Cloud Security Services

Powerful security for your digital content

Maintain content availability and thwart attacks

You can’t afford to have your website to go down because of a DDoS attack, and you can’t afford your digital content to be stolen or accessed by unauthorized users by a web application cyber-attack. In both cases you are losing revenue. But is an on-premise security solution the answer? Not when your digital distribution is global.


You can have the best box money can buy installed in front of your web server, but if your uplink gets flooded with bot traffic, it won’t matter—no legitimate requests will be able to reach your origin or your content. To deal with today’s volumetric and targeted attacks, you need comprehensive security services that scale with the growth of your business, that keep your site available, and your content protected.

DDoS Attack Interceptor

Learn about DDoS detection and mitigation technology.

Limelight Cloud Security Services offer a layered defense against malicious website attacks and unauthorized content access, providing a number of valuable features including:

Defensive Protection

The large size and distributed nature of the Limelight Content Delivery Network (CDN) inherently protects your infrastructure against malicious traffic flooding by absorbing most attacks before they ever reach your origin.

Vigilant Application and Data Security

Limelight Cloud Security Services use the Orchestrate Platform’s global reach to secure content and mitigate attacks on your website and web servers. They include encrypted content delivery and multiple access control methods that enable you to protect your digital assets.

Security Alert

Alert provides globally distributed anycast addresses to ensure attacks are distributed across multiple POPs, as well as DDoS attack detection and alert notifications.

WAF Express

Web Application Firewall (WAF) Express includes Security Alert features and additional security capabilities by enabling per IP address rate limiting from a single IP address, and basic OWASP Top 10 WAF filtering rules. WAF is integrated with Limelight’s global CDN, providing a secure, distributed architecture that delivers cost-effective protection for web applications without sacrificing performance for security, by detecting and blocking attacks at the network edge in real-time from cyber threats.

WAF Complete

WAF Complete includes Security Alert and WAF Express features and adds active mitigation of Layer 7 DDoS attacks including good bot/bad bot detection, and enhanced WAF protection with custom rules per web application. WAF protection is complemented with 24X7 security operations center monitoring and access to dashboards displaying rules state and request handling.

DDoS Attack Protection and Mitigation

Strong origin and website protection against a wide range of DDoS attacks with real-time behavior analysis identifies attacks within legitimate traffic. Globally distributed detection includes zero-day attacks with offending traffic scrubbing at the edge, and you’ll only be billed for delivered clean traffic.
