POWERED BY INDUSTRY-LEADING TECHNOLOGY PARTNERS
Managed Detection and Response (MDR) is a managed cybersecurity service in which a provider delivers 24/7 threat monitoring, detection, alert investigation, threat hunting, incident response and containment as an operated outcome — not as software your team has to run.
The distinction matters commercially. EDR, XDR and SIEM are detection technologies: they generate signals. Someone still has to staff the night shift, tune the detections, separate real incidents from noise, investigate what the tooling flags, and act when something is confirmed. An MDR provider takes on that operational work.
NetNXT's security analysts run the detection stack, hunt for activity the tooling alone would not surface, investigate every alert to a conclusion, and take containment action across endpoints, network, cloud and identity — so IT and security leaders get enterprise security operations without building a team to run them.
Continuous security operations are the foundation. Proactive threat hunting, full investigation and analyst-led response are what make it MDR.
Continuous monitoring of endpoint, network, cloud and identity telemetry by security analysts — every shift, weekend and public holiday. Signals are correlated across sources, analysed in context, and escalated to you only when they represent a confirmed incident.
Analyst-driven hunting for activity that automated detection does not flag on its own — credential misuse, lateral movement, living-off-the-land techniques and persistence. Hypotheses are built from MITRE ATT&CK techniques and current threat intelligence, then tested against your live telemetry.
Confirmed incidents move straight into response: investigation, endpoint and account isolation, containment, and step-by-step remediation guidance — executed by our analysts against defined response playbooks, not handed back to your team as a ticket.
Global and regional threat intelligence applied directly to your environment — active ransomware operations, phishing infrastructure and attacker TTPs — used to enrich alerts, prioritise investigation and tune detections as campaigns targeting enterprises in India evolve.
You should not be chasing alerts. Every detection is triaged, enriched with asset, user and threat context, and investigated to a verdict by our analysts. What reaches your team is a short list of confirmed, prioritised incidents with the evidence and recommended action already attached.
Detection, investigation and response activity is documented and reportable — giving you an evidence trail and incident records that support security monitoring and incident-reporting obligations under frameworks such as ISO 27001, SOC 2, the DPDP Act and CERT-In.
Onboard, detect, hunt, respond. Four stages that take an environment from unmonitored to continuously defended — and take an individual signal from first detection to documented containment.
We connect security telemetry across the environments you already run — no rip-and-replace.
Signals from every source are correlated and evaluated together, so activity that looks harmless in isolation is caught in sequence.
This is where managed detection and response goes beyond watching a queue. Our analysts actively look for what has not alerted, and investigate what has, until there is a verdict.
Containment first, documentation immediately after — so the incident is closed and the record exists.
Security analysts, threat hunters and incident responders covering your environment around the clock — without recruiting, training and retaining a 24/7 rota. You get the operating capability of a security team; your IT team gets its week back.
Continuous monitoring shortens the time to detect (MTTD). Analyst-led investigation and response shorten the time to contain (MTTR). Together they reduce the window in which an attacker can operate undetected inside your environment.
Extend 24/7 detection and response coverage without funding the headcount, tooling and infrastructure a continuously staffed in-house SOC requires — and without the hiring timeline that comes with it.
Add endpoints, cloud accounts, new offices or an acquired business unit and coverage extends with them — under one managed detection and response service, one set of detections, and one escalation path. No new tooling to procure, no new rota to staff.
Three ways to cover detection and response. The right one depends on the headcount, tooling budget and response capability you already have.
CERT-In directions require qualifying cyber incidents to be reported within six hours of detection, and the DPDP Act 2023 introduces breach-notification duties alongside an expectation of reasonable security safeguards. Both assume something most organisations do not have: someone watching, and someone able to establish what happened, at 2 a.m.
That is the gap NetNXT MDR fills. Continuous monitoring means incidents are detected rather than discovered later. Analyst-led investigation establishes scope and root cause quickly. And every detection, investigation and response action is documented — giving your team the incident record and evidence trail needed to support its own reporting and audit obligations.
NetNXT MDR supports these obligations. It does not discharge them — reporting decisions and regulatory filings remain yours.
We replaced a patchwork of alerts nobody had time to chase with NetNXT's managed detection and response team. Within the first month they had already contained two incidents we would never have caught in time on our own.

The detection platform layer — telemetry from endpoint, network, cloud, identity and email correlated into one system. MDR is the team that operates a platform like this on your behalf.
Centralised log collection, analytics and correlation across your environment. AI SIEM produces the signal; MDR analysts investigate and act on it.
Continuous security operations — monitoring, triage and escalation. MDR builds on that operating model and adds proactive threat hunting and provider-led response.
Manage, configure and secure every device in the estate — the same endpoints MDR monitors for threat activity.
Protection and threat detection for the APIs and AI services you expose — extending monitored surface beyond endpoint and network.
Broader managed security operations and administration across your infrastructure; MDR is the detection-and-response function within that scope.
Managed Detection and Response is a managed cybersecurity service in which a provider delivers 24/7 threat monitoring, detection, alert investigation, threat hunting, incident response and containment on your behalf. Rather than buying a detection tool your team has to operate, you get security analysts who run the technology, investigate what it flags, hunt for what it misses, and act on confirmed threats across endpoints, network, cloud and identity.
EDR detects and responds to threats on endpoints. SIEM centralises and analyses logs from across your environment, but needs a team to operate and tune it. XDR correlates telemetry across endpoint, identity, cloud and network in a single platform. All three are technologies. MDR is the managed service layer above them: analysts operating EDR, XDR and SIEM technology 24/7, investigating alerts to a verdict and taking response action — so the outcome you buy is detection and response, not a product licence.
MDR pricing depends on the number of protected endpoints, cloud workloads, identity sources, required integrations and the level of managed response included. Compared to building an in-house SOC — hiring, training and retaining 24/7 analyst coverage — NetNXT's managed MDR typically runs up to 70% lower in total cost of ownership. NetNXT provides a tailored quote after a short assessment of your environment.
It supports them. CERT-In directions require qualifying incidents to be reported within six hours of detection, and the DPDP Act 2023 sets breach-notification duties alongside reasonable security safeguards. NetNXT MDR provides the continuous monitoring that surfaces incidents in the first place, the analyst-led investigation that establishes scope and root cause, and documented detection, investigation and response records that give your team the evidence needed for reporting and audit. Regulatory filings and reporting decisions remain your organisation's responsibility. NetNXT MDR provides the detection, investigation and documentation that support them; it does not by itself make an organisation compliant.
Most environments move to active monitoring within weeks rather than months. Onboarding covers endpoint and server agent deployment, network and firewall log integration, cloud telemetry ingestion across AWS, Azure and GCP, and identity and SaaS connectors, followed by detection configuration and tuning before 24/7 monitoring goes live. Timelines depend on the number of sites, log sources and integrations in scope; we confirm a schedule during the assessment.
NetNXT's MDR includes 24/7 SOC monitoring, expert-led threat hunting, rapid incident response with sub-15-minute MTTR, global threat intelligence correlation, alert triage and investigation by analysts, and compliance and audit reporting for ISO 27001, SOC 2, DPDPA and CERT-In.
Selecting the right MDR provider is as important as the technology behind it. NetNXT combines expert SOC analysts, proven incident response playbooks, and deep experience with Indian compliance requirements — CERT-In and DPDPA — to reduce deployment risk, cut detection and response times, and give IT and security leaders a dedicated security team without the overhead of building one in-house.
