IAM vs. PAM Similarities, Differences and How to Choose

The landscape of the corporate workplace changed dramatically post-pandemic when many companies were forced to go remote. This has brought to the forefront the question of how to manage the cybersecurity needs of companies with a dynamic structure where employees can access company infrastructure from anywhere in the world.

Identity and access management (IAM) and privileged access management (PAM) are solutions that companies are looking at as viable options for network security and network access management. Let’s look at what IAM & PAM are, their similarities and differences and the ways they help enhance network security.

What Is IAM (Identity and Access Management)?

Identity and access management (IAM) refers to the various protocols that are implemented for identifying, authenticating and authorizing users in general with unique digital identities. Because IAM focuses on authenticating and authorizing every user, it dovetails nicely with the zero-trust philosophy.

IAM solutions are deployable both on-premises and via the cloud and use one or more combinations of authentication protocols like digital certificates, single sign-on (SSO) and multi-factor authentication (MFA). Some of the most widely used IAM solutions are:

• Accounting, authorization, authentication (AAA) servers, also known as RADIUS servers
• OAuth Protocol authenticating indirectly using the credentials of an approved third-party application

What Is PAM (Privileged Access Management)?

Privileged access management (PAM) is essentially a subcategory of IAM that focuses on managing a certain subset of users who need access to sensitive/privileged resources. For example, employees in the HR team or IT department need access to some sensitive information to effectively function in their role, which otherwise is not needed by all employees.

With PAM, you can regulate the access level of users based on the group or team that they belong to, thus limiting access to critical information to only the users who require it to function in their roles.

IAM vs. PAM

IAM and PAM are sometimes used interchangeably, and though they are related, they are still different from each other. IAM solutions are designed to manage and monitor the network security of an entire organization; PAM manages access of specific users and machines that need special access to perform sensitive roles. Let’s see where these two technologies have similar functions and what features are unique to each protocol.

Similarities Between IAM and PAM

• Role-based access: Both solutions provide role-based access control (RBAC), which is considered an essential component of network security. With IAM and PAM, instead of access to the entire network, users only have access to the company information that is needed to perform their roles.
• Access to multi-factor authentication: Using two or more authentication protocols to verify a user or a machine before allowing access to the network is called multi-factor authentication (MFA). IAM and PAM both have the option to implement MFA. Along with credential-based and certificate-based authentication, you can enable protocols like biometrics, or OTP-based authentication. Passwordless mechanisms like QR codes, geolocation, IP addresses and even accessing user behavior to verify the authenticity of a user are some of the other popular authentication protocols that are used in MFA.
• Seamless monitoring/better network visibility: Both solutions allow constant monitoring of end-user activity that helps identify and address security issues immediately and in real time.
• Reporting: With IAM, companies can generate a comprehensive analytic report of user activity. PAM enables you to customize a report with detailed analytics. Almost every regulatory board requires some form of reporting. IAM and PAM help you comply with audit and reporting requirements for your regulatory boards.

Key Differences Between IAM and PAM

Though IAM and PAM solutions share similarities, there are some major differences that make each unique in their utility and scope. Here are some of the differences that can be seen between the two solutions.

Scope

The main difference between IAM and PAM is the scope of their focus.

• IAM broadly looks at the entire organization, authenticating and authorizing users in general. Its ultimate goal is to ensure that only employees can access anycompanyresource.
• PAM, in comparison, primarily focuses on restricting access to sensitiveresources by defining a narrow subset of users allowed to access said resources. Rather than worry about authentication/authorization on a general scale, it seeks to ensure certain privileged users are able to access restricted resources – and only the restricted resources they need to perform their roles.

Authentication Protocol Stringency

Another difference between the two approaches is the stringency of the authentication protocols involved.

• Although IAM applies to far more users, its general focus means it doesn’t require the same degree of stringency as PAM does.
• PAM’s goal of protecting the most sensitive resources means it needs to have extremely stringent authentication policies. Aside from authenticating and authorizing users, it must also look to provide a method of accounting. When critical resources are accessed by an authorized user, that user’s actions need to be recorded so any suspicious activity can be flagged and scrutinized.

Resources

• IAM tends to require a combination of authentication methods, such as SSO, MFA and digital certificates, calling for a much wider range of knowledge from your administrators.
• PAM requires a steeper investment. This is because it safeguards your organization’s most valuable assets. If your PAM policy is weak, the resulting data breaches could be critical.

