Hararei works across security, network, and cloud infrastructure.
These areas are now closely linked in enterprise environments. Decisions related to access, connectivity, identity, and data protection influence each other and shape outcomes in risk, performance, and operational overhead. Our focus is not limited to technology selection. Greater emphasis is placed on how systems are applied in practice, how they integrate with existing environments, and how design choices perform over time under real operating conditions.
Hararei was established by technology leaders who have managed enterprise infrastructure in complex, large-scale environments. This includes direct responsibility for systems, operations, and transformation initiatives across global organizations.
As a result, the focus is not limited to technology selection. Greater emphasis is placed on how decisions translate into operational outcomes, including system dependencies, performance constraints, risk exposure, and long-term maintainability.
Experience includes significant work within financial services and other environments where reliability, security, and regulatory considerations are central to system design and operation.
Hararei’s approach is shaped by experience on the buy side of enterprise technology, including direct responsibility for vendor selection, system implementation, and ongoing operation within complex environments.
This perspective provides a clear understanding of how technology decisions affect integration, performance, cost, and operational overhead over time. It also reduces reliance on vendor-driven assumptions, focusing instead on how solutions behave in practice.
The result is a more grounded approach to architecture and implementation, based on real-world constraints rather than idealized models.

Hararei works with enterprises on security, network, and cloud decisions that have a direct impact on risk, performance, and operational overhead. The focus is not only on selecting technologies, but on how those technologies are applied in real environments where constraints, tradeoffs, and integration challenges are present.
Hararei covers a range of infrastructure and security areas, including secure access, data protection, SD-WAN, endpoint control, and cloud environments. These areas are often interconnected, and decisions in one domain influence outcomes in others.
The emphasis is on practical application. This includes how technologies operate under real conditions, how they integrate with existing systems, and how they affect performance, manageability, and risk exposure over time.
Hararei works in different roles depending on requirements. This may include acting as a direct advisor to leadership teams, supporting internal technical groups, or participating in project delivery across different phases.
Engagement can range from early-stage evaluation through to implementation and operational support, with flexibility to act as lead, co-lead, or supporting resource.
Hararei works with a selected set of platforms across security, networking, and cloud domains, including technologies such as Zscaler, Aruba, MSP360, Twingate, and others. These relationships allow Hararei to support both advisory and implementation activities across different solution areas.
Platform selection is based on suitability for the environment rather than alignment to a single vendor. This allows for flexibility in architecture design and avoids unnecessary constraints where requirements vary.
Hararei combines advisory input with implementation support. This includes architecture definition, technology selection, deployment oversight, and ongoing refinement where required.
The approach is not tied to a single platform. Recommendations are based on the requirements of the environment, with consideration given to operational constraints, cost, and long-term maintainability.
Hararei‘s senior management collectively have over 60 years IT experience working primarily for global financial firms. They have spearheaded large-scale cloud, transformational change, IaaS & PaaS, grid computing, and security strategies for regional and global organizations.
