Hybrid clouds are the default now: 70% of organizations run at least one public cloud alongside a private cloud or on-premises data center, and that mix keeps growing. More cloud providers, cloud environments and cloud services. More connection points. Each one widens your attack surface faster than manual security processes can track. Here’s what hybrid cloud security challenges actually look like day to day, and how Tufin’s control plane helps you manage each one.
Fragmented visibility
You cannot secure what you cannot see. Hybrid cloud environments span on-premises firewalls, cloud security groups, SASE edges and microsegmented workloads across your IT infrastructure. Each security solution has its own console and its own view of connectivity across your cloud infrastructure. Your network and security teams switch between tools, manually correlate data and still miss the full picture.
The gaps compound. A firewall rule permits traffic you thought was blocked. A cloud security group left open during a migration never gets closed. A new workload spins up and no one knows what it can reach. In a hybrid cloud environment, fragmented visibility is the default state, not the exception. It is the root condition from which most other challenges grow.
Inconsistent policy across environments
On-premises firewalls enforce policy one way. Cloud-native security controls use a different model. SASE platforms add another layer. Each vendor’s shared responsibility model draws a different line between what they secure and what you do, and none of those lines are the same shape. When you need a single intent (“this application tier must never reach the internet directly”), translating that intent into consistent rules across all three is a manual, error-prone process.
Inconsistency creates exploitable gaps. A policy that holds across your on-premises infrastructure does not automatically carry through to your public cloud environments, such as an AWS VPC or Azure virtual network. Engineers writing cloud-native rules often do not know what the corresponding firewall security policies say. The longer your hybrid footprint runs without a unified policy model, the more drifts from established security best practices and what you intended to enforce. This is a central reason why hybrid cloud security remains difficult even for mature organizations.
Configuration drift
Hybrid environments change constantly. Rules get added for a project and never removed. An emergency change bypasses the normal review process. A cloud security group is widened for a test and never tightened again. Over weeks and months, your security posture drifts away from your approved baseline.
Drift is dangerous because it is invisible without continuous monitoring, allowing security concerns to accumulate unnoticed. Each individual change looks minor. Together they create a permissive posture that neither reflects your policy intent nor matches your risk tolerance. Manual audits catch some of it. By the time an audit runs, the drift has already existed for weeks. That drift puts regulatory compliance and governance at risk too: a control that satisfied last quarter’s PCI DSS review may already be out of scope by the time you need it again. Poor cloud security architecture decisions compound the problem: once baked in, they are expensive to unwind.
Lateral movement risk
Once a compromised workload is inside your network, lateral movement is the mechanism by which limited access becomes a serious data breach. Most data breaches escalate through lateral movement after initial access, not at the point of compromise. In a hybrid cloud environment, the paths for lateral movement multiply. Flat network segments, overly permissive east-west rules and missing network segmentation boundaries all provide routes from a compromised endpoint to your most sensitive systems.
NIST SP 800-207A addresses this directly in its Zero Trust architecture guidance for multi-cloud environments: explicit verification of every connection, least-privilege identity and access management, multi-factor authentication and the assumption that perimeter controls alone are not sufficient. Skipping that verification doesn’t just raise the risk of compromise: it slows incident response, because responders have to reconstruct network paths that should already be documented. Enforcing these principles across firewalls, cloud security groups and microsegmentation policies simultaneously is not achievable through manual processes at machine speed.
Manual change bottlenecks
Network change requests move through ticket queues, manual reviews and firewall-by-firewall implementation. In a hybrid environment with dozens of vendors and hundreds of rule sets, that process is both an operational bottleneck and a security risk. Changes that should take minutes take days. Security teams approve changes on trust rather than against verified policy.
AI-accelerated development cycles and faster application deployment across cloud services drive more change, faster. A manual process built for a simpler network does not scale to what hybrid environments now demand.
Tufin’s approach to hybrid cloud security challenges
Tufin is the first and only solution for Multi-Vendor Agentic Network Security. Each challenge above has a specific mechanism in Tufin’s platform.
Fragmented visibility: the Dynamic Network Connectivity Graph. Tufin’s foundation is the industry’s only Dynamic Network Connectivity Graph. It models your entire network (firewalls, cloud, routers and switches, SASE, microsegmentation and hybrid) as a single connected graph. You see who can talk to whom, what is reachable, where exposure exists and whether segmentation holds. Not a static snapshot: it’s live network visibility that updates as your network changes.
Inconsistent policy: the control plane. Tufin’s control plane sits on top of the graph as one operational layer. You define policy intent once. The control plane translates and enforces that intent across every vendor in your environment, from on-prem infrastructure to the cloud. The gap between what you intend and what is enforced closes.
Configuration drift: continuous posture monitoring. Tufin monitors your actual configuration against your approved baseline continuously, not periodically. Drift is detected the moment it occurs. Violations surface in real time. You do not wait for the next audit cycle to find out that months of incremental changes have moved you off policy.
Lateral movement risk: network segmentation visibility. The Dynamic Network Connectivity Graph shows every path through your network. Tufin identifies where east-west rules are too permissive, where segmentation boundaries are missing and where a compromised cloud workload could move. This is where Zero Trust principles become daily enforcement. You see the exposure before it becomes a breach, which shortens incident response because responders start from live graph data instead of reconstructing connectivity from scratch.
Manual change bottlenecks: proven network playbooks and agentic AI. Tufin’s vendor-agnostic agentic AI operates across the whole network. Change requests go through automated policy verification, risk analysis and automated implementation where policy permits. Role-based access control keeps approvals in the workflow, so machine speed does not mean unchecked speed. Playbooks encode your proven processes so machine-speed change does not bypass your controls. What took days takes minutes. What required expert review gets policy-checked automatically.
The graph is the data layer. The control plane is the operational layer. Tufin’s breadth and depth of multi-vendor coverage, including the Open Policy Model for additional technologies, means every vendor in your hybrid environment is governed through one system.
A healthcare provider case study shows this model working end to end, from fragmented visibility to automated change.
Conclusion
Hybrid clouds aren’t getting simpler. The environments keep growing, the change velocity keeps increasing and the manual processes most teams rely on keep falling further behind. Fragmented visibility, inconsistent policy, configuration drift, lateral movement risk and change bottlenecks are solvable, but only with a platform built to operate across the whole network at machine speed. Tufin’s Dynamic Network Connectivity Graph and control plane give you exactly that.

