Network Visibility: Security Applications of Network TAPs, Brokers and Bypass Switches

Security starts with awareness, but what happens when critical traffic slips through unnoticed? For security teams and network administrators alike, network visibility isn’t just a luxury—it’s a necessity. As threats become more sophisticated, ensuring complete, real-time access to network traffic is the first step in defending against malicious activity. This is where technologies like Network TAPs, Network Packet Brokers, and Bypass Switches come into play.

What is Network Visibility?

Network visibility refers to the ability to monitor all traffic flowing across a network—north-south (between users and data centers) and east-west (between internal systems, users and endpoints). Without it, blind spots emerge, leaving room for attackers to move undetected.

Visibility tools like Network TAPs (Test Access Points), Network Packet Brokers (NPBs), and Bypass Switches are the foundation for building a resilient, secure, and high-performance network. Each plays a unique role in feeding security appliances the data they need to function effectively.

Network TAPs: Your First Line of Insight

Network TAPs (Test Access Points) are dedicated hardware devices designed to deliver a real-time, unfiltered copy of network traffic. Placed in-line between network segments, TAPs allow all data to flow through uninterrupted while simultaneously duplicating that traffic for monitoring and security tools. Unlike other methods that may filter or miss packets under load, TAPs provide a complete and accurate view of every packet traversing the network—ensuring your tools receive 100% of the data, with zero interference, loss, or blind spots.

Security Use Cases:

Intrusion Detection Systems (IDS) rely on clean, complete traffic to detect anomalies.

Forensics and packet capture solutions use TAPs to store traffic for analysis after an incident.

Decryption appliances can tap into SSL/TLS sessions for deep inspection.

Network TAPs are available from vendors like Garland Technology, Cubro, Profitap and Keysight.

Network Packet Brokers: Smart Traffic Management

Gaining visibility is just the first step—managing that traffic effectively is where the real challenge begins. This is where Network Packet Brokers (NPBs) come into play. These smart, purpose-built devices aggregate traffic from multiple sources, then filter, de-duplicate, and reformat it before sending it to your security and monitoring tools. 

By delivering only the relevant data in the optimal format, NPBs reduce tool overload, eliminate unnecessary noise, and ensure that each system receives precisely what it needs to operate at peak efficiency.

Security Use Cases:

Traffic filtering: Send only relevant data to specific security appliances to reduce overload. 

Load balancing: Distribute traffic across multiple tools for redundancy and scalability. 

Packet deduplication and header stripping: Eliminate noise and unnecessary metadata that can bog down inspection.

Bypass Switches: High Availability for In-line Security

Bypass Switches, unlike TAPs and Network Packet Brokers, are purpose-built for in-line security tools—such as firewalls, intrusion prevention systems (IPS), and secure web gateways—that actively inspect and control live traffic. Because these tools sit directly in the path of network data, any failure or maintenance downtime can disrupt the flow of traffic and impact availability. Bypass switches solve this challenge by intelligently redirecting traffic around the in-line device if it becomes unresponsive or needs to be taken offline. This ensures continuous uptime, minimizes risk, and allows security teams to maintain and upgrade in-line defenses without interrupting business operations.

Security Use Cases:

Fail-safe failover: If an in-line appliance fails or is taken down for maintenance, bypass switches keep traffic flowing uninterrupted.

Heartbeat monitoring: Ensure that in-line tools are healthy and responsive.

Scheduled updates and maintenance windows: Perform patching or upgrades without interrupting traffic.

The Power of an Integrated Visibility Fabric

Individually, TAPs, Brokers, and Bypass Switches solve specific problems. Together, they form a visibility fabric—a unified, scalable approach to traffic monitoring that supports both performance and security initiatives.

If you’re struggling with visibility gaps or underperforming security tools, it’s time to rethink your monitoring strategy.

