What is Remote Access Software?

The devices IT is responsible for are rarely in the same building as the people responsible for them.  Gallup’s latest data shows that 78% of US employees in remote-capable jobs now work away from the office for at least part of the week: 52% on a hybrid schedule and 26% fully remote. Add servers running in cloud regions and branch sites with no technician on hand, and walking over to a machine stops being a realistic option for most of the work that needs doing.

The problem is that work hasn’t shrunk. Patches still need verifying, services still fall over, and someone still has to work out why a server has stopped responding, usually while the people who depend on it keep working. For IT managers, reaching those systems remotely is a given. The real question is whether the way your team does it is reliable, affordable, and defensible when it counts.

Remote access software lets IT administrators connect to, control, and manage a computer, server, or other device they aren’t physically near. It makes every connection authenticated, authorized, and auditable, so teams can handle maintenance, diagnostics, and incident response from anywhere and still show who did what.

Remote access software lets IT administrators connect to, control, and manage a computer, server, or other device they aren’t physically near. It makes every connection authenticated, authorized, and auditable, so teams can handle maintenance, diagnostics, and incident response from anywhere and still show who did what.

Why native and ad hoc remote access stops scaling

Most IT teams don’t choose their remote access setup so much as accumulate it. RDP gets enabled on servers, macOS Screen Sharing gets switched on for a few Macs, and SSH profiles pile up in whichever client each admin prefers.

Every one of those connections can be secured properly on its own, but the trouble starts when there are enough of them spread across enough people that nobody can see or control the whole picture, and that point arrives sooner as the endpoint-to-technician ratio widens.

Every connection is its own island

Native tools are built to connect one machine to another, not to govern how a team reaches hundreds of them. When each connection is configured independently, the answers to these basic questions live in different places:

• Who can connect?
• Where can they connect from?
• Which accounts can they connect with?
• What restrictions are in place?

Some of those answers sit in local group memberships, some in firewall rules, and some only in an admin’s saved profiles.

That fragmentation matters most when credentials leak. A joint advisory from the FBI, CISA, and the Australian Cyber Security Centre on the BianLian ransomware group describes operators logging in with compromised RDP credentials, adding accounts to the local Remote Desktop Users group, and rewriting Windows firewall rules to let more RDP traffic in.

None of that exploited a flaw in RDP itself. It used legitimate administrative mechanisms with stolen credentials, in environments where nothing tied those changes together into something a team would notice.

A reachable server isn’t always an accessible one

Fragmented access also breaks in less dramatic ways. A change made for good security reasons elsewhere in the environment can quietly cut admins off from systems that are otherwise perfectly healthy.

Failures like this aren’t unusual. Microsoft’s documentation on Remote Desktop sign-in with Windows Hello for Business shows that it depends on a public key infrastructure and on certificates deployed to each user’s Windows Hello container. Roll out the authentication change without that groundwork, and every independently configured connection inherits the problem at once.

Free tools still cost something

Built-in tools look like the economical option because there’s no license to buy, but their real cost shows up as the labor required to keep these things running. This includes:

• Maintaining connection configurations
• Managing permissions
• Rotating credentials
• Onboarding and offboarding admins
• Troubleshooting connections that fail for reasons unrelated to the target system

Since that effort is spread across the team instead of appearing as a line item, it rarely gets counted.

Each of these problems is manageable in isolation. Together, they describe access that technically works but that the team can’t fully see, can’t rely on when policies change, and can’t put an honest price on.

What remote access software actually is

Remote access software is the layer that turns ad hoc connectivity into something a team can manage. Connecting is the easy part, so what really matters is controlling who connects, what they’re allowed to do, and what record remains afterward.

At its simplest, remote access software lets an administrator reach a system they aren’t physically in front of. It’s a controlled mechanism for establishing authenticated, authorized, and auditable connectivity to remote systems for administration, maintenance, diagnostics, or intervention during an incident.

Here’s what each part really means:

• Authenticated means the person connecting has proven who they are, ideally with more than a password
• Authorized means that identity is actually permitted to perform the task, not just to open a session
• Auditable means there’s a record of the access that holds up when someone asks about it later

That’s why the same protocols (RDP for Windows servers and SSH for Linux) can sit inside very different setups.

