What is Privileged Access Management?
Privileged access management (PAM) is the practice of controlling the accounts that hold administrative power over a company's systems: domain and Microsoft 365 administrators, service accounts that run applications, and the vendor logins that reach in from outside. These accounts can change security settings, read any mailbox and wipe backups, so PAM treats them differently from an ordinary user login. The core idea is that nobody, including the IT team, should hold standing administrative rights that sit unused most of the day and available to anyone who steals the password.
In practice PAM combines a few mechanisms. Privileged credentials are stored in a vault rather than in a spreadsheet or a shared password manager, and the vault rotates them automatically after use. Administrators sign in to the vault with multi-factor authentication, check out the credential they need, and the session is recorded so there is a log of who did what and when. Standing admin rights are replaced with just-in-time access: a technician requests the role, holds it for a defined window, and it expires on its own. Service accounts get the same treatment, with passwords that change on a schedule and are never typed by a human.
For a small or mid-sized business, the accounts that matter most are usually a handful: the Microsoft 365 global administrator, the firewall login, the backup console, the line-of-business application admin, and whatever an outside IT provider uses to get in. If any one of those is shared, reused or left at a default, one phishing email can hand an attacker the whole environment. PAM shrinks that exposure to a short list of accounts that are vaulted and auditable, which is also what cyber insurers and regulators now ask about.
NetSys includes privileged access management in every managed IT agreement rather than selling it as an add-on. Engineers inventory every privileged account, move credentials into a vault with automatic rotation, enforce MFA on each privileged sign-in, replace permanent admin rights with time-limited activation through Entra ID, and keep session logs that can be handed to an auditor or an insurer on request. Details are on the privileged access management service page.
Why it matters for a small business
Most breaches at small companies end with an attacker holding an admin account, because that is where the damage gets done: backups get deleted and ransomware gets pushed to every machine. If your business has one shared admin password that three people know and your IT vendor also uses, that is the weakest point in the whole company. PAM fixes it with a short list of vaulted accounts, MFA on each, and a record of every use. It is also one of the first questions on a cyber insurance application.
Privileged Access Management (PAM): FAQs
What is the difference between PAM and PIM?
PAM controls how privileged accounts are used: vaulted credentials, rotated passwords, MFA on every privileged sign-in, and recorded sessions. PIM controls who is allowed to hold a privileged role and for how long, using eligible assignments that must be activated just in time and expire on their own. Most businesses need both. PIM decides that a technician may become a Global Administrator for two hours this afternoon; PAM makes sure the credentials involved are protected and the session is logged. In Microsoft 365, Entra ID PIM handles the role side and a vault handles the credential side.
Does a small business need privileged access management?
Yes, if anyone holds an administrator login, which is every business with Microsoft 365 or a server. Small companies tend to have fewer privileged accounts than large ones, which makes PAM easier to put in place, and the exposure is the same: one stolen admin password gives an attacker the ability to disable security tools and delete backups. A small business can cover the basics with a vault, MFA on admin accounts, separate admin and daily-use logins, and just-in-time roles in Entra ID, all of which fit inside a managed IT agreement.
Is PAM required for cyber insurance?
Many cyber insurance applications now ask directly whether privileged accounts are protected by MFA, whether admin and standard user accounts are separated, and whether privileged access is logged. Carriers word the questions differently, and a no answer can raise the premium or exclude coverage for certain losses. PAM is the practical way to answer yes with evidence, since it produces the vault records and session logs an underwriter may ask to see after a claim.
