Cybersecurity is no longer something only large corporations need to worry about. Small businesses are increasingly dependent on computers, cloud applications, email, websites, online payments, and remote workers, making reliable cybersecurity software an important part of everyday business operations.
The best cybersecurity software for small business should do more than detect traditional viruses. A strong solution can help protect company computers, employee devices, business data, email accounts, and customer information from threats such as ransomware, phishing, malware, credential theft, and unauthorized access.
For small businesses with limited IT resources, ease of management is also important. A complicated security platform that nobody monitors consistently may provide less practical protection than a solution that employees and administrators can actually manage properly.
What Should Small Businesses Look for in Cybersecurity Software?
Before choosing a security platform, consider the specific risks your company faces.
Important capabilities can include:
-
Malware and ransomware protection
-
Phishing and malicious website protection
-
Endpoint security
-
Firewall and network protection
-
Vulnerability management
-
Automatic security updates
-
Email security
-
Device management
-
Multi-factor authentication
-
Data backup and recovery
-
Security monitoring and alerts
-
Centralized administration
-
Mobile-device protection
No single security product necessarily provides every security control a business needs. Cybersecurity works best as a layered approach that combines software, employee awareness, access controls, backups, and good security practices.
Microsoft Defender for Business
Microsoft Defender for Business is designed specifically for small and medium-sized organizations with up to 300 users. Microsoft says it provides protection against ransomware, malware, phishing and other threats across supported devices.
One advantage is its integration with the Microsoft ecosystem. Businesses already using Microsoft 365 may find it easier to manage security alongside their existing productivity tools.
Defender for Business includes capabilities such as next-generation antivirus, endpoint detection and response, vulnerability management, attack-surface reduction, automated investigation and remediation, and centralized management.
Microsoft currently lists Defender for Business at $3 per user per month when paid annually, before applicable taxes, although pricing and availability can vary by market and subscription arrangement.
Microsoft also offers Microsoft 365 Business Premium, which includes Defender for Business together with additional security and productivity capabilities.
Bitdefender GravityZone
Bitdefender GravityZone is another business-focused cybersecurity platform worth considering.
Bitdefender offers packages specifically designed for small businesses, including GravityZone Small Business Security and GravityZone Business Security. Its platform provides centralized management and protection against threats such as ransomware, phishing, malware and web-based attacks.
GravityZone Business Security includes endpoint protection, network attack defense and risk management. Bitdefender also provides features such as behavioral analysis, machine-learning technologies, web filtering and centralized security management.
This type of centralized management can be particularly useful for a company with multiple laptops and desktop computers because administrators can manage security policies from one location.
Bitdefender also offers different packages, allowing businesses to select security capabilities according to their size and requirements.
Sophos Endpoint
Sophos Endpoint is another business cybersecurity option, particularly for organizations looking for endpoint protection with centralized management.
Sophos says its endpoint platform is designed to protect small businesses as well as larger organizations. The company highlights features including exploit mitigation, malware prevention, ransomware protection, web and application controls, and additional security capabilities.
Sophos also offers managed detection and response services for businesses that want security professionals to provide additional monitoring and oversight.
For a small business without a dedicated cybersecurity team, this type of managed service can be worth investigating because maintaining security software is only one part of managing cyber risk.
Cybersecurity Software vs. Antivirus
One important distinction is the difference between traditional antivirus software and modern endpoint security.
Traditional antivirus primarily focuses on detecting malicious files and programs.
Modern endpoint protection can go further by monitoring suspicious behavior, identifying vulnerabilities, controlling applications, detecting attacks, and helping security teams investigate incidents.
For example, Microsoft describes Defender for Business as extending beyond traditional antivirus with endpoint detection and response, vulnerability management, attack-surface reduction, and automated investigation and response.
For businesses handling sensitive customer or financial information, these additional capabilities may be important.
Don’t Forget Email Security
Email remains an important security consideration for small businesses because employees can receive phishing messages containing malicious links, attachments, or fraudulent requests.
A cybersecurity strategy should therefore consider protection for business email in addition to computers.