Remote access vs remote support

The two terms often get used interchangeably, and a common shorthand treats remote access as the connection and remote support as the help delivered through it. That’s broadly right but too simple for day-to-day IT operations. Instead:

• Remote access software is a technical capability
• Remote support software is a service activity that may use that capability, or may not need it at all

A lot of remote administration never touches a support ticket. Scheduled maintenance, certificate renewals, patch verification, and infrastructure health checks all require access without any user asking for help. In the other direction, plenty of support problems get resolved through background commands or automated remediation, with no interactive session involved.

More specifically:

The distinction matters most when assigning responsibility. Infrastructure teams typically need standing access for maintenance and operational monitoring, while support staff usually need access tied to a specific request. Those roles carry different authorization and accountability requirements, and connection records and ticket records answer different questions. Neither gives you the full picture on its own.

Common types of remote access

Remote access comes in a few distinct forms, and most environments use more than one. They differ in what they give the administrator and in what they leave unmanaged.

Sessions also differ in whether anyone is at the other end. In an attended session, the user watches the technician work, which helps when the goal is to show them how to use a piece of software. The technician can also hide the screen from the user to work faster without interference. Unattended access lets a technician reach a device with no one present and without asking for approval each time, which is what makes after-hours maintenance and patching possible.

The desktop is rarely the best way in

When people picture remote access, they usually picture screen takeover with a technician moving the mouse while the user watches. That’s technically true, but it’s not all there is. Many server and application problems can be investigated and fixed in the background without interrupting the people who depend on those systems.

Consider a Windows Server that hits 100% CPU while every available interactive RDP session is already in use. Instead of disconnecting another administrator or waiting for a desktop to free up, a technician can investigate entirely from the command line. They identify the resource-heavy processes, check the Windows services, and review how the applications are behaving. If a handful of importing and reporting services turn out to be driving the load, stopping them and setting their startup type to Manual brings CPU usage back to normal. Most of the investigation and the initial fix can be finished before interactive access ever becomes available.

Native tooling already supports this way of working. PowerShell’s Invoke-Command, for example, runs commands and scripts on one or many remote computers and returns the output, with no desktop session required.

Atera’s RMM platform builds that option into the same console technicians use for interactive sessions. Alongside screen-sharing tools like Splashtop and AnyDesk, technicians can run scripts remotely on selected devices or device groups immediately. That means you can check service states, review resource usage, or apply a fix without taking over anyone’s screen.

Where remote access software falls short

A dedicated platform improves consistency and visibility, but it doesn’t make remote access secure by itself. The BianLian intrusions above didn’t depend on a flaw in the remote access tool. They depended on stolen credentials and weak controls around legitimate administrative paths. Switching tools without addressing those conditions just moves the risk.

A few limits apply, whichever product you choose, including:

• Compromised identities stay dangerous: A platform can’t tell a legitimate administrator from an attacker holding that administrator’s valid credentials.
• Excessive privileges carry over: If every technician can reach every device, centralizing access also centralizes the impact of a single compromised account.
• The platform only sees its own activity: Changes made through separate RDP clients, SSH sessions, or other tools happen outside its view.
• Identity requirements still apply: A remote access platform has to work within your authentication policies, not around them.

Remote access software is the right foundation for reaching systems you can’t touch. How well it serves you depends on the controls, permissions, and accountability you build around it.

What to look for in remote access software

Whichever product you evaluate, check it against the same capabilities. Most of them map directly to the gaps described above.

• Strong authentication: MFA or 2FA on every session, and support for your identity provider.
• Role-based permissions: Access set by technician, device, and group, so read-only monitoring doesn’t carry the same rights as running scripts.
• Attended and unattended access: The ability to connect with a user present or reach a device with no one at it.
• Remote command and script execution: PowerShell or shell commands run on one device or a group, without opening a desktop session.
• File transfer: Copying files to and from the remote device, with each transfer logged.
• Session logging and an audit trail: Records of connections, commands, file transfers, and permission changes that admins can’t edit.
• Cross-platform support: Coverage for Windows, macOS, and Linux endpoints and servers.
• Collaboration tools: Multi-monitor support, several technicians working on one endpoint, and a chat channel to the end user during attended sessions.
• RMM, ticketing, and PSA integration: Sessions, time, and tickets linked, so technicians don’t switch between tools.
• Mobile access: The ability to respond to an incident without being at a desk.

