Privileged Access Management: Why PAM Is the Last Line of Defence

Privileged Access Management: Why PAM Is the Last Line of Defence

Look at the post-breach forensics from any significant enterprise incident in the last five years. Somewhere in the attack chain, there is a privileged account.

An admin credential harvested from an endpoint. A service account with domain admin rights that was set up in 2019 and never reviewed. A local administrator password identical across 400 workstations.

Attackers don't need to break your perimeter. They need to find one privileged account. Then the network is theirs.

Privileged Access Management (PAM) is the discipline — and the technology — that closes this gap. In 2026, for any organisation operating serious IT infrastructure, it is not optional.

What PAM Actually Is

PAM is not a password manager. It is a continuous framework for controlling, monitoring, and auditing access to your most sensitive systems and accounts. It covers:

  • Privileged account discovery — you can't protect what you don't know exists
  • Credential vaulting — privileged passwords stored, rotated, and checked out on demand
  • Just-in-Time (JIT) access — elevated access granted for a task, then automatically revoked
  • Session recording — every privileged session recorded and searchable
  • Anomaly detection — alerts when privileged accounts behave outside normal patterns

Why Most Organisations Get PAM Wrong

Partial deployment. PAM is deployed for obvious systems, but developer workstations, cloud consoles, and SaaS admin accounts remain outside scope. Attackers find the gap.

Standing admin rights still exist. The original admin accounts — created before PAM was deployed — still have permanent domain admin rights. The vault is beside the door left open.

Service accounts are ignored. Service accounts frequently have broad permissions and passwords that never rotate. Service account compromise is one of the cleanest paths to lateral movement in any enterprise.

What Good PAM Looks Like

Zero standing privilege. No user should have permanent admin access to any production system. Microsoft Entra PIM implements this for cloud workloads. CyberArk, BeyondTrust, and Delinea handle on-premises and hybrid environments.

Automated credential rotation. Privileged passwords rotate after each session. No static credentials. No shared passwords.

Full session recording. Every privileged session recorded, timestamped, and indexed for compliance and forensics.

Service account governance. Service accounts inventoried, classified by risk, and subject to regular review with scoped permissions.

The Blast Radius Question

The real value of PAM is not just preventing initial compromise — it's limiting the blast radius when something does go wrong. With mature PAM: a compromised credential gives time-limited, scoped access; session recording enables forensic reconstruction; anomaly detection surfaces the compromise early.

Without PAM, a single compromised admin account can mean complete environment takeover in hours.

Starting Point for 2026

  1. Inventory all privileged accounts across AD, Entra ID, cloud consoles, network devices, databases
  2. Vault and rotate credentials for the highest-risk accounts immediately
  3. Implement JIT access for domain admin and production system access
  4. Enforce MFA on all privileged access — no exceptions
  5. Record all privileged sessions — start with the highest-risk systems
