Which endpoint protection fits a self-hosted Wazuh or Elastic Security shortlist
If your regulated team needs host protection that blocks threats, not just reports them, you need to check that choice before you check anything else. Wazuh's documented endpoint features center on detection and automated response: file integrity monitoring, malware detection, vulnerability detection and active response, which runs actions such as blocking brute-force attacks or disabling a user account. Elastic Defend lists malware and ransomware prevention and host isolation under the Enterprise tier of Elastic's self-managed subscriptions, so those preventive controls depend on a paid subscription. The overall picture is in our Wazuh vs Elastic Security comparison.
Start by writing down which outcome each host event must produce. If an alert that reaches an analyst within your response window is enough, Wazuh's file integrity monitoring, rootkit checks, and VirusTotal and YARA integrations may cover the requirement, provided your team can run the response playbooks. If the requirement is to stop a ransomware process or isolate a compromised host automatically, confirm in writing whether Wazuh active response scripts meet it for your operating systems, and price Elastic Enterprise against that need. Ask Elastic for the exact Enterprise feature list for your deployment model, since the subscriptions page is the reference for tier contents.
Check the agent coverage before you compare features. Wazuh agents run on Linux, Windows, macOS, Solaris, AIX and HP-UX, and Elastic Agent with Elastic Defend must be verified against your own operating system and kernel list. Also confirm whether your team's blocking policy can be tested in a staging ring first, because an incorrect automated response on a production server causes its own outage. Document the result, including who approves isolation actions and how they are reversed.
How each platform covers file integrity, malware, response and vulnerabilities
This table maps the endpoint functions teams compare most often, from file integrity monitoring to host isolation, against what Wazuh documents and what Elastic lists under its Enterprise tier. Where a cell says confirm, the documentation available here does not settle the answer, so check with the vendor or in a test deployment before relying on it. The main takeaway is that Wazuh documents detection and automated response in its open-source core, while Elastic's prevention and host isolation features are paid Enterprise capabilities.
| Capability | Wazuh | Elastic Security |
|---|---|---|
| Agent platforms | Linux, Windows, macOS, Solaris, AIX and HP-UX agents | Elastic Agent with Elastic Defend; confirm OS coverage in the support matrix |
| File integrity monitoring | Documented, including Windows Registry keys | Not covered in the endpoint listing reviewed; confirm before relying on it |
| Malware detection | Detection combining FIM, rootkit checks, threat intelligence lists, VirusTotal and YARA integrations | Malware and ransomware prevention listed under Enterprise; confirm the prevention mode per policy |
| Active response | Automated actions on events, such as blocking brute-force sources or disabling a user account | Interactive response console listed; confirm whether automated response actions are available |
| Host isolation | Not listed in the Wazuh capabilities documentation; confirm | Listed under Enterprise tier for self-managed deployments |
| Memory threat protection | Not listed in the Wazuh capabilities documentation; confirm | Listed among Elastic Security capabilities; confirm the tier that includes it |
| Vulnerability detection | Correlates agent software inventory with CTI platform or offline repository data | Not covered in the endpoint listing reviewed; confirm before relying on it |
| Licensing for these features | Included in GPL-2.0 server and agent with no feature tier | Prevention and host isolation sit in Enterprise; Platinum is closed to new self-managed buyers |
What each platform blocks versus what it alerts on
Wazuh active response runs automated actions when an event matches a rule, such as blocking a brute-force source or disabling a user account. The action is a response triggered by detection, so its effect depends on the rule that fired, the agent's host configuration and the platform it runs on. Treat it as an automated reaction you configure and test, not as a general prevention layer that stops every malicious process before it runs.
- Configured per rule: Each active response is tied to a rule or group of rules, so coverage is only as broad as the rules you enable.
- Typical examples: Documented uses include blocking brute-force attempts and disabling an account, which act after the triggering event is logged.
- Timing: The response follows detection, so there can be a delay between the first malicious action and the block.
- Custom scripts: Your own response scripts can run on the agent, which means their behavior and failure handling are your responsibility.
- Scope: Active response does not replace a dedicated prevention product for malware that must be stopped before execution.
Confirm in the Wazuh capabilities documentation exactly which response types apply to your OS and which rules trigger them, and test each one in a staging environment.
Wazuh's malware detection combines file integrity monitoring, rootkit behavior checks, threat intelligence lists, VirusTotal and YARA integrations, and collection of ClamAV and Windows Defender logs. Most of these signals are detection: Wazuh records and alerts on changes and matches, and the active response path is what can act on them. File integrity monitoring tells you that a file or Windows Registry key changed, not whether the change was malicious or whether it was blocked.
