10 Best Cloud Security Tools for 2023

More and more legacy brands are looking at digital transformation and saying ‘yes’ to cloud. Startups begin their journey with cloud. With increased adoption comes the question of safety. Cloud Security Alliance researchers reported that only 4% of organizations surveyed have sufficient security for 100% of their data in the cloud. 

What are cloud security tools? 

Cloud security tools are software applications that protect cloud-based systems, data, and infrastructure. These are designed to address the unique security challenges posed by the cloud, such as data breaches, data loss, and account hijacking. They offer a range of features such as vulnerability scanning, asset mapping, threat detection and protection, email and web application security, and backup and recovery. They can help you strengthen your cloud security posture and protect against potential threats.

6 Types of cloud security tools  

  1. Cloud Access Security (CASB): They are on-premise or cloud security tools. If SaaS application usage and access is a priority, CASB is the ideal choice.  They consolidate multiple types of security policy enforcement such as authentication, single sign-on, encryption, malware detection and protection, and device profiling among many other use cases. 
  2. Static Application Security Testing tools (SAST):  SAST tools examine the source code to find possible security flaws. They test code in real-time and prevent the loss of time and potential data security issues. Their biggest advantage is that they monitor and detect well-known vulnerabilities such as buffer overflows and SQL injection flaws. 
  3. Secure Access Service Edge (SASE):  Also known as secure service edge (SSE), this combines VPN and SD-WAN capabilities with CASB, firewalls, zero-trust network access (ZTNA), and secure web gateways (SWG). They secure access to corporate applications, SaaS, and the web regardless of location or device. 
  4. Cloud Security Posture Management (CSPM): Cloud security tools automate the identification and remediation of risks across cloud security management for IaaS, PaaS, and SaaS. It is used for risk visualization and assessment, misconfiguration management, and remediation, DevSecOps integrations, incident response, and compliance monitoring. 
  5. Cloud Workflow Protection Platforms (CWPP): They provide a low-friction cloud security solution. They are used in the DevOps process with rapid development cycles. Cloud security tools can discover workloads running in multiple cloud environments. 
  6. Continuous Security Monitoring tools (CSM): They offer visibility, real-time threat detection, and continuous configuration. They collect and analyze data for suspicious activities from multiple sources including network traffic, system event logs, and user activity. As soon as a threat is identified, it alerts your IT/DevSec team.
