8 Proven Ways to Improve Data Security in Remote and Hybrid Work

The workplace has been transformed. What was a pandemic-era adjustment has become the new normal: employees work across time zones, on personal devices, and in environments you don’t own or control. The office perimeter? Gone.

In this new world, data doesn’t stay put; it flows across home networks, unsanctioned apps, and public cloud platforms. Each of these touchpoints introduces risk and together they require a completely different security mindset. Working outside the office exposes remote workers to more cyber threats than office-based work.

A significant challenge is the widespread use of personal devices for work purposes. Nearly 40% of employees access corporate data on personal devices, while 70% use work devices for personal tasks. Adding to the risk, approximately 30% of remote employees admit to sharing their work devices with friends or family, thereby increasing the likelihood of data breaches.

This isn’t just about deploying more tools. But re-architecting trust itself from location-based security to identity-first, from endpoint control to behavior monitoring, and from one-time policies to continuous enforcement.

If you’re still thinking perimeter-era in a parameterless world, your defences are already behind. This article examines how leading organisations are addressing this challenge with innovative strategies tailored to the current work environment.

A Complex, Expanding Threat Landscape

Hybrid work may have boosted productivity and employee satisfaction, but it has also redrawn the security battlefield. What used to be a centralized IT environment is now a fragmented, constantly shifting ecosystem of endpoints, networks, and user behaviors all beyond the reach of traditional defenses.

In this new normal, every remote employee effectively becomes their own branch office, complete with a unique mix of devices, tools, and risks. According to a 2024 ResearchGate study, remote workers generate more unmanaged endpoints than their in-office counterparts. That’s not just an operational headache; it’s a gateway for ransomware, credential theft, and data leakage.

“With more employees working remotely, the attack surface in organizations has become larger. They have more endpoint devices, networking connections, and software to secure, all of which greatly increase the workload for security staff who are often stretched thin, which also adds to the complexity of what teams must secure." Kumar Avijit, Vice President  Research firm Everest Group.

On top of that, compliance demands haven’t eased, they've intensified.  It's because the traditional perimeter of corporate IT has changed. With employees working from home, using personal devices, and leveraging cloud services, sensitive data now flows through diverse and often unsecured environments. This increased complexity raises the risk of data breaches and regulatory violations, prompting authorities to enforce stricter rules and tighter oversight to protect privacy and secure data wherever it resides.

From HIPAA and GDPR to sector-specific mandates, organizations must now enforce consistent policies across environments they don’t fully control. When sensitive data moves through personal devices, public clouds, and consumer-grade apps, proving compliance becomes a daily uphill battle.

6 Key Data Security Risks in Remote and Hybrid Work

Remote work isn’t just an operational shift, it’s a redistribution of risk. When work moves beyond the office, so do the vulnerabilities. What was once managed within firewalls and controlled environments is now scattered across home routers, personal devices, and third-party cloud services. The result? A security model that’s stretched thin and increasingly reactive.

Here are the five core challenges organizations must grapple with:

1. The Expanded Attack Surface

Home networks were never built for enterprise-grade security. You can’t patch an employee’s router or secure every IoT device on their network but attackers can exploit them. From shared laptops to smart speakers, each device creates a potential entry point into your corporate ecosystem. Additionally, the use of mobile phones with work emails and unsecured cloud sync tools significantly expands the threat landscape. 

These devices commonly bypass corporate security stacks, making detection and segmentation harder. For example, suppose a compromised IoT device shares a network with a work laptop connected to a corporate VPN. In that case, attackers can pivot using lateral movement techniques, such as ARP spoofing or DNS hijacking.

2. Data Sprawl and Shadow IT

When sanctioned tools are clunky or slow, employees often turn to quick fixes—such as personal Google Drives, Dropbox links, or WhatsApp for file sharing. These tools might boost productivity in the moment, but they operate outside IT’s visibility. Without DLP policies or audit trails, sensitive data becomes untrackable and unrecoverable in a breach.

