Product: IPS 5500-1000
As a rate-based IPS, Top Layer is clearly top notch. Integrating signature-based IPS into the product was clearly a wise move for Top Layer, but the signature-based IPS capabilities are just not on par with the rate-based IPS — at least at this time.
While Top Layer has a mature product with an excellent management interface, the vendor hasn’t quite filled out the signature-based IPS part of its product to be as full-featured and flexible as the rate-based part. Nevertheless, the IPS 5500-1000 is still an outstanding IPS and would be a powerful security tool in an enterprise arsenal, especially used in front of server farms and other high-volume, static environments.
The IPS 5500 was among the fastest performers in our tests with one and two port pairs. It delivered essentially line-rate performance in baseline tests with TCP and UDP alike. However, forwarding rates dropped and latency rose when we subjected the system to heavy attack.The IPS 5500 also leaked a small amount of attack traffic, but the vendor attributes that to a misconfiguration on its part in firewall policy.
