Remote access software lets you connect to and use a computer, server, or network from somewhere else. It provides the means to access a system across a network; the broader term “remote access” describes that connection or access relationship.
What does remote access software do?
It creates a way for a user to reach a remote device or network and interact with it. Depending on the tool and its configuration, that may mean viewing and controlling a computer, accessing services on a network, or performing administrative tasks. The exact capabilities vary by product; the term alone does not specify which features are included.

The Cybersecurity and Infrastructure Security Agency (CISA) describes remote access software as enabling a user to connect to and access a computer, server, or network remotely. NIST defines remote access in an organizational context as access by a user or information system communicating through an external network that the organization does not control, such as the Internet. CISA’s Guide to Securing Remote Access Software and the NIST glossary describe related but distinct ideas: one is the tool; the other is the access relationship.

How is it different from remote administration and RMM?
Remote access, remote administration, and remote monitoring and management (RMM) overlap, but they do not mean exactly the same thing. CISA distinguishes them as follows:
#1 Best Overall
- Notes: This remote switch button is specifically designed for use with AV Access iDock C20 (B0CP4PD3SM)and iDock D23(B0CRDQW4GT) models.
- Instant Device Switching at Your Fingertips: Switch between Input 1 and 2 with one button press. Smooth transitions keep your workflow seamless and stress-free.
- LED Indicators for Total Control: Know your active device instantly with clear LED status lights, ensuring easy, confident control.
- Compact Design, Big Convenience: This 40mm diameter button, just 9.5mm thick, fits any setup. Its 1.2m/3.94ft cable provides flexible, space-saving convenience.
- Seamless Compatibility with iDock Series: Designed to work flawlessly with the iDock C20 and D23 models, it enhances your docking experience by providing effortless control across your devices.
| Term | Meaning |
|---|---|
| Remote access software | Enables a user to connect to and access a computer, server, or network remotely. |
| Remote administration solution | Provides network and application access along with administrative control of a device remotely. |
| Remote monitoring and management (RMM) | Uses an agent on an endpoint to continuously monitor a machine’s or system’s health and status, while also enabling administration functions. |
Commercial products can combine capabilities from more than one category, but not every remote access tool is an RMM platform. The distinction is useful when deciding what a tool can do and what level of oversight it may require. These definitions are from CISA’s 2023 joint guide.
Why do organizations use remote access software?
Organizations use remote access and RMM capabilities to maintain and improve IT, operational technology (OT), and industrial control system (ICS) services. CISA’s examples include:
Rank #2

Is remote access software the same as remote desktop software?
Not necessarily. Remote desktop software is commonly used to view or control a computer’s desktop from another location. Remote access software is a broader category: CISA’s definition also covers access to servers and networks, and tools may offer capabilities beyond desktop control. Product terminology varies, so check a tool’s documented features rather than assuming that every product labeled “remote access” works the same way.
Rank #3

Is remote access software safe?
The category is dual-use. Authorized staff can use these tools for support and maintenance, but an access tool can also give an intruder a path into a system if it is misused, exposed, or compromised. CISA warns that “cyber threat actors increasingly co-opt these tools for access to victim systems.” That is a reason to govern and monitor their use, not evidence that every remote access product or connection is inherently unsafe.
For organizations, NIST guidance gives a framework for managing remote connections rather than a universal checklist for home users. NIST SP 800-171 Rev. 3 recommends defining permitted remote-access types and their configuration and connection requirements, authorizing access before a connection is established, routing connections through authorized and managed access-control points, and authorizing privileged remote commands and access to security-relevant information. The publication is scoped to protecting controlled unclassified information in nonfederal systems and organizations; see NIST SP 800-171 Rev. 3.

CISA also advises defenders to understand normal network activity and how approved remote-access tools behave, correlate alerts with other suspicious activity to reduce false positives, and use endpoint detection and response tools to monitor for unauthorized remote-access software. Its guide, published June 6, 2023, names products as examples of tools that threat actors may leverage; those examples are dated security guidance, not a current product ranking or endorsement.