How to secure, cost, and audit remote access

Part of the process of picking a remote access tool is deciding which controls matter most, understanding what the setup costs to run, and making sure you can prove what happened when someone asks. Those three areas determine whether remote access stays an operational asset or quietly becomes a liability.

Here’s how to make the best choice:

Lock down access without locking out your team

The features that make remote access useful to IT teams are the same ones attackers want, and because these tools are legitimate, their activity often doesn’t trip security alerts. The answer isn’t to give up remote administration. It’s to control who can use it, what they can reach, and what they can do once connected.

These are the controls to prioritize first:

• Strong authentication and least privilege: Require MFA, ideally phishing-resistant, for privileged remote access. Give admins separate administrative identities and time-limited elevation where possible. Read-only monitoring shouldn’t need the same permissions as changing services, deploying patches, or running scripts.
• Restricted network exposure: Keep RDP, SSH, and IT management interfaces off the public internet. Route access through approved VPNs or administrative gateways, and segment the network so one compromised admin workstation can’t reach everything.
• An inventory of remote access tools: Know which tools are installed, where they run, and whether they’re authorized. Use application allowlisting to block unapproved tools, including portable executables that never go through a normal installation.
• Centralized, protected logging: Record authentication attempts, sessions, privilege changes, and script execution. Store those logs somewhere admin accounts and remote management tools can’t edit or delete them. Keep direct access to log servers out of reach of RMM tools.
• Controls on remote scripting: Limit script execution to authorized staff, and add extra checks for high-impact actions. If an account tries to push commands to too many devices within an hour, trigger MFA again to confirm the source is legitimate.
• Regular patching of the access stack: Remote access clients, gateways, management agents, and the systems underneath them all need patching. Prioritize anything internet-facing and any vulnerability known to be actively exploited.

Security controls can also go too far in ways that hurt operations without adding much protection:

• Banning PowerShell or equivalent tools outright cripples diagnostics, patch verification, and service recovery. A better approach keeps scripting available to authorized admins, with execution controls and logging around it.
• Requiring individual approval for every read-only service query or log check slows incident response and breaks automated infrastructure monitoring. Routine, low-risk actions can run under preapproved permissions, with stronger controls reserved for changes that affect production services, security settings, or multiple endpoints.
• Forcing a new authentication challenge for every command has the same drawback. Time-limited sessions with risk-based reauthentication, triggered by privilege elevation, session expiry, or unusual activity, protect better with less friction.

Work out what remote access really costs

License fees are the smallest and most visible part of remote access spending. GAO’s Cost Estimating and Assessment Guide frames a reliable estimate as a full life cycle accounting of the labor, materials, and effort needed to develop, operate, and maintain a system. A free client doesn’t make remote administration free.

A realistic total cost of ownership covers five categories:

• Software and infrastructure: Subscriptions, per-technician or per-endpoint licensing, remote desktop gateways, VPN infrastructure, certificate management, and any OS licensing that remote desktop deployments require.
• Implementation and migration: Initial configuration, identity integration, MFA, firewall rules, agent deployment, and testing, plus the effort of moving existing connections when a tool stops being suitable.
• Ongoing administration: Maintaining connection settings, managing permissions, rotating credentials, onboarding and offboarding admins, and troubleshooting failed connections.
• Security and compliance: Endpoint protection, centralized logging, vulnerability management, access reviews, incident investigation, and evidence retention.
• Operational disruption: Time lost when admins can’t connect, maintenance gets delayed, or users have to hand over their desktops for troubleshooting.

Those categories roll up into a simple annual formula:

Annual TCO = Software and infrastructure + Implementation and migration (allocated to the year) + Administrative labor + Security and compliance + Operational disruption

Calculate administrative labor from recorded hours multiplied by the fully burdened hourly cost of the people involved. Measure disruption separately, using incident duration, the number of people affected, and the business impact of delayed access. Allocate carefully so the same engineering hours aren’t counted twice.

