Introducing BloodHound Enterprise On-Premises: Why On-Prem Identity Attack Path Management Still Matters in a Cloud World

TL;DR : BloodHound Enterprise on-premises brings enterprise-grade identity attack path management to air-gapped, classified, and highly regulated environments. It uses the same engine as our SaaS solution while keeping all identity data within your security boundary.

Cloud adoption has transformed how organizations deploy and scale security tools. For many use cases, SaaS delivers speed, simplicity, and operational efficiency. But for organizations operating in highly sensitive environments, the calculus is different.

For the first time, organizations in these highly sensitive environments have full visibility using BloodHound Enterprise on-premises to identify all their identity attack paths and eliminate them programmatically based on their criticality. Available to be deployed on bare metal or with containerization, BloodHound Enterprise on-premises uses the same engine as our SaaS solution while keeping all identity data within your security boundary.

What do these highly sensitive environments look like? Consider defense contractors managing Controlled Unclassified Information, financial institutions processing transaction data under strict regulatory oversight, critical infrastructure operators protecting operational technology networks, or government agencies working with classified systems.

In these environments, SaaS-based security tools face significant barriers to adoption. Internal risk policies may prohibit sending sensitive data to third-party processors. Regulatory frameworks like GDPR, NIST 800-53, NIST 800-171, or DoD security requirements impose restrictions that make cloud connectivity impractical or impossible. Air-gapped networks and classified environments eliminate external connectivity entirely.

Yet the security challenges in these environments are no less severe. The problem remains the same: users, privileges, misconfigurations are chained together and exploited all the same whether your systems are in a regulated or sensitive environment or not. However, the toolsets available to defenders charged with mitigating these risks are more often SaaS based.

Understanding Identity Attack Path Management (APM)

Identity attack path analysis reveals how effective privilege and identity relationships create exploitable paths that bypass current security practices and tools.

Identity APM operates on a different principle than conventional security silos, such as Privileged Access Management (PAM), Identity Governance and Administration (IGA), or Identity Threat Detection and Response (ITDR). It doesn’t just analyze permissions, vulnerabilities, or misconfigurations; it reveals what access was created through the complex web of identity relationships that exist across your environment.

Our Applying Attack Path Management to Identity Security whitepaper details how Identity APM differs from these traditional approaches and why understanding identity relationships, not just assigned permissions, is critical to preventing identity-based attacks.

Until now, organizations in highly sensitive environments have been unable to adopt this approach due to the constraints of SaaS-based delivery. For organizations in restricted environments, BloodHound Enterprise on-premises delivers this capability without compromising their security requirements. Here’s how:

Data never leaves your control: Your identity data, including the complete graph of users, permissions, and relationships, stays within your security boundary. There’s no data transmission to analyze, no third-party processing to audit, and no shared responsibility model to navigate.

Reduced third-party exposure: In high-security environments, every external dependency is a potential risk. By processing identity data entirely within your infrastructure, you eliminate a significant category of third-party risk while still gaining access to sophisticated analysis capabilities.

Air-gapped and restricted network support: BloodHound Enterprise on-premises functions fully without internet connectivity. Whether you’re operating in an air-gapped network, a classified environment, or any scenario where external connectivity is prohibited or severely limited, the platform delivers complete functionality.

Regulatory and audit compliance: When your compliance framework requires demonstrable control over sensitive data processing, on-premises deployment provides clear, auditable boundaries. You can show exactly where identity analysis occurs without complex data flow documentation spanning multiple vendors.

What This Means for Your Security Operations

BloodHound Enterprise on-premises enables you to protect your most critical assets by segregating and enforcing least privilege access across your identity infrastructure without any critical identity data crossing security boundaries. Using Privilege Zones, you can accurately segment your most business-critical, on-premises assets and understand exactly where attack paths provide adversaries with access points. This visibility allows you to eliminate these paths proactively rather than discovering them during incident response.

Beyond protection, you can establish Identity APM as a continuous operational program for identifying and eliminating identity vulnerabilities in your highly regulated environment. This transforms identity security from periodic assessments or post-incident reviews into an ongoing practice that continuously discovers new risks as your environment evolves.

Our Identity APM Maturity Model whitepaper provides a framework for organizations to assess their current capabilities and chart a path toward integrating Identity APM into the fabric of their security practices, regardless of deployment model.

Through Identity APM as a practice, BloodHound Enterprise on-premises also strengthens your existing security investments. You can enrich your SIEM, SOAR, and ITDR solutions with identity attack path data to gain vital context about privilege chains and effective access without the need for persistent cloud connections. When your security operations team investigates an alert or responds to an incident, they have immediate visibility into what attack paths exist and which identities could be leveraged for lateral movement or privilege escalation.

Finally, on-premises deployment gives you the opportunity to eliminate accumulated technical debt. You can resolve legacy misconfigurations and excessive privilege that may have existed for years in restricted environments where comprehensive identity visibility was previously unavailable. As you remediate these issues, you can add guardrails to future processes to prevent the same patterns from recurring, building a more secure identity posture over time.

The Path Forward for Restricted Environments

Whether you’re protecting classified systems, managing critical infrastructure, or operating under strict regulatory frameworks, you can now adopt Identity APM as a continuous security practice without compromising your requirements. The same proven engine that has helped thousands of organizations eliminate identity attack paths is now available to run entirely within your security boundary.
