In the era of data-driven decision-making, IT leaders face an ever-growing challenge: ensuring that critical workloads remain available, secure, and resilient in the face of increasing cyber threats and system failures. At the foundation of any highly available and cyber-resilient IT architecture lies Tier 0 infrastructure—the core systems responsible for authentication, identity management, and overall access control.

Tier 0 systems, including Active Directory, privileged access management (PAM) solutions, and key infrastructure components, serve as the gatekeepers to an organization’s digital assets. Compromising Tier 0 means jeopardizing an entire IT environment. As cyberattacks become more sophisticated, businesses must adopt a proactive approach to securing and managing Tier 0 to mitigate risk and ensure operational continuity.

Jeskell’s Approach to Tier 0 Security & Resilience

Jeskell Systems, an IBM Platinum Business Partner with 35 years of experience, specializes in fortifying Tier 0 infrastructure with a multi-layered security approach that balances performance, accessibility, and cyber resilience. Our expertise extends across Federal agencies and commercial enterprises, where stringent compliance and security demands require best-in-class solutions to protect mission-critical workloads.

By leveraging IBM Security and IBM Storage Defender, Jeskell ensures that Tier 0 components are not just protected but recoverable in the event of an attack. Our approach includes:

  • Cyber Resilient Storage – IBM FlashSystem with Safeguarded Copy provides immutable snapshots that protect Tier 0 data from ransomware and insider threats.
  • Privileged Access Controls – IBM Security Verify and IBM Security Identity Governance help secure access at the highest levels, ensuring only authorized personnel can manage Tier 0 resources.
  • Zero Trust Implementation – Adopting a Zero Trust security model that enforces strict access verification and lateral movement restrictions to prevent attackers from escalating privileges.
  • Automated Threat Detection – IBM QRadar and IBM Guardium enable continuous monitoring and analytics to detect anomalies and unauthorized access attempts before they escalate.

The Cost of an Unprotected Tier 0

A breach at Tier 0 is not just a security incident—it’s a business disaster. Organizations that fail to secure Tier 0 risk complete loss of control over identity management, making recovery extremely difficult and costly. According to IBM’s Cost of a Data Breach Report 2024, the average cost of a breach has risen to $4.88 million, with compromised credentials being a leading cause.

Jeskell’s security-first, compliance-driven approach ensures that your Tier 0 environment is always available, protected, and rapidly recoverable in the face of evolving cyber threats.
