I do not intend to mince words here, this is the #1 threat out there - 90% of all compromises and breeches start with a phishing email. Stopping it, as an email security company, is our #1 job and I'm happy to report that initial results are stunning. Little bit of a rewind: Until now the most popular way to fight phishing and spear phishing was through "education" - there is an entire cottage industry of supposed "phishing education", testing, refreshers - and it all revolves around training people to hover over links in Outlook, what not to click, what to read. It will not surprise you that such "training" is practically worthless, but they say that a picture is worth a thousand words so here is our phishing book: - ![](https://storage.services.exchangedefender.network/exchangedefender-blog/blog/2019/07/First48-EPF-Phishing-Firewall-1024x674.png) In the 48 hours following 4th of July weekend in United States, dangerous links in the email were clicked on over 770,000 times. Without ExchangeDefender Phishing Firewall, these links would have redirected our clients to dangerous sites that likely would have lead to a compromise or a security breach. So much for training. What's even more telling is that, even with our firewall in place, 164,000 people decided to proceed to a dangerous site anyhow. **If more than 1 out of 5 clicks in your email will take you somewhere dangerous, how well is your training performing?** With ExchangeDefender Phishing Firewall we are enabling companies to setup policies, restrict access, provide intelligence as the user clicks -- and we provide logging giving you an idea who attempted to trash your organizations network. The scary truth behind phishing is that training is only useful in blatantly apparent cases - the kind that will NEVER even get to your inbox. Our SPAM filtering detects dangerous email content and filters it out before it has a chance to get to your Inbox. The stuff that we can flag as dangerous - thanks to user reporting, audits, and look-ahead scanning is far more sophisticated than anything we could pack into a SPAM filter - and it gives your users real intelligence on what they are about to click on. You cannot expect users to remember all their training and to be a web security analyst - their job is acting on the email. Our job, is making sure the emails get to them clean and free of dangerous malware. Once they click on the links in the email - we are going one step ahead - and leveraging our industry relationships (data feeds and infosec sharing of dangerous content) to make sure you know exactly what you're clicking on. Phishing is immensely profitable and far more effective than any other form of hacking - the user literally clicks and gives the hacker the keys to the network - and our ExchangeDefender Phishing Firewall helps remove the danger and reduces phishing to merely an annoyance. The numbers speak for themselves.
