Managed EDR Service: Keep Your Existing Endpoint Platform

Your endpoint platform is generating alerts. The question is whether anyone is watching them at 2 AM on a Saturday. Precursor Security's managed EDR service layers 24/7 UK SOC monitoring, threat hunting, and active incident response on top of your existing CrowdStrike, Defender, or Carbon Black deployment, without requiring a platform change. Keep your licenses, your tuning, and your configuration. Add the human layer. Part of our full MDR service.

BYOE MDR

Your EDR Investment. Our Analyst Team.

Most vendor-managed EDR services require you to abandon your existing platform. Precursor operates a 24/7 UK SOC that plugs into your current CrowdStrike, Defender, or Carbon Black deployment via API. Keep the licenses you have paid for, the tuning your team has built, and the configuration that fits your environment. We add the analyst layer that makes it all work around the clock.

Engagement Pipeline

Engagement Workflow

Structured to minimise operational friction and maximise the value of the testing window.

Step 01

EDR API Integration and Baseline

We connect to your endpoint platform via read-only API and establish a baseline of normal telemetry across your environment. Alert tuning begins immediately to reduce false positives and align detection thresholds with your risk profile. Existing suppression rules and custom detection policies are preserved. We build on the tuning your team has invested in, not overwrite it.

Step 02

SOC Onboarding and Alert Routing

EDR alerts route directly into our UK-based Security Operations Centre. Analysts receive contextual briefings covering your critical assets, business hours, approved software baselines, and escalation contacts. RBAC configuration maps your internal approval workflow. Tier 1 triage begins immediately, with Tier 2 analysts handling investigation and escalation.

Step 03

24/7 Monitoring and Threat Hunting

Continuous managed EDR monitoring goes live. Threat hunters proactively query endpoint telemetry for indicators of compromise, anomalous process execution, and living-off-the-land techniques. Detection rules are updated against the MITRE ATT&CK framework as new TTPs emerge. CrowdStrike environments receive Falcon Insight telemetry correlation against our threat intelligence feeds.

Step 04

Incident Response and Board Reporting

Confirmed threats trigger immediate containment: endpoint isolation, process termination, and designated contact notification via phone, email, or Slack within your agreed SLA. Monthly reporting covers mean time to detect, mean time to respond, incident volume, and root cause analysis. Reports are structured for board-level and audit review, with compliance mapping to Cyber Essentials and ISO 27001.

Procurement Requirements

Fixed monthly pricing with no per-incident fees. No hardware procurement. No multi-year lock-in. All monitoring, triage, and incident response is performed by CREST-certified, UK-based analysts in our Newcastle SOC. Endpoint telemetry never leaves the UK.

Detection Coverage

Managed EDR Integration
Methodology

We enhance your existing EDR with human-led managed detection and response: proactive hunting, rapid incident containment, and continuous tuning, adding the 24/7 analyst layer your platform generates alerts for but cannot act on alone.

Integration

Multi-Vendor EDR Support

We integrate with CrowdStrike Falcon, Microsoft Defender, Carbon Black, Trellix, SentinelOne, and other major EDR platforms via API. No rip-and-replace of your existing investment. Managed EDR monitoring begins without disrupting your existing configuration or tuning work.

SOC Operations

24/7 UK-Based SOC Monitoring

Your EDR alerts are triaged by analysts in our physical UK Security Operations Centre (Newcastle). Every alert that fires overnight, on weekends, or over public holidays receives the same response as one raised at 9 AM on a Tuesday. We separate real threats from false positives and respond to genuine incidents within minutes, not hours.

Threat Hunting

Threat Hunting and Tuning

Proactive managed endpoint detection and response goes beyond passive alert monitoring. Our threat hunters query EDR telemetry for Indicators of Compromise, anomalous process execution, and living-off-the-land techniques. We continuously tune detection rules to reduce false positive noise and improve alert fidelity, building on tuning your team has already done.

Response

Incident Response Playbooks

Pre-defined playbooks for ransomware, lateral movement, credential theft, and data exfiltration. When a CrowdStrike MDR alert fires or any supported platform detects a genuine threat, our analysts execute containment steps immediately: isolating endpoints, terminating processes, blocking C2 traffic. Pre-approved actions execute without requiring your sign-off at 2 AM.

Correlation

Unified Visibility Dashboard

Single-pane-of-glass view combining EDR alerts with network, cloud, and identity telemetry. Cross-correlate endpoint events with firewall logs, Azure AD sign-ins, and email security alerts to detect multi-stage attacks that single-vendor managed detection and response services miss.

Closed-Loop Security

The Closed-Loop
Approach.