IAM vs. PAM: Pros and Cons of Each Solution

IAM Pros

• Cloud and on-prem capabilities: IAM solutions work with both on-prem and cloud servers. Though there has been a general shift to the use of cloud servers because of the flexibility, there are still some companies that prefer to retain on-prem servers because they feel it gives them better control over physical servers. There are some organizations that like to continue using on-prem servers in conjunction with cloud servers. They may not want to retire these servers or are still in the process of migrating to a complete cloud infrastructure.
• Device management: With companies moving toward hybrid and remote work, the number of unmanaged devices is increasing. Handling network security for these devices becomes a tedious process if not managed well. A managed cloud RADIUS server allows companies to manage their network security by bringing the growing number of unmanaged devices under their umbrella. This flexibility helps companies to manage and control access with very little effort thus making it especially useful for the current dynamic workforce.
• Automation: IAM solutions allow companies to automate authentication and access management. Life before IAM saw IT teams manually creating profiles for each user to align individual user accounts and adjust their authentication methods to provide user/role-based access. With IAM, authentication and access management can be automated, thus eliminating the task of manual access management. For example, Cloud RADIUS can be configured to automatically revoke digital certificates from users who fail authentication for any reason.

IAM Cons

• Complicated implementation: Though IAM is widely used, its vast array of features sometimes makes it complicated to implement effectively. IAM solutions work best when used with digital certificates and a combination of single-sign-on (SSO) and multi-factor authentication (MFA). Using only one method can impact the efficiency of IAM as a network security solution.
• High IT expertise requirements: Because IAM works most optimally when multiple authentication types are used, implementing IAM effectively often requires your IT department to have varied expertise.

PAM Pros

• Tighter access control: PAM is designed to monitor and manage access to critical resources such as confidential employee information. Only the users that need access to the data to perform in their roles, like HR or system administrators, are allowed access to these resources.
• Multiple layers of security: Security protocols in PAM are very stringent. There are multiple layers of authentication protocols set up to not only grant access to a user but also to monitor any activity these users take, reporting and flagging the slightest anomaly. PAM allows real-time identity and access management which means user access can be granted or revoked dynamically in case of a breach.

PAM Cons

• Resource intensive: Role-based access management requires careful planning and mapping of levels of access for each department or group. Since the goal is to restrict access to sensitive resources, you’ll need to employ multiple authentication protocols, which requires lots of resources and time.
• User permission vulnerabilities: Utilizing PAM effectively also means needing to keep in mind all possible network vulnerabilities borne from user permissions. And the slightest lapse may have the potential to cause irreversible damage to a company. The quality of resources and strategy implemented to design these solutions are crucial determiners of their effectiveness.

Frequently Asked Questions

Is PAM the same as IAM?

No, privileged access management (PAM) and identity and access management (IAM) are not the same, though they are closely related. IAM focuses on managing digital identities and controlling user access across systems, while PAM specifically secures and monitors privileged accounts with elevated permissions. As organizations continue adopting cloud services and hybrid environments, PAM is increasingly becoming a critical layer within broader IAM strategies.

Is PAM part of IAM?

Yes, PAM is generally considered a specialized subset of IAM. IAM handles authentication, authorization and identity governance for all users, while PAM concentrates on protecting high-level administrative accounts that present greater security risks.

Why do organizations need both IAM and PAM?

IAM and PAM work together to create a stronger security framework. IAM ensures users have appropriate access to resources, while PAM adds additional protection for sensitive systems and critical accounts. With growing regulatory requirements and remote work environments, organizations are increasingly relying on both to support zero-trust security models.

Is PAM only used for cybersecurity?

While PAM is primarily a cybersecurity solution, it also supports compliance, operational accountability and risk management. Organizations use PAM to track privileged activity, reduce insider threats and meet industry regulations.

How does certificate-based authentication support IAM and PAM?

Certificate-based authentication strengthens both IAM and PAM by replacing passwords with digital certificates that verify a user or device’s identity. This reduces the risk of credential theft, phishing attacks and unauthorized privileged access. As organizations adopt zero trust security models and passwordless authentication, certificates are becoming an increasingly important component of modern identity and privileged access strategies.
