When an employee works from the office, their device is protected by the corporate firewall, segmented network, and enterprise network security policies. When they work from home or a café, none of those protections are present. 67% of security breaches reported in Spanish SMEs in 2025 originated from remote work devices or connections.
The hybrid model is here to stay, but most SMEs have not adapted their security architecture for an environment where employees access company systems from home networks, hotels, coworking spaces, or while travelling. Traditional perimeter security no longer works when the perimeter is diffuse.
The Five Risk Vectors of Remote Work
Unsecured WiFi Networks
Home and public networks don't have corporate network security controls. An attacker on the same network can intercept unencrypted traffic.
Unmanaged Devices
Laptops without encryption, outdated antivirus, and no applied security policies. A lost or stolen laptop can expose all corporate information.
Weak Credentials Without MFA
Remote access credentials are attackers' top target. Without MFA, a password stolen in a phishing attack grants full access to all systems.
Shadow IT
Remote employees using unauthorised applications (personal Dropbox, WhatsApp for corporate documents) to compensate for a lack of adequate tools.
Essential Security Measures for Remote Work
The starting point is multi-factor authentication (MFA) on all remote access systems: VPN, corporate email, cloud applications, and admin panels. 99.9% of account compromise attacks are blocked by MFA. The second priority measure is mobile device management (MDM): a centralised system that applies security policies, encrypts the disk, enables remote wipe in case of loss, and keeps software updated on all corporate devices.
81% of data breaches related to remote work are due to compromised credentials. Multi-factor authentication eliminates 99.9% of these risks.
Zero Trust: The Security Model for the Hybrid World
The Zero Trust model starts from the premise that no user, device, or application should be trusted by default, regardless of whether they are inside or outside the corporate network. Each access to a resource must be explicitly verified (identity + device + context) and privileges must be minimal and temporary. For SMEs, Zero Trust adoption can begin with three steps: universal MFA, access segmentation by role, and anomalous behaviour monitoring.
Securing the Home Network: A Practical Checklist for Remote Employees
- Change the router's default password and keep its firmware updated
- Use WPA3 or at least WPA2 encryption on the home Wi-Fi
- Separate work devices from smart TVs, consoles and guest devices with a guest network
- Connect to company resources only through the corporate VPN or a Zero Trust access gateway
- Avoid public Wi-Fi for work, or use a mobile hotspot instead
- Keep the company's endpoint protection active and never disable automatic updates
Network security for remote employees cannot depend on each person's technical knowledge. The company should define a short remote working policy, provide managed devices where possible and use device management tools to enforce encryption, updates and screen locking. Combined with centralised logging of remote access, this gives IT visibility of who connects, from where and with which device, and allows suspicious sessions to be blocked quickly.
Protecting a distributed team requires secure access, managed devices and continuous monitoring. Our cybersecurity service helps SMEs assess their remote working risks and put the right controls in place.

How do you secure the network for remote employees?
Combine secure access, such as a corporate VPN or a Zero Trust gateway, with multi-factor authentication, managed and encrypted devices, up-to-date endpoint protection and basic home network hygiene: strong router passwords, WPA2/WPA3 and separating work devices from personal ones.
Is a VPN enough for remote employee network security?
No. A VPN encrypts traffic, but if credentials are stolen or the device is compromised, an attacker gets the same access as the employee. It should be complemented with MFA, device health checks and least-privilege access, which is the basis of the Zero Trust model.
What is Zero Trust and why does it matter for remote work?
Zero Trust means no user or device is trusted by default, even inside the network. Every access request is verified based on identity, device status and context, which limits the damage of stolen credentials and suits teams working from many locations.
Should remote employees use personal devices for work?
It is best to avoid it. If personal devices are allowed, they should be enrolled in device management with a separate work profile, encryption and the ability to wipe company data remotely if the device is lost.
What are the biggest network security risks for remote employees?
Phishing and stolen credentials, unsecured home routers, public Wi-Fi, unpatched devices and the use of unapproved cloud apps to share files. Most incidents can be prevented with MFA, regular updates and clear, simple policies.
