Cloudflare Email Security customers using Microsoft Outlook can now enhance their data protection using our new DLP Assist capability. This application scans emails in real time as users compose them, identifying potential data loss prevention (DLP) violations, such as Social Security or credit card numbers. Administrators can instantly alert users of violations and take action downstream, whether by blocking or encrypting messages, to prevent sensitive information from leaking.

Today is the final day of Security Week 2025, and after a great week of blog posts across a variety of topics, we’re excited to share the latest on Cloudflare’s data security products. This announcement takes us to Cloudflare’s SASE platform, Cloudflare One, used by enterprise security and IT teams to manage the security of their employees, applications, and third-party tools, all in one place.

Forrester Research has recognized Cloudflare as a Leader in it's The Forrester Wave: Web Application Firewall Solutions, Q1 2025 report. This market analysis helps security and risk professionals select the right solution for their needs. According to Forrester: In this evaluation, Forrester assessed 10 Web Application Firewall (WAF) vendors across 22 criteria, including product security and vision. We believe this recognition is due to our continued investment in our product offering.

Over the years, we have framed our Application Security features against market-defined product groupings such as Web Application Firewall (WAF), DDoS Mitigation, Bot Management, API Security (API Shield), Client Side Security (Page Shield), and so forth. This has led to unnecessary artificial separation of what is, under the hood, a well-integrated single platform.

Generative AI is reshaping many aspects of our lives, from how we work and learn, to how we play and interact. Given that it's Security Week, it's a good time to think about some of the unintended consequences of this information revolution and the role that we play in bringing them about.

Imagine building an LLM-powered assistant trained on your developer documentation and some internal guides to quickly help customers, reduce support workload, and improve user experience. Sounds great, right? But what if sensitive data, such as employee details or internal discussions, is included in the data used to train the LLM?

AI is transforming businesses — from automated agents performing background workflows, to improved search, to easier access and summarization of knowledge. While we are still early in what is likely going to be a substantial shift in how the world operates, two things are clear: the Internet, and how we interact with it, will change, and the boundaries of security and data privacy have never been more difficult to trace, making security an important topic in this shift.
