What is cloud security?

Cloud security is the technology, policies, services and security controls to protect data, applications and environments in the cloud.

Cloud security focuses on:

  • Ensuring the privacy of data across networks
  • Handling the unique cybersecurity concerns of businesses using multiple cloud services providers
  • Controlling the access of users, devices and software

Why is cloud security important?

For businesses shifting to a cloud-based model, security is a top concern. Organizations must design and implement a comprehensive security solution to protect from an expanding array of threats and increasingly sophisticated attacks within the cloud environment. Traditional security strategies intended to protect on-premises, hosted networks and associated assets are unsuitable for the cloud and must be updated to address these threats within the cloud environment.

Enterprises must adapt their security approach to protect this new environment. This includes rethinking and redesigning the security strategy to include real-time, advanced monitoring, detection and response capabilities specifically for the cloud. Protective measures such as microsegmentation and encryption should also be used to minimize damage and contain the threat should a breach occur.

Cloud security considerations

Cloud security should start with a security platform that is purpose-built in the cloud, for the cloud. When selecting a cybersecurity vendor it is important to understand the company’s strengths and differentiators, as well as other overarching factors, such as cost, support, integration, scalability and flexibility. Here we present 10 of the most reputable cybersecurity providers on the market, including their key features, services and stand-out attributes.

In this post, we explore 10 leading cloud security companies, their differentiators and key solutions.
