Detect Fast, Respond Safely, Prove Everything
EDR / MDR / XDR is your stacked strategy for finding real threats quickly, stopping them safely, and shipping audit-ready evidence.
SolveForce designs, deploys, and operates these capabilities so they work together—with identity, network, cloud, and data controls—under a Zero-Trust model.
Where this lives in the SolveForce system:
🔒 Security (Semantics) → Cybersecurity • 📊 Analytics/Automation → SIEM / SOAR
🔑 Identity & Access → IAM / SSO / MFA • 🔐 ZTNA/SASE → ZTNA • SASE
🖧 East–West → NDR • ☁️ Cloud → Cloud • 🛠️ Ops → Patch Management • NOC Services
🎯 What Each Piece Means (Clear and Practical)
- EDR — Endpoint Detection & ResponseAgent on endpoints/servers that collects process, script, file, registry, and network telemetry; raises detections; enables isolate/kill/quarantine and forensic collection.
→ Deep dive: EDR (endpoint-focused page) - MDR — Managed Detection & Response24×7 service operating on top of EDR/XDR + SIEM/SOAR to triage, investigate, and contain incidents—then report with executive evidence.
→ Details: MDR - XDR — Extended Detection & ResponseCorrelates endpoint + network + identity + email/web + cloud signals, reduces noise, and coordinates response across domains via SOAR.
→ Details: XDR
Quick rule: Start with EDR for host truth, add MDR for 24×7 response, lift to XDR to cut false positives and contain across identity/network/cloud.
🧱 Architecture (Four Layers Working Together)
1) Collect & Normalize – EDR agents, NDR sensors, IdP/SSO logs, email/web gateways, cloud control-plane, app/API logs → normalized schema.
2) Detect & Correlate – rules, sequences, baselines (UEBA), intel → high-confidence alerts (XDR).
3) Decide – risk policy + approvals: contain now, step-up MFA, quarantine, rotate secrets, or escalate.
4) Act & Prove – SOAR runs playbooks (isolate host, block domain/IP, NAC quarantine, SD-WAN pin, ZTNA revoke), then writes back evidence to SIEM and cases.

🔍 Telemetry We Use (and Why)
- Endpoints (EDR) — process trees, command lines, script telemetry, kernel/file events, persistence; fastest host truth.
- Network (NDR) — east–west + egress (DNS, TLS SNI/JA3, flows/PCAP metadata); finds lateral movement/beacons/exfil where agents can’t run. → NDR
- Identity — IdP sign-ins (SAML/OIDC), MFA outcomes, privilege changes; detects account takeover early. → IAM / SSO / MFA
- Email/Web — phishing/BEC verdicts, sandbox results, SWG/CASB; stops the front-door. → SASE • WAF / Bot Management
- Cloud/Kubernetes — CloudTrail/Activity logs, API abuse, storage/object moves, k8s audit; closes cloud blind spots. → Cloud
- Data Security — DLP events, watermark/read-only actions; proves containment of sensitive data. → DLP
🚨 High-Value Detections (ATT&CK-Aligned)
- Ransomware Behavior— rapid file encryption + shadow-copy tamper + suspicious parent tree → isolate host, kill process, hash block, restore path.
- C2 + Credential Misuse— periodic beacons + Kerberos anomalies/SSO token abuse → isolate, revoke sessions, rotate secrets (PAM). → PAM
- Lateral Movement— SMB enum/RDP valid + new service/SchTasks + admin group add → NAC quarantine, kill process, notify IAM. → NAC
- Data Exfil— big egress to new ASN/cloud bucket + DLP hits + odd time/geo → block egress, lock account, open IR case. → Incident Response
- BEC (Business Email Compromise)— inbox rule + lookalike domain + impossible travel → token revoke, tenant purge, finance alert.
🧰 Orchestrated Response (Safe by Design)
- Endpoints — isolate host; kill/quarantine file/process; take triage bundle. → EDR
- Network — FW/WAF rule push, NAC quarantine, SD-WAN path pin/blackhole, Anycast withdraw. → NAC • SD-WAN • WAF / Bot Management
- Identity — session revoke, step-up MFA, account lock, PAM rotate. → IAM / SSO / MFA • PAM
- Cloud/SaaS — disable keys, freeze buckets, snapshot disks, CASB session control. → Cloud • SASE
- Data — quarantine object, watermark, route to tokenization. → DLP
Safety rails: human approvals for destructive steps, simulation/dry-run, blast-radius caps, automatic rollback/circuit-breaker, change IDs via ITSM.
📐 SLO Guardrails (Experience & Fidelity You Can Prove)
| Metric | Target (Sev-1) | Notes |
|---|---|---|
| Mean Time To Detect (MTTD) | ≤ 5 min | XDR correlation + tuned rules |
| Mean Time To Contain (MTTC) | ≤ 15–30 min | SOAR playbooks + approvals |
| EDR Agent Coverage | ≥ 98–99% | Exceptions documented & risked |
| Alert Precision (priority rules) | ≥ 92–95% | After weekly tuning |
| False-Positive Rate | ≤ 5–8% | Track per use case |
| Evidence Completeness (Sev-1/2) | 100% | Timeline + artifacts + actions |
Dashboards live in SIEM/SOAR and the NOC; monthly reports track MTTD/MTTR, precision/recall, auto-contain %, and noise reduction.

