You need a staff member to open QuickBooks from home, a solicitor to reach case-management software from a client's office, or an accountant to retrieve a document while travelling. The request sounds simple: enable remote access, send the login details, and get on with the work.
That approach can expose far more than the intended application. A poorly configured VPN, an internet-facing RDP service, an unmanaged laptop, or a password-only account can turn a productivity project into a business continuity problem. The right way to set up remote access starts with reducing exposure, not opening ports.
Remote access is no longer a specialist tool reserved for system administrators. Cisco reported a 60% rise in authentication activity across its Duo Security technologies during the shift to remote work, with monthly authentications increasing from 600 million to 900 million. More recent research cited by Cisco found that 74% of organisations said IT users use remote access and 61% said non-IT users do as well. These figures show how remote connectivity now sits inside normal business operations. Cisco's report on the shift to remote work provides useful context for that change.
The business need is clear. Staff need dependable access to shared applications, files, desktops, and internal services without being tied to one office. The security responsibility is just as clear. Every connection creates a decision about identity, device trust, permissions, encryption, monitoring, and what happens if the user's laptop is lost or compromised.
A small business often has fewer technical resources to absorb a mistake. A law firm may need to protect confidential client material. An accounting practice may depend on applications that were designed for an office network. A growing company may have employees using a mixture of company-owned and personal devices. Each situation needs a controlled entry point rather than a collection of informal workarounds.
For a broader look at the considerations facing remote access for UK businesses, focus on how access policies, identity controls, and business requirements fit together. You can also review what remote access technology involves before choosing a platform.
Practical rule: If a remote connection reaches a sensitive system directly from the public internet, treat that design as a risk requiring justification, not as the default setup.
A secure design normally uses a managed gateway, strong authentication, restricted permissions, encrypted transport, and reliable records of connection activity. The technology can vary, but those controls shouldn't.
The three common approaches are a business VPN, self-hosted RDP, and a managed cloud desktop. They can all provide remote access, but they place responsibility in different hands and expose different parts of your environment.
A VPN creates an encrypted route between an approved device and the company network. It can work well when employees need access to several internal resources, such as file shares, line-of-business applications, and internal web systems.
The trade-off is that a VPN can extend network reach beyond the specific application a user needs. Administrators must define groups, routes, firewall rules, device requirements, and session policies. They also need to patch the VPN appliance or service, manage client software, investigate failed logins, and remove access when a staff member leaves.
A VPN is usually a sensible fit when the organisation already has capable network administration and needs controlled connectivity to an existing office environment. It isn't automatically safe because it encrypts traffic.
RDP gives a user control of a particular Windows computer or server. It can be useful for accessing software that runs on an office workstation, but the protocol should never be treated as a complete security architecture.
Directly exposing RDP creates a publicly reachable entry point. The CERT report on vulnerable remote-access services linked five security incidents to services compromised through brute force, while its incident-response findings identified weak or default passwords, missing MFA, and excessive permissions as common weaknesses.
A safer RDP design places the service behind a VPN, RDP Gateway, or brokered access layer. That adds setup and maintenance work, including certificate management, gateway hardening, account controls, patching, monitoring, and recovery planning.
A managed cloud desktop streams a controlled workspace from infrastructure operated by a provider. Instead of allowing every employee to reach the office network, the business can centralise applications, user permissions, backups, session controls, and access policies in one hosted environment.
This model reduces the amount of server and network administration the business must perform itself, although it doesn't remove the need to choose appropriate users, devices, applications, and policies. It also introduces provider dependency, so you should review support arrangements, data handling, backup processes, application compatibility, and exit provisions before signing up.
For owners comparing VDI and VPN, the practical question is simple: do you need a secure route into your existing network, or do you want the working environment itself hosted and managed away from the office? Broader discussions about exploring remote work models can help frame the operational side of that decision.
| Option | Main strength | Main responsibility | Typical concern |
|---|---|---|---|
| VPN | Secure route to internal resources | Your team manages network access and endpoints | Excessive network reach |
| Self-hosted RDP | Direct access to a particular computer | Your team hardens and monitors the full stack | Internet exposure and credential attacks |
| Managed cloud desktop | Centralised workspace and administration | You govern users and business policies | Provider selection and service dependency |
Choose the method that gives users the narrowest access needed to do their jobs. Convenience shouldn't decide the architecture.
