The company was once called araksha. Their technology is good (think compiler
optimization foo) but not a silver bullet. Many of the problems and issues with this
approach can be found in a paper published a couple of years ago at usenix security.
Google for it through the MIT profs name.

Subject:[SC-L] Determina claims 100% protection against all buffer overflows
Startup Determina has released a product that they claim protects
against 100% of all memory based attacks, including all types of buffer
overflows, without any false positives, false negatives or noticeable
This is appareantly based on work done by their CTO, Dr. Saman
Amarasinghe, who is an Associate Professor of the Department of
Electrical Engineering and Computer Science at MIT.
If this is based on work from MIT I guess the research should be public,
but I have trouble finding evidence that support these broad claims.

The paper gives some graphs about jump points and break instructions. I
would guess that they have a rootkit that hooks all kernel and user
space functions that deal with memory allocation and process creation.
When a process is created they probably generate a map of all
carry/jump/break instructions which they use to compare with once
anything in the system tries to alter the process memory space through
the system functions they are proxying. If anything tries to change the
existing execution roadmap they just disregard that request for a
process memory change.
