Last year we partnered and sponsored the LetsEncrypt initiative. Today we’re happy to announce that we have fully integrated with them and we are now offering their free SSL Certificates to all customers who leverage the Sucuri Firewall.
We’re very excited about this integration and we have mass-enabled their certificates for all of our customers that did not have one yet. If your website is behind the Sucuri Firewall, your visitors can now reach your website via HTTPS by default. It is that easy.
Customers on our Professional, Business or Enterprise plans, can continue to use their custom certificates.
Enabling HTTP/2 For Everyone
In addition to mass enabling HTTPS on all sites, we have also enabled HTTP/2 by default. This will allow our clients to benefit from the performance boost that comes with the new protocol. We added support for HTTP/2 past November and we feel confident that best approach and experience is to enable it by default for all customers on our network.
If you are not familiar with HTTP/2, it is a new protocol that has been in development a few years, significantly improving performance for most websites. It is the future of the web, and via our network your website can take full advantage of its benefits without having to wait for your servers to be updated via your hosts or go through the laborious tasks of recompiling your web servers.
Mixed Content Warnings and Lack of HTTPS Support
There are two possible issues with mass adoption of HTTPS: Mixed content Warnings and lack of HTTPS support at the host (origin) level.
If your host does not support HTTPS, we will provide partial (client-only) SSL support, allowing us to encrypt the communication between the visitor and our edge servers, but not between us and the hosting server. Not ideal, but its a good first step in improving the data security chain.
In doing so, your website may be referencing resources via HTTP, which breaks some CSS or images. We have prepared an article on our Knowledge Base (KB) explaining how to fix mixed content warnings.

There are three configuration options to choose from in your dashboard:
Partial SSL: If your website backend does not provide HTTPS, we will proxy HTTPS->HTTP on your behalf. This is not ideal, but we are securing a very large piece of the communication chain between your customers and our network. This is the initial communication with your audience, and the most susceptible to Man in the Middle (MiTM) Attacks.
Full SSL: That’s the most secure and ideal method, we proxy via HTTPS from our edge to the hosting also running HTTPS. This ensures the communication is always encrypted in the wire.
Custom SSL: Professional plan and up, you can use your own Extended Validation (EV), wildcard or any other certificate you have.
No HTTPS: You can disable HTTPS by forcing all HTTPS traffic to be redirected to HTTP. Just go to Settings->SSL and click on HTTP-only site support.
Examples of LetsEncrypt Certificates
With SSL enabled, you will now be able to show your audience the secure padlock on your website. Additionally, they will be able to see all the details of the Certificate Authority (CA). You can find examples of this deployment on my personal site:
Thoughts behind HTTPS – Improving your Security
Even though we are providing SSL certificates to all our clients, we don’t subscribe to the idea that every website needs HTTPS enabled. The idea that this makes for a more secure web is inaccurate.
Leveraging HTTPS is an important step to secure data in transit, but that’s just one piece of the website security chain. This is why we only recommend HTTPS to webmasters that are already taking security seriously and as a final step to also protect the data in transit. Don’t be fooled, the padlock, the S in HTTPS, are not a sign of a secure website.
I also believe that the old process to generate SSL certificates was way to complicated; security should be simple to use and easily accessible. This principle is the foundation on which Sucuri was built, and projects like OSSEC were founded on. We built our WAF, and all our products, to make enterprise-level security available to every webmaster. Security should not be determined by the size of your organization, your team or your budget.
It’s for this reason that we’ve decided to become involved in the LetsEncrypt initiative, to simplify the creation process of certificates. Complexity should not be a reason that someone does not use SSL. If you would like to deploy LetsEncrypt on your local server, here is a basic guide on the process.
