Managed Endpoint Detection and Response (EDR)
Detect malicious behaviour on laptops, workstations and servers—and contain it before one compromised host becomes a wider incident. CACI’s managed EDR service combines 24/7 monitoring, endpoint telemetry, expert investigation, threat hunting and authorised response actions.
Managed EDR for continuous endpoint protection
CACI maintains EDR coverage across eligible laptops, desktops, virtual endpoints and servers. We manage sensor deployment, policies, agent versions, telemetry health and exclusions across supported Windows, macOS and Linux systems.
Behavioural analytics assess process trees, command lines, scripts, file and registry changes, network connections, user context, indicators of compromise and indicators of attack. This helps expose ransomware, credential theft, persistence, lateral movement and fileless techniques.
Analysts validate detections, investigate root cause, hunt for related behaviour and preserve evidence. Agreed actions can include host isolation, process termination, file quarantine, forensic collection and indicator blocking.
What CACI’s managed EDR service includes
Endpoint discovery, deployment and migration
We assess eligible laptops, desktops and servers; operating-system support; existing antivirus or EDR controls; deployment tooling; exclusions; and business-critical workloads. Rollout is phased and validated before legacy controls are removed.
Sensor health and coverage management
Coverage dashboards identify missing, degraded or outdated sensors and endpoints that have stopped reporting. Exceptions are tracked to an owner so endpoint visibility does not erode after deployment.
Behavioural detection and alert validation
Endpoint telemetry is analysed for suspicious process chains, script execution, persistence, credential access, privilege escalation, defence evasion and lateral-movement indicators. Analysts validate evidence and business context before creating a high-priority incident.
Endpoint investigation and threat hunting
Investigations use process trees, command lines, file hashes, network connections, user context and historical telemetry to establish scope and root cause. Proactive hunts look for relevant behaviours across the protected estate.
Authorised endpoint containment
Agreed playbooks may include isolating a host, terminating a malicious process, quarantining a file or blocking an indicator. Response rights, customer approvals, exclusions and restoration steps are documented before go-live.
Policy, exclusions and platform optimisation
Detection policies, prevention settings and exclusions are reviewed through controlled change. Exceptions are time-bound and risk-owned where possible, reducing the chance that performance workarounds become permanent security gaps.
EDR platforms and endpoint integrations
CACI can work with an existing endpoint platform or support a controlled migration. Compatibility, licences, response permissions and data residency are confirmed before deployment.
Approved EDR and XDR platforms
CACI deploys and manages Microsoft Defender for Endpoint, CrowdStrike Falcon, SentinelOne Singularity, Palo Alto Cortex XDR, Sophos or Fortinet before publication.
Endpoint and workload coverage
Protect eligible Windows, macOS and Linux laptops, desktops, virtual endpoints, servers and supported cloud workloads, with platform-specific operating-system and feature limitations documented.
SIEM and SOC integration
Forward endpoint telemetry and validated incidents to approved SIEM, XDR, SOAR and case-management platforms so endpoint findings can support wider investigation and coordinated response.
How CACI implements and manages EDR
Our structured approach keeps visibility strong across endpoint security risks.
1. Assess and plan
We define eligible endpoints, operating systems, critical workloads, deployment methods, existing controls, exclusions and response constraints, producing a coverage baseline and rollout plan.
2. Pilot, deploy and transition
A representative pilot tests performance, compatibility, detections and response. Agents and policies then roll out in controlled waves before legacy controls are retired.
3. Monitor and improve
Analysts validate alerts, hunt for related behaviour and execute authorised actions. Reviews cover sensor health, recurring detections, exclusions, response outcomes and policy improvements.
