How We Selected These Cybersecurity Platforms
The order represents an editorial comparison rather than a mathematical ranking. Products were assessed for SMB suitability, endpoint protection, malware and ransomware controls, EDR availability, centralised administration, supported operating systems, scalability, pricing clarity and the amount of security expertise likely to be required.
Official product and pricing documentation was prioritised. Independent testing was used only where the tested product closely matched the product being discussed. For example, AV-Comparatives’ 2026 business testing included Bitdefender GravityZone Business Security Premium and ESET PROTECT Entry, while tests involving other vendors sometimes used different enterprise editions. Such results therefore supplement rather than determine this ranking.
1. Microsoft Defender for Business — Best for Microsoft-Centric SMBs
Microsoft Defender for Business is designed specifically for organisations with up to 300 users. The standalone plan costs $3 per user per month when paid annually and permits up to five client devices per licensed user. It supports Windows, macOS, Android and iOS/iPadOS and includes vulnerability management, next-generation antivirus, endpoint detection and response, automated investigation and remediation, and simplified onboarding.
Its strongest case is for companies already working within Microsoft’s ecosystem. Defender for Business is also included with Microsoft 365 Business Premium.
Buyers should know: email-specific protection through Microsoft Defender for Office 365 is part of broader Microsoft 365 offerings rather than the standalone endpoint subscription, and servers require separate licensing.
2. Bitdefender GravityZone Business Security Premium — Best for Layered Endpoint Protection
Bitdefender GravityZone Business Security Premium combines endpoint protection with capabilities including network attack defence, endpoint risk analytics, machine-learning-based HyperDetect technology, cloud sandbox analysis and protection against fileless attacks. Direct online licensing is available for deployments of up to 100 devices, with larger requirements handled through partners.
It is particularly suitable for growing businesses wanting more security controls than conventional business antivirus while retaining centralised cloud management.
Bitdefender GravityZone Business Security Premium was also among the products independently evaluated in AV-Comparatives’ H1 2026 Business Security Test.
Buyers should know: Business Security Premium should not be confused with Bitdefender’s higher EDR/XDR offerings. Full EDR and wider detection-and-response capabilities require other GravityZone products or services.
3. ESET PROTECT Entry — Best for Mixed-OS Businesses
ESET PROTECT Entry combines its cloud or on-premises management console with endpoint and server security. ESET documents support for Windows, macOS and Linux computers, together with Android and iOS/iPadOS capabilities where applicable.
Its centralised management and broad operating-system coverage make it a practical option for small businesses with mixed device estates rather than Windows-only environments. US business plans can be purchased online for SMB deployments, while larger configurations can be arranged through sales.
ESET PROTECT Entry was directly included in AV-Comparatives’ H1 2026 business evaluation.
Buyers should know: Entry is the base PROTECT tier. Features such as full-disk encryption and advanced threat defence are associated with higher tiers, while EDR-capable ESET options have additional licensing requirements.
4. Sophos Endpoint — Best for Ransomware-Focused Protection
Sophos Endpoint combines malware prevention, exploit mitigation, behavioural detection and its CryptoGuard anti-ransomware technology. CryptoGuard monitors for malicious encryption activity and can automatically roll affected files back after ransomware behaviour is detected. Protection is administered through Sophos Central.
Sophos is particularly worth investigating for organisations concerned about both local and remote ransomware attacks or businesses that may later require more sophisticated security operations.
The product family provides upgrade paths to Sophos EDR, XDR and MDR, with MDR providing 24/7 managed monitoring for organisations lacking an internal security team.
Buyers should know: Sophos does not publish a fixed SMB endpoint price on its US site; pricing is provided as a customised per-user quote. Server and some advanced capabilities require separate products or subscriptions.
5. CrowdStrike Falcon Go — Best for Straightforward Next-Generation Antivirus
CrowdStrike Falcon Go brings the company’s cloud-based Falcon technology to small businesses through a deliberately simplified package. It includes next-generation antivirus, device control, mobile protection and Express Support.
