Security vendors Symantec and McAfee have criticized Microsoft for not providing enough kernel interoperability information about Vista. Microsoft sought to reassure them that more information would be provided, but McAfee’s lawyer struck out, claiming he saw, “little indication that Microsoft intends to live up to the promises it made last week”. Unsurprisingly, Microsoft did not stay silent, Ben Fathi, of Microsoft's security technology unit, said: "It's unfortunate that McAfee's lawyers are making these kinds of inaccurate and inflammatory statements."
Meanwhile, Sophos grabbed the opportunity to criticise their rivals, Richard Jacobs, CTO of Sophos said, “Symantec and McAfee may be struggling with HIPS because they haven't coded their solutions with high-spec Vista in mind”.
