Complete Identity Visibility Without Complexity

The Challenge

Enterprises can't see their full identity landscape. Service accounts multiply unchecked, trust relationships span forests nobody mapped, and orphaned privileges accumulate in blind spots. When a breach happens, teams discover an attack surface they didn't know existed.

Our Solution

Forestall provides continuous, agentless discovery of every identity object, relationship, and privilege across multi-forest and hybrid environments. Without agents or elevated access, teams gain complete visibility into their identity landscape — including services like Exchange, DNS, ADCS, WSUS, and SCCM — turning unknown risk into mapped, measurable, and manageable posture.

Core Capabilities

A comprehensive set of identity discovery and mapping capabilities that work without agents, without elevated privileges, and across hybrid environments.

Identity Asset & Relation Mapping

Gain full visibility into identity objects, infrastructure services, and their interconnections to understand the true scope of your identity attack surface.

  • Evaluate related services such as Exchange, DNS, ADCS, WSUS, and SCCM to uncover hidden dependencies
  • Automatically identify and classify service accounts across your environment
  • Identify remnant credentials by analyzing active sessions and correlating them with identity context
Identity Asset & Relation Mapping

Hybrid Identity Discovery

Map every identity object across complex, multi-forest and hybrid environments without deploying agents or requiring administrative access.

  • Analyze multi-forest and hybrid identity environments without agents or admin privileges
  • Assess identity objects and their relationships across domains and forests
  • Enrich identities with contextual correlations for deeper analysis
Hybrid Identity Discovery

Privilege Assessment

Analyze identity privileges to identify excessive or unused rights, permissions, and privileges ensuring the principle of least privilege is maintained.

  • Detect excessive or unused rights and permissions across identity objects
  • Enforce the principle of least privilege with evidence-based privilege analysis
  • Identify local administrator privileges and elevated rights across domain-joined systems
Privilege Assessment

Identity Hygiene Assessment

Review and assess the health of your identity environment, identifying stale accounts, orphaned objects, and configuration violations.

  • Detect dormant privileged accounts, accounts with non-expiring passwords, and security misconfigurations
  • Identify orphaned objects and stale accounts that expand the attack surface unnecessarily
  • Pinpoint every identity hygiene issue that can be cleaned up or hardened to reduce risk

Real-World Use Cases

M&A Identity Due Diligence

Scenario: During a merger or acquisition, the security team needs to understand the identity posture of the target environment before integration begins.

How Forestall helps:

  • Deploy read-only connectors to the target environment without requiring admin access
  • Generate a complete identity object and privilege inventory within hours
  • Identify high-risk trust relationships and excessive privilege assignments
  • Produce a posture report documenting identity exposure before integration
Outcome: Security teams get full visibility into the target identity environment before any integration work begins, preventing inherited risk.

SOC Identity Inventory for Incident Response

Scenario: During a security incident, SOC analysts need to quickly understand which identities, privileges, and relationships are in scope for the compromised environment.

How Forestall helps:

  • Provide an always-current identity inventory with privilege context
  • Surface which accounts have administrative access and where
  • Map relationships between compromised objects and critical assets
  • Identify service accounts and session-based credential exposure
Outcome: SOC analysts reduce investigation time by having a pre-built identity map that shows exactly which accounts and paths are relevant to the incident.

Hybrid Migration Planning

Scenario: IT Operations is planning a migration from on-premises Active Directory to a hybrid cloud identity model and needs to understand the current identity landscape.

How Forestall helps:

  • Map all identity objects, trust relationships, and service dependencies
  • Identify service accounts and their dependencies across infrastructure services
  • Classify privilege tiers to understand which objects need priority migration attention
  • Detect stale and orphaned accounts that can be cleaned up before migration
Outcome: IT teams reduce migration risk by starting with a clean, well-documented identity inventory that accounts for all dependencies.

Continuous Identity Hygiene

Scenario: The security team wants to maintain ongoing visibility into identity sprawl and privilege creep as the environment evolves.

How Forestall helps:

  • Run continuous discovery to detect new identity objects and relationship changes
  • Track privilege tier changes and service account creation over time
  • Alert on new credential exposure paths and local administrator additions
  • Provide trend data showing identity posture improvement or degradation
Outcome: Teams shift from periodic audits to continuous identity monitoring, catching exposures as they emerge rather than after they are exploited.

Frequently Asked Questions

What identity environments does Forestall support?

Forestall supports hybrid identity environments including Active Directory multi-forest configurations and cloud identity systems. Current coverage includes widely deployed enterprise identity systems, with additional IAM provider support being expanded over time.

Does Identity Attack Surface Management require endpoint agents?

No. Forestall uses connector-based, read-only collection for identity discovery and posture analysis. There are no endpoint agents to deploy, manage, or maintain.

How quickly can teams achieve full identity visibility?

Most environments achieve complete identity discovery within 24 hours of connector deployment. The read-only approach means there is no change management or staging required before going live.

What level of access does the connector require?

Forestall is designed for least-privilege access and read-only integrations. The connector does not require domain admin or equivalent elevated privileges to perform identity discovery and analysis.

How does this differ from traditional identity governance tools?

Traditional IGA tools focus on lifecycle management—provisioning and deprovisioning. Forestall focuses on posture—discovering what actually exists, how it is configured, and where the exposures are. The two are complementary.
