Defender for Endpoint, India

Enterprise EDR that replaces your third-party antivirus, deployed without a coverage gap.

Microsoft Defender for Endpoint is detection and response, not just antivirus. We onboard Windows, macOS, Linux, iOS and Android, roll out attack surface reduction in audit-then-block, tune automated investigation, and migrate you off McAfee, Symantec or CrowdStrike without a single unprotected hour. Remote-first from Gachibowli, Hyderabad, for organisations across India.

What Defender for Endpoint does

Eight capabilities that separate EDR from the antivirus you run today.

A legacy antivirus asks one question: does this file match a known signature? Defender for Endpoint watches behaviour, records telemetry, investigates alerts on its own, and can isolate a machine from the network in one click. These are the eight capabilities we deploy and tune on every engagement.

Endpoint detection and response

Behavioural sensors record process, file, registry and network activity on every device. When something malicious runs, you get the full attack story: entry point, lateral movement, persistence, and every affected machine, not just a quarantine popup.

Next-generation protection

Cloud-delivered antimalware with behaviour-based blocking replaces your signature-based AV outright. Fileless attacks, living-off-the-land binaries and script-based malware are caught by what they do, not what they look like.

Attack surface reduction rules

Policy rules that block the behaviours ransomware depends on: Office apps spawning child processes, obfuscated scripts, credential theft from LSASS, untrusted USB executables. We roll them out in audit mode first so nothing breaks unannounced.

Automated investigation and response

When an alert fires, Defender investigates it the way an analyst would: examines the file, checks prevalence, inspects related processes, then quarantines or remediates. Your team reviews verdicts instead of drowning in raw alerts.

Vulnerability management

Continuous discovery of missing patches, vulnerable software versions and misconfigurations across the estate, prioritised by exploit context. No scan windows, no separate scanner agent, no network credentials to manage.

Web content filtering

Category-based web filtering enforced by the endpoint itself, on or off the corporate network. Block gambling, adult content or personal cloud storage for the whole company or per device group, with reporting in the same portal.

Tamper protection

Ransomware operators disable antivirus before they encrypt. Tamper protection stops anyone, including a local administrator, from switching off real-time protection, deleting security intelligence or killing the sensor service.

One portal, Sentinel-ready

Every alert, investigation and device lands in the Microsoft Defender portal alongside identity and email signals. When you are ready for a SIEM, the connector streams the same telemetry into Microsoft Sentinel natively.

EDR vs legacy antivirus

Why detection and response replaces antivirus instead of sitting next to it.

The antivirus model assumes threats can be recognised before they run. Modern intrusions are built to defeat exactly that assumption: signed binaries, stolen credentials, PowerShell that never touches disk. EDR assumes something will eventually get through and makes sure you can see it, trace it and contain it when it does. That is a different product category, and it is why insurers, auditors and boards now ask for EDR by name.

  • A signature AV answers "is this file known-bad". EDR answers "what happened on this machine, when, and where did it spread". After an incident, only the second question matters.
  • Legacy AV has no memory. MDE keeps a searchable timeline of process, network and file events, so an investigation that starts today can look back at what actually happened.
  • Response actions are built in: isolate a device from the network while keeping the sensor connection alive, collect an investigation package, run a remote antivirus scan, block a file across the whole estate by indicator.
  • Running two real-time engines on one machine causes conflicts and slowdowns rather than doubling protection. The correct end state is Defender active and the old agent fully removed, reached through a managed migration, not a big-bang uninstall.

Why GR IT for MDE

Four reasons to run this deployment with us.

Defender for Endpoint is easy to switch on and easy to ruin. Blind-blocked ASR rules break finance apps, untuned alerts train people to ignore the console, and half-migrated estates run two AV engines at once. Here is how we do it differently.

Deployed across 80+ tenants

We have onboarded Defender across SMBs on Business Premium, mid-market firms consolidating agents, and regulated enterprises. The collision patterns, the exclusions that matter, the ASR rules that bite Indian line-of-business software: we have the pattern library.

Audit-then-block, always

No ASR rule goes to block mode without an audit period and a reviewed collision list. No automation level is defaulted. The deployment sequence is documented, ringed and reversible at every step, which is why our rollouts do not generate helpdesk fires.

Remote-first from Hyderabad

Delivered remotely from Gachibowli, Hyderabad to organisations across India, because endpoint deployment is portal and policy work, not desk visits. Managed clients get a 30 minutes response SLA, and scheduled on-site work is available where a project genuinely needs hands on hardware.

Evidence your auditors accept

DPDP Act reasonable security safeguards, CERT-In incident reporting timelines, ISO 27001 and insurer questionnaires all get answered from Defender telemetry and configuration exports. We package the evidence as part of the engagement, not as an afterthought.

Onboarding approaches

Three ways to onboard devices, and when each one is right.

