Cybersecurity Tips for Remote Working

Why Remote Work Changes the Security Environment

Remote working has fundamentally changed how organisations manage their digital security.

Because employees now access data from various locations, the traditional concept of a secure office network perimeter is no longer the primary line of defence.

Businesses, on the other hand, have to deal with a distributed environment where risks like unsecured home networks and unmanaged personal devices are more common.

SMEs have to think beyond the old perimeter mindset. It’s no longer just about the office firewall – it’s about safeguarding each user’s identity and every device they rely on.

A measured, well-planned approach to these risks tends to work far better in practice.

Some parts can be tightened, others simplified, and together they build a setup the business can trust. Sensitive information stays under control, yet the team keeps the freedom to work in the way that actually fits their day.

It also sharpens expectations – people understand what’s allowed, what’s best avoided, and how a small slip can create space for something far more serious.

Understanding the Current Threat Landscape

Cyber threats have shifted with the rise in home and hybrid working. Attackers look for weak links, whether that’s unsecured Wi-Fi, outdated software, or a lapse in basic security habits.

Instead of manually targeting specific companies, threat actors are more and more using automated tools to search the internet for weak remote connections.

Ransomware-as-a-Service and other models make it possible for even unskilled attackers to run complex campaigns.

Data shows that a lot of businesses in the UK have cyber attacks every year, and medium-sized businesses are especially at risk. A large proportion of these incidents begin with phishing attacks.

Artificial Intelligence (AI) is often used in modern phishing campaigns to make emails that look and sound like real emails.

Criminals are now leaning on deepfake tools for “vishing” – voice-based fraud that slips past the usual checks. It’s quick, convincing, and often hard to spot in the moment.

If you want a clearer sense of how these tactics play out, our guide on how to keep your business safe from phishing attacks walks through the main warning signs – as well as offers some practical steps teams can take to stay ahead.

Identity Management as the Primary Control

In a remote setting, verifying user identity effectively replaces the physical security of an office.

Because of this, Multi-Factor Authentication (MFA) is widely seen as a standard requirement for all remote access points.

SMS-based authentication is available, but many people think it’s less secure because of the risk of SIM-swapping. Using Time-based One-Time Password (TOTP) apps or number-matching notifications is a stronger way to stop users from accidentally letting in fake logins.

FIDO2 hardware keys make it harder for hackers to steal your information by adding an extra layer of protection for senior staff or high-value accounts.

Using enterprise password managers also makes sure that workers use different, hard-to-guess passwords for each service – lowering the chance that duplicate passwords will be used.

Azure Active Directory (Azure AD) has Conditional Access policies that can make security even better.

These rules take a moment to check two things: the user’s location and the condition of the device they’re using. If both look right – meaning the device is healthy and the connection makes sense – access to company data goes ahead.

If not, the system slows things down or blocks it outright.

Securing Remote Devices

Making sure that the physical devices that employees use are safe is a basic part of remote cybersecurity.

It’s usually better to use business-owned laptops than personal ones because this lets IT administrators enforce the same security rules for everyone.

To keep corporate data properly protected, a mix of technical controls is usually brought into play.

Full-Disk Encryption: Tools such as BitLocker lock down the entire drive, so if a laptop is lost or stolen, the data can’t be accessed.
Firewall Configuration: Firewalls on operating systems should be turned on and locked so that users can’t turn them off.
Inactivity Timeouts: Devices should lock themselves after a short inactive spell. It closes the gap where an unattended screen could be misused.
Patch Management: Standards like Cyber Essentials set a clear expectation. Important updates must be applied within 14 days, or those known vulnerabilities stay open.
Access Rights: Restricting local administrator privileges for daily work helps prevent malicious software from installing itself.

Comparing VPN and Zero Trust Network Access (ZTNA)

Businesses that want to enable remote work usually narrow things down to two options.

One is Zero Trust Network Access (ZTNA). The other is a Virtual Private Network (VPN).

A standard VPN connects the remote device to the corporate network.

This can work in some situations, but it can also let attackers move sideways, which means that if a remote device is hacked, the attacker may be able to get into the whole network. VPNs can also send traffic in a way that isn’t very efficient, which could slow down cloud apps.

ZTNA is increasingly adopted as a modern alternative for general staff access.

