Best Cybersecurity Software for Small Businesses in Europe 2026: Compare Features, Pricing and Protection

Cybersecurity software is no longer optional for small businesses. A single compromised email account, unpatched laptop or stolen password can expose customer data, disrupt operations and create significant recovery costs.

The challenge is that “cybersecurity software” can describe several different products. Some tools protect laptops and servers, while others secure email, identities, cloud applications or remote connections. The best solution therefore depends on your devices, workforce, industry and internal IT resources.

This guide compares leading cybersecurity options for small businesses across Europe in 2026, including endpoint protection, EDR, ransomware defence, managed detection and secure remote access.

Pricing note: Prices and features were checked in July 2026. European pricing can vary by country, currency, VAT status, contract length, number of users and reseller. Always request a written quotation covering the complete contract and renewal price.

No provider is automatically best for every European business. Microsoft may offer better value for companies already using Microsoft 365, while Sophos or ThreatDown may suit organisations seeking managed threat response. NordLayer addresses network access and should normally complement—not replace—endpoint protection.

1. Microsoft Defender for Business

Microsoft Defender for Business is a strong option for companies using Windows devices and Microsoft 365. It supports organisations with up to 300 users and can protect Windows, macOS, Android and iOS devices.

Core features include:

• Next-generation antivirus protection
• Endpoint detection and response
• Threat and vulnerability management
• Automated investigation and remediation
• Attack-surface reduction
• Centralised security administration
• Protection for up to five devices per licensed user

In the UK, Microsoft lists Defender for Business at £2.30 per user per month, paid yearly. A separate server licence is also listed at £2.30 per month.

Microsoft 365 Business Premium costs £16.90 per user per month, paid yearly, and combines Defender for Business with Microsoft Defender for Office 365 Plan 1, Microsoft Intune, Entra ID, Office applications and 1 TB of cloud storage per user.

These are UK prices before any applicable taxes, and prices in eurozone and other European markets may differ. See the current Microsoft security pricing for small and medium businesses.

Best for

Businesses already using Microsoft 365 that want endpoint, identity, email and device-management tools within one ecosystem.

Check before purchasing

Confirm whether you need server protection, advanced email security, mobile-device management or assistance configuring the Microsoft security portal. Buying the licence alone does not automatically configure every security policy.

2. Bitdefender GravityZone Business Security

Bitdefender GravityZone is designed to protect business workstations, laptops and servers through a central management platform. It can be attractive to businesses that operate a mixture of Windows, macOS and Linux systems.

Depending on the selected edition and add-ons, capabilities can include:

• Malware and phishing protection
• Behaviour-based threat detection
• Ransomware protection
• Web-attack prevention
• Application and device control
• Endpoint risk analytics
• Patch management
• Endpoint detection and response
• Email and cloud-workload protection

Bitdefender has several GravityZone packages, so buyers should compare the included features carefully. An entry-level endpoint package may not include the same EDR, patching or security analytics provided by a more advanced edition.

Pricing varies by package, device count, subscription term and country. Check the official Bitdefender small-business security options and request local European pricing where necessary.

Best for

Businesses wanting centrally managed endpoint protection across different operating systems.

Check before purchasing

Ask whether server licences, EDR, ransomware remediation, patch management and cloud-email protection are included or sold separately.

3. ESET PROTECT

ESET is a well-established European cybersecurity provider with options for very small companies and larger managed environments. Its business products can protect computers, mobile devices, servers and cloud applications, depending on the package.

Available capabilities may include:

• Endpoint antivirus and anti-malware
• Ransomware and exploit protection
• Web and email protection
• Device control
• Full-disk encryption
• Cloud-application protection
• Extended detection and response
• Centralised cloud management

ESET can be a practical choice for businesses that want a relatively straightforward endpoint product but may later need encryption, cloud security or XDR capabilities.

Prices depend on the country, package, number of devices and subscription duration. Review the official ESET small-business security page or contact an authorised local partner.

Best for

Small businesses looking for flexible endpoint protection with central administration and multiple package levels.

Check before purchasing

Verify which operating systems are supported and whether encryption, server protection and Microsoft 365 security are part of the quoted package.

4. Sophos Endpoint and Managed Detection and Response

Sophos combines endpoint protection with EDR and managed detection and response services. It may be particularly relevant for companies that want specialist monitoring but do not have their own security operations team.

Depending on the service purchased, Sophos can provide:

• Endpoint malware prevention
• Behavioural ransomware protection
• Exploit mitigation
• Endpoint detection and response
• Threat investigation
• Managed detection and response
• 24-hour security monitoring
• Firewall and email integrations

The distinction between EDR and MDR is important. EDR gives your organisation investigation and response tools. MDR adds a team of security specialists that monitors alerts and may investigate or respond to threats according to the agreed service.

