The nine EDR solutions compared here are CrowdStrike Falcon, Microsoft Defender for Endpoint, SentinelOne Singularity, Palo Alto Cortex XDR, Elastic Security, Sophos Endpoint (Intercept X), TrendAI Vision One, Bitdefender GravityZone and Cynet. The deciding criterion is the false positive rate your team can absorb: choose the platform whose verified detection accuracy fits your analyst headcount, then check its pricing model and network visibility.
Endpoint detection and response monitors laptops, desktops, servers and cloud workloads to detect, investigate and respond to threats. This guide compares the nine on detection approach, independent test results, deployment, pricing model and team size, with a buying checklist and notes for UK organisations.
EDR solutions at a glance
Test results are from the AV-Comparatives Business Security Test March-June 2024, the most recent round in which most of these vendors were tested side by side. The product tested is named because it is not always the vendor's full EDR tier. "False alarms" there means clean websites and files wrongly blocked, not the volume of EDR alerts your analysts will see.
| Vendor | Best for | Deployment | Independent test result (AV-Comparatives 2024) | Pricing model |
|---|---|---|---|---|
| CrowdStrike Falcon | Endpoint-first teams wanting strong threat intelligence | SaaS | 98.8% real-world, 99.1% malware, 21 false alarms (Falcon Pro) | Per device; Falcon Enterprise (first tier with EDR) listed at US$184.99 per device, annual |
| Microsoft Defender for Endpoint | Organisations already on Microsoft 365 E5 | SaaS in the Microsoft Defender portal | 98.2% real-world, 99.4% malware, 0 false alarms (Defender Antivirus with Endpoint Manager) | Included in Microsoft 365 E5 and E5 Security, or standalone Plan 2 |
| SentinelOne Singularity | Small teams that want automated containment and rollback | SaaS | Not in this round | Per endpoint; Singularity Complete listed at US$179.99 a year (5 to 100 workstations) |
| Palo Alto Cortex XDR | Palo Alto firewall and Prisma Cloud estates | SaaS | Not in this round | Quote-based; not published on the product page |
| Elastic Security | Mature teams that want open rules and self-hosting | Elastic Cloud (serverless or hosted) or self-managed | 99.6% real-world, 99.5% malware, 0 false alarms (Elastic Security) | Usage-based (serverless) or resource-based (hosted); self-managed by subscription |
| Sophos Endpoint (Intercept X) | Small and mid-sized teams wanting strong defaults and optional MDR | SaaS console | 98.0% real-world, 97.1% malware, 2 false alarms (Intercept X Advanced) | Quote-based; not published on the product page |
| TrendAI Vision One | Teams consolidating EDR, SIEM and SOAR with one vendor | SaaS, with sovereign and private cloud options listed | Not in this round | Quote-based; not published on the product page |
| Bitdefender GravityZone | Buyers needing an EU-hosted or on-premises console | Cloud, EU-hosted or on-premises console | 99.8% real-world, 99.2% malware, 1 false alarm (Business Security Premium) | Tiered packages from Small Business to Enterprise; quote-based |
| Cynet | SMEs and MSPs that want a managed team included | SaaS | Not in this round | Packages; prices not published on the platform page |
Reading the protection numbers
Two facts belong next to the protection rates.
- False alarms. Microsoft Defender and Elastic recorded zero false alarms; CrowdStrike Falcon Pro, at 98.8%, recorded 21 in the same run. A false alarm here is a clean website or business application blocked. Each one stops a member of staff working, raises a support ticket and takes analyst time to clear, and research with SOC teams links alert volume to critical threats being overlooked (Baruwal Chhetri et al., ACM Transactions on Internet Technology, 2024).
- What the test measures. Each case feeds one malicious URL or file to one machine and records whether the product blocked it, with half credit where the user had to decide (AV-Comparatives methodology). It measures prevention on a single endpoint. It does not test what happens once an attacker is inside: lateral movement, command-and-control traffic or the misuse of a stolen identity, so pilot any shortlisted product on your own estate.
Vendors marked "not in this round" did not enter that AV-Comparatives test. Several take part in other public evaluations, such as the MITRE ATT&CK Evaluations; ask each vendor for its latest independent result and read the method before comparing numbers across tests.
What Is EDR and Why Does It Matter?
