Privileged accounts are the highest-value target in any environment, and PAM is the discipline built to protect them. Here's how it works, where its models differ, and where it stops.
When attackers breach an organization, they're rarely after the account they land on. They're after the accounts that account can reach: the domain admin, the database root, the identity provider console, the service account with write access to everything. Privileged accounts are the difference between an incident and a catastrophe, which is why they're the most consistently targeted asset in credential theft, phishing, and ransomware campaigns.
Privileged access management (PAM) is the security discipline built around this reality. It exists to answer four questions continuously: which accounts hold elevated access, who can use them, what are they doing with that access, and how quickly can it be taken away.
This guide covers what PAM is, the types of privileged accounts it governs, its two core operating models (PASM and PEDM), how break glass accounts fit into a locked-down environment, implementation best practices, and the honest boundary: where classic PAM stops, and what governs privileged access beyond it.
What Is Privileged Access Management?
Privileged access management is the set of controls, processes, and tooling that secures accounts with elevated permissions: the ability to change configurations, access sensitive data, manage other users, or administer systems. PAM works by discovering privileged accounts, vaulting and rotating their credentials, brokering and monitoring their use, and enforcing that elevated access is granted deliberately rather than held by default.
The distinction from identity and access management (IAM) is scope and depth. IAM governs all identities and their access to all resources. PAM concentrates on the small subset of access where compromise is most damaging, and applies proportionally heavier controls: credential vaulting, session recording, approval workflows, and time-bound elevation that would be impractical to apply to every login.
The underlying logic is risk concentration. A standard user account compromise exposes what that user can see. A privileged account compromise can expose the environment. PAM allocates control effort accordingly.
Types of Privileged Accounts
PAM programs typically govern several distinct account categories, each with a different risk profile:
Local administrative accounts. Admin access scoped to a single host or instance. Individually low-blast-radius, collectively dangerous, because local admin credentials are frequently reused across machines.
Domain administrative accounts. Elevated access across all workstations and servers in a domain. The highest-value target in most environments; a compromised domain admin is functionally a compromised environment.
Service accounts and non-human identities. Accounts used by applications, scripts, and integrations to talk to systems and to each other. They typically carry broad scopes, static credentials, and no natural owner, which makes them the largest unmonitored privilege surface in most organizations.
Application and database accounts. Accounts that applications use to access databases, run batch jobs, or call other applications, often with credentials embedded in code or configuration.
Emergency (break glass) accounts. Deliberately maintained high-privilege accounts reserved for scenarios where normal access paths fail. Covered in depth below, because they're the one category where PAM intentionally tolerates standing privilege.
SaaS application admin roles. Super admins, workspace owners, and elevated roles inside SaaS applications. Structurally privileged accounts, but historically outside the scope of classic PAM tooling, which is the gap addressed at the end of this guide.
How PAM Works: The Core Capabilities
Discovery. Continuous identification of privileged accounts across the environment, including the ones nobody documented: forgotten local admins, orphaned service accounts, and admin roles created outside the process. Discovery is foundational because every subsequent control only applies to accounts the PAM program knows about.
Credential vaulting and rotation. Privileged credentials are stored in an encrypted vault rather than known to users, checked out for use, and rotated automatically after each use or on schedule. Vaulting breaks the link between "knowing a password" and "having permanent access," and rotation limits the useful life of any stolen credential.
Session brokering, monitoring, and recording. Privileged sessions are established through the PAM system rather than directly, so activity can be monitored in real time, recorded for forensics, and terminated mid-session if something looks wrong.
Elevation and approval workflows. Requests for elevated access are evaluated against policy or routed to approvers, granted for bounded windows, and revoked automatically. This is where PAM converges with just in time access: the mechanics of on-demand, time-bound elevation are covered in full in our JIT access guide.
Audit and reporting. Every privileged access event, from checkout to revocation, is logged centrally. This record is both the forensic trail for incident response and the evidence base for SOX ITGC, SOC 2, ISO 27001, PCI DSS, and HIPAA audits, all of which require demonstrable control over privileged access.
PASM vs PEDM: The Two PAM Operating Models
Gartner splits PAM tooling into two complementary models, and the distinction matters when evaluating what a given tool actually does.
PASM (Privileged Account and Session Management) protects entire privileged accounts. Credentials live in the vault, users check out full account access for a session, the session is monitored and recorded, and credentials rotate afterward. PASM's strength is control over the account as a unit. Its weakness is granularity: a checked-out account grants everything that account can do. The user who needed to restart one service on a server checks out an account that can do anything on that server, and if the session credential leaks, the exposure is total for its duration.
PEDM (Privilege Elevation and Delegation Management) works at the level of individual privileges rather than accounts. Users operate from their standard accounts, and specific elevated rights are granted to that account, for specific actions, for a bounded time. A user gets the right to run a particular administrative command, or install approved software, or modify a specific configuration, without ever holding the full admin account.
