    The site verification (logo) technology is unknown to the community, in which case some security experts tend to speak of security trough obscurity. Moreover, Comodo Verification Engine only works with sites which have registered themselves in the ID Authority database;, for instance, cannot be verified. Other sites only have some, but not all pages verified by Comodo.

    On the positive side we note that the Verification Engine receives and install updates automatically to protect users from phishing attacks. Moreover, Comodo promises protection against pharming attacks trough IPVerify technology.

    The Comodo Verification Engine only verifies logos or brands made known to its database. On the other hand does the software then protect against pharming attacks. Thus, the Verification Engine and the AVG (free) Link Scanner are perfectly complementary, and compatible. Why not run them together as a best practice?
