Host Based IDS

Hello,

I am currently evaluating several host-based Intrusion Detection
Systems to monitor servers in a DMZ. My company only wants to monitor
for suspecious behaviour on critical servers, without the need for a
company wide security system. I am not interested in a network-bases
ids because this is already covered by our company.
The list below contains my findings so far;

OSSEC
Open Source Tripwire
SAMHAIN
OSIRIS
AIDE
Third Brigade Deep Security
Symantec Critical System Protection
IBM Proventia
Enterasys Dragon IDS/IPS
McAfee Total Protection for Endpoint
CA Host-Based Intrusion Prevention System r8
GFiEventsManager
Cisco Security Agent

I am thinking of suggesting OSSEC. Does anyone have any other suggestions?

Thanks in advance.

Kind regards,

Babel Timon
