Top 5 features of a Network Traffic Analysis (NTA) tool- Why you need Stealthwatch now more than ever

According to research from Enterprise Strategy Group (ESG) and the Information Systems Security Association, 91% of cybersecurity professionals believe that most organizations are either extremely or somewhat vulnerable to a significant cyber-attack or data breach.1 CISOs have tried many different solutions. Many are increasing hiring in a field with a steep talent shortage, which may have some long-term returns but doesn’t solve the problems they are facing today. Some also purchase a patchwork of security solutions that aren’t really integrated – an approach that can cause major complications for security architects. These strategies are clearly not increasing confidence in their overall security effectiveness.


What are the primary reasons you believe cybersecurity analytics and operations are more difficult today than they were 2 years ago?

Research indicates that organizations can’t hire their way out of their cybersecurity woes. CISOs must improve security efficacy, streamline operations and bolster employee productivity, and they must rely on their existing workforce. That’s where Network Traffic Analysis (NTA) tools can provide a cybersecurity quick-win. An effective and modern NTA solution can continuously monitor the network and detect threats that might have bypassed the perimeter or even originated within the business. Top-tier NTA solutions take the weight off of the employees’ shoulders by giving them the tools they need to speed up threat detection and remediation. To help you evaluate an NTA solution effectively, let’s take a look at the top features identified by cybersecurity professionals as part of the research conducted by ESG:

1. Built-in analytics and threat intelligence services

44% of survey respondents said that built-in analytics to help analysts detect suspicious/malicious behavior is one of the most important features. Best-in-class NTA tools have different algorithms and signatures built-in to model behavior and crunch data, allowing for high-fidelity alerts that streamline workloads and accelerate incident response. The same percentage also said that threat intelligence services/integrations to enable comparisons between suspicious behavior and known threats is another top feature. These integrations allow NTA tools to “enrich” network telemetry, making alerts more thorough and actionable.

2. Ability to monitor IoT traffic/devices

Users also need the ability to monitor niche equipment that is unique to their industries. This is especially important in industries that have made aggressive investments in IoT like healthcare, manufacturing and transportation. IoT devices generate telemetry and increase the threat surface like any other connected device, and therefore need to feed into an NTA tool.

3. Ability to monitor all network nodes

37% of respondents stated that alerts for when new network nodes are connected are essential for an NTA tool. This means security professionals want NTA tools to issue alerts when unsanctioned devices connect. This is incredibly important for monitoring and mitigating cyber-risks.

4. Proven integrations with other security technologies

37% also said that one of the most important features is documented and tested integrations with other types of security technologies. These other technologies could be malware sandboxes, network segmentation enforcement technologies and much more. These integrations allow for a closed-loop process that includes network security development, monitoring and enforcement.

5. Public cloud visibility

More than a third of respondents said that the ability to monitor cloud traffic is an essential feature. In order to provide true end-to-end visibility, NTA tools need to be able to tap into VPCs, cloud monitoring logs and APIs across AWS, Azure, GCP, etc.

Cisco Stealthwatch


Stealthwatch aligns well with the most important NTA attributes cited by the surveyed cybersecurity professionals. For example, Stealthwatch:

◉ Features multiple types of built-in analytics. Its behavioral modeling and multi-layered machine learning algorithms can detect hidden threats- even those hiding in encrypted traffic.

◉ Provides comprehensive visibility. In addition to monitoring on-premises environments, Stealthwatch also offers agentless visibility into the public cloud. It can also detect when a new network node connects, monitor traffic from IoT devices and more. Nothing slips through the cracks with Stealthwatch.

◉ Backed by Cisco Talos threat intelligence. Threat intelligence is one of the most important features of an NTA tool. Stealthwatch ties its multi-layered analytics with global threat intelligence from Talos, the largest non-governmental threat intelligence organization in the world, and can take immediate action when activity is associated with a known threat, no matter the origin.


CISOs of the world can’t keep up with their security workloads, especially with a global cybersecurity talent shortage. They need quick wins– fast, efficient and accurate alerts that allow them to focus on what really matters. Cisco Stealthwatch is the tool they need right now.