- FIM alerts: Changes to monitored files and Windows Registry keys generate alerts, which supports detection and investigation.
- Rootkit checks: Rootkit behavior checks report suspicious host conditions for review.
- Third-party engines: VirusTotal and YARA integrations and ClamAV or Windows Defender logs surface findings from other tools, and Wazuh does not block by default based on them.
- Threat intelligence lists: Matches against indicator lists raise alerts that analysts or response rules must act on.
- Blocking path: Any blocking must be configured through active response and tested against the specific file or hash type.
Confirm which of these signals can trigger active response in your Wazuh version, and document that the default is alerting unless you have configured otherwise.
Elastic Defend includes endpoint malware and ransomware prevention and memory threat protection, which are prevention controls delivered through Elastic Agent and managed centrally through Fleet. Elastic lists malware and ransomware prevention under its Enterprise tier for self-managed deployments, so the prevention features you need determine which subscription you buy. Prevention modes are set per policy, and what gets blocked depends on the protection settings you choose.
- Malware and ransomware prevention: Listed as an Enterprise feature for self-managed deployments, and designed to stop execution rather than only report it.
- Memory threat protection: A separate prevention capability listed among Elastic Security features, which you should verify against your OS and policy.
- Policy-level modes: Prevention and detection-only settings are applied through policies in Fleet, so the same rule can behave differently across host groups.
- Detection rules: The detection engine's rules alert, and they are separate from the prevention controls that block.
- Subscription boundary: Confirm the tier before you plan around any prevention feature in a self-managed deployment.
Confirm the exact prevention behavior for each protection type and OS in the Elastic Security documentation and the current subscriptions page before you commit.
Host isolation is an Elastic Defend response action that cuts a host off from the network, and Elastic lists it under the Enterprise tier for self-managed deployments. Isolation is a containment step an analyst or automated process triggers, and it is distinct from blocking a single process or file. Confirm what traffic remains allowed during isolation, such as the management channel to Fleet, before you rely on it in an incident.
- Containment scope: Isolation applies to the whole host rather than to one file or connection.
- Analyst-triggered: It is typically invoked from the case or response console, which requires staff time during an incident.
- Interactive response console: Listed among Elastic Security capabilities, and it supports manual investigation alongside containment.
- Recovery: Releasing an isolated host is a documented step you should rehearse.
- Tier cost: Because it sits in Enterprise, the subscription affects which teams can use it.
Confirm the isolation exceptions, recovery steps and tier requirements in the Elastic Security documentation and test them on a non-production host.
Across both platforms, the core split is that Wazuh is strongest on detection and alert-driven response, while Elastic Defend adds prevention and isolation controls in its paid tier. Both can act automatically, but the trigger, the scope of the action and the tier that includes it differ. Writing your requirements as a list of specific events, expected actions and approval steps makes the comparison concrete.
- Wazuh: Detection through FIM, malware signals and rules, with active response for configured automated actions.
- Elastic Defend: Prevention for malware and ransomware, memory threat protection and host isolation, with Fleet-managed policies.
- Tier boundary: Elastic prevention and isolation sit in Enterprise for self-managed deployments.
- Licensing: Wazuh server and agent are GPL-2.0, while Elastic's default distribution is under the Elastic License 2.0.
- Scope of this page: Endpoint enforcement only, not network blocking or SIEM correlation.
Before you choose, confirm enforcement behavior per rule type and per OS in each product's documentation, and run a tabletop test of one brute-force and one ransomware scenario against both.
Which factors change the endpoint result in practice
The same endpoint goal can produce different results depending on a few conditions. The cards below cover the factors that most often decide whether Wazuh or Elastic Security fits, and what to verify before you commit.
OS coverage across the fleet
Wazuh agents run on Linux, Windows, macOS, Solaris, AIX and HP-UX, so legacy Unix hosts stay in scope. Elastic Defend covers the platforms listed in its own support matrix, which should be checked against your exact OS versions. If Solaris, AIX or HP-UX systems hold regulated data, confirm endpoint protection and file integrity coverage on each before choosing Elastic for prevention. Ask both vendors for a written support matrix that names your kernel and OS builds.
Blocking versus alerting requirements
Wazuh's malware detection and active response are built around detection, correlation and automated responses such as blocking brute-force sources or disabling an account. Elastic Defend adds malware and ransomware prevention, memory threat protection and host isolation that act on the endpoint. If your policy requires a process to be stopped before execution, Elastic's prevention features are the deciding factor. If alerts plus scripted response meet your standard, Wazuh may be enough. Document which events must be blocked in real time.
