Hello
I was testing SEP 12.1.5 unmanged client and tried the anti-pishing test at http://www.amtso.org/check-desktop
The page loads, SEP did not detect the page as phising. And further looking into the matter, we figured out SEP does not have anti-phishing function in its said suite. This is something which symantec certainly needs to look upon and bring in its future release/ version. Phishing is one of the major concers for firms operating in regulated environment, and not having that feature embeded in the security solution could be a major security flaw.
Recent case would be Sony; wherein, hackers were able to bypass security network and soon whole network got compromised.