Application-Level Access: ZTNA limits each user to the specific applications they’re meant to use. Nothing beyond that is exposed.
Reduced Visibility: The underlying network stays out of sight. It isn’t presented to the public internet, which cuts down what an attacker can discover.
Continuous Verification: Every access decision is checked in the moment. The system looks at who the user is, plus the state of the device they’re on.
Improved Performance: ZTNA can connect traffic straight to the cloud. In many setups, that shortens the path and helps reduce latency.

A lot of small and medium-sized businesses (SMEs) use both ZTNA and VPNs. ZTNA is for most users, and VPNs are for network administrators who need more access.

Device Management: MDM vs. MAM

How you manage devices usually comes down to one thing – who owns the hardware, the business or the employee.

Mobile Device Management (MDM)

With MDM software, the company has full control over the device. This lets IT teams send out updates, enforce encryption, and do a full remote wipe if they need to. Usually, this level of control is used for assets owned by businesses.

Mobile Application Management (MAM)

People often use MAM on their own devices, especially in Bring Your Own Device (BYOD) setups.

MAM doesn’t manage the whole phone or laptop. Instead, it creates a secure, encrypted space for work apps such as Microsoft Teams and Outlook.

This stops business data from being copied to personal apps and lets the company delete only the business data without deleting the user’s personal files.

This separation helps businesses deal with GDPR risks by making sure they can still get to their data.

Securing Cloud Data and Managing Shadow IT

Files stored in services like Microsoft 365 sit in a safer spot than those left on unsecured local drives. Even so, standard retention policies don’t offer full protection. For real resilience against loss or corruption, a third-party backup service is the stronger option.

Remote work also brings its own habits. One of them is shadow IT – situations where people turn to unapproved tools to get tasks done.

IT teams can find unauthorised apps with the help of tools like Cloud Access Security Brokers (CASB).

Also, you can set up Data Loss Prevention (DLP) policies to find and stop people from sharing sensitive information with people outside your company.

Best Practices for Home Networks

Home networks are often less secure than office networks, but there are a few things you can do to make them stronger.

If your hardware supports it, you should use WPA3 encryption. WPA2-AES is the baseline you should work from.

Changing the default administrator passwords on your router helps close off easy entry points, and keeping the firmware updated adds another layer of protection against automated attacks.

Using a “Guest Network” to keep work devices separate from smart home devices like cameras and speakers can lower the risk even more. Privacy filters on screens are also helpful for stopping visual data theft in public or shared areas.

UK Compliance Considerations

Remote working introduces specific considerations for adhering to UK standards such as Cyber Essentials and GDPR.

For Cyber Essentials, the scope of assessment changes in a remote setting. While ISP-provided routers are generally out of scope, the software firewall on the device becomes the primary boundary. Compliance requires that all software is supported and licensed, and that patches are applied promptly.

Regarding UK GDPR, data controllers remain responsible for personal data regardless of where it is processed. Using personal devices to store unencrypted work data can create compliance issues.

Organisations must report any serious data breach to the Information Commissioner’s Office (ICO) within 72 hours.

Mitigating Human Risk Through Training

When security awareness is high, technical controls work best. Training has to change because AI-generated phishing emails don’t usually have the same spelling and grammar mistakes as they used to.

Employees should be told to double-check strange requests for money or data through another channel, like a phone call.

People also need to know about “quishing,” which is when phishing uses QR codes. When employees feel safe reporting mistakes, security teams can respond quickly to possible incidents.

Incident Response Procedures

What you do in the first hour of a security incident can have a big effect on how it turns out.

Power: Users shouldn’t turn off a compromised device because this can erase memory (RAM) that is important for forensic analysis.
Connectivity: Start by taking the device off the network. Unplug the cables or switch off Wi-Fi – make sure to disconnect it completely.
Isolation: IT teams can then use Endpoint Detection and Response (EDR) tools to isolate the device at a logical level.
Reporting: Any incident should be reported through a secure, offline route. Avoid using the company email, as it may already be compromised.

Companies should keep a paper copy of their incident response plan so they can get to it even if their internet goes down.

Conclusion

To keep remote workers protected, it helps to step away from perimeter-based defences. Focus instead on the data itself, the health of each device, and the identity behind every login.

Businesses can lower their exposure in a couple of ways. Updating ageing VPN setups is one of them. Keeping a closer eye on the risks tied to unmanaged devices is another.