Troubleshooting Cheat Sheet: Layers 1-3

Any time you encounter a user complaint, whether regarding slow Internet access, application errors, or other issues that impact productivity, it is important to begin with a thorough understanding of the user’s experience.

Not sure where to begin?  User complaints usually fall into three categories: slow network, inability to access network resources, and application-specific issues.

Based upon the complaint being presented you need to understand the symptoms and then isolate the issue to the correct layer of the Open Systems Interconnection (OSI) model.

The following Troubleshooting Cheat Sheet shows the questions to ask with a typical slow network complaint.

What to Ask What it Means
What type of application is being used? Is it web-based? Is it commercial, or a homegrown application? Determines whether the person is accessing local or external resources.
How long does it take the user to copy a file from the desktop to the mapped network drive and back? Verifies they can send data across the network to a server, and allows you to evaluate the speed and response of the DNS server.
How long does it take to ping the server of interest? Validates they can ping the server and obtain the response time.
If the time is slow for a local server, how many hops are needed to reach the server? Confirms the number of hops taking place. Look at switch and server port connections, speed to the client, and any errors.

Quick OSI Layer Review

With these questions answered, working through the OSI model is a straightforward process. When dealing with the different layers, understanding how each layer delivers data and functions will impact how you would troubleshoot each layer.

Physical Layer

  • If it can blind or shock you, think Physical Layer
  • Defines physical characteristics of cables and connectors
  • Provides the interface between network and network devices
  • Describes the electrical, light, or radio data stream signaling

Data Link Layer

  • Converts signals into bits which become the packet data that everyone wants
  • Performs error detection and correction of the data streams
  • Manages flow and link control between the physical signaling and network
  • Constructs and synchronizes data frame packets

Network Layer

  • Controls logical addressing, routing, and packet generation
  • Carries out congestion control and error handling
  • Performs route monitoring and message forwarding

Assessing the Physical Layer

Generally speaking, Physical Layer symptoms can be classified into two groups of outage and performance issues. In most cases, investigating outage issues is the easiest place to begin, as it’s a matter of confirming the link light is out or that a box is not functioning. Additionally, validating equipment failure is a matter of replacing the cable or switch and confirming everything works.

Physical Layer issues are overlooked by people pinging or looking at NetFlow for the problem, when in reality it’s a Layer 1 issue caused by a cable, jack, or connector.

The next step in investigating Physical Layer issues is delving into performance problems. It’s not just dealing with more complex issues, but also having the correct tools to diagnose degraded performance. Essential tools in your tool box for testing physical issues are a cable tester for cabling problems, and a network analyzer or SNMP poller for other problems.

Assessing Physical Performance Errors

In diagnosing performance issues from a network analyzer, you’ll notice that there are patterns common with these errors, which are usually indicative of what’s causing the Physical Layer problem. These can be divided into intelligent and non-intelligent errors.

Intelligent Errors: An intelligent host is smashing into your network signal and corrupting the data.

Example: Overloaded WiFi network or a busy channel.

Non-Intelligent Errors: An outside entity causing noise that interferes with the signal or flow of data across the network.

Example: A microwave interfering with a WiFi signal.

Climbing Further up the Stack

Confirming performance problems, taking a systematic approach to troubleshooting, and understanding how communication occurs across the layers of the OSI model are key to slashing troubleshooting times and improving resolution accuracy.

Year-End Network Monitoring Assessment

Planning for the Future

As we approach the New Year, many organizations’ data centers and network configurations are in lockdown mode. Whether this is due to assuming a defensive posture against the onslaught of holiday ecommerce traffic, or an accommodation to vacationing staff, the situation provides network managers an opportunity to perform a year-end network monitoring assessment

Establish Future Goals, Identify Current Weaknesses and Make Sure Core Tasks and Goals Are Achieved

Q. How many locations will you need to monitor in the New Year?

If there are new server clusters or even new data centers in the works, be sure to plan accordingly, and ensure that your network monitoring tools will have visibility into those areas.  Network Taps can be used to incorporate more points of visibility for your existing monitoring tools within your growing network. Advanced appliances such as Network Packet Brokers (NPBs) can perform more sophisticated switching and filtering to optimize visibility within that network sprawl.

