Discover who can compromise Tier 0
Identify the accounts, groups, service identities, and systems with direct or indirect control over Tier 0. Uncover lower-tier and unclassified identities with privileges that create risk.
Tiering & Segmentation
Protect critical assets with identity tiering
Find the access that breaks tier boundaries and exposes critical assets. Prioritize targeted fixes, verify isolation and catch new violations as your environment changes.
Limit attacker movement with identity tiering
Identity tiering separates accounts and systems by what they can control. Tier 0 holds the keys to your environment, from domain controllers to privileged roles in Microsoft Entra ID.
Lower tiers must not control higher tiers, and privileged credentials must stay protected from exposure on less trusted systems.
Nested groups, delegated permissions and service accounts can create attack paths across those boundaries, allowing a compromised identity to reach more privileged systems.
Put your identity tiering model into practice
Reveal access that crosses tier boundaries, prioritize the changes that strengthen isolation and coordinate remediation through governed workflows.
Trace the access that breaks tier boundaries
Compare your intended tiers with actual access across all Tiers. Trace permissions, nested groups and delegated rights to pinpoint where isolation breaks down.
Close more attack paths with fewer changes
Identify chokepoints that expose Tier 0 and prioritize targeted permission changes. A single fix can eliminate millions of attack paths.
Classify identities and automate remediation
Use built-in Tier 0 classification, manual assignment, and tagging workflows to assign identities to tiers. Remediate findings with prebuilt or custom workflows, with approval for sensitive changes.
Establish identity tiering in months instead of years
Time saved
12–24 months → 3–6 months
Estimated tiering project duration with Saporo. Reduce manual privilege mapping, accelerate remediation, and verify isolation throughout delivery.
Limit the impact of a compromised identity
Find the hidden access that lets a compromised account threaten Tier 0. Prioritize changes that remove the most attack paths and verify the reduction in exposure.
- Uncover indirect control over Tier 0
- Address shared paths with fewer changes
- Measure the exposure each fix removes
Accelerate delivery with less manual work
Give architects a clear view of effective privilege and a prioritized remediation plan. Spend less time reconstructing access relationships and more time establishing isolation.
- Reduce manual discovery & classification
- Spot the permissions that need changing
- Automate fixes through workflows
Preserve the value of every remediation
New permissions and configuration changes can reopen paths you already closed. Daily checks surface new violations so your team can address drift and sustain its progress.
- Detect new cross-tier access
- Track isolation through 180-day trends
- Demonstrate risk reduction to leadership
Tiering & Segmentation Q&A
What teams ask about tiering and segmentation
Identity tiering groups accounts and systems by administrative role and privilege. Tier 0 contains the identities and infrastructure that control your identity environment. Separating tiers limits how far a compromise can spread.
Identity segmentation restricts privileged access between tiers. It removes attack opportunities that could turn a compromised account or service identity into control of critical systems.
Saporo combines built-in Tier 0 classification with your tier assignments. Graph analysis then reveals lower-tier or unclassified identities with access or attack paths to Tier 0.
Saporo identifies direct, inherited, delegated and transitive access that breaks tier boundaries across all Tiers, including access from unclassified identities. It traces access and attack paths through nested groups, delegated permissions, service accounts and GPOs across Active Directory, Entra ID and every connected identity source.
Scheduled analysis reveals new tier violations and access or attack paths reopened by permission or configuration changes, helping your team address drift and sustain isolation.
