Best antivirus software for small business

Using the antivirus for enterprise is crucial, no matter the company’s size. Smaller organizations tend to skip investing in malware protection, thus, they become a more potential target for threat actors.

For the malware to spread and steal the organization’s information, it takes only a single unprotected device with access to the database. As of today, the majority of business antivirus programs are cloud-based, maintaining the whole network safe. Regarding machine learning techniques, the threats are detected and stopped quickly across all devices.

However, along with malware protection programs improving, threat actors are continuously taking a step forward too. So, it’s important to select the most advanced protection suite. Consequently, we have tested and selected the best antivirus software for small businesses and their employees. These options offer top-notch security features, easy management, and a great price-to-quality ratio.

Top 5 best business antivirus solutions

Do small businesses need antivirus?

Yes, small businesses need antivirus protection to defend against various threats like spyware, viruses, and malware. Cybercriminals often target small companies due to their limited resources, making them vulnerable to attacks that can result in financial losses, compromised data protection, and operational disruptions.

In 2022 Barracuda Networks studied millions of emails from thousands of companies. They discovered that, on average, a small business employee (less than 100 employees) faces 350% more social engineering attacks compared to an employee in a larger enterprise.

Investing in top-notch antivirus software is essential to minimize these risks and safeguard your business along with client data. Let's explore the leading antivirus options tailored for small businesses.

How to choose an antivirus for business?

Choosing the best antivirus software option is crucial for business owners. With most of your data being online, security is most important. But just blindly picking the most popular or expensive antivirus software isn’t smart. You need to know what features are a must to keep your business safe.

To invest in the best antivirus software option, it needs to cover these main features:

  • Protection against malware. The main purpose of an antivirus is to secure your systems from dangerous viruses or phishing attacks. So, any good provider has to offer software with a high-security score and not flag false-positive attacks. To get an idea of each provider's performance, you can always check independent AV-TEST lab results, as they are held monthly. Also, antivirus should be updated often, to offer the best quality protection. You can search for any relevant updates on each provider's website.
  • Scalability. When selecting antivirus software, it's essential to ensure it can grow with your needs. It should protect your current devices and easily adapt to new ones as your organization expands. You can conduct a search and check which providers can offer antivirus to cover a variety of devices. Additionally, check the options for switching plans as your needs grow and see what plans they offer.
  • Compatibility. Not all antivirus providers offer the same support for different devices. So it’s smart to check before buying the package if it works with your systems. And, if you’re using different iOs, Windows, macOS, and other gadgets, it’s crucial to check if you get the same amount of support for each.
  • Email security. Another important feature to have since a lot of business information goes through email. Securing your email box will prevent data leaks and phishing attacks.
  • A safe browser or VPN. The best antivirus software offers both of these features, but at least one of them is mandatory. This helps protect your identity and activity online. Also prevents from visiting malicious websites.
  • Price. Businesses have a lot of expenses, so blindly choosing the cheapest or the most expensive antivirus software isn’t too smart. You need to pick the provider that is within your budget but still offers the necessary features you need.

Personal vs Enterprise antivirus: what’s the difference?

While some might think that enterprises and individual users can rely on the same antivirus software to protect their devices and data, the reality is a little different. Enterprise and personal antiviruses are not the same, and here are some of the most significant differences:

  • Management. While a consumer antivirus control panel is usually easy to navigate, and the product is ready for use once installed, enterprises most often have more than one device to protect. Moreover, these devices are connected to one network, and each is regarded as an endpoint of that network. Thus, enterprise security requires more sophisticated management which often involves a control panel in the cloud that provides an overview of the whole business network.
  • Features. Enterprise antiviruses often have a lot more advanced security features, which may include internet security for businesses, and sophisticated endpoint security. They often include machine learning and behavioral analytics to catch advanced threats and prevent data breaches.
  • Versatility. While consumer antivirus software may be available for the most common operating systems, an enterprise antivirus has to be compatible with a great variety of devices, cloud services, servers, and more.
  • Cost. Enterprise antivirus will always be a lot more expensive than personal antivirus software, simply because it is much more complex, more difficult to maintain, and requires more advanced security solutions.


Security is crucial for small businesses as they often overlook investing in malware protection, making them more susceptible to threats. It's essential for them to use antivirus software, but finding the right fit can be tough. Each company has unique requirements based on industry, employee count, and data sensitivity. Therefore, choosing a reliable antivirus is vital to safeguard the company and its employees' and clients' information.

Our tests showed that the top pick for small businesses is Norton Small Business robust protection suite that covers up to 205 devices. It stands out with easy-to-set up apps and real-time solutions for various phishing attacks and malware.
