Remote Working IT Setup: What Employees Need to Work From Home Securely
Setting up a secure remote working environment requires more than just opening a laptop at home. Whether you are an employee working from your spare room or an employer supporting a distributed team, the IT infrastructure behind remote work needs careful attention. Without proper configuration, home networks and personal devices can become entry points for threats that would otherwise be blocked on a secure office network.
This guide covers the practical steps involved in building a remote working setup that is functional, maintainable, and secure. It is written for employees who want to understand what good practice looks like, and for business owners or IT leads who need a clear checklist for supporting remote workers in the United Kingdom.
Device Policy: Company-Issued Hardware Versus Personal Devices
One of the first decisions in any remote working setup is whether employees use company-issued devices or personal hardware. Each approach has distinct implications for security, support, and ongoing management.
Company-Issued Devices
A managed company device gives the IT team full control over the software installed, the security tools deployed, and the policies enforced. This makes it significantly easier to maintain a consistent security posture across the entire workforce. Updates, patches, and configuration changes can be pushed centrally, reducing the risk that individual employees fall behind on critical maintenance.
For businesses in the UK, using company-issued devices also simplifies compliance with data protection obligations under UK GDPR. When all work happens on managed hardware, the risk of sensitive company or customer data being stored on an unsecured personal laptop is considerably lower.
Personal Devices
Bring Your Own Device (BYOD) arrangements are common among smaller businesses and freelancers. They reduce upfront hardware costs and give employees flexibility. However, BYOD introduces a range of security challenges that are worth understanding before adopting this model.
Personal devices typically lack the endpoint management software that IT teams use to enforce security policies. They may have outdated operating systems, unpatched applications, or disabled antivirus tools. When a personal device is also used for personal browsing, shopping, and social media, the attack surface expands further.
If personal devices must be used, consider implementing a baseline security checklist. This might include requiring up-to-date operating systems, enabling full-disk encryption, installing approved security software, and using a separate work profile where the platform supports it.
Hybrid Approaches
Some businesses take a middle ground by providing company hardware for sensitive work while allowing personal devices for routine tasks. This layered approach can balance cost and security, provided the boundaries between high-risk and low-risk activities are clearly defined and understood by employees.
VPN Requirements for Remote Access
A Virtual Private Network (VPN) is one of the most commonly recommended tools for remote working. When you connect to a VPN, your internet traffic is routed through an encrypted tunnel to a server operated by your organisation or a trusted VPN provider. This prevents eavesdroppers on the same network from intercepting your data and masks your IP address from external observers.
For business use, a VPN is typically used to access internal resources such as file servers, internal applications, and development environments that are not exposed to the public internet. Without a VPN, these services would need to be accessible from the internet directly, which significantly increases the attack surface.
Choosing a Business VPN
Consumer VPN services marketed to individuals are generally not suitable for business use. They often lack the user management, access controls, and audit logging that organisations need. A business VPN solution should support directory integration (such as Azure Active Directory), allow granular access policies, and provide visibility into who is connecting and when.
Common business VPN options include solutions that integrate with cloud platforms, traditional site-to-site VPNs for organisations with on-premises infrastructure, and zero-trust network access (ZTNA) tools that verify user identity and device health before granting access to specific applications.
VPN Versus Direct Remote Desktop Access
Some organisations choose to use Remote Desktop Protocol (RDP) or similar remote access tools without a VPN, exposing the service directly to the internet. This approach can work for single-user scenarios but introduces notable risks. Exposed RDP ports are a frequent target for automated attacks, and without the protection of a VPN tunnel, all traffic including authentication credentials travels in clear text across the internet.
Where VPN or ZTNA solutions are feasible, they provide a meaningfully higher level of protection. If direct remote access is unavoidable, it should be protected with strong multi-factor authentication, a strict lockout policy, and ideally a jump host or bastion server that limits direct exposure.
Multi-Factor Authentication on All Accounts
Multi-factor authentication (MFA) is one of the most effective security controls available. It requires a second form of verification beyond a password, making it substantially harder for attackers to gain access even if a password is compromised or leaked.
For remote workers, MFA should be enabled on every account that supports it. This includes email, cloud productivity suites, VPN clients, project management tools, and any internal systems accessed from home. The effort required to set up MFA is small compared to the protection it provides.
Authentication Methods
The most common MFA methods vary in their resistance to different types of attack. Authenticator applications that generate time-based one-time codes are widely supported and work offline. Hardware security keys offer strong protection against phishing but require physical possession of the device. SMS-based codes, while common, are considered weaker because SIM swap attacks can intercept them.
Encouraging employees to use an authenticator app or hardware key rather than SMS is a practical step that improves the overall security of the remote working setup.
