Close your eyes and visualize your website. The hours invested in designing it taking into account SEO, UX, UI, responsive, that it does not look like those of the competition. Hours uploading the product catalog to the ecommerce, a thousand tests of the shopping platform and the payment gateway. Now, move to the times of highest traffic on your website: launches, sales, offers, special days… What if after all this work, on the day you can least afford to fail, your website goes down and you start losing the best sales of the year?
Ah, you don’t have an ecommerce, but you do have a website full to the brim with information and traffic that is increasing, with not inconsiderable peaks. Many pages with a very well studied infrastructure so that no link fails and the user quickly finds what he is looking for. Videos, images, links, redirects? A lot of money invested in positioning your website among the first ones in Google. And a huge work of your IT department that has already begun to detect suspicious traffic. How much are you willing to lose if a cryptolocker decides to enter your website and spoil all the work?
The solution is called CDN/WAF: content delivery network + web application firewall. With this combination, we get the best of both elements and achieve speed and security for the web.
CDN is the linchpin of the Internet infrastructure of the future
CDNs (Content Delivery Network) are a set of servers spread around the world that distribute static (and even dynamic) web content quickly and efficiently with the main objective of improving the loading speed of web pages, reducing latency and making the browsing experience as smooth as possible.
Based on content replication, CDNs allow the distribution network to identify the geographic location of the user when the user requests a web page, providing the content from the nearest server, thus shortening the distance the information has to travel and, therefore, improving page loading speed.
Another added value of CDNs is that they cache content, which reduces overhead and further improves page loading speed, so that when a user wants to access a web page, they can get it directly from the cache without having to access the original server.
Does your website have high traffic? Or maybe you serve content to users all over the world? Do some of your campaigns respond to names like Black Friday, Christmas or Influencer Marketing? Then a CDN is especially useful for you. Do like Facebook, Google or Amazon, who already use CDNs to improve their users’ experience: More speed and better performance for your website.
WAF, protection for all your connections
WAF (or Web Application Firewall) is a web firewall that protects web applications from malicious attacks by analyzing incoming traffic and blocking suspicious traffic before it reaches the web application, thus protecting them from attacks such as SQL injection, cross-site scripting (XSS) and cross-site request forgery (CSRF). They also protect against denial-of-service (DoS) attacks, as they can detect and block suspicious traffic that is generating such an attack.
The main advantages of WAFs are the additional protection they offer to web applications, as well as the ability to detect and block attacks in real time, and they are also a useful solution for application developers, who can use WAF activity logs to detect errors and security problems in their applications.
At Teradisk we offer CDN and WAF implementation services for your web projects, ensuring, on the one hand, that it can support large volumes of user load, scaling static and dynamic traffic, helping you to need less infrastructure to support campaigns smoothly, reducing costs and improving the user experience, and on the other hand, generating an additional layer of security that can help protect your website against a wide range of attacks.