Endpoint detection and response (EDR) is a category of security technology that continuously monitors endpoints, laptops, desktops, servers, and cloud workloads, to detect, investigate, and respond to threats. EDR provides the deep visibility into endpoint activity that traditional antivirus cannot: process trees, command-line arguments, network connections, file operations, and registry changes.
EDR matters because endpoints are where attacks execute. Whether the initial access comes through phishing, a vulnerable web application, or a compromised third-party tool, the attacker ultimately needs to run code on an endpoint. EDR provides the detection and response capabilities needed to catch and contain that activity.
However, standalone EDR has well-documented limitations. It sees only what happens on the endpoint, lacking visibility into network-layer activity, cloud API calls, and identity events. An independent assessment of state-of-the-art EDR products against advanced persistent threat attack scenarios found that they failed to prevent and log the bulk of the attacks tested, and described methods for tampering with the EDR telemetry providers themselves (Karantzas and Patsakis, Journal of Cybersecurity and Privacy, 2021). This is why many teams add network, identity and cloud evidence to endpoint telemetry.
How We Evaluated EDR Solutions
We assessed each EDR platform against six criteria that reflect the real-world priorities of mid-market security teams:
- Detection accuracy: The quality and breadth of detection capabilities, including coverage of MITRE ATT&CK techniques, behavioural analysis depth, and machine-learning sophistication
- False positive rate: The ratio of genuine alerts to noise. High false positive rates waste analyst time and erode trust in the platform; the volume of alerts is now recognised in the research literature as a cause of overlooked critical threats (Baruwal Chhetri et al., ACM Transactions on Internet Technology, 2024)
- Deployment complexity: How quickly the solution can be deployed across an endpoint estate and how much ongoing administrative effort it requires
- Pricing model: The transparency and predictability of pricing, including whether costs scale with data volume, endpoint count, or feature tiers
- Additional capabilities: Whether the platform extends beyond traditional EDR to include network detection, cloud visibility, SIEM, or SOAR functionality
- Team size required: The minimum security team needed to operate the platform effectively
1. CrowdStrike Falcon
Overview
CrowdStrike Falcon is one of the most widely deployed cloud-native EDR platforms. Built on the Falcon platform, it provides endpoint protection, threat intelligence, and managed threat hunting. CrowdStrike has expanded into XDR, IT hygiene, and log management (Falcon LogScale) to broaden its platform capabilities.
Detection Approach
CrowdStrike uses a combination of signature-based detection, behavioural analysis (indicators of attack, IOAs), and machine-learning models. The platform benefits from the CrowdStrike Threat Graph, which correlates telemetry across its entire customer base to identify emerging threats.
Key Strengths
- Strong threat intelligence: CrowdStrike's adversary-tracking programme (named threat actor groups) and the Threat Graph provide excellent contextual intelligence that enriches detections
- Cloud-native architecture: Fully SaaS-delivered with no on-premises infrastructure required. The lightweight Falcon agent has minimal endpoint performance impact
- Managed services: Falcon Complete provides 24/7 managed detection and response for organisations that want to outsource SOC operations
- MITRE ATT&CK coverage: CrowdStrike takes part in the public MITRE ATT&CK Evaluations; read the latest round for the current picture rather than relying on a summary
Key Limitations
- Complex pricing tiers: The CrowdStrike pricing page lists Falcon Go, Pro, Enterprise and Complete Next-Gen MDR bundles priced per device, plus Falcon Flex and Elite options. Understanding which capabilities are included in each tier requires careful evaluation
- Endpoint-focused: While CrowdStrike has expanded into XDR and log management, the core platform remains endpoint-centric. Full network visibility requires additional modules or third-party integrations
- Cost at scale: Enterprise-tier licensing with add-on modules can become expensive, particularly for organisations that need the full feature set
Best For
Organisations that prioritise high-fidelity endpoint detection with strong threat intelligence and are willing to invest in additional modules for broader visibility.
2. Microsoft Defender for Endpoint
Overview
Microsoft Defender for Endpoint is the endpoint pillar of Microsoft's wider security ecosystem. It provides endpoint protection, vulnerability management, and attack surface reduction across Windows, macOS, Linux, iOS, and Android devices.
Detection Approach
Defender for Endpoint uses Microsoft's cloud-based security intelligence, behavioural monitoring, and machine-learning models. It benefits from telemetry across Microsoft's vast customer base and integrates with Microsoft Defender XDR for cross-domain correlation.