Sophos generally asks prospective customers to submit their details for pricing. Businesses can request a quote through the official Sophos endpoint pricing page.

Best for

Organisations that want advanced endpoint protection or external security specialists to monitor and respond to threats.

Check before purchasing

Ask whether the service operates 24/7, which response actions the provider is authorised to take and whether threat containment is included or merely recommended.

5. ThreatDown

ThreatDown, from Malwarebytes, offers modular business-security packages ranging from endpoint antivirus to EDR and managed detection and response.

Depending on the plan, features may include:

• Next-generation antivirus
• Vulnerability assessment
• Phishing and web protection
• Device control
• Endpoint detection and response
• Ransomware rollback
• Patch management
• Firewall management
• Disk encryption management
• Managed threat hunting and response

Optional services can include DNS filtering, email security, server protection, mobile security and premium support.

Because features differ significantly between its Core, Advanced, Elite and Ultimate options, businesses should compare packages rather than selecting solely on the lowest advertised price. See the current ThreatDown pricing and product configurator.

Best for

Small businesses wanting a modular path from basic endpoint protection to EDR or managed security.

Check before purchasing

Confirm how long ransomware rollback data is retained, whether MDR includes active remediation and how servers and mobile devices are licensed.

6. Avast Business Security

Avast Business Security is aimed at smaller organisations that need manageable protection for employee computers. Package features can include endpoint antivirus, web protection, ransomware defence, VPN access, patch management and privacy tools.

Its relatively accessible packaging may suit a microbusiness that does not need a complex enterprise security platform. However, companies handling sensitive data should compare its detection, reporting, policy-management and incident-response features against dedicated EDR or MDR products.

Prices can vary by country, number of devices, plan and promotional period. Buyers should check the official Avast Business store and review the renewal price—not only the initial discount.

Best for

Microbusinesses wanting packaged security for a limited number of computers.

Check before purchasing

Confirm that the quoted licence permits commercial use and determine whether patch management, VPN, server protection and advanced threat investigation are included.

7. NordLayer

NordLayer focuses on secure business network access rather than acting as a complete endpoint-security suite. It can help companies control how employees connect to business systems from homes, coworking spaces and public networks.

Features vary by plan but may include:

• Business VPN connections
• Dedicated gateways
• Network access controls
• Single sign-on integrations
• Multi-factor authentication support
• DNS and web filtering
• Device posture or compliance checks
• Zero Trust network-access capabilities

NordLayer can be useful for remote and hybrid companies, but it should normally operate alongside endpoint protection, email security, MFA and secure backups.

Pricing is generally based on the selected plan and number of users. Review the latest options on the official NordLayer pricing page.

Best for

Distributed teams requiring centrally managed and restricted access to company systems.

Check before purchasing

Ask about gateway charges, minimum user numbers, supported identity providers, logging, data-processing terms and the locations from which the service is delivered.

What Cybersecurity Protection Does a Small Business Need?

Installing business antivirus is helpful, but it is only one security layer. A practical small-business security programme should normally consider the following controls.

Endpoint protection and EDR

Endpoint protection blocks known malware and suspicious behaviour on computers and servers. EDR provides greater visibility into what happened, which devices were affected and how a threat should be contained.

Businesses without staff capable of investigating EDR alerts may benefit more from an MDR service.

Email and phishing security

Email remains a major entry point for password theft, fraudulent payment requests and malicious attachments. Businesses using Microsoft 365 or Google Workspace should check whether their existing plan provides sufficient email protection.

Identity and access security

Enable multi-factor authentication wherever possible, particularly for email, cloud administration, finance systems and remote access. Administrative access should be restricted and separated from ordinary day-to-day accounts.

Patch and vulnerability management

Attackers frequently exploit outdated software. A suitable solution should help identify missing updates and vulnerable applications across all managed devices.

Secure remote access

Remote employees should not receive unrestricted access to the entire company network. Consider business VPN or Zero Trust access products that limit each user to the systems required for their role.

Backups and recovery

Endpoint protection does not replace backups. Maintain encrypted backups separately from the production environment and test whether files and systems can actually be restored.

ENISA’s guidance for SMEs recommends centralised antivirus, MFA, software updates, email and web protection, secure remote access, incident planning and separated, tested backups. The full recommendations are available in the ENISA Cybersecurity Guide for SMEs.

How Much Does Small-Business Cybersecurity Software Cost?

The headline licence price rarely represents the complete cost. A business may have to pay separately for:

• Employee and contractor accounts
• Workstations and mobile devices
• Windows or Linux servers
• Email-security licences
• EDR or XDR capabilities
• MDR monitoring
• Patch management
• Backup storage
• Implementation and migration
• Staff security training
• Premium support
• VAT and local taxes

Some vendors charge per user, while others charge per device. A per-user licence can be attractive when each employee operates several devices, but only if all those devices are included.

