Cybersecurity — MDR
Managed detection and response for New York businesses
EDR/XDR telemetry from every endpoint and identity, watched around the clock by our tooling, triaged by engineers, and contained under authority you granted in writing — before an intrusion becomes an incident.
What managed detection and response actually is
Endpoint protection stops what it recognizes. MDR exists for what it does not: the attacker signing in with a stolen password, the legitimate admin tool doing something no admin asked for, the quiet persistence mechanism planted for later. Detection and response means someone is watching that gray area and has the standing to act on it.
The mechanics are concrete. An EDR/XDR agent on every endpoint and server streams telemetry — process activity, sign-ins, network connections, script execution. Detection rules and behavioral analytics flag what deviates from your environment’s normal. Our tooling watches that stream around the clock; an engineer is paged the moment something crosses a threshold worth a human. We describe the staffing model this plainly because much of the market does not — see how our security operations are staffed.
MDR is one discipline inside our managed cybersecurity practice. It pairs with the log pipeline for visibility beyond endpoints, with vulnerability management to shrink what attackers can use, and with incident response when containment needs to become recovery.
From signal to resolution
The escalation flow is agreed before onboarding finishes, so nobody is improvising at 3 a.m.
Collect
Agents deploy to endpoints and servers; Entra ID and Microsoft 365 signals are joined in, so a suspicious sign-in and a suspicious process read as one story instead of two ignored alerts.
Detect
Vendor analytics plus detection rules we tune to your environment. A noisy detection is treated as a broken one — tuning is scheduled work, not an apology.
Triage
An engineer determines real or benign and enriches the finding with context: which user, which device, what data sits behind it, what happened in the minutes around it.
Contain
Isolate the host, disable the account, kill the process — under standing authority documented in your agreement, so containment does not wait for a meeting.
Escalate
You are notified through the escalation path in your playbook. If scope demands it, the event moves to incident response with the timeline already assembled.
Close the loop
Root cause feeds back into patching and configuration, and the monthly report is written to be handed to an insurer, auditor, or client questionnaire.
What’s included
EDR/XDR deployment and tuning
Agent rollout across endpoints and servers, with detections tuned to your environment rather than left at defaults.
Identity signal integration
Entra ID sign-in and audit events correlated with endpoint telemetry — most modern intrusions show up in both.
Detection engineering
Custom rules for your specific risks: finance-team mailbox rules, admin tool misuse, after-hours data movement.
Containment authority in writing
What we may isolate, disable, or block without a phone call — decided by you, documented in the agreement.
Engineer escalation
Alerts that cross the line page a person. The escalation path, with names and order, is published to you.
Evidence-grade reporting
Monthly reporting written for the people who ask: insurers at renewal, auditors, client security reviews.
Where MDR fits
Most intrusions we are built to catch start with a phished credential or an unpatched, internet-facing service. MDR is the discipline that notices when prevention has already failed — which is why it works best beside identity hardening and vulnerability management, which shrink the number of detections that ever matter.
It is also the control your cyber-insurance application means when it asks about EDR or managed detection. Those answers become warranties in a claim, so we keep deployment evidence current — coverage reports, not screenshots from onboarding week.
Common questions
What is the difference between EDR and MDR?
EDR is the product: the agent that records endpoint telemetry and can act on it. MDR is the service: the people and process that watch the telemetry, decide what is real, and respond. Buying EDR without MDR is buying a smoke detector and mailing yourself the alerts.
Is this a staffed 24×7 SOC?
No. Our tooling watches continuously and pages an engineer when a detection crosses an agreed threshold; pre-authorized containment actions do not wait for the page to be answered. We publish the model plainly on the security operations page instead of claiming a SOC floor we do not operate.
What happens when something fires at 3 a.m.?
Containment that you pre-authorized happens immediately — an infected laptop gets isolated whether or not anyone is awake. An engineer is paged for triage, and you wake up to a report of what happened and what was done, not a voicemail asking for permission.
We already have Microsoft Defender. Do we still need MDR?
Often Defender is exactly the right agent — many of our deployments run on Microsoft security tooling you already license. MDR is the question of who watches it, tunes it, and acts on it. We would rather operate the licenses you own than sell you a second agent.
Our insurance application asks whether we have EDR/MDR. Does this count?
This is the control that question describes: endpoint detection deployed, monitored, and backed by a response process. We supply the deployment and monitoring evidence; the application answers themselves belong to you and your broker.
What does MDR cost?
The market prices MDR per endpoint per month, with wide variance driven by what “response” actually includes — some quotes end at notification. Ours is flat monthly pricing with the containment scope written into the agreement, so you can compare quotes on what happens after the alert, not just the per-seat number.
