Inside-Out protects from all threats
There are 3 primary ways malicious users will try to get to your data:

* Network-based attacks, including those from applications
* Host-based attacks, from users directly logged into the database server, or from virtual machine to virtual machine on the same physical server
* Intra-DB attacks, using sophisticated exploits based on stored procedures, triggers, and views

By monitoring the actual data structures and the execution plan as the database is accessed, Sentrigo’s memory-based sensors catch all three types of threats, with a single, non-intrusive solution. Network-based solutions see only the first type of threat, and often add a host-based agent to send local traffic to the server to catch the second (more on the inefficiencies of this approach, and systems impact, below). But, they entirely miss attacks coming from within the database, and will also miss obfuscated attacks that may look harmless, but once they are decoded at execution are in fact quite dangerous.

The bottom line is that being “inside” is the ONLY way to cover threats from all 3 sources.
