A Recognized Leader in Internet Infrastructure and Cloud-Based DDoS Services

Billions of times each day, Verisign helps companies and consumers all over the world engage in communications and commerce with confidence with their cloud based security. In fact, Verisign has maintained 100 percent operational accuracy and stability of its DNS infrastructure for .com and .net for more than 17 years.

How have we done this? Through our custom built technology platform and globally connected, highly scalable network.

Our Cloud-Based DDoS Protection Is More Than Just Capacity And Hardware

Verisign’s proprietary DDoS mitigation technology, Athena, is a globally distributed DDoS mitigation system that provides comprehensive protection against network- and application-layer attacks, and specializes in mitigating Layer-7 and Secure Sockets Layer (SSL)-based attacks.

Custom built to defend critical Internet infrastructure such as .com, .net, and the A and J Root servers, Athena provides advanced mitigation capabilities and rapid protection against zero day attacks.

Our Athena technology provides:

Advanced application level protection

Advanced application level protection:

Athena supports application-level attack mitigation techniques such as decryption, inspection and filtering of SSL/HTTPS requests and immediate termination of suspicious SSL/HTTPS requests.

Advanced packet level inspection & SYN protection

Advanced packet level inspection & SYN protection:

Using a patent-pending technology, Athena mitigates TCP SYN floods transparently without blocking legitimate clients. Advanced techniques such as Cross-packet inspection and selective session state maintenance is applied to ensure attackers cannot bypass standard signatures

Expedited mitigation of zero day attacks

Expedited mitigation of zero day attacks:

Athena allows Verisign to use real-time engineering and response-based mitigation to quickly address attacks that are extremely complex or too new, and create new signatures to address previously unobserved attack vectors—often within minutes.

High availability resilient design

High availability resilient design:

Athena implements a unique load-balancing scheme with built-in monitoring of various components to ensure resiliency, and allows the platform to handle failures of components without a failure of the platform or system.

IP black and white lists support for over 1 million entries

IP black and white lists support for over 1 million entries:

Athena is designed to meet the needs of one of the world’s largest domain name infrastructures, and can handle black and white lists with millions of entries. This massive scalability ensures that trusted visitors can continue to enjoy an organization’s services without filtering or inspection.

Platform diversity for redundancy and resiliency

Platform diversity for redundancy and resiliency:

In addition to Athena, Verisign layers dedicated COTs and edge network layer filtering into its mitigation platform to ensure protection from a large range of attacks. This layered approach provides us the option to pick and choose the most effective countermeasures from the range of options.

Purpose Built and Globally Connected

For more than 17 years, Verisign has been building networks to survive the largest DDoS attacks on the Internet, using mitigation techniques that have successfully protected consumers and enterprises alike from catastrophic consequences.

Today, we see that attackers are even more skillful, and can change the attack profile in real time, making it even harder for enterprises to go it alone in building DDoS defenses – and the reason why many are turning to a cloud-based DDoS mitigation solution like ours.

Purpose built and globally connected, Verisign’s highly scalable network provides fast and effective DDoS mitigation. And allows us to work seamlessly with customers that are multi-homed with one or more ISPs or cloud providers.

What Our Network Provides:

Massive network scale

Massive network scale:

Our purpose-built, distributed global scrubbing centers are scaled to handle the largest volumetric DDoS attacks.

High availability and resilient network design

High availability and resilient network design:

Verisign DDoS Protection Services leverage multiple Tier 1 ISP transit providers interconnecting at some of the largest and best connected Internet exchange points (IXPs) in the world.

Fast traffic convergence = quicker mitigation

Fast traffic convergence = quicker mitigation:

Verisign’s network is architected to provide optimal convergence times when advertising customer IP address space; the faster the attack traffic gets to our network, the faster we can scrub the malicious attack flows and send the clean traffic back to a customer’s network.

Vast global peering

Vast global IP transit:

Verisign DDoS Protection Services’ Internet connectivity is provided by multiple Tier-1 ISP transit providers. This gives Verisign DDoS Protection Services the capacity to mitigate the largest volumetric DDoS events.
