# Best OT Secure Remote Access Software

  *By [Lauren Worth](https://research.g2.com/insights/author/lauren-worth)*

   Operational technology (OT) secure remote access software is used to secure remote connections between operators and OT environments. Typically, these environments consist of industrial equipment and machinery that present physical and digital risks if compromised.

OT is used to monitor and control physical infrastructure while information technology (IT) manages data and information systems. Companies use OT secure remote access software to manage users, allocate access privileges, and monitor behaviors for anomalies, threats, or misuse. These tools are traditionally managed by IT and security teams who specialize in complex industrial environments such as manufacturing and utilities.

Increasingly connected equipment and expanding remote workforces have increased the need for businesses to control access to their OT securely. These tools have similar features to many [privileged access management (PAM) software](https://www.g2.com/categories/privileged-access-management-pam) and [IoT security solutions](https://www.g2.com/categories/iot-security-solutions). However, OT secure remote access software is used exclusively in OT environments rather than broader IT systems or non-OT environments.

To qualify for inclusion in the OT Secure Remote Access category, a product must:

- Facilitate remote access specifically to OT environments
- Provide user provisioning and governance features
- Manage tasks such as remote maintenance while enforcing strict access controls
- Monitor and log remote access sessions

## Buyer Guide

### What You Should Know About OT Secure Remote Access

Operational technology secure remote access lets authorized users safely connect to and manage industrial control systems (ICS) and other OT devices remotely. Remote access security software gives access and control of equipment from anywhere with an internet connection without the need for physical presence.

OT secure remote access software is a specialized solution designed to provide secure access to [operational technology](https://www.g2.com/glossary/operational-technology-definition) systems that are critical to industries such as manufacturing, energy, utilities, and transportation. It makes sure that engineers, technicians, plant managers, and other authorized personnel can do their jobs from remote locations without risking exposure to cyber threats.

OT secure [remote access](https://www.g2.com/glossary/remote-access-definition) comes in handy when on-site access is impractical or impossible, such as emergencies, off-hours, or when dealing with geographical limitations.

Setting up remote access security enhances operational efficiency and supports business continuity by guaranteeing that critical systems can be accessed and managed anytime you have an internet connection.

### Features of OT Secure Remote Access Software

It’s important to shield your infrastructure from unauthorized parties to maintain integrity and confidentiality. Some common features of OT secure remote access software are as follows. 

- **Network segmentation** divides the network into separate segments, each containing a subset of the devices and assets. It enhances security by stopping compromised segments before the breach extends to other parts of the network.
- [Virtual local area networks](https://www.g2.com/articles/network-virtualization#:~:text=network%20virtualization.%20A-,virtual%20LAN,-is%20a%20subnetwork) **(VLANs)** create logically separate networks within the same physical one. Like segmentation, VLAN support in remote access software enables safe, controlled access to specific network segments, which helps enforce security policies and reduce the attack surface. This segregation simplifies network administration for OT devices.
- [Network mapping](https://www.g2.com/glossary/network-mapping-definition) shows you your network by graphically displaying network devices, paths, and connections. Network mapping is important for identifying all devices in the OT environment and how they interact, which is essential for troubleshooting.
- [Asset management](https://learn.g2.com/asset-management), in the context of OT secure remote access, is the ability to track and manage information regarding network devices and systems. Solid asset management recognizes vulnerabilities, manages updates, and sustains your security posture. This centralized repository simplifies tasks like tracking asset health, configuration, and scheduling maintenance.
- [User provisioning](https://www.g2.com/articles/user-provisioning) and governance functionalities empower administrators to create user accounts within the software. This keeps unauthorized personnel out of the system, minimizing the risk of shady login attempts.
- **Role-based access control (RBAC)** assigns system access to users based on their role within the organization. Users are granted access only to the devices and functions necessary for their assigned tasks.
- **Policy-based access controls** , as the name indicates, use policies to determine whether access requests should be granted. Policies can include factors like time of day, location, or device type. These functionalities establish predefined rules that govern user access.
- **Endpoint security** protects endpoints, such as user devices and workstations, from [malware](https://www.g2.com/glossary/malware-definition). It includes antivirus software, firewalls, and intrusion detection systems. Endpoint security also makes remote devices comply with security policies.

