Testing Internet Speeds
Recently, a few of our customers have upgraded their internet connections. Wanting to test the shiny new connections and demonstrate that they were money well spent, they went to speedtest.net and were disappointed to discover that the reported speeds were unexpectedly low when the traffic was routed through their Opendium Iceni web filter. We ended up fielding a few support calls relating to this, and after some investigation discovered that the low speeds being reported were largely due to flaws in the speedtest.net application.
For effective safeguarding, it is not enough to just filter the internet. Identifying which user is responsible for each web request is extremely important, as this allows for filtering to be tuned to the individual users, and for reports to be used effectively to address abuses and concerns with the individuals involved..
What is it, why is it important and how does it work?
HTTPS decryption encompasses several mechanisms that online safety systems or web filters use to examine encrypted internet communications. The terms "SSL decryption" and "TLS decryption" are sometimes also used interchangeably.
Safeguarding students is incredibly important for schools. Online safety systems such as web filters are a key part of any safeguarding strategy. These systems block inappropriate material, record an audit trail and report on any concerning behaviour.

Diagnosis: Slow Windows logins and roaming profiles
We were recently asked to diagnose a networking problem: the customer has a group of boarding houses that are connected back to the main school network through a microwave link. They were reporting that Windows logins worked fine at the school, but if they took a laptop to the boarding houses they were left waiting upwards of a minute to log in.

In Testing: Passive HTTPS Inspection
Over the past few years, HTTPS interception has become extremely important. Without it, online safety systems are extremely limited in their ability to filter and record auditing data regarding secure websites. The way this works is relatively straight forward: the client asks the Iceni proxy to connect to a secure web site, Iceni negotiates a secure connection with the web server, copies the web server's certificate and uses it to negotiate the secure connection with the client.
