Introduction Cast AI, known for helping companies optimize cloud costs with its AI-based Kubernetes automation platform, has recently introduced automated security capabilities to enhance its existing offering. This move aims to provide organizations with both cost savings and a robust security posture for their Kubernetes clusters in the cloud.
Expanding Beyond Cost Optimization In 2023, Cast AI secured $35 million in Series B funding to expand its capabilities beyond cloud cost management. Originally designed to help reduce cloud expenditures by up to 50% for major cloud services like AWS, Azure, and Google Cloud through workload optimization and scaling, Cast AI’s Kubernetes Automation Platform is now also taking a big step into the security space.
This expansion is important considering the prevalence of Kubernetes usage; over 5.6 million developers use Kubernetes for container orchestration. While Kubernetes has proven to be integral to cloud infrastructure, ensuring cluster security is a growing concern for many organizations.
Introducing Kubernetes Security Posture Management (KSPM) In response to growing user demand for better security measures, Cast AI launched an automated Kubernetes Security Posture Management (KSPM) solution in 2024. This addition to the Kubernetes Automation Platform offers real-time scanning for vulnerabilities, misconfigurations, and compliance issues within Kubernetes clusters. Additionally, it provides remediation features, including automated patching of node operating systems.
According to Gil Laurent, co-founder and Chief Product Officer, many DevOps engineers found Kubernetes security to be challenging. “Our users told us that cloud-native security was tough to manage, so we focused on making Kubernetes clusters not only more efficient but also secure,” said Laurent.
The KSPM leverages AI for anomaly detection and remediation, using similar machine learning techniques that the company already uses to optimize resource allocation in Kubernetes environments. This builds on Cast AI’s already-established credibility in automated efficiency.
Addressing Common Threats The platform’s new KSPM tackles a broad range of security threats, divided into two major categories:
- Anomalies: Identifying unusual behaviors within clusters to provide timely alerts.
- Software Vulnerabilities: Addressing outdated components by providing automatic updates to ensure software integrity.
These improvements are aimed at enhancing the automation of security procedures that previously required manual intervention. According to Laurent, “Patching is not just about updating software—it’s about fixing vulnerabilities that could otherwise be easily exploited.”
Securing Third-Party Configurations Kubernetes’ expansive ecosystem often relies on external resources like container images from Docker Hub or deployment files from GitHub. Cast AI’s scanning capabilities validate these third-party configurations to ensure they adhere to the organization’s security standards. This is particularly crucial as Kubernetes clusters often interact with multiple third-party services that might not share the same level of security requirements.
The Role of Automation in Cybersecurity Automation plays a significant role in the new security posture management system. Laurent mentioned that while many organizations are hesitant to trust automation—due to concerns that it may break things—the AI’s role in detecting anomalies can improve cluster security without needing manual monitoring 24/7. Cast AI aims to make organizations comfortable with cybersecurity automation by providing efficient, secure solutions that reduce human error.
Human Factor and Misconfigurations Human error remains a significant cause of security vulnerabilities in cloud infrastructure, especially with misconfigurations of Kubernetes clusters. Black Hat recently highlighted misconfigurations as one of the top human-related security threats. Cast AI aims to address this by automatically identifying and correcting errors, ensuring compliance with regional regulations like GDPR in Europe and HIPAA in the United States.
Laurent believes that automated fixes are the best way forward: “You need to show not just the problem but also how to fix it. If we only show an issue without fixing it, then it isn’t security—it’s just monitoring.”
A Future of Automated Security With the addition of automated security capabilities to its platform, Cast AI is positioning itself as a leader in both cloud efficiency and security. By automating the security of Kubernetes clusters, Cast AI aims to alleviate many of the security concerns that DevOps and engineering teams currently face, ensuring more secure cloud environments while reducing operational overheads.
Laurent concluded: “Automation in security is like autonomous driving. It may be controversial, but it often provides a safer and more efficient option than relying on manual intervention. We’re taking the same approach to make Kubernetes clusters both cheaper and more secure.”
Conclusion Cast AI’s newly introduced automated security capabilities in its Kubernetes Automation Platform represent a crucial advancement in managing and securing cloud-native applications. With tools like KSPM, organizations can address both cost-efficiency and security, laying the foundation for better overall management of their Kubernetes clusters. As organizations continue to embrace cloud technologies, solutions like Cast AI’s will be key in simplifying and securing their cloud journeys.
