Your identity environment — the user accounts, permissions, group memberships, and authentication policies in Active Directory, Azure AD, or Entra ID — accumulates risk over time. Employees leave but their accounts stay active. Someone gets admin rights for a project and never has them revoked. MFA gets enabled for some users but not others. A service account is set to never expire its password. None of these are attacks. They’re just drift — and they’re exactly what attackers look for when they get inside a network. ISPM is the discipline that finds and fixes this before it becomes a problem.

ISPM stands for Identity Security Posture Management. It’s a continuous assessment of your identity configuration — not looking for active attacks (that’s ITDR), but auditing the underlying settings, permissions, and policies that determine how hard or easy it would be for an attacker to move through your environment if they got in.

Think of ISPM as the regular audit of your identity hygiene. Where ITDR is your alarm system, ISPM is checking whether the doors and windows are locked.

What ISPM Looks For

Stale and orphaned accounts. Former employees, contractors, and service accounts that are still active in the directory. Every active account is a potential entry point. ISPM continuously identifies accounts that haven’t been used recently and flags them for review or deactivation.

Excessive permissions and privilege creep. Users accumulating rights over time — admin access granted for a one-time task that was never revoked, service accounts with broader permissions than they need, group memberships that no longer reflect current job functions. ISPM maps permissions against what’s actually needed.

MFA coverage gaps. Multi-factor authentication is one of the highest-value security controls available. ISPM identifies which accounts and applications have MFA enforced and which don’t — including privileged accounts, which should always have MFA and frequently don’t.

Password policy weaknesses. Accounts with passwords set to never expire, weak password policies in Active Directory, accounts that haven’t had a password change in years. ISPM surfaces these configurations.

Misconfigured authentication policies. Legacy authentication protocols that should be disabled, Conditional Access policies with gaps, service principals with excessive API permissions in Entra ID. These are technical but they’re real attack vectors that ISPM is designed to surface.

Shadow admins. Accounts that have effective administrative rights through indirect paths — nested group membership, delegated permissions, or role assignments that aren’t obvious from the surface. Attackers actively look for these.

ISPM vs. ITDR — Understanding the Difference

ITDR and ISPM address identity security from two different angles. ISPM is proactive and posture-focused — it continuously audits your identity configuration to find weaknesses before they’re exploited. ITDR is reactive and detection-focused — it monitors your identity systems for signs of active attack.

A complete identity security strategy needs both. ISPM makes sure your environment is configured to limit what an attacker can do if they get in. ITDR makes sure you’ll know when someone is trying. They’re complementary, not competing.

Why Identity Drift Happens

Nobody intends to leave stale accounts active or accumulate excessive permissions. It happens because identity management is an ongoing operational task that gets deprioritized. A new employee gets added, a departing one gets missed in the offboarding checklist. An admin right gets granted in a hurry and never reviewed. A password policy exception is made and never reversed.

Over time, in any organization that’s been operating for more than a few years, the gap between what the identity environment looks like on paper and what it actually looks like in practice gets wide. ISPM makes that gap visible on a continuous basis instead of waiting for a quarterly audit — if there’s an audit at all.

What ISPM Looks Like in Practice for a Tallahassee Business

For a 25–100 person business in Tallahassee using Microsoft 365 and Azure AD, ISPM isn’t necessarily a standalone platform — it’s a set of practices and tools that get incorporated into how your identity environment is managed. Regular reviews of active accounts, permission audits on a defined schedule, Conditional Access policy reviews, enforcement of MFA across all privileged accounts.

ABS builds identity hygiene practices into our managed IT engagements. If you’re not sure what your current identity posture looks like — how many stale accounts you have, which admin accounts don’t have MFA, where permissions have drifted — that’s something we can assess and address as part of a managed IT relationship.
