What are On-Premises DDoS Protection Services?

DDoS protection services safeguard websites and online resources from Distributed Denial of Service (DDoS) attacks that flood networks with malicious traffic to disrupt access. These services use advanced filtering, traffic analysis, and rate-limiting to detect and mitigate large volumes of unwanted traffic, ensuring legitimate users can still access the site. DDoS protection often includes real-time monitoring, alerts, and automated responses to handle attacks swiftly and minimize downtime. By deploying DDoS protection, businesses maintain website performance and uptime, protecting user experience and brand reputation. Overall, these services provide a critical layer of defense against cyber threats that can otherwise lead to financial and operational losses.

    F5 BIG-IP DDoS Hybrid Defender
    Get comprehensive DDoS protection for your network and at the application layer with flexibility and scale for inline, out-of-band, and hybrid deployments. Traditional DDoS solutions focus solely on a narrow range of attacks. Here are some of the reasons they’re only partially effective: By black-holing or rate-limiting, they cripple the connections of legitimate users in network layer (or flood) attacks. They’re blind to SSL traffic and dependent on their placement in the network when application layer attacks hit. On-premises defenses are rendered useless when a WAN bandwidth saturation shuts down Internet connectivity. Fortunately, F5 BIG-IP DDoS Hybrid Defender provides a greater depth of defense. It’s the only multi-layered defense that protects against blended network attacks and sophisticated application attacks, while enabling full SSL decryption, anti-bot capabilities, and advanced detection methods, all in one appliance.
