We got notified by couple of readers that Finjan's appliance started blocking access to isc.sans.org due to detected malicious behavior, whichi s a false positive. The URL analysis tool on the Finjan's web site confirms that this is indeed happening.

We notified Finjan and this should be fixed as soon as possible. In the mean time, you can put isc.sans.org on the white list so you can continue visiting us.

UPDATE

This has been fixed, thanks to fast support from Finjan.