A business VPN should be designed as a controlled access service, not installed as a shortcut around the firewall. Start by documenting what each role needs to reach. An employee who only uses a hosted accounting application shouldn't automatically receive broad access to every office device and shared folder.
A hardware VPN appliance can suit a business with an established office network, on-site servers, and someone responsible for firmware, certificates, backups, and failure recovery. A cloud-based VPN can simplify distributed workforces, but you still need to understand where authentication occurs, how devices are enrolled, and how access is segmented.
Ask vendors or consultants to explain the complete connection path. You should know which gateway receives the session, which identity provider validates the user, how the device is assessed, and what internal services become reachable after login.
Create separate groups for ordinary staff, managers, contractors, and administrators. Assign access to applications or network segments rather than granting a broad connection and hoping users only visit approved systems.
Require MFA for the VPN account and apply device requirements before allowing the session to proceed. At minimum, define expectations for supported operating systems, security updates, screen locking, malware protection, and company control over business data. Personal devices need especially careful treatment because you may not be able to verify their condition or prevent local copying.
Split tunnelling deserves an explicit decision. It can reduce the amount of traffic routed through the office, but it may also allow a remote device to connect to business systems while simultaneously communicating with untrusted networks. If you enable it, document the reason, limit the routes, and assess whether the device and applications can tolerate that risk.
A VPN isn't finished when the first user connects. Test login denial, lost devices, expired accounts, concurrent sessions, gateway failure, and access removal. Confirm that logs identify the user, device, time, gateway, and result of each connection attempt.
Users also need a simple support path. Confusing instructions encourage staff to reuse passwords, bypass controls, or install unsanctioned remote tools. Explain how to install the official client, report a lost device, recognise an MFA prompt they didn't initiate, and contact support without sharing credentials.
For businesses weighing application hosting against network tunnelling, Citrix and VPN offer different operational models. The right answer depends on whether the business needs access to an existing network or a centrally managed workspace.
RDP is useful, but standalone RDP isn't a secure remote-access solution. The most dangerous setup is a host reachable directly from the internet, especially when the owner assumes that a strong password alone will protect it.
The risk is persistent rather than theoretical. More than 85% of organisations have RDP accessible from the internet for at least part of a month, according to the industry guidance summarising 2025 Verizon DBIR data, and stolen credentials were involved in 22% of confirmed breaches. See the remote-access security guidance on RDP exposure and credential theft for the cited analysis.
Don't forward RDP directly through the perimeter. Block direct inbound access and require users to authenticate through a VPN, RDP Gateway, or managed broker before a session can reach an internal host.
Enable Network Level Authentication so the system validates identity before creating a full desktop session. Protect the gateway with strong TLS, current certificates, MFA, and administrative access controls. Where practical, restrict gateway access by device posture, identity group, geography, or approved network conditions.
If a user only needs one application, consider publishing that application rather than handing over an entire desktop. A narrower session limits what a compromised account can reach and reduces the damage caused by accidental file transfers or excessive permissions.
Use individual accounts. Shared administrator credentials make investigation difficult and allow one person's compromise to affect everyone. Apply strong password policies, account lockout or throttling controls, and separate privileged accounts from normal daily-use accounts.
Review RDP settings for clipboard, drive, printer, and device redirection. Those features can be convenient, but they can also move sensitive data between an unmanaged endpoint and a protected server. Set idle-session timeouts and disconnect inactive sessions so abandoned connections don't remain available indefinitely.
The safest RDP rule is simple: users should reach the gateway first, and the gateway should decide whether the host is reachable.
Patch Windows, the gateway, endpoint clients, and supporting security tools on a defined schedule. Monitor failed logins, unusual access times, new devices, privilege changes, and repeated connection attempts. For a practical overview of these controls, review remote desktop security before approving a self-hosted deployment.
The access method matters, but identity and operational discipline determine whether the design remains defensible. A VPN can be misconfigured. A cloud desktop can be over-permissioned. RDP can be protected by a gateway and still fail if administrators ignore compromised accounts.
