Best Network Security Tools to Use in 2021 (in addition to a Firewall)

With the continued sophistication and rise in the volume of malicious software and other online threats, the need to use a combination of dependable network security tools is inevitable. Gone are the days when firewalls alone would get the job done.

According to a report released by Purplesec, cybercrimes have risen by a whopping 600% in 2020. Part of this surge fuelled by the pandemic and the increased reliance on IoT for work, learning, shopping and name it. Both personal and work devices are at risk.

To stay protected in 2021, you need a set of security tools in addition to the firewalls. Let’s look at how firewalls function, some of the current risks that they do not offer protection against, and later some of the tested tools that you can use alongside a firewall to strengthen your guard.

Functions of a firewall

A firewall’s main function is to provide network security. This is done by filtering the internet and blocking any suspicious traffic from accessing a secured network.

A suspicious network is determined using preset rules and conditions which vary depending on the method of filtering used by a firewall.

Why a firewall is not enough for network security

Being reactive protection rather than proactive, a firewall has proved to be a good security tool but with the modern-day cyber threats, a firewall alone is not pulling the weight.

If an attacker successfully figures out what the preset terms and conditions for a firewall to block threats are, he can easily devise a way of circumventing the rules. That’s how cybercriminals develop threats such as malware, phishing and DDoS attacks to bypass firewalls.

So, which tools can you use to really protect your network?

Don’t toss away your trusted firewall just yet. It is good, just not sufficient. Consider using concerted efforts between the firewall and the 5 security tools discussed below.

6 tools to secure your network

Network Security

Data breaches are on the rise. Unauthorized access remains the leading cause behind security breaches and accounts for 43% of all global data breaches. This alarming statistic begs the question of whether employees are properly protected, and more importantly if your own network infrastructure is at risk for an attack.

In order to secure critical network and cloud-based infrastructure in 2022, you’re going to need a set of network security tools and policies that apply the Zero Trust approach to prevent unauthorized user access and minimize the attack surface. 

Perimeter 81 takes the complexity out of network security and offers a suite of radically simple network security tools for the modern distributed workforce.

Perimeter 81 Offers:

●     Zero Trust Network Access (ZTNA) – Grant access and permissions only if devices and users are verified. Easily create and enforce security compliance policies throughout your organization.

●     Zero Trust Application Access (ZTAA) – Prevent network security gaps by enabling secured and restricted agentless access for employees, partners, and contractors. 

●     Web FilteringMonitor and restrict which websites employees can access to avoid phishing and other web-based attacks. Protect the integrity and confidentiality of your company with Perimeter 81’s Network Security solutions.

1.      Anti-malware

These are tools designed to detect and block spyware, keyloggers, and other forms of malware that are designed to infect and spread through networks.

When used alongside antivirus software, antimalware can help minimize the spread within an infected network by resolving the malware.

2.      Email security gateways

Email security gateways provide security by monitoring both incoming and outgoing emails within a network. It is a reliable way to counter phishing and other nasty attacks spread through emails.

3.      Virtual private networks

To block eavesdroppers and any other party from spying on your network activity, many people choose to download a VPN on their device. In terms of reliability, Virtual Private Networks are the leading hack-proof security tools for private internet access over a network.

Using this tool gives you the peace of mind: that no one can lay hands on your internet data when it’s in transit.

4.      Data loss prevention software

These security solutions offer protection against data leakage or compromise. They monitor sensitive data whenever it’s in use, inert or motion. This greatly reduces the cases of criminals using human weakness to sneak sensitive data out of a network. 

5.      Endpoint security

The line between personal and work devices continues to grow thinner by the day. Unfortunately, this lack of a clear distinction is risky in the modern-day threats landscape.

With endpoint security, you secure the end-user devices within a network including laptops, smartphones, PCs and so on. This is an ideal way to protect the work network from any vulnerabilities emanating from personal or other non-work devices connecting to the network.

Although we are living in the age of all-new and sophisticated cybercrimes that multiply by the day, pairing the security solutions above with a firewall can go a long way in decreasing the vulnerabilities.