Q. What traffic will you be responsible for monitoring?

If you are providing network support, you need to understand immediately the nature, volume and security of the traffic flowing over your network. Is your organization planning to implement new applications or services on the network? Even the introduction or expansion of virtualization will require a monitoring plan that incorporates Virtual Taps. Additionally using advanced features on a packet broker like load balancing can extend the useful life of existing tools by sharing current traffic across a pool of devices.

Q. What new threats will the network face, and what preventative measures will you add?

The growing phenomena of advanced persistent threats (APTs) and directed attacks against network vulnerabilities demand a stronger response from security personnel. Up to 75 percent of devices within an organization’s network can contain a known security vulnerability. Many organizations deploy a defense-in-depth strategy with overlapping security tools to provide more robust security coverage. Be sure to schedule software updates for all of your network security tools, and make sure those security tools have total visibility of the traffic they are monitoring.

Q. What is your replacement plan for older equipment?

Take inventory of network equipment that have reached end-of-life, end-of-sale or end-of-support.. Budgeting for, and planning ahead for the obsolescence or re-tasking of these devices should be included in your plan for the coming year.

Q. What are your redundancy and failover plans?

One option for extending the useful life of your legacy monitoring tools is to utilize them as redundant tools in case of failover. Utilizing a bypass switch or high-availability modes in NPBs can make use of these tools in the event a primary device is put in maintenance mode, taken offline, or experiences a hardware failure. Consider assessing your older equipment on the basis of discarding the equipment entirely OR re-purposing it as a hot-standby.

Q. Have you included hardware/software maintenance in your annual budget?

Most hardware vendors offer annual maintenance and service plans for their devices. Renewing and maintaining these plans is critical to ensuring that you have access to the latest software updates. Additionally, should any of your devices experience hardware failure, advance replacement plans can get replacement equipment into your network as soon as possible.

Managing Your Application Performance

apmcomponents1 end user monitoring

Are you are planning to implement new IT projects such as data center consolidation, server virtualization, cloud computing, or perhaps adding new applications on the network?  Do you understand exactly how these upgrades will affect the existing applications and the user experience?  What strategy are you going to use to ensure application performance is not compromised?  It is imperative that you understand how each of the components can affect overall application performance.

A Strategy you can use to Manage Application Performance (APM)

Most companies have some sort of visibility of their network systems via the network elements, but a healthy infrastructure does not necessarily mean that your applications are running efficiently because they do nothing to monitor the actual transaction.  There are many different components to APM, so what capabilities do you need to accurately monitor, measure, and troubleshoot?

6 Components of Application Monitoring

Monitoring the End-user Experience is quite different from Infrastructure Monitoring. We actually measure the end-user experience so we see what they see.

apmcomponents1 end user monitoring 
  • Measures response time and availability from the end user’s perspective
  • Aligns performance management with the needs of business users

 

Application Mapping is a separate dimension to APM this takes the different bits about applications and maps them together so you can trace an application and its dependencies/relationships across the network.

apmcomponents2 Application Mapping 
  • Discover application components and their relationships
  • Fundamental for managing an application

 

Transaction Following/Tracing is a critical component is being able to trace transactions on the network through multiple servers that all communicate to make up an application.

apmcomponents3 Transaction Following Tracing 
  •  Follow transactions through application tiers and components
  • Trace performance of each transaction at the code level
  • Holistic view of transactions from end-to-end

 

Deep Application Component Monitoring –  deep inside the system that runs the code allows you to get to the fine detail, and why there may be application issues.

apmcomponents4 Deep Application Component Monitoring 
  • Collect fine-grained metrics from application internals, including code-level performance
  • Produce detail needed for real-time analytics and true root cause analysis
  • Complemented by broad infrastructure performance information

