Security Week is an initiative by Cloudflare to emphasize the importance of cybersecurity and announce new product enhancements, partnerships, and features. The company has been working on various aspects of security, including protecting websites, managing automated traffic, securing non-HTTP traffic, and developing a forward proxy security strategy with its Zero Trust platform. With the increasing threat landscape, Cloudflare aims to make security more accessible and integrated into its network services while partnering with other cybersecurity companies for better user experience.
