IPSIP Vietnam strengthens Microsoft Defender MDR capabilities for businesses
Microsoft Defender is becoming an important part of the security architecture of many businesses using the Microsoft ecosystem. However, deploying Defender addresses only part of the challenge. Its real value depends on whether a business has sufficient resources to continuously monitor alerts, investigate incidents, and take response actions when threats emerge.
IPSIP Vietnam currently provides security monitoring and operations for customers using Microsoft Defender for Endpoint and Microsoft Defender for Servers. The scope extends beyond monitoring to include containment, forensic investigation, Live Response, KQL-based threat hunting, automation, and tuning.
This is how IPSIP Vietnam transforms Microsoft Defender from a detection platform into part of a Managed Detection & Response (MDR) process that can support businesses throughout the incident lifecycle.
From Microsoft Defender alerts to a complete MDR process
One common challenge for businesses is not a lack of alerts, but a lack of personnel with enough time and experience to determine which alerts genuinely require action.
In the MDR model, IPSIP provides the operational layer behind Microsoft Defender: receiving security signals, analyzing context, investigating events, and performing or coordinating response actions within the agreed scope.
IPSIP's MDR capabilities documentation confirms an end-to-end monitoring scope across Defender for Endpoint and Defender for Servers, including active containment, KQL hunting, Live Response, and tenant remediation.
Businesses seeking to understand the difference between owning a tool and engaging an operations team can read about MDR services and how the model works.
IPSIP Vietnam can proactively isolate endpoints when threats are detected
When an endpoint shows signs of compromise, containment speed is critical to limiting an attacker's ability to continue using the device as a foothold.
One of IPSIP Vietnam's Microsoft Defender response capabilities is isolating compromised endpoints from the network.
Microsoft Defender for Endpoint supports the isolate device action while maintaining the connection required for the Defender service so that analysts can continue investigating and responding. The platform also supports other response actions, such as collecting an investigation package and initiating a Live Response session.
In MDR operations, what matters is not simply that the tool has an isolate button. Analysts must determine when isolation is appropriate, assess its potential business impact, and take action according to the customer-approved response process.
This is also why businesses need to establish an incident response process before an incident occurs. IPSIP provides dedicated resources on information security incident response services and a SOC incident investigation handbook within its existing content library.
Beyond endpoint protection: IPSIP Vietnam supports identity response
A modern incident does not necessarily stop at the device.
If an attacker has compromised a user account, remediating the endpoint while leaving the compromised credentials unchanged may provide another route into the system.
IPSIP's Microsoft Defender MDR scope can therefore include disabling or suspending compromised Microsoft Entra ID or Active Directory accounts, subject to the authority and response procedures defined for the customer's environment.
Microsoft Defender XDR supports identity response actions, including Disable user. Depending on the architecture, Microsoft Defender can also coordinate actions across Active Directory and Microsoft Entra ID to prevent further sign-ins or lateral movement.
This is particularly important as endpoints, identities, and cloud applications become increasingly interconnected.
A compromised account can become a starting point for accessing data, email, or other SaaS applications. IPSIP also provides a dedicated analysis of OAuth token risks in enterprise environments.
Handling phishing across the tenant instead of one mailbox at a time
Email is another layer that needs to be incorporated into the overall response process.
IPSIP's service scope can include remediating and purging phishing emails across mailboxes within a tenant, using appropriate Microsoft ecosystem mechanisms such as Zero-hour Auto Purge or soft delete where permitted.
Microsoft describes Zero-hour Auto Purge (ZAP) as a capability that takes action on messages after they have been delivered to Exchange Online mailboxes when the system subsequently identifies them as phishing or spam. Microsoft Defender XDR also supports email deletion actions, including a soft-delete option in appropriate response workflows.
This prevents response activities from being limited to telling users to "delete the email" and enables more centralized remediation within the configured scope and permissions.
For businesses using Microsoft 365, this is an important layer because a phishing campaign rarely targets only one user. IPSIP also provides content on phishing campaigns targeting Microsoft 365 users, helping businesses understand related attack scenarios.
Live response and forensics enable analysts to go beyond an alert
When the initial alert does not provide enough information, analysts need the ability to inspect the endpoint directly.
Within IPSIP's MDR scope, the team can collect a forensic investigation package or initiate a Live Response session to support the investigation.
According to Microsoft documentation, Defender for Endpoint enables analysts to collect an investigation package containing additional forensic data about the device's state. Live Response provides a remote interactive environment where investigators can perform investigation and response actions on supported endpoints.
This is an important step when the SOC needs to answer more detailed questions:
What actions did the device perform? Are there any suspicious artifacts? Are there processes or files that require inspection? Is the impact limited to one endpoint, or should the investigation be expanded?
The ability to move from an alert to forensic evidence helps analysts avoid making decisions based on a single isolated signal.
KQL threat hunting: Proactively searching for indicators that have not triggered alerts
MDR should not operate solely on the principle of "wait for an alert, then respond."
IPSIP also includes KQL-based threat hunting within its Microsoft Defender operations, together with automation and tuning to improve monitoring effectiveness.
Microsoft Defender XDR Advanced Hunting uses Kusto Query Language (KQL) in advanced mode, enabling analysts to query security data for suspicious behaviors or relationships that may not yet have been identified by an existing detection rule.
From an operational perspective, threat hunting can allow analysts to pivot between device activity, identity data, and email telemetry to expand an investigation after identifying a suspicious indicator.
For IPSIP, KQL is not treated as an isolated feature. It is a tool that supports analysts throughout the detect – investigate – hunt – respond – tune cycle.
This approach also aligns with IPSIP's XDR model, in which security signals from multiple layers can be analyzed within the same investigative context.
Monitoring endpoints and servers within a unified security strategy
Another notable aspect of IPSIP's scope is its ability to monitor both Defender for Endpoint and Defender for Servers.
This is important for businesses with environments combining user workstations and server workloads.
According to Microsoft, Defender for Servers integrates with Defender for Endpoint to provide EDR, investigation, and threat-detection capabilities for servers. This architecture can protect both Windows and Linux systems in supported environments.
For IPSIP, the purpose of monitoring is not to create another dashboard. It is to bring endpoints and servers into a security operations process with clearly assigned responsibility for monitoring and response.
Businesses requiring continuous monitoring can also explore IPSIP's 24/7 SOC services. This URL has been verified in IPSIP's Internal Link Inventory.
Conclusion
IPSIP's Microsoft Defender capabilities are built on real-world monitoring for customers using Defender for Endpoint and Defender for Servers, with a response scope that includes endpoint isolation, identity containment, email remediation, Live Response, forensic collection, automation, tuning, and KQL threat hunting.
Importantly, IPSIP does not claim a direct partnership with Microsoft without verified supporting information. Its demonstrated value lies in its ability to operate the Microsoft Defender ecosystem within an MDR model for customers.
Rather than simply providing another tool, IPSIP adds the analysts and processes businesses need to turn Defender's capabilities into real-world detection and response operations.
Businesses using Microsoft Defender that want to strengthen their monitoring, investigation, or MDR capabilities can contact IPSIP Vietnam to discuss an appropriate operational scope.