Microsoft 365 Business Premium, for example, includes Defender for Business as well as Microsoft Defender for Office 365 P1 for email protection.
Email security should also be supported by employee training. Employees should know how to recognize suspicious messages, verify unusual payment requests, and avoid entering passwords into unfamiliar websites.
Protect Your Business From Ransomware
Ransomware can prevent employees from accessing files and potentially disrupt business operations.
Security software can help prevent ransomware, but businesses should also maintain reliable backups.
A strong backup strategy should include regularly scheduled backups and a recovery process that has actually been tested.
Don’t assume that having a backup automatically means your business can recover quickly. Test whether files can be restored and determine who is responsible for recovery during an incident.
Keep Software Updated
Cybersecurity software cannot compensate for every outdated application or operating system.
Software updates frequently include security fixes, so businesses should establish a process for keeping operating systems, browsers, plugins, applications and other important software current.
Some business security platforms also provide vulnerability or patch-management capabilities. Microsoft Defender for Business includes vulnerability management, while Bitdefender offers patch-management capabilities in its broader GravityZone packages.
Use Multi-Factor Authentication
A strong password alone may not be enough to protect important business accounts.
Multi-factor authentication adds another verification step when users sign in. This can help reduce the risk associated with stolen or compromised passwords.
Businesses should prioritize MFA for email, cloud storage, financial accounts, administrative accounts and other systems containing sensitive information.
Consider the Number of Devices
The size of your business should influence your cybersecurity purchase.
A company with five employees and ten devices may not need the same security infrastructure as an organization with 200 employees and hundreds of endpoints.
Before purchasing software, determine:
-
Number of employees
-
Number of computers
-
Number of mobile devices
-
Number of servers
-
Operating systems in use
-
Remote workers
-
Cloud applications
-
Business email provider
-
Sensitive information being stored
For example, Microsoft Defender for Business supports organizations with up to 300 users and up to five client devices per user license. Servers require additional licensing.
Compare Total Cost, Not Just Subscription Price
The cheapest cybersecurity product isn’t necessarily the least expensive solution.
Consider the total cost of:
-
Software licenses
-
Additional security modules
-
Server protection
-
Email protection
-
Setup
-
Technical support
-
Managed security services
-
Employee training
-
Administration time
A platform that costs slightly more but is easier to manage could potentially reduce the amount of time your business spends dealing with security issues.
Should You Use Managed Cybersecurity?
Small businesses without an internal IT or security specialist may want to consider a managed security provider.
A managed service can provide additional monitoring, alert handling, configuration and incident-response assistance.
This doesn’t eliminate the need for good internal security practices, but it can give a small business access to expertise that may otherwise be expensive to maintain internally.
How to Choose the Right Cybersecurity Software
Before making a purchase, create a simple comparison:
| Feature | Solution A | Solution B | Solution C |
|---|---|---|---|
| Endpoint protection | ✓ | ✓ | ✓ |
| Ransomware protection | ✓ | ✓ | ✓ |
| Phishing protection | ✓ | ✓ | ✓ |
| Vulnerability management | ✓ | ✓ | ✓ |
| Centralized management | ✓ | ✓ | ✓ |
| Mobile protection | ✓ | ✓ | ✓ |
| Server protection | Check | Check | Check |
| Email security | Check | Check | Check |
| Managed monitoring | Optional | Optional | Optional |
| Price | $ | $ | $ |
The exact capabilities depend on the subscription or package you purchase, so verify the current product documentation before making a decision.
Final Thoughts
The best cybersecurity software for a small business depends on the company’s size, technology environment, budget, security requirements and available IT expertise.
Microsoft Defender for Business, Bitdefender GravityZone and Sophos Endpoint are examples of business-focused security platforms with features designed for small and medium-sized organizations.
However, cybersecurity software should be only one part of your overall security strategy. Use strong passwords, enable multi-factor authentication, keep software updated, train employees to recognize phishing, restrict unnecessary access, and maintain tested backups.
For a small business, the most practical security solution is one that provides appropriate protection and can be consistently managed and maintained as the company grows.
