GravityZone XDR is Bitdefender's Extended Detection and Response platform. Alongside the data collected by the endpoint EDR sensor it adds telemetry from network, identity, productivity applications and cloud sensors, and presents these sources not as separate alert lists but as a single attack chain. The goal is not to increase the number of alerts but to reduce signals that appear unrelated into one incident.
The measurable counterpart of this approach is alert volume. According to Bitdefender's own announcement, 19 vendors were tested in the 2024 MITRE Engenuity ATT&CK Enterprise evaluation; Bitdefender generated an average of 3 alerts to report a single incident to the security operations center, while the median for other vendors was 209 alerts (Bitdefender, 2024). MITRE evaluations do not rank or rate products; these figures rest on the vendor's own statement and should not be read as "came first".
As an authorized Bitdefender channel partner, Sora Yazılım handles GravityZone XDR licensing, sensor onboarding, the design of correlation scenarios, the definition of response procedures and the plan for interoperability with your existing SIEM. You can review the full product family on our Bitdefender solutions page.
What does GravityZone XDR do, and how does it differ from EDR?
The short answer: EDR sees only the endpoint, whereas XDR also ties sources outside the endpoint into the same incident chain. EDR records the processes running on a device, file operations, registry changes and network connections; once the attack leaves that device, the trail breaks. XDR merges signals that look weak in isolation — an anomalous sign-in at the identity provider, a forwarding rule in a mailbox, a new access key in a cloud account and a suspicious process on the endpoint — into a single incident.
The practical difference shows up in the time an analyst spends. A team working with EDR has to search different consoles by hand for the answer to "who started this suspicious PowerShell on this device and where did the credential come from?" GravityZone XDR establishes that relationship through automatic correlation and presents the incident with a real-time extended visualization. According to Bitdefender's official comparison page, automatic correlation and analysis together with real-time extended incident visualization exist only in the XDR tier; these capabilities are not present in the lower tiers (Bitdefender, 2026).
One point should be clarified from the start: XDR is not a backup, a firewall or an email gateway. It is a detection and response layer; it does not replace the prevention layer but is built on top of it. Without a strong prevention stack on the endpoint, XDR only shows more incidents more clearly — it does not stop them from happening.
Which sensors does GravityZone XDR use and what does each of them see?
Beyond the endpoint sensor, the platform collects telemetry through network, productivity, identity, cloud and mobile sensors. According to Bitdefender TechZone documentation, the supported sources include Network, Office 365, Google Workspace, Atlassian Cloud, Identity (Active Directory, Entra ID, Intune), Cloud (AWS, Azure, GCP) and Mobile sensors (Bitdefender TechZone, 2026). The sensors are enabled from the same console; no second management interface appears. The detection examples in the table below are not invented scenarios either — they are the cases named in that same documentation.
| Sensor | Source covered | Detection examples named in the documentation |
|---|
| Endpoint (EDR) | Endpoint activity from the Bitdefender Endpoint Security Tools agent: running processes, network connections, registry changes and user behavior | The execution steps of the attack on the device |
| Network | Network traffic telemetry | Lateral movement attempts and port scanning activity looking for vulnerabilities |
| Active Directory | On-premises directory events | Attacks targeting the Kerberos authentication protocol; lateral movement across the network with a stolen Kerberos ticket |
| Entra ID (Azure AD) | Cloud identity sign-in activity and configuration changes | Unusual sign-in patterns that point to attackers hunting for valid credentials |
| Microsoft Intune | Device management events | Changes to device ownership, policy assignment and Intune application creation |
| Office 365 | User and administrator activity in Microsoft 365 productivity applications | Phishing campaigns; uploading documents with suspicious macros to SharePoint and OneDrive |
| Google Workspace | Google Workspace user and administrator activity | Brute force attacks carried out through unusual failed sign-in attempts; executable file uploads |
| Atlassian Cloud | Atlassian Admin, Jira Cloud and Confluence Cloud activity | Brute force and distributed brute force attempts against user accounts |
| AWS | AWS control plane events | Reconnaissance activity against S3 buckets; multiple failed sign-ins and multi-factor authentication failures |
| Azure | Azure control plane events | Creation or modification of a security rule that could expose applications or resources publicly |
| Google Cloud Platform | GCP control plane events | Deletion of an audit log; deletion of a file store backup, a disk image or a virtual machine instance |
| Mobile | Mobile device telemetry | URL filtering and monitoring of root (privilege escalation) attempts on mobile devices |
Sensor selection is a scoping decision. In an organization running mainly on Microsoft 365, the identity and productivity sensors deliver the highest return, whereas in a multi-cloud software company the cloud sensor comes to the fore. Reviewing sensor scope together with your Microsoft 365 tenant configuration also prevents unnecessary licenses from being purchased. On the licensing side one detail must not be missed. On Bitdefender's official comparison page the "XDR Identity, Network, Productivity" row is not checked for the Business Security Premium and Business Security Enterprise tiers; these sensors appear only in the "Business Security Enterprise + XDR" tier, with the note "with optional XDR sensors". The "XDR Cloud, Business Apps (Atlassian)" row is marked as purchased separately even in the XDR tier (Bitdefender, 2026). In other words, buying Business Security Enterprise does not automatically switch these sensors on, and moving to the XDR tier does not cover every sensor either; which sensor is included in the license must be verified line by line at the quotation stage. Cloud Security Posture Monitoring is likewise listed on the same page as a separate add-on and is used to enrich incident context.
