Back to work, back to reality. The festive season is over, the Christmas tree is back in the loft, it’s time to go back to the office. They’ll be new strategies and protocols for 2025 - chief among them should be cyber security. Here’s what to consider when returning back to the office from a cyber security angle.
Returning to the office isn’t just about reclaiming desk space - it’s about safeguarding sensitive data in a world more digitally interconnected than ever before. But the transition can be seamless while reinforcing cyber security practices with a little attention to key areas.
The cyber security challenges of ‘Return to Work’ (RTO)
Device Diversification
Employees may be bringing laptops, tablets, and smartphones used during remote work back into the office. Many of these devices may not comply with corporate IT standards, introducing vulnerabilities.
Phishing and Social Engineering
Attackers target moments of transition. As employees shift back to office routines, they are more susceptible to phishing emails that appear to relate to new policies, hybrid work logistics, or health regulations.
Outdated Systems
Systems left idle or underused during remote work might be outdated, lacking critical security patches. Reintroducing these systems to the office network can create vulnerabilities.
Blended Environments
With hybrid work remaining popular, employees will toggle between home and office setups. Each switch increases the risk of data breaches, misconfigurations, or unsecured network connections.
Best practices for a secure return
Refresh and Educate Employees
Re-entry is the perfect time to reinforce cyber security or staff awareness training. Educate employees about recognising phishing emails, updating passwords, and securing personal devices. Use this as an opportunity to introduce simulated phishing exercises to sharpen awareness, and check out our staff awareness training option.
Zero Trust Approach
Implement a Zero Trust model - where no device or individual is trusted by default, even within the office network. This means continuous verification of all users and devices, no matter their location.
Mandatory Device Checks
Before reconnecting devices to the office network, ensure they undergo security audits. Update operating systems, patch vulnerabilities, and install endpoint security software to mitigate risks.
Multi-Factor Authentication (MFA)
MFA remains a cornerstone of robust cyber security. Require employees to use MFA for all critical systems, limiting access to sensitive data unless multiple forms of verification are completed.
Network Segmentation
Segment office networks to isolate vulnerable devices or users. This prevents a single point of compromise from spreading across the entire infrastructure.
Incident Response Plan Update
Review and update your incident response plan to reflect the realities of a hybrid workforce. Ensure that employees know how to report suspicious activity and that IT teams are equipped to handle potential breaches promptly.
Embracing the future of work securely
The return to office life must be approached with caution and foresight, even after a relatively short break. A balance of flexibility and security will define the success of this transition. By embedding cyber security into the core of RTO strategies, organisations can protect their assets, ensure employee productivity, and build a resilient workplace for the future.
Remember – cyber security is everybody’s responsibility. As we return to offices, let’s do so with vigilance and confidence.
