Strengthening Your Enterprise Security with On-premises Firewalls
Serving as a critical first line of defense, on-premises firewalls inspect and control traffic between trusted and untrusted zones, enforcing corporate security policies at scale.
Tufin simplifies and secures on-premises firewall operations by unifying policy management across all major vendors and environments.
On-Premises Firewall Use Cases
Hybrid Policy Management
Manage and enforce policies consistently across data centers, private clouds, edge locations, and hybrid architectures—all from one platform.
Rulebase Optimization
Improve security posture and firewall performance by identifying and removing unused, overlapping, or high-risk rules, resulting in a cleaner, more efficient policy set.
Access Change Automation
Accelerate business initiatives with automated rule changes, from request to deployment, backed by full validation, approval workflows, and audit tracking to ensure safe, compliant updates.
Compliance Assurance
Maintain continuous compliance with corporate standards and regulatory frameworks such as PCI DSS and NIST by validating configurations in real-time and preventing drift before it becomes a problem.
Cross-Vendor Policy Visibility
Eliminate blind spots with a unified, end-to-end view of firewall rules, access paths, and policy posture across every vendor and environment, enabling faster investigation and better decision-making.
Even in a cloud-first world, on-premises firewalls remain essential for protecting the parts of your business that matter most. They secure data centers, branch offices, and business applications that cannot, or should not, be directly exposed to the internet.
Industry-leading solutions from vendors such as Palo Alto Networks, Fortinet, Check Point, and Cisco deliver deep packet inspection, application-aware filtering, intrusion prevention, and integrated threat intelligence. For organizations that prioritize enterprise-grade security, compliance, and granular controls, on-premises firewalls remain indispensable.
Managing Network Security Policies
Every firewall rule defines who can access what and under what conditions. Over time, these rules accumulate and become increasingly complex and stale.
Without centralized policy management, security teams face redundant or conflicting rules, policy drift, and increased unmanaged risk exposure. Effective firewall policy management ensures consistent enforcement, reduces manual effort, and enables faster, safer change implementation across the network.
Managing Policies Across Hybrid Environments
Operating in hybrid environments that span multiple firewall vendors, data centers, and cloud platforms introduces even greater network complexity.
Vendors such as Palo Alto Networks, Fortinet, Check Point, and Cisco each use distinct policy syntax, management consoles, and enforcement models. As a result, security teams must maintain visibility and control across a mix of disparate tools and configurations.
Over time, this complexity compounds:
- Duplicate or outdated rules accumulate across devices and regions.
- Legacy policies remain in place long after they are no longer needed.
- Coordinating changes between on-premises and cloud firewalls becomes slow and error-prone.
Without unified visibility, security teams struggle to answer foundational questions: What traffic is permitted? Who authorized this rule? Is it compliant with policy?

FAQs
Even as organizations adopt Amazon Web Services and other cloud platforms, on-premises firewalls remain a critical part of enterprise network security. Data centers, branch offices, and legacy applications still rely on physical and virtual firewalls to enforce security policies, control routing and connectivity, and protect sensitive endpoints inside the network perimeter.
In practice, firewall managers must account for both on-premises firewalls and cloud-based controls such as AWS Network Firewall, AWS WAF, VPC security groups, and web application firewalls protecting application load balancers and Amazon CloudFront distributions. On-premises firewalls continue to serve as a primary enforcement point for baseline security, advanced protection, and policy scope definition, especially where regulatory requirements, latency, or architectural constraints prevent workloads from moving fully to the cloud.
Managing firewall rules manually becomes increasingly difficult as environments grow and new resources are added across data centers, AWS accounts, and virtual private cloud environments. Over time, firewall rules, WAF rules, and specific rules for IP addresses, endpoints, and routing paths accumulate without consistent cleanup or validation.
Without a centralized firewall manager, teams struggle to track which security policies apply to which resources, whether prerequisites are met, or whether rules align with baseline standards. Manual processes increase the risk of misconfigurations, delayed remediation, inconsistent notifications, and gaps in DDoS protection. This is true across on-premises firewalls as well as cloud controls such as web ACLs, VPC security groups, and AWS Shield Advanced configurations.
Hybrid environments introduce complexity because firewall policies span multiple enforcement models, vendors, and management tools. On-premises firewalls coexist with AWS Firewall Manager policies, AWS WAF configurations, security group rules, and controls applied across AWS Organizations (including AWS Firewall Manager and AWS Security Hub) and multiple AWS regions.
Each platform uses different templates, policy syntax, and rule evaluation logic. As a result, security teams must reconcile firewall rules across EC2 instances, application load balancers, API Gateway endpoints, and CloudFront distributions, while also maintaining consistent enforcement on traditional firewalls. Without unified visibility, it becomes difficult to understand policy scope, identify overlapping or conflicting rules, or ensure consistent remediation across environments.
Tufin acts as a centralized firewall manager for on-premises and hybrid environments, unifying visibility, control, and automation across security policies and firewall rules. It integrates with multi-vendor on-premises firewalls while providing context for how those policies intersect with cloud resources such as Amazon VPCs, endpoints, and cloud-based security controls.
With Tufin, security teams can analyze firewall rules, validate changes before deployment, and enforce consistent policies across data centers and cloud-connected environments. Automation reduces manual effort, accelerates remediation, and ensures that firewall manager policies remain aligned with organizational standards.
Tufin supports several high-impact firewall manager use cases, including:
- Centralized visibility into on-premises firewall rules, rule usage, and policy gaps.
- Rulebase optimization to remove redundant, outdated, or risky firewall rules.
- Automated policy change workflows with validation, approvals, and audit tracking.
- Consistent enforcement of security policies across on-premises firewalls and hybrid environments.
- Faster remediation of misconfigurations that could expose endpoints or IP addresses.
- Support for audit readiness through standardized templates, baselines, and reporting.
These use cases help organizations manage firewall complexity at scale while maintaining strong network security across data centers, cloud integrations, and distributed environments.
