Well, I kind of came across this link (and tool) and it has not been mentioned elsewhere it seems.

The main function of INCA Internet's "nProtect MBR Guard" is protecting from illegal tampering MBR sector of HDD and it adopted Command-Filter Driver technique to restrict "Overwrite" in that sector with fully understanding of API's in Windows.
These are minimum factors for securing integrity and protecting system. MBR sector must be protected for using computer safely.

"nProtect MBR Guard" will remain driver Layer and protect from all malicious commands. Unlike MBR, general disks such as (C:\, D:\) are mounted and can be protected with File System Filter modules.
That's the reason why "nProtect MBR Guard" adopted "Disk Filter" which is filtering Disk.sys Driver on MBR sector and understood Disk I/O flow.

P.S. I've not tried this program and I don't know whether this supports x64 (64-bit). Seems like an alternative to MBRGuard developed by BlueRidge but which is no longer offered as a stand-alone program and is incorporated into AppGuard instead.

I guess this should provide some kind of protection against bootkit that make changes to MBR.
