One of the most important steps in website security is to use services that monitor internet threats and make them visible. In other words, you need to pay attention to what's happening on the Web outside your environment. These days, there are so many ways for attackers (malware authors) to compromise computers. In fact, it's hard for even the best security professionals to stay on top of everything.
The good news is that there are plenty of tools available for free or cheap that can help you manage risk. Use Quttera's ThreatSign platform for more comprehensive scanning. It will allow you to discover if Google Safe Browsing has
blocked any domains before they make it into your environment. By comparing DNS records with those provided by these services, you can also detect malware droppers associated with known compromises elsewhere on the Web—which could indicate something suspicious in your organization.
