Remote Work Security: How to Protect Company Data Outside the Office

Remote work is how modern business works. From home offices and kitchen tables to coworking spaces and coffee shops, work is happening everywhere. And while that flexibility is great for people and productivity, it also opens the door to new cybersecurity risks if the right protections aren’t in place. 

At Atekro, we see this every day: businesses doing great work remotely, but unknowingly exposing sensitive company data because home networks and personal habits simply aren’t built for enterprise‑level security. According to a 2025 industry analysis, 92% of IT professionals say remote and hybrid work has increased cybersecurity threats, and more than 38% of cyberattacks last year specifically targeted remote infrastructure such as home routers and VPNs.  

In this blog, we’ll break down the real risks of remote work environments and walk through the essential security controls every organization should have in place to protect company data, without making work harder for your team. 

Common Remote Work Security Risks You Can’t Ignore

Remote work fundamentally changes the security perimeter. When employees work from the office, their devices sit behind layered, enterprise-grade defenses, monitored firewalls, segmented networks, and tightly controlled access. At home, much of that protection disappears. About 78% of organizations reported at least one security incident linked to remote work in 2025, and the average cost of those breaches reached over $4.5 million. 

Most home networks are designed for convenience, not security. Default router settings, infrequent firmware updates, and shared connections with personal devices like smart TVs or gaming consoles increase the likelihood that a compromised device can become a stepping stone to a work laptop. This exposure is what makes many remote work risks more severe than they would be inside a corporate office.  

Against that backdrop, the most common remote work security risks tend to fall into a few clear patterns. 

Insecure Home and Public Networks 

Many home and public Wi‑Fi networks are built for convenience, not defense. Weak router configurations, outdated firmware, or shared networks with personal devices can allow attackers to observe traffic or pivot toward work systems. 

Social Engineering and Deceptive Emails 

Phishing remains one of the most effective attack methods. Remote employees are often targeted with convincing emails or messages designed to trick them into revealing credentials or running malicious software, especially when they’re working independently without quick peer validation. 

Unmanaged or Personal Devices 

Devices that aren’t centrally managed may miss critical security updates, lack endpoint protection, or use weaker authentication. When personal and work use overlap, the risk of accidental exposure increases. 

Poor Credential Hygiene 

Stolen or guessed passwords continue to be a primary cause of breaches. Reused credentials or overly simple passwords can give attackers access far beyond a single system. 

Data Exposure in Transit and at Rest 

When information is sent or stored without proper encryption, it becomes vulnerable to interception or unauthorized access, particularly outside trusted office networks. 

Physical Access Gaps 

Remote devices are more likely to be left unattended, transported, or used in shared spaces. Without safeguards, a moment of inattention can quickly turn into a data incident. 

Essential Security Controls for Remote Work 

Effective remote security is about layered protections that work together. These controls address both technical risk and everyday human behavior. 

1. Secure Connections with Virtual Private Networks (VPNs)

VPNs create encrypted tunnels between remote devices and company systems, protecting data from interception on untrusted networks. 

They are especially important when employees work from home or travel, where network security can’t be guaranteed. VPN usage should be mandatory, easy to use, and centrally managed and not left to individual discretion. 

2. Endpoint Security: Firewalls, Antivirus, and Monitoring

Every remote device is an endpoint, and each one needs consistent protection. 

Strong endpoint security includes: 

• Host-based firewalls to control inbound and outbound traffic 

• Advanced malware protection that detects suspicious behavior, not just known threats 

• Central monitoring to identify issues early 

Regular system updates are a critical part of endpoint defense. Security patches close known vulnerabilities, and delayed updates often leave devices exposed longer than necessary. 

3. Physical Device Protection

Remote work increases the chance of devices being lost, stolen, or accessed by others. 

Organizations should require: 

• Full disk encryption 

• Automatic screen locking 

• Strong local authentication 

• The ability to remotely wipe lost or stolen devices 

Employees should be trained to store devices securely, lock screens when stepping away, and avoid working with sensitive information in public spaces. 

4. Identity Security: Password Managers, MFA, and Access Controls

Credentials are still one of the most valuable assets attackers target. 

Using a password manager helps employees create and store strong, unique passwords without friction. Multi‑factor authentication adds a second verification step that can stop attackers even if a password is compromised. 

Role‑based access control ensures users only have access to what they need, limiting the impact of both mistakes and breaches. 

5. Encryption for Data in Transit and at Rest

Encryption protects information even when other controls fail. 

Remote environments make encryption essential for: 

• Email and file sharing 

• VPN connections 

• Cloud storage and local devices 

When encryption is consistently applied, intercepted or stolen data becomes unreadable and far less valuable to attackers. 

6. Network Segmentation for Home Offices

Separating work devices from personal devices significantly reduces the risk of lateral movement across a home network. Employees should be guided to use separate Wi-Fi networks (such as a dedicated SSID) or VLANs where possible, maintain strong router credentials, and keep networking equipment up to date with the latest firmware. 

Organizations can deploy company-owned security appliances, such as managed firewall or secure gateway devices, that connect to an employee’s home network. These appliances create physical network segmentation between corporate and personal traffic, isolating business systems from other home devices. They can also be preconfigured to automatically establish encrypted VPN tunnels to the corporate network, ensuring secure, policy-controlled connectivity without relying solely on the employee’s home router. 

7. Secure Data Storage and Backup Practices

Remote employees should store work files in approved cloud collaboration tools rather than locally on their devices. This ensures data is protected, encrypted, and recoverable if a device is lost or damaged. 

Centralized storage also simplifies backup, access control, and incident response. 

8. Cyber Awareness Training

Even the best technology can’t stop every attack.  Regular cybersecurity awareness training helps employees recognize suspicious activity, avoid common traps, and report issues quickly. When people understand the why behind security controls, they’re far more likely to follow them. 

Conclusion  

Remote work doesn’t have to mean higher risk. With the right mix of technology, policy, and education, businesses can protect their data while empowering employees to work flexibly and confidently.

FAQs 

Why does remote work increase cybersecurity risk?
Remote work expands the attack surface outside enterprise-managed networks, making devices and data more exposed to threats like phishing, unsecured Wi-Fi, and unmanaged devices.  

What is the most effective way to protect data on remote devices?
A combination of VPN encryption, endpoint protection, strong identity controls (like MFA), and secure storage practices reduces risk far more than any single tool alone. 

Do employees really need cybersecurity training for remote work?
Yes, human behavior is a major factor in breaches, and training helps employees recognize phishing and unsafe practices, reducing incident rates and strengthening overall security. 

How does role-based access control help in remote security?
Limiting access to only what a user needs prevents unnecessary exposure and reduces the blast radius if an account is compromised. 

Why is network segmentation recommended for home offices?
Separating business devices from personal devices on home networks reduces the chance that a compromised personal device can infect or access corporate systems. 

How often should remote employees back up their work data?
Regular automatic backups via secure cloud tools help ensure data is recoverable if a device is lost, stolen, or compromised.
