With such advanced cybersecurity solutions, there is no need to continually update your security tools, giving you peace of mind and allowing you to focus solely on your business goals.

But before we get to the best network security tools and types on the market, let’s get to know what network security really is and what type of protection and benefits it offers its users. 

What is Network Security? 

Network security is an imperative necessity for any modern business or individual. It is the process of proactively monitoring, preventing and responding to unwanted access to your digital assets and network traffic. This means employing various hardware and software technologies such as up-to-date firewalls, encryption tools, antivirus tools, IP whitelists, analysis techniques, intrusion detection systems and many more. These countermeasures are essential in order to prevent compromising your networks from potential threats such as frauds, scams, viruses, or malware attacks coming from both known and unknown sources. 

In addition, specialized security personnel such as security analysts and hunters greatly help tackle the intricate challenges associated with fine-tuning your network’s defences on a daily basis. To sum it up, network security refers to a collection of tactics that are designed to protect one’s digital resources against constant threats plaguing the digital world today.

The Benefits of Network Security

Numerous network security tools and resources are there to assist a business in safeguarding its confidential data, improving efficiency and credibility, and bolstering overall business capacity. Check out the following key advantages of network security:

Data Protection

Safeguarding against unauthorized access to your network is crucial, especially with sensitive customer data at risk. Implementing network security ensures protection against hacking and keeps your valuable information hidden from prying eyes. Protect your network and preserve the safety of your customers’ data with reliable network security.

Prevention of Cyber Threats

Cyber threats have become a daunting problem in today’s day and age. Hackers are always on the prowl, inventing new methods to attack and deploy malware. If your network security happens to be weak, the flow of information over the net may be tampered with. Thankfully, network security tools can help protect both your systems and networks.

Centralized Control 

Unlike desktop security software, network security software is controlled by a network administrator. Viral attacks pose a significant threat to the network, making it more vulnerable. However, centralized control ensures that the network remains hack-proof.

Types of Network Security Tools and Techniques 

Network Security

Before you decide on the network and cyber security tool you will be using in your fight against data breaches and all kinds of cyber threats, you must first familiarize yourself with the different categories and types of network security tools and techniques out there and what each of them can offer you. This way, you can make an informed choice of the right type of tool that can guarantee you the level of protection your network needs. 

To help you make this decision, here is an overview of the main types of network security tools: 

1. Firewalls 

A firewall is your digital fortress, the first (and many would say the most important) line of defence against malware, viruses, and other threats. It works tirelessly to scrutinize and filter both incoming and outgoing data to keep your system safe. And if that’s not enough, you can even customize rules and policies to fit your individual needs. So, you easily create exceptions and let specific apps pass through your network’s digital barricade without triggering any false alarms. Your cyber security is fully in your hands.

2. Antivirus Software 

Antivirus software works by scanning files from any source and detecting any potential threats. When it identifies something shady or scary, it can remove or isolate the affected file. While antivirus software isn’t foolproof, it plays a critical role in cyber security. With so many options to choose from, ranging from free to hundreds of dollars, you’ll want to find the right one to safeguard your system. Remember, even though zero-day threats can still be an issue, installing antivirus should be part of your cybersecurity baseline.

3. Anti-Spyware Software

Spyware is a notorious cyber threat that operates covertly to monitor users’ online activities and intercept personal information, including passwords and confidential data. However, anti-spyware software serves as a powerful combatant, ideally safeguarding against malicious apps like key loggers and password recorders.

4. Access Control 

By granting or limiting access to your network, you can greatly reduce the potential damage that cybercriminals can inflict. Remember, it’s not just the dodgy outsiders who pose a threat: even authorized users can accidentally or maliciously harm your system. Access control helps you take back the reins by permitting individual users access only to network areas that are crucial to their role, allowing you to bolster security while maintaining operational efficiency.

5. Virtual Private Network (VPN)

Virtual Private Network (VPN) security tools validate communication between a secure network and endpoint devices. Encrypted, remote access VPNs typically utilize IPsec or Secure Sockets Layer (SSL) to authenticate and prevent eavesdropping. Don’t let cyberstalkers or hackers penetrate your network; beef up your online defences with a VPN.

6. Data Loss Prevention (DLP)

The human element is often the weakest link in network security. As a matter of fact, staff and other users may inadvertently compromise sensitive data or leak it out of the network. This is where DLP technologies and policies come in to protect you from such data mishaps.

7. Email Security 

Similar to protecting against DLP vulnerabilities, email security aims to mitigate human-related security weaknesses. By employing complex phishing strategies, attackers dupe email recipients into sharing sensitive information via desktop or mobile devices or unwittingly downloading malware into target networks. Besides detecting hazardous emails, email security can prevent attacks and stop the sharing of critical data. With email security, you can guarantee that you won’t fall for sneaky tactics used by malicious actors on the web.

8. Security information and Event Management (SIEM)

Aggregating relevant data from diverse tools and resources can often be a formidable task, particularly with time constraints. However, Security Information and Event Management (SIEM) tools provide responders with a comprehensive overview of data, resulting in quick and effective action. 

9. Anomaly Detection Engines (ADE)

One of the most common yet frustrating challenges in network security is identifying anomalies without a baseline knowledge of how the network operates. However, Network Anomaly Detection Engines (ADEs) come to the rescue by providing a comprehensive analysis of your network’s performance. The best part is that when security breaches occur, ADEs send quick alerts to help you respond swiftly and strengthen your system.

10. Endpoint Security

Catering to the growing trend of Bring Your Own Device (BYOD) in the business world, the distinction between personal and business computer gadgets is blurring. While accessing business networks via personal devices can make them more vulnerable targets, endpoint security provides an additional security layer to protect your business networks from any unwanted interference originating from remote devices.

11. Intrusion Prevention Systems (IPS)

IPS technology plays a vital role in safeguarding networks from potential security threats. With the ability to detect and prevent brute force attacks, vulnerability exploits, and Denial of Service (DoS) attacks, IPS ensures secure networking. Vulnerabilities are weak spots within software systems, which can lead to exploitation through these security breaches. Attackers exploit these vulnerabilities by taking advantage of the patching delay window that occurs after exploits are announced. By employing an Intrusion Prevention System, network security is enhanced, blocking these attacks efficiently and effectively.

12. Cloud Network Security

As technology advances, the traditional data centre approach is steadily fading away. Rather, hosting applications and workloads in the cloud is at the forefront. However, the challenge of keeping up with the migration of application workloads requires innovative solutions. Enter; Software-defined Networking (SDN) and Software-defined Wide Area Network (SD-WAN) solutions. Integrating these technologies offers the much-needed flexibility to protect the modern data centre since they support network security in private, public, hybrid, and cloud-hosted Firewall-as-a-Service (FWaaS) deployments.