What is the difference between Business Security Enterprise and GravityZone XDR?
The clear difference is this: Business Security Enterprise correlates across endpoints, while GravityZone XDR brings sources outside the endpoint into the same correlation. The Enterprise tier delivers a mature EDR with threat hunting, anomaly defense, easy investigation and one-click remediation; but the identity, productivity, network and cloud sensors together with automatic cross-source correlation are unlocked in the XDR tier. The table below summarizes the distribution on the vendor's official comparison page.

Source: Bitdefender official business products comparison page (Bitdefender, 2026). The decision rule is simple: if you have a team to review the alerts and your attack surface is not limited to the endpoint, move to the XDR tier. If you do not have such a team, buying XDR on its own will not produce results — in that case a managed service is the sounder investment. We cover the endpoint side of the tier comparison on our Business Security Enterprise page, and the prevention-focused lower tier on our Business Security Premium page.
What do independent tests and analyst reports show about Bitdefender's XDR side?
The short answer: the results on the detection and response side are strong, but the label "leader" does not apply to every report. In The Forrester Wave: Extended Detection And Response Platforms, Q2 2024, a 22-criterion evaluation, Bitdefender was positioned as a "Strong Performer" and received the highest possible score in the Innovation & Roadmap, Analyst Experience, AI & Machine Learning, Endpoint Protection and Product Security criteria (Bitdefender, 2024). The same vendor had been positioned as a "Leader" on the endpoint security side in The Forrester Wave: Endpoint Security, Q4 2023, among 13 providers and 25 criteria (Bitdefender, 2023). The picture at Gartner is different: in the Magic Quadrant for Endpoint Protection dated 26 May 2026, 13 vendors were evaluated and Bitdefender was positioned in the "Visionary" quadrant for the fourth consecutive time (Bitdefender, 2026). The frequently repeated phrase "Gartner Leader" is not accurate.
There are independent laboratory results on detection quality as well. In AV-Comparatives' Endpoint Prevention & Response test of June–September 2025, 12 products were subjected to 50 targeted attack scenarios and GravityZone Business Security Enterprise 7.9 was one of the 10 products that received certification (AV-Comparatives, 2025). In the NGFW Egress C2 certification test conducted in November 2025, the same product blocked the malicious traffic in all 10 command-and-control scenarios and was rated "APPROVED" (AV-Comparatives, 2025). Stopping command-and-control traffic is one of the stages where XDR correlation proves most useful.
The figures on the MITRE side could only be verified from the vendor's announcement and should be read accordingly: in the 2024 evaluation Bitdefender reported 91% overall analytic coverage and a total of 6 false positives; 100% coverage and zero false positives were reported in Linux and macOS environments. The emulated threats were the Cl0p and LockBit ransomware families together with North Korea-linked macOS attacks (Bitdefender, 2024). On the endpoint prevention side, in AV-TEST's November–December 2025 corporate Windows 11 test, Business Security Enterprise 7.9 earned the "TOP PRODUCT" certification with a total of 17.5/18 — 6.0 for protection, 5.5 for performance and 6.0 for usability (AV-TEST, 2025).
How does GravityZone XDR compare with Trend Micro Vision One?
Both belong to the same category: XDR solutions that unify endpoint, identity, email/productivity, network and cloud telemetry on a single platform. The difference emerges not in the product brochure but in the organization's existing stack and operating model. We do not publish a table on this page placing the feature lists of the two products side by side, because the module names on vendor pages change with package and version, and every line carried over without verification produces a wrong purchasing decision. What can be said objectively is this: in an organization already using the Bitdefender endpoint agent, GravityZone XDR goes live with less friction because it does not require replacing the agent.
