Maximize Uptime and Minimize Disruption with Secure Remote Access from Cyolo

In industrial environments, operational uptime and worker safety are always the top priorities. Traditional secure remote access (SRA) methods such as VPNs and jump servers often cause delays, disrupt vital processes, and introduce new security risks. For organizations running industrial control systems (ICS), cyber-physical systems (CPS), or other operational technology (OT), these trade-offs are typically unacceptable.

Cyolo helps industrial enterprises maximize operational uptime while providing seamless, secure, and non-disruptive remote privileged access to critical assets.  

Cyolo PRO (Privileged Remote Operations) is an access solution that enables safe, seamless, and non-disruptive access to critical assets without requiring network changes or slowing operations. Built on a unique decentralized architecture, Cyolo PRO eliminates single points of failure and supports cloud, on-premises, and air-gapped deployments. This ensures continuous, remote privileged access to operational systems — even during internet outages or in fully offline environments.

By augmenting or replacing legacy SRA tools with Cyolo PRO, industrial enterprises gain zero-trust remote access that protects their OT systems and helps keep operations running smoothly.

5 Key Ways Cyolo PRO Maximizes Uptime for Industrial Enterprises

1. Cyolo PRO’s network-independent architecture enables rapid deployment with no infrastructure changes required.

Thanks to its decentralized, infrastructure-agnostic design, Cyolo PRO can be deployed without invasive and disruptive network changes. The solution works with non-routable networks, overlapping IPs, and air-gapped sites and has a lightweight footprint (deployable on NUC devices or as containers on switches, routers, and firewalls) that allows for exceptionally fast rollout across the complete OT landscape. This solves more problems with a consistent and coherent approach, meaning fewer disparate solutions and less chance of misconfigurations or gaps – both prime opportunities for downtime. 

Real-world example: A global manufacturer rolled out Cyolo PRO across 100 sites in 65 days, quickly demonstrating value and winning over stakeholders.

2. Cyolo PRO’s zero-trust architecture eliminates attack surfaces.

Cyolo PRO adheres fully to the zero-trust security model by keeping all data, secrets, and encryption keys inside the customer’s trusted boundary and never in the cloud. Even the Cyolo Global Gateway cloud offering is only a routing mesh, with no connections terminated outside the boundary and no data processed or stored in the cloud. This architecture ensures not just the highest level of security but also ultra-low latency, high availability, and no single point of failure – all crucial for OT systems where even brief delays can bring operations to a halt. 

To further improve security and reduce the attack surface for bad actors, Cyolo PRO needs only a single outbound TCP443 connection to move away from inbound firewall port openings. Plus, vaulted credentials (which also remain inside the OT boundary) and fine-grained zero-trust access policies limit the opportunity for lateral movement and the possibility of operational interruptions and downtime. 

3. Cyolo PRO’s agentlesss, browser-based approach prioritizes user experience.

Unlike legacy SRA tools that require agent downloads, Cyolo PRO delivers agentless, browser-based access to critical OT assets like TIA Portal and FactoryTalk. This simplifies adoption and removes friction for employees and especially for third-party vendors, contractors, and OEMs.

And with single sign-on (SSO) and credentials vaulting, users of all types gain secure access in as few as two clicks. This accelerates maintenance, updates, and emergency onboarding without disrupting operations. Positive user experience also improves adoption rates and prevents workarounds that may add security or safety risks and lead to downtime.

Real-world example: After adopting Cyolo PRO, a multinational food and beverage manufacturer reported, “It’s the first time we’ve had third parties ask if they could use it for more. Usually, it’s grumbling. But now the reaction is: ‘Oh, this is quite good. Can we use it for X as well?”

4. Cyolo PRO includes supervisory controls and built-in file scanning for safe remote operations.

Beyond securing the initial point of access with zero-trust protections and multi-factor authentication (MFA), Cyolo PRO extends crucial connectivity and oversight capabilities for the duration of each connection. Key features include:

• Supervised access, session recording, and full auditing for visibility and compliance.

• The ability to terminate sessions in real-time if unusual or anamlous behavior is detected.  

• Activity restrictions (for instance, blocking file uploads or risky SSH commands).

• Built-in file scanning to prevent malware or corrupted updates from crossing the OT boundary.

Cyolo PRO’s access, connectivity, and oversight controls reduce downtime risk and enable safer, more compliant remote operations.

5. Cyolo PRO supports legacy OT systems without forced upgrades.

Manufacturing, energy & utilities, and other industrial sectors rely heavily on legacy OT infrastructure that does not natively support modern security protocols. In contrast to the many SRA tools that simply ignore these systems, Cyolo PRO retrofits legacy systems to accommodate zero-trust access, multi-factor authentication (MFA), and web application firewalling (WAF) – all without requiring infrastructure changes or upgrades. This both closes critical vulnerabilities and extends asset lifecycles, allowing enterprises to maintain uptime while securing older infrastructure.

Conclusion 

With its focus on maximizing uptime and minimizing disruption, Cyolo PRO elevates access control from a basic security function to a strategic operational advantage. Industrial organizations benefit from a modern remote access solution that strengthens security, supports compliance, and keeps mission-critical systems online – without introducing the friction or fragility common to most legacy access methods.