Key Strengths
- Microsoft ecosystem integration: Smooth integration with Azure AD, Microsoft 365, Microsoft Sentinel, and Microsoft Defender for Cloud. For Microsoft-centric organisations, this integration is a significant advantage
- Bundled licensing: Microsoft documents that Microsoft 365 E5 and E5 Security include Defender for Endpoint Plan 2, so organisations on those licences get it without a further purchase. This makes it highly cost-effective for existing Microsoft customers
- Broad platform support: Covers Windows, macOS, Linux, iOS, and Android from a single console
- Attack surface reduction: Built-in attack surface reduction rules block risky behaviour such as Office applications spawning child processes or injecting code, before threats reach the detection layer
Key Limitations
- E5 dependency: Full EDR capabilities require Microsoft 365 E5, E5 Security or the standalone Defender for Endpoint Plan 2 licence. Organisations on Plan 1 or lower-tier bundles get reduced functionality
- Microsoft-centric assumptions: The platform works best in Microsoft environments. Organisations with significant non-Microsoft infrastructure may find integration gaps
- Alert volume: Without careful tuning, Defender for Endpoint can generate high volumes of informational and low-severity alerts that require analyst time to triage
- Limited network visibility: Endpoint-focused detection with limited native network traffic analysis
Best For
Organisations already invested in the Microsoft 365 E5 ecosystem that want EDR capabilities without additional licensing costs.
3. SentinelOne Singularity
Overview
SentinelOne Singularity is an AI-powered EDR platform known for its autonomous response capabilities. The platform can automatically detect, contain, and remediate threats on endpoints without human intervention, a capability SentinelOne calls "autonomous endpoint protection."
Detection Approach
SentinelOne uses a combination of static AI (pre-execution analysis of files), behavioural AI (runtime monitoring of process activity), and its Storyline technology that automatically correlates related events into a narrative timeline.
Key Strengths
- Autonomous response: SentinelOne documents that the platform can automatically isolate devices, kill malicious processes, and roll back changes to restore systems to a trusted state. This is valuable for organisations with limited SOC staffing
- Storyline technology: Automatic correlation of related events into a visual attack timeline significantly accelerates investigation
- Cross-platform coverage: Strong support for Windows, macOS, Linux, and Kubernetes workloads
- Competitive pricing: Generally priced competitively against CrowdStrike, with simpler tier structures
Key Limitations
- Limited network visibility: SentinelOne's strength is endpoint detection. Network-layer visibility requires the Singularity XDR platform with additional data connectors
- Cloud visibility gaps: While expanding, SentinelOne's cloud workload protection is less mature than its endpoint capabilities
- Autonomous response concerns: Fully automated remediation can occasionally take disruptive actions (such as quarantining legitimate files or terminating benign processes), requiring careful policy configuration
Best For
Organisations that prioritise automated response and want an EDR platform that can act autonomously, particularly those with lean security teams that cannot investigate every alert manually.
4. Palo Alto Cortex XDR
Overview
Palo Alto Networks' Cortex XDR connects data from endpoint, network, cloud, identity, and email sources to provide cross-domain detection and response. It integrates with Palo Alto's firewall and Prisma Cloud products, creating a unified security platform for organisations invested in the Palo Alto ecosystem.
Detection Approach
Cortex XDR uses behavioural analytics, machine learning, and correlation across endpoint, network, and cloud data sources. The platform's analytics engine stitches together alerts from multiple sources into incidents, reducing alert volume and providing contextual investigation views.
Key Strengths
- Cross-domain correlation: Native integration of endpoint, network (from Palo Alto firewalls), and cloud telemetry provides broader context than endpoint-only solutions
- Strong analytics engine: The incident-stitching capability effectively reduces alert fatigue by grouping related alerts into coherent incidents
- MITRE ATT&CK participation: Palo Alto Networks takes part in the public MITRE ATT&CK Evaluations; check the latest round for its current coverage
- Managed threat hunting: Palo Alto offers a managed service that combines Unit 42 threat intelligence with Cortex XDR analytics for organisations that want proactive threat detection support
Key Limitations
- Ecosystem lock-in: Cortex XDR delivers its full value when paired with Palo Alto firewalls and Prisma Cloud. Organisations using different firewall or cloud security vendors will not benefit from native network integration
- Complexity: The breadth of the Palo Alto platform can be complex to deploy and manage, particularly for smaller security teams
- Pricing: Palo Alto's licensing model can be opaque, and the full Cortex XDR platform with all capabilities is a premium investment
Best For
Organisations already invested in the Palo Alto Networks ecosystem (firewalls, Prisma) that want to extend detection across endpoint, network, and cloud within a single vendor's platform.
