One partner, end to end

Build it. Connect it. Secure it.

Most organizations juggle separate vendors for infrastructure, networking, and security — and the seams are where risk hides. CIS unifies all three under one accountable partner, with zero-trust designed in from the first rack to the last policy.

Build

We design and build modern on-premise infrastructure and datacenters — architected for performance, resilience, and secure-by-default operation.

Connect

We interconnect your sites, datacenters, and clouds into one secure, high-performance global fabric — no matter where your operations run.

Secure

Every layer is designed zero-trust and backed by fractional CIO/CISO leadership — from architecture and ransomware defense to incident response.

What we do

Everything you need to build, connect & secure

Engage us for a single initiative or as your ongoing technology and security leadership. Every engagement is scoped to your environment, budget, and risk — and built zero-trust by default.

  • Post-merger systems & security integration

Audit & Compliance

Get audit-ready and stay there, aligned to the standards you're held to.

  • Readiness & gap assessments (SOC 2, ISO 27001, PCI DSS)
  • Policies, controls & evidence preparation
  • Auditor liaison & continuous compliance

Cost Optimization — OPEX & CAPEX

The fractional advantage

Enterprise-grade security expertise, right-sized for you

A full-time CISO is a six-figure commitment before a single control is deployed. With CIS you get the same caliber of leadership on a flexible engagement — scaling up during projects and audits, and down when you're steady.

  • Start in weeks, not months — no lengthy executive search
  • Objective, vendor-neutral guidance
  • Knowledge transfer that levels up your internal team

Questions

Frequently asked questions

What is a fractional (virtual) CIO or CISO?

A fractional vCIO/vCISO is a senior technology and security leader who works with you part-time — owning strategy, infrastructure decisions, and cyber risk — for a fraction of the cost of a full-time executive.

Does CIS provide infrastructure services or only cybersecurity?

Both, under one accountable partner. CIS designs and builds on-premise infrastructure and datacenters, interconnects your sites and clouds worldwide, and secures everything zero-trust — from architecture to incident response.

What does “zero-trust by design” mean?

It means security is architected into your infrastructure from the start — every user, device, and connection is continuously verified — rather than bolted on afterward.

What size of organization does CIS work with?

Growing and mid-sized organizations that need enterprise-grade technology and security leadership but can't justify — or don't yet need — a full-time CIO or CISO.

How does an engagement start?

With a short, no-obligation consultation. We assess your systems and risks, prioritize the highest-impact work, then deliver and improve alongside your team.

Which security frameworks does CIS align to?

NIST CSF, ISO/IEC 27001, CIS Controls, Zero Trust (NIST 800-207), IEC 62443 for OT, plus SOC 2 and PCI DSS — aligned to your actual obligations.

Can CIS help reduce our technology costs?

Yes. As your fractional CIO we review OPEX and CAPEX spend, consolidate vendors, licensing and cloud, model on-prem vs cloud economics, and prioritize investments by risk and return — often funding the engagement through the savings it finds.

Do you support mergers, acquisitions, and audits?

Yes. CIS runs pre-deal technology and cyber due diligence, leads post-merger systems and security integration, and gets you audit-ready — readiness assessments, controls and evidence, and auditor liaison for SOC 2, ISO 27001, and PCI DSS.
