What Is Entra ID?

Over 720,000 organizations worldwide rely on Entra ID for their identity and access management needs. This widespread adoption reflects its effectiveness in securing digital environments for businesses of all sizes.
Microsoft Entra ID uses a flat organizational structure, meaning it operates around a “tenant” system. Each tenant represents a dedicated instance of Entra ID designed specifically for an organization. This setup simplifies identity management compared to traditional, hierarchical systems like Active Directory.

Key features that enhance this streamlined structure include:

• Passwordless Authentication: Eliminates the need for traditional passwords by using biometrics, security keys, or authentication apps. This approach significantly lowers the risk of credential theft and phishing attacks while making it easier for users to log in securely.
• Conditional Access: This type of access control monitors user behavior, device health, and location to determine access permissions. For example, it can block login attempts from unfamiliar devices or suspicious locations, adding an extra layer of protection against unauthorized access.
• Device Management with Intune: Allows IT teams to remotely manage, monitor, and secure both company-owned and personal (BYOD) devices. This ensures that all devices accessing company data meet security standards and are regularly updated.

Key features of Entra ID:

• Multifactor Authentication (MFA): Relying only on passwords is risky, especially with so many cyber threats out there. MFA adds extra protection by asking for more than just a password. It might send a code to your phone, require a fingerprint scan, or ask for a security key. This extra step makes it much harder for hackers to get into accounts, even if they have a password.
• Single Sign-On (SSO): Logging into several apps every day can be annoying and time-consuming. SSO solves this by letting users log in once and access all their apps without needing to enter their passwords repeatedly. Whether checking emails in Microsoft 365 or using cloud storage, SSO makes work faster and easier.
• Privileged Identity Management (PIM): Not everyone in a company needs access to sensitive information. PIM helps control who can see or change important data by giving out special permissions only when needed. This limits the risk of misuse or security issues and keeps important systems safe.

At OTAVA, we help organizations maximize these features by offering tailored identity management solutions. Our expertise in Azure Identity Management (IAM) ensures that businesses can implement secure and scalable access controls.

Traditional Active Directory (AD) and Microsoft Entra ID may share the goal of managing user identities, but they function in very different ways. Active Directory was designed for on-premises environments, while Entra ID is built for the cloud. This distinction leads to several key differences in how they operate.
In a 2023 Forrester study, organizations using Entra ID reported a 240% ROI over three years. This statistic highlights the significant cost savings and efficiency improvements Entra ID provides compared to traditional identity solutions.

Local Bouncer vs. Global Security Guard:

Active Directory can be seen as a local nightclub bouncer. It checks IDs (user credentials) against a guest list (on-premises directory) and grants access if everything matches. However, Entra ID acts more like a global security guard managing multiple venues worldwide. It performs real-time security checks like geolocation tracking, device health monitoring, and compliance enforcement before letting users in.

At OTAVA, we help organizations bridge the gap between on-premises and cloud identity management. Our Azure Cloud Migration Services allow businesses to transition smoothly to cloud-based solutions like Entra ID, unlocking greater flexibility and scalability.

Microsoft Entra ID serves a wide range of users, each benefiting from its unique features:

• IT Administrators:Managing user access and keeping systems secure is a huge task, and Entra ID makes it easier. IT admins use it to control who can access certain apps and data, set up security policies likeConditional Access, and stay on top of compliance requirements. It streamlines their workload while strengthening security across the entire organization.
• Developers: Developers love Entra ID because it gives them the tools to build safer and smarter apps. With its APIs, they can easily add secure login options, like single sign-on (SSO) and multifactor authentication (MFA), into their apps. This means users can log in safely, and developers do not have to start from scratch when building security features.
• End Users: Most employees and partners do not even realize they are using Entra ID, but it is always working in the background. Whether they are logging into Microsoft Teams, sharing files on SharePoint, or using Dynamics 365, Entra ID silently handles their login and keeps their data safe.

At OTAVA, we tailor identity management solutions to fit every user group. Whether it is empowering IT teams with better tools or simplifying access for end users, we ensure seamless integration across business operations.

A Zero-Trust security model assumes that threats could exist both inside and outside an organization’s network. Entra ID plays a crucial role in enforcing this model through several robust features.

• Conditional Access Policies: These automatically block or grant access based on user risk levels, device health, and location.
• Risk-Based Authentication: Entra ID continuously assesses user behavior and flags suspicious activity.
• Geolocation Security: Users attempting to access company resources from unfamiliar locations are subject to additional verification steps.

At OTAVA, we prioritize Zero Trust security in our cloud solutions. Our 24/7/365 Azure Security Monitoring services complement Entra ID’s built-in protections, giving businesses a comprehensive security strategy.

Microsoft offers Entra ID in different licensing tiers to cater to diverse business needs:

• Free Tier: Provides basic user and group management, directory synchronization, and single sign-on for select applications.
• Premium P1: Adds advanced features like Conditional Access, hybrid identity support, and self-service password reset.
• Premium P2: Includes all P1 features plus identity protection, risk-based Conditional Access, and Privileged Identity Management.

Setting up Entra ID begins with creating a tenant, which involves registering a company with Microsoft Cloud services. The default domain (e.g., companyname.onmicrosoft.com) can be customized for branding and ease of use.
At OTAVA, we simplify this setup process through our Cloud Readiness Assessment and Azure Architecture & Design Services. We help organizations select the right licensing tier and configure their environment for maximum security and performance.
