Cyolo Releases Powerful New Capabilities to Redefine Secure Remote Access for OT
Why VPNs Are a Poor Fit for Vendor Access in OT Manufacturing Environments
From Blind Trust to Full Visibility: How to Take Control of Third-Party OT Access
2026 Gartner® Market Guide for CPS Secure Remote Access
The resilience of modern data centers depends increasingly on the grey space operational systems — power distribution, cooling, environmental controls, fire and life-safety systems, physical security, and building management platforms — that keep digital services running.
Cyolo PRO (Privileged Remote Operations) enables agentless, supervised, least-privilege access for the internal teams and third-party vendors supporting energy, cooling, safety, and facilities operations across distributed sites. Vaulted credentials, session recordings, and policy-based access controls help protect uptime without slowing maintenance or service workflows.
Why Critical Facility Access Needs Tighter Access Control
When remote access into operational infrastructure is poorly governed, organizations expose the very systems responsible for power continuity, thermal stability, life safety, environmental monitoring, and physical protection. For facilities and operations leaders, remote access is an uptime, safety, and compliance issue — not just an IT convenience.
52% of impactful data center outages cite power as the primary cause
$100,000 — cost of the most recent significant outage for 54% of operators
15% of breaches involve a third party
Case Study: How Cyolo Helps a Fast-Growing Colocation Operator Protect Critical Facility Access
A large multi-site colocation provider was expanding quickly, bringing new buildings and operational assets online while supporting hyperscale customers. The systems that kept each site running — cooling, electric physical security, and other building infrastructure — needed to be reachable by employees, specialists, and contractors across multiple locations.
But the existing model relied on a generic IT VPN, individual system clients, and manual controls that were difficult to scale. Cyolo helped replace that friction with agentless remote access, stronger separation between identity and the internet, centralized control, supervisor workflows, and the auditability needed for operational and security teams. The result is a more manageable way to support remote sites, vendors, and critical facility systems as the estate grows.
The Problem: Operational access was fragmented across VPNs, local clients, manual rules, and expanding contractor activity.
What Changed with Cyolo: Cyolo introduced agentless access, supervision, policy enforcement, and better control over who can reach which systems.
Why It Matters: Critical facility teams can now scale remote operations without losing visibility, traceability, or governance.