The result is a fragmented data ecosystem with no single source of truth. Sensitive files get stored in unmanaged personal clouds, forwarded across consumer-grade messaging apps, or cached in browser extensions with unclear security practices. 

3. Diminished Visibility

Legacy monitoring tools assume users and devices are inside the perimeter. But in a hybrid environment, that assumption breaks down. IT teams often lose sight of endpoint activity, struggle to trace lateral movement, and frequently discover breaches only after damage has been done. Without unified endpoint telemetry or modern logging pipelines, detection becomes a matter of guesswork.

As a result, IT and security teams face “visibility gaps”—blind spots where they can no longer observe endpoint behavior, detect command-and-control activity, or trace lateral movement across networks. Without unified endpoint telemetry, lateral attacks using fileless malware, PowerShell abuse, or credential stuffing go undetected until post-incident forensics reveal the breach.

4. Inconsistent Security Hygiene at the Edge

Patch cycles, antivirus updates, and password policies are easier to enforce in a controlled environment. However, in remote settings, many of these controls are left to individual users. Some skip updates. Others use weak passwords or share devices with family members. Weak passwords are a leading cause of more than 80% of organizational data breaches. These gaps, often unintentional, make your weakest endpoint the attacker’s strongest advantage.

5. Delayed Incident Response and Recovery

When a breach occurs in a remote context, every step in the response chain slows down. Isolating devices, retrieving logs, or even communicating with the affected user takes longer. In some cases, the IT team may not even be alerted in time. The longer the delay, the greater the blast radius and the harder the recovery.

6. Vulnerabilities in Chat Platforms

Chat apps have become the new battleground. Instead of crashing meetings, attackers quietly slip into chat channels, blending in and observing conversations over weeks or months. They build fake trust, gather inside info, and patiently wait for the perfect moment to strike. For remote workers who rely heavily on chat to connect, it’s easy to miss subtle signs of someone posing as a colleague or vendor. This makes chat a surprisingly vulnerable entry point that needs careful monitoring and user awareness, not just technical controls.

How to Protect Your Hybrid Workforce from Data Security Risks

It’s time to move past the marketing jargon. “Zero Trust” and “secure collaboration” sound impressive, but unless they’re grounded in practical, integrated action, they’re just words. Securing a hybrid workforce requires deliberate choices, aligned systems, and a deep understanding of how people actually work in 2025.

Here’s what that looks like in practice:

1. Adopt a Living Zero Trust Framework

Zero Trust isn’t a product—it’s a mindset. It starts with the assumption that no user or device should be trusted by default, even if they appear to be inside the network. Trust must be earned, validated, and continuously reassessed.

To begin, document a clear Zero Trust strategy, similar to a Project Initiation Document, that defines what you're protecting, why it matters, and how you'll measure its impact.

Each business scenario (e.g., securing SaaS, protecting identities) requires its own asset inventory. Identify and classify critical assets like data, applications, and infrastructure, based on business value and compliance requirements. Define who governs them, how they’re managed, and what recovery looks like if compromised.

Progress should be tracked in two ways: how effectively you're mitigating key risks, and how mature your Zero Trust controls are across identity, devices, network, applications, and data. Standards such as ISO/IEC 27001 and ISO 31000 provide structured methods for benchmarking your program and measuring alignment with enterprise risk objectives.

2. Use Tools Designed for Modern, Distributed Work

Security gaps often happen because many teams still rely on old-school systems that weren’t designed for remote or hybrid work. Cloud platforms like Microsoft 365 and Google Workspace aren’t just for email and file sharing; they come packed with powerful security features tailored for modern workflows.

It’s also key to regularly review sharing settings. Watch out for:

• Open external sharing links
  
• Anonymous access permissions
  
• Overly broad API access that can create loopholes

To maintain comprehensive visibility and control, it’s essential to integrate your cloud security tools with SIEM (Security Information and Event Management) or CASB (Cloud Access Security Broker) platforms. This integration provides a unified dashboard that consolidates user activity data across all applications, making it easier to spot anomalies. 