Onboarding is how a device starts reporting to your Defender tenant. The right method depends on how the estate is managed today, and most Indian organisations end up using two of the three in combination. A licence with no devices onboarded protects nothing, so this is where every engagement starts.

Intune, the managed path

For estates already enrolled in Microsoft Intune, onboarding is a policy push. Defender policies, ASR rules, tamper protection and web filtering all deploy from the same console, and compliance status feeds back into conditional access.

  • Onboarding profile pushed per device group
  • Security settings management for policies
  • Conditional access can require a healthy device
  • Best long-term operating model for most estates

Group Policy, the AD path

Domain-joined estates without Intune onboard through Group Policy or Configuration Manager. The onboarding package deploys as a GPO, and ASR rules and antivirus policy follow through the same mechanism your team already operates.

  • No new management infrastructure required
  • Works for servers as well as workstations
  • Policies managed through familiar GPO tooling
  • Common bridge while an Intune rollout is planned

Local script, the gap filler

Workgroup machines, one-off servers and lab devices onboard with a local script. It is the right tool for the last few percent of the estate, and the wrong tool for the first ninety, because script-onboarded devices still need a policy source.

  • Onboards a device in minutes with no dependencies
  • Right for workgroup and unmanaged machines
  • Policy still needs Intune, GPO or portal management
  • We use it to close the tail, not run the estate
Who needs this

Six Indian situations where MDE is the right move.

The recommendation differs by size and licensing position. In the first case, the most common one in India, the answer is to deploy something already owned, which is the cheapest security project available.

SMBs already on Business Premium

Microsoft 365 Business Premium includes Defender for Business, which carries EDR, automated investigation and vulnerability management. If you are under 300 users and paying a third-party AV renewal on top, you are buying a weaker product than the one sitting idle in your licence.

Enterprises consolidating agents

Estates running a separate AV, a separate vulnerability scanner, a separate web filter and a separate EDR carry four agents, four consoles and four renewals. MDE collapses all four into one platform your Microsoft licensing already anticipates, with one incident queue.

Boards worried about ransomware

When the board asks what stands between the company and an encryption event, "we have antivirus" is no longer an answer. ASR rules, controlled folder access, tamper protection and automatic attack disruption are the specific controls that break the ransomware kill chain.

Regulated and DPDP-exposed firms

The DPDP Act expects reasonable security safeguards around personal data, and CERT-In directions require rapid incident reporting. EDR telemetry is what lets you detect an incident quickly, establish its scope, and report accurately within the required timelines instead of guessing.

Healthcare and patient data

Hospitals and diagnostics groups hold exactly the data ransomware crews target, on estates full of shared workstations. Device control, web filtering and EDR with automated response protect endpoints that no individual user owns or watches.

IT services and client-facing firms

Companies whose clients audit them, IT services, BPO, accounting and legal, increasingly face security questionnaires that ask for EDR by name. A tuned MDE deployment with documented configuration answers those questionnaires with evidence rather than assurances.

Every platform, one console

What MDE coverage looks like on each operating system.

Defender for Endpoint is not a Windows-only product, and Indian estates are rarely Windows-only either. Pick a platform to see what the sensor delivers there and what we configure during onboarding.

The deepest coverage: EDR, ASR, tamper protection, the full set

Windows 10 and 11 have the sensor built into the operating system, so onboarding is configuration, not agent installation. Windows Server onboards with its own licensing. This is where ASR rules, controlled folder access and automated investigation deliver their full value.

  • Built-in sensor, no third-party kernel driver
  • Full ASR rule set rolled out audit-then-block
  • Tamper protection enforced from the cloud
  • Automated investigation and response on every alert

EDR vs what you run today

Defender for Endpoint against a legacy signature antivirus.

The honest comparison is not Defender versus nothing, it is Defender versus the third-party AV you already pay for. A signature product still stops commodity malware. What it cannot do is show you an attack in progress or let you respond to one, and those are the capabilities incidents actually demand.

Defender for Business vs Plan 1 vs Plan 2.

The plan names confuse almost everyone, so here is the comparison laid out plainly. The counter-intuitive part: Defender for Business, the small business product included in Microsoft 365 Business Premium, has detection and response capabilities that Plan 1, the enterprise product inside Microsoft 365 E3, does not. Where Microsoft marks a capability as optimised for smaller organisations, that is preserved below.

How the engagement runs

From licence check to managed operations, in five steps.

A typical estate of a few hundred devices completes onboarding and migration in 4-8 weeks. The first step regularly changes the shape of everything after it, because a meaningful share of organisations discover they already own the product.
  1. 1

    Licence and estate discovery

    Week 1

    We establish which Defender plan your Microsoft licensing already includes, count real devices against what any console claims, and inventory the incumbent AV. Output: a written map of what you own, what needs licensing, and the migration wave plan.