Request quotations based on the same number of users, computers, mobile devices and servers. Compare the total first-year cost, renewal cost and cost of optional services.

Cybersecurity Software and European Compliance

No cybersecurity product makes a company automatically compliant with GDPR or any other European law. Compliance also involves policies, contracts, access controls, staff training, documented risk decisions and incident-response procedures.

Under GDPR, an organisation may need to notify the relevant supervisory authority of a personal-data breach within 72 hours of becoming aware of it when the breach is likely to pose a risk to individuals. Higher-risk breaches may also require notification to affected individuals. The European Commission explains these obligations in its official personal-data breach guidance.

NIS2 does not apply automatically to every small company. As a general rule, it covers medium-sized and large entities in specified critical sectors, although certain smaller entities may be included because of their importance or under national implementation rules. The European Commission provides an overview of the NIS2 Directive and its scope.

Businesses operating across several European countries should obtain advice based on their sector, company size, locations and national laws.

Questions to Ask Cybersecurity Vendors

Before signing a contract, ask each provider:

1. Is pricing calculated per user, device, server or company?
2. Is there a minimum licence quantity?
3. Which Windows, macOS, Linux, Android and iOS versions are supported?
4. Are servers and cloud workloads included?
5. Does the product provide antivirus only, or full EDR?
6. Who investigates security alerts?
7. Does MDR operate continuously, including weekends?
8. Can the provider isolate a compromised device?
9. Are ransomware rollback and data recovery included?
10. Does the package include email and phishing protection?
11. Can it manage operating-system and third-party software updates?
12. What logs are stored, and for how long?
13. Where is customer data processed?
14. Is a GDPR data-processing agreement available?
15. What support response times are guaranteed?
16. What will the subscription cost after the introductory period?
17. How can company data and reports be exported when the contract ends?

How to Choose the Best Cybersecurity Software

Start by creating an inventory of employees, devices, servers, applications and sensitive data. Then identify the most realistic risks.

A five-person consultancy using Microsoft 365 may prioritise account security, laptop protection and secure backups. An online retailer may also need payment-security controls, website monitoring and 24-hour incident support. A manufacturer could require protection for operational systems and may face additional NIS2 considerations.

Shortlist products that support your actual environment and run a controlled trial. During the trial, assess:

• Installation and device performance
• Accuracy and usefulness of alerts
• Central management
• Reporting quality
• Support availability
• Ease of adding and removing employees
• Integration with existing email and identity systems
• Incident containment and recovery procedures

Avoid installing multiple real-time endpoint antivirus products on the same device unless the vendors explicitly support that configuration.

Frequently Asked Questions

Is antivirus enough for a small business?

Usually not. Antivirus should be combined with MFA, email security, software updates, restricted administrative access, backups and staff training. Companies facing greater risk may also need EDR or MDR.

What is the difference between EDR and MDR?

EDR is software that records endpoint activity and provides investigation and response tools. MDR is a managed service in which security specialists monitor and investigate threats. The exact response actions depend on the contract.

Is Microsoft Defender included with Windows?

Windows includes built-in Microsoft Defender Antivirus, but Microsoft Defender for Business adds centralised business management, EDR, vulnerability management and other organisational security features.

Can a business use free antivirus software?

Some free products prohibit commercial use or lack central management, reporting and business support. Review the licensing terms before installing a consumer or free product on company devices.

Do Macs need business endpoint protection?

Macs can still face malicious software, stolen credentials, unsafe applications and browser-based attacks. A company should apply consistent security and monitoring policies across every supported operating system.

Does endpoint security protect Microsoft 365 email?

Not necessarily. Endpoint security and cloud-email protection are separate capabilities in many packages. Check whether phishing, malicious attachments, suspicious links and account compromise are covered.

Does cybersecurity software replace backups?

No. Security products reduce risk but cannot guarantee that every attack will be stopped. Maintain separate, encrypted and regularly tested backups.

Which cybersecurity software is best for a remote team?

A remote team usually needs endpoint protection, MFA, secure identity management, email security and restricted remote access. A network-security product such as NordLayer may complement an endpoint platform such as Microsoft Defender, Bitdefender, ESET or Sophos.

Final Verdict

The best option depends on the organisation:

• Best for Microsoft 365 users: Microsoft Defender for Business or Microsoft 365 Business Premium.
• Best for flexible endpoint management: Bitdefender GravityZone or ESET PROTECT.
• Best for advanced or managed threat response: Sophos Endpoint with MDR or a suitable ThreatDown MDR package.
• Best for a small number of basic business devices: Avast Business Security.
• Best for secure remote network access: NordLayer, combined with endpoint and identity protection.

Compare the complete protection package—not merely the antivirus price. The most effective solution is one that covers every business device, is correctly configured, produces actionable alerts and is supported by tested backup and incident-response procedures.
