Identify and Divert DDoS Attacks to Protect Your Network

With Verisign DDoS monitoring and mitigation services, you’ll have peace of mind knowing that legitimate users can access your online applications and services during a DDoS attack.


Before you can respond to suspicious cyber activity, you must identify it.

Network Traffic Baselines

We collect sample packets and other pertinent information from switches, routers and other devices to establish a view of normal traffic. We feed this information into a correlation engine for threat detection, alerts and reporting.

Real-Time Dashboard

24/7 access to a secure Web dashboard providing real-time information about your site’s network traffic patterns and enabling you to respond to potential threats quickly. Features include: alerts, bandwidth and traffic graphs, escalation plan management, reports and more.

Customized Escalation Plan

Based on the information you provide during customer set-up, Verisign creates a customized escalation plan of who to contact in the event of a network crisis.

Centralized Monitoring

We provide a view across your entire network and traffic patterns all in one place, which improves the ability to quickly and confidently initiate mitigation strategies.

Rapid, Client-Specific Analysis

We leverage our expertise and global connections to distinguish suspicious traffic from legitimate traffic, enabling organizations to receive early warning of attacks.

Stop a DDoS attack in the cloud before it can harm your network.

Seamless Integration

Our mitigation service works with multiple ISPs and third-party technologies providing a single solution to protect your applications across multiple locations.

Rapid Traffic Redirection

When a malicious event is detected, we quickly direct the harmful traffic to a Verisign mitigation site in the cloud before it reaches a customer’s network.

State-of-the-Art Filtering

Our 24/7 security team “scrubs” traffic through proprietary filtering technology and techniques that have protected critical Internet infrastructure for more than 15 years. We layer these techniques to filter out malicious traffic and allow the legitimate traffic through so that you can sustain normal business operations.

Cloud-Based Operations

By filtering malicious traffic in the cloud, Verisign stops cyber attacks before they have the chance to significantly affect your network. This eliminates the need to dramatically over-provision bandwidth to keep up with escalating attack sizes.

On- And Off-Ramping Recommendations

We provide a recommendation that fits the attack—either a "surgical" IP-based approach or a broad-scale approach. This ensures your resources are optimized and individualized for each attack.

Post-Attack Operations

Have confidence in the integrity of the data exchange process as we base secure on-ramping on your post-attack security requirements.

Hybrid Protection

We offer a joint solution that combines Juniper’s on-premise DDoS Secure with Verisign’s cloud-based DDoS Protection Service.
