RSS feed for this sectionMaking Application Security simple with a new unified dashboard experience
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. This separation, […]

HTTPS-only for Cloudflare APIs: shutting the door on cleartext traffic
Connections made over cleartext HTTP ports risk exposing sensitive information because the data is transmitted unencrypted and can be intercepted by network intermediaries, such as ISPs, Wi-Fi hotspot providers, or malicious actors on the same network. It’s common for servers to either redirect or return a 403 (Forbidden) response to close the HTTP connection and […]

Cloudflare for AI: supporting AI adoption at scale with a security-first approach
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, […]
Take control of public AI application security with Cloudflare's Firewall for AI
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? Attackers could manipulate the assistant […]
Improved Bot Management flexibility and visibility with new high-precision heuristics
Within the Cloudflare Application Security team, every machine learning model we use is underpinned by a rich set of static rules that serve as a ground truth and a baseline comparison for how our models are performing. These are called heuristics. Our Bot Management heuristics engine has served as an important part of eight global […]
Unleashing improved context for threat actor activity with our Cloudforce One threat events platform
Today, one of the greatest challenges that cyber defenders face is analyzing detection hits from indicator feeds, which provide metadata about specific indicators of compromise (IOCs), like IP addresses, ASNs, domains, URLs, and hashes. While indicator feeds have proliferated across the threat intelligence industry, most feeds contain no contextual information about why an indicator was […]
