/security-operations/category/must-read-articles-zh-hans/?lang=zh-hans&ts=markdown), [News and Events](https://www.paloaltonetworks.com/blog/security-operations/category/news-and-events-zh-hans/?lang=zh-hans&ts=markdown), [Product Features](https://www.paloaltonetworks.com/blog/security-operations/category/product-features-zh-hans/?lang=zh-hans&ts=markdown), [Products and Services](https://www.paloaltonetworks.com/blog/category/products-and-services-zh-hans/?lang=zh-hans&ts=markdown) [#### Forrester 将 Palo Alto Networks 评为 XDR 领域的领导者](https://origin-researchcenter.paloaltonetworks.com/blog/2024/07/forrester-names-palo-alto-networks-a-leader-in-xdr/?lang=zh-hans) ### [Announcement](https://www.paloaltonetworks.com/blog/category/announcement-zh-hans/?lang=zh-hans&ts=markdown), [Products and Services](https://www.paloaltonetworks.com/blog/category/products-and-services-zh-hans/?lang=zh-hans&ts=markdown) [#### 测试防火墙性能和灵活性的极限](https://origin-researchcenter.paloaltonetworks.com/blog/2023/12/firewall-performance-and-flexibility/?lang=zh-hans) ### [Announcement](https://www.paloaltonetworks.com/blog/category/announcement-zh-hans/?lang=zh-hans&ts=markdown), [Products and Services](https://www.paloaltonetworks.com/blog/category/products-and-services-zh-hans/?lang=zh-hans&ts=markdown) [#### Prisma Cloud：达尔文版本首次引入代码到云智能](https://origin-researchcenter.paloaltonetworks.com/blog/2023/12/announcing-innovations-cnapp-prisma-cloud/?lang=zh-hans) ### Subscribe to the Blog!
