  • 🥇 Bitdefender

    : Bitdefender GravityZone antivirus business suites include endpoint protection, device and application control, a strong firewall, mobile protection, and more. Each plan is competitively priced and even includes the option to purchase individual features.

Many small business owners believe their businesses aren’t big enough to be interesting to hackers. However, the truth is quite the opposite: due to their minimal or non-existent cybersecurity infrastructure, small businesses are actually prime targets for cybercriminals. Picking the right antivirus can mean the difference between staying secure and facing lost revenue, legal damages, and reputational ruin.

In this article, you’ll find the top 5 antivirus solutions for businesses in 2025. These options don’t just block viruses: they offer full protection against malware, ransomware, phishing, and other cyber threats, along with key features specific to business environments.

I examined each antivirus’s malware detection, performance impact, extra security features, ease of use, and whether they can grow with your business. Bitdefender stands out as the most versatile and comprehensive solution, with top-notch security features and competitively priced plans for businesses of any size — but the other products I recommend are also strong contenders. Whether you’re running a small business with just a few devices or managing IT for a large corporation, this list will guide you to make the best choice.

🥇 1. Bitdefender — Best Overall Antivirus for Businesses of All Sizes in 2025

🥇 1. Bitdefender — Best Overall Antivirus for Businesses of All Sizes in 2025

Bitdefender is my favorite antivirus for both small and medium-to-large businesses in 2025 — it provides advanced security for computers, mobiles, and networks, is easy to use, and doesn’t negatively impact the performance of a device.

Its lightweight and effective malware scanner uses a combination of cloud-based technology, traditional signature-based scanning, and machine learning to catch even the types of malware that are most difficult to detect and eradicate, such as rootkits and trojans.

Bitdefender also has various other features that can protect both in-office and remote workers. Its cloud-based centralized management console allows administrators to deploy, configure, and manage security policies across all devices, whether on-site or remote, making it easy to monitor and protect all endpoints.

From the dashboard, it’s easy to assess any issues with your security configurations and modify them accordingly, since Bitdefender provides you with a prioritized list. I found the list really simple to understand and use, and it was great to get a clear picture of what needed fixing and how urgent or otherwise each fix was.

Users who don’t have an IT expert among their employees will appreciate that Bitdefender makes installing security agents on remote devices easy; you don’t even need access to the endpoint to deploy the antivirus.

Bitdefender provides a wide range of basic and advanced features suitable for small, medium, and large businesses. Some additional features that Bitdefender offers include:

  • Firewall. Monitors and controls your inbound and outbound traffic.
  • Network security. Prevents unauthorized access to your business network.
  • Web and exploit protection. Shields you from phishing, drive-by downloads, and zero-day exploits.
  • Threat intelligence solution. Managed through the IntelliZone cloud portal, it gives your business insight into global threat data and malware sandboxing.
  • Endpoint risk analytics, detection, and response. Monitors endpoint activities, identifies potential vulnerabilities, and fixes issues.
  • Application and device control. Manages and restricts application and device usage, preventing unauthorized software installation and controlling peripheral device access, such as USB drives.
  • Sandbox analyzer. Isolates and tests suspicious files in a secure virtual environment.
  • MITRE event tagging and anomaly defense. Uses advanced threat detection techniques aligned with the MITRE ATT&CK framework to identify and respond to sophisticated cyber attacks.
  • Root cause analysis. Trace the origin and progression of security incidents.

Bitdefender offers a number of plans, including Bitdefender Small Office Security, which is great for small businesses. Bitdefender GravityZone Business Security Premium is a fantastic option for medium and large businesses that require more advanced protections, including endpoint security. Finally, there’s Bitdefender’s highest-tier plan, GravityZone Business Security Enterprise, which is the only one that provides access to MITRE event tagging and manual sandbox investigation.

There are also plenty of add-ons available for the GravityZone plans, so you can tailor them with things like full disk encryption, email security solutions, or patch management to suit your business’s needs. I particularly like GravityZone Security for Mobile Devices — it uses on-device machine learning to protect physical and virtual endpoints on Android, iOS, and ChromeOS, and it can integrate with MDM (mobile device management) solutions.

All of Bitdefender’s plans are very reasonably priced, starting from £27.99 / year. There are annual plans available for 1, 2, or 3 years, and businesses can select the number of devices and servers that require protection. All of Bitdefender’s business plans include a 30-day money-back guarantee, and there’s also a 1-month free trial for those who want to test the software before they buy it.

Bottom Line:

Bitdefender offers excellent security solutions for businesses of any size. It is one of the most effective, lightweight, and easy-to-use antivirus programs on the market, with a wide range of security tools that are suitable for all business types. Bitdefender is very affordable compared to other business antiviruses, and it offers flexible subscription options — making it great for growing companies. All Bitdefender plans are backed by a 30-day money-back guarantee.

