Protection against DDoS attacks




Protection against DDoS attacks
As a recognised web solutions provider, OVH offers you solid infrastructure with high availability for your hosting system. The only thing you have to worry about is storing your files and bringing your website to life!

Using our exclusive OVH Anti-DDoS solution, we ensure that your hosting system is always accessible, even in the event of an attack!

As Octave Klaba stresses, this protection is essential because, "It's not a question of knowing if you need anti-DDoS protection but rather when you will first be the victim of an attack."



What is DDoS?


DDoS attacks aim to render your website unavailable by overloading the server's bandwidth or monopolising its resources until the point of depletion. The cases found are generally level 7 attacks (the highest), which are based on PHP requests being carried out in great numbers, so as to saturate the system.



What is DDoS?




Today, there are more and more alerts and the risk of being faced with an attack is greater than ever, due to the democratisation of computing and the availability of the required tools. Not only the number of the recorded attacks has increased - their brute load is also greater, meaning they have the potential to damage even the most solid infrastructures.



Security, the OVH way


Guaranteeing the security and durability of our customers' online applications has always been a priority for OVH. Over the years, an experiment was forged to anticipate, manage and counteract these problems. This allowed us to develop intelligent and robust tools capable of handling massive attacks, which have been put in place on the ranges of dedicated servers and Cloud products.




These tools have been adapted and carried over to other products, such as our Web Hosting services, which did not have such well-honed protection before. Previously, we often had to suspend websites flooded with requests, in order to prevent the situation from damaging the entire service and affecting other customers.

To counter these attacks, OVH has now integrated a mitigation solution based on VAC technology. It's an exclusive combination of techniques which analyse your traffic in real time and at high speed. They detect and intercept attacks automatically, while letting legitimate requests pass through. In addition, the load balancing is even better with the introduction of PHP-FPM, enabling improved server responsiveness. As a result, there is no longer any risk of the service being saturated.