PEDM has three practical consequences worth understanding:
It shrinks the admin account population. With PEDM, system administrators don't need dedicated always-on admin accounts. They work from standard accounts and receive elevation when a task requires it, which directly reduces the number of standing privileged accounts an attacker can target. This is PAM's main contribution to a zero standing privilege posture.
It contains lateral movement. Because elevation is scoped to specific actions and expires automatically, a compromised session yields a narrow, time-limited capability rather than a full admin credential. The attacker who intercepts a PEDM-elevated session can do one thing, briefly, instead of everything, indefinitely.
It enforces least privilege at task granularity. Role-based access defines what a role can hold; PEDM refines it to what a task requires. Application control (allowlisting what can run and under which conditions) and endpoint privilege management (removing local admin rights and elevating per-application) are the standard PEDM capabilities that implement this on workstations and servers.
Mature PAM programs run both models: PASM for the accounts that must exist as accounts (root, domain admin, break glass), PEDM to eliminate the need for standing admin accounts everywhere else.
Break Glass Accounts: The Sanctioned Exception
Everything above pushes in one direction: fewer standing privileges, more controls between users and elevated access. Break glass accounts are the deliberate exception, and getting them right matters precisely because they cut against every other control.
A break glass account is a pre-provisioned, highly privileged account reserved for emergencies where normal access paths fail: the identity provider is down and nobody can authenticate, an attacker has locked administrators out by changing security settings, or an MFA outage has stranded the entire IT team outside the systems they need to fix. In these scenarios, the controls that protect the environment on a normal day are the same controls preventing its recovery. Break glass is the escape hatch.
The design challenge is that a break glass account must work when everything else doesn't, which means it must be exempt from the dependencies that could fail: it's typically excluded from federated SSO, conditional access policies, and MFA methods that rely on the systems being recovered. An account with standing full privileges and reduced authentication requirements is exactly what PAM exists to eliminate, so every exemption needs a compensating control:
Exempt from phone-based MFA, protected by phishing-resistant hardware. The right pattern is not "no strong authentication" but "authentication with no external dependencies": FIDO2 hardware keys stored securely, or long, randomly generated credentials split between separately secured vaults so that no single person can use the account alone.
Excluded from conditional access, compensated by alerting. Any authentication event on a break glass account should page the security team immediately. These accounts are used a handful of times a year at most; every sign-in is either a drill or an incident.
Standing privileges, offset by scarcity and scrutiny. Maintain the minimum number needed for redundancy (two is the common pattern, in case one fails), assign named ownership, document exactly which scenarios justify use, and log every action taken during a break glass session for post-incident review.
Untested equals broken. Validate break glass accounts on a schedule (quarterly is typical): confirm the credentials work, the privileges are intact, the alerting fires, and the people who would need them under pressure know where they are and how to use them. An emergency account discovered to be non-functional during an actual emergency is worse than not having one, because the recovery plan assumed it.
Framed against the rest of this guide: break glass is what "100% zero standing privilege" realistically rounds down to. The goal is not zero exceptions, it's zero unexamined exceptions.
Best Practices for a PAM Program
Discover before you control. Start with a complete inventory of privileged accounts, human and non-human, documented and forgotten. The accounts outside the inventory are the ones attackers find first.
Eliminate standing privileges where possible, vault the rest. Use PEDM and JIT elevation to remove the need for always-on admin accounts, and put the accounts that must persist (break glass, root, critical service accounts) under vaulting, rotation, and session monitoring.
Enforce least privilege at task level, not just role level. Roles define the ceiling of what's grantable; elevation policies should grant only the specific rights a task requires, for only as long as it requires them.
Separate accounts from duties. No administrator should perform routine work from a privileged account, and no single account should combine privileges that create a conflict of interest. Standard account for daily work, elevation for administrative tasks.
Monitor sessions, alert on anomalies. Privileged activity outside approved windows, from unexpected locations, or on break glass accounts should generate immediate signal, not a log entry someone reads next quarter.
Automate the lifecycle. Provisioning, rotation, expiry, and revocation of privileged access should be system-enforced. Every manual step in the privileged access lifecycle is a step that will eventually be skipped.
These practices cover infrastructure-layer PAM. For the governance-layer practices that apply above the credential, identifying privilege as data, catching dangerous combinations, continuously shrinking standing access, see privileged access management best practices for 2026.
Where Classic PAM Stops: The SaaS Admin Layer
PAM tooling grew up around infrastructure: servers, databases, network devices, domain controllers. Vaults, session recording, and endpoint privilege management are built for that layer, and vendors like CyberArk, BeyondTrust, and Delinea remain the right answer for it.
