Common Security Challenges in Hybrid Cloud Setups
Managing hybrid cloud environments brings unique security challenges, as it involves overseeing both on-premises systems and cloud-based resources.
Limited Visibility and Monitoring
Maintaining a clear view of all activities across hybrid environments is a major hurdle. While 82% of IT professionals report good visibility in physical setups, only 20% say the same for public cloud environments. This gap arises from fragmented tools that aren't designed for distributed systems. Legacy tools often fail to keep up with the demands of modern hybrid setups, leading to tool sprawl and confusion rather than clarity.
The consequences of poor visibility are significant. Breaches take an average of 277 days to detect and contain, with prolonged incidents costing organizations an additional $1.2 million. Alarmingly, 94% of companies have experienced a data breach in the past 18 months, and over 30% of these breaches went undetected by existing security tools. This lack of oversight also results in an average of 16–20 hours of downtime per user annually, which can trigger data breaches, regulatory fines, emergency fixes, and customer dissatisfaction.
Looking ahead, Gartner predicts that more than 50% of cloud network activity will result in security incidents identified by Network Detection and Response technology by 2029. This highlights the growing need for better monitoring solutions, especially as organizations strive to meet diverse regulatory requirements.
Compliance and Regulatory Complexity
Hybrid cloud setups introduce a maze of compliance and regulatory challenges. As data moves between on-premises systems and public cloud providers, it often crosses borders, subjecting it to regulations like GDPR and HIPAA. Each cloud provider operates under its own governance framework, requiring organizations to harmonize security policies across all environments while addressing region-specific regulations.
The stakes are high. In September 2024, Cloudera reported a case where a global bank faced a multi-billion-dollar fine for failing to comply with data protection laws after a customer data breach. According to Gartner, by 2025, 85% of organizations will adopt a cloud-first approach, further underscoring the need for robust hybrid cloud security. Yet, 80% of companies experienced a cloud security breach in the past year, with 82% of these breaches involving cloud-stored data, as noted by IBM research.
The shared responsibility model in cloud computing adds another layer of complexity. Security becomes a joint effort between organizations and cloud providers, often leading to confusion and compliance gaps. Unlike static on-premises environments, hybrid clouds are dynamic and require adaptable security strategies to meet these evolving demands.
"Hybrid cloud has become essential to modern business infrastructure, with adoption expected to keep growing. While hybrid environments offer flexibility and scalability, effective governance is crucial to fully unlocking these benefits. Security, compliance, and cost management are the backbone of any successful hybrid cloud strategy."
- Parisa Moosavinezhad, Cloud Solution Architect | Expert, Devoteam
Identity and Access Management (IAM) Risks
Managing user access is another critical challenge in hybrid cloud environments. With resources spread across multiple platforms, inconsistent policies can lead to excessive or outdated access privileges, creating major security risks. Misconfigurations in cloud servers account for 19% of all breaches, with the average cost of such incidents reaching $4.41 million.
A lack of clear visibility into who has access to what further complicates matters - 52% of organizations struggle to monitor resource access and permission levels effectively. This makes it difficult to enforce proper security controls. Specific risks include account hijacking, where attackers use tactics like phishing or brute-force attacks to steal credentials. Shadow IT, where employees create unauthorized cloud resources, often bypasses IT oversight, leaving systems exposed.
Poor access management can also lead to unauthorized users or services gaining access to sensitive resources. As access needs evolve, many organizations fail to regularly review permissions, leaving critical systems at risk.
"The hybrid cloud model presents a unique prospect for mitigating data exposure cloud risks. It enables segregating sensitive or mission-critical data from the public cloud while simultaneously harnessing cloud capabilities for data that doesn't entail equivalent levels of associated cloud risks."

Practical Solutions for Hybrid Cloud Security
Securing hybrid cloud environments requires tackling challenges like limited visibility, compliance complexities, and identity and access management (IAM) risks.
Implementing Zero Trust Architecture (ZTA)
Zero Trust Architecture (ZTA) shifts the focus from traditional perimeter defenses to continuously verifying every access request. Instead of relying on static boundaries, this approach assumes breaches will happen and minimizes their impact through rapid detection and containment.
Key elements of ZTA - such as identity verification, network segmentation, least privilege access, and continuous monitoring - can address over 75% of security issues in hybrid environments. This is especially critical when you consider that 28% of unauthorized cloud access stems from compromised credentials, and phishing attacks account for one-third of cloud-related incidents.
To implement ZTA effectively:
- Use contextual identity verification based on factors like device health, location, user behavior, and access timing.
- Enforce least privilege access across all systems.
- Deploy compensating controls like privileged access management and network segmentation for legacy systems.
- Leverage SOAR platforms to ensure consistent policy enforcement and enable quick responses.
While controlling access is vital, unified monitoring plays an equally important role in maintaining robust protection.
Improving Visibility with Unified Security Tools
The distributed nature of hybrid cloud environments often creates visibility gaps, making centralized security tools indispensable for monitoring and threat detection. Platforms like SIEM (Security Information and Event Management) allow organizations to gather logs and telemetry data from multiple sources, enabling real-time analysis and incident correlation.
Here’s a quick comparison of some popular unified security tools:
| Tool | Key Strengths | Best For |
|---|---|---|
| AlgoSec | Advanced policy management, intuitive interface, automation, and visibility | Organizations needing detailed policy oversight |
| Microsoft Azure Security Center | Seamless integration with Azure and a user-friendly interface | Azure-heavy environments looking for easy integration |
| Amazon AWS Security Hub | Granular control, compliance monitoring, and native cloud security features | AWS-focused setups requiring compliance and security management |
By adopting cloud-native tools for centralized monitoring, organizations can streamline their security strategies and respond to threats faster.
Policy Enforcement with Infrastructure-as-Code
Beyond access control and visibility, embedding security directly into your infrastructure ensures both compliance and agility in deployments.
Infrastructure-as-Code (IaC) security tools analyze the scripts and code used to automate cloud setups, identifying vulnerabilities before they can be exploited. As Ariel Beck, Head of Architecture at Jit.io, puts it:
"Infrastructure as Code (IaC) security analyzes the scripts and code that automate your cloud infrastructure setup to find vulnerabilities."
IaC tools standardize deployments and automate security protocols, while Policy-as-Code (PaC) embeds compliance requirements directly into your infrastructure code. This approach improves agility, strengthens security, enhances transparency, and simplifies collaboration.
For effective implementation:
- Use version control to track changes.
- Conduct vulnerability scans and manage secrets securely.
- Enforce least privilege access.
- Integrate security checks into CI/CD pipelines.
- Perform code reviews and maintain robust logging and monitoring.
To address the growing attack surface - up by 600% in 2023 due to expanding cyber assets - take these proactive steps:
- Use cloud-native tools for centralized monitoring across hybrid environments.
- Adopt a security approach tailored to cloud workloads, ensuring real-time threat detection.
- Automate compliance checks and integrate Policy-as-Code tools like Open Policy Agent into your cloud configurations.
A strategic blend of these measures can help organizations navigate the complex hybrid cloud security landscape with confidence.
