Earlier this month we enabled free SSL certificates for all customers to much applause and today we have another powerful new security feature to unveil to help protect your websites.
Imunify360 is an advanced firewall developed by our operating system vendor, CloudLinux.
Website attacks have become incredibly sophisticated. We used to be able to easily block brute force attacks by identifying that a visitor has submitted an incorrect password too many times in a short period. Today it is much harder to block these types of attacks as hackers no longer use a single machine but employ massive botnets of hundreds of thousands of infected computers to conduct attacks. Rather than seeing failed login attempts repeatedly coming from a single IP address, we now only see one or two login attempts before the attack switches to a different IP address. This makes it very hard to distinguish legitimate users from hackers and to prevent these attacks from reaching your website since the attacker’s IP address constantly changes every few seconds.
Imunify360 steps in by providing information on botnets and where these attacks are coming from. It uses herd immunity and artificial intelligence to detect new threats and protect all servers running the software. When one server is under attack it can alert other servers, protecting them before the threat ever reaches them.
We’ve been beta testing Imunify360 for several months and have found that our server load has been significantly reduced since we no longer have the overhead of serving websites to these bad visitors and botnets. This means your websites will even load faster as a result!
Now let’s say you’ve legitimately forgot your password and found yourself blocked by our firewall and are now unable to access your website or email. Imunify360 also helps by providing a self-service unblocking tool our customers can use to unblock their IP address without needing to contact our support department.
If you are ever presented with the above page when attempting to visit your website you can simply click the “I’m not a robot” checkbox at the bottom of the page to unblock your IP and proceed to your website.