Enterprise tier for prevention
Elastic lists endpoint malware and ransomware prevention, host isolation and SAML or OpenID Connect single sign-on under its Enterprise tier on the self-managed subscription page. Platinum no longer sells to new customers, so a self-managed buyer who needs these features must plan for Enterprise. Wazuh's core agent, FIM and active response features are open source under GPL-2.0. Get Elastic's current quote for your node count and confirm which features each subscription includes before budgeting.
Elastic Cloud or self-managed hosting
Elastic Security runs on Elastic Cloud or self-managed clusters. Choosing Elastic Cloud moves cluster operations to Elastic but places endpoint telemetry in a vendor-hosted environment, which may conflict with data residency rules in regulated sectors. Self-managed Elastic needs your own cluster nodes, upgrades and storage planning. Wazuh is self-hosted by default, and Wazuh Cloud is a separate managed option. Confirm where endpoint data may reside before you compare running costs.
Offline vulnerability data needs
Wazuh vulnerability detection correlates agent software inventory with data from the Wazuh CTI platform or an offline vulnerability repository. Air-gapped or restricted networks must use the offline path, and someone must refresh that repository on a schedule. Elastic Defend's vulnerability handling depends on how your Elastic deployment is built, so confirm offline update options with Elastic before assuming parity. If your hosts cannot reach the internet, make the update process a documented task owned by a named team.
Analyst capacity for rule tuning
Both platforms ship detection content, but Wazuh's ruleset includes over 3,000 built-in rules and decoders mapped to MITRE ATT&CK, and Elastic's prebuilt detection rules update automatically from its public repository. Each produces alerts that must be tuned against your environment. A small team with few analysts may struggle to triage a large alert volume from either platform. Ask how many analysts will own rule changes, exceptions and alert suppression, and budget that time before choosing the platform.
What the Enterprise tier and GPL-2.0 license mean for endpoint features
The endpoint feature gap is a licensing question as much as a technical one. Wazuh server and agent are distributed under GPL-2.0 with an OpenSSL linking exception, so the agent and server code you run carry no per-seat or per-feature license fee from the project. On the Elastic side, the self-managed subscriptions page places endpoint malware and ransomware prevention, host isolation and SAML or OpenID Connect single sign-on under the Enterprise tier. Before comparing blocking behavior, confirm which of those controls your team needs in production, because they are not in the free Basic tier.
Elastic's Platinum tier, which carried the detection engine and case management, is no longer sold to new customers according to the same page. A new self-managed buyer therefore chooses between Basic, Enterprise or moving to Elastic Cloud. Ask the vendor in writing which tier includes each control you plan to rely on, whether host isolation and ransomware prevention are licensed per endpoint or per cluster, and whether the quote covers Elastic Defend deployment support. Also ask how Enterprise pricing changes if you add endpoints or nodes later.
The recurring costs differ in shape. Wazuh's recurring costs are the staff time to tune rules, patch the indexer, server and dashboard, and keep agents current across the fleet, plus the infrastructure those components run on. Elastic's recurring costs add the subscription itself, which is the item to request as a line in the quote. For either path, ask for one-time items (installation, initial rule and policy tuning, integration with identity) separated from annual items (subscription renewal, support, retainer hours). A fixed-scope DeployOpen quote follows from the written scope, so list the endpoint operating systems and the controls you need in that scope.
How to test endpoint blocking and detection in your own environment
This sequence shows, on your own hosts, which endpoint events each platform blocks, which it only alerts on, how long alerts take to appear and what an operator must do to act on them. Run it in a cyber range or isolated lab before relying on either product in production.
Confirm agent and server versions for the fleet
The platform owner lists every operating system in the test fleet and checks which Wazuh agent and server versions and which Elastic Agent, Elastic Defend and Elastic Stack versions support each one. Use the current Wazuh 4.14 release line and the current Elastic 9.x release lines as the starting point, then confirm support for each OS and your subscription tier with the vendor. The step is done when a written version matrix exists for both platforms and every test host appears in it.
Build isolated lab hosts and a baseline
The security engineer deploys matching test hosts in a cyber range or segmented lab with no route to production, installs one Wazuh stack and one Elastic Security stack, and enrolls the same hosts into each. Capture the baseline state of monitored directories, the Windows Registry keys in scope and the running process list before any test. The step is done when both consoles show every test host as connected and the baseline snapshot is stored with a timestamp.
