We've seen a seismic shift in where and how work gets done. Remote and hybrid arrangements have become the norm, offering benefits like increased flexibility, productivity, and access to talent. But this transition has also opened up new avenues for cyber threats, catching many organizations off guard.

Many companies today have at least some staff working outside of traditional office confines. According to Forbes’ Remote Work Statistics And Trends In 2024 as of 2023, 12.7% of full-time employees work remotely, plus 28.2% work in a hybrid model. Additionally, around 16% of companies already function entirely remotely, without the need for physical office space. These organizations are at the forefront of the remote work trend, proving its practicality and leading the way for future adoption.

While employees enjoy the freedom to work from anywhere, security teams are grappling with an attack surface that has exploded in size and complexity practically overnight. Outdated perimeter defenses are no match for an environment where personal devices, home networks, and cloud apps intermingle with corporate assets.

Remote work security threats 

Remote work opens the door to a range of cyber threats that can compromise sensitive data and systems. Some of the most pressing threats include:

• Physical access threats: Unattended devices in public spaces or home offices can be vulnerable to unauthorized access.
• Phishing, vishing, smishing: Social engineering attacks that manipulate users into revealing sensitive information or installing malware have surged. Phishing uses email, vishing exploits phone calls and voicemail, while smishing relies on SMS text messages. Remote workers may be more vulnerable because much of their work already takes place over the phone and text messaging.
• Social engineering: Techniques like pretexting, baiting, and quid pro quo that are used to trick users into breaking security protocols. Remote workers may be more susceptible without the security umbrella of the enterprise network present in an office environment.
• Ransomware: Malicious software that encrypts a victim's files and demands payment to restore access. The use of personal devices and networks for work increases the risk of ransomware infections.
• Malware, spyware, viruses: Malicious software designed to infiltrate and damage systems or steal data. Remote work blurs the lines between personal and corporate devices, making it easier for malware to spread.
• Wireless hijacking: Attackers exploit vulnerabilities in Wi-Fi networks to intercept data transmissions, especially on public or poorly secured home networks.
• Eavesdropping: The act of secretly listening to private conversations, potentially revealing confidential information. Poorly configured remote meeting software can enable eavesdropping.
• Traffic manipulation: Modifying unencrypted data in transit to commit fraud or steal information. The use of unsecured public networks places remote traffic at greater risk.

The consequences of these threats can be severe, including data breaches, financial and data losses, reputational damage, operational disruption, and regulatory penalties. Mitigating these risks requires a multi-layered approach to security.

Remote work security best practices

So, what can you do? Securing a remote workforce demands a combination of technical controls, user education, and robust policies. Key best practices include:

Employee training and awareness

Human error remains a leading cause of security breaches. Educating employees about potential threats and best practices is crucial. Key topics you should cover include:

• Recognizing and avoiding phishing, smishing, and vishing attempts 
• Identifying signs of social engineering like unusual requests or pressure tactics
• Awareness of ransomware and malware infection vectors
• Password hygiene and the importance of strong, unique passwords
• Safe use of generative AI tools, to prevent inadvertent sharing of sensitive data

Codify your company’s expectations in clear, accessible security policies. Provide guidance on securing home networks, keeping software updated, using secure passwords, and separating work and personal devices where possible.

Provide security tools  

Equip employees with the tools they need to work securely. Core solutions include:

• Password managers to create and store strong, unique passwords. Explore the growing role of enterprise browsers as password management solutions.
• Multi-factor authentication to prevent unauthorized access, even if passwords are compromised. Implement MFA broadly, not just for a subset of apps.
• Zero trust access models that continually verify trust, rather than assuming it based on network location or prior access. Educate staff on why zero trust is important in a perimeter-less world.
• Endpoint protection to detect and block threats on user devices. Consider solutions that work seamlessly off-network and don't hamper performance.

