How to choose antivirus and EDR protection for your company

How should a company choose secure antivirus protection?

Compare endpoint protection platforms (EPP), endpoint detection and response tools (EDR), and managed detection and response services (MDR). Assess detection, response, central management, reporting and performance impact. Virtline helps match coverage to devices, risk, budget and the team responsible for operation.

• Test protection against ransomware, phishing, malicious macros and suspicious scripts.
• Assess coverage for off-site laptops, servers, mobile devices and privileged accounts.
• Verify who handles alerts and how quickly that person can decide to isolate a device.
• Define acceptance evidence for policies, exceptions, reporting, isolation and post-incident review.

Antivirus is only one part of endpoint protection

Antivirus, EDR, email protection and response processes have distinct roles. In Microsoft environments, test Safe Attachments in Defender for Office 365 separately from Defender for Endpoint alert handling and isolation. Availability depends on licensing, OS, agent version, configuration and permissions; a package name does not prove every control works.

• EPP and antivirus can block malicious files and behaviour; effectiveness depends on the threat, policies, updates and supported platform.
• EDR records endpoint behaviour, supports investigation and can isolate a workstation or server.
• XDR correlates endpoint, email, identity and network signals into one incident path.
• Every alert needs an owner, an SLA, an escalation route and a documented decision.

Which companies particularly need EDR or MDR?

The decision matters most for organisations with sensitive data, distributed teams, Microsoft 365, multiple locations, remotely accessible servers or ISO 27001 and NIS2 obligations. In medium-sized companies, risk often comes from practical exceptions, unmanaged devices and the absence of a team that continuously reviews the console.

• Laptops used away from the office or kept offline and beyond corporate network control.
• Legacy systems, applications requiring exclusions and servers with high business impact.
• No internal SOC or administrators available outside standard business hours.
• Customer, audit, cyber-insurance or regulatory requirements for detection and response.

How should the inventory be prepared before comparing offers?

Vendor comparison becomes meaningful only after the company knows what must be protected. The inventory covers operating systems, locations, user roles, intermittently offline devices, servers, virtual environments, applications that need exclusions and the current agent-deployment method. Without this baseline, offers cover different scopes and neither price nor risk can be compared fairly.

• Count active, inactive and occasionally connected devices by operating system and owner.
• Mark critical servers, privileged devices, VDI, mobile assets and workstations outside the domain.
• Collect current policies, exclusions, alert history, expiring licences and performance problems.
• Map integrations with Active Directory, Microsoft 365, SIEM, MDM, RMM, helpdesk and backup.

Criteria for se­lect­ing a solution for the company

A good solution should have a central console, policies for device groups, reports, station isolation, phishing protection, USB drive control, identity integration and the ability to export alerts to SIEM. The costs of implementation, maintenance and incident handling are also important, not just the annual licence price.

How should the vendor, licence and operating costs be compared?

The technical matrix must include contract terms, support, telemetry retention, data location, administrative roles, APIs, data export and an exit path. A cheap licence can become expensive when operation is manual, servers are excluded or historical evidence becomes unavailable after a vendor change.

• Compare the exact scope of EPP, EDR, XDR, email protection, sandboxing, device control and MDR.
• Check data retention and location, roles, administrator MFA, APIs and alert-export options.
• Verify support SLA, language, escalation rules and the responsibilities of vendor, partner and MDR provider.
• Calculate rollout, migration, tuning, exception maintenance, alert handling, training and exit costs.

Integration with Microsoft 365 and MFA

Endpoint protection should be consistent with email, identity and application access. If a company uses Microsoft 365, it is worth combining workstation policies with MFA, secure email configuration, macro restrictions, link filtering and response to suspicious logins.

How to run a pilot without chaos

Select representative devices and applications, including mobile laptops and servers. Measure performance impact, false alerts and response time. Test exception handling and device isolation. Assign an owner, evaluation criteria and a recorded result to each stage.

• Define scope, critical business processes, device groups and the risks the pilot must confirm.
• Create policies for workstations, servers and privileged users and name the owners of exceptions.
• Measure load, application conflicts, false positives, device visibility and response time.
• After the pilot, prepare rollout waves, user communication, rollback and the alert-handling procedure.
• Before the pilot: define scope, risks, owners, agent compatibility and scenarios; maintain existing protection and urgent-alert handling.
• During the pilot: test policies, exclusions, performance, isolation and escalation; meet acceptance criteria before expanding.
• During rollout: deploy in waves, verify coverage and response, document results and prioritise further changes by risk.

