Cloud security has risen to top of mind following a spate of data breaches and ransomware attacks over the last few months. With so many organizations housing data and applications in the cloud, more and more people are taking a deeper look at what exactly cloud security involves. 

What is Cloud Security? 

Cloud security can be something of a nebulous area. It can apply to: 

  • Data in the cloud
  • Applications running in the cloud
  • Cloud services being used by the enterprise
  • Securing data that is being sent to or from the cloud 
  • Encryption of cloud data 
  • Access rights for cloud data and functions 
  • Authentication for the cloud 
  • Secure storage of data in the cloud 
  • Segmentation of data hosted in the cloud  

Even though that is only a partial list, it makes it obvious that cloud security is not that much different from enterprise security. There are a great many avenues of access to secure as well as platforms and data repositories to safeguard. 

Cloud security, then, encompasses a wide swath of the IT landscape. It includes prevention of unsanctioned access as well as detection of potentially malevolent activity. It deals with securing the perimeter, often now regarded as little more than a speed bump for attackers, as well as user education to thwart phishing and ransomware, and even backup, recovery, and disaster recovery.

Top Cloud Security Vendors 

As there are so many aspects to cloud security, it is challenging to narrow down the many vendors that cater to this security category. Therefore, this list has more entries than most other top vendor lists in an effort to cover as much ground as possible. 


The Guardicore Centra security platform delivers microsegmentation controls to reduce the attack surface and detect and control breaches within east-west traffic. It protects cloud-native applications, including serverless computing and Platform as a Service (PaaS), It also offers access control, application ringfencing, and ransomware prevention and containment. 


Pentera’s automated security validation platform provides visibility into vulnerabilities that adversaries and ransomware exploit to compromise assets in cloud and hybrid environments. Security teams are provided a comprehensive attack operation view to assess resilience against attacks and security control efficacy. It automates real-time penetration tests at cloud scale, performing the actions a malicious adversary would — reconnaissance, sniffing, spoofing, cracking, (harmless) malware injection, file-less exploitation, post-exploitation, lateral movement and privilege escalation — all the way to data exfiltration. 


Veritas NetBackUp Recovery Vault secures data in the cloud, keeps it safe from ransomware, and prepares for disaster recovery while being able to meet compliance and governance requirements. It is cloud-based storage-as-a-service that provides a fully managed secondary storage option for NetBackup users. A UI simplifies provisioning, management, and monitoring of cloud storage resources and retention policies. Recovery Vault offers a single repository for on-premises and public cloud workloads. 


Cloudian’s HyperStore object storage provides data immutability via S3 Object Lock technology. Once data is written, it can’t be changed or deleted for a user-specified time period. That data is protected from hacker encryption, and organizations can recover their data in the event of an attack. Unlike air-gap solutions that require manual intervention and may entail long recovery times, Object Lock can be part of an automated backup process.
