Building Tomorrow

One Sustainable IT Solution at a Time

Origins

Evolution

Expansion

Commitment

Cistor was founded by The Sustainable IT Guy, Anthony Levy. Recognising a burgeoning need within the market, Anthony observed a challenge. Major equipment manufacturers, such as Cisco, sought partners to embrace their remanufactured technology. Thus, a gap existed - a reliable channel for accessibility.
From the humble confines of a London-based office, Cistor embarked on solving this dilemma. What began as a solution-seeking venture has blossomed into enduring partnerships, typified by our sustained relationship with a global telecommunications giant.
As a trusted ally to Cisco, we've transitioned from supplying modest quantities of refresh stock to managing and supplying their global inventory.
Expanding our reach, we extend the same dedicated service to a spectrum of clients worldwide. By forecasting their needs, leveraging market insights, and ensuring readiness, we're committed to delivering precisely what they require, precisely when they need it.

Why Customers Choose Cistor

Technical Depth That Goes Beyond Surface Level

We bring enterprise-grade network architecture expertise across complex, multi-vendor environments designing infrastructure properly, not just deploying equipment.

We Maximise the Value of What You Own

Before recommending upgrades, we identify optimisation opportunities, extend platform lifecycle, and protect your existing investment from unnecessary replacement.

Speed Without Compromising Stability

Rapid response and global delivery matter but never at the expense of design integrity, performance, or long-term resilience.

Commercially Intelligent Infrastructure

Every recommendation must improve performance, reduce risk, or strengthen ROI. Sustainability and technology only matter when they deliver measurable business value.

How Cistor can help you

Network Design and Architecture Consulting

Network design shapes long-term cost, resilience, and scalability, and poor decisions can create costly technical debt. Cistor supports organisations at critical architectural stages, delivering commercially sound, multi-vendor network designs that enable growth, optimise performance, and extend lifecycle value for both service providers and mid-sized enterprises.
