How to Secure Personal Devices in the Workplace: Best Practices Leveraging Stellar Cyber and SentinelOne

The rise of remote work and Bring Your Own Device (BYOD) policies has reshaped workplace security.

While enabling flexibility, personal devices often lack the strict security standards of corporate assets, increasing cyberattack risks.

For ISO 27001:2022-certified SOC teams, securing these devices without harming productivity is essential.

This article explores how Stellar Cyber’s Open XDR and SentinelOne’s AI-powered endpoint protection can help secure personal devices effectively.

The Risks of Personal Devices

  • Inconsistent Patch Management: Delayed or skipped updates leave devices vulnerable.
  • Insecure Networks: Public Wi-Fi increases the risk of data interception.
  • Malware Introduction: Devices can become infected outside corporate controls.
  • Data Leakage: Sensitive data on personal devices can be exposed or stolen.
  • Device Theft or Loss: Stolen or lost devices can result in unauthorized data access.

The BYOD model increases the attack surface, requiring enhanced visibility and control mechanisms.

Stellar Cyber’s Role in Securing Personal Devices

Stellar Cyber’s Open XDR platform provides unified visibility by aggregating telemetry across endpoints, networks, cloud, and applications.

  • Device Behavior Analytics: Uses AI to detect anomalies on devices connected to corporate networks.
  • Contextual Correlation: Correlates data across multiple vectors to highlight high-risk activities and reduce false positives.
  • Automated Response: Automatically isolates compromised devices to prevent lateral movement.

This approach ensures SOC teams maintain visibility and control without being intrusive.

SentinelOne Endpoint Protection on Personal Devices

SentinelOne leverages behavioral AI to enhance endpoint protection, particularly on personal devices.

  • Lightweight Agent: Operates with low system impact to ensure user compliance.
  • Real-Time Behavioral Detection: Detects threats like ransomware by analyzing behavior, not just signatures.
  • Automated Remediation: Neutralizes threats and restores system changes automatically.
  • Device Health Monitoring: Ensures devices meet compliance standards for secure access.

Integration with VAPT and GRC Teams

  • Vulnerability Assessment and Penetration Testing (VAPT): Tools like Tenable.io, Burp Suite, and SentinelOne Cloud Security help detect, assess, and remediate vulnerabilities across environments.
  • Governance, Risk, and Compliance (GRC): GRC teams define BYOD policies aligned with ISO 27001:2022 to ensure secure and compliant usage.

Collaboration between SOC, VAPT, and GRC ensures comprehensive and evolving protection.

Best Practices for Securing Personal Devices

  1. Strong Authentication: Enforce Multi-Factor Authentication (MFA) for device access.
  2. Device Compliance Checks: Validate device security baselines before granting access using Stellar Cyber.
  3. Endpoint Protection Deployment: Require SentinelOne agents on all personal devices.
  4. Network Segmentation: Place personal devices on isolated VLANs to contain threats.
  5. User Awareness Training: Educate users on phishing and secure practices.
  6. Data Encryption: Ensure encryption of both stored and transmitted sensitive data.
  7. Regular Auditing: Conduct regular checks for compliance and timely patching.

Alignment with ISO 27001:2022

ISO 27001:2022 requires risk-based controls and ongoing monitoring.

It emphasizes documented policies under Annex A.8 (Asset Management) and A.9 (Access Control), making secure personal device practices essential for certification and resilience.

Conclusion

Securing personal devices in today’s hybrid work environment demands advanced tools, clear policies, and continuous monitoring.

With Stellar Cyber’s unified visibility and SentinelOne’s automated protection, SOC teams can enforce strong security without sacrificing productivity.

Working closely with VAPT and GRC teams further ensures compliance with ISO 27001:2022 and protects organizational assets.

Final Thoughts

Cybersecurity is not a one-time task—it’s a continuous process in a landscape of ever-changing threats. As technology progresses, so do the tactics of cybercriminals. Organizations must stay one step ahead through proactive strategies.

Robust security depends on layered defenses, informed decisions, and a culture of awareness. No single tool guarantees safety—but combining smart technologies, strong policies, and skilled teams significantly reduces your risk exposure.

🛡️ Don’t rely on employees as your last line of defense.