Frequently asked questions
What are the main hybrid cloud security challenges?
The main hybrid cloud security challenges are fragmented visibility across on-premises and cloud environments, inconsistent policy enforcement across different vendor controls, configuration drift from continuous network change, lateral movement risk from insufficient segmentation and manual change processes that cannot keep pace with modern hybrid environments. Each challenge compounds the others: poor visibility leads to drift, drift creates lateral movement paths and manual processes cannot catch any of it fast enough. Left unresolved, that chain leaves organizations vulnerable to security threats, often ending in a data breach or a failed audit.

Why is hybrid cloud security so challenging?
Hybrid cloud security is so challenging because hybrid cloud environments are not one thing. They’re multiple vendors, multiple control planes and multiple policy models operating in parallel with no native way to see or govern the whole. Each cloud provider and firewall vendor has its own security model, which means you have to translate your security intent into different rule formats across different tools manually. That translation process introduces inconsistency at scale. The pace of change in hybrid environments means the inconsistency accumulates faster than manual processes can correct it.

How do you overcome hybrid cloud security challenges?
You overcome hybrid cloud security challenges by replacing fragmented, manual processes with a unified control plane that strengthens your hybrid cloud security architecture. That means a single model of connectivity, not separate tools for each environment, combined with continuous policy enforcement and automated change management. The goal is to eliminate the gap between your intended security posture and your actual enforced posture. Close that gap at machine speed rather than audit-cycle speed.