Current US pricing is $7.99 per device when billed monthly or $59.99 per device when billed annually, and direct Falcon Go purchases are limited to 100 devices.
Falcon Go is therefore attractive to small teams wanting a recognised business security platform without immediately adopting a full enterprise detection-and-response stack.
Buyers should know: CrowdStrike’s pricing comparison makes an important distinction between tiers. Falcon Go does not include the EDR and threat-hunting capabilities provided in higher Falcon packages, so businesses specifically searching for EDR should compare Falcon Enterprise or other suitable configurations instead.
6. Norton Small Business — Best for Microbusinesses Without Dedicated IT
Norton Small Business focuses on organisations that need straightforward protection rather than a security-operations platform. The current US offering covers two devices per employee and combines device security with a password manager, secure browser, software updating and 250GB of Windows cloud backup. Premium plans add features including VPN and greater backup capacity.
It deserves consideration for very small businesses where the person managing cybersecurity may also be the owner or office manager. Norton specifically positions the product as manageable without specialised IT knowledge.
Norton Small Business was directly evaluated by AV-TEST in its June 2026 Windows business-security testing and achieved the laboratory’s maximum scores across protection, performance and usability in that test.
Buyers should know: it lacks the advanced EDR, threat hunting and security-operations capabilities available from more sophisticated platforms.
How to Choose the Right Cybersecurity Software for Your Small Business
Endpoint Coverage
Count laptops, desktops, servers and mobile devices before comparing licences. A per-user licence covering several devices can produce a very different cost from per-endpoint pricing.
Security Capabilities
Basic antivirus is only one layer. Depending on the organisation, useful features may include behavioural detection, ransomware protection, web filtering, vulnerability management, device control and EDR.
Management
A centralised cloud console is particularly valuable when employees work remotely or several devices must be administered consistently.
Ease of Use
Businesses without security specialists should consider how much configuration, investigation and ongoing alert management a product requires. Managed detection and response may be worth investigating when internal expertise is limited.
Scalability and Cost
Compare renewal costs, device limits, server licensing, required add-ons and higher-tier features—not simply introductory prices.
Cybersecurity software should also form part of a broader strategy. CISA recommends measures including MFA, strong passwords, software updates, employee phishing awareness and backups alongside security technology.
Frequently Asked Questions
What is the best cybersecurity software for a small business?
There is no single best option for every company. Microsoft Defender for Business is a strong choice for Microsoft-centric SMBs, while Bitdefender, ESET and Sophos may better fit businesses prioritising different endpoint-management or protection capabilities. Device count, operating systems, security expertise and required features should determine the shortlist.
Does a small business need cybersecurity software?
Most businesses depend on endpoints, online accounts and digital information that require protection. Appropriate business security software can help detect or block malware, ransomware and other threats, but it should be combined with MFA, patching, backups, access controls and staff awareness rather than used alone.
Is antivirus enough for a small business?
Basic antivirus can provide an important security layer but may not meet every organisation’s needs. Businesses with sensitive information, remote workers or higher-risk systems may also benefit from vulnerability management, behavioural detection, ransomware controls, device management, EDR or managed security services.
How much does cybersecurity software cost for a small business?
Pricing varies considerably. Some products charge per user, others per endpoint, while products such as Sophos use customised quotes. Businesses should calculate the full annual cost using their real number of users, endpoints and servers and check renewal pricing, optional security modules and minimum licence requirements.
Final Thoughts
There is no universally best small-business cybersecurity platform. Microsoft Defender for Business is particularly compelling for Microsoft-oriented companies, while Bitdefender and ESET provide strong centrally managed endpoint options. Sophos deserves attention where ransomware defences and an MDR upgrade path matter, CrowdStrike Falcon Go suits smaller deployments wanting simpler protection, and Norton Small Business can be practical for microbusinesses without dedicated IT staff.
Before subscribing, compare actual device numbers, operating systems, security requirements, administrative capabilities, available expertise, support and long-term pricing. A product that fits the organisation’s operating model is generally more useful than one chosen from specifications alone.
