Akamai has released a line of services designed to protect web-based applications from attack.
The company said that the new services help to spot vulnerabilities in applications and protect against distributed denial-of-service (DDoS) attacks.
The Akamai DDoS Defense Architecture monitors traffic and spots potential DDoS attacks, and helps to prevent downtime.
DDoS attacks flood sites with data requests causing an outage, and have long been a favourite tool for attackers looking to disable web sites. The technique was recently used by the Anonymous group to target companies connected to the WikiLeaks crackdown.
Akamai has also updated its Web Application Firewall service, allowing administrators to scan for possible vulnerabilities and add custom rules for security protection.
Akamai said that the updates come at a time when the company is seeing increased activity from web application developers and attackers.
"The Akamai network saw more DDoS attacks against our customers' web sites in the fourth quarter of 2010 than in the first three quarters of the year combined," said chief scientist Tom Leighton.
"Companies understand the benefits of the cloud and continue to push business-critical data and operations there, but the need to protect these assets from the growing frequency and sophistication of web attacks increases dramatically as a result."