Backup Codes and Account Recovery
When enabling MFA, it is important to store backup codes securely. These codes provide a way back into an account if the primary authentication device is lost or unavailable. Written copies stored in a secure location, or stored within a password manager, are reasonable approaches for most users.
Home Router Security
Remote workers connect to the internet through their home router. This device is the gateway between the home network and the wider internet, and its security has a direct impact on the safety of all connected devices, including work laptops and smartphones.
Most home routers shipped by internet service providers in the UK have reasonable default settings, but they are not optimised for security. Out-of-date firmware, default administrator credentials, and exposed management interfaces are common issues that can be addressed without specialist knowledge.
Updating Router Firmware
Router manufacturers release firmware updates to patch security vulnerabilities and improve stability. Many consumer routers do not update automatically, so checking the admin interface periodically for available updates is worth making a habit. If the router is very old and no longer receives updates, replacing it with a newer model that continues to receive security patches is a sensible investment.
Router Administrator Credentials
Default router passwords are widely documented and can be found in public databases. Changing the administrator username and password to something strong and unique is one of the simplest security improvements. It is also worth checking that remote management is disabled unless there is a specific need to administer the router from outside the home network.
Wi-Fi Security Settings
Using WPA3 encryption on the home Wi-Fi network is the current best practice. Where WPA3 is not supported by the router or connected devices, WPA2-AES is the minimum acceptable standard. WEP encryption, which is still found on older hardware, offers almost no protection and should be avoided.
A strong, unique Wi-Fi password prevents neighbours and visitors from accessing the home network. Keeping the network name (SSID) non-identifying also avoids drawing unnecessary attention to the household.
Secure Communication Tools for Remote Teams
Remote work relies heavily on messaging, video calling, and collaboration tools. Choosing the right platform and configuring it securely matters, particularly when sensitive business information is being discussed.
End-to-end encrypted messaging platforms provide protection against interception, though the level of security depends on how the platform is configured and whether encryption is enabled by default. Video conferencing tools should require meeting passwords by default and avoid using guessable meeting IDs. File sharing should happen through approved business channels rather than personal cloud storage accounts.
Establishing clear guidelines about which tools are approved for work communication helps employees avoid accidental data exposure. This is particularly relevant in households where multiple people share internet connections and devices.
Backup and Data Recovery for Remote Workers
Working from home does not change the need for reliable backups, but it can make the responsibility less visible. In an office environment, IT teams typically manage backups centrally. Remote workers may need to take a more active role in ensuring their work is backed up.
The first step is to confirm that work files are being saved to network drives or cloud storage provided by the employer, rather than solely to the local hard drive of the laptop. Local-only storage creates a single point of failure. If the laptop fails, is lost, or is encrypted by ransomware, work data stored only locally may be unrecoverable.
For employers, providing automated cloud backup solutions for remote devices removes this responsibility from individual employees and ensures consistent coverage across the workforce.
Employee Security Awareness
Technical controls are only part of the picture. Remote workers are frequently targeted by phishing emails, social engineering calls, and impersonation attempts. Awareness training helps employees recognise these threats and respond appropriately.
Effective security awareness training covers how to identify suspicious emails, what to do if they suspect an account has been compromised, and the importance of reporting concerns promptly. Simulated phishing exercises, conducted carefully and without punitive consequences, can help reinforce learning in a practical way.
For businesses in the UK, security awareness training also supports compliance with cyber insurance requirements and frameworks such as Cyber Essentials, which many organisations use as a baseline security standard.
Support Arrangements for Remote Workers
When a remote worker encounters an IT issue, the path to resolution needs to be clear. Unlike an office environment where a colleague can take a look at a screen, remote support requires either remote access software or clear escalation procedures.
IT support contracts can define response times, available channels (phone, email, ticketing system), and the scope of assistance provided. For businesses without a dedicated IT team, engaging a managed service provider can ensure remote workers have access to reliable technical support without needing to maintain in-house expertise.
Before contacting support, it helps to have basic information ready: the device affected, the operating system in use, a description of the issue, and any recent changes that may have preceded the problem. This reduces back-and-forth and speeds up resolution.
Regular Security Reviews for Remote Setups
Remote working setups should not be configured once and forgotten. Periodic reviews help identify configuration drift, outdated software, and emerging risks before they become problems.
A practical review might include checking that all devices are enrolled in patch management, confirming MFA is active on all accounts, verifying VPN configurations have not been altered, and reviewing which services have access to sensitive data. These checks can be incorporated into quarterly or annual IT health checks.
For businesses, documenting the expected configuration for remote worker devices provides a baseline for these reviews. When a device deviates from the standard configuration, it can be flagged for correction.