See how these compare against the rest of the category in the 8 best PAM tools in 2026."
This is really a split between two types of privileged access management software, credential security and access governance. See the two types of privileged access management software for the full breakdown of what each one does and doesn't cover.
But a structurally identical privilege problem now lives somewhere those tools don't reach: inside SaaS applications. Workspace super admins, billing owners, users with permission to manage other users, elevated roles granted for a migration and never removed, integration tokens with admin scopes. These are privileged accounts in every meaningful sense, with the same risk profile (high blast radius, standing by default, invisible to review) and none of the classic PAM coverage, because there's no server to broker a session to and no credential the vault can own.
This layer is governed differently: through visibility into who holds elevated roles across the SaaS stack, policy-based and time-bound granting of those roles, and continuous review of whether elevated access is still justified.
This is the layer Zluri operates at, and its governance model has four moving parts.
Privilege as structured data. Zluri's discovery maps elevated roles and admin permissions across SaaS applications, human and non-human, including the ones granted directly in-app and never recorded anywhere central. Every discovered role carries a privilege indicator and every permission a privileged flag with a defined type (Create, Read, Update, Delete, Admin), so what counts as privileged is a checkable attribute on the entitlement, not a guess from a role's name.
Prioritization by what a grant actually permits. Per-grant threat scoring evaluates each application-user combination against the sensitivity of the data a scope touches and the operation it allows, which is what lets a program address the most dangerous standing SaaS privileges first rather than treating hundreds of admin grants as equally urgent.
Elevation that expires by default. The Access Duration field on Access Requests, paired with an automatically executing Deprovisioning Playbook, applies the JIT model to SaaS privileges: elevated roles requested through the App Catalog or Slack, granted against pre-approved policies or routed to approvers with full context, and reverted automatically to baseline when the window closes.
Review on its own cycle. Access Reviews scoped specifically to privileged access, fed by usage signals and peer comparison, continuously verify that elevated SaaS access still maps to a current, justified need, and catch the standing admin roles that shouldn't exist anymore.
Zluri is not a vault and doesn't replace infrastructure PAM. The two address different layers of the same principle: PAM tools govern privileged access to infrastructure, Zluri governs privileged access inside the SaaS applications where an increasing share of the business actually runs. For the complete breakdown of that governance layer, from privileged flags and approver insights through multi-level reviews and combination detection, see how Zluri handles privileged access management.
Frequently Asked Questions
What is the difference between PAM and IAM?
IAM (identity and access management) governs all identities and their access to all resources: authentication, SSO, provisioning, and general access control for every user. PAM is the specialized subset focused on elevated access, applying heavier controls (vaulting, session recording, approval-gated elevation) to the small population of accounts where compromise is most damaging. PAM operates within an IAM strategy, not instead of one.
What is the difference between PASM and PEDM?
PASM (privileged account and session management) protects whole privileged accounts: credentials are vaulted, checked out for monitored sessions, and rotated afterward. PEDM (privilege elevation and delegation management) grants specific elevated rights to standard accounts for specific tasks and time windows, eliminating the need for standing admin accounts. PASM controls the accounts that must exist; PEDM reduces how many must exist.
What is a break glass account?
A break glass account is a pre-provisioned emergency account with high privileges, reserved for scenarios where normal access paths fail: identity provider outages, MFA system failures, or attackers locking administrators out. It's deliberately exempted from dependencies like SSO and conditional access so it works when they don't, and those exemptions are offset by compensating controls: phishing-resistant hardware authentication or split credentials, sign-in alerting, strict usage documentation, and periodic testing.
How does PAM relate to just in time access and zero standing privilege?
Zero standing privilege is the target state (no permanent elevated access), just in time access is the granting mechanism (on-demand, time-bound elevation with automatic revocation), and PAM is the discipline and tooling that applies both to privileged accounts, alongside controls like vaulting and session monitoring for the privileged access that must persist. All three operate inside a zero trust architecture, which removes implicit trust from every request before these privilege-level controls even apply.
Does PAM cover SaaS application admin access?
Classic PAM tools largely don't. They're built for infrastructure privileges (servers, databases, network devices) via credential vaulting and session brokering, and SaaS admin roles don't fit that model: there's no credential to vault or session to broker for a workspace super admin. Elevated SaaS access is governed instead through identity governance controls: visibility into who holds elevated roles, time-bound granting, and continuous access review, which is the layer Zluri addresses.
Why do privileged accounts need separate management from regular accounts?
Because the cost of compromise is categorically different. A regular account exposes one user's access; a privileged account can expose systems, data, and every other account it administers. That asymmetry justifies controls (vaulting, session recording, justification-gated elevation) that would be disproportionate friction if applied to every login, but are proportionate for the accounts that can take down the environment.
