10 Best Network Security Software & Tools for 2023

In sprawling enterprise networks, you’ll find a variety of software, hardware, users, and tools, and almost as many points of access that can be breached. Network security is the blanket term for the steps your network administrators take to protect all of these features of your network, both from external and internal threats.

To help network administrators that need to build and enforce security measures, several software companies offer network security software and tools to automate and optimize this process. Read on to learn more about your network security options and some of the top network security software providers in the field.

A Glossary of Network Security Approaches

To help you identify what features you’ll need to look for in your unique network security search, take a look at this brief summary of different network security approaches on the market:

  • DNS Security: a type of security that focuses on securing the actions of network users when they visit domains/IP addresses. Content filtering, malware and ad blocking, and typo correction are all examples of this type of security.
  • Firewalls: monitoring tools that watch incoming and outgoing traffic on the enterprise network and filter out unwanted traffic from outside networks. Firewalls can come in hardware, software, and cloud formats. 
  • Zero Trust: this software accompanies zero trust policies, enforcing more authentication requirements and stopping lateral movement across the network when a breach does occur. 
  • Intrusion Detection and Prevention Systems (IDPS): these tools alert your network administrators when possible issues or apparent attacks are affecting the network. IDPS tools check for malware and socially engineered attacks.
  • Network Access Control (NAC): these tools manage access to the network via methods like policy lifecycle management, security posture checks, and guest networking access management.
  • Antivirus/Antimalware: these tools enforce antivirus update policies, but they also take steps to prevent, look for, and remove viruses and malware from the network. 
  • Network Detection and Response (NDR): these tools monitor east-west traffic on the network to identify anomalies in network activity that could pose a threat.
  • Extended Detection and Response (XDR): moving beyond endpoint detection and response (EDR), XDR detects and responds to threats across endpoints, cloud computing, email, and other possible points of entry.
  • Network Security Policy Management (NSPM): these tools help network administrators to manage compliance policies via network workflow documentation.
  • Software-Defined Perimeter: this approach to perimeter security focuses on software instead of hardware, further obscuring hardware like servers to anyone outside of the network.
  • Virtual Private Network (VPN): a VPN provides a virtual access point for users to connect securely to a network server from anywhere. The two primary options are IPSec and SSL.
  • Network Traffic Analysis: this type of tool helps you to spot protocols and applications that run on your network and to track metrics like bandwidth use.
  • Network Sandboxing: when this type of software encounters suspicious network activity, it transfers that traffic information to a sandbox where threat scores are determined.

How to Choose Network Security Software

Price Point

Network security products come with a range of capabilities, but they also come at a wide range of price points. Figure out your must-haves and top priorities, do your research on the companies that excel in those areas, and determine if their payment plan works for you.

Although security portfolios that cover several types of security look appealing and create diverse protections for your network, they can also be incredibly expensive and may offer features that small and medium-sized enterprises (SMEs) will never use.

Support and Customer Service

Before you select a network security tool, it’s a good idea to look at their customer reviews, especially in the realm of customer support. Is customer support included with your purchase, or is it an extra cost? Do you have direct access to their agents, a library of resources, and/or a forum of other enterprise users when you have questions or problems? These are important questions to answer before you make your purchase so you’ll know how to use the tool beyond its initial launch.

Offerings and Integrations

Many network security tools specialize in one niche area of security, but in several of those cases, they offer integrations with other security tools to round out your network defenses. Take a look at what’s natively offered in network security tools, the advances or new features that they’ve added in recent years, and any existing partnerships or integrations that they offer. Although every network security software option is a little bit different and might not exactly fit what you need, you can usually find a way to build it into a solution that works optimally for your network.
