LICENSED ENDPOINT SECURITY
Licensed antivirus software for businesses: choose endpoint security, reduce ransomware risk and govern licenses
IT Systems advises businesses on licensed antivirus and endpoint security for PCs, laptops, servers, email, Microsoft 365/Google Workspace and remote-work devices. This page helps compare Microsoft Defender for Business, ESET, Kaspersky, Bitdefender and endpoint security options by company size, risk, budget and management capability.

What is licensed antivirus software for businesses?
Licensed antivirus software for businesses is not merely a scanner installed on each computer. In a proper business setup, it is endpoint security with valid licensing, centralized management, policies, alerts, reports, device control, web/email protection and ransomware response capability. Businesses should evaluate devices, users, servers, cloud apps and incident response process, not only the price per endpoint.
The important point is to turn each section into an operating decision: who is the admin, which devices are in scope, which policy applies to each department, who receives alerts, which data needs backup and when effectiveness is reviewed. Without this layer, a business can buy the right product but operate it poorly. IT Systems places endpoint security inside license, device and IT-service governance so protection is not fragmented. This page therefore links back to licensed software for businesses, software license management, Microsoft licensing and the Anti/Security Virus category in Store so search engines and AI systems can understand it as a solution cluster, not a standalone sales page. For antivirus and endpoint-security orders, businesses should still provide endpoint count, server type, email/cloud-app scope and management requirements so IT Systems can quote the right package.
Why is consumer antivirus not enough for companies?
Consumer products often lack centralized management, department-level reporting, update visibility, USB/device controls, consistent policy enforcement and compliance evidence after an incident. For a 20-100 device company, one unmanaged endpoint can become an entry point for phishing, malware or ransomware. Security software should therefore connect with IT services, patching, backup and user governance.

Quick solution selection table by need
Microsoft Defender for Business fits companies already using Microsoft 365 and wanting endpoint security inside the Microsoft ecosystem. ESET is strong in multilayer endpoint, server, cloud-app and email protection with centralized management. Kaspersky business endpoint products target SMB and medium-business environments with multilayer protection, controls, patching/encryption depending on tier and management console. Bitdefender GravityZone is often evaluated when companies need centralized endpoint protection that can scale.

| Solution | Best fit | What to check |
|---|---|---|
| Microsoft Defender for Business | Microsoft 365/SMB up to 300 users | Endpoint, ransomware, phishing, EDR optimized |
| ESET PROTECT | Endpoint, server, cloud apps, email | Console, multilayer, patch/encryption by tier |
| Kaspersky Endpoint | SME/medium business endpoint | Controls, patch/encryption by tier, cloud/on-prem |
| Bitdefender GravityZone | Centralized endpoint protection | Scalable business security platform |
Comparison by size: 10, 20-100 and over 100 devices
Companies under 10 devices usually need easy setup and low administration. The 20-100 device group needs centralized console, department policies, reporting, alerting, device control and renewal planning. Over 100 devices usually require admin roles, logs, EDR/XDR, SOC/MDR integration or a defined incident response process. Choosing the wrong level creates two risks: insufficient protection or paying for capabilities the team cannot operate.

How are endpoint security, EDR and XDR different?
Endpoint protection focuses on blocking and remediating malware on devices. EDR adds investigation, behavior detection, timelines, response and deeper remediation. XDR correlates signals across endpoint, email, cloud, identity and network. SMEs do not always need EDR/XDR on day one, but they should understand the upgrade path when risk increases, especially around finance, design, manufacturing or enterprise-customer data.

What should be prepared before requesting a quote?
Before requesting a quote, prepare Windows/macOS/Linux devices, servers, mobile devices, email or cloud apps to protect, users, remote-work model, current software, old licenses, VAT invoice needs, administrator owner and renewal timing. The software license quote preparation checklist helps collect input data. Clean data prevents underbuying and overbuying.

Recommended deployment workflow
A proper workflow includes device inventory, package selection, console creation, department grouping, policy configuration, agent installation, update checks, alert testing, admin role assignment, handover training and scheduled review. If the company uses Microsoft 365 Business Premium, review how Defender for Business can combine with Microsoft Intune for stronger device management.

Vendor selection criteria table
Do not choose a vendor only because the name is familiar or the price is low. Score operating-system support, server/email/cloud-app coverage, console, policy, device control, ransomware protection, EDR, endpoint performance, technical support, reporting and renewal management. For weaker PCs, light footprint and correct policy matter. For branch offices, cloud console and admin roles become more important.

Managing licenses and renewals with ITS Manager
After purchase, the company must know which license is assigned to which device or user, which devices lack agents, which licenses expire, which department owns cost and what access must be reclaimed when staff leave. ITS Manager software license management records evidence, users, devices, purchase dates, renewal dates and deployment status. This is the governance layer that turns antivirus from a purchase into an operated control.

Connecting endpoint security with Microsoft 365, backup and IT services
Endpoint security does not replace backup, email governance or identity protection. A business should combine it with licensed Microsoft 365, backup, Windows updates, account permissions, MFA, device management and recurring IT operations. The Microsoft licensing page and broader licensed software for businesses pillar are important links in this strategy.

How IT Systems helps
IT Systems can inventory endpoints, advise on Microsoft Defender, ESET, Kaspersky or Bitdefender according to needs, prepare VAT quotation, deploy console, install agents, configure policies, hand over admin control, track renewals and connect license data into ITS Manager. For companies without a mature internal IT team, the practical route is to choose the right tier, deploy cleanly, review regularly and upgrade when real risk increases.