To see how quickly labor dominates, here’s an example: An organization with 200 endpoints spends an average of 15 minutes per endpoint each month on access configuration, connectivity troubleshooting, and authentication problems. That’s 50 hours a month, or 600 hours a year. At an assumed fully burdened rate of $60 an hour, administration alone costs $36,000 annually, before licensing, infrastructure, security, or downtime. Cutting that time to five minutes per endpoint would recover around 400 hours, roughly $24,000 at the same rate.

Build an audit trail that answers the hard questions

When an auditor asks who connected to a device last quarter and what they did, they’re asking for two different kinds of evidence: proof of access and proof of activity. A connection log can show that a session happened, but not usually everything that was done during it.

To build an evidence package that holds up, work through these steps:

1. Identify the device by its hostname, asset ID, or another unique reference
2. Set the audit period with exact start and end dates, normalized to a single reporting time zone so timestamps from different systems line up
3. Pull the remote connection records for that device and period, and check each connection against your list of authorized administrators
4. Match each connection to an approved change request, maintenance window, or incident ticket, and flag any that have no business justification
5. Pull records of administrative actions taken through your platform, including remote commands, scripts, and configuration changes
6. Review any recorded file transfers, and add endpoint file logs or file hashes if the auditor needs to know what was transferred, not just that a transfer happened
7. Add session recordings where your tools support them, as long as recording was enabled for the period in question and the files were retained
8. Confirm each administrator’s assigned permissions, and pull identity provider records if you need to prove a specific MFA challenge took place
9. Document any gaps in the evidence, and protect the exported package with its collection date and time zone noted

That last step matters more than it seems. In environments where admins work through individual RDP clients, SSH sessions, and locally saved connection profiles, evidence for a single server can be spread across Windows Security logs, Linux authentication logs, admin workstations, and a separate change management system. A Windows logon event only shows that someone authenticated, but not why they connected, what files moved, or whether the work matched an approved change. When retention periods differ between those systems, parts of the trail may already be gone by the time the auditor asks.

Atera gives IT teams a single starting point when an auditor asks about activity performed through the platform. Technicians can search the audit log by device, technician, or site, then narrow the results by log type, technician, and date range. The Remote Actions category covers remote connection sessions through integrations like Splashtop and AnyDesk, along with file transfers and remote command execution. Configuration changes and changes to technician roles and permissions are logged as well, and audit log entries can’t be edited, so the record works as a genuine audit trail.

Remote access for managed service providers

Managed service providers (MSPs) depend on remote access more than most internal IT teams. Clients are often in other cities or countries, site visits rarely appear in contracts, and technicians still need to install software, set up new devices, test applications, and standardize configurations over the internet.

Three requirements matter more for an MSP than for a single IT department:

• Separation between clients: Technicians should reach only the clients and devices they’re assigned, and the audit log should let you trace activity by client or site.
• Integration with RMM and PSA: Remote access works best as a module inside the RMM platform, with sessions feeding the PSA so technician time is tracked against tickets and projects. Collecting that data automatically also reduces data entry errors and supports accurate billing.
• Fewer instructions passed through the user: When a technician can inspect and fix a device directly, both the MSP and the client save time. That matters most when language barriers make phone instructions slow.

Atera combines RMM and PSA in one platform, with remote access through Splashtop and AnyDesk built in.

Remote access is only as good as the control around it

Remote access software earns its place when it does three things at once: it gets the right technician onto the right system quickly, it keeps everyone else out, and it leaves a record that holds up when someone asks what happened. Native tools can connect you. On their own, they can’t tell you who still holds working credentials, which sessions were authorized, or how many hours your team is quietly spending just keeping connections alive.

Atera’s remote access brings those pieces into one console. Technicians launch attended or unattended sessions through integrated tools like Splashtop and AnyDesk, protected by built-in 2FA. When a full desktop takeover would only get in the way, they can run PowerShell commands and scripts in the background instead. If your current setup can’t quickly answer who connected to a given server last quarter, that’s the place to start.
