Disclaimer
This product decreases security risks. NEC does not guarantee the elimination of all of the security risks.
Due to the characteristics of this product, the following events might occur.
This product regularly updates the signature (information on the virus definition, etc.). The signature, in order to
keep the performance of this product, deletes the old pattern that has become a low risk threat when a new
pattern is added. For example, events such as intercepted traffic passes through or the traffic that passed
through is intercepted. Moreover, because the application blocked by APG is deleted from the scanned target, the
traffic of the application will be permitted in this case. In addition, blocking may not be permitted in the
Application Guard (APG) due to specification changes of the application.
This product manages terminal information (such as computers that have been set under the LAN port of this
product), and observes the traffic of each terminal. Therefore, the processing performance of this product might
decrease when the number of terminals increases.