  2. 2

    Pilot onboarding

    Week 1-2

    A pilot ring onboards via Intune, GPO or script as fits your management stack. Defender runs in passive mode alongside the existing AV, ASR rules go to audit, and we validate sensor health, performance and exclusions before touching the wider estate.

  3. 3

    Estate rollout and AV migration

    Week 2-6

    Wave by wave: onboard, verify health, remove the old agent with vendor tooling, confirm Defender is active, enable tamper protection. Windows first typically, then macOS with MDM profiles, Linux servers in maintenance windows, mobile last.

  4. 4

    Hardening and tuning

    Week 4-8

    ASR rules promoted to block in rings, web content filtering policies applied, automated investigation trust levels set per device group, alert noise tuned, and vulnerability management findings routed into your patching workflow.

  5. 5

    Handover or managed operations

    Continuous

    Either your team takes over with documented runbooks and training, or we operate it: alert triage, incident response, monthly reporting and quarterly tuning under a managed contract with a 30 minutes response SLA.

The two rollouts that decide success

ASR in audit-then-block, and learning to trust automated investigation.

Two parts of an MDE deployment are done badly almost everywhere: attack surface reduction rules switched straight to block mode, and automated investigation left in the default because nobody trusts it yet. Both have a correct sequence, and both reward patience.
  1. 01
    ASR phase 1· 2-3 weeks

    Every rule in audit mode

    All attack surface reduction rules run in audit, logging what they would have blocked without blocking anything. This surfaces the line-of-business collisions before users feel them: the Tally add-in that spawns processes from Excel, the legacy ERP updater that looks exactly like malware behaviour.

    • Full ASR rule set deployed in audit mode
    • Audit telemetry reviewed weekly
    • Collision list per rule with affected apps
    • Exclusions drafted and justified in writing
  2. 02
    ASR phase 2· 2-4 weeks

    Block mode in rings

    Rules that audited clean move to block for a pilot ring, then the wider estate. Rules that hit legitimate software get targeted exclusions or warn mode, never a blanket disable. The end state is documented: which rules block, which warn, what is excluded and why.

    • Ring-based promotion, pilot then estate
    • Warn mode where users need an override path
    • Signed-off exclusion register
    • ASR state documented for auditors
  3. 03
    AIR phase 1· First month

    Automation with human approval

    Automated investigation runs on every alert, but remediation actions wait for approval. Your team, or ours under a managed contract, reviews each verdict. This is the trust-building period: you watch what the automation would have done and confirm it is right.

    • AIR enabled across all device groups
    • Remediation pending approval, human in the loop
    • Weekly verdict review with false-positive log
    • Device group design for graduated automation
  4. 04
    AIR phase 2· From month 2

    Full automation where it earned it

    Device groups where verdicts have proven accurate move to full automation: malware is quarantined and remediated at machine speed, at 3am, without waiting for a human. Sensitive groups, such as servers and executive devices, can stay on approval deliberately. The point is that the automation level is chosen, not defaulted.

    • Full automation on proven device groups
    • Deliberate approval gates on sensitive groups
    • Response time measured in minutes, not mornings
    • Quarterly review of automation levels
Straight answers

Defender for Endpoint, the questions Indian IT leads actually ask.

Migration without a gap

The zero-gap checklist for leaving McAfee, Symantec or CrowdStrike.

The dangerous moment in any AV migration is the window between removing the old agent and confirming Defender is active. Our migration method makes that window zero: Defender goes on first in passive mode, proves itself healthy, and only then does the old product come off. This is the checklist we run per migration wave.

Before anything is removed

  • Defender sensor onboarded on every wave device
    Defender Antivirus runs in passive mode alongside the incumbent, EDR telemetry already flowing.
  • Sensor health verified per device
    A device that never reported in is a device that will be unprotected after the uninstall.
  • Exclusions translated, not copied
    Ten years of accumulated third-party exclusions get reviewed; most are stale, some are dangerous.
  • Wave plan agreed
    Pilot ring, then departments, servers handled in their own maintenance windows.

The switchover

  • Old agent removed with the vendor removal tool
    Standard uninstalls leave drivers and filter services behind that keep Defender passive.
  • Defender flips from passive to active automatically
    On Windows, removing the third-party product promotes Defender Antivirus without a reboot dependency.
  • Active mode confirmed per device, not assumed
    We verify protection state from the portal for every migrated device before the wave closes.
  • Tamper protection switched on immediately
    The estate is never left in the state where one script can disable its new protection.

After the wave

  • Old management servers decommissioned
    ePO or SEPM servers left running become unpatched attack surface with admin reach.
  • Old licence renewal cancelled on the calendar
    The commercial saving is real only when the renewal actually stops.
  • Performance baseline compared
    Boot time and scan impact measured before and after, so the "Defender is slow" debate is settled with data.
  • Incident response runbook updated
    Isolation, investigation and rollback steps now reference the Defender portal, not the old console.
