"Websense" is a number versions of several different products, and without knowing which one is in use, I can't say for certain what the reason is that HTTPS connections are getting through. However, there are a couple of likely candidates: 1) Some Websense software does not have HTTPS proxy capabilities. Without this ability, the Websense software cannot ...

HTTPS is more secure and limits the ability of attackers to snoop or modify your connection. The filtering seems to be configured for both security concerns and content accessing.

In the specific example you have outlined, yes, it would be possible to correlate this information to say that both IP addresses seem to be for the same user. Even without cookies, it may be possible to identify you across sessions, IP addresses, etc. For example, they could use browser fingerprinting or other techniques. If you wanted to try to reduce ...

You're not missing anything -- cookies absolutely can identify you when behind a proxy, and you absolutely can link proxy and non-proxy IPs. The catch is that proxies can have many users, so linking the IPs may not be correct -- not all connections from the proxy are from the person with that non-proxy IP address. But if you don't want a site to be able to ...

A proxy server is a server which requests websites for you. When you would like to request http://security.stackexchange.com, you don't contact stackexchange.com directly. You contact yourproxy.example.com instead, and ask it to get http://security.stackexchange.com for you. The proxy will then contact stackexchange.com with its own IP and relay the ...

Being 100% annonymous online is art itself, so let me give you some helpfull advice. What you are looking for (for masking full internet connection) is a VPN, there are loads of free VPN's out there, but beware of their orgins, there are enough free VPN's that get malware or a remote client on your PC, and it could get infected. Some good free VPN services ...

Depending on where this proxy device would hypothetically reside on your local network, it could cause unintended local congestion, interfaces errors, etc. The cloud solution would keep all this off your network.

Pros: Possibly reduced cost. You won't be maintaining your own infrastructure. Cloud solutions typically allow you to force company assets (like laptops for example) to be routed through the cloud proxy for URL filtering even when off network. (increased security) Cons: Could increase latency. This may or may not be applicable based on your ...

WhatIsMyIP does not need anything javascript-related to get your IP. Almost always your proxy will set the header X-Forwarded-For on your request. WhatIsMyIP will get your primary IP from that. Try accessing this site and see all the headers your browser sent and the headers your proxy added. If you install Firebug on Firefox, you can compare the headers ...

I agree with everything that the first person to answer your question has said -- this is likely a router DNS hack, UNLESS there is persistent malware on some other endpoint (say, your child's computer) within your local LAN (the one whose IP addresses start with "192.168" etc. etc.) that is attacking the rest of your local infrastructure faster than you can ...

What you've described sounds like your router's DNS settings have been changed to use servers under the control of your attackers. You can confirm this by disabling the proxy server. If you disable the proxy and the problem goes away then wipe the proxy machine and start again - it's the only way to be sure. You can reset the DNS server settings to what ...