🥈 2. Norton — Best Antivirus for Small Businesses With Easy Setup

🥈 2. Norton — Best Antivirus for Small Businesses With Easy Setup

Norton offers an excellent small-business solution — Norton Small Business — that is highly effective and easy to set up. Getting started with Norton Small Business is incredibly simple, with lots of guidance during the entire installation. It’s also super simple to upgrade from a personal Norton account to Norton Small Business, which is handy if you’re already a Norton user.

Like Bitdefender, Norton’s malware scanner combines various detection methods, including a comprehensive malware directory, heuristic analysis, and machine learning. Norton caught 100% of my malware samples in my tests, including trojans, keyloggers, rootkits, spyware, potentially unwanted programs (PUPs), and ransomware. The real-time scanning technology didn’t negatively impact my device performance during setup and testing either.

Norton Small Business also addresses the unique security challenges posed by remote work:

  • Cloud-based management portal. This intuitive online portal lets you remotely deploy and manage security for all endpoints — including those used by remote employees. Administrators can access and adjust settings from anywhere, ensuring comprehensive oversight of devices regardless of location.
  • Automatic updates and Windows optimization tools. Norton provides automatic security updates to all devices to minimize vulnerabilities in remote environments and keeps your business Windows PCs optimized.

Along with these features, Norton Small Business includes essential protections like:

  • Real-time protection — against spam and social networking scams.
  • Wi-Fi security — for employees connecting to unsecured networks while working remotely.
  • Web protection — includes a secure browser with anti-phishing and banking protection and Download Insight, which warns employees against risky downloads.
  • Password manager — for securely storing login credentials.
  • Cloud backup — protects your data from ransomware, theft, or hard drive failures.

Norton’s online device management hub makes it simple to onboard or offboard employees — just email the employee from the portal, and they’ll follow straightforward instructions to add their device to the Norton plan. For larger organizations, Norton’s parent company, Symantec, offers a more advanced endpoint solution with additional features like threat remediation and SaaS asset protection.

Norton also has great customer support, which is available 24/7 to help resolve malware-related issues. Customer support can even freeze access to lost or stolen devices at any time.

Norton Small Business offers annual subscriptions for 6, 10, or 20 devices, starting at £69.99 / year. Norton also offers businesses the option to add new features as they’re required, which is great because it means you don’t have to pay for any protection that you won’t use. All Norton annual subscription purchases include a 60-day money-back guarantee.

Bottom Line:

Norton Small Business is an easy-to-use product for start-ups and small businesses. It’s a cloud-based service with easy deployment and device management, which is perfect for small businesses as an IT department isn’t necessary for implementing it.

🥉 3. ThreatDown (Powered by Malwarebytes) — Innovative Tools for Dedicated Server Protection

🥉 3. ThreatDown (Powered by Malwarebytes) — Innovative Tools for Dedicated Server Protection

Malwarebytes has recently rebranded and split into 2 units. Malwarebytes, the first unit, is marketed toward consumers and smaller businesses, while ThreatDown, the second unit, is predominantly marketed to larger firms.

ThreatDown (powered by Malwarebytes) takes a proactive approach to combating malware. Its malware scanner employs heuristic analysis to detect previously unknown malware strains. All plans also include:

  • Remote deployment and management. Malwarebytes security can be deployed and managed on endpoints you don’t have physical access to, including those in-house and on your remote employees’ computers.
  • Cloud-based endpoint protection. ThreatDown provides consistent security across all endpoints — including those used remotely — via a cloud-managed platform. This allows for unified security policies and protections on all company devices.
  • Real-time threat monitoring. ThreatDown’s platform gives administrators real-time insights into threats and incidents on all endpoints, enabling swift responses to potential security issues.

Depending on your plan, ThreatDown also includes::

  • Ransomware, zero-day exploits, and phishing protection.
  • Threat remediation.
  • Patch management.
  • Windows ransomware rollback.
  • DNS filtering.

ThreatDown comes with innovative tools, including Flight Recorder, which lets you search event data over the last 7 days for all endpoints, meaning you can hunt down or analyze any security issues that might occur. Flight Recorder lets you search files, registry, networking, and processes (and these different types of events are color-coded to help you interpret the report easily).

ThreatDown doesn’t require a dedicated IT team to manage, as it’s exceptionally lightweight and user-friendly. However, a notable downside of ThreatDown is that mobile protection is available only as relatively pricey add-on.

The most basic plan, ThreatDown Core, starts at £56.31 / year per endpoint. There are also more advanced protection plans — Advanced starts at £64.47 / year per device, while Elite starts at £80.79 / year per device and adds managed detection and response. The most comprehensive plan, Ultimate, costs £97.11 / year per device and brings malicious website filtering to the table. Every plan has optional add-ons for mobile and server protections.

