SecuriTeam is a free and independent computer security portal, covering both security news and the most recent threats, with a database dating back to 1998. SecuriTeam's main focus is software vulnerabilities.
SecuriTeam was founded by Aviram Jenik and Noam Rathaus and was the basis of what evolved into the security scanning vendor Beyond Security but now runs as a completely community-run project. Its most notable effort is the web portal where they notify visitors of new security vulnerabilities, tools and exploits. Another community tool SecuriTeam provides is a blogs site where notable security names such as Roger Thompson, Rob Slade and David Harley write, although most of the contributions to the site are from newer names in the security field. One such contributor is Juha-Matti Laurio who writes about new Zero day attacks as they come out in FAQ form, to end users, and Matthew Murphy who writes technical commentary and policy commentary on the issue of full disclosure.
