Follow changes

Atom and RSS feeds for any feed reader: CVEs newly seen on hosts in the dataset, daily exposure changes for a country or a network, and changes to this site. Refreshed hourly.

Site-wide

  • New CVEs on hosts. CVEs newly seen with current matches on hosts in the dataset, known exploited and critical first; severity, hosts with it now, first seen date. Atom · RSS
  • Changes to this site. New pages, tools and data. Atom · RSS

A country or a network

One entry per day with a change: the hosts with known CVEs and the change since the day before, and the CVEs seen there for the first time. Put any two-letter country code or network number in the address.

Country and network pages name their feed for feed readers, so pasting the page address into a reader works too.

Every network (autonomous system) ranked by its hosts with known CVEs, and a page per network with its most common CVEs, most exposed hosts, routes, upstreams and peers.

Search by address, domain name, CVE, AS number or words (a company, a brand, software and version, a vulnerability): the best match first, then networks, domains, CVEs, software and pages of this site.

Use

The feeds are free to use; attribution is appreciated. At most 30 requests a minute per client. A reader that checks once an hour is plenty: the figures change hourly at most, and the CVE matches once a day.
