ThreatLabZ, the research arm of cloud security vendor Zscaler, is rolling out a free tool IT shops can use to analyze their particular web risks. Called Zulu, this new service is the most comprehensive of its kind, pulling data from website content, URL, host, and multiple threat sources. It also provides historical scores, showing when sites were first compromised or cleaned-up. Zulu results are always in real-time (never static), providing the user with the best possible data.”]