Decision matrix for antivirus, EDR and MDR

Record the decision in a matrix that compares risk, technical scope and the operating model. Some companies need well-managed endpoint security with a central console. Environments with many laptops, remote work, customer data or audit requirements may need EDR with MDR or SOC response. The decision covers not only product features but also the full cost of rollout, alert handling, exception maintenance, reporting and an MDR service where needed. A well-run selection reduces blind spots and lets management address risk using evidence.

• Decide whether the company needs prevention only or also incident investigation and host isolation.
• Confirm who handles alerts after hours and how quickly that person can isolate a device.
• Compare visibility into processes, PowerShell, macros, RDP, USB media, phishing and Microsoft 365 events.
• Determine how the solution supports management, ISO 27001, NIS2, customer and cyber-insurance reporting.
• Risks are prioritised by impact, likelihood and the company’s ability to respond.
• Each control has an owner, deadline, acceptance criterion and operating evidence.
• IT, security, helpdesk and management work from the same decision matrix.
• Compare cost across the complete operating model rather than the annual licence fee alone.

Alert-handling and escalation model

EDR creates value only when the company can distinguish an informational alarm from an incident requiring immediate isolation. The operating model defines severity levels, coverage hours, authority to act, business-owner communication and the evidence needed for closure. With MDR, monitoring, recommendation and autonomous provider action must be separated explicitly.

• Define alert categories and times for acknowledgement, escalation, isolation and business communication.
• Assign roles to helpdesk, administrator, SOC or MDR, system owner and decision maker.
• State which actions may be automated and which need approval before a device is disconnected.
• Record cause, decision, actions, artifacts, impact, closure and lessons from each incident.

Acceptance criteria after endpoint-protection rollout

It is not enough to state that the agent is installed. Evidence must show that workstations and servers report to the console, alerts have owners, exceptions are documented and the ransomware scenario is connected to backup, escalation and communication.

• Coverage report for devices, agent versions, policies and inactive or unprotected computers.
• Register of exceptions, exclusions and business applications with an owner, rationale and review date.
• Alert-response test covering classification, isolation, communication, closure and evidence retention.
• Integration with MFA, email, backup, patch management, SIEM and monitoring of critical services.

Ransomware-scenario test before acceptance

Use agreed safe simulations in a test environment; do not run real ransomware in production. The standard EICAR antivirus test file checks a specific detection path, not ransomware resilience. Separately verify telemetry, isolation permissions, escalation and recovery. Server isolation testing requires a maintenance window and rollback plan.

• Confirm that the alert reaches the correct queue and receives an owner within the required time.
• Test endpoint isolation, remote access, artifact collection and protection of the remaining devices.
• Connect the incident to clean-backup verification, restore order and crisis communication.
• Close the test with timings, decisions, gaps, correction owners and a date for the next exercise.

When the tool itself is not enough

Even excellent software cannot replace updates, backup, MFA, segmentation, training and continuous alert handling. If the company has no internal security team, the solution must be connected to administration, helpdesk or SOC monitoring and to a regular policy-review cycle.

• Provide staffing and escalation appropriate to risk and SLA. Critical alerts need action within the agreed time rather than waiting for a daily console review.
• Connect endpoint security with patch management, MFA, backup, email protection and macro controls.
• Define when a device is isolated, rebuilt or transferred to full incident response.
• Review false positives, inactive devices, exceptions and coverage gaps every month.

ESET as one endpoint-protection option

ESET is one of the solutions companies consider for its central console, protection of workstations, servers and email, device control, reporting and policy deployment. The exact package and licence should follow an analysis of the environment, required response level and operating model rather than a price-list comparison alone.

Which evidence and review rhythm should remain?

The project should leave an agreed scope, decision matrix, configuration and policy exports, named owners, approved exceptions, test results, incident records, a coverage report and scheduled reviews. Monthly or quarterly reviews should track device coverage, agent versions, exception age, alert acknowledgement, isolation time, unowned alerts and the latest ransomware exercise. Management receives trends and budget decisions; administrators receive a prioritised remediation backlog.
