What Is Privileged Access Management?
Privileged Access Management (PAM) is a security framework that controls and monitors access to your most sensitive systems, accounts, and data. Privileged accounts, including administrator accounts, service accounts, and any credential with elevated permissions, represent the highest-value targets for attackers. PAM ensures those accounts are tightly controlled, their use is logged, and access is granted only when it's actually needed.
The core principle behind PAM is least privilege: every user, system, and process should have only the minimum access required to do its job, and nothing more. When that principle isn't enforced, a single compromised credential can give an attacker broad access across your environment.
Why Privileged Accounts Are the Biggest Risk
Most major breaches involve compromised privileged credentials. Attackers don't need to break through your perimeter if they can steal an admin account and walk in the front door. Inside your environment, privileged accounts can move laterally, access sensitive data, disable security controls, and cover their tracks.
The threat isn't only external. Employees, contractors, and vendors with elevated access can misuse it intentionally or accidentally. Without PAM controls in place, there's often no way to know what privileged accounts exist, who is using them, or what they're doing.

What PAM Controls
Effective PAM goes beyond simply restricting who can log in. It covers the full lifecycle of privileged access: discovering accounts, vaulting credentials, enforcing time-limited access, monitoring sessions, and producing audit evidence. STACK manages that lifecycle on your behalf.
Credential Vaulting
Privileged credentials are stored in a secure vault rather than shared informally or stored in spreadsheets. Access to the vault is controlled, logged, and time-limited.
Least Privilege Enforcement
User and system permissions are scoped to the minimum required for each role, reducing the blast radius if any account is compromised.
Session Monitoring
Privileged sessions are recorded and monitored in real time, providing a complete audit trail of what was accessed and what actions were taken.
Just-in-Time Access
Elevated permissions are granted only when needed and automatically revoked when the task is complete, eliminating standing privileges that expand your attack surface.
Audit and Reporting
Detailed logs of privileged account activity support compliance audits, internal reviews, and incident investigations with a clear chain of evidence.
Account Discovery
Privileged accounts you don't know about are the ones most likely to be exploited. PAM starts with a full inventory of every elevated account across your environment.
PAM and Compliance
Most major compliance frameworks require controls around privileged access. CMMC Level 2 includes specific requirements for limiting and monitoring privileged account use. HIPAA requires access controls and audit logs for systems that touch protected health information. PCI DSS restricts access to cardholder data environments and mandates monitoring of all administrative access.
PAM directly addresses these requirements by producing the audit evidence assessors look for: who had access, when they used it, what they did, and how access was revoked. Without those controls in place, demonstrating compliance is difficult even if your intent is sound.
How STACK Manages PAM
PAM isn't a product you install and walk away from. It requires ongoing management: accounts change, roles shift, vendors come and go, and access needs evolve. STACK handles the configuration, enforcement, and monitoring so your privileged access controls stay current without adding to your team's workload.
Discovery and Inventory
We identify all privileged accounts across your environment, including service accounts and shared credentials that often go untracked.
Policy Configuration
Access policies are configured to enforce least privilege, time-limited access, and approval workflows appropriate to each role and system.
Ongoing Monitoring
Privileged sessions are monitored continuously. Anomalous behavior triggers alerts so potential misuse is caught quickly rather than discovered after the fact.
Access Reviews
Regular reviews ensure privileged access stays aligned with current roles. Accounts for departed employees, former vendors, or changed responsibilities are identified and removed.
Part of a Broader Security Program
PAM is included in STACK's Managed Service Advanced tier alongside MXDR, SIEM, MFA, and vulnerability management. These controls work together: PAM limits what privileged accounts can do, MXDR watches for misuse, and SIEM retains the logs that prove controls are working.
If you're working toward CMMC certification, SOC 2, or another framework that requires documented access controls, PAM is one of the foundational pieces. STACK can help you build toward compliance rather than retrofit controls after the fact.
Ready to Get Your Privileged Access Under Control?
If you're not sure what privileged accounts exist in your environment or how they're being used, that's the right place to start. STACK can assess your current access posture, identify gaps, and implement controls that fit your environment and compliance requirements.
A Security Risk Assessment gives both of us a clear picture of your exposure before any commitment.
