Websites and APIs stay up, and common web attacks are filtered before they reach them.

What it is

A protective layer in front of websites and APIs that absorbs denial-of-service floods and blocks injection attacks, bots and abuse.

How to value it

DDoS attacks by hacktivists against European organisations are a recurring news item, and an hour of downtime for a customer-facing site has a direct cost. A web application firewall also buys time when a flaw in a web application is published before you can patch it.

Questions to ask a vendor

  1. 1What is the mitigation capacity, and is DDoS protection unmetered?
  2. 2How fast can you deploy a virtual patch for a new vulnerability?
  3. 3Does it protect APIs as well as websites?
  4. 4Where is traffic inspected, and what does that mean for data residency?

How we list vendors

  • A product is listed because it provides the control. Nobody pays to be listed, and on story pages the examples rotate, so no vendor is always first.
  • Vendor pages show both the vendor's own research and the incidents involving its products, from our own coverage. We do not leave either out.
  • Our summaries are written by us, based on the vendors' own pages. Text in quotation marks or marked "in their own words" is the vendor's own, quoted from its website.
  • Logos, product names and quoted text belong to the vendors and are shown to identify them.
  • Something wrong? Use "Suggest a correction" on the vendor's page. A product we should look at? Email support@threatnoir.com.
