Managed Detection & Response (MDR)
Round-the-clock detection from a dedicated security operations center, tuned to your stack and wired into the compliance program that has to consume it -- with IR playbooks written before you need them.
Always-On Detection, Run as Part of Your Compliance Program
Continuous detection and triage run on Sophos MDR, a security operations center that does nothing else and is staffed around the clock. We do not ask you to believe a boutique firm replicates that in-house. What a platform cannot do is know your environment -- and that is the half most MDR purchases get wrong, ending as a license and a portal nobody opens. Jacobian is the bridge: we scope the deployment, tune detections to your application stack, and fold in the cloud-native signal from AWS GuardDuty, Security Hub, and Inspector alongside your SIEM (Splunk, Datadog Cloud SIEM, or Elastic).
Escalation reaches the team that already operates your infrastructure, through the PagerDuty rotation you already use rather than a vendor ticket queue you have to chase. Playbooks are written before the engagement starts: AWS account isolation, IAM credential rotation, endpoint quarantine, and forensic timeline reconstruction from CloudTrail, VPC Flow Logs, and application audit logs. Where an incident needs to withstand legal or regulatory scrutiny, the same team performs chain-of-custody forensic investigation.
Threat hunting runs on a quarterly cadence using MITRE ATT&CK as the framework. We hypothesis-test against your threat model, validate detection coverage gaps, and tune rules. Because Jacobian's roots are in audit and compliance work, every detection event is captured as evidence in the SOC 2 control library -- so the spend on detection also does work at audit time, and the auditor does not need a separate evidence package for monitoring.
Why Choose Our Managed Detection & Response (MDR)
Engineering rigor, audit-ready process, and operational depth across cloud, SaaS, and software delivery
Round-the-Clock Detection
Sophos's security operations center watches continuously; we decide what it watches -- GuardDuty, Security Hub, and SIEM rules tuned to your application stack rather than a generic ruleset.
Integrated Incident Response
Response playbooks pre-written for AWS account isolation, IAM rotation, EDR endpoint quarantine, and forensic timeline reconstruction. Wired into your existing PagerDuty rotation.
Threat Hunting
Quarterly hypothesis-driven hunts against MITRE ATT&CK with documented coverage analysis and detection-rule tuning. You see the coverage analysis, not just an alert count.
Audit-Ready Evidence
Every detection event lands in the SOC 2 / HIPAA evidence library automatically. SIEM logs retained per regulatory requirement (1+ year HIPAA, 12 months SOC 2 minimum).
Our MDR Onboarding Process
From kickoff to full coverage in 30 days
Threat Model & Coverage Assessment
Two-week assessment of your AWS account, application telemetry, EDR coverage, and existing detection capabilities. Output: a threat model mapped to MITRE ATT&CK with gap analysis.
SIEM & EDR Deployment
Days 8-21: deploy or tune your SIEM (Datadog Cloud SIEM, Splunk, or Elastic), GuardDuty, Security Hub, Inspector. Connect EDR (Sophos Intercept X, or the CrowdStrike, SentinelOne, or Defender deployment you already run). Wire alerts into PagerDuty.
Detection Rule Library
Days 14-30: write and tune detection rules specific to your stack. Test through purple-team exercises before going live. Document each rule's MITRE technique mapping and expected false-positive rate.
Steady-State Operations
Day 30+: full coverage live. Monthly tuning reviews, quarterly threat hunts, semi-annual purple-team exercises with your engineering team. SOC 2 evidence package generated automatically.

MDR bought alone vs. MDR delivered by Jacobian
The platform is the easy part to buy
| Feature | A standalone MDR license | MDR delivered by Jacobian |
|---|---|---|
| Detection Tuning | Generic rules tuned by analysts who don't know your stack | Rules tuned by the engineers who already operate your infrastructure |
| Response Integration | Separate vendor portal, separate on-call rotation, two-step escalation | Wired into your existing PagerDuty rotation; one team owns it |
| Incident Containment | Vendor opens a ticket, your team executes containment | Pre-written playbooks executed by us, you ratify the action |
| Audit Evidence | Separate vendor evidence pack, manual reconciliation with SOC 2 controls | Detection events feed directly into SOC 2 / HIPAA control library |
| Threat Hunting | Optional add-on, often skipped | Quarterly hypothesis-driven hunts mapped to MITRE ATT&CK |

Monitoring & Incident Response
MDR and infrastructure incident response share the same rotation -- one team, two skill sets, lower handoff cost. Continuous security detection lives in MDR; systems and servers live here.
Penetration Testing
Pen-test findings inform detection rule design; MDR detects attacks the pen-test discovered are possible.
Compliance Management
Detection events feed directly into the SOC 2 / HIPAA / ISO 27001 evidence library -- monitoring as compliance, not separate from it.