Protect devices

With the rise of bring-your-own-device (BYOD) models, organizations have less direct control over endpoints. Mitigate risks with device management and security policies:

• Monitor device health and compliance with security tools to maintain visibility 
• Enforce disk encryption, VPN usage, software update policies, and other baseline security settings 
• Consider strategies for keeping  work data and apps separate from personal usage

Protect information and applications 

Adopting a granular, zero trust approach to data protection and access control is critical in a remote work environment. Here are some key best practices:

• Implement role-based, least-privilege access policies to ensure users only have access to the resources they need to do their jobs. This limits exposure in the event of a compromise.
• Require multi-factor authentication (MFA), especially for administrators and sensitive resources. MFA adds an extra layer of protection, even if a password is compromised.
• Deploy data loss prevention (DLP) solutions to restrict the exfiltration of sensitive information. DLP tools can monitor and block unauthorized attempts to copy, send, or upload confidential data.
• Shift from on-device storage to the cloud to reduce data sprawl. Cloud storage provides a central, secure repository for company data, making it easier to manage access and prevent data loss from lost or stolen devices.

Implement and enforce remote work policies

Organizations must establish comprehensive policies for their distributed workforce. Key frameworks include BYOD policies, mobile device management protocols, and data governance standards. These policies create clear boundaries between personal and professional technology use:

• Establish BYOD policies with clear device approval and management requirements
• Implement mobile device management protocols for all remote endpoints
• Create data governance standards that separate work and personal usage
• Define acceptable use policies for home networks and personal devices

Well-defined policies provide the foundation for secure remote work operations.

Enforce zero trust access natively

Use built-in zero trust frameworks to verify user identity and device posture continuously. Trust is never assumed, even after initial login. Access can be dynamically adjusted based on real-time risk signals. Consider some of these practices:

• Enable credential injection for sensitive applications
• Require multi-factor authentication for access to high-value resources
• Ensure strong, unique passwords for every application
• Eliminate risk of credentials being copied, shared, or phished

Proper credential management eliminates the weakest link in most security breaches.

Shadow IT and SaaS visibility

Detect and manage shadow IT by monitoring all SaaS logins and web activity. Gain visibility into unauthorized app usage. IT can block, approve, or monitor unsanctioned applications as needed:

• Set up alerts for new or high-risk SaaS app usage
• Regularly review reports to identify trends and usage patterns
• Make informed decisions about blocking, approving, or monitoring apps
• Identify opportunities for sanctioned alternatives to risky applications

Comprehensive visibility transforms shadow IT from a security risk into manageable business tools.

Secure collaboration and file handling

Automatically scan uploaded and downloaded files for threats. Enforce sharing policies to prevent accidental exposure of sensitive documents. Control file actions at the browser level to ensure consistent policy enforcement. Consider these best practices for file security:

• Customize file handling policies for different departments and roles
• Integrate with existing cloud storage and collaboration platforms
• Block public sharing or require approval for external sharing
• Scan all file transfers for malware and policy violations

Automated file security maintains productivity while preventing data loss and malware infections.

Continuous device posture assessment

Automatically assess device health before allowing access to corporate resources. Check OS version, endpoint protection, and encryption status continuously. If devices fall out of compliance, instantly block access and alert IT. In the meantime, implement these practices:

• Configure real-time device posture checks at every login and during sessions
• Require automatic assessment of OS version and security software status
• Block non-compliant devices immediately and notify IT teams
• Ensure only secure, up-to-date devices connect to sensitive resources

Continuous monitoring ensures only healthy devices access corporate resources at any given moment.

The role of enterprise browsers in remote work security

A core element of a modern security stack for remote work is an enterprise browser. Unlike traditional browsers, enterprise browsers are purpose-built for organizations' security and manageability needs.

Enterprise browsers extend granular security policies and data protections to the browser, a critical gap in most security stacks. They enable device security posture checks, site access control, data loss prevention, and detailed logging. By building security into the browser, enterprise browsers deliver capabilities that point solutions like VPNs or cloud access brokers struggle to address.

Some key remote work security use cases for enterprise browsers:

• Enforcing least-privilege access and data security policies for SaaS and internal web apps 
• Enabling secure access to enterprise resources for unmanaged devices, without the need for full-device VPN
• Protecting sensitive corporate data from compromise on personal devices by isolating the browser 
• Gaining visibility into compliance issues and identifying anomalous user behavior through detailed audit logs

Streamline your security stack with an enterprise browser

Equipping employees with the right tools is essential for secure remote work. However, the traditional approach of stitching together point solutions can lead to complexity, user friction, and gaps in protection. 

Enter Island, the Enterprise Browser — a new class of tool that consolidates critical security functions into a single, user-friendly platform. By building key capabilities like password management, multi-factor authentication, and zero trust access directly into the browser, enterprise browsers like Island offer a more integrated and streamlined approach to remote work security.
