How To Provide Security For Cloud Servers

By Cloud Techie Friday, 8 February 2013
Security is the main concern for all the companies who operate on cloud. Most of the companies face security challenges in a dynamic and scalable cloud environment. If we take public clouds such as Amazon AWS, they provide limited security features for the servers and storage. In that case, if you want to incorporate more security features on to your cloud servers, you have to go for the  third party cloud security providers. Here is where CloudPassage comes in to play. CloudPassage is a startup which provides security for the servers which operate on cloud. In a elastic and scalable environment cloudpassage deploys a better security for the servers. CloudPassage is the first SaaS provider for cloud server security.
