A question that is often raised in the windows driver community, is which vendor’s certificate works for signing kernel mode drivers in 64-bit Vista/2008. Many times certificate vendor websites and their support personnel are unaware of the windows kernel mode code signing requirements and may misguide companies into buying wrong type of certificate. If it is a small startup, it is all the more essential to get this right price-wise. So I did some poking around and here is what I found.
| Verisign | Verizon | GlobalSign | |
| Price/Year | $499 | $229 | $229 |
| Pros | May work with WHQL submissions | Cheaper | Cheaper |
| Cons | Expensive | May not work with WHQL without an additional corporate certificate. | May not work with WHQL without an additional corporate certificate. |
| Notes | Site is well organized and clarifies well what the certificate is for. | The site URL and contents suggest that this is very disorganized at the moment. | Site is well organized and clarifies well what the certificate is for. |
