How does Arbor TMS Mitigation protect against DDoS attacks?
Arbor TMS Mitigation effectively protects your network from Distributed Denial of Service (DDoS) attacks, one of the most common and dangerous forms of cyberattacks. In a DDoS attack, a server or network is overloaded by a massive number of requests originating from compromised devices, often part of a botnet. The aim is to exhaust the target's resources, such as bandwidth or server performance, and exclude legitimate users from access. Arbor TMS analyzes traffic in real time, detects malicious patterns and filters out malicious traffic before it reaches your systems. The solution accurately distinguishes between legitimate requests and attacks, so your network can continue to operate uninterrupted. This proactive defense protects not only against volumetric attacks, but also against protocol and application layer attacks. With scalable protection against data streams from a few Gbit/s to over 1 Tbit/s, Arbor TMS ensures uninterrupted uptime and reliably secures your systems against cyber threats. At the same time, the technology provides detailed reports on attacks to better manage future risks. Arbor TMS is therefore an indispensable component for companies that rely on maximum security and availability.
