Security of Master Internet customers is our first priority

Security belongs to one of our long-term priorities, at Master Internet. With the increasing number of security threats, network attacks and anomalies lately, we have started to set up our own CSIRT security team. Its goal is to increase security in the Master Internet Autonomous System (AS24971) and to improve the quality of services in the field of this commercial network. We emphasize the sharing and exchange of information with other CSIRT teams and therefore we believe it will help faster and more efficient solutions to the problems associated with the attacks. Because it is just information about the characteristics of the attack, the source network, or the successful method of defense, along with the speed of receiving them, which are key factors in resolving such incidents.
