The worst part of Web 2.0 is the elevated amount of Spam. Several times per day, I get an invite to a new social network (or website) from someone I don't even know. Add phishing emails. Add scam emails. Add viagra emails. Add replica rolex watch emails. At the height of the Web 2.0 craze, I was getting tens of thousands of emails per month. Perimetec is headquartered in Toronto, Ontario and offers Email Spam Protection. They can eliminate email spam inside your organization with Perimetec's Barracuda Spam firewall. This is a hardware firewall sitting between the Internet and your email gateway. Junk and spam email are discarded before they even find your email server. Questionable emails are quarantined. Quarantined emails can then be forwarded to the destination email address and the sender can be whitelisted to prevent future emails from also being quarantined. Barracuda uses 12 separate defense layers; Denial of Service (DoS) and Security Protection, Rate Controls, IP Reputation Analysis, Sender Authentication, Recipient Verification, Virus Protection, Policy (user-specified rules), Fingerprint Analysis, Intent Analysis, Image Analysis, Bayesian Analysis, and a Spam Rules Scoring engine.
