The average enterprise now uses multiple public cloud providers. That distributed attack surface requires security teams to understand risk across every environment, not just within each cloud computing environment, to support effective data protection.
Most tools secure a single platform effectively. Far fewer provide visibility into the connections that make up a multi-cloud architecture, including public and private cloud platforms, on-premises infrastructure, firewalls, and hybrid cloud networks.
The multi-cloud security problem
Organizations adopt multiple cloud providers such as AWS, Azure, and GCP cloud solutions for resilience, cost management, access to specialized services, and reduced vendor lock-in. Security teams inherit a more difficult challenge.
Each of the major cloud providers offers native security controls, including data encryption capabilities. Those controls are effective within their own environments, but they do not provide a complete view of network reachability across cloud providers and on-premises infrastructure.
As environments grow and the attack surface expands, several common problems emerge:
- Security policies drift across cloud platforms
- Misconfigurations create unintended exposure across cloud storage and other resources
- Firewall and cloud security group changes become difficult to track
- Teams lack a consistent view of connectivity across hybrid cloud environments
- Manual reviews struggle to keep pace with change
The result is limited visibility into actual exposure, a weaker security posture, and increased difficulty maintaining consistent policy enforcement.
What to look for in multi-cloud security solutions
Many evaluations start with product categories. A better approach is to start with capabilities such as vulnerability scanning and then identify which cloud solutions address specific requirements.
Unified visibility
A solution should provide a common operational layer across cloud providers and security technologies rather than forcing teams to manage policy independently within each platform.
Security teams should be able to answer questions such as those surfaced through connectivity analysis and threat intelligence:
- Which systems can communicate with each other?
- Where does exposure exist, and how does it affect the organization’s security posture?
- Which changes created new access paths that could complicate incident response?
- Where are threat detection efforts most needed to address emerging cyber threats?
Continuous policy enforcement
Policy reviews conducted on a weekly or monthly schedule leave room for accumulating security risks.
Multi-cloud security policy management solutions should continuously evaluate changes across cloud environments against defined policy requirements, identity and access management policies, and identify violations before they weaken the organization’s security posture.
Vendor-agnostic coverage
Most enterprises pursuing multi-cloud strategies operate heterogeneous environments that include controls from multiple cloud providers alongside vendors such as Palo Alto Networks, Check Point, and Fortinet.
A solution should provide a common operational layer across those cloud service providers rather than forcing teams to manage policy independently across cloud environments and security platforms.
Network-level visibility
This is where many multi-cloud security solutions differ.
Cloud security posture management (CSPM) platforms identify cloud misconfigurations. CWPP platforms provide workload protection across cloud environments. CIEM platforms govern permissions and entitlements. CNAPP platforms combine multiple cloud security capabilities.
Each addresses a legitimate security requirement.
However, organizations also need to understand actual network reachability across cloud environments to support threat detection and risk reduction efforts. This is where Network Security Posture Management (NSPM) enters the picture.Security teams need to know whether segmentation policies are working, whether access paths are appropriate, and whether policy changes create unintended exposure.
That requires visibility into connectivity across the environment, not just posture scores or identity data. You cannot confirm that a zero-trust architecture, as described in NIST SP 800-207A, is enforced at the network level. You are making policy decisions without the data layer those decisions require.
Change automation
Firewall changes, access requests, and cloud security group updates frequently involve multiple teams and approval steps.
The strongest solutions automate policy validation, compliance checks, and workflow execution while maintaining governance controls.
Breadth of platform support
Ask vendors for specific details about supported cloud environments, virtual machines, firewalls, network devices, and security platforms.
Multi-cloud security should extend beyond individual cloud providers and support the broader network security ecosystem.
The network connectivity gap
Many security tools focus on cloud assets, workloads, identities, or configurations.
Security teams also need a way to understand how those elements connect across cloud infrastructures and the broader network.
Network connectivity intelligence provides visibility into paths between assets, applications, cloud environments, and external boundaries that can support threat detection efforts. That visibility helps teams validate segmentation policies, improve incident response capabilities, reduce risk, and identify exposure before changes are implemented.
It also supports a broader cloud network security strategy where cloud platforms and on-premises environments are governed through a consistent policy model.
Attackers do not distinguish between cloud and data center infrastructure. Security programs should not operate as separate disciplines either.
Tufin’s approach to multi-cloud security
Tufin addresses the network security policy management challenges that emerge in multi-cloud and hybrid environments.
At the foundation is the Dynamic Network Connectivity Graph, which provides visibility into connectivity across firewalls, cloud environments, routers, switches, SASE deployments, microsegmentation platforms, and hybrid networks.
That visibility supports several outcomes:
- Continuous evaluation of policy changes against defined requirements
- Consistent governance across multiple cloud environments
- Automated firewall change management and access workflows
- Faster identification of connectivity-related risk
- Improved visibility into policy drift and exposure
Tufin complements cloud security investments such as CSPM, CWPP, CIEM, and CNAPP by providing the network connectivity and policy governance capabilities those platforms do not typically address.
Implementation steps
A structured rollout helps reduce complexity.
Step 1: Current-state assessment
Inventory cloud environments, network vendors, security controls, and policy management processes.
Identify questions your current tools cannot answer about connectivity, exposure, and threat detection blind spots.
Step 2: Policy baseline
Define approved access patterns, segmentation requirements, and review processes.
Document what acceptable connectivity looks like before enforcing policy.
Step 3: Connectivity visibility
Establish visibility into connectivity across high-priority cloud environments first.
Expand coverage incrementally as teams validate results and workflows.
Step 4: Workflow automation
Automate firewall change management, access requests, and policy validation processes where appropriate.
Measure cycle times and policy compliance outcomes.
Step 5: Continuous measurement
Track policy drift, compliance status, connectivity changes, and risk trends over time.
Provide reporting that supports both technical teams and executive stakeholders.
Conclusion
When evaluating multi-cloud security solutions, focus on visibility, policy enforcement, automation, vendor coverage, and network connectivity intelligence.
The goal is not simply to identify misconfigurations across cloud providers. It is to understand how connectivity, policy, and exposure interact across your entire environment.