Bottom Line:

ThreatDown (powered by Malwarebytes) is a simple cybersecurity program with dedicated solutions for servers. It has a decent range of features, providing both small and medium-sized businesses with good antivirus protection.

4. Intego — Best Antivirus for Mac-Based Businesses

4. Intego — Best Antivirus for Mac-Based Businesses

Editors’ Note: Intego and this site are in the same ownership group.

Intego is my favorite business antivirus solution that is tailor-made for macOS. Its offerings include an antivirus protection suite, a network security suite, and advanced Mac optimization tools.

Intego can protect both in-office and remote employees with features like:

  • Two-way firewall protection (NetBarrier X9) — adapts to home, public, and work networks, providing smart two-way firewall protection. This means employees are shielded against network-based threats, no matter where they connect from.
  • Real-time malware protection — continuously monitors for malware threats, including those that may be introduced via unsecured public Wi-Fi networks — a common risk for remote workers.

Intego effectively detected and removed various malware types, including ransomware, trojans, adware, and rootkits, without impacting my Mac’s performance. The scanner is fast and efficient, using file caching to skip previously scanned files and saving valuable time.

Intego also has effective optimization tools that can help you keep your files and folders organized and remove duplicate and junk files. It’s a useful feature, but I wish Intego also included a system speedup tool.

However, the biggest downside is the lack of a centralized management hub. More advanced business-oriented features such as remote deployment, server encryption, patch management, or network security are also missing from its bundles. Finally, there’s no phishing protection and all the plans are Mac-only (although you can connect your business iPhone to a Mac and run a scan on it as well). Businesses with more extensive needs may want to consider options like Bitdefender or Kaspersky.

All of Intego’s plans can be bought directly from the official website if you just need protection for up to 5 Macs. If you have more business devices than that, you can reach out to Intego’s sales team for a quote. Intego’s plans come with a 30-day refund policy.

Bottom Line:

Intego is a market leader for Mac device security, and its business offerings are a good choice for companies that primarily use Macs. Intego provides both antivirus and network security, and custom plans can be created to include Intego’s optimization tools.

5. Kaspersky — Best Antivirus for Small-to-Medium-Sized Businesses

5. Kaspersky — Best Antivirus for Small-to-Medium-Sized Businesses

Kaspersky has a great anti-malware scanner, combining a malware database and cloud-based machine learning to detect the most recent threats. Similar to Bitdefender, Kaspersky’s malware scanner caught a large number of the malware samples I hid throughout my PC, including rootkits, keyloggers, trojans, ransomware, and others.

Kaspersky’s Small Office Security offers some core security capabilities for businesses with up to 49 employees:

  • Centralized management console — the web-based console allows administrators to add or remove endpoints, review alerts, and update devices remotely, so both in-office and remote endpoints have consistent protection.
  • Full endpoint protection — protects desktop and mobile devices with an antivirus, web protection, and a firewall.
  • Vulnerability and patch management — to keep systems up-to-date and close any potential vulnerabilities.
  • File server protection — protects your servers by encrypting them, backing up the data on them, and checking them for malware.

More useful features are available as add-ons or on more expensive plans:

  • Password manager (Small Office Security add-on).
  • VPN (Small Office Security add-on).
  • Sophisticated threat analysis and reporting.
  • Unified security policies.
  • Device control.
  • Cloud security for Office 365.
  • Online security training on incident response and threat detection for IT teams.

Kaspersky has 3 business plans for small to medium businesses (enterprise-level solutions are available, too). The simplest one is Small Office Security, which doesn’t require IT expertise to implement and maintain. It starts at £57.55 / year for 3 users (the maximum is 49), which translates to 3 desktop and 3 mobile licenses.

There’s also Kaspersky Next EDR Foundations (, 5–99 employees £174.95 / year), with cloud monitoring, security policies, device control, and threat analysis, as well as Kaspersky Next EDR Optimum (£395.04 / year, 5–99 employees), which adds advanced threat analysis and IT personnel training. All plans include a 30-day trial and are backed by a 30-day money-back guarantee. Unfortunately, due to regulatory reasons, Kaspersky cannot be sold to US customers.

Bottom Line:

Kaspersky is a secure, reliable antivirus with a wide range of business solutions for businesses of all sizes. All of its business plans are scalable depending on your company’s IT management and needs.