The right comparison is made not through brand names but through four questions: (1) which endpoint agent do you currently run and what would it cost to replace it, (2) which sensors will actually be brought online and what do they cost in license terms, (3) who will review the alerts — an in-house team or a managed service, and (4) what are your data retention and data residency requirements. Sora Yazılım is an authorized channel partner of both brands; we produce an impartial comparison for your environment and, where needed, run pilot deployments of both products. We describe the Trend Micro counterpart in detail on our Trend Vision One page.
The impression that XDR replaces the network layer is another common mistake. The network sensor collects telemetry and contributes to correlation; segmentation, IPS and inspection of branch-to-headquarters traffic are a separate layer. For that layer we position FortiGate firewalls as complementary. Similarly, email remains the channel where attacks most often begin; the XDR productivity sensor sees the anomaly in the mailbox but does not stop the malicious message before delivery. That task requires the GravityZone Email Security layer.
Alert fatigue and response: how does XDR operation work in practice?
The promise of XDR is not more data but fewer, more meaningful incidents. The platform merges signals from different sensors into a single incident record; instead of hundreds of alerts, the analyst sees one incident chain. The gap between 3 alerts and a median of 209 in Bitdefender's own statement about the 2024 MITRE evaluation is precisely the result of that design choice. Even so, no XDR produces results unless the organization defines who reviews an alert, within what time and with what authority.
Response authority and level of automation
Three levels are defined during onboarding: notification only, response subject to approval, and fully automatic response. On critical servers, full automatic isolation carries the risk of a production outage and is therefore usually made subject to approval; on user laptops, automatic isolation is a reasonable default. Designing this distinction per policy group is the step most often skipped in XDR projects — and the one that makes the biggest difference. Because the protection architecture on the server side is different, we plan the GravityZone Security for Servers side together with it.
If there is no in-house team: the managed service option
Most mid-sized organizations in Turkey do not have a security team on duty 24/7. In that case the XDR capability is taken together with a managed service. Bitdefender MDR runs 24/7 in a "follow-the-sun" model with three security operations centers in the United States (Texas), Romania (EU) and Singapore, delivered by a team of more than 285 security analysts, researchers and threat hunters (Bitdefender, 2026). The service has two tiers; dark web monitoring, a dedicated Security Account Manager and the quarterly business review are available only in the MDR PLUS tier (Bitdefender B2B Support, 2026). We detail the scope on our Bitdefender MDR page.
Are SIEM and XDR alternatives to each other?
No, they do different jobs. A SIEM collects logs from all sources, retains them for a long time and serves as the primary evidence store for compliance reporting. XDR correlates telemetry from selected sources to produce detection and response. If you have invested in a SIEM, XDR does not replace it; it feeds its incident output into the SIEM and supports SOC processes. If retention is critical, it must be accounted for from the start: Bitdefender's official comparison page lists data retention as a separately purchased add-on under the heading "Data Retention (90, 180, 365 days)" (Bitdefender, 2026). Because the default retention period is not stated on that page, we do not publish a fixed number of days here; we verify the retrospective investigation window you need against current documentation at the quotation stage.
KVKK, data residency and deployment: how is GravityZone XDR rolled out in Turkey?
Article 12 of Law No. 6698 on the Protection of Personal Data (KVKK, Turkey's data protection law) obliges the data controller to take appropriate technical and administrative measures to prevent unlawful access to personal data and to ensure that the data is safeguarded. XDR delivers concrete value on the detection and response side of that obligation: a record of which account accessed which data and when, the ability to reconstruct the incident chain when a breach is suspected, and the ability to document the response. Being able to answer "what happened, when did it happen, which data was affected" in cases requiring a data breach notification is as much a legal requirement as a technical capability.
In organizations sensitive about data residency, the choice of architecture becomes important. The GravityZone cloud console is a multi-region SaaS service hosted by Bitdefender. The on-premises installation is delivered as a self-configuring, hardened Ubuntu-based virtual appliance in OVA, XVA, VHD, OVF and RAW formats; the Database, Update Server, Endpoint Communication Server, Endpoint Events Processing Server, Web Console, Incidents Server and Report Builder roles can be distributed across separate appliances for scaling (Bitdefender B2B Support, 2026). Our DevOps and infrastructure services come into play for appliance placement, redundancy and capacity planning. For organizations that also want to manage vulnerability remediation from the same console, we recommend the GravityZone Patch Management add-on.
In practice the rollout order works like this: first the endpoint EDR sensor is matured and false positives are weeded out, then the identity sensor is switched on because it usually delivers the highest return, and finally the productivity and cloud sensors are added. Turning them all on in the same week drowns the team in noise from day one and leads to the project being abandoned. The console interface is not available in Turkish; we provide technical support, documentation transfer, response guidance during incidents and administrator training in Turkish.
