But what if you knew which products to install to increase your spam blockage rate? InformationWeek's survey of more than 500 companies highlights various approaches. On average, companies typically block or intercept about half of the spam E-mail coming over the transom. Of course, that means nearly half the companies aren't achieving those results. Based on our research, 17% of sites block less than 25% of inbound spam.
We want to show you what's working for the companies experiencing some success--and also what the struggling companies are doing--so you can figure out if your company is on the right track.
First, we begin with a list of the techniques and methods applied by companies that are struggling to succeed:
Next, here's a chart showing what techniques and methods the more successful spam blockers are deploying to achieve a modicum of success:
It appears that the more tools and products a company has installed, the greater percentage of spam is blocked. In an ideal situation, where budgets are unlimited, all these tools and products are deployed. However, if budgets are limited, there are five tools that are "must-haves," including virus filtering, blacklists, spam filtering, content filtering, and keyword filtering. Once you have those five installed, you can increase your spam blockage rate by 10% or more if you add attachment filtering and rules-based filtering.
