OT networks, a core part of manufacturing, transportation, and many other industries, need highly secure remote access (SRA) solutions. Sure, this is only one piece to the security puzzle, but finding the best secure remote access for OT networks is crucial.
The scope of OT environments differs from IT in several ways, such as the needs behind highly reliable connections, low latency, and strict uptime guarantees. This article focuses on four of the most reliable choices that OT networks can rely on for secure remote access at all times.
Key Takeaways:
- OT networks require highly secure remote access to maintain uptime, safety, and operational reliability
- Leading vendors include SonicWall, Sophos, Cisco Meraki, and WatchGuard, each with distinct strengths
- SonicWall focuses on policy-driven access control and scalable licensing for distributed environments
- Sophos and Meraki carry strengths in centralized management, with cloud visibility and ecosystem integration
- Strong SRA solutions improve security, reduce downtime risk, and support efficient remote operations in OT environments
4 Best Secure Remote Access for OT Networks Solutions
To get a good start on this topic, it helps to lean into some of the most reliable manufacturers in the industry. In this case, you’re getting a closer look at four leading secure remote control solutions from SonicWall, Sophos, Cisco Meraki, and WatchGuard.
While these aren’t the only options on the market, their reputation and history in network security solutions offer the reliability your business network needs. Focusing on factors like security, scalability, and OT suitability helps to narrow down your options here.
1. SonicWall SRA
Carrying a focus on secure, policy-driven remote access, SonicWall SRA makes it easy for distributed users. It’s more than suited to support OT environments, especially where uptime, reliability, and strict access control are a must.
This is one of the best-rated secure remote access for OT solutions, as you get licensing models that support scalability, stackable users, and even virtual appliance options. Other notable capabilities include angles like single sign-on and device visibility to help improve control, security, and operational efficiency.
2. Sophos SRA
What’s great about Sophos SRA options is that they’re integrated into the broader scope of the Sophos Central security ecosystem. Going this route means you get a combination of endpoint protection, identity security, as well as threat prevention.
Moreover, there are built-in features to take advantage of, including web filtering, authentication tools, and password protection. Sophos Central gives you the centralized management you need for deploying and enforcing remote access policies.
3. Cisco Meraki SRA
Another option, seen as some of the best secure remote access software for OT networks, is Cisco Meraki. This is a cloud-managed SRA solution, making it a great choice for those prioritizing centralized control.
In addition to that, you can utilize integrated firewalling and encrypted VPN connectivity, and the cellular failover shouldn’t be overlooked either. The overall cloud visibility of this gives IT teams what they need to monitor devices, enforce policies, and manage access in real time.
4. WatchGuard SRA
With WatchGuard’s remote access solutions for business, you’re getting a strong focus on fast, encrypted VPN connectivity. More specifically, the WatchGuard Panda VPN is created with small-scale deployments in mind.
However, you aren’t limited to this alone, as you still get the range of enterprise-grade remote access. This can be seen in benefits like seamless roaming, built-in 2FA, and flexible licensing options for various organizational needs.
Why Secure Remote Access is Critical for OT Network Security and Reliability
At the end of the day, OT networks need more than simple secure connectivity for employees. It’s about maintaining secure distributed operations and field management from more than one angle.
Here are a few core reasons as to why SRA for OT networks is so vital:
- Helps maintain teams, vendors, and engineers who need to troubleshoot remotely
- Poorly secured remote access is a massive entry point for cyberattacks
- OT environments require higher reliability than typical IT systems due to uptime and safety demands
- Short disruptions in OT networks can lead to significant production downtime, financial loss, and even safety risks
- SRA solutions enforce strict authentication and identity verification before granting system access
- Network segmentation merged with remote access controls helps to limit lateral movement
If you’re working with OT networks, then SRA is a non-negotiable. In the same vein, it’s still important to know what you’re looking for based on your unique operational demands. Having the right remote access architecture in place does well to improve operational efficiency, as well as maintain compliance with industry regulations.
The Final Word
Always remember that searching for the best secure remote access for OT networks isn’t just about the needs of a remote workforce. It’s an essential for the overall safety, reliability, and continuous operations across all critical infrastructure.