Run controlled file integrity changes
The tester makes a defined set of changes to monitored paths: creating a file, modifying a configuration file, changing permissions, and editing a monitored Windows Registry key. Record the exact time of each change and the expected event. Wazuh file integrity monitoring should raise an alert for each change, while Elastic should be checked for the equivalent file events and whether any change is prevented. The step is done when a table lists each change, whether each platform alerted, whether it blocked anything, and the observed time to alert.
Detonate a known malware sample in isolation
The security engineer runs a known malware sample from a recognized test corpus on a disposable lab host, with network egress disabled and a snapshot taken beforehand. Observe whether each agent or Elastic Defend prevents execution, quarantines the file, or only records an alert, and whether Wazuh malware detection signals such as YARA or ClamAV log collection fire. The step is done when the host is restored from snapshot and the outcome for each platform is recorded as blocked, alerted or missed.
Simulate brute-force logins to test active response
The tester generates repeated failed authentication attempts against a lab service from a single source, at a rate agreed with the lab owner. Confirm whether the Wazuh rule fires and whether the configured active response blocks the source, and confirm whether Elastic raises a detection alert and what response, if any, it takes. Record which steps need an operator to approve or reverse a block. The step is done when both the alert and the block state are captured and the source is unblocked afterward.
Run an isolation drill on the Elastic host
The incident responder isolates one lab host through the Elastic Security console, using host isolation, and then confirms from a separate management path that the host cannot reach other lab systems. Record the operator clicks or API calls needed, then release the host and confirm restored connectivity. The step is done when isolation and release are both logged with timestamps and the responder has noted which actions require a licensed Elastic tier and which the lab account can perform.
Compare the results and record operator effort
The engineering lead combines the logs from all tests into one matrix with columns for event type, platform, blocked, alerted only, missed, time to alert and the operator steps needed to act. Mark any result that depended on a paid feature or a manual action. Confirm the outcomes with each vendor before drawing conclusions, since product behavior can change between releases. The step is done when the matrix is reviewed and signed off and any gaps are logged as questions for the vendor.
What running endpoint protection costs in people and upkeep
The largest recurring cost of either platform is the people who tune rules, maintain policy and clear exceptions, not the software itself. Wazuh has no license fee, but its ruleset ships over 3,000 built-in rules and decoders mapped to MITRE ATT&CK, and someone must decide which of them fire on your fleet, which custom decoders you need for in-house applications, and which alerts should trigger active response. Expect that work to start during setup and continue for as long as the rules run. Elastic Defend asks for a similar review of prebuilt detection rules and their customization, plus policy design in Fleet, but its endpoint prevention features (malware and ransomware prevention, host isolation) sit under the Enterprise tier, so the subscription decision comes with its own review cycle.
Upkeep is also a patching question. Wazuh shipped 4.14 patch releases on 17 March, 23 April, 1 July, 29 July, 23 September and 14 October 2026, so the team should plan a recurring window for agent and server upgrades and test each patch against a non-production agent group first. On the Elastic side, the EOL page lists end of maintenance for the 8.x line on January 15, 2027 and for the 9.x line on October 15, 2027, so a self-managed deployment that stays on 8.x will need a version move inside that horizon. Ask Elastic and Wazuh to confirm the upgrade path for the version you plan to run, because the stack upgrade is usually larger than a Wazuh patch.
Staff for policy and exception handling should be named before go-live. Ask who approves a host isolation action in Elastic or an active response block in Wazuh, who owns exceptions for legitimate tools that look like malware, and how often those exceptions are reviewed. Those decisions recur for the life of the deployment and are often the difference between an endpoint program that blocks and one that is ignored. Ask any implementation partner to price these roles in the written scope, separating the one-time build of rules and policies from the ongoing review workload you will carry after handover.
Questions buyers ask about endpoint protection on Wazuh and Elastic
Can Wazuh block malware on an endpoint?
Wazuh detects malware and can run automated responses, but its documented capabilities centre on detection and active response rather than a dedicated prevention engine that stops execution at the endpoint. Its malware detection combines file integrity monitoring, rootkit behavior checks, threat intelligence lists, VirusTotal and YARA integrations, and collection of ClamAV and Windows Defender logs. Active response can run actions such as blocking a brute-force source or disabling a user account when a rule fires. Whether a given active response step stops a specific threat in time depends on the rule, the action script and the host. Before you rely on Wazuh for blocking, test the exact response path against your own malware samples and confirm with Wazuh how each action is executed on your operating systems.