5. Elastic Security
Overview
Elastic Security, built on the Elasticsearch platform, unifies SIEM, XDR, endpoint security and cloud security in one product. Elastic documents that it can run on Elastic Cloud or on your own self-managed infrastructure, which gives it unique positioning for organisations that value transparency and customisation.
Detection Approach
Elastic Security uses a combination of signature-based detection, behavioural rules, machine-learning anomaly detection, and community-contributed detection rules. The Elastic Endpoint agent provides process monitoring, file integrity monitoring, and malware prevention.
Key Strengths
- Open and transparent: Detection rules are published openly on GitHub, allowing review, contribution, and customisation. This transparency builds trust and enables organisations to understand exactly what they are detecting
- Flexible deployment: Self-managed, cloud, or hybrid deployment options provide flexibility that few competitors match. Air-gapped environments are supported
- Combined SIEM and EDR: Elastic Security offers SIEM and EDR capabilities in a single platform, reducing tool count
- Cost-effective at scale: For organisations willing to self-manage, Elastic can be significantly more cost-effective than commercial alternatives
Key Limitations
- Significant tuning required: Elastic scored well in the 2024 protection test, but Elastic Security requires substantial tuning, custom rule development, and ongoing maintenance to get the most from its open rules in your estate
- Operational overhead: Self-managed deployments require expertise in Elasticsearch cluster management, index lifecycle policies, and performance tuning
- Team size requirements: Effective operation of Elastic Security requires skilled analysts and engineers, making it less suitable for lean teams
- Limited automated response: Response capabilities are less mature than CrowdStrike or SentinelOne, requiring more manual investigation effort
Best For
Organisations with mature security teams that value open-source transparency, deployment flexibility, and are willing to invest in customisation and tuning.
6. Sophos Endpoint (Intercept X)
Overview
Sophos Endpoint, long sold as Intercept X, is described by Sophos as a unified endpoint protection and EDR product. It protects Windows, macOS and Linux endpoints and servers from one agent, managed in Sophos's cloud console alongside the rest of the Sophos portfolio.
Detection Approach
Sophos leads with prevention. Its product page states that more than 60 proprietary exploit mitigations are on by default for every running process, that deep learning classifies malware before it runs, and that CryptoGuard watches file contents for malicious encryption and blocks the process responsible. Adaptive Attack Protection switches the endpoint into a more aggressive mode when it detects an active attacker.
Key Strengths
- Strong defaults: Sophos says strong protection is enabled by default, so teams without dedicated security staff get the strongest configuration without tuning
- Ransomware protection: CryptoGuard targets the encryption step itself, not only known ransomware files
- Managed option: Sophos MDR adds 24/7 threat detection, threat hunting and incident response as a service
- Tested: Intercept X Advanced scored 98.0% real-world protection and 97.1% malware protection with 2 false alarms in the AV-Comparatives 2024 business test
Key Limitations
- Pricing not published: The product page does not list prices, so compare quotes on the same scope
- Portfolio pull: Cross-product features work best with other Sophos controls, such as its firewalls
Best For
Small and mid-sized organisations that want strong protection out of the box and may add a managed service later.
7. TrendAI Vision One
Overview
Trend Micro now trades as TrendAI, and its platform is TrendAI Vision One Security Operations. It combines XDR with what TrendAI calls agentic SIEM and agentic SOAR, and lists native detection and response for endpoints, networks, identity, email, cloud workloads and data.
Detection Approach
Endpoint telemetry is one of six native sources. TrendAI states that the XDR layer unifies native and third-party telemetry in one console, and an AI Companion guides investigations and suggests next steps.
Key Strengths
- Breadth from one vendor: Endpoint, network, identity, email, cloud and data detection sit in one platform
- SIEM and SOAR included in the platform: Useful if you are consolidating a separate SIEM at the same time
- Deployment choices: The platform page lists sovereign and private cloud options
Key Limitations
- Scope to configure: A platform this broad takes planning to deploy well; scope the first phase to endpoints and one other source
- No result in the AV-Comparatives 2024 business test: Ask for current independent test results
- Pricing not published: The platform page gives no prices or pricing model
Best For
Organisations that want to buy EDR, XDR and SIEM from one vendor and have the staff to run a broad platform.
