Enterprise & Mainframe Security Hardening

Hardening the "Fortress." Get expert-led, zero-impact protection across RACF, ACF2, TSS, and the full z/OS stack to align your mainframe with modern Zero-Trust architectures.

Expert-Led Risk Reduction

Identify deep vulnerabilities in sensitive datasets, system parameters, and command authority that automated compliance scanners completely overlook.

Zero-Impact Auditing

Assessments are performed exclusively via standard, native IBM utilities with zero overhead, zero downtime, and zero data extraction risks to production.

Proactive Cyber Resiliency

Address critical mainframe skills gaps while integrating legacy subsystems with your modern Identity & Access Management (IAM) and enterprise SIEM/SOC infrastructure.

What are mainframe security services?

Mainframe security services are elite, specialized technical defense programs designed to shield your mission-critical z/OS ecosystem from escalating digital threats through comprehensive auditing, active remediation, and continuous engineering consultancy.

Rather than introducing heavy third-party software overhead, we independently analyze your overall security controls, access rules, and configurations. We review RACF, ACF2, and TSS environments remotely or onsite to ensure consistent key control compliance.

Our mainframe security assessment & hardening framework

We convert deep-system technical audit data into a prioritized hardening and Zero-Trust roadmap to ensure risk reduction never compromises infrastructure availability.

Deep-System Audit

A total evaluation of sensitive datasets, APF-authorized libraries, public resources, and administrative control procedures across all technical standards and password management layers.

Vulnerability Remediation

Delivering tailored technical remediation plans to eliminate access command exposures, strengthen ESM policies, clean up obsolete profiles, and close structural security gaps.

Modernization & Integration

Implementing advanced tooling support—including zSecure and Vanguard exploitation—to stream real-time security events directly to your enterprise SIEM/SOC for cross-platform threat hunting.

Solving your mainframe security challenges

Modern digital threats are rising quickly, leaving many enterprise mainframes exposed due to a dangerous focus on narrow detection rather than proactive hardening.

Here is how CPT Global eliminates the structural blind spots.

What does a mainframe security assessment actually review?

Our assessment provides a complete review of your overall security implementation. We inspect sensitive datasets, APF libraries, application data layers, public resource access definitions, administrative command authorities, password management configurations, and overall formal/informal security policies.

How do you perform the assessment without adding new tools or risk?

Our technical assessment is performed entirely with standard native utilities. No third-party agents, external monitoring software, or extra tool infrastructures are introduced to your environment, eliminating any potential performance or licensing overhead.

Do you support RACF only, or other external security managers?

We provide comprehensive, native expertise across all major External Security Managers (ESMs)—including IBM RACF, Broadcom CA ACF2, and CA Top Secret (TSS). We can also architect, guide, and validate full security migrations from one ESM platform to another.

What happens after the assessment is complete?

CPT Global delivers a prioritized findings report, technical vulnerability sizing, immediate "quick-win" mitigation steps, and a long-term compliance roadmap designed to reduce your management overhead while protecting systems from evolving threats.