NIST recommends placing remote-access servers at the network perimeter as a single point of entry, enforcing policy before traffic reaches internal networks. Its guidance also recommends MFA for both the telework device and the remote-access solution, plus VPN or TLS protection when the method doesn't already provide approved confidentiality and integrity controls. Read the NIST remote-access security guidance when documenting your design.
MFA should protect every remote account, not only administrators. Prefer phishing-resistant methods such as hardware security keys where the business can support them. If that isn't immediately practical, use an established authenticator-based method and protect the recovery process as carefully as the original login.
Conditional access can require a known device, a supported operating system, an approved location, or a healthy security posture. Don't treat a successful password as proof that the person and device are trustworthy. A stolen password can still pass the first test.
Least privilege is a daily operating rule. A bookkeeper may need one application and a limited document area. A solicitor may need a case-management workspace without access to unrelated matters. An administrator may require higher access for a task, but shouldn't use that account for email and general browsing.
Review permissions when roles change and remove access promptly when employment or supplier relationships end. Keep administrative accounts separate, limit delegated permissions, and avoid permanent access where a time-limited approval will work.
Encryption protects traffic in transit, but it doesn't make an infected laptop safe. Require supported systems, security updates, screen locking, disk encryption where appropriate, and malware protection. Decide whether personal devices can access regulated or confidential material, and define what the business can inspect, control, or wipe.
Keep remote-access clients, operating systems, gateways, and hosted applications patched. An old client can undermine a well-designed gateway, while an unpatched host can expose a user after authentication has already succeeded.
Monitoring should answer practical questions. Who connected? From which device? Through which gateway? What did the user access? Was the attempt denied, and why? Did the account behave differently from its normal pattern?
Microsoft's Remote Access tools support real-time and historical connection statistics, with historical data queried across a specified time window. Cisco's remote-access dashboards retain session information across multiple time slices, including up to a full year in tabular form. That illustrates why durable logs and routine review are part of the service, not optional reporting extras. The Microsoft connection statistics documentation describes the historical reporting capability.
Network segmentation limits the consequences of a compromised account or endpoint. Place remote-access gateways at the perimeter, separate user networks from server networks, and restrict connections between segments with explicit firewall rules.
Don't rely on training alone. Teach employees to recognise phishing, unexpected MFA prompts, fake support requests, and requests to install remote-control tools. Microsoft's incident reporting shows why legitimate collaboration and remote-access tools need tight external-access controls and an accurate inventory of which tools the organisation requires.
The controls work together. MFA reduces account takeover risk, least privilege reduces the value of a stolen account, segmentation limits movement, encryption protects traffic, and logging helps you detect and investigate misuse.
A self-hosted design can be appropriate when the business has the skills and time to operate it properly. That means maintaining gateways, patching servers, managing certificates, reviewing logs, testing backups, handling support tickets, removing access, and planning for hardware or internet failures.
For a small business owner, accountant, or law firm partner, those tasks compete with client work. The question isn't whether a VPN or RDP can be secured. They can. The question is whether your organisation can maintain every supporting control consistently after the initial setup.
A managed cloud desktop moves the working environment into a provider-operated platform. The provider can centralise application access, user administration, remote sessions, backups, monitoring, and support, while the business retains responsibility for approving users and defining who should access which systems. That division is often easier to manage than a small office server exposed through several independently maintained tools.
Monitoring remains a deciding factor. Microsoft supports historical connection reporting, and Cisco retains session data across long review windows, showing that professional remote-access operations depend on records that can be searched after an incident, not just a connection button that works today. A managed provider should explain what it records, how long it retains logs, who reviews alerts, and how it supports investigations.
Cloudvara provides hosted remote desktop access for business applications, with centralised access, two-factor authentication, backups, and support as part of its application-cloud model. Review the details of its remote desktop hosting services and ask specific questions about your applications, user roles, device policies, recovery process, and support responsibilities before migrating.
The responsible choice is the one that leaves the fewest uncontrolled pathways into business systems. If your team can't confidently operate a self-hosted VPN or brokered RDP environment, a managed service can remove much of that administrative burden while giving staff a consistent workspace from approved devices and locations.
Cloudvara can host the business applications your team needs, provide controlled remote desktop access, and support security measures such as two-factor authentication, backups, and centralised administration.
