Keeping Your Business Cyber Secure During Summer Holidays

Why Summer Holidays Create Additional Cyber Security Risks

Summer should be a time for employees to recharge, but it can also create opportunities for cyber criminals. Reduced staffing levels, increased remote working, delayed response times, and employees connecting from airports, hotels, and public Wi-Fi networks can all increase a business’s exposure to cyber threats.

The challenge for small businesses is maintaining the same level of protection, with regular IT Support when key decision-makers and IT personnel may be away from the office. By planning ahead and implementing the right safeguards, organisations can enjoy the holiday season without compromising security.

The Cyber Security Threats Facing Small Businesses in 2026

AI-Powered Phishing Attacks Continue to Rise

Generative AI has dramatically improved the quality of phishing attacks. The spelling mistakes and obvious red flags that once made scam emails easy to identify have largely disappeared.

Attackers can now create highly convincing emails that mimic suppliers, colleagues, and senior management. During holiday periods, when teams are working with reduced staffing levels and covering for absent colleagues, these attacks can be particularly effective.

Regular cyber security training for employees helps staff recognise suspicious requests and verify unusual instructions through a secondary communication channel.

Smart Devices Are Often Forgotten

Modern businesses rely on connected technologies including CCTV systems, smart alarms, access control systems, printers, and IoT devices. Unfortunately, these systems are frequently overlooked when it comes to updates and security monitoring.

If left unsecured while offices are less occupied during the summer, they can provide an entry point for attackers. Professional MDR services London businesses rely on can help identify suspicious activity before it develops into a more serious incident.

Supply Chain Attacks Remain a Growing Concern

Cyber criminals increasingly target suppliers and third-party providers as a route into larger organisations. Holiday periods can make supply chain attacks even harder to detect, particularly when key contacts and approvers are unavailable.

Reviewing supplier access permissions and monitoring third-party connections should form part of every organisation’s summer cyber security checklist.

Essential Summer Holiday Cyber Security Measures

Adopt a Zero Trust Security Approach

The principle of Zero Trust Security is simple: never trust, always verify. Every user and device should be authenticated before accessing business systems, whether they are working from the office, home, or a holiday destination.

This significantly reduces the risk of unauthorised access during periods of increased remote working.

Strengthen Passwords, Patching and MFA

Before the holiday season begins, organisations should ensure that:

• Software updates have been applied.
• Operating systems are fully patched.
• Password policies are enforced.
• Multi-factor authentication (MFA) is enabled across critical systems.

These simple controls continue to prevent a significant proportion of cyber attacks.

Automate Security Monitoring

Cyber criminals do not take holidays, which means security monitoring cannot stop simply because staff are away.

Modern monitoring platforms use AI-driven analytics to detect suspicious behaviour and alert teams in real time. Many organisations also work with managed security service providers to ensure continuous protection throughout the summer months.

Securing Remote Workers During the Holidays

Mobile Device Management (MDM)

Employees often access company systems while travelling, working remotely, or checking emails on the move. Mobile Device Management helps organisations:

• Enforce encryption
• Apply security policies
• Protect business data
• Remotely wipe lost or stolen devices

This ensures sensitive information remains secure wherever employees are located.

Safe VPN and Wi-Fi Use

Public Wi-Fi networks in airports, hotels, cafés, and holiday rentals continue to pose significant risks. Employees should use a secure VPN whenever they access company resources remotely and avoid transmitting sensitive information over unsecured public networks.

Create a Holiday Incident Response Plan

A cyber incident that occurs during a fully staffed workweek is challenging enough. An incident during summer holidays can quickly become far more disruptive. Every business should have:

• Emergency contact details
• Escalation procedures
• Defined responsibilities
• Backup decision-makers
• Tested recovery processes

Preparing in advance ensures swift action if a security incident occurs.

Keeping Your Business Protected While Your Team Takes a Break

The best cyber security strategy is one that continues working even when employees are away. Automated monitoring, strong access controls, secure remote working policies, regular training, and robust backups all play an important role in maintaining business resilience throughout the summer.

By addressing the cyber security risks that become more common during holiday periods, businesses can reduce their exposure to threats and ensure employees can enjoy a well-earned break with confidence.