8. Bitdefender GravityZone
Overview
Bitdefender GravityZone deploys a single agent that provides endpoint protection and EDR on Windows workstations and servers, macOS and major Linux distributions. Bitdefender states that the cloud console needs no on-premises infrastructure, that an EU-hosted option exists for data sovereignty, and that an on-premises console is available.
Detection Approach
Bitdefender's EDR page describes prevention layers including patch management, exploit defence and fileless attack defence, then correlation of attacks across endpoints into one larger incident, with a graphical view of the attack chain and historical and live threat hunting.
Key Strengths
- Top protection scores: GravityZone Business Security Premium scored 99.8% real-world protection and 99.2% malware protection with 1 false alarm in the AV-Comparatives 2024 business test
- Hosting choice: Cloud, EU-hosted or on-premises consoles suit data-residency requirements
- Cross-endpoint incidents: Related alerts on different machines are grouped into one incident
- Trial: Bitdefender offers a free trial of Business Security Enterprise
Key Limitations
- Package choice matters: Bitdefender sells several packages, from Small Business to Enterprise; confirm which one includes EDR and the other features you need
- Pricing not published on the product pages: Request quotes for the same endpoint count and tier
Best For
European and UK buyers who want high protection scores and control over where the management console and data are hosted.
9. Cynet
Overview
Cynet sells one platform covering endpoint, identity, network, email, cloud and SaaS security, and mobile protection, with security automation (SOAR). Its CyOps team provides 24x7 managed detection and response as part of the offer. Cynet addresses its site to MSPs and SMEs as well as in-house IT and security teams.
Detection Approach
Cynet combines automated detection and response across its sources with human review by the CyOps team. It lists more than 80 built-in integrations for connecting existing tools.
Key Strengths
- Managed team included: 24x7 MDR from CyOps suits organisations with no in-house SOC
- One platform: EDR, XDR and SOAR are sold together, which keeps the tool count down
- MSP programme: Suited to organisations whose IT is run by a managed service provider
Key Limitations
- No result in the AV-Comparatives 2024 business test: Ask for current independent results
- Pricing not published on the platform page: Cynet sells in packages; compare quotes like for like
- SME focus: Larger enterprises should test how the platform and service scale to their estate
Best For
Small and mid-sized organisations, and the MSPs that serve them, that want EDR and a managed response team from one supplier.

How to choose an EDR solution
Work through these steps in order. Each one removes vendors from the list before you spend time on demos.
- Count your analysts and hours. Decide who will read alerts at 3am. If nobody will, shortlist vendors that include a managed service or automated containment.
- List the operating systems and servers you must cover, including Linux servers and cloud workloads. Drop any vendor that does not support them.
- Check independent results. Read the latest AV-Comparatives, SE Labs or MITRE ATT&CK Evaluations round for each vendor, and note which product was tested.
- Decide what else must be in scope. If investigations need network, identity or email data, compare the EDR tier with the XDR tier, or a unified platform, now, not after purchase.
- Price the full scope. Ask for a quote on the same device count, retention period and add-ons from each vendor. Add the cost of the SIEM and staff you will still need.
- Test in your environment. Run a proof of value on a representative set of devices alongside your current tool, and measure alert volume, not only detections.
- Confirm where data is held and under which jurisdiction (see the UK buying notes below).
The framework below helps with steps 1, 4 and 5.
Decision framework
The right EDR solution depends on your organisation's specific context. Use this decision framework to guide your evaluation:
By Team Size
- 1-3 analysts: Choose a platform with strong automation and low operational overhead. SentinelOne (automated containment and rollback) and vendors that include a managed service suit this. Avoid Elastic Security, which requires significant hands-on management.
- 4-10 analysts: Most platforms on this list will work. Prioritise detection accuracy and integration with your existing stack.
- 10+ analysts: Your team can handle more complex platforms. CrowdStrike, Cortex XDR, and Elastic Security become more viable when you have the staff to exploit their flexibility.
By Existing Stack
- Microsoft-centric: Microsoft Defender for Endpoint is the natural choice if you already have E5 licensing.
- Palo Alto firewalls: Cortex XDR provides native network integration that other EDR platforms cannot match within the Palo Alto ecosystem.
