What is CDR (Cloud Detection and Response)?
The cybersecurity landscape is evolving rapidly. Part of this evolution is driven by businesses increasingly shifting their operations and data to the cloud. What are the implications for organizations that need to protect their digital assets? Many enterprises are strategically pivoting their security approach to integrate cloud detection and response (CDR) — in conjunction with expert incident response and breach recovery services — to address the unique challenges posed by cloud environments.
As businesses leverage cloud services for their flexibility and scalability, the complexity of securing these environments grows. CDR can meet the challenges of this complexity. In this post, we’ll look at what CDR is, why it’s essential, and how it fits within the broader context of cybersecurity technologies.
Before we dive into CDR, let’s briefly review the top behaviors of adversaries lurking in the cloud today.

Adversaries use a range of tactics, techniques and procedures to target cloud environments. Below are some of the common TTPs used to target the cloud.
- Initial access: Threat actors often use credentials from legitimate accounts, reset passwords, or exploit public-facing applications to gain initial cloud access. From there, they seek further access via credentials in files or through instance metadata services from cloud providers.
- Discovery: Attackers examine cloud accounts, seeking long-term latent access, privilege escalation, and reachable network services. They also search for permission groups, infrastructure, and storage buckets.
- Privilege escalation: By accessing accounts with higher privileges, attackers can gain more access to cloud resources.
- Lateral movement: Leveraging SSH, Remote Desktop Protocol (RDP), or Server Message Block (SMB) protocols, attackers move laterally within a cloud environment. They may also look to cloud orchestration tools to aid them.
- Defense evasion: Efforts to bypass security include disabling security products in VMs or trying to impersonate valid users by connecting via proxies geographically closer to their locations.
These behaviors underscore the need for robust defense mechanisms tailored for the cloud. This leads us to CDR and its critical role in the modern cybersecurity strategy.
CDR components and use cases
CDR is a security approach specifically designed for cloud environments that focuses on threat detection, immediate incident response, and service integrations. It aims to ensure comprehensive security coverage that is tailored to the unique aspects of cloud computing, such as scalability, data sovereignty, and innovation.
Key components of CDR include:
- Complete unified CNAPP: combines technologies such as CWP, CSPM, CIEM and ASPM into a single solution
- Proactive services: including threat hunting, incident response, proactive security services
- Adversary intelligence: up-to-date intelligence on the latest behaviors / TTPs of adversaries.
Traditional point security solutions aren’t equipped to fully handle the dynamic nature of the cloud, with its rapid scalability, ephemeral resources, and global distribution of services and data. CDR offers a more adaptable and integrated approach. It's crafted to handle the cloud's fluidity, leveraging real-time data and cloud-native threat hunting capabilities to protect your digital assets.
CDR solutions' capabilities make them a vital tool for securing cloud environments, offering a specialized approach that traditional point solutions can't match. However, implementing CDR comes with its own set of challenges:
- Integration complexities when working with existing security tools and cloud services
- Alert management and prioritization to avoid alert fatigue and ensure that critical threats are addressed promptly
Because of these challenges, CDR is most effective when it is part of a larger, unified cybersecurity platform that integrates capabilities for prevention, detection, and rapid response. Couple this with adversary-based threat intelligence and 24/7 services from a team of cybersecurity experts, and the result is a CDR approach that ensures the protection of your cloud environments.
The benefits of Cloud Detection and Response
CDR can be transformative for an organization’s cloud security, vastly enhancing its ability to deal with cloud-based threats.
- Reduce cloud risks by proactively identifying and mitigating vulnerabilities
- Stop cloud breaches by preventing unauthorized access and subsequent data exfiltration
- Enhance visibility into cloud environments
- Respond faster with quicker threat detection and mitigation
- Minimize the blast radius of an incident due to swift detection and response
- Employ scalable security measures that adapt to the changing scale of cloud resources for consistent protection