### Types of OT Secure Remote Access Software

Each type of secure remote control software differs in terms of ease of use, flexibility, and comprehensiveness of security features. Here are some of the different types.

- **Virtual private networks (VPNs):** [VPNs](https://www.g2.com/categories/business-vpn) extend a private network across a public network. This means users can send and receive data across shared or public networks as if their devices were directly connected to the private network. VPNs encrypt all data in transit and offer a safe conduit for remote access.
- [Endpoint security](https://learn.g2.com/endpoint-protection) **:** This term refers to the practices used to protect endpoints on a network. It often includes antivirus, firewall policies, [intrusion prevention systems](https://www.g2.com/categories/intrusion-detection-and-prevention-systems-idps). It may also involve making sure that the endpoints meet certain security standards before they can access the network.
- **Point-to-point protocol over Ethernet (PPPoE):** This network protocol encapsulates PPP frames inside Ethernet frames. Mostly used for broadband modem connections, it provides authentication, encryption, and compression.
- **Internet protocol security (IPsec):** is a protocol suite for securing [internet protocol](https://www.g2.com/glossary/internet-protocol-definition)(IP) communications by authenticating and encrypting each IP packet of a communication session. It’s often used alongside VPNs to secure the tunnel created for remote access.
- [Network access control (NAC)](https://www.g2.com/articles/network-access-control) **:** NAC systems enforce security policy compliance on devices before they’re allowed to access the network. They grant differential access to network resources based on a user’s role, device type, device health, or time-of-day restrictions.
- **Zero trust approach:** The [zero trust model](https://learn.g2.com/zero-trust-model) assumes that no system, network, or service operating outside or inside the perimeter should be trusted. Instead, it advocates for rigorous identity verification and strict access controls applied both externally and internally.
- **Secure shell remote access (SSH):** This is a cryptographic network protocol for operating network services securely over an unsecured network. It’s widely used for logging in to remote machines to execute commands, but also supports tunneling, forwarding Transmission Control Protocol (TCP) ports, and X11 connections.
- [Single sign-on (SSO)](https://www.g2.com/articles/what-is-single-sign-on) **:** SSO lets users log in once to gain access to multiple systems. This simplifies the user experience, but it must be managed correctly to maintain an appropriate level of security.
- **Desktop sharing:** [Remote desktop software](https://www.g2.com/categories/remote-desktop) lets users remotely view and operate a computer as if they were seated in front of it. This is used for remote technical support, collaboration, and presentation.

### OT vs IT security 

OT security and Information Technology (IT) are two distinct domains with unique security challenges.  **IT** focuses on managing and processing information, primarily through digital systems and networks. 

**OT** , on the other hand, is concerned with controlling physical devices and processes, such as those found in manufacturing plants, power grids, and oil refineries. While they may overlap in some areas, their fundamental differences require tailored security approaches.

**IT** encompasses a wide range of technologies, including computers, servers, databases, and software applications. IT security aims to protect sensitive data and systems from cyber threats such as hacking, malware, and data breaches.   

**OT** systems often use specialized hardware and remote access security to monitor and control industrial processes, ensuring safety, efficiency, and reliability. OT security focuses on protecting these physical systems and OT devices from cyberattacks that could disrupt operations, cause physical damage, or lead to safety hazards.

**Convergence of IT and OT**

The increasing integration of IT and OT systems, driven by the [Internet of Things (IoT)](https://www.g2.com/glossary/iot-security-definition) and Industry 4.0, has blurred the lines between the two. This convergence creates new security challenges as traditional IT security measures may not be sufficient to protect OT systems.
