DDoS Protection License

F5 Silverline DDoS Protection License

DDoS attacks are increasing in scope and complexity, threatening to overwhelm the internal resources of organizations around the world. These attacks combine high-volume traffic with slow, low-key, application-targeted stealth techniques. To prevent DDoS attacks from reaching the corporate network, organizations need a hybrid cloud-based mitigation solution in addition to on-premises protection.

Increase efficiency with a hybrid DDoS solution

The licensed F5 offers comprehensive DDoS protection both on-premises and with the cloud-based Silverline platform for application services.

Comprehensive DDoS Protection

Silverline’s DDoS protection service complements F5’s on-premises DDoS solution to protect organizations from the full spectrum of modern DDoS attacks. This hybrid F5 DDoS protection solution combines industry-leading on-premises DDoS protection solutions to detect and mitigate medium-sized, SSL or application-aware attacks with the high-performance Silverline DDoS protection service to stop volumetric attacks before they arrive on your network.

F5 is the first leading application services company to offer a hybrid solution for DDoS protection. By implementing Silverline DDoS Protection on top of the on-premises solution, customers can keep their businesses online when exposed to a DDoS attack, with reduced risk of downtime, real-time DDoS mitigation response times, unparalleled visibility and reporting, and cost efficiencies. The on-premises DDoS protection solution and Silverline DDoS Protection can be deployed independently or together as a hybrid solution for the most comprehensive L3-L7 DDoS protection.

Throughout the F5 infrastructure and process, Silverline DDoS Protection maintains PCI DSS compliance by protective and dominant information access, encrypting and holding data, and archiving or deleting data.

Hybrid Signaling

During a DDoS attack, F5’s on-premises solutions use Hybrid Signaling, a feature of Silverline DDoS Protection, to alert F5’s security researchers and redirect traffic for Silverline cloud remediation. Hybrid signaling enables true hybrid DDoS protection by integrating on-premises devices with Silverline’s cloud-based scrubbing technology.

Hybrid Signaling provides real-time communication with Silverline DDoS Protection when local volumetric attacks are detected, alerting the F5 Security Operations Center and enabling rapid mitigation. Hybrid signaling can also be used with the licensed F5 BIG-IP® Application Security Manager™ (ASM) on-premises, for example, to identify malicious actors. When BIG-IP ASM determines a source IP address is a bad actor, it uses hybrid signaling to block the IP address in the cloud with Silverline DDoS Protection.

Silverline DDoS Protection

Real-Time Cloud Cleanup Technologies

Any business serving content or applications over the Internet can use cloud-based DDoS protection to keep their business online during an attack with minimal impact on users. Designed to respond to the growing threats, scale and complexity of DDoS attacks, Silverline DDoS Protection provides multi-layered L3-L7 protection against all attack vectors.

Silverline Cloud Cleaning Centers are built with industry-leading security and open-source technologies to detect, identify and mitigate threats in real-time and return clean traffic to your website. With the breadth of the most advanced security hardware, software, rules engines, and custom tools, Silverline DDoS Protection provides in-depth analysis and mitigation of multi-layered attacks unachievable with other scrubbing services that use a single vendor technology architecture. Silverline DDoS Protection can run continuously to monitor all traffic and prevent attacks from reaching your network, or it can be launched on-demand when your site is under a DDoS attack.

As traffic enters the F5 debugging center, it is routed and broken down into a “suspect spectrum”. F5 then determines the best scrubbing techniques for each traffic segment and automatically routes traffic through cloud scrubbing centers for real-time mitigation. Traffic continues to be punctured as it passes through the debugging center to confirm that malicious traffic has been completely removed. The clean traffic is then returned to your website with little to no end-user impact.

Resilient Attack Mitigation

The F5’s globally distributed, fully redundant data centers and cleanup centers are equipped with advanced systems and tools designed to deal with the growing threats, scope and complexity of DDoS attacks. Silverline DDoS Protection provides multi-terabit attack protection to protect your business from even the largest DDoS attacks. The licensed F5 Silverline DDoS Protection works directly with three Tier 1 carriers to ensure bandwidth is not shared or based on peering agreements like other cloud-based services.

Ensure the Best User Experience

Invisible to your users, DDoS Attack Mitigation ensures their experience is not disrupted during a DDoS attack by always allowing legitimate customer traffic to your website and eliminating false positives. Unlike other cloud DDoS cleaning services that process traffic symmetrically and impact user experience with slow page load times or broken links, Silverline DDoS Protection has multiple asymmetric traffic return mechanisms.

This includes Layer 2 VPN (L2VPN) technology, which allows high-traffic websites to take advantage of protection without sacrificing user experience. Only a fraction of the bandwidth is required to process inbound traffic, ensuring normal traffic delivery to your users with the lowest false positive rate and maximum throughput. Depending on your needs, clean traffic can be returned to your site via GRE tunnel, proxy, L2VPN, or connect through Equinix Cloud Exchange.
