Endpoint Detection & Response (with MDR & XDR Options)
Endpoint Detection & Response (EDR) continuously monitors laptops, desktops, servers, and VDI to detect, investigate, and contain threats in real time. SolveForce designs EDR as part of a Zero-Trust stack—integrated with identity, device posture, network controls, and orchestration—so incidents are found fast, stopped safely, and documented for audits.
Where EDR fits in the SolveForce model:
🔒 Security (Semantics) → Cybersecurity • 👤 Identity → IAM / SSO / MFA
📱 Device Trust → MDM / UEM • 🌐 Access → ZTNA / SASE
📊 Analytics & Automation → SIEM / SOAR • 🖧 East-West → NDR
🔄 Ops → Patch Management • NOC Services
🎯 Outcomes (What a strong EDR program delivers)
- Rapid detectionof malware, fileless attacks, and suspicious behaviors.
- Containment in minutes(isolate host, kill process, block hash/domain).
- End-to-end evidence(timeline, artifacts, and actions) for IR and audits.
- Lower MTTRvia automated SOAR playbooks and clear runbooks.
- Zero-Trust alignmentwith identity, device posture, and network policy.
🧭 EDR vs. MDR vs. XDR (Spelled out)
| Term | What it means | When to choose |
|---|---|---|
| EDR — Endpoint Detection & Response | Agent on endpoints collects telemetry (processes, modules, registry, network), detects threats, and enables remote response. | You have a security team running detections and response. |
| MDR — Managed Detection & Response | A provider operates 24×7 monitoring, triage, and response on top of your EDR. | You need round-the-clock eyes and expertise. |
| XDR — Extended Detection & Response | Correlates endpoint with email, identity, network, cloud telemetry for higher-fidelity detections. | You want fewer false positives and cross-domain visibility. |
SolveForce can implement EDR-only, EDR + MDR, or XDR depending on your team and scope.
🧱 Core EDR Capabilities
- Behavior analytics— process trees, script/PowerShell logging, LOLBins detection, in-memory indicators.
- Ransomware prevention— suspicious encryption patterns, shadow-copy tamper alerts, rapid isolate.
- Threat intel & hash control— blocklists/allowlists, suspicious publisher detection.
- Response actions— isolate endpoint, kill/quarantine, registry/file rollback (where supported), collect triage package.
- Hunt & query— fleet-wide queries (e.g., “who has
xyz.dllloaded?”), scheduled hunts with saved results. - Forensics— timeline, artifacts, persistence keys, network beacons, exfil domains.
🔒 Zero-Trust Interlock (Identity → Device → Network → Data)
- Identity: require SSO/MFA for console access; role-based least privilege. → IAM / SSO / MFA
- Device: MDM/UEM posture gates access (encryption on, EDR healthy, OS version). Non-compliant → quarantine. → MDM / UEM
- Network: isolate host, apply microseg rules, or route through ZTNA/SASE for inspection. → ZTNA • SASE
- Data: invoke DLP for suspected exfil; watermark or block uploads. → DLP
🧩 Telemetry & Detection Sources
- Process & script telemetry(command lines, parent/child relations, AMSI where supported).
- Kernel/driver events(file, registry, handle operations).
- Network events(destinations, DNS, TLS SNI, certificate metadata).
- Persistence & autoruns(services, tasks, WMI, Run keys).
- User/identity signals(logon type, token operations, privilege escalations).
- Threat intel(hash/domain/IP feeds; sandbox verdicts).
Correlate with NDR (Network Detection & Response) for east-west visibility and exfil. → NDR
🚨 Response Playbooks (Concrete, repeatable)
Sev-1: Active ransomware behavior
1) Isolate host from network.
2) Kill offending process; revoke tokens; disable scheduled tasks.
3) Block hash/domain; snapshot/dump forensics.
4) Halt propagation via NAC/SD-WAN policy; force reauth via IAM. → NAC • SD-WAN
5) Recover files (restore points/immutable backup). → Backup Immutability
Sev-2: Suspected credential theft (infostealer/DCOM abuse)
1) Expire sessions; force MFA for impacted identities. → IAM / SSO / MFA
2) Rotate secrets (PAM for privileged). → PAM
3) Hunt for lateral movement; tighten ZTNA groups. → ZTNA
Sev-3: PUA/Adware
1) Remove; 2) Add to blocklist; 3) Ticket for user coaching; 4) Close.
