Executive Summary

Iyuno, a global media localization and technology services company, embarked on a strategic initiative to strengthen its Microsoft 365 security posture across identities, endpoints, and cloud applications. Operating across multiple regions and supporting critical content workflows, Iyuno required a modern, intelligence‑driven security approach that could reduce risk without disrupting business operations.

To support this objective, Iyuno partnered with Ravanty to design and deploy a targeted threat protection and endpoint security engagement using Microsoft’s Defender and Entra security stack. The engagement focused on validating Iyuno’s existing environment, deploying controlled security policies in production, and enabling Iyuno’s security leadership to evaluate Microsoft Defender for Endpoint and Defender for Cloud Apps as scalable, long‑term security platforms. The project was delivered using Ravanty’s structured IDARE framework and supported by Microsoft security funding programs.

The Opportunity

Iyuno approached this initiative with a clear goal: gain stronger visibility and control over identities, endpoints, and cloud application access—without introducing unnecessary friction for users. With a globally distributed workforce and a mix of managed and unmanaged devices accessing sensitive applications, Iyuno needed to move beyond perimeter‑based security toward a more context‑aware, Zero Trust–aligned model.

Key priorities included:

• Assessing and validating the existing Microsoft 365 security posture, including Entra ID configuration, enterprise applications, and Secure Score.
• Restricting risky access to applications and data through session‑based controls and Conditional Access policies.
• Evaluating Microsoft Defender for Endpoint in Active Mode through a controlled proof of concept before broader deployment.
• Improving endpoint and cloud app threat detection while maintaining operational continuity across regions.

This approach allowed Iyuno to make informed security decisions based on real production behavior, rather than theoretical designs.

The Thought Process: Targeted Security, Measured Risk

Iyuno and Ravanty aligned early on a key principle: effective security must be tested in real conditions but introduced in a controlled and reversible manner. Rather than deploying sweeping policies across the organization, the engagement emphasized validation, piloting, and evidence‑based decision‑making.

Ravanty guided Iyuno through its IDARE implementation framework:

• Ideate: Align on security goals, risk tolerance, and success criteria.
• Discover: Perform deep discovery across Entra ID, Intune, Defender, and enterprise applications.
• Architect: Design cloud app and endpoint security architectures aligned to Iyuno’s business workflows.
• Rollout: Deploy Defender and Conditional Access controls into production with limited scope.
• Emerge: Transfer knowledge, review results, and define a forward‑looking security roadmap.

This phased approach ensured security improvements were both technically sound and operationally practical.

The Solution

Threat Protection and Endpoint Security Enablement with Microsoft Defender

Ravanty delivered a focused security engagement centered on Microsoft’s Defender platform, integrating identity, endpoint, and cloud app protection into a cohesive control plane. Rather than treating each tool independently, the solution emphasized signal correlation, session control, and context‑aware enforcement.

The engagement combined production deployment with proof‑of‑concept testing—giving Iyuno both immediate security improvements and the data needed to evaluate long‑term adoption.

Technical Readiness: Identity, Endpoint, and Cloud App Security

Identity and Access Security

Ravanty began by validating Iyuno’s Microsoft Entra ID configuration, including authentication methods, Conditional Access policies, and enterprise application integrations. The team reviewed up to ten Entra‑integrated applications, focusing on SSO configuration and access controls.

Key outcomes included:

• Implementation of risk‑based and application‑specific Conditional Access policies.
• Session‑aware access controls to restrict authentication from risky sign-ins, risky locations, non‑compliant devices, and suspicious IP conditions.
• Policy validation using report‑only and pilot deployment models before broader enforcement.

This ensured Iyuno could reduce identity‑based risk while maintaining application availability.

Endpoint Security with Microsoft Defender for Endpoint and Intune

As part of the engagement, Ravanty conducted a Defender for Endpoint proof of concept in Active Mode across a limited set of Windows and macOS devices. This allowed Iyuno to evaluate Defender’s effectiveness in real‑world conditions.

Implemented controls included:

• Windows and macOS device onboarding to Defender for Endpoint.
• Antivirus, attack surface reduction, web content filtering, and vulnerability baseline assessments.
• Integration between Intune and Defender to support device compliance and policy enforcement.

This approach gave Iyuno concrete evidence of Defender’s value before committing to a full production rollout.

Cloud Application Protection with Defender for Cloud Apps

Ravanty designed and deployed Defender for Cloud Apps session policies to control how users interact with applications—particularly when accessing resources from unmanaged devices.

Capabilities delivered included:

• Session controls to restrict actions such as download, upload, copy, and paste.
• Threat‑intelligence–driven authentication signals (e.g., impossible travel, suspicious IPs).
• Alert notification when newly discovered shadow IT apps are detected, specifically aimed at third-party AI app usage.
• Integration with Defender for Endpoint to unify endpoint and cloud app signals.

These controls allowed Iyuno to protect sensitive workflows without blocking access outright.

Human and Operational Impact

Throughout the engagement, Ravanty worked closely with Iyuno’s global IT and security leadership, including stakeholders across the US, EU, and APAC regions. Regular working sessions, pilot testing in production, and informal knowledge transfer ensured that security controls aligned with real-world operational needs.

By testing policies in limited scopes and reviewing outcomes collaboratively, Iyuno reduced deployment risk and increased confidence in future security decisions.

The Results

By the end of the engagement, Iyuno achieved:

• Deployment of Defender for Cloud Apps with session‑based access controls.
• Successful proof of concept for Microsoft Defender for Endpoint in Active Mode.
• Implementation of multiple Conditional Access policies aligned to risk and application context.
• Improved visibility into endpoint, identity, and cloud app security signals.
• A prioritized, phased roadmap for expanding security controls across the organization.

These outcomes positioned Iyuno to advance its Zero Trust journey with clarity and confidence.

Why Iyuno Chose Ravanty

Iyuno selected Ravanty for its ability to deliver deep Microsoft security expertise while respecting the realities of a global, production‑critical environment:

• Specialized Microsoft Security Expertise: Proven delivery across Defender, Entra, and Intune.
• Structured Delivery Framework: IDARE ensured disciplined execution and risk management.
• Production‑Aware Approach: Emphasis on pilot testing and reversible controls.
• Strategic Microsoft Alignment: Effective use of Microsoft security funding programs.
• Collaborative Engagement Model: Close partnership with Iyuno’s global IT and security teams.

A Foundation for Scalable Security Maturity

This engagement represents a major step in Iyuno’s broader security evolution. By validating tools in production, correlating signals across identity, endpoint, and cloud apps, and grounding decisions in measurable outcomes, Iyuno established a modern threat protection foundation that can scale globally.

With Ravanty as a trusted partner and Microsoft as the security platform, Iyuno is now well‑positioned to expand its security capabilities while maintaining agility across its global operations.