You’ll receive real-time alerts whenever unusual behavior or policy violations occur, enabling your security team to investigate and respond quickly. Ultimately, this connected approach accelerates threat detection and containment, minimizing potential damage in today’s fast-paced hybrid environments.

3. Think Behaviorally, Not Just Technically

Security events often begin with subtle behavioral anomalies, not blunt-force breaches. Modern security tools must analyze context, time of access, device type, geolocation, and typical user patterns to spot red flags early.

For example, if an employee suddenly downloads large volumes of sensitive data at 2 a.m. from an unfamiliar device, that’s a red flag even if their credentials are valid. Context-aware access policies can trigger step-up authentication, such as multi-factor authentication (MFA) challenges or temporary access blocks, to verify if this activity is legitimate.

Building on this, User Behavior Analytics (UBA) should be a core part of detection, not just alerts from antivirus or firewalls. UBA helps identify insider threats, compromised accounts, or even risky mistakes before they escalate. It turns noisy logs into meaningful signals by learning “normal” behavior and flagging deviations in real time.

4. Use Split-Tunnel VPNs and SD-WAN

Not all traffic should be treated equally. If your organization is still using a flat, single-tunnel VPN setup from years ago, you're not just behind, you’re vulnerable. Attackers are aware of how to exploit overextended tunnels, unsegmented traffic, and weak authentication. It's time to evolve.

With split-tunnel VPNs, you can direct only high-risk or sensitive data through encrypted channels, while routine traffic bypasses the VPN, reducing load and improving performance. SD-WAN takes it a step further by dynamically routing traffic based on application, user identity, and real-time risk scoring.

5. Leverage Cloud Access Security Brokers (CASB)

CASBs bridge the visibility gap in cloud environments especially in remote teams. They help monitor and enforce policies across SaaS platforms, flag shadow IT usage, and block unauthorized data transfers. In a hybrid setup, this is crucial for managing risk in tools like Dropbox, Slack, or Zoom tools that are often used outside of official governance.

With a CASB, you can be assured that no matter where or how your team works, your data remains visible, governed, and protected, without compromising productivity or trust.

6. Use Strong Identity and Access Management (IAM)

Traditional password-based access is no longer sufficient. Organizations need federated identity systems (like Azure AD, Okta, or Ping) integrated with multi-factor authentication and least privilege access models. Combine this with behavior-based access policies, such as risk-adaptive authentication, to dynamically adjust security based on context.

Critical to this architecture is enforcing multi-factor authentication (MFA) universally and adopting a least privilege access model to minimize attack surfaces. Beyond static policies, behavior-driven, risk-adaptive authentication dynamically adjusts access requirements based on contextual signals—such as device posture, geolocation, time of access, and anomalous behavior—ensuring that higher-risk requests trigger additional verification or outright denial.

This adaptive approach transforms IAM from a static gatekeeper into an intelligent, continuous risk assessor, essential for Zero Trust frameworks and resilient security postures in hybrid and cloud environments.

7. Remote Patching and Device Management

Rolling out MDM or endpoint tools is just the starting point remote patch management requires much more than automation. In distributed work environments, the real challenge lies in ensuring patches are successfully installed, verified, and don’t introduce new problems. 

Connectivity issues, failed installations, and poor cross-team coordination can quietly undermine your security posture. That’s why patching strategies must combine smart automation with human oversight, clear roles, and real-time accountability. 

Governance is key: patches should be tracked, validated, and rolled back safely if needed. And when it comes to access, the goal isn’t to lock everything down, but to enable just-in-time, role-based permissions that reduce risk without disrupting workflows.

Securing access isn’t about locking everything down—it’s about granting the right access at the right time with the right level of trust. That requires a smart mix of automation, context, and oversight, without slowing down your teams or compromising user experience.