 

Network-Aware APM – is another form of data collection because the network is where applications travel, and the network team usually gets called to solve problems first.

apmcomponents5 Network Aware APM 
  • The network is the backplane of modern applications
  • Understand impact of network performance on application behaviour
  • Provides tracing and visibility for ALL applications

 

Analytics – There is a tremendous amount of information as you collect data across 100’s of applications and perhaps millions of transactions.  You need to collect and store that data efficiently to be able to trend, analyze, and solve problems with it

apmcomponents6 Analytics
  • Store and index large amounts of performance data
  • Automatically extract anomalous behaviour, correlate information, identify the root cause of problems, and predict events and performance trends
  • Reveals valuable information to alert staff and resolve problems faster

 

With these 6 elements covered you will have complete visibility and will be able to effectively manage application performance and minimize user impact going forward.

Measuring IPTV Quality

If you’re implementing IPTV, it’s important to know what metrics to monitor to ensure the transmission of high quality video. Managing performance entails more than tracking response time. Let’s look at the key metrics for managing IPTV in the following table:

Performance Area Metric Description
IPTV Service Metrics QoE Video quality of experience measured via Media Delivery Index (MDI), most often displayed as two numbers separated by a colon: delay factor (DF) and the media loss rate (MLR)
Packet loss Defined as the number of lost or out-of-order packets per second. Since many receivers make no attempt to process out-of-order packets, both are treated as lost in the MLR calculation. The maximum acceptable value for MLR is zero, as any packet loss will impact video quality.
Jitter Measures the variability of delay in packet arrival times
Latency Time taken by transport network to deliver video packets to user
QoS Verify precedence settings are the same for all components of IPTV transmission
IPTV System Metrics CPU Amount of CPU available and used
Memory Device memory available and used
Buffer utilization Quantity used and available
Network Metrics CIR utilization User utilization relative to Committed Information Rate (CIR)
Queue drops Queue drops due to congestion

 

With a basic understanding of key metrics and the technical specifications from your IPTV solution, you can set thresholds and alarms on metrics to notify you of potential issues before they impact the user.

5 IPTV Monitoring Best Practices

Chances are you’ve seen Internet Protocol TV (IPTV) but didn’t know it. Different types of IPTV are popping up in our daily lives ranging from Video-On-Demand to being greeted by pre-recorded video messages at the gas pump or ATM. And many businesses are adopting IPTV to broadcast live or on-demand video content to employees, partners, customers, and investors.

But what does this mean for the network team? In this article we’ll outline IPTV basics and focus on primary management challenges and best practices.

IPTV Basics

In regards to your company, IPTV simply means it has systems in place that can send, receive, and display video streams encoded as IP packets. IPTV video signals can be sent either as a unicast or multicast transmission

  • Unicast: involves a single client and server in the process of sending and receiving video and communication transmissions. Video-on-Demand is a great example of this.
  • Multicast: the process of one party broadcasting the same video transmission to multiple destinations. An example would be a retail chain broadcasting the same video to kiosks in all their stores.

Monitoring Challenges & Best Practices

Implementing best practices can ensure IPTV runs smoothly on your network and performance issues are minimized. As IPTV is deployed, make sure your team is doing the following:

  • Get Visibility, Get Resolution: To ensure video quality, monitor at several points along the video delivery path: headend (point of origin), core, distribution, access, and user/receiver. Critical for capturing accurate metrics and isolating problem source.
  • Minimize Delay and Packet Loss: IPTV video quality can often be compromised by small variations in delay or any significant packet loss. Track, baseline, and alarm on IPTV metrics to proactively identify issues.
  • Avoid Bandwidth Surprises: Transporting video across IP infrastructure consumes considerable bandwidth. Monitor regular use to avoid exceeding thresholds and assist in capacity planning. Reduce the impact of outages by confirming backup network paths have required capacity to carry video.
  • Don’t Monitor in a Vacuum: Confirm your existing performance monitoring tools can track IPTV traffic and metrics alongside existing applications. Incomplete performance views will cause your team to waste time attempting to guess IPTV performance or the impact of other applications on IPTV transmissions.
  • Play Nice with the Video Group: On a converged network, troubleshooting any video issue will involve working with the video group. Attempt to establish processes for coordinating troubleshooting efforts, before problems occur.