Is Elastic Defend included in the free Elastic tier?
No. Endpoint malware and ransomware prevention and host isolation are listed under Elastic's Enterprise tier on the self-managed subscriptions page, so they are not part of the free Basic tier. Elastic Defend is the endpoint component of Elastic Security and is managed centrally through Fleet with Elastic Agent. Basic does include free security features such as TLS, the file and native user realms and role-based access control, but those do not add endpoint prevention. Confirm the current tier mapping on Elastic's subscriptions page before you finalize a design, because tier contents change over time.
What does Elastic Enterprise cost in effort and license terms?
The license cost of Elastic Enterprise is set through Elastic's commercial process, and the researched sources do not give a price, so ask Elastic for a written quote covering the node count, data volume and support level you need. Effort drivers include running the Elasticsearch cluster, which needs at least three master-eligible nodes for high availability, plus sizing for hot, warm and cold data tiers, Fleet policy management, and tuning of prebuilt rules. Also confirm the support window: Elastic lists end of maintenance for the 8.x line on January 15, 2027 and for the 9.x line on October 15, 2027. Ask whether your license covers self-managed and Elastic Cloud use, and what happens to features if you move tiers later.
Does Wazuh offer ransomware prevention?
Wazuh does not document a ransomware prevention feature in the capabilities material used for this comparison, so do not assume it blocks encryption activity. What it offers is file integrity monitoring, malware detection signals, command monitoring and active response, which can help you spot suspicious file changes and trigger containment actions. Whether those signals catch a specific ransomware family in time depends on your rules, your monitored directories and your response playbooks. Elastic lists malware and ransomware prevention under Enterprise, so the two products differ on this point. Ask Wazuh to confirm any ransomware behavior in writing, and validate it with controlled tests in a lab that mirrors your endpoints.
How long does an endpoint pilot take and what does it need from the team?
The duration depends on the number of endpoint types, the test cases you define and how much tuning your team wants before a go or no-go decision, so no fixed timeline applies to every environment. A useful pilot needs a representative set of Windows, Linux and macOS hosts, a dedicated test indexer and server, a named owner for detection tuning, and a security engineer who can run controlled malware and response tests. Agree the success criteria in writing before the pilot starts, including which events must alert, which must be blocked, and what false-positive rate is acceptable. Ask any implementation partner to scope the pilot in a fixed written plan with deliverables and dates.
Can DeployOpen run the endpoint test plan for us?
DeployOpen plans, implements, integrates, hardens and supports self-hosted open-source platforms inside your own infrastructure, and it runs security testing, including testing of cloud and infrastructure. Most engagements are fixed-scope, with scope, deliverables and timelines agreed in writing before work starts. Ongoing support and continuous testing are available as retainers. For this comparison, the work would include deploying the chosen platform in your environment, defining detection and response test cases, and documenting results. DeployOpen does not publish a price list, so a quote follows from the written scope, which should name the platforms, endpoint types, number of hosts and the test cases to be covered.
When endpoint protection should decide the choice
Let endpoint requirements decide this choice only when you can state them precisely. Choose Wazuh if your endpoint requirement is detection and response: file integrity monitoring including Windows Registry keys, malware detection that combines rootkit checks, threat intelligence lists, VirusTotal and YARA integrations and ClamAV or Windows Defender logs, vulnerability detection built on agent software inventory, and active response scripts such as blocking brute-force sources or disabling an account. Add the GPL-2.0 license to that list if license terms are a hard constraint, since Wazuh server and agent are GPL-2.0 with an OpenSSL linking exception. Confirm with Wazuh which of these checks cover your operating systems, because agent coverage differs by platform.
Choose Elastic Security if your requirement is managed prevention: blocking malware and ransomware at the endpoint, memory threat protection and host isolation through Elastic Defend. Elastic lists malware and ransomware prevention, host isolation and SAML or OpenID Connect single sign-on under the Enterprise tier of its self-managed subscriptions, so that tier must be acceptable for the license spend and the agent footprint. Platinum is no longer sold to new self-managed customers, so the practical paid choice is Enterprise or Elastic Cloud. Confirm the current price and terms in writing with Elastic before you decide.
Treat the endpoint comparison as one input. The wider SIEM comparison covers search backends, storage, cluster sizing and the rest of the stack, so use this section to settle the endpoint question and then check the remaining requirements against that comparison. If a requirement is an automated block that must happen before a human responds, verify on a test host how each product's response actions behave before you commit.