8. Implement Multi-Factor Authentication (MFA) Everywhere

For remote and hybrid workers, MFA might sound like just another step in logging in, but it’s one of the strongest protections you can put in place. Passwords alone aren’t enough; they can be stolen, guessed, or reused. MFA adds a second layer of security, such as a code from your phone or a fingerprint, making it much harder for attackers to gain access, even if they have your password.

It’s important to protect every way people access your systems, whether they’re working from home, using a VPN, or logging into cloud apps. MFA blocks many common attack routes, like phishing and stolen credentials.

In a world where your workforce is spread across locations and devices, MFA is not optional; it's essential for keeping your data and systems secure.

Practical Work-from-Home Security Tips That Work

Securing a remote workforce isn’t just about rolling out more tools; it’s about giving employees clear, actionable guidance that fits into their real-world work environment. These are the practical steps that reduce risk day to day:

1. Encrypted Backups

Remote teams especially those handling regulated or client-sensitive data, must use end-to-end encrypted backup systems. Local files should never be the only copy. Automate off-site backups and regularly test restore workflows.

2. Device Isolation for Risky Tasks

Use virtual machines (VMs) or sandboxed environments to separate high-risk activities (like accessing unknown websites, opening suspicious attachments, or testing scripts) from the rest of the system. It’s a simple layer that can prevent small mistakes from becoming major breaches.

3. Personal Firewalls and Centrally Monitored Antivirus

It’s not enough to tell users to install antivirus software. Deploy enterprise-grade firewall and AV tools with centralized monitoring, allowing IT to verify that protection is active and up to date, regardless of location.

Above all, focus on clarity over complexity. Most employees want to do the right thing—they just need clear, practical security instructions that are tailored to their actual work processes.

Case Studies: Real-World Lessons in Data Protection and Access Governance

Sometimes, the best way to understand the real risks is to examine what has happened to others. These stories illustrate how even large companies can suffer significant damage when data protection and access controls fail, and what we can learn from their mistakes.

Conclusion: Designing for Security in a Distributed World

The remote and hybrid work model isn’t a temporary disruption; it’s the new foundation of how modern organizations operate. But with this flexibility comes complexity, especially when it comes to safeguarding data. Traditional perimeter-based defenses are no longer sufficient. Today, security must be adaptive, identity-driven, and behavior-aware.

Protecting a hybrid workforce requires more than deploying tools it demands rethinking trust, intelligently decentralizing control, and embedding security into everyday decisions and workflows. That means:

• Building policies that reflect how people work.
  
• Leveraging Zero Trust and context-aware systems.
  
• Equipping employees with clarity, not just controls.
  
• Fostering a culture where security is shared, not siloed.
  

There’s no silver bullet but there is a blueprint. Organizations that embrace this shift with a strategic, layered, and human-centric approach will be better equipped to secure their data, people, and future.

Frequently Asked Questions (FAQs)

1. What are the biggest cybersecurity risks in a hybrid work model?

The top risks include expanded attack surfaces (such as home networks and personal devices), increased use of shadow IT, reduced visibility for IT teams, and inconsistent patching or device hygiene. Each of these creates exploitable vulnerabilities if left unaddressed.

2. Is using a VPN enough to secure remote access?

No. While VPNs encrypt traffic, they aren’t sufficient alone. Organizations should implement split-tunnel VPNs, SD-WAN, CASBs, and Zero Trust policies to ensure access is context-aware and risk-based, not just encrypted.

3. What’s the role of Zero Trust in remote work security?

Zero Trust is essential. It ensures that access is never granted by default and is always verified based on user identity, device health, location, and behavior. It’s especially important when users and devices operate outside traditional network boundaries.

4. How can companies monitor security without invading employee privacy?

Use behavioral analytics and policy-based monitoring instead of invasive tracking. Focus on anomalies in data access, endpoint health, or cloud usage, rather than personal activity. Transparency in policies also helps build trust with remote teams.

5. What non-technical measures can improve remote security?

Non-technical essentials include establishing a remote-first security policy, providing regular employee training (especially on phishing and social engineering), promoting password hygiene, and fostering a culture of accountability without blame.
