Cloudflare Adds Live Threat Intel to WAF

2026-06-09 · cloudflare

Cloudflare announced that customers can now use live Cloudforce One threat intelligence directly inside WAF rules, turning threat indicators into real-time enforcement. The update lets security teams write rules based on attacker names, targeted industries, attack types, and threat datasets, reducing the gap between detection and mitigation.


What Happened

Cloudflare exposed new cf.intel fields inside its WAF engine so organizations can block traffic linked to known threat actors, DDoS datasets, cybercrime activity, or targeted industries. The company says these indicators are distributed globally and evaluated with negligible latency.

The Cost of Data Loss

Threat intelligence loses value when it remains trapped in dashboards while attackers move against production systems. A successful compromise can expose customer data, application secrets, and operational logs before defenders manually convert indicators into controls.

How Cold Storage Prevents This

Cold storage complements real-time blocking by preserving clean incident records, signing keys, recovery runbooks, and immutable backups outside the attack path. If web applications are breached, offline artifacts give teams trustworthy evidence and recovery material.