This article serves as a starting point for understanding IPTV performance challenges and best practices to implement for ensuring success. For more in-depth information on the technologies, critical network preparations, and IPTV monitoring metrics, check out the following resources:

How to Dodge 6 Big Network Headaches

The proper network Management tools allows you to follow these 6 simple tips. This will help you stay ahead of network probelms, and if a problem does occurs you will have the data to be able to analyze the problem.

Troubleshoot sporadic issues with the right equipment

The most irksome issues are often sporadic and require IT teams to wait for the problem to reappear or spend hours recreating the issue. With retrospective network analysis (RNA) solutions, it’s possible to eliminate the need to recreate issues. Performance management solutions with RNA have the capacity to store terabytes of data that allow teams to immediately rewind, review, and resolve intermittent problems.

Baseline network and application performance

It’s been said that you can’t know where you’re going if you don’t know where you’ve been. The same holds true for performance management and capacity planning. Unless you have an idea of what’s acceptable application and network behavior today, it’s difficult to gauge what’s acceptable in the future. Establishing benchmarks and understanding long-term network utilization is key to ensuring effective infrastructure changes.

Clarify whether it’s a network or application issue

Users often blame the network when operations are running slow on their computer. To quickly pinpoint network issues, it’s critical to analyze and isolate problems pertaining to both network and application performance.

Leverage critical information already available to you with NetFlow?

Chances are your network is collecting NetFlow data. This information can help you easily track active applications on the network. Aggregate this data into your analyzer so that you can get real-time statistics on application activity and drill down to explore and resolve any problems.

Run pre-deployment assessments for smooth rollouts

Network teams often deploy an application enterprise-wide before knowing its impact on network performance. Without proper testing of the application or assessing the network’s ability to handle the application, issues can result in the middle of deployment or configuration. Always ensure you run a site survey and application performance testing before rolling out a new application – this allows you to anticipate how the network will respond and to resolve issues before they occur.

Manage proactively by fully understanding network traffic patterns

Administrators frequently only apply analysis tools after the network is already slow or down. Rather than waiting for problems, you should continuously track performance trends and patterns that may be emerging. Active management allows you to solve an emerging issue before it can impact the end user.

Infosim explains how the SaaS model of Network & Services Management can transform your IT operations

 It is really next to impossible to avoid hearing about how “The Cloud” is transforming business everywhere. Well-known technology companies from the old guard like IBM, Oracle, Microsoft, and Adobe, to established tech powerhouses Google and Amazon, to pretty much every new hot startup like Cloudera are all promoting how they are using the cloud to deliver their product using a SaaS delivery model. Infosim® is seeing this trend start to take hold in the Network & Services Management and IT Service Assurance space.

Our customers want to know if they would benefit from using a cloud/SaaS monitoring solution. So, why the big push to SaaS and away from traditional enterprise software sales? Well, from a business standpoint a recurring revenue model is preferred by salespeople and Wall Street alike. It guarantees a revenue stream in the future while also making the customer interactions a little more “sticky” (to use a silicon valley term). But, while that may be great for the technology company, can the same be said for the end-user? Do their customers see an equal, or even greater, benefit from switching from a long-term contract to a more on-demand model? This article seeks to investigate the customer side of the equation to see if the change to SaaS really is a win-win for both the vendor and the customer.

1. Cost

Let’s begin by looking at cost. Make no mistake; the bottom line is always the most important factor in any comparison of delivery mechanisms. If customers can receive the same operations success at a lower price point, they will go that way every time.