Threats and behaviours managed EDR can uncover
- Ransomware behaviour and mass file modification
- Malware, malicious scripts and suspicious child processes
- Credential dumping and privilege escalation
- Persistence mechanisms and defence evasion
- Command-and-control activity and lateral movement
- Fileless and living-off-the-land techniques
Business outcomes of Managed Endpoint Detection and Response
Organisations adopting CACI Managed Endpoint Detection and Response services benefit from:
- Improved visibility across endpoint activity and security events
- Faster detection of ransomware, malware and advanced threats
- Reduced response times to security incidents
- Reduced alert fatigue for security teams
- Improved protection for remote and hybrid workforces
- Stronger endpoint security posture across the organisation
Use cases for managed endpoint detection and response
Protecting remote and hybrid workforces
Managed EDR services provide continuous visibility across laptops, desktops and servers regardless of location, helping organisations secure endpoints beyond the traditional corporate network.
Detecting and responding to ransomware threats
Behaviour-based analytics can identify ransomware activity, malicious scripts and suspicious process execution. Authorised response actions such as host isolation and file quarantine can help contain threats before they spread.
Replacing or enhancing traditional antivirus
Many organisations adopt managed EDR to improve visibility beyond signature-based antivirus technologies. Platforms such as Microsoft Defender for Endpoint, CrowdStrike Falcon and SentinelOne provide richer endpoint telemetry and investigation capabilities.
Strengthening endpoint protection without a dedicated SOC
Managed EDR services give organisations access to endpoint monitoring, threat hunting and incident investigation capabilities without needing to build a full Security Operations Centre.

Managed EDR, XDR or MDR?
Managed EDR is endpoint-focused: it protects and investigates laptops, workstations and servers using endpoint telemetry and response actions.
XDR correlates signals across additional domains such as identity, email, cloud and network. MDR is a managed outcome that combines technology with analysts and response; its telemetry scope varies by provider. Choose this service when endpoint coverage and host-level response are the primary requirement.
Choose Managed SOC Services when you need a broader cross-tool security operating model.

FAQs
Answers to common questions about managed endpoint and response.
Managed endpoint detection and response deploys and operates EDR across eligible endpoints. It monitors telemetry, validates detections, investigates suspicious behaviour, hunts for threats and performs agreed host-level actions. CACI’s scope should name supported platforms, coverage hours, operating systems and response authority.
Traditional antivirus mainly blocks known malicious files using signatures and prevention rules. EDR continuously records and analyses endpoint behaviour, helping detect suspicious activity that may use legitimate tools or previously unseen techniques. EDR also supports investigation, threat hunting and response actions such as host isolation.
EDR is the endpoint technology and telemetry layer. XDR correlates detections across multiple domains such as endpoint, identity, email, cloud and network. MDR is a managed detection-and-response service delivered by analysts; it may use EDR, XDR and other tools. Always confirm the telemetry and response scope.
Coverage commonly includes supported Windows, macOS and Linux laptops, desktops and servers. Exact support depends on the chosen EDR platform, operating-system versions, virtual desktop design, cloud workloads and specialist systems. Eligibility and exceptions should be documented during discovery.
EDR can detect behaviours associated with ransomware and may block processes, quarantine files or isolate hosts. No control guarantees prevention of every attack. Effectiveness depends on healthy coverage, policy configuration, timely investigation, response authority, identity security, patching, backups and tested recovery.
Typical actions include isolating a host from the network, terminating a process, quarantining a file, collecting forensic artefacts and blocking a hash or indicator. The contract and playbooks should state which actions are pre-authorised, which need approval and which systems are excluded.
Many EDR platforms include preventive anti-malware capabilities, but replacement should follow compatibility testing, a representative pilot, staged deployment and verified sensor health. Running two endpoint security agents together can cause performance or compatibility problems, so coexistence must be planned.
Pricing is commonly influenced by endpoint or server count, platform licensing, operating-system mix, coverage hours, investigation and threat-hunting scope, retention, response authority and onboarding or migration effort. Confirm how inactive devices, servers, cloud workloads and growth are counted.
Useful measures include healthy sensor coverage across eligible endpoints, outdated-agent rate, time to validate high-severity alerts, time to approved containment, recurring detection trends, exception ageing and completion of investigation or remediation actions.