EDR monitoring works best when paired with offensive security validation and full-spectrum MDR coverage. Our penetration testers use SOC threat intelligence to simulate attacks against your endpoint controls, confirming that your EDR catches real adversary techniques.

Managed EDR Service: Common Questions

Pricing, platforms, onboarding, and how BYOE MDR compares to vendor-managed alternatives.

Managed EDR service pricing typically ranges from £900+ per month depending on endpoint count and integration complexity. Small organisations (up to 250 endpoints) average £900+/month for 24/7 monitoring, threat hunting, and incident response. Mid-sized organisations (250-1,000 endpoints) typically cost £2,500-£4,000/month. Large enterprises (1,000+ endpoints, multiple EDR consoles) typically cost £4,000-£5,000+/month. Because you retain your existing EDR licenses, you pay only for the SOC service, not a replacement platform. We provide fixed monthly quotes within 48 hours of understanding your endpoint count and EDR platform. For a managed EDR pricing estimate for your specific endpoint count, contact us and we will provide a fixed monthly quote within 48 hours.

Bring Your Own EDR (BYOE) means we provide Managed Detection and Response (MDR) services using your existing endpoint security platform: CrowdStrike, Microsoft Defender, Carbon Black, and others. You keep your current EDR license and deployment; we add 24/7 SOC monitoring, threat hunting, and incident response capabilities on top of it. EDR is the alarm system. Managed EDR is the alarm system plus the security team who monitors it 24/7 and acts when it goes off.

EDR (endpoint detection and response) is a software platform (CrowdStrike, Defender, SentinelOne) that runs on your endpoints and generates security alerts. Managed EDR is a service where a security team monitors those alerts 24/7, triages real threats from false positives, and takes response actions when needed. MDR (managed detection and response) is a broader term for the same type of service, typically covering more than just endpoints, adding network, cloud, and identity monitoring. On this page, managed EDR and MDR are used interchangeably to describe a service that adds 24/7 human-led monitoring to your existing EDR platform.

The primary benefits are: (1) 24/7 coverage your internal team cannot sustain without significant additional headcount; (2) faster response: a trained analyst who acts on an alert at 2 AM, not 9 AM the next working day; (3) alert fatigue reduction through continuous tuning and false positive suppression; (4) active incident containment: isolating endpoints, blocking C2 traffic, not just sending email notifications; (5) compliance evidence for cyber insurers, DORA, NIS2, and Cyber Essentials Plus auditors. For most mid-market organisations, the cost of managed EDR is between one-quarter and one-sixth the cost of hiring equivalent in-house SOC analysts.

Falcon Complete is CrowdStrike's own managed service and covers only CrowdStrike endpoints. It cannot monitor your Defender, SentinelOne, or other security tools. It is also typically priced for enterprise scale. Our managed EDR service works with CrowdStrike Falcon (and five other major EDR platforms), adds cross-tool correlation across network, cloud, and identity data, and is priced from £900/month for organisations who already hold their own CrowdStrike license. You keep the Falcon investment and the tuning you have already done. We add the 24/7 monitoring layer. Our service also includes managed SentinelOne EDR and other platforms through the same fixed-fee model.

We support CrowdStrike Falcon, Microsoft Defender for Endpoint, VMware Carbon Black, Trellix (McAfee) ENS, SentinelOne, Palo Alto Cortex XDR, Trend Micro, and others. If your EDR has an API or SIEM integration capability, we can monitor it. For organisations running SentinelOne, see our dedicated managed SentinelOne EDR service.

Initially, we require read-only API access to ingest alerts and telemetry. For incident response capabilities (endpoint isolation, process termination), we need elevated permissions, but these are scoped to specific response actions and can be restricted via role-based access controls. We walk through RBAC configuration during onboarding to ensure your team retains full visibility and control.

Yes. One of the first tasks during onboarding is reviewing your existing EDR detection policies. We review your alert volume, suppress benign triggers (for example, approved admin tools flagged as threats), and fine-tune sensitivity based on your risk tolerance and operational context. We inherit your existing suppression rules and continue the tuning work your team has already started.

When our SOC confirms a genuine threat, we immediately notify your designated contacts via phone, email, or Slack. We execute pre-approved containment actions (isolating the endpoint, blocking C2 domains) and provide a detailed incident timeline with evidence and remediation recommendations. Monthly reports include full root cause analysis and MTTD/MTTR metrics.

Typically yes. 12 months is standard for MDR services. This allows us to properly baseline your environment, tune detection rules, and demonstrate measurable security improvements. Fixed monthly pricing means no per-endpoint overages or surprise charges when we respond to an incident.
