I tried Googling, but did not get a definitive answer. I'm looking for software or services that detect Phishing Emails. I read that some software like Norton, Kaspersky, etc. detect phishing websites, but do they detect Phishing Emails? How do you find software or services that detect Phishing Emails? Basically I want a software which can take emails as an input and tell whether an email is phishing or not. If I develop a system (algorithm) to detect phishing emails and test it with a large dataset of emails, I want to compare it with the performance of existing system.
Most email services can and do detect malware and often times phishing emails in the form of a Junk Mail service. There are standalone Exchange based services like McAfee Security for Microsoft Exchange (MSME) that you can custom tune for your environment to detect known phishing site links, etc.
I'm guessing this isn't exactly the answer you were wanting, but unfortunately when it comes to security, this is the most appropriate approach. But again, nearly all enterprise solutions either already provide some form of this security or you can install products like MSME to help weed out as much as you can.