- No strong vendor commitment: Choose on test results, pricing model and the evidence your investigations need; CrowdStrike and SentinelOne both run without a wider vendor stack.
By Budget
- Budget-constrained: Microsoft Defender is already paid for if you hold E5. Otherwise price the full scope: a platform that also covers network and identity should be compared with your EDR plus the NDR and SIEM ingest it could replace, not with the EDR line alone.
- Flexible budget: CrowdStrike and SentinelOne provide strong standalone EDR at premium pricing.
By Compliance Requirements
- DORA, NIS2, FCA: Platforms that combine detection with a record of each response action reduce the reporting burden. Ask each vendor how alerts, actions and timelines are exported for an incident report.
By AI Exposure
- Copilots or agents already act on your endpoints: The EDR question becomes an evidence question. The CISO's AI Accountability Playbook sets out eleven checks for whether you could prove, stop and undo what one AI workflow did, and your EDR record is the first place an auditor will look.
UK buying notes
- Cyber Essentials. The NCSC's Cyber Essentials scheme has five technical controls, one of which is malware protection. Any EDR on this list meets that control when deployed and kept up to date across in-scope devices. Cyber Essentials Plus adds independent technical testing that the controls work, so make sure the EDR is on every device the assessor will sample.
- Data location. The NCSC's cloud security principle on asset protection says you should know where your data is and who can access it, and identify which legal jurisdictions it could be subject to. Ask each EDR vendor where telemetry is stored and processed, and whether a UK or EU region is available. Bitdefender, for example, offers an EU-hosted console and an on-premises console; Elastic can be self-managed.
- Logging and monitoring. NCSC device security guidance advises combining on-device logging with monitoring data from network-layer devices. An EDR covers the first; plan how you will cover the second.
- Regulation. For organisations in scope of NIS2 through EU operations, or of FCA and DORA requirements, ask how the EDR evidence (alerts, response actions, timelines) will be exported for incident reporting.
- Currency. Published list prices on this page are in US dollars on US pricing pages. Ask for a sterling quote and check whether VAT and support are included.
Frequently Asked Questions
What is the best EDR solution for mid-market organisations?
It depends on your analyst headcount and what you already own. Start with the false alarms your team can absorb and whether investigations need network and identity evidence as well as endpoint. Microsoft Defender for Endpoint is the natural choice if you already hold Microsoft 365 E5, and CrowdStrike and SentinelOne are strong choices for standalone EDR.
What is the difference between EDR and XDR?
EDR focuses specifically on monitoring and protecting endpoints. XDR (Extended Detection and Response) extends detection beyond endpoints to include network traffic, cloud workloads, email, and identity data. XDR platforms correlate signals across these multiple data sources to detect threats that would be invisible to endpoint-only solutions.
How much does EDR cost?
EDR pricing varies significantly by vendor and capability tier. Standalone EDR solutions typically charge per endpoint, with rates varying by feature tier. However, the true cost includes additional tools needed for full visibility (NDR, SIEM, SOAR), infrastructure costs, and the staff required to operate the platform. Compare quotes on the full stack you would need, not the EDR line alone.
Can EDR detect fileless malware?
Yes, modern EDR solutions can detect fileless malware through behavioural analysis rather than file-based scanning. Fileless attacks that use PowerShell, WMI, or legitimate system tools are detected by monitoring process behaviour, command-line arguments, and memory operations. Peer-reviewed work on living-off-the-land detection confirms why this is necessary: these attacks may create no malicious files on the victim machine, so anti-virus scans fail to detect them (Ongun et al., RAID, 2021).
Who are the main EDR vendors in 2026?
The main EDR vendors include CrowdStrike, Microsoft, SentinelOne, Palo Alto Networks, Elastic, Sophos, TrendAI (formerly Trend Micro), Bitdefender and Cynet. Other vendors tested by AV-Comparatives in 2024 include ESET, Kaspersky, Trellix, VIPRE, Cisco and VMware Carbon Black. Shortlist on independent test results, the pricing model and whether you need a managed service.
Do I still need a SIEM if I have EDR?
Traditional EDR solutions provide endpoint visibility only, so most organisations still deploy a SIEM for log aggregation, correlation across data sources, and compliance reporting. If you choose a standalone EDR, confirm how log aggregation, cross-source correlation, and compliance reporting will be covered, whether by that vendor's wider platform or by a SIEM you already run.
