Endpoint visibility, controlled response and accountable operations
EDR and XDR Endpoint Security Services
We plan and deploy endpoint detection and response around device coverage, compatible policy, useful telemetry, tested containment actions and a named incident workflow.
Request an Endpoint Security ReviewThe operational purpose
Endpoint telemetry creates value only when coverage and response are owned
EDR records security-relevant behaviour on laptops, desktops and servers, then turns suspicious activity into evidence that an analyst can investigate. XDR can correlate endpoint signals with identity, email, cloud and network context where supported. Neither term guarantees protection on its own: agent health, policy scope, alert ownership, response authority and regular testing determine whether the platform can help during a real incident.
Assessment and deployment scope
The endpoint estate is mapped before a broad agent rollout
Device and operating-system inventory
Supported laptops, desktops, servers, virtual machines, remote devices and special workloads are recorded with owners and business importance.
Compatibility and pilot groups
Operating systems, existing security software, line-of-business applications, performance constraints and deployment methods are tested on representative devices.
Policy and exclusion review
Prevention, detection, tamper protection, scanning, network controls and justified exclusions are documented instead of copied into one global policy.
Telemetry and integrations
Endpoint events, identity, email, firewall, SIEM, ticketing and notification paths are connected only where they add investigation or response value.
Containment authority
Device isolation, file quarantine, process termination, evidence collection and approval boundaries are agreed before an urgent event occurs.
Coverage and platform health
Inactive agents, stale devices, sensor faults, missing updates and onboarding gaps are measured so blind spots remain visible.
EDR and XDR
EDR investigates endpoint behaviour; XDR can connect the wider attack story
EDR focuses on activity observed on protected endpoints: processes, files, accounts, network connections and other security telemetry. It supports alert investigation and response actions such as isolating a device or quarantining a file when the licensed platform and policy allow them.
XDR extends the investigation by correlating supported signals across more than one security domain. The practical boundary depends on the selected product, licences, connected services and retained data. We document the available data sources and test the actual response path rather than presenting XDR as an automatic replacement for analysts, SIEM or incident procedures.
Controlled rollout
Six stages from readiness review to an accepted response workflow
-
01
Inventory and risk priorities
Devices, users, operating systems, critical applications, existing controls, remote-work patterns and likely incident impact are recorded.
-
02
Architecture and licensing review
Required capabilities, management tenant, roles, retention, integrations, licence boundaries and data-location considerations are checked.
-
03
Pilot deployment
Representative endpoints are onboarded first; agent health, application compatibility, performance and security events are observed.
-
04
Policy and exclusion tuning
Prevention settings, detections, exclusions and response permissions are adjusted from documented evidence and approved risk decisions.
-
05
Incident simulation and handover
Safe test events verify alert delivery, evidence, device identification, containment approval, escalation and communication.
-
06
Coverage and operations review
Unhealthy agents, unresolved incidents, policy drift, exclusions, platform changes and service reports are reviewed on an agreed schedule.
Incident handling
Containment decisions balance security urgency with business impact
An alert is first validated against the affected device, user, process tree, file, network activity and related signals. Severity alone is not enough. A false positive, a controlled administrative tool and active malicious behaviour can look similar without context.
When containment is justified, the runbook identifies who may isolate the device, which business owner must be informed, how evidence is preserved and how the device returns to service. The final record includes the alert classification, affected assets, actions, open risks and any policy or monitoring change required.
Operational handover
What an endpoint security handover should contain
Endpoint coverage register
Protected, pending, unsupported and retired devices with platform health and responsible owners.
Policy and exception record
Applied policies, exclusions, business justification, approver and review date.
Role and access matrix
Administrative, analyst, approval and reporting permissions with account protection requirements.
Alert and escalation matrix
Severity, notification route, owner, expected action, coverage hours and escalation contacts.
Incident response runbook
Triage, evidence, containment, communication, recovery and closure steps for common endpoint events.
Acceptance evidence
Pilot results, test alerts, agent health, response-action checks, known limitations and open work.
Useful planning input
What to send for an EDR or XDR scope review
- Endpoint estate
- Device counts, operating systems, locations, remote users, server roles and business-critical applications.
- Current security stack
- Antivirus or EDR product, licences, management tenant, firewall, email security, identity, SIEM and ticketing tools.
- Operational expectations
- Coverage hours, internal security roles, desired alerts, response authority, reporting and compliance requirements.
- Known constraints
- Legacy systems, application exclusions, limited bandwidth, maintenance windows, data-location rules and recent incidents.
Frequently asked questions
EDR and XDR Endpoint Security Services FAQ
What is the practical difference between antivirus and EDR?
Traditional antivirus primarily prevents and removes known malicious software. EDR adds behavioural telemetry, investigation context and response actions for suspicious endpoint activity. Product capabilities vary, so required prevention and response functions are checked against the selected licence.
What is the difference between EDR and XDR?
EDR concentrates on endpoints. XDR can correlate supported data from endpoints with other domains such as identity, email, cloud applications and networks. The result depends on which services are connected and what data the organisation is licensed and configured to collect.
Does installing an EDR agent complete the project?
No. Coverage, policy compatibility, exclusions, roles, alert ownership, containment permissions, integrations, health monitoring and incident testing are all needed for an operable deployment.
Can EDR isolate an infected computer?
Many EDR products offer device isolation, but the available action depends on the product, licence, operating system and policy. Biga Bilisim defines who may approve or perform isolation and tests the effect on management and business services.
Does Biga Bilisim monitor every EDR alert 24/7?
Only when continuous monitoring is included in a separately defined service. Deployment, platform management, scheduled review and 24/7 security operations have different coverage, escalation and response responsibilities.
Can EDR and XDR services be delivered across Turkey?
Yes. Readiness assessment, tenant configuration, agent rollout, policy, integrations, reporting and remote support can be delivered across Turkey when secure access is available. On-site work is planned when devices or network conditions require physical verification.
