Back in November we discussed evidence we had found that indicated that the web security company SiteLock’s TrueSpeed CDN and TrueShield Web Application Firewall services were actually provided by another company Incapsula, while SiteLock made it sound like they are providing them directly. At the time we mentioned that is “troubling as all of the customer’s website’s traffic is going to be running through a company that they don’t have a relationship with or are even likely to know is involved”. It is also troubling to think that a security company would be lying to their customers like that, since a big part of security is trust. If they are lying about something like this, where we don’t see why they even would need to, you reasonably have to wonder if there is something they wouldn’t be willing to lie about.
A recent post on SiteLock’s blog provided further confirmation that these services are actually provided by Incapsula while at the same time making it sound like SiteLock is providing them directly. In the December 18 post SiteLock TrueShield Updates they let their customers know of new IP addresses being used by those services that some of their customers would need to whitelist. Those IP addresses are
In the post there is no mention of Incapsula, but they is plenty that would make you think that SiteLock is actually providing the services. In a large font they refer to the IP addresses being used by the services as “ours”:
If you are adding our IP addresses for the *FIRST TIME*
In explaining why the new IP addresses are being added they mention their servers and IP address, despite those pretty clearly being Incapsula’s instead (emphasis ours):
The SiteLock servers periodically make requests for updated content from your website’s hosting server. This ensures that we are delivering the freshest content to your visitors. During periods of high traffic, we may make more frequent requests for content than during off-peak periods. Cloud technology of this kind uses a finite number of unique IP addresses to fulfill these requests, making this behavior appear as a security threat to some firewall services. This can be due to the large number of requests from a disproportionately low number of perceived unique visitors. Whitelisting or creating firewall exceptions for our servers’ IP addresses prevents your other security systems from blocking legitimate traffic relayed through our servers.
If we were not already familiar with a litany issues with SiteLock (you can see some of those by looking over our previous post about them) we would say this would be a good reason to avoid them, but with all the others you should have more reasons to avoid them then you should possibly need.
