What is Identity and Access Management (IAM)?

Identity and Access Management (IAM) is often confused with Privileged Access Management (PAM); however, IAM governs general identity and access controls, while PAM focuses specifically on privileged account management. Both are essential components of IT security strategies for enterprises and SMBs alike, especially for functions like authorization, authentication, and user activity monitoring. Continue reading to explore the details of what IAM is and why it matters.

Identity and Access Management (IAM) solutions provide comprehensive security frameworks to manage who can access which resources, when, and how, within an organization's IT infrastructure. The core features include:

• Authentication: Before accessing ERP, CRM, e-commerce platforms, or mobile apps, users must verify their identity using passwords, PINs, or biometric data. These authentication processes are essential for validating users and increasing security, especially when supported by multi-factor authentication methods.
• Authorization: Once authenticated, the system defines what resources or applications each user can access. This process ensures only authorized individuals gain access to sensitive data, thereby minimizing both internal and external threats.
• User Lifecycle Management: This covers access rights throughout the entire employee lifecycle—from onboarding to departure. Tasks such as account creation, role assignment, permission updates, and deactivation are centrally managed.
• Role-Based Access Control (RBAC): Access rights are assigned based on users’ roles and responsibilities, helping reduce unnecessary privileges and prevent potential security gaps.
• Centralized Identity Management: Manages all accounts, roles, and permissions from a single control panel—enhancing efficiency and reducing the risk of misconfigurations.
• Audit and Monitoring: Essential for tracking all login attempts, session data, and user activities. These logs play a critical role in detecting security incidents and ensuring regulatory compliance.
• Cloud and Hybrid Integration: IAM solutions work seamlessly with both on-premise and cloud-based systems, enabling secure access for remote employees, branches, and distributed teams.
• Multi-Factor Authentication (MFA) Support: Adds layers of protection beyond traditional passwords by requiring two or more verification factors.
  • 2FA: A second factor like an SMS code, app notification, or hardware key is required in addition to the password.
  • 3FA: Combines password and a second factor with biometric verification like fingerprint or facial recognition.
  • 4FA: Adds geo-location verification to confirm the user’s time and place during login.
  • 5FA: Incorporates behavioral biometrics such as typing rhythm, touch patterns, or device usage habits.

The answer to “what is Identity and Access Management” lies in its ability to manage authentication and authorization processes in a unified manner. IAM systems authenticate users through usernames, passwords, biometrics, or MFA methods, then assign access permissions based on pre-defined rules. These systems store credentials in a centralized identity repository and govern access through organizational policies. Moreover, cloud-based IAM solutions enable single sign-on (SSO) across not just internal apps, but also SaaS platforms, web apps, and mobile services.

IAM solutions go beyond cybersecurity—they also enhance operational efficiency and user experience. Their applications are vast: from large corporate networks and SMBs to e-commerce, banking, healthcare, and public sector digital services. Given their goal of enabling secure access for employees, customers, and partners, IAM tools are especially vital in cloud ecosystems, SaaS environments, mobile apps, and remote work setups.

Common areas where IAM solutions are implemented include:

• Corporate networks and internal systems
• E-commerce platforms and online retail
• Banking and financial applications
• Healthcare IT systems
• Public sector digital service portals
• Cloud-based software and SaaS offerings
• Mobile apps and remote work infrastructures

IAM (Identity and Access Management) and CIAM (Customer Identity and Access Management) both focus on identity management, but serve different purposes. IAM is primarily used to manage access for employees and partners within an organization. In contrast, CIAM handles the digital identities and access of external users such as customers. CIAM platforms emphasize customer experience, offering features like fast registration, social login, data privacy, and personalized access. In short, IAM enhances corporate security, while CIAM improves customer identity workflows and access control.

• IAM governs internal users and partners within an enterprise.
• CIAM is designed to manage customers' digital identities and access.
• CIAM improves UX with features like social login and quick sign-up.
• Privacy and personalization are key components of CIAM systems.
• While IAM focuses on internal security, CIAM optimizes customer engagement and identity workflows.

IAM and PAM play critical roles in cloud-based security solutions like IPSaaS, WAFaaS, FWaaS, and Vulnerability Management. Their integrations are outlined below:

• Firewall as a Service (FWaaS): IAM and PAM enhance firewall protections by preventing unauthorized access to network traffic.
• Web Application Firewall as a Service (WAFaaS): IAM and PAM integrate with WAFs to create robust barriers against web-based attacks.
• Intrusion Prevention System as a Service (IPSaaS): IPS solutions detect threats and, with IAM and PAM support, enable rapid response to incidents.
• Antivirus: IAM and PAM-backed antivirus tools are critical to protecting against malware threats.
• Vulnerability Management: These solutions, when integrated with IAM and PAM, proactively identify and mitigate security gaps—strengthening overall cyber posture.