All playbooks run via SOAR (Security Orchestration, Automation & Response) to cut MTTR. → SIEM / SOAR
🧰 Deployment Patterns (OS & fleet realities)
- Windows— kernel/ETW visibility; AMSI; script block logging.
- macOS— system extensions; full disk access consent; notarized builds.
- Linux— eBPF/auditd/Kprobe visibility; container/daemon sets for servers.
- VDI/DAAS— persistent vs non-persistent images; update via golden image + post-login health.
- Servers— exclusion tuning for DB/backup paths; low-impact modes for latency-sensitive hosts.
🧪 Tuning & Noise Reduction (Keep signal high)
- Golden exclusionsfor backup paths, hypervisors, DB stores—documented and reviewed.
- Behavior-first rules(avoid pure hash firehose); use ATT&CK-mapped detections.
- AIOpsin the NOC to dedupe flaps and correlate multi-signal incidents. → NOC Services
- Hunt calendar(weekly scheduled queries); retire detections that never fire or always false-positive.
📐 SLO Guardrails (Experience & speed you can prove)
| Metric | Target (Recommended) | Notes |
|---|---|---|
| Mean Time To Detect (MTTD) | ≤ 5 minutes for Sev-1 | With high-fidelity rules/SOAR |
| Mean Time To Contain (MTTC) | ≤ 15 minutes Sev-1 | Auto-isolation + kill + block |
| Agent coverage | ≥ 98–99% endpoints | Exceptions documented & risked |
| False Positive Rate | ≤ 5% of total alerts | Weekly tuning loop |
| CPU/Memory overhead | ≤ 3–8% / ≤ 300–500 MB | Per vendor/feature set |
| Evidence completeness | 100% of Sev-1/2 with timeline & artifacts | IR/audit-ready |
Dashboards live in SIEM, EDR console, and NOC views; weekly reports summarize trends and actions.
🔒 Compliance Mapping (examples)
- PCI DSS— malware detection, file-integrity monitoring, least privilege, log retention.
- HIPAA— audit controls, integrity, person/entity authentication.
- ISO 27001— A.8, A.12 (ops security), A.16 (incident mgmt).
- NIST 800-53/171— SI/CM/IR families; endpoint content and incident handling.
- CMMC— detection & incident response maturity.
Evidence streams to SIEM/SOAR with incident IDs, actions, and approvals.
✅ Pre-Engagement Checklist
- Fleet inventory— OS mix, VDI, server roles, privileged endpoints.
- Use-case priorities— ransomware stop, lateral-movement detection, PII/PHI protection.
- Integrations— IdP/SSO, MDM/UEM, NAC/SD-WAN, SIEM/SOAR, ticketing.
- Playbooks— isolate, kill, block, secrets rotate, restore, reauth, notify.
- Exclusions— DB/backup/AV paths; high-IO workloads.
- SLOs— MTTD/MTTC, coverage %, FP rate, performance caps, reporting cadence.

Key terms in plain language
Open a term for a concise explanation of language used on this page.
Latency
The time it takes data to travel between two points. Lower latency improves voice, video meetings, cloud applications, gaming, and other real-time services.
SD-WAN
Software-defined wide area networking. It manages multiple connections and chooses paths based on application needs, performance, and policy to improve resilience and control.
Cybersecurity
The practices and controls used to protect identities, devices, networks, applications, and data from unauthorized access, disruption, or manipulation.
Zero Trust
A security model that does not automatically trust a user or device because of its location. Access is continuously verified and limited to what is necessary.
SASE
Secure Access Service Edge combines networking and security capabilities in a cloud-delivered architecture so users and locations can receive consistent policy wherever they connect.
Identity and Access Management (IAM)
The systems and policies that determine who a user is, what resources they may access, and how that access is authenticated and reviewed.
Multi-Factor Authentication (MFA)
A login control requiring more than one form of verification, such as a password plus an authenticator app, security key, or biometric factor.
MDR / XDR
Security services and tools that monitor activity, investigate suspicious behavior, and help contain threats. MDR is managed detection and response; XDR correlates signals across multiple security layers.