🧪 Tuning & Noise Reduction (Weekly Loop)
1) Review false positives/negatives; adjust sequences, intel, thresholds; retire noisy rules.
2) Promote successful hunts to rules; remove rules that never fire.
3) Validate ingestion lag and parser health (schema drift = bad detections).
4) AIOps to dedupe flaps and correlate multi-signal incidents. → NOC Services
☁️ Cloud & Hybrid Patterns (Real-World Starting Points)
- EDR → XDR Start— keep your EDR; add identity + NDR + email + cloud to raise fidelity quickly. → NDR
- Colo Hub + On-Ramps— put detection close to Direct Connect/ExpressRoute/Interconnect; deterministic paths for crown-jewel apps. → Direct Connect • Colocation
- Remote/OT/IoT— where agents can’t run, rely on NDR, NAC, and ZTNA to detect/contain. → NAC • ZTNA
🔒 Zero-Trust Interlock (Identity → Device → Network → Data)
- Identity — SSO/MFA, adaptive risk, step-up for admin actions. → IAM / SSO / MFA
- Device — UEM posture gates access; non-compliant devices quarantined. → MDM / UEM
- Network — micro-isolation with NAC/SD-WAN/SASE; Anycast withdraw for sick POPs. → SASE
- Data — DLP rules, tokenization, and watermarks enforced inline. → DLP
🧾 Reporting, Evidence & Compliance
- Cases— alert → triage → actions → closure with artifacts (PCAPs/hashes/logs), owners, approvals, RCAs.
- Executive IR— scope, dwell time, impacted assets, controls added; share with audit.
- Mappings— PCI DSS, HIPAA, ISO 27001, NIST 800-53/171, CMMC; exportable evidence packs.
All events flow to SIEM; actions executed via SOAR with immutability options for retention. → SIEM / SOAR
🧰 Implementation Blueprint (No-Surprise Rollout)
- Source inventory — EDR, NDR, IdP, email/web, cloud, FW/WAF, DLP, ticketing.
- Schemas & parsers — normalized fields (host/user/src/dst/action/severity/labels).
- Priority use cases — ransomware, ATO/BEC, exfil, lateral movement; set precision/recall targets.
- Playbooks & approvals — isolate/kill/block/revoke/rotate/snapshot; blast-radius caps; rollback.
- SLOs & dashboards — MTTD/MTTR, precision/recall, coverage %, ingestion lag.
- Drills — quarantine VLAN, token revoke, WAF virtual patch, sinkhole; record RCAs. → Tabletop Exercises
- Operate & tune — weekly loop; publish wins and next steps.
💵 Commercials (What Drives Cost)

Key terms in plain language
Open a term for a concise explanation of language used on this page.
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.
Software as a Service (SaaS)
Software accessed as an online service instead of being installed and maintained entirely on the customer’s own computers or servers.
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.