Testing Methodology: Comparison & Ranking Criteria

I followed our comprehensive testing process to find and rank the best antivirus solutions for businesses in 2025. My evaluation included analyzing malware protection, ease of use, business-specific features, multi-device coverage, value, and advanced solutions for modern security challenges. Each product on this list excelled in real-world tests, surpassing its competitors. Here’s a breakdown of the criteria I used:

  • I tested malware detection rates and security capabilities. I looked at each antivirus’s ability to defend against advanced threats like ransomware, spyware, and rootkits. Additionally, I checked for solutions that included endpoint protection, essential for securing multiple devices on a business network.
  • I considered remote work security challenges. I looked for antivirus solutions offering advanced endpoint protection, VPN integration, and remote management capabilities to secure off-site employees. As remote work increases, protecting the expanded security perimeter is essential for businesses.
  • I evaluated ease of use across different user types. I tested each software’s interface and features to ensure that technical and non-technical users could easily navigate it. I paid special attention to whether these solutions were appropriate for businesses of varying sizes.
  • I assessed business-focused features. I checked for administrator tools, sandboxing options, and the strength of the firewall. I also looked at each product’s ability to detect and protect against unsecured Wi-Fi connections, which is increasingly important as more employees work remotely.Testing Methodology: Comparison & Ranking Criteria
  • I tested for multi-device coverage. I ensured each antivirus solution could protect various devices, including PCs, Macs, smartphones, and tablets. I also reviewed whether the plans offered by each provider were scalable enough to grow with a business’s needs, with solutions like Bitdefender standing out for their mobile security offerings.
  • I evaluated regulatory compliance and reporting features. Many businesses must comply with industry regulations such as GDPR, HIPAA, or PCI DSS. I sought solutions that offer compliance support through detailed reporting and data protection tools to help companies meet their regulatory obligations.
  • I evaluated the overall value of each product. I considered how much businesses would get for their money, looking at features, scalability, and risk-free guarantees like Norton’s 60-day money-back policy.Testing Methodology: Comparison & Ranking Criteria
  • I evaluated the customer support and service offered by each provider. Businesses need prompt and reliable assistance to resolve security issues. I reviewed the quality and accessibility of each company’s customer support, including 24/7 availability and whether they provided dedicated account managers.

Personal vs. Business Antivirus Solutions: Key Differences

Do you need a dedicated business antivirus suite to protect your business from cyber threats? Or is a personal antivirus you already use to protect your home devices enough? To help you decide, I’ve compiled this list of key differences between personal and enterprise antivirus solutions:

  • Scalability. Personal antivirus solutions are typically designed to protect a single device or a few of them, whereas enterprise antivirus solutions can be deployed across dozens or even hundreds of devices.
  • Customization. Compared to personal antivirus solutions, enterprise antiviruses usually offer more customization options. IT administrators can alter the security settings to cater to the organization’s unique needs more effectively.
  • Management. Personal antivirus solutions are typically managed by the individual user, whereas enterprise antivirus solutions are centrally managed, which allows for greater control over security settings and better coordination of security protocols across the organization.
  • Pricing. Individual antivirus solutions are often free or available through an affordable subscription model, while enterprise antivirus solutions may be pricier owing to their extra features and customization options.
  • Technical support. This is typically better in business-grade antivirus than personal ones. While company IT departments can get dedicated help with deployment, setting up, and troubleshooting, individuals might have to rely on community forums or knowledge bases for support.

Does My Small Business Really Need an Antivirus?

Every business, regardless of size, needs antivirus software. With cyber threats rapidly evolving, small businesses are increasingly becoming targets. Hackers take advantage of the fact that many small business owners believe they don’t have enough valuable information on their servers to be worthwhile targets — whereas, in reality, small businesses often hold sensitive data like customer information, payment details, and more.

An antivirus is the first line of defense against cybercriminals trying to steal this information, protecting your digital assets from malware, ransomware, and other forms of cyber attack. This is also important for small businesses with remote employees, as remote work can bring added security risks if devices aren’t adequately protected.

Additionally, your role as a business owner extends beyond protecting your assets — it involves safeguarding the data of your employees and clients, too. Cyber attacks can result in extensive data breaches that put everyone at risk. A reliable antivirus program is critical to upholding this responsibility, preserving the trust and confidence integral to your business relationships.

Lastly, it’s your legal obligation to comply with data privacy laws such as GDPR or the California Consumer Privacy Act. These laws require businesses to implement reasonable measures to ensure data protection, and non-adherence can lead to severe penalties.

Overall, prevention is indeed the best strategy when it comes to cybersecurity. Don’t let the size of your business determine your level of protection.

Top Brands That Didn’t Make the Cut

  • Avira. Unfortunately, Avira no longer offers a dedicated business product line. While Avira Prime is a great antivirus for home use, and it could technically be used for protecting your business devices as well, there are simply better business-focused offerings on the market.
  • Heimdal. While I think Heimdal offers very advanced cybersecurity protection, it may be too complex for many businesses looking for an easy-to-use antivirus suite. That said, it could be a good option for larger enterprises with dedicated IT teams that can install and manage the software.
  • Webroot. Webroot is lightweight, has good malware scanning, and comes with an excellent password manager, but its ransomware protection is disappointing. Additionally, Webroot’s system optimization tools are very basic.
