Summer is a season of relaxation for many, but it’s also a prime opportunity for cybercriminals to strike. As IT and security teams operate with reduced staffing levels, attackers take advantage of slower response times and reduced oversight to launch targeted attacks that can easily go undetected.
The summer months are particularly vulnerable, with data indicating a 40% increase in cyberattacks during holiday periods. This is no coincidence – cybercriminals know that suspicious activity is more likely to go unnoticed when security teams are understaffed and on vacation. With smaller security teams covering the same workload, senior engineers taking planned time off, and institutional knowledge less accessible, operational bottlenecks arise across the organization.
Patch cycles get delayed, vulnerabilities remain unaddressed for longer, and investigations may not receive immediate attention. This creates an environment where common attacks like phishing and Business Email Compromise (BEC) can more easily succeed. As attackers increasingly use AI to make phishing attacks more convincing and scalable, traditional warning signs are becoming less reliable, making fraudulent requests harder to identify and more likely to succeed.
The real danger lies not just in the increased number of attacks during vacation periods, but also in the fact that lean staffing can make it harder for employees to verify urgent requests or question suspicious emails. With approval chains disrupted and key decision makers out of the office, attackers have more opportunities to impersonate executives, vendors, or trusted contacts to steal credentials or divert funds.
If these attacks succeed, reduced coverage can delay detection and response, giving attackers more time to operate undetected – a phenomenon known as dwell time. The longer attackers remain inside a network, the more opportunities they have to steal credentials, access sensitive data, move laterally, or launch a ransomware attack.
The problem is not just that vacation schedules are disrupted; it’s also that many security operations still rely heavily on human availability. Alert fatigue worsens when teams are understaffed, and manual processes become bottlenecks. Critical functions like ticket triage, threat investigations, patch deployment, and containment actions all require time and attention – and when staffing levels are reduced, these processes slow down.
To mitigate this risk, organizations need to prioritize automation, monitoring, and response capabilities that can maintain strong protection even when key personnel are out of the office. By unifying security data into actionable insights, IT teams can reduce fatigue and improve faster, more accurate detection and response. This requires a shift away from relying on human availability and towards leveraging technology to stay ahead of evolving cyberthreats.
Ultimately, the summer months present an opportunity for organizations to reassess their security posture and invest in solutions that can maintain strong protection even when staffing levels are reduced. By doing so, they can minimize the risk of attacks taking advantage of vacation schedules and ensure a safer environment for employees and assets alike.