The cost analysis can be somewhat complicated because while the entry price is always significantly lower when purchasing software via SaaS, you have to also think about how that cost might add up over time if you continue to use the software for a long period of time. Thankfully, these types of cost analyses have been studied in depth over the last few years and the verdict is very clear, SaaS Total Cost of Ownership (TCO) is lower than the traditional way of purchasing. Most models have come to the conclusion that SaaS reduces total cost (including maintenance, upgrades, personnel, etc.) to between 35% and 50% over the cost of traditional on-premise application systems. This cannot be ignored and is (and will most probably continue to be) the main driver behind the explosion of SaaS deployments.

2. Ease of deployment

The second most popular reason often cited for moving to SaaS is ease of deployment. This really comes down to the fact that when implementing a SaaS model, the end-user typically has to deploy much fewer compute and storage resources vs an on-premise application. Fewer (or zero) servers, databases, storage arrays, etc. This means a smaller datacenter footprint, which means less power, space, cooling, and everything that goes with managing your own datacenter resources. These factors have cost implications in their own right but notwithstanding financial benefits this reduction in infrastructure means a much lower physical burden on the overall IT service organization. Many see this benefit as having an equal if not larger overall impact to the end-user as the pure financial reduction.

3. Increased flexibility

The third-biggest driver of SaaS from the customer point of view is typically thought to be the increased flexibility that this model delivers. Under the old model, once you purchase a software feature set, you are stuck with what you have committed to. If your needs change, you typically have to eat those sunk costs and then buy more/newer features to meet your changing needs. Conversely, with SaaS you can very rapidly turn features on or off, scale up or down and generally make changes to your systems almost on the fly. This makes management much more comfortable committing to a solution when they know that if their needs change quickly, their software vendor can change with them.

4. Availability

 When evaluating any solution, one of the sometimes overlooked but important “abilities” to take into consideration is availability. The concept is simple, if the software is unavailable, then your users cannot get their jobs done. The cost of downtime for manufactures, financial institutions, and most other businesses can be staggering. It can be the difference between success and failure. This is why most companies spend a lot of time and money on creating disaster recovery plans, geo-redundant systems and other solutions to ensure availability. SaaS has an inherent advantage due to the typically large scale of the software solutions global footprint. AWS from Amazon, Azure from Microsoft, and others have spent huge sums of money to build out global datacenters which have more redundancy than a typical organization could afford to build on their own. Even very large companies that could potentially build out these datacenters have begun to move their systems to the cloud when they realize that advantages outsourcing availability.

5. Expertise

 Another consideration that may not come to mind initially is the availability of expertise to help solve issues or drive development of features. When many, many customers are using essentially the same services provided in the same way from the SaaS solution vendor, they tend to encounter the same problems (and find solutions) very quickly. And, those solutions tend to get posted to user community websites or YouTube etc. almost immediately. This means that as an end-user, when you have an issue, you can typically go online and find a fix or training almost immediately. This speeds up time to resolution dramatically.

6. Security

 Many initially see security concerns as a reason against moving to the cloud. They see their very important data as being kept someplace outside their control and open to attacks and hackers, etc. However, the truth is that if you investigate most of the major well-known data breaches over the last few years; you see that the majority of them have happened to organizations that have been breached internally and not via large-scale cloud infiltrations. So many smaller and medium sized organizations do not have the security expertise or budget to effectively block the advanced threats that are commonplace today. In fact, it tends to be the large cloud providers that more effectively create a security moat around important data than a smaller company could. SaaS vendors can apply a critical security patch to all of their customer in minutes, and not have to rely on the end-user downloading and applying the fix themselves. This ultimately creates a much more secure environment for your data.

When combined, both the common features of SaaS along with some of the lesser-known benefits can add up to a complete and very positive transformation of delivering an IT service such as network management and service assurance.
