Why Free Antivirus Software Won’t Cut it for Your Business

Why is TechnologyAdvice Free?

In 2020, the number of new types of malware increased by approximately 74 percent. Because of all the cybersecurity threats on the web, many companies offer antivirus software free for personal users. And while some businesses want to use this free antivirus software as well, the truth is that free security software generally won’t cut it for your business.

Why free antivirus software doesn’t work for businesses

While free antivirus software can be tempting as a business looking to save money, it can actually cost you more in the long run than just paying for protection in the first place. Here are a few reasons to steer clear.

It’s typically out-dated

Most of the time, companies that offer free antivirus software don’t dedicate the same level of resources to updating and improving it as they do to their paid software. This is understandable since they’re not making any money off of it, and they typically offer it for personal use, which doesn’t have the same threat level. Free antivirus software is generally running on older intel than its paid counterparts, and businesses that use it run the risk of vulnerabilities that paid software versions have addressed.

Instead of antivirus software on its own, you may want to look into an endpoint protection platform (EPP) that includes antivirus, endpoint detection and response (EDR), and threat intelligence. This combination will block malware that attempts to access your network, identify and quarantine threats that are already on your devices, and continuously update as new threats emerge. Threat intelligence is critical for stopping known malware, while EDR can keep zero-day threats from perpetuating a successful attack.

Businesses carry higher-value data

Free antivirus software works for home use because personal accounts carry less valuable data than businesses do. For example, an attacker hacking a home account may get four sets of credentials or credit card numbers if they’re lucky. But the same bad actor going after a business could easily get hundreds or even thousands of personal records. Businesses carry a large amount of valuable data and are vulnerable to a larger array of threats, including ransomware, data scraping, and credential theft.

These businesses need to protect not only their own network but also their clients’ data. While you can’t enforce security measures on your clients’ devices, you can ensure that your site includes an SSL certificate to protect customers’ payment information. Additionally, consider implementing multi-factor authentication (MFA) to verify your customers’ identities and keep their accounts in their hands.

It likely won’t meet compliance regulations

Companies that accept credit or debit card payments directly on their website have to comply with the Payment Card Industry Data Security Standard (PCI DSS). One of the requirements is that your antivirus software is updated regularly, which, as we’ve already covered, may not be the case with a free version.

While the Health Insurance Portability and Accountability Act (HIPAA) isn’t super specific about security requirements because medical organizations vary widely, free antivirus software leaves them vulnerable to attacks that could likely be avoided with paid software. Because there’s an alternative that would protect patient data, free antivirus software would likely not comply with HIPAA regulations.

Businesses in highly-regulated industries, like healthcare or finance, should consider a zero-trust security system that includes or integrates with antivirus software. Zero-trust software constantly verifies a user’s credentials and monitors their activity to ensure they are who they say they are and that they aren’t doing anything out of the ordinary. It flags anomalies up to the IT team, so they can investigate, and it can quarantine potential threats until IT looks into them. For example, if an employee accesses sensitive information late at night, the system may block access until IT has a chance to review the activity and reinstate the credentials.

It may not be licensed for business use

Not only is free antivirus software not ideal for business use, some vendors actually don’t license their free version for businesses. Malwarebytes, for example, only offers its free version for personal use. If you’re caught violating the license agreement, the company will likely revoke your access and you may be required to pay them damages. It’s better to just pay for the software upfront.

Antivirus software is a bit of a base-level security measure, and most businesses are going to need more functionality than just blocking malware. Extended detection and response (XDR) platforms combine several security solutions into a single platform to improve detection and give more context surrounding attacks. XDR provides visibility across all of an organization’s endpoints and automatically monitors, detects, and initiates remediation for threats.
