“Knowing that there’s always someone that I can talk to at Limelight who can solve any problem is very reassuring. Limelight gives us peace of mind. It has a very fast deployment, but technology is only half the picture. The customer service I get from Limelight is second to none.”

Challenges Securing and Protecting Your Content

Ensuring a great quality of experience for users entails securing and protecting content from a variety of potential threats. DDoS and web application attacks are the biggest cyber threat facing organizations today. Not only are the frequency and sophistication of attacks increasing, but so too is duration and purpose. We’ve even seen evidence of permanent attacks for the purposes of data theft or ransom. Delivering video brings its own challenges as well—securing content against theft during network transmission or unauthorized access, and ensuring compliance with licensing restrictions. With the cost and complexity of preventing and responding to security breaches on the rise, only a comprehensive suite of global cloud-based security services, rather than on-premise equipment, allows you to keep abreast of the latest threats and preventive mitigation measures without adding latency to the delivery experience.

How Limelight Cloud Security Services Solve These Challenges

Limelight Cloud Security Services provide powerful features to protect against attacks on websites and unauthorized access or theft of content. DDoS Attack Interceptor keeps your websites available with globally distributed detection, sending suspicious traffic to a scrubbing center, delivering only clean traffic, avoiding bill shock, and assuring no performance penalty. WAF application security extends attack protection to HTTP conversations by identifying and blocking malicious requests and responses. Security of content in transit against theft is provided by the largest SSL footprint, and website access authorization is controlled by geo-fencing, URL tokenization, and IP address white and black listing so you can enforce licensing restrictions.
