Ingate Products Secure: Not Affected by Bash or Shellshock Security Issue
Ingate Systems products do not expose the Bash shell to any external usage and are therefore not affected by the widely reported Bash bug. Further the Ingate SIParator® (the SIP SBC) does not spread bash bug-related worm attacks, since SIP does not use such shell.
Ingate Products Secure:
Not Affected by Heartbleed
Security Issue
Ingate Systems products have not contained and do not contain the version of OpenSSL that is vulnerable to the widely reported Heartbleed bug.
