Insyto Managed Services

Managed Security Services

Insyto operates your Microsoft security environment: reviewing alerts, maintaining detections and coordinating response across identity, endpoints, email and cloud. We agree what we monitor, what we can act on and when your team takes over.

When your team needs an operating partner

IT and security leaders with Microsoft Defender or Sentinel in place who need consistent operational follow-through alongside their internal team.

  • Alerts accumulate without a clear investigation owner or escalation path.
  • Disconnected identity, endpoint and cloud signals make incidents difficult to assess.
  • Detection rules and exceptions are not reviewed as the environment changes.
  • Security findings reach IT teams without tracked remediation or closure.

What Insyto manages

The engagement covers the agreed security workloads and their operating procedures. We maintain detection coverage, investigate relevant signals and track decisions through to the responsible team.

Microsoft Defender XDR

Alert triage and investigation

Review alerts in context so security activity has a documented next action.

  • Correlate available identity, endpoint and email evidence.
  • Record investigation findings, severity and escalation decisions.
  • Track unresolved incidents and handoffs to your security or IT owners.

Microsoft Sentinel and Defender XDR

Detection and telemetry maintenance

Keep the agreed monitoring configuration aligned with the systems it protects.

  • Review connected data sources and gaps in available telemetry.
  • Tune detection rules and approved exclusions as usage changes.
  • Maintain documented response playbooks and review automation permissions.

Defender, Entra ID and Intune

Response coordination

Connect an investigation to the people authorized to contain and remediate it.

  • Carry out actions permitted by the agreed response playbook.
  • Coordinate account or device actions with identity and endpoint administrators.
  • Escalate decisions that require business approval or specialist incident response.

Microsoft security controls

Security posture follow-through

Keep configuration findings visible after the initial assessment or deployment.

  • Review security configuration and vulnerability findings available in the agreed tools.
  • Assign remediation actions with owners and agreed priorities.
  • Report detection gaps, recurring alerts and unresolved risks.

Monitoring coverage, response targets and specialist incident-response support are agreed explicitly. This page does not promise round-the-clock SOC coverage or unlimited incident response.

Define response authority before the first alert

Handover establishes monitored workloads, available licenses and telemetry, service hours, severity criteria and escalation contacts. We agree which actions can proceed under a playbook and which need explicit approval. Missing connectors or major deployment work are scoped separately.

Your team retains risk acceptance, business-impact decisions and approval of disruptive actions. Microsoft operates the cloud platforms. Insyto owns the monitoring, investigation and reporting tasks specified in the engagement.

Operating records and regular reviews

  • A monitored-system inventory and agreed escalation matrix.
  • Investigation records, detection changes and approved response procedures.
  • A remediation backlog with owners, exceptions and status.
  • Service reviews covering alert patterns, coverage gaps and next actions.

How the service moves into steady operation

  1. 01

    Onboard

    Confirm licensed tools, data sources, monitored systems, contacts and approved response authority.

  2. 02

    Stabilize

    Document detection gaps, noisy alerts and unresolved findings before routine operations begin.

  3. 03

    Operate

    Triage in-scope signals, maintain detections and coordinate approved containment or escalation.

  4. 04

    Improve

    Review recurring alerts, telemetry gaps and remediation status with the responsible owners.

From assessment to ongoing operations

Start with the work your environment needs. Assessment and implementation are separate engagements, not recurring managed-service tasks.

Professional Services

Implement and modernize

Deploy or integrate the tools, telemetry and initial detections that operations will maintain.

Defender & Sentinel Implementation

Managed Services

Operate and optimize

Operate the established security controls, investigate signals and maintain an accountable remediation process as the environment changes.

Review operating responsibilities

Coordinate the related operating responsibilities

Managed Endpoint Management

Endpoint operations maintain device configuration and compliance. Security operations coordinate threat-related device actions.

Adjacent services are coordinated when included in your engagement; linking them here does not bundle their scope.

Delivery experience and operating guidance

Knowledge Center

Incident response planning

Define decision authority, escalation and communication before an incident requires them.

Case study

Zero Trust for life sciences

An example of identity, device and governance controls working together. This is implementation evidence, not a managed-response guarantee.

Technology relationships

  • Microsoft security platform

    Defender XDR, Sentinel, Entra and Intune supply the Microsoft signals and controls in this service.

  • Sophos

    A separate security-platform option; Sophos coverage is not implied by the Microsoft operating scope.

  • Proofpoint

    Email and human-risk context for separately scoped protection decisions.

Industry context

Life Sciences & Healthcare

Identity, device and data-control ownership matters when security findings involve sensitive research or care workflows.

Insyto is based in Valley Center and serves organizations across San Diego County, including Carlsbad, Vista, San Marcos, Encinitas and Oceanside. Explore our service areas and San Diego consulting context.

Establish ownership across your security tools

Bring your current Defender and Sentinel scope, escalation process and unresolved operational gaps. We can define the responsibilities your team retains and the security operations Insyto would manage.
