Certificate No Longer Required

As we have moved from a limited test environment to the campus-wide production environment with our new internet filter, it is no longer necessary to download the Fortigate certificate. We have made the necessary adjustments to the configuration of the filter to eliminate this requirement. If you have already downloaded the certificate, you may delete it if you would like to do so.  The new filter maintains the same capabilities and protections the campus community has been accustomed to over the years (and no more) while affording the capacity for much greater bandwidth speeds for our users.  Thank you for your patience as we continue to fine-tune our network.
