Address Your Top 8 Network Challenges with Day-2 Automation By capturing, verifying, and enforcing network intents, up to 95% of all network service tickets, up to 50% of outages can be reduced or eliminated altogether

ADDRESS YOUR TOP 8 NETWORK CHALLENGES WITH DAY-2 AUTOMATION While there has been a great deal of focus on network automation as it pertains to initial deployment and device configuration, the biggest opportunity is found in automating Day-2 operations - which spans the entire infrastructure lifecycle. The typical large enterprise has thousands of network service tickets each month, ranging from the simple and mundane to the most complicated “headline-making” scenarios. This common device-by-device network management paradigm doesn’t usually consider the application and service delivery business requirements or their end- user experiences. Day-2 network automation enables scale for IT organizations by NetBrain Problem Diagnosis Automation System for leveraging policies and best practices created by your most experienced Managing Operations by Network Intent subject matter experts across the organization that have been incorporated into network management over the lifespan of the NetBrain’s Intent-based network management looks at the network as the infrastructure. Day-2 operations is also the perfect place to proactively delivery mechanism for various application and business service intents. enforce the network rules (or “intents”) that have been designed to NetBrain differs drastically from all other device-based network management continuously exist as part of the enterprise architecture, such as those approaches by focusing on the needs of the applications and services in use. dealing with security zones, quality of service, failover, resiliency, and By realigning network operational plans to directly support business application overall performance. service delivery, business leaders and IT professionals can focus on verifying their network’s ability to meet the needs of the business as their core KPI. What’s needed is a Day-2 vendor-agnostic intent-based automation solution for Network Operations that becomes part of the standard NetBrain PDAS (Problem Diagnosis Automation System) manages hybrid operational workflow. Not another tool, but a new strategy. One that networks as a compilation of network intents which directly supports IT service focuses on IT business service delivery intended outcomes, accelerates delivery needs. Day-2 automated network operations allows you to manage service-related tasks, and proactively verifies the infrastructure’s your hybrid network by capturing, verifying, and enforcing network design capacity to deliver IT services at levels the business requires and intents and eases problem diagnosis to ensure those conditions are maintained. prevent new applications from negatively impacting the performance NetBrain’s Automation Library offers more than 50 intents for modern enterprise of existing applications. network operations.

ADDRESS YOUR TOP 8 NETWORK CHALLENGES WITH DAY-2 AUTOMATION NetBrain PDAS Addresses Today’s 8 Most Common Network Challenges 1. Enforcement of Security Policies & Zones Network security is one of the most critical needs of a modern NetBrain's Intent-based network automation platform enterprise. In most situations, network security has been makes security enforcement a standard part of your implemented by a litany of point and overlapping solutions, each network operations. NetBrain continuously tests how well The deployment designed to manage an application or feature access requirement. information is flowing whether verifying enterprise-wide or of security But how do you know when a new security solution interferes with the granular policies and controls focusing on users, data behavior of a previously installed one? How can you confirm that types, services, or individual devices. hardware and your business network is always protected? The key is to continuously software verify the production network against the identified list of security Applications, services, and users live on different networks creates the intents including hundreds of security borders and zones enforced by and subnets, so network and security architects add illusion of “one firewall rules, access control, dynamic routing schemes, and edge segmentation to different networks with policies to allow or and done” access restrictions. deny application traffic.

Security Assurance Networks are protected from malicious traffic by security products such as firewalls, but how can these devices be tested continuously to assure they allow certain types of traffic and deny other types? Rules for transporting various traffic types and the valid source and destination addresses must be verified continuously. NetBrain uses its Intent technology to assure that all devices that are paired or load-balanced have the same sets of rules.

Critical links are no exception and great effort is put forward to assure that there is redundant connectivity between key sites and services. The problem is that redundancy and failover processes are rarely tested ‘live in production’ to assure that they will function as needed in stress conditions. Many times, Few operational catastrophic failure is the first time that the network operations teams realizes that the failover links have been mis-configured or best practices no longer functional for some other reason. It’s because few operational best practices include on-going verification of standby components. It is assumed that resiliency capabilities will function as intended. include on-going Challenges verification In the real world, a simple link failure can quickly result in a catastrophic outage – due of standby to the drift in network design that has damaged the expected failover protection. components. If the backup link isn’t properly configured, it can prevent communication altogether or perform far outside the needs of the critical link design. The backup link is your last line of defense from a blackout so it must be functional, even when not in use. Resiliency, Failover Verification NetBrain prevents this configuration drift from sabotaging your business continuity plan by: • Capturing network intent embedded inside current failover design • Monitoring the design intents continuously • Warning when detecting configuration drifts

Most enterprises surprisingly don’t have accurate While the concept of design and best-practice compliance is intuitive, the means to documentation of what’s in their networks, how they’re connected achieve it at scale is daunting. In most cases, audit and compliance processes are and how information is intended to flow. Understanding your network executed infrequently, or in direct response to audits. In worse case scenarios, this and the purpose every device serves in delivering applications is rule enforcement is addressed immediately “after” a catastrophic incident occurs. fundamental to maintaining operational compliance. In addition, adhering to security policies and regulatory compliances (e.g., HIPAA, Achieving Design Compliance and Best Practice Audit PCI-DSS, NIST) can take up a significant amount of time. What’s more, the inability to proactively monitor and enforce security rules, NetBrain enforces design compliance and security policy adherence by: puts you at greater risk of threats and security breaches which in • Explicitly encoding best practice rules with Intent some cases go undetected for days or weeks.

Hence, network operations teams end up spending unnecessary time solving the same problems over and over which is very ineffective and reduces scalability.

ADDRESS YOUR TOP 8 NETWORK CHALLENGES WITH DAY-2 AUTOMATION Summary NetBrain empowers network operations teams manage their networks by their design intents that directly support their business applications. It’s no longer necessary to focus on the mix of hardware vendors, only what purpose they serve in the greater network. In this way, we help NetOps better align with business needs. Networks should be redefined as the tens of thousands of network intents that they deliver, rather than the static set of the thousand devices which comprise it on a network diagram. The number of intents those devices support may be 10 or 100-fold the number of devices. And by capturing, verifying and enforcing network intents, IT and the business can be perfectly aligned. About NetBrain Technologies Founded in 2004, NetBrain is the market leader for NetOps automation, providing network operators and engineers with dynamic visibility across their hybrid networks and low-code/no-code automation for key tasks across IT workflows.
