Admin accountsMSP technician accountsCloud infrastructure accountsExternal-facing applicationsRemote access toolsAny MFA deployment is better than none, but phishing-resistant methods offer the strongest protection. Once privileged accounts are enforced, expand MFA to all users over the next 30 days. Doing so reduces the likelihood that compromised credentials lead directly to unauthorized access. 2. Implement privileged access management to control admin permissions: Least privilege is the second half of effective identity security. Even when a user successfully authenticates, they should only have access to the minimum resources required for their role. Privileged Access Management (PAM) helps enforce this by centralizing credential storage, eliminating shared administrative passwords, and controlling privilege elevation on endpoints.N-able Passportal helps teams vault and rotate privileged credentials automatically and integrate credential hygiene with Microsoft Active Directory. This reduces the risk of privilege creep, orphaned accounts, and long-lived passwords that attackers routinely exploit.For MSPs, centralized credential management prevents a compromised technician credential from granting access across dozens of client environments. For corporate IT teams, PAM reduces the likelihood that attackers can escalate privileges after gaining initial access. 3. Inventory every identity”, human, machine, and workload: You cannot protect the identities you do not know exist. Most environments have far more machine and service accounts than human users, and these non-human identities often carry higher privileges with far less scrutiny.A complete identity inventory should include:
Employees, contractors, and vendor accountsService accounts for scheduled tasks and automationAPI keys used in integrationsCertificates supporting encrypted communicationApplication and workload identities used in cloud-native environmentsMachine and workload identities need special attention because they rarely trigger alerts when abused. Attackers increasingly target them to escalate privileges quietly.Maintaining this inventory helps IT teams identify shadow identities, remove unnecessary permissions, and reduce pathways attackers use for lateral movement. 4. Establish continuous validation to detect compromise earlier: Credential compromise often goes undetected for months. Continuous validation helps reduce that window by monitoring identity behavior in real time, such as:
Impossible travel loginsSudden privilege escalationsActivity from unmanaged devicesUnusual authentication patternsUnexpected API usageModern identity attacks frequently blend automation, AI-driven phishing, and tactics that bypass traditional alerting. Continuous validation helps security teams catch these anomalies earlier and contain attacks before they spread.Tools such as Adlumin ITDR support identity threat detection by monitoring Microsoft 365 logins, detecting abnormal identity behavior, and automatically taking action based on severity. 5. Build zero trust foundations by combining identity, devices, networks, applications, and data: Identity security is the first pillar of Zero Trust, but it cannot operate in isolation. Strong authentication means little if endpoints are unpatched or privileges are overly broad. To reduce lateral movement and strengthen attack resilience, Zero Trust requires continuous verification across five domains:
Identity authenticate every user and entityDevices ensure endpoints meet security requirementsNetworks limit movement using segmentationApplications enforce granular permissionsData protect sensitive information at the access layerIdentity compromise often becomes dangerous because organizations have uneven maturity across these pillars. For example, enforcing MFA but allowing unmanaged endpoints still gives attackers footholds they can use after initial access.Tools like N-able N-central RMM help secure the device pillar by providing patch management, vulnerability scanning, and continuous endpoint monitoring. Cove Data Protection strengthens the data pillar by ensuring reliable recovery if identity compromise leads to ransomware or destructive activity. Building identity-driven attack resilience: Identity security is not a one-time implementation. It is a continuous process of enforcing stronger authentication, removing unnecessary privileges, validating each access request, and monitoring for misuse.A practical roadmap for IT and security teams includes:
- Enforce MFA for all identities, starting with privileged accounts.Deploy PAM to manage and secure administrative credentials.Document all identity types and remove or restrict unnecessary accounts.Monitor authentication behavior continuously to detect compromise early.Extend Zero Trust practices across devices, networks, applications, and data.
Taken together, these steps significantly reduce the likelihood that attackers can use valid credentials to gain broad access across your environment. They also help contain the impact when identity compromise does occur.Download the new 2026 State of the SOC report and get a data-driven playbook for resilience across identity, endpoint, cloud, network, and perimeter layers.
