Comparison of the best antivirus for small businesses

Business antivirus software is a type of security measure meant to protect a company’s devices, network, and sensitive data from potential cyber-attacks, malware, and viruses. Without such software, the data and devices are exposed to potential hacking attempts, which can jeopardize the business itself. Thus, specialized antivirus software must provide advanced threat protection, centralized management, and robust network protection capabilities not usually found in standard personal antivirus software.

Every business antivirus is tailored to different needs and types of businesses, so it is really important to make an informed choice before choosing the right software for your business. It is best to carefully evaluate each option’s features, pricing, and suitability for your individual case. So, before I jump to detailed descriptions of my top antivirus for small business choices, I’ll provide you with a comparison table where you can easily see the core features of my top choices side-by-side. These highlighted points will make it easier to choose the right service for your business.

How to choose the best antivirus for your business

Choosing the best antivirus for your business can be complicated if you’re uncertain about the main criteria to look for or the steps to take in preparation. To make the task less problematic, I’ve compiled a list of how to choose the most suitable antivirus for your business.

1. Learn your vulnerable spots. Asses and inspect your current cybersecurity measures. If you see any weak spots, you’ll know clearly where your chosen antivirus software should excel to glaze over the cracks.

3. Consider your budget. Check your available funds and choose the right price-to-feature package so the purchase will not affect your overall operation.
4. Plan time for trial. Before you finalize the software purchase, plan a trial period during which you’ll need to check how the cybersecurity solution integrates with existing workflows, how easy it is to use, and how well the features work.

Key features to look for in a small business antivirus software

Undoubtedly, the effectiveness of antivirus software depends on its reliability, protection scope, and how well it works at detecting malware. Here are the key features to look for in a small business antivirus software:

1. Robust malware protection. Any small business antivirus software should have 3 layers of protection: file, network, and application. Additionally, USB protection and employee and network tracking are very important, too. You can find all of these features in the TotalAV, which is a great choice for small businesses looking for comprehensive cybersecurity.
2. Performance impact. Choose software that won’t hinder your day-to-day operations. Look for stats on boot timings and scan speeds. All of my recommended AV solutions run light, but if you want something near-invisible performance with lightning-fast scans, Norton AV and Bitdefender are the best choices.
3. Reliability. A reliable cybersecurity solution, such as an antivirus, must be regularly updated to protect your devices reliably. So, look for software that updates itself automatically and has a constantly evolving threat library.
4. Performance. The software needs to be accurate in malware and threat detection. You can check the performance stats in this article from our in-house testing or third-party organizations, like AV-Comparatives for their take on popular AV solutions. As for my top picks, TotalAV and Norton AV were the best-performing software with close to 100% detection accuracy.
5. Simultaneous connections. Depending on the size of your business, choose software that offers enough device coverage. For instance, Norton Small Business package and Malwarebytes antivirus are absolutely perfect for small businesses with 20 devices covered, while Bitdefender GravityZone offers a coverage of up to 100 devices.
6. Usability. Choose software that’s easy to use and will be much easier for your employees to use it. The best choice is TotalAV, which has a user-friendly interface and takes no time to master.
7. Customer support. For a well-rounded service, look for an antivirus software brand that offers 24/7 customer supports you can reach via various channels, including live chat, emails, and phone lines. If that’s the key point for you, choose Nord Threat Protection as it has possibly the best and most responsive customer support in the industry.

How to install antivirus on all business devices?

Some small business antivirus software first require installation on the administrator machine. For example Bitdefender GravityZone operates as a client-server solution managed by a single Control Center. this means, it must first be installed on an agent device from which other devices can be easily added, monitored, and controlled.

However, TotalAV, Norton Small Business, Malwarebytes, and Surfshark One offer a more straightforward setup and can be installed just like regular antivirus software. For example, here’s how to install TotalAV:

1. Purchase a TotalAV subscription

Do small businesses need cybersecurity?

Small businesses face a significant threat of data breaches, ransomware, phishing, malware, and DDoS attacks without a cybersecurity solution. Out of all industries, healthcare, finance, and retail are the most vulnerable to malicious actors' actions.

According to statistics 43% of all cyberattacks target small businesses. However, only 14% of them have viable cyberprotection plans. This is one of the main reasons why small companies become prey to bad actors. And while numerous threats are imposed on such businesses, ransomware alone is a major threat, with the median loss per breach mounting up to $46,000.

Phishing attacks are just as dangerous for small businesses with a tendency of compromised credentials exploitation reaching an incredible 80%. Without antivirus protection, small businesses are especially vulnerable to malware delivered through phishing emails, exploited vulnerabilities, and malware.

However, the most alarming thing is that 60% of small businesses shut down completely within six months of a data breach or a cyberattack. Meanwhile despite these incredibly high risks, many companies still underestimate the need for cybersecurity tools. At the same time, a combination of a firewall, antivirus, and a VPN could easily safeguard their sensitive data and systems, while ensuring business continuity.

Other ways to protect your business from cyber-attacks and malware

Besides small business antivirus software, there are also other ways to protect your business from common cyberthreats. Of course, they work the best when in conjunction with an antivirus and it’s a good idea to employ multi-pronged tactics in safeguarding your business:

• Create a solid cybersecurity plan. Create and stick to a plan that includes regular backups, security policies, and timely software updates.
• Use a VPN. A Virtual Private Network, or a VPN like NordVPN, encrypts all your network traffic to provide another layer of security to your business. It is especially useful with remote employees who might want to connect to unsafe public Wi-Fi.
• Educate your employees. Train your staff to recognize suspicious emails, links, sites, and pop-ups to prevent possible data breaches.
• Install a firewall. Use a firewall to further protect the connection between your network and outside devices.
• Encrypt sensitive data. Use encryption to protect sensitive data, such as passwords and never send it out in emails unencrypted.
• Use interception proxies. These proxies reliably block all known malicious sites from reaching you.
• Employ safe browsing lists. This way, you or your employees won’t be able to enter any known malicious sites.
• Rely on network access control. Alternatively known as NAC, this is a handy tool in protecting your business from cyberthreats.

Remember that while all these alternatives are great in improving the cybersecurity of your business, they all work the best when combined with a reliable antivirus software.
